Unprecedented wildfires burn in the Arctic during heatwave
The Arctic Circle is suffering from an unprecedented number of wildfires in the latest sign of a climate crisis. With some blazes the size of 100,000 football pitches, vast areas in Siberia, Alaska and Greenland are engulfed in flames. The World Meteorological Organisation has said these fires emitted as much carbon dioxide in a month as the whole of Sweden does in a year.

Massive Sinkhole Documentary - World's Most Terrifying Sinkhole - Documentary HD
Massive Sinkhole Documentary - World's Most Terrifying Sinkhole - Documentary HD Sinkholes may vary in size from 1 to 600 m (3.3 to 2,000 ft) both in diameter and depth, and vary in form from soil-lined bowls to bedrock-edged chasms. Sinkholes may be formed gradually or suddenly, and are found worldwide. On 2 July 2015, scientists reported that active pits, related to sinkhole collapses and possibly associated with outbursts, have been found on the comet 67P/Churyumov-Gerasimenko by the Rosetta space probe. Sinkholes may capture surface drainage from standing or running water, but may also form in high and dry places in specific locations. The formation of sinkholes involves natural processes of erosion  or gradual removal of slightly soluble bedrock (such as limestone) by percolating water, the collapse of a cave roof, or a lowering of the water table. Sinkholes often form through the process of suffosion. Thus, for example, groundwater may dissolve the carbonate cement holding the sandstone particles together and then carry away the lax particles, gradually forming a void. Occasionally a sinkhole may exhibit a visible opening into a cave below. In the case of exceptionally large sinkholes, such as the Miny?© sinkhole in Papua New Guinea or Cedar Sink at Mammoth Cave National Park in Kentucky, an underground stream or river may be visible across its bottom flowing from one side to the other. Sinkholes are common where the rock below the land surface is limestone or other carbonate rock, salt beds, or in other rocks, such as gypsum,  that can be dissolved naturally by circulating ground water. Sinkholes also occur in sandstone and quartzite terrains. As the rock dissolves, spaces and caverns develop underground. These sinkholes can be dramatic, because the surface land usually stays intact until there is not enough support. Then, a sudden collapse of the land surface can occur. Sinkholes may capture surface drainage from standing or runni

What You Should Know About Getting a Career In Astronomy/Astrophysics
This video will cover how to get into space research (such as astrophysics or astronomy) and some research that is going on. For those looking into space related majors, your best options are astronomy and astrophysics. However, as an undergrad you will usually just start as a physics major then pick a more specific discipline in grad school. You also will need to get a PhD if you want to do work in astrophysics or astronomy. There really aren't jobs in these fields for those with just bachelor's degrees. Although the field is very competitive, if you have a true interest for the subject, most people will tell you to pursue it. Even if you don't land a job that you want, astrophysicists and astronomers can find work in other fields such as finance, engineering, software development, teaching, and more. ***************************************************

A Day In The Life Of An Astronomer
Many people think that professional astronomers spend their days gazing up at the night sky through a telescope. But this is far from reality. In this video, I'll show you what a professional astronomer does at work in a typical day and explain why it's much more interesting than simply staring through a telescope.

Observatory – An Astronomer’s Window to the Stars – Sanctuary – S1E4
Jonathan Fay's fascination with outer space began the first time he looked through a telescope. With a little help from his family, the amateur astronomer designed and built his own observatory – right in his backyard! Today, he can be found observing planetary nebula and galaxies from his 8-foot dome. This is the fourth episode of Sanctuary, a new Zillow series profiling individuals who took their passions to new levels by building out their space to do what they love most.

The Best Telescope for BEGINNERS (Visual Astronomy)
The Best Telescope for Beginners: Buying your first astronomy telescope is a step towards a new level of appreciation for the night sky. Almost 8 years ago, I bought my first telescope - a Dobsonian reflector - just like this one (just smaller). The experiences I had with this telescope early on propelled my love for astronomy. I believe that an 8-inch Dob, like the one featured in this video (Apertura AD8), is the best telescope a beginner could start with.

Neutron Stars: Crash Course Astronomy #32
In the aftermath of a 8 – 20 solar mass star’s demise we find a weird little object known as a neutron star. Neutrons stars are incredibly dense, spin rapidly, and have very strong magnetic fields. Some of them we see as pulsars, flashing in brightness as they spin. Neutrons stars with the strongest magnetic fields are called magnetars, and are capable of colossal bursts of energy that can be detected over vast distances.

Would Earth Survive If a Black Hole Entered Our Solar System
Our solar system is made up of eight planets, hundreds of natural satellites like moons, thousands of asteroids, and billions of comets. This beautiful space cocktail is constantly moving around our sun. But it could all be torn apart if just one stray black hole decided to drop by… Yes, there’s been a lot of talk about black holes lately since Kathrine Bouman figured out how to take a picture of one. The closest black hole to our solar system is 10 to 13 times the mass of our sun, and it’s located 3,000 light years away. But what would happen if a black hole came into our solar system?

Real Images from the Solar System!
Dear World, Back to space! This should be a reminder of how far we have come, and how much there is still to explore. Our species has its eyes in the solar system, while we still stay at home for now. While we perform incredible tasks in exploring, the results sometimes vanish in the huge mess of information we devour daily. No wonder people are wondering what is reality and what is fake. Because it takes time to find out and understand. People who do not care will believe what they want anyway. Of course there is tons of interesting data, but there is a huge interest in pictures, because they transport a feeling of being there. It really shows that we want to go.

The Solar System Is Not Like You Think It Is
The Earth is round, Mercury is the hottest planet, and the Sun is yellow. It would seem that these are all simple, undeniable facts known even to those with no real knowledge of astronomy. However, it’s time to think again. TIMESTAMPS Does the Moon have a dark side? 0:23 Is the temperature of Mercury higher than on other planets? 1:01 Is the Sun just a big ball of fire? 2:01 Is the Sun really yellow? 2:50 Would a human being explode in space without a space suit? 3:41 Is the Earth further from the Sun in winter than in summer? 4:48 Is the Earth perfectly spherical? 6:03 SUMMARY - The Sun shines and warms both the visible and invisible parts of the Moon. The truth is that the period the Moon takes to revolve on its axis coincides with the amount of time it takes to orbit the Earth. That’s why we only see one side of it. - Mercury is closest to the Sun; therefore, its surface temperature must be higher than all the other planets. However, the hottest planet in the Solar System is actually Venus, despite the fact it’s 31,070,000 miles (50 million km) further away from the Sun than its neighbor. - What we think of as fire is, in fact, energy in the form of heat and light, produced by the thermonuclear reactions occurring in the star’s core. A thermonuclear reaction involves changing some elements into others, and it’s accompanied by the ejection of heat and light energy. - Why do human eyes see the Sun as yellow? It’s all down to Earth’s atmosphere. As is well known, light which has a long wavelength, in the yellow and red part of the spectrum, passes through the atmosphere best of all. Light in shorter wavelengths, in the green to violet part of the spectrum, gets dissipated to a greater degree by the atmosphere. - Our skin is flexible enough to keep all of our internal organs in place. The walls of the blood vessels would also prevent the blood from boiling thanks to their elasticity. Moreover, in the absence of external pressure in the space en

Solar System Video
Solar System Video showing the 8 planets of the Solar System orbiting the Sun. As we move out from Mercury, Venus, Earth and Mars, towards the gas giant planets of the outer Solar System, each of the planets take longer to orbit the sun. The planets in order of size are; Mercury Mars Venus Earth Neptune Uranus Saturn Jupiter When listed in terms of distance from the Sun, the order is as follows; Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune. All of the planets orbit the Sun in an anti-clockwise direction. Most also rotate on their axis in an anti-clockwise direction. The exceptions to this rule are; Uranus - Which rotates on it's end like a bowling ball Venus - Which rotates clockwise, but very slowly. Venus rotates so slowly that a day on planet Venus is longer than a year! The planet with the fastest rotation in Jupiter, which rotates every 10 hours. So fast that it causes the planet to flatten out a little. In this Solar System video, the distance between the planets is not to scale. In the real Solar System the distances are vast. The size of the planets in this Solar System video is also just an indication of their relative size. In reality Jupiter is many more times the size of the Earth. The planets would also not create shadows on each other as they do in this video. Other bodies that exist in the Solar System but are not included in this Solar System video include, The Dwarf Planets (of which Pluto is one), The asteroid belt (which sits between the orbit of Mars and Jupiter), and the Ort Cloud (which sits beyond the orbit of Neptune)

What's Inside A Black Hole?
What's Inside A Black Hole? Subscribe: holes are mysterious and bizarre objects in the universe that really have no explanation. In fact, we hardly know anything about what lies inside of a black hole. We know and understand what we see on the outside of a black hole, but we have no way of going inside one to take a look at what is really happening. Even if we sent a probe inside a black hole, it would not survive the journey, and there would be no way that the probe could transmit a signal outside once it had been sucked inside. This is because a black hole is the product of mass being squeezed together so densely, and so tightly, that it creates a gravitational pull that is so strong, that not even light can escape its grasp. Supermassive black holes with masses millions to billions of times that of the sun are thought to lurk at the hearts of all galaxies in the universe. You may notice that when you see a photo of a spiral galaxy, such as the Milky Way, in the center of the galaxy is a giant mass of light, which many people would think looks like a massive sun. But this is not light coming from the black hole itself. Remember, that light cannot escape the heavy gravitational pull. Instead, the light we see comes from the magnetic fields near a spinning black hole that propel electrons outward in a jet along the rotation axis. The electrons produce bright radio waves. Quasars are believed to produce their energy from massive black holes in the center of the galaxies in which the quasars are located. Because quasars are so bright, they drown out the light from all the other stars in the same galaxy. You’re probably asking, ‘well, what’s a quasar?’ A Quasar is the short name for ‘quasi-stellar object’ and is a very highly energetic object surrounding an actively feeding Supermassive Black Hole. In more basic terms, the Supermassive Black Hole in the middle of a galaxy feeds intermittently. As it feeds, gas swirls around i

The First Ever Black Hole Image Finally Released
It was the image that broke the Internet in April 2019. The subject? One that had managed to evade the paparazzi for as long as people have theorized about its existence. It was the first photo ever taken of a black hole! It's a monumental event, not only for scientists but for the public too! Up until recently, black holes had only technically been a theory. Well, astronomers were pretty sure they exist. For decades they’ve been watching the pull and push of black holes that influenced neighboring planets and stars. They’ve even been listening to the powerful gravitational waves that appear after supermassive black holes collide. But up till now, astrophysicists have always lacked that final proof of their existence.

Why this black hole photo is such a big deal
This is an updated version of a video we published in 2016 about the Event Horizon Telescope, an international collaboration to image a black hole for the first time in human history. On April 10, 2019, the team announced their results: They had successfully imaged the supermassive black hole in the center of the galaxy m87, which is nearly 54 million light-years away from us. They were able to achieve unprecedented resolution using very long baseline interferometry, which combines the observations of multiple radio telescopes across the globe. The team wanted to find out whether Einstein's Theory of General Relativity holds up in the extreme environment of black holes, and the results do, in fact, seem to be consistent with the predictions. In the future, we may see more and shaper images of black holes as the team targets smaller wavelengths of light and recruits more telescopes. Eventually, they may include an orbiting space telescope.

This Black Hole is Coming Towards Earth!
Andromeda is a spiral galaxy, located 2.5 Million light-years away from us. At the centre of this galaxy there is a massive Black Hole. This Black Hole is so big that it's 100 million times massive than our sun. According to scientists, this Black Hole is coming towards us with the speed of 110 km per second. In 4.5 billion years from now andromeda will collide with our galaxy and when that happens, this Black Hole may hit the Earth.

How to Understand the Image of a Black Hole
We have just seen the first image of a black hole, the supermassive black hole in the galaxy M87 with a mass 6.5 billion times that of our sun. But what is that image really showing us? Using my every day intuition I wondered: will we see the "shadow" of the black hole even if we're looking edge on at the accretion disk? The answer is yes because the black hole warps space-time, so even if we wouldn't normally be able to see the back of the accretion disk, we can in this case because its light is bent up and over the black hole. Similarly we can see light from the bottom of the back of the accretion disk because it's bent under the bottom of the black hole. Plus there are additional images from light that does a half turn around the black hole leading to the inner rings. What about the black hole "shadow" itself? Well initially I thought it can't be an image of the event horizon because it's so much bigger (2.6 times bigger). But if you trace back the rays, you find that for every point in the shadow, there is a corresponding ray that traces back to the event horizon. So in fact from our one observing location, we see all sides of the event horizon simultaneously! In fact infinitely many of these images, accounting for the virtually infinite number of times a photon can orbit the black hole before falling in. The edge of the shadow is due to the photon sphere - the radius at which light goes around in closed orbits. If a light ray coming in at an oblique angle just skims the photon sphere and then travels on to our telescopes, that is the closest 'impact parameter' possible, and it occurs at sqrt(27)/2*r_s

NASA Captured First Ever Image of a Black Hole!
Black Holes are known to swallow everything coming in their path but that's not the end. With time they they emit enormous amounts of energy. In 2015 Hubble Telescope captured something that shocked the entire world. It was a burst of plasma jet 260 million light years away in space coming from an unknown source. Calculations showed that the jet was travelling at 98% the speed of light. Scientists finally concluded that they have captured a plasma burst coming from a super-massive Black Hole. Which is located inside a galaxy 260 million light-years away.

NASA Captured A Black Hole Destroying Star!
For the very first time NASA captured a black hole while it was ripping apart a star. In 2005, Astronomers saw a energy jet coming from 150 Million light-years away. It was moving at one-fourth the speed of light. They studied it for more than a decade and concluded that it is coming from a super-massive Black Hole which is 20 million times bigger than our sun. As black Hole was eating the star, this energy burst was being erupted.

Black Holes: Crash Course Astronomy #33
We’ve covered a lot of incredible stuff, but this week we’re talking about the weirdest objects in space: BLACK HOLES. Stellar mass black holes form when a very massive star dies, and its core collapses. The core has to be more than about 2.8 times the Sun’s mass to form a black hole. Black holes come in different sizes, but for all of them, the escape velocity is greater than the speed of light, so nothing can escape, not matter or light. They don’t wander the Universe gobbling everything down around them; their gravity is only really intense very close to them. Tides near a stellar mass black hole will spaghettify you, and time slows down when you get near a black hole — not that this helps much if you’re falling in.

What is Space Time and How it Works | Documentary
The time scale of the universe is very long compared to that for human life. It was therefore not surprising that until recently, the universe was thought to be essentially static, and unchanging in time. On the other hand, it must have been obvious, that society is evolving in culture and technology. This indicates that the present phase of human history can not have been going for more than a few thousand years. Otherwise, we would be more advanced than we are. It was therefore natural to believe that the human race, and maybe the whole universe, had a beginning in the fairly recent past. However, many people were unhappy with the idea that the universe had a beginning, because it seemed to imply the existence of a supernatural being who created the universe. They preferred to believe that the universe, and the human race, had existed forever. Their explanation for human progress was that there had been periodic floods, or other natural disasters, which repeatedly set back the human race to a primitive state. This argument about whether or not the universe had a beginning, persisted into the 19th and 20th centuries. It was conducted mainly on the basis of theology and philosophy, with little consideration of observational evidence. This may have been reasonable, given the notoriously unreliable character of cosmological observations, until fairly recently. The cosmologist, Sir Arthur Eddington, once said, 'Don't worry if your theory doesn't agree with the observations, because they are probably wrong.' But if your theory disagrees with the Second Law of Thermodynamics, it is in bad trouble. In fact, the theory that the universe has existed forever is in serious difficulty with the Second Law of Thermodynamics. The Second Law, states that disorder always increases with time. Like the argument about human progress, it indicates that there must have been a beginning. Otherwise, the universe would be in a state of complete disorder by now, and everything would be

Colossal Black Holes - Astronomy Documentary on the Universe's Gargantuan Black Holes HD
A black hole is a mathematically defined region of spacetime exhibiting such a strong gravitational pull that no particle or electromagnetic radiation can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary of the region from which no escape is possible is called the event horizon. Although crossing the event horizon has enormous effect on the fate of the object crossing it, it appears to have no locally detectable features. In many ways a black hole acts like an ideal black body, as it reflects no light. Moreover, quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is on the order of billionths of a kelvin for black holes of stellar mass, making it essentially impossible to observe. Objects whose gravitational fields are too strong for light to escape were first considered in the 18th century by John Michell and Pierre-Simon Laplace. The first modern solution of general relativity that would characterize a black hole was found by Karl Schwarzschild in 1916, although its interpretation as a region of space from which nothing can escape was first published by David Finkelstein in 1958. Long considered a mathematical curiosity, it was during the 1960s that theoretical work showed black holes were a generic prediction of general relativity. The discovery of neutron stars sparked interest in gravitationally collapsed compact objects as a possible astrophysical reality. Black holes of stellar mass are expected to form when very massive stars collapse at the end of their life cycle. After a black hole has formed, it can continue to grow by absorbing mass from its surroundings. By absorbing other stars and merging with other black holes, supermassive black holes of millions of solar masses (M?) may form. T

The 1995 Hubble photo that changed astronomy
The Hubble Deep Field, explained by the man who made it happen. If you hold a pin at arm’s length up in the air, the head of the pin covers approximately the amount of sky that appears in the Hubble Deep Field. The iconic 1995 image is crowded, not because it’s a broad swath of sky but because it’s a broad swath of time. The Hubble Deep Field is more than 12 billion light-years deep. Robert Williams was the director of the Hubble’s science institute back in 1995, and it was his decision to attempt a deep field observation with the telescope. Previous calculations had indicated that Hubble would not be able to detect very distant galaxies, but Williams figured they’d never know unless they tried. His team chose a completely dark part of the sky, in order to see beyond the stars of the Milky Way, and programmed Hubble to stare at that spot for 10 days. It was unusual to use precious observing time to point the telescope at nothing in particular, but that’s what they did. "We didn’t know what was there, and that was the whole purpose of the observation, basically — to get a core sample of the universe," Williams said, borrowing the concept of the "core sample" from the earth sciences. "You do the same thing if you're trying to understand the geology of the Earth: Pick some typical spot to drill down to try to understand exactly what the various layers of the Earth are and what they mean in terms of its geologic history." What makes the Hubble Deep Field an atypical core sample is that rather than observing the material as it is now, the telescope collected images of galaxies as they appeared millions and billions of years ago. Since light can only travel so fast, the telescope is a peephole into the history of the universe.

Distances: Crash Course Astronomy #25
How do astronomers make sense out of the vastness of space? How do they study things so far away? Today Phil talks about distances, going back to early astronomy. Ancient Greeks were able to find the size of the Earth, and from that the distance to and the sizes of the Moon and Sun. Once the Earth/Sun distance was found, parallax was used to find the distance to nearby stars, and that was bootstrapped using brightness to determine the distances to much farther stars.

Light: Crash Course Astronomy #24
In order to understand how we study the universe, we need to talk a little bit about light. Light is a form of energy. Its wavelength tells us its energy and color. Spectroscopy allows us to analyze those colors and determine an object’s temperature, density, spin, motion, and chemical composition.

Dark Matter: Crash Course Astronomy #41
Today on Crash Course Astronomy, Phil dives into some very dark matters. The stuff we can actually observe in the universe isn’t all there is. Galaxies and other large structures in the universe are created and shifted by a force we detect mostly indirectly, by observing its impact: DARK MATTER.
