We’ve established by now that black holes are weird. The result of absolute gravitational collapse of a massive body: a point of hypothetical infinite density surrounded by an event horizon. At that horizon time is frozen and the fabric of space itself cascades inwards at the speed of light. Nothing can travel faster than light, and so nothing can escape from below the event horizon- not matter, not light, not even information.

Don’t get me wrong; the math is complicated. But the objects themselves are simple. In fact every black hole in the universe, no matter how it formed or what happened to it afterwards, can be perfectly described with only three properties. Those properties are mass, angular momentum, and electric charge. Or at least this is the proposition behind the famous no-hair conjecture, or no-hair theorem.

Mars Reconnaissance Orbiter Inverted Features and Layers

Astronauts on the International Space Station get food that’s carefully chosen for its nutritional value and specially prepared and packaged to be easily accessible to them in a weightless world on orbit. Could the same food feed the needs of people stuck on planet Earth? We conducted an experiment to find out how well two regular people could get by eating only astronaut food for a full week—a week that included a holiday weekend feast, just to up the difficulty factor. Could they resist the lure of their favorite foods? Take a look at how they fared… HD Download: https://archive.org/details/jsc2018m000103_Eat_Like_an_Astronaut ___________________________ FOLLOW THE SPACE STATION!

President Donald Trump told space industry notables that he's directing the Department of Defense (DoD) to create a Space Force: a sixth branch of the military that sounds straight of a sci-fi movie. "We are going to have the Air Force and we are going to have the Space Force — separate but equal," Trump said during an address to the National Space Council meeting on Monday. "It is going to be something. So important." Trump has spoken publicly about creating a Space Force four times since becoming president. The idea is also part of the 2018 National Defense Authorization Act, which became law in December 2017. The law defines the space force as "a separate military department responsible for the national security space activities," and it asks the DoD to submit a final plan for the Space Force's structure and functions by December 31, 2018. But retired NASA astronaut Mark Kelly — a former Navy pilot, combat veteran, four-time space-flyer, and the identical twin brother of fellow former astronaut Scott Kelly — doesn't support it, and some members of Congress are also voicing their distaste for the idea. "This is a dumb idea. The Air Force does this already. That is their job," Mark Kelly tweeted on Monday after reading a story on Military.com. "What's next, we move submarines to the 7th branch and call it the 'under-the-sea force?'" http://www.businessinsider.com/trump-space-force-is-dumb-says-nasa-astronaut-2018-6 http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

President Donald Trump directed the formation of a new military branch dedicated to fighting in outer space, called Space Force, that would be separate but equal to the the US Air Force during a meeting of his National Space Council.

The first video shows an active region on the Sun (with an inset Earth, for size reference) taken in extreme ultraviolet, or EUV, light by the Solar Dynamics Observatory. The EVE sounding rocket supports the calibration of EUV measurements taken by spacecraft to make sure the data they provide are accurate. With the usual focus on satellite-based solar imagery, one often forgets about the important contributions of ground-based observatories. Here we present a video of imagery collected at the Big Bear Solar Observatory (BBSO) site of the National Solar Observatory (NSO). The light from the Sun is passed through a filter that admits light from the hydrogen alpha spectral line (6562.8 angstroms or 656.28 nanometers) in the red region of the spectrum. This reveals many details which cannot be seen in our usual broad-spectrum view of the Sun, particularly filaments across the solar disk and limb. Ground-based observatories are subjected to a number of challenges different from their space-based counterparts, including gaps in the visibility of their target (i.e. nighttime), clouds (some slightly visible in this movie) and atmospheric turbulence (also some visible here). The spectral line for hydrogen alpha is a deep red and rather dark for regular digital displays. For this visualization, we have used a brighter 'blackbody' colour table to improve visibility.

Today we take a trip inward, to explore Sun-Scorched Mercury. Visit our sponsor, Brilliant: https://brilliant.org/IsaacArthur/ Mercury is the nearest planet to the Sun, a seeming airless wasteland little discussed in conversations about colonizing our solar system. Today we will challenge that, and show that Mercury may be one of the most promising places for humanity to make new homes on.

Naturalist and author Bernie Taylor presents an origin to modern astronomy in European Paleolithic caves from 34,000 years ago that connects with global myths of hunter-gatherers and the ancients in the Mediterranean region. Taylor proposes that astronomy was developed to pass on timeless myths and cultural traditions among prehistoric hunter-gathers. He will explore deep sources to Ptolemy's Almagest and the hero's journey monomyth of Joseph Campbell as popularized in the Star Wars movie series, and test the precession of the equinoxes against the Paleolithic record.
