Antares and Clouds by Ivan Eder, NASA: Antares is a red supergiant and is about 850 times the diameter of our own Sun, 15 times more massive, and 10,000 times brighter. It is seen on the left surrounded by a nebula of gas which it has itself exploded. To the lower right is M4 and on the far right the bright star is Al Niyat. #Astronomy #Antares # Ivan_Eder #NASA
With a long exposure from a dark location, though, the dust cloud surrounding the Pleiades star cluster becomes very evident. The above exposure took about 30 hours and covers a sky area several times the size of the full moon. Also known as the Seven Sisters and M45, the Pleiades lies about 400 light years away toward the constellation of the Bull (Taurus). The number of Pleiades stars visible may be more or less than seven, depending on the darkness of the surrounding sky.
Tiny tardigrades, also called water bears are the first animals known to survive the pitiless rigors of space, including hard vacuum, cosmic rays, freezing cold and solar UV rays 1,000 times as strong as those experienced on Earth's surface. ... "They have claws and eyes. They are real animals. And this is the first time such an animal was tested in space," said Petra Rettberg
Death Star: Eta Carinae, one of the closest stars to Earth is huge and unstable and will likely explode in a supernova in the relatively 'near future' (On an astronomical timeline this could be a million years from now). via NASA #Eta_Carinae #Supernova #NASA
Central area of the Milky Way galaxy, released by astronomers at the European Southern Observatory's Paranal Observatory in Chile. The photo shows 84 million stars in an image measuring 108,500×81,500, which contains nearly 9 billion pixels, and is actually a composite of thousands of individual photographs shot with the observatory's VISTA survey telescope.
