'It's Snowing on Jupiter': Stunning Photos Show Clouds High in Gas Giant's Skies. Error loading player: No playable sources found Not all of Jupiter's clouds are huge, swirling, otherworldly beasts.
Spectacular new images captured by NASA's Jupiter-orbiting Juno spacecraft show fluffy-looking white clouds casting their comparably tiny shadows on the giant planet's monstrous, multicolored cloud decks. The white clouds, which get up to 50 miles (80 kilometers) wide or so, are high up in Jupiter's atmosphere — so high that they're very cold, and the material they shed is therefore almost certainly frozen, Juno team members said. "It's snowing on Jupiter, and we're seeing how it works," Juno principal investigator Scott Bolton, of the Southwest Research Institute in San Antonio, said during a news conference Thursday (May 25). [Related: New Mysteries at Jupiter] "It's probably mostly ammonia ice, but there may be water ice mixed into it, so it's not exactly like the snow that we have [on Earth]," Bolton added. NASA shake tests the Orion capsule that could take man to Mars. The capsule, which could one day man to the red planet, has been put through its paces on the world's most powerful vibration table to simulate launch.
Nasa has revealed the latest test to ensure its Orion capsule will be able to survive launching on top of the world's most powerful rocket. Engineers at NASA Glenn's Plum Brook Station in Sandusky, Ohio recently finished a series of tests on a full-size test version of Orion's service module to verify that it can withstand the vibrations it will experience when it launches and travels into space atop the Space Launch System (SLS) rocket.

Monster Black Hole Is the Largest and Brightest Ever Found.
Astronomers have discovered the largest and most luminous black hole ever seen — an ancient monster with a mass about 12 billion times that of the sun — that dates back to when the universe was less than 1 billion years old.
It remains a mystery how black holes could have grown so huge in such a relatively brief time after the dawn of the universe, researchers say. Supermassive black holes are thought to lurk in the hearts of most, if not all, large galaxies. The largest black holes found so far in the nearby universe have masses more than 10 billion times that of the sun. In comparison, the black hole at the center of the Milky Way is thought to have a mass only 4 million to 5 million times that of the sun. Blue Origin.

November 30, 2012 SNR 0509-67.5, a supernova remnant in the LMC Image Credit: X-ray: NASA/CXC/SAO/J.Hughes et al, Optical: NASA/ESA/Hubble Heritage Team (STScI/AURA) SNR 0509-67.5 (SNR 0509 for short) is the remnant of a supernova explosion in the Large Magellanic Cloud, located some 160,000 light-years away in the constellation of Dorado.
It is about 23 light-years across and expanding at more than 5,000 kilometers a second, or more than 18 million kilometers an hour. This bubble is the visible remnant of a Type 1a supernova that occurred about 400 years ago in Earth’s time frame (what means that the light from the explosion reached us about 400 years ago), which was unusually bright and energetic. A Type Ia supernova is a result from the violent explosion of a white dwarf star (a compact star that has ceased fusion in its core). Astronomers failed to find any remnant of the companion star, however, and concluded that the common scenario of Type Ia supernovae did not apply in this case.
