Lowell Observatory 5 Aug 2020, 09:41 UTC The passing of July to August signals the arrival of one of the most prominent and reliable meteor showers, the Perseids.
Universe Today 4 Aug 2020, 20:00 UTC No matter which direction you look in the Universe, the view is basically the same if you look far enough. Our local neighborhood is populated with bright nebulae, star clusters, and dark clouds of gas and dust. There are more stars toward the center of the Milky Way than there are in other directions. But across millions, and billions, of light-years, galaxies cluster evenly in all directions, and everything starts to look the same. In astronomy, we say the Universe is homogeneous and isotropic. Put another way, the Universe is smooth.
Bad Astronomy 4 Aug 2020, 13:00 UTC We know that planets like the ones in our solar system form in flat disks of gas and dust called protoplanetary disks. We can actually see that happening all over the galaxy. But a team of astronomers wondered if that were the only place they could be born. So they figured why not see if planets can form in the very worst place you can imagine in the entire Universe: Near a supermassive black hole.
Universe Today 4 Aug 2020, 08:03 UTC On Thursday, July 30th, NASA launched the most sophisticated Mars rover ever built atop a United Launch Alliance (ULA) Atlas V rocket from Space Launch Complex 41 at Cape Canaveral Air Force Station, Florida.This mission includes the Perseverance rover (Curiosity‘s sister vehicle) and the Ingenuity Mars Helicopter, both of which are being flown on a seven-month journey by the Mars 2020 spacecraft.
Astronomy Now 3 Aug 2020, 18:17 UTC As NASA’s Perseverance Mars rover hurtles toward the red planet to search for signs of ancient microbial life in river delta and lakebed deposits, new research indicates many of the valley networks scarring the surface of Mars were caused by water melting under glacial ice, not by free-flowing rivers.
Chandra X-ray Observatory Blog 3 Aug 2020, 14:22 UTC Galaxy clusters are an exceptional class of object – they are the largest structures in the Universe held together by gravity, and contain hundreds or thousands of individual galaxies, unseen dark matter, and a vast amount of hot gas that gives off X-rays.
The Planetary Society Blog 31 Jul 2020, 14:30 UTC NASA’s Hubble Space Telescope recently captured this beautiful new picture of Saturn. Scientists regularly image the outer planets with the telescope to see how their atmospheres change over time. Image credit: NASA et al.
