For the first time, scientists have detected neutrinos coming from the Sun’s core that got their start via the CNO process, an until-now theorized type of stellar nuclear fusion. This is really cool, but it’ll take a bit of explaining.
After nearly a century, elusive CNO neutrinos are finally seen from the Sun

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.

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.
Because the Universe isn't weird enough: Black hole planets may exist.

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.

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.

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.
