Remember the big solar storm back in May 2024? The one that caused auroras as far south as Florida and Mexico? Scientists are still parsing out the impacts that storm had on the local environment, and a new paper published in Geophysical Research Letters by Yoshizumi Miyoshi of N

The torrent of corona related discoveries keeps coming. Lately we’ve covered a variety of potential solutions to the “coronal heating problem” - why the Sun’s corona is so much hotter than its surface. Now, a paper led by a team of researchers from the University of Newcastle, In

There weren’t any humans strapped into the bucket seats of the Orion spacecraft for the Artemis I mission. But there were two anthropomorphic mannequins made to mimic human bone and soft tissue, but also equipped with hundreds of radiation sensors spread throughout their body as

A history of a planet’s volcanic activity is contained in its rocks. And Mars’ rocks - or at least many of the meteorites that have made the journey from it to Earth - were telling a contradictory story. They appeared to be highly oxidized, but our understanding of the internal v

The magnetic environment around the Sun is a jumbled mess of chaotic fields and streams of charged particles. Recently we’ve been getting at least slightly better at mapping out its complexity, thanks in large part to data collected by missions like the Parker Solar Probe and Sol

Unlike the Moon, the Sun is constantly rotating from our perspective - but we still only see half of it at any given time. Since it takes 27 days to complete a full rotation, that leaves plenty of time for changes to happen to the side we can’t see that could directly impact Eart

Typically, when we think of exoplanets, we think of neat spheres floating directly in front of their star, which acts as a giant spotlight. From our vantage point, they would look more like two perfect two dimensional circles than spheres, though. But nature is almost never so cl

Private companies are getting better and better at launching more and more mass into space with larger and larger rockets. But, there is still a major constraint on the size of objects we can get into orbit - fairing size. This places physical constraints on the overall shape of

When picturing a star, typically people think of giant balls of burning gas in the sky that emit enough light they are hard to miss. Planets, on the other hand, come in one of two general categories - rocky worlds like Earth or gas giants similar to Jupiter. But there is a third

It may not be as obvious, but just like Earth, Mars has seasons. And every day of every summer, an 1,800 kilometer long thin white cloud appears to the west of Arsia Mons, a 20 kilometer high extinct shield volcano. At least for a few hours, before it dissipates until it reappear
