For the second time in a few weeks, we’re writing about research into the temperature gap between the Sun’s surface and its corona. More and more data from various missions continue to feed this wave of discovery. A new paper by Katariina Nykyri of Embry-Riddle, recently publishe

In propulsion system design, engineers have long faced a trade-off between solid and liquid rocket fuels. Each has advantages and disadvantages, and in an effort to try to min/max the efficacy of different types of fuel, researchers have long placed an emphasis on a hybrid betwee

We typically think of the Moon as a static, floating object that has remained the same for basically its entire lifetime, with an occasional asteroid impact serving as an exception. That understanding is grounded in physics - the Moon should have cooled rapidly after forming when

Targets of opportunity sometimes happen in astronomy, and we got a major one when the third interstellar object, 3I/ATLAS, was discovered in July 2025. And it just so happens that in the intervening years between the last known interstellar visitor (2I/Borisov in 2019), we got a

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
