Using the eROSITA space telescope, MPE researchers have successfully isolated the X-ray glow from our Solar System, revealing its impact on the soft X-ray sky. The findings, published in Science, underscore the importance of considering Solar System processes when analyzing X-ray data and highlight eROSITA’s role in advancing not only astrophysics but also heliophysics.
Water is critical to life because cells need liquid to function. That's why scientists focus on finding and studying exoplanets in habitable zones. But even if they're in habitable zones, exoplanets need lots of water to support their carbon cycles. So without water, exoplanets become inhospitable greenhouse planets, regardless if they're in habitable zones or not.
New missions mean new capabilities - and one particularly interesting new mission is finally up and running. Data is starting to come in from SPHEREx, the medium-class surveyor that is mapping the entire sky every six months. A paper based on some of that early data was recently published in The Astrophysical Journal, mapping ice and compounds called Polycyclic Aromatic Hydrocarbons (PAHs) throughout some interesting regions of our Milky Way.
Rubin’s largest asteroid haul yet, gathered before the Legacy Survey of Space and Time even begins, is just the “tip of the iceberg”
Cherenkov radiation isn't just a beautiful phenomenon. It turns up in nuclear reactors, in the upper atmosphere, in gamma ray telescopes on three continents, in a cubic kilometer of Antarctic ice, and in hospital imaging suites. Here's what a light boom is actually good for.
Using lunar regolith simulant, a team of researchers demonstrated that "immature" regolith similar to what is expected around the Moon's southern polar region is suitable for rovers to drive on.
We have the crowd. We have the star. Now it's time to put them together. Here's exactly what happens — and why — when a charged particle outruns the local speed of light in a material. Also: why it's always blue.
