Astronomers have discovered a remarkable triple star system in which two Sun like stars orbit each other every 4.75 days, while a giant star, ten times the size of our Sun circles the pair every 412 days. All three orbit in almost exactly the same plane, and because we view that plane edge on from Earth, the stars eclipse each other in a distinctive pattern that allows all three to be measured simultaneously. The giant is slowly swelling and will eventually overflow its gravitational boundary, triggering a dramatic mass transfer event that could reshape or even destroy the system.

In August 2025, a NASA spacecraft detected a solar radio burst that refused to stop lasting 19 days, nearly four times longer than any previously recorded. A team of researchers used data from four spacecraft spread across the inner Solar System to track the event and pinpoint its source to a magnetic structure called a helmet streamer, likely supercharged by a series of powerful solar eruptions.

Scientists have captured one of the most detailed observations ever of a failed solar eruption, a powerful blast from the Sun that built into what should have been a billion tonne plasma ejection, then stalled and collapsed back to the surface. Using data from five spacecraft simultaneously, the team identified a double magnetic process that strangled the eruption from both above and below.

In the heirarchy of black holes, intermediate mass black holes (IMBH) lie in between stellar mass black holes and supermassive black holes. But the problem is that we’ve never found one. There have been hints, but nothing conclusive. Could gravitational microlensing of Fast Radio Bursts help find them?

Our Sun is a loner. It lacks a stellar companion hurtling through interstellar space with it. But we’ve known for a long time that’s actually relatively rare – most stars have at least one gravitationally bound partner. Understanding how exactly those stars are related to each other is critical for observational campaigns – especially for those of exoplanets. So a new paper from researchers at the University of Madrid that categorizes almost every star within ten light years into companion categories is a welcome addition to the literature on the subject, and could be used to inform the next round of planet habitable planet hunting satellites.

We’ve been reporting a lot lately on the negative impacts of satellite constellations. And unfortunately it’s time for another article about a paper pointing out the potential hazards of them. This one, by lead author Conner Barker of University College London, focuses on the pollution caused by rocket launches – and admittedly contains some good news, but also a cautionary tale that policy makers should be aware of.

In a stellar flyby, a star approaches our Solar System close enough to create gravitational mayhem. The last one was 70,000 years ago. There are more in the future, and it’s possible that they could disrupt comets from the Oort Cloud and send them into the inner Solar System, with the risk of catastrophic impact.

SpaceX will follow up a picturesque Falcon 9 launch from Cape Canaveral Monday morning with another from Vandenberg Space Force Base Tuesday morning. The Starlink 17-37 mission, which was originally scheduled to launch on May 9, faced several launch delays throughout the month of May. The flight went through two previous booster assignments (B1097 and B1103) before Continue ReadingLive coverage: SpaceX to launch 24 Starlink satellites on Falcon 9 rocket from Vandenberg SFB→
