Space Weather Can Dramatically Alter a Planet's Fate
We tend to think of habitability in terms of individual planets and their potential to host life. But barring outliers like rogue planets with internal heating or icy moons with subsurface oceans created by tidal heating, it's exoplanet/star relationships that generate habitability, not individual planets. New research emphasizes that fact.
Hubble Telescope sees wandering black hole slurping up stellar spaghetti
Astronomers have caught a black hole far from the center of its galaxy ripping a star to shreds — offering for the first time evidence of a rogue supermassive black hole in action.
The US isn't prepared for a big solar storm, exercise finds
A first-of a-kind space weather "tabletop" exercise has revealed major weaknesses in America's preparedness for major solar storms.
Best solar telescopes 2025: Safely observe sun spots and solar eclipses
The best solar telescopes suitable for the next solar eclipse.
See the world's largest iceberg stranded in the South Atlantic (satellite photo)
A new image from Europe's Copernicus Sentinel-3 satellite shows the huge Antarctic iceberg A-23A stuck 45 miles (73 kilometers) off the coast of South Georgia Island.
Watch the moon and bright star Spica meet in a celestial dance on May 9
I think we know who's supplying the c(r)atering for this dance party.
ZWO Seestar S30 all-in-one smart telescope review
Small but mighty, the ZWO Seestar S30 is an affordable, portable instrument that's great for observing and imaging deep-sky targets.
Cosmic imposter bathes distant nebula in fiery red glow: 'This star should not be here'
The brilliant blue-white star lighting up the red nebula Sh2-46 hints at a dynamic and possibly fleeting encounter that could reshape the nebula's appearance over time.
Earth from Space: Northwest Sardinia, Italy

A failed Soviet Venus probe is expected to fall to Earth today, but when and where? Here's what we know
The Soviet Venus probe Kosmos 482 is expected to fall to Earth on May 10, but exactly when and where remains unknown.
How Many Rogue Planets are in the Milky Way? The Roman Space Telescope Will Give Us an Answer
Over the past decade or so, astronomers have speculated about the characteristics of rogue planets in the Milky Way Galaxy. These "free-floating" worlds don't orbit stars, but instead roam the spaceways. They're hard to spot with current technology, but the upcoming Nancy Grace Roman Space Telescope (Roman) will be a perfect instrument to find them and give insights into the history and features they may have in common with Solar System worlds.
Quasars Don't Last Long. So How Do They Get So Massive?
One of the unanswered questions in astronomy is just how supermassive black holes grew so big, so quickly. A team of astronomers have tried to answer this question by searching for actively feeding supermassive black holes (aka quasars) as a way to measure how much material material they are actually accumulating. They studied nebulae near the quasars that light up with the quasar is releasing radiation and found that many of the more distant quasars have only been active for a few hundred thousand years, not long enough to grow to the size we see today.
China uses 'gravity slingshot' to rescue pair of wayward moon satellites
After a pair of satellites failed to reach their desired orbit around the moon last year, China used a novel gravity "slingshot" tactic to get the satellites in the correct spot.
A failed Soviet Venus probe is falling to Earth, and an astronomer will attempt to catch it on camera on May 9
The Virtual Telescope Project aims to observe the anticipated reentry of the former Soviet Union's Cosmos 482 spacecraft as it plunges toward Earth during a live webcast on May 9.
What will happen to VIPER? NASA shifts into reverse on canceled moon rover
NASA is no longer asking U.S. companies for proposals to get the ice-hunting VIPER rover to the moon but still hasn't given up on the mission.
This Supermassive Black Hole Chases its Food
Supermassive Black Holes reside at the center of large galaxies, where they dominate their surroundings and sometimes eat stars. When they gobble up a star, they emit a distinctive light flare. This makes it easier for astronomers to pinpoint their location. Astronomers have detected one of these flares offset from a galactic center. Is the black hole shifting its location?
A failed Soviet Venus probe is falling to Earth. Here's what it might look like
Recent sighting of spacecraft and debris burning through the atmosphere during their plummet back to Earth offer some clues as to what the reentry of a failed Soviet Venus lander might look like.
US Space Force test fires thrusters for moon surveillance spacecraft
The U.S. Space Force tested a new propulsion system designed for satellites that will keep tabs on spacecraft and other objects near the moon.
Satellites show 28 US cities are sinking, including NYC and Chicago: 'Infrastructure can be silently compromised'
A new study has found that the 28 most populous cities in the United States — including New York, Chicago, Dallas and Denver — are sinking at rates between two and 10 millimeters (0.08 and 0.4 inches) per year.
