Astronomers have found a baby system that’s just beginning to build planets — and it can tell us about how and where planet formation starts.
Scientists have examined the interstellar invader 3I/ATLAS, finding evidence that it is packed with water that could be older than the solar system.
A Space.com obituary for the ‘Prince of Darkness' Ozzy Osbourne.
The 2024 YR4 asteroid may come close to Earth, but how do experts calculate this potential impact?
Our galaxy will make for a particularly splendid sight on the dark nights surrounding the new moon phase on July 24.
A death-defying star survived destruction by a ravenous supermassive black hole in a tidal disruption event, and came back to let the cosmic titan take another bite!
The Atacama Desert in Chile recently received some snowfall, causing issues for the ALMA (Atacama Large Millimeter/submillimeter Array) telescope.
The next sea-level monitoring satellite, Copernicus Sentinel-6B, has begun its journey from Europe to the Vandenberg Space Force Base in California, where it is scheduled to launch in November. Carefully packed into a climate-controlled container, the satellite is currently crossing the Atlantic Ocean aboard the cargo ship Industrial Dolphin.
NISAR, a joint mission of NASA and ISRO set to launch on July 30, will be able to see shifts in the landscape smaller than a centimeter to give warning of potential natural disasters.

On 15 July 2025, with the splashdown of the Dragon capsule off the coast of California, the Ignis mission ended after a 20-day space journey. ESA project astronaut Sławosz Uznański-Wiśniewski from Poland, during nearly 230 orbits around Earth, completed about 120 hours of telework on the International Space Station and contributed to more than 20 experiments from his orbital office.
With launch slated for August, the first MetOp Second Generation satellite, MetOp-SG-A1, which also carries the Copernicus Sentinel-5 mission, is currently undergoing final preparations for liftoff aboard an Ariane 6 rocket from Europe’s Spaceport in French Guiana.
Astrophysicists don't know if direct-collapse black holes are real. They were hypothesized to explain how the Universe could contain supermassive black holes (SMBH) so early. They don't require a stellar progenitor, nor do they require hierarchical merging. Instead, they collapse due to instability in a gas cloud, much like stars do.
What new exercise methods can be devised for astronauts in space under microgravity conditions? This is what a recent study conducted submitted to the 2025 Technology Collaboration Center’s (TCC) Wearables Workshop and University Challenge hopes to address as a team of Rice University engineering students developed a new type of space exercise harness that could make exercising under microgravity easier and more comfortable.
A SpaceX Falcon 9 rocket launched two of SES's O3b mPOWER communications satellites toward medium-Earth orbit today (July 22), then aced its landing on a ship at sea.
Meteor-watchers will be busy this month and next. Not only are the Southern Delta Aquariids peaking soon, but they get a boost from additional minor showers.
Astronomers have discovered a 200-light-year-wide Giant Molecular Cloud dubbed the Midpoint cloud that seems to be feeding star-building material to the heart of the Milky Way.
Around three decades ago, we weren't certain that other stars had planets orbiting them. Scientists naturally thought there would be, but they had no evidence. Now, not only do we know of more than 6,000 confirmed exoplanets, but we can watch as baby planets take shape around distant stars.
The Moon's thin atmosphere, called an exosphere, has been a puzzle to science for some time. Two main processes were thought to create this wispy gas envelope; tiny meteoroids hitting the surface and solar wind particles bombarding the lunar soil. But new research using Apollo moon samples reveals that the Moon's own surface features provide surprising protection against solar wind erosion.
When a star gets too close to a supermassive black hole (SMBH), the star's fate is sealed. The SMBH's gravity is overwhelming, and as the star is drawn toward the hole, it is stretched out and eventually consumed. These are called tidal disruption events (TDE), and while they're rare, their brilliant light catches astronomers' attention.
The thin crescent moon and Jupiter will be visible to the naked eye for early risers on July 23.
