Clues In A Dusty Disk Point The Way To A Potential Exoplanet
Large exoplanets are more easily detected than small ones. It's axiomatic. While large planets block out more starlight during transits, small planets block out much less, letting them hide in the overpowering glare from their stars. To help detect sub-Jupiter mass exoplanets, astronomers search for the effect these planets can have on their surroundings.
The interstellar comet 3I/ATLAS is wrapped in carbon dioxide fog, NASA space telescope reveals
The interstellar visitor appears to have a lot in common with its solar system brethren.
'Invasion' star Shamier Anderson says he's 'out of here' if aliens do actually invade (exclusive)
'The aliens are coming to Earth? I'm going, 'Here’s the bill. Credit or debit? Have a good day.’'
SpaceX Dragon cargo capsule boosts ISS higher above Earth in key test
SpaceX’s Dragon capsule demonstrated its ability to boost the ISS on Sept. 3, pushing the orbiting lab slightly higher above Earth.
Most solar eclipse maps have a major flaw. Here's how to ensure you're really in the path of totality
Solar eclipse maps show crisp lines for the path of totality, but in reality, the edges of the path are fuzzy, jagged and sometimes wrong by hundreds of meters or more

Bright Stars in the Night Sky
Welcome, stargazers, to a journey through the twinkling wonders above! The night sky holds countless mysteries and breathtaking sights, and today we'll explore some of its brightest stars.
There's nothing original about 'Strange New Worlds' latest episode, 'Terrarium', but it's classic 'Star Trek'
We've seen it all before, but some sci-fi clichés just work.
Gravitational waves reveal 'stellar graveyard' packed with neutron star and black hole mergers
Astronomers have doubled the number of black hole and neutron star mergers detected via gravitational waves in a "stellar graveyard," as well as "hearing" the heaviest black hole binary yet.
Galileo ‘daughter mission’ name revealed: Celeste
Following the announcement of the upcoming launch of LEO-PNT’s first satellites, ESA has now unveiled the name of the mission. Celeste, as it has been officially designated, will test the potential of a new, low Earth orbit layer of satellites to enhance Galileo’s resilience and complement its capabilities.
Where to see the blood moon lunar eclipse Sept. 7–8
The September 2025 total lunar eclipse will bring a blood-red moon to skies across Asia, Australia, Africa and Europe — if you know where to look.
Butterfly Star flaps its rainbow wings | Space photo of the day for Sept. 4, 2025
This young star is surrounded by a protoplanetary disk, separating the "wings" of the butterfly.
BlueDOGs Might Evolve From Little Red Dots
One of the most difficult parts of astronomy is understanding how time affects it. The farther away you look in the universe, the farther back you look in time. One way this complicates things is how objects might change over time. For example, a supermassive black hole at the center of a galaxy in the early universe might appear one way to our modern telescopes, but the same supermassive black hole might appear completely differently a few billion years later. Understanding the connection between the two objects would be difficult to say the least, but a new prerint paper on arXiv from researchers at the University of Science and Technology in South Korea describes one potential parallel, between the recently discovered “Little Red Dots” of the early universe and “BlueDOGs” of the slightly later universe.
US in real danger of losing the moon race to China, experts tell Senate
A Senate Commerce Committee hearing sounded the alarm over the U.S.-China moon race, emphasizing American dominance off Earth as the backdrop for NASA’s next funding authorization.
Second MTG-Imager satellite passes thermal vacuum test
The second of the Meteosat Third Generation Imagers, MTG-I2, has passed some important milestones in the cleanroom facilities at Thales Alenia Space in Cannes, southern France.
Watch NASA's Artemis 2 moon astronauts take on the viral 'Bobby and Pete' fitness challenge (video)
The four Artemis 2 moon astronauts passed the "Bobby and Pete" fitness challenge recently, performing 100 pushups and 50 pull-ups in less than 10 minutes.
Astronomers Use a Double-Lensing Technique to Study a Supermassive Black Hole
In astronomy, some of the most profound discoveries happen by accident. As the saying goes, "The most exciting phrase in science is not 'eureka!' but 'that's funny.'" This was certainly the case with Matus Rybak - a postdoctoral researcher at Leiden University - and his colleagues were observing RXJ1131-1231, a quasar located 6 billion light-years away in the constellation Crater. This active galactic nucleus (AGN) is a favorite among astronomers because of the supermassive black hole (SMBH) at its center and the fact that there is an intervening galaxy between it and Earth.
Ionic Liquids Could Form Naturally And Replace Water As A Biological Solvent
Water is key to life as we know it. But that doesn’t mean its key to life everywhere. Despite the fact that the ability to house liquid water is one of the key characteristics we look for in potentially habitable exoplanets, there is nothing written in stone about the fact that life has to use water as a solvent as opposed to other liquid options. A new paper from researchers at MIT, including those who are developing missions to look for life on Venus, shows there might be an alternative - ionic liquids that can form and stay stable in really harsh conditions.
The Butterfly Star And Its Planet-Forming Disk
The Taurus star-forming region is only a few hundred light-years away, and it may be the nearest star formation region to Earth. It's a stellar nursery with hundreds of young stars, and attracts a lot of astronomers' attention. One of the young stars in Taurus is named IRAS 04302. IRAS 04302 is sometimes called the "Butterfly Star" because of its appearance when viewed edge-on.
