The universe should be packed with tiny galaxies — so where are they?
There may not be as nearly as many small galaxies in the early universe as astronomers predict there should be, which has big implications for the story of how our universe grew up.
Watch Crew-11 astronauts undock in 1st-ever medical evacuation from the International Space Station today
SpaceX's Crew-11 astronauts will leave the International Space Station today (Jan. 14) in the first-ever medical evacuation from the orbiting lab, and you can watch it live.
Solar and Lunar Eclipses in 2026
This year offers an interesting mix of celestial coverups: a total solar eclipse viewable from Spain and two deep lunar
eclipses (one total, one not quite) visible across North America. The fourth, an annular solar eclipse, will be confined to the bottom of the world.

SpaceX aims to launch a Falcon 9 rocket from Cape Canaveral Space Force Station on Wednesday afternoon, but faces difficult weather.
The Surprising Heat of Early Clusters
Galaxy clusters aren’t supposed to be scorching hot when they’re young. Like infants, they should need time to mature before developing their full characteristics. Astronomers using the Atacama Large Millimetre/submillimetre Array have just discovered that nature doesn’t always follow the same script.
How Black Holes Slowly Starve Galaxies
Galaxies don’t always die dramatically. Sometimes they fade away, slowly strangled by the very black holes at their hearts. Astronomers using the James Webb Space Telescope and the Atacama Large Millimetre Array have caught one such death in progress, revealing a surprisingly subtle method of galactic murder.
When Baby Stars Throw Tantrums
Newborn stars aren’t gentle. They blast ionised gas into space, carving luminous paths through the darkness. NASA’s Hubble Space Telescope has just captured fresh images of one of these stellar outbursts, showing bright ribbons of pink and green gas stretching across 32 light years of space.
U.S. Space Force switches rockets for upcoming GPS satellite launch

The next Global Positioning System satellite is switching from a United Launch Alliance Vulcan rocket to a SpaceX Falcon 9, a spokesperson for the U.S. Space Force’s Space Systems Command System Delta 80 said Tuesday.
The US really wants a nuclear reactor on the moon by 2030. 'Achieving this future requires harnessing nuclear power,' NASA chief says
NASA and the U.S. Department of Energy have firmed up their commitment to develop a nuclear reactor for use on the surface of the moon by 2030.
What time is SpaceX Crew-11's medical evacuation from the ISS on Jan. 14?
The four astronauts of SpaceX's Crew-11 mission will leave the International Space Station on Jan. 14, in the first-ever medical evacuation from the orbital lab. Here are the details.
Two New CubeSats to Monitor Nearby Stars and Distant Black Holes
Two new smallsat missions, named SPARCS and BlackCAT, promise to examine stellar flares and explosions in the early universe.
Young Stellar Objects Are Prominent In A New Hubble Image
NGC 1333 is a reflection nebula in the Perseus Molecular Cloud. The cloud is relatively nearby in astronomical terms, only about 1000 light-years away. The nebula is a very active star-forming region, and since it's so close, it's very well-studied. Most of the cloud is basically invisible, but NGC 1333 is one of two visible structures.

'It felt really warm and welcoming. It was a lovely atmosphere the whole time.'
Siwarha's Wake Gives it Away at Betelgeuse
Betelgeuse is the star that everybody can't wait to see blow up, preferably sooner than later. That's because it's a red supergiant on the verge of becoming a supernova and there hasn't been one explode this close in recorded human history. It's been changing its brightness and showing strange surface behavior, which is why astronomers track its activity closely. Are these changes due to its aging process? Do they mean it's about to blow up? Probably not.
'Death by a thousand cuts': James Webb Space Telescope figures out how black hole murdered Pablo's Galaxy
"It points to a slow starvation rather than a single dramatic death blow."
New Evidence That An Ancient Martian Ocean Covered Half The Planet
Bit by bit, scientists are piecing together Mars' climate history. Thanks to orbiters armed with powerful cameras and rovers carrying suites of scientific instruments, the red planet's history is becoming clearer year-by-year. In the past decade or so, evidence of Mars' ancient habitability is becoming more and more convincing.
Viruses may be more powerful in the International Space Station's microgravity environment
"Microgravity pushed evolution into corners of the phage we still don't fully understand"
Astronomers watch 2 supermassive black holes caught in a twisted dance with never-before-seen jet behavior
"This result shows that the Event Horizon Telescope is not only useful for producing spectacular images, but can also be used to understand the physics that govern black hole jets."
This stunning Orion Nebula photo will make you want to grab a telescope this week
The Orion Nebula is the closest large star-forming region, located within the Milky Way just 1,500 light-years from Earth.
