SUNSET: 
Webb and Spitzer Telescopes Explore the Planets That Never Were
Planetesimal wrecks are raging around distant stars. With the Webb and Spitzer Space Telescopes, astronomers are learning what that looks like.
Southern Alberta Star Party (SASP)
We have plenty of room on the field for additional camping and we also have some camp cabins available for rent. In addition, the town of Elkwater (about 1 km away) has a lodge with high-caliber accommodations that can be rented; some even include Jacuzzis. This star party is held annually during the…
Stunning Panorama Reveals Tiniest Brown Dwarfs Yet
The stellar nursery IC 348 is forming lots of stars — and some of the puniest brown dwarfs (aka, “failed stars”) we’ve ever seen.
Join the World in Observing the Moon on September 19th
Disconnect from the digital world for a while — all you have to do is look up.
Once-in-a-Century Impact Made a “Cold Spot” on the Moon
In watching an impact's aftermath, scientists have confirmed that such large blasts shake up and cool wide swaths of the lunar surface.
The Helix Nebula is Hurling Clumps of Gas through Space
The star at the heart of the oft-observed Helix Nebula powered a clumpy wind before it died. Now, new images capture these clumps’ dissolution into the space between stars.
Inouye Solar Telescope Sees the Sun Closer Than Ever
Scientists observing the Sun with the Daniel K. Inouye Solar Telescope have caught a wave-like shape that's never been seen on the Sun's visible surface.
A New Way to Map the Universe's Missing Matter
Brief but powerful flashes of radio waves are aiding astronomers' quest to find and map cosmic gas.
Famous System Has a Third Planet: Beta Pictoris d
Two teams of astronomers independently discovered a third giant gas planet orbiting in the famous Beta Pictoris system.
Euclid Telescope Finds Quasars Within 700 Million Years of the Big Bang
The sharp-eyed and far-seeing Euclid space telescope has picked up 31 early quasars that have evaded detection until now.
Interstellar Comet 3I/ATLAS Has Cold, Ancient Origins
The most recent interstellar visitor was crisscrossing our galaxy for some 10 to 12 billion years before it came near the Sun.
Astronomers Spot Possible Missing Link to Webb’s Little Red Dots
Astronomers may have found the missing link required to understand one of the James Webb Space Telescope’s most puzzling discoveries.

Scientists have unveiled a new dynamic view of our world at night, showing for the first time a night-by-night view of changes in light pollution.
New Astro Images: Saturn, the Crab Nebula, and a Newborn Planet
Striking images from Hubble, Webb, and the Very Large Telescope dive into Saturn's atmosphere, capture the Crab Nebula's expansion, and reveal a newborn planet.
How AI Is Reshaping Astronomy
Artificial intelligence is revolutionizing our world — and how we interpret the heavens above us.
Explore the Worlds of Project Hail Mary
When Andy Weir published Project Hail Mary, he based his novel on two worlds. We explore these planet candidates — and why they probably don’t exist.
Super-Bright Supernovae Are Birth Cries of Magnetars
The disk of gas that spirals onto a newborn magnetar wobbles, creating "bumps" in the brightness of the supernova that accompanied this object's birth.
AI Reveals New Galaxies in James Webb Space Telescope Images
Known as ASTERIS, the AI network removes noise from images to reveal features a full magnitude fainter than before.
Infant Galaxy Clusters Grew Faster Than Expected
Astronomers have discovered three still-growing galaxy clusters in the early universe that point to a faster track of evolution than expected.
What the Helix Nebula Has in Common with a Supernova Remnant
Sculpted gases in the Helix Nebula, revealed in a new Webb image, look like the firework-like tendrils in a distant amateur-discovered supernova remnant — here's why.
