Making Waves on the Sun
Sinuous, undulating waves in the Earth’s atmosphere play a large role in driving the weather patterns on our planet. Is this also happening on the Sun?
ASKAP Finds a Real-Time Radio Burst, but No Glow
ASKAP is on the hunt for emission before and after a fast radio burst — which may prove key to unraveling the mystery of these explosions’ origins.
Climate Stabilization on Distant Worlds
Scientists explore whether a world covered in water can keep its climate as stable long-term as an Earth-like, continental world can.
Seeing Cepheids in the X-Ray
Unexpected X-ray emission has been observed in some variable stars when they’re at their largest size. What could be the cause?
Eccentricity, Spin, and the Origins of Colliding Black Holes
The dramatic collision of two enormous black holes has provided new clues pointing to how this binary originally formed.
A Distant Quasar as a Cosmic Clock
Hungry supermassive black holes in the distant cosmos can help us understand what happened shortly after our universe lit up with its first stars and galaxies.
Checking the Speed of Spirals
Gravity or a planetary companion? Recent work uses speed measurements to determine what’s driving the spiral arms in one protoplanetary disk.
A Deep Look at Distant Galaxies with ALMA
We’ve seen what the powerful ALMA observatory can do within our own galaxy — but what can it tell us about distant galaxies across our universe?
Casting Doubt on a Nearby Black Hole
Scientists recently announced the discovery of the nearest black hole to Earth — but there may be a different explanation for this stellar puzzle.
