TOI-561 b, an ultra-hot super-Earth with an unusually low density, this infographic reveals an unexpectedly cooler temperature of 3,200°F, likely due to a thick, volatile-rich atmosphere. A magma ocean-atmosphere cycle may create an equilibrium, making the planet akin to a "wet lava ball."
We thought Betelgeuse was dying alone. New evidence reveals a secret partner, "Siwarha," pushing the red giant toward its explosive fate.
Betelgeuse has been acting strange—dimming, brightening, and pulsing. While some of this is due to aging, a 6-year cycle stood out.
For 25 years, the ISS has been a factory for the impossible. From cancer research to space farming, discover how microgravity is changing life on Earth.
The Challenge: To design drugs for diseases like cancer or Alzheimer's, scientists need to see the exact shape of the proteins involved. On Earth, gravity crushes these proteins as they grow, creating small, messy crystals.
From the longest jet ever seen to the magnetic heart of a white dwarf, new images reveal the violent and beautiful mechanics of star formation and death.
The Discovery: Hubble has imaged HH 80/81, a pair of glowing shockwaves created by a jet of gas blasting across space.
