Illustration of the exoplanet WASP-107b, a 'super-puff' planet with a size similar to Jupiter but only one-tenth its mass. Located 210 light-years away, it orbits close to its star, likely having migrated from a distant orbit. The illustration highlights the significant helium escape, forming a gas tail extending ten times the planet's radius. The atmosphere contains water, carbon monoxide, carbon dioxide, and ammonia, but no methane. The James Webb Space Telescope plays a crucial role in observing these phenomena.
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.
