Scientists have mapped the Alfvén surface, the ‘point of no return’ where solar wind escapes the sun's grasp. Using data from 20 maps, confirmed by NASA's Parker Solar Probe, this dynamic boundary changes with solar activity, enhancing space weather predictions and offering insights into the behavior of other stars.
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.
