What is matter and dark matter? What kinds of things happen in space? What do we know about the physics in space?
Galactic clusters impact star formation
Researchers used light emissions to reconstruct the evolution of galaxies that fall into clusters in deep space.
The Sun’s coldest regions are warmer than expected
Researchers found that the coldest regions of the Sun’s surface are much hotter than models predicted, likely due to turbulence in its…
How does frost form on Mars?
Astronomers discovered satellite images of morning frost on Mars’ volcanoes. They proposed that the frost is made of water based on…
Scientists find frost on Martian volcanoes
Researchers found frost accumulations on Martian volcanoes that formed from water vapor in the atmosphere.
Scientists date star columns at the center of galaxies
Researchers used data from the Very Large Telescope in Chile to study dense columns of stars at the center of 20 nearby galaxies. They found…
Machine learning helps find other Earths
Astronomers used an algorithm on stars with known exoplanets to identify 44 systems with potential Earth-like planets, 8 of which they…
Is Earth safe from nearby exploding stars?
Scientists used an Earth system model to test how radiation from a nearby supernova would affect life on our planet. They found that the…
Dying stars create new elements
Astrophysicists showed that collapsing white dwarfs can eject enough material to form heavy elements.
Scientists discover a planet-eating star
Astronomers studied light emissions from a star system 2 years after its peak brightness and saw that it had consumed and partially spat out…
