How do small galaxies get magnetic fields?
Astronomers showed that small galaxies orbiting larger galaxies become 2 to 8 times more magnetic after nearing their hosts.
Where do deep-space gamma-rays come from?
Researchers found that distant star-forming galaxies can only account for about half of the high-energy radiation from outside the Milky Way…
Galactic clusters impact star formation
Researchers used light emissions to reconstruct the evolution of galaxies that fall into clusters in deep space.
Hot spring rocks could help find life on Mars
NASA researchers found that the shape of rocks near hot springs influences the preservation of chemical fossils that could be detectable on…
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…
