The discovery made by a large research team challenges the existing models of the universe.

Astronomers have identified what appears to be an unusually distant candidate “jellyfish” galaxy, a strange object trailing a one-sided tail of newborn stars that appears consistent with ram-pressure ...

Scientists traced star-forming gas clouds in a nearby lenticular galaxy, NGC 1387, offering new insight into early-type ...

The space between galaxies is not empty. In a new map of the early universe, those “blank” stretches take on a faint, hydrogen-blue glow that had mostly escaped surveys until now.

In a Universe that was only 700 million years old, long before Earth even formed, something unexpected happened. A massive galaxy stopped forming stars and went silent. This type of galaxy, called ...

Dozens of dwarf galaxies swarming around the Andromeda Galaxy like bees have been caught on camera by the Hubble Space Telescope, which took more than a thousand orbits of the Earth to take enough ...

The red shade shows the atomic hydrogen gas content of the galaxy, overlaid on the optical image. The atomic gas that is outside the white circle does not contribute significantly to the formation of ...

Astronomers have uncovered a hidden population of dusty galaxies that formed just one billion years after the Big Bang, offering a new glimpse into the universe’s formative years. An international ...

Add Yahoo as a preferred source to see more of our stories on Google. There could be many more satellite galaxies orbiting the Milky Way than previously thought or observed, according to astronomers.

The universe doesn’t come with an instruction manual — but if it did, University of Missouri Assistant Professor Charles Steinhardt suspects a few pages are missing. Either the universe has been ...
