Hubble images of elliptical galaxy yield surprising discoveries

Recent Hubble images of Centaurus A, the elliptical galaxy closest to the Milky Way, reveal it is surrounded by a halo of stars much larger than previously thought and that stars within that halo are surprisingly metal-rich...

Astronomers construct most detailed galaxy cluster mass map yet

Observations from Hubble’s Frontier Fields observing program has allowed astronomers to map the mass distribution of a galaxy cluster with unmatched detail...

   
Dwarf galaxies discovered ‘dancing’ around their giant counterparts
Dwarf galaxies discovered ‘dancing’ around their giant counterparts

It seems that even galaxies have a sense of rhythm to them. Scientists have uncovered that they "dance" around giant galaxies in a disc-like pattern. This discovery differs from the conventional model about their movements, one which held that the smaller galaxies swarmed around the larger ones...

Scientists: Cosmic tug of war in the stars requires more investigation

According to astronomers, a string of stars -- aligned like a necklace of blue pearls and found along two elliptical galaxies -- could be the result of a galactic merger...

Yale astronomers have found seven dwarf galaxies using a new kind of telescope constructed by joining together telephoto lenses...

   
Galaxies unite to create ‘beads on a string’ phenomenon
Galaxies unite to create ‘beads on a string’ phenomenon

Two galaxies have intertwined to create a bright string of stars, stretching as far as the length of our Milky Way galaxy. Astronomers claim the stars appear as gems shining bright on a necklace, a sight that was initially thought of as an illusion...

   
Dark matter detected in the form of X-rays from far-off galaxies
Dark matter detected in the form of X-rays from far-off galaxies

NASA scientists have detected unidentified particles emitting from a galaxy 250 million light-years away. The particles were received as X-ray signals which demonstrate theorized behaviors of dark matter- a substance which comprises 85 percent of all matter in the entire universe...
