Astronomers Map Vast Void in our Cosmic Neighborhood

Map showing the local void

An astronomer from the University of Hawaii Institute for Astronomy and an international team published a new study that reveals more of the vast cosmic structure surrounding our Milky Way galaxy.

The universe is a tapestry of galaxy congregations and vast voids...

Hubble Uncovers a Galaxy Pair coming in from the Wilderness

NASA's Hubble Space Telescope has captured the glow of new stars in these small, ancient galaxies, called Pisces A and Pisces B. The dwarf galaxies have lived in isolation for billions of years and are just now beginning to make stars. Credit: NASA, ESA, and E. Tollerud (STScI)

Hubble has uncovered 2 tiny dwarf galaxies that have wandered from a vast cosmic wilderness into a nearby “big city” packed with galaxies. After being quiescent for billions of years, they are ready to party by starting a firestorm of star birth. “These Hubble images may be snapshots of what present-day dwarf galaxies may have been like at earlier epochs,” said Erik Tollerud of the Space Telescope Science Institute in Baltimore, Maryland...
