Spinning rugby balls—the rotation of the most massive galaxies
By targeting the most massive galaxies in our universe, astronomers have studied how their stars move. The results are surprising: while half of them spin around their short axis as expected, the other half turn around their ...

Astronomers witness galaxy megamerger
Peering deep into space—an astounding 90 percent of the way across the observable universe—astronomers have witnessed the beginnings of a gargantuan cosmic pileup, the impending collision of 14 young, starbursting galaxies.

Double or nothing—astronomers rethink quasar environment
Using Hyper Suprime-Cam (HSC) mounted on the Subaru Telescope, astronomers have identified nearly 200 "protoclusters," the progenitors of galaxy clusters, in the early universe, about 12 billion years ago, about ten times ...

Black holes from small galaxies might emit gamma rays
As a general rule of thumb, if there is a puzzling phenomenon occurring somewhere deep in outer space, a black hole is often the culprit behind it.

Study of distant galaxies challenges the understanding of how stars form
The most massive galaxies in our neighbourhood formed their stars billions of years ago, early in the history of the universe. At the present day, they produce very few new stars. Astronomers have long believed that is because ...

New SOFIA observations help unravel mysteries of the birth of colossal suns
Astronomers are observing star-forming regions in our galaxy with NASA's flying telescope, the Stratospheric Observatory for Infrared Astronomy, SOFIA, to understand the processes and environments required to create the largest ...

Library of galaxy histories reconstructed from motions of stars
Just as the sun is moving within the Milky Way, all the stars in galaxies are moving, but with very different orbits. Some of the stars have strong rotations, while others may be moving randomly with no clear rotation. Comparing ...

Supermassive black holes control star formation in large galaxies
Young galaxies blaze with bright new stars forming at a rapid rate, but star formation eventually shuts down as a galaxy evolves. A new study, published January 1, 2018, in Nature, shows that the mass of the black hole in ...
