Reigniting a dead star
Aug 30, 2018 (SPX)
During such violent "tidal disruption events" (TDEs), the object being disrupted is simultaneously stretched and compressed in opposing directions. If the objec...
Stellar 'swarms' help astronomers understand the evolution of stars
Aug 30, 2018 (SPX)
"Like a swarm of birds flying together in the sky, the common velocities of stars in an association tell us that us that they are related," Gagne explained. "Th...
Astronomers reveal new details about 'monster' star-forming galaxies
Aug 30, 2018 (SPX)
So-called "monster galaxies" or extreme starburst galaxies are thought to be ancestors of massive galaxies like the Milky Way in today's universe, so these find...
