It has long puzzled scientists that there were enormously massive galaxies that were already old and no longer forming new stars in the very early universe, approx. 3 billion years after the Big Bang.
By observing a high-speed component of a massive galaxy cluster, Caltech/JPL scientists and collaborators have detected for the first time in an individual object the kinetic Sunyaev-Zel'dovich effect, a change in the cosmic microwave background caused by its interaction with massive moving objects.
Qualcomm's Snapdragon 800 SoC is probably one of the most impressive high-end ARM-based processors.
The first galaxies were small, then eventually merged together to form the behemoths we see in the present universe.
Astronomers have discovered the two largest black holes ever - 10 billion times as massive as our own sun - which look set to consume everything within a region five times the size of our solar system.
The first stars in the universe may have spun at over a million miles per hour, astronomers at the Leibniz-Institut für Astrophysik Potsdam (AIP) and the Instituto Nazionale di Astrofisica (INAF) say.
Astronomers have been astonished to find a supermassive black hole in the center of a tiny low-mass galaxy, suggesting that such black holes can form before their host galaxies.
As game publishers look to other forms of in-game revenue, Microsoft has closed the doors on a company it acquired to bring dynamic advertisements in video games.
