QSO1. It lived just 700 million years after the Big Bang and already had a mass about 50 million times that of the Sun.

Astronomers have obtained the sharpest-ever X-ray spectrum of an iconic active galaxy, providing the most accurate, precise ...

One of the most notable aspects about our planet—if observed from the outside—is that it spins. Earth’s spin defines our days, setting the fundamental rhythm of life on our world. The moon spins, too.

A comprehensive set of simulations by Flatiron Institute astrophysicists and their colleagues revealed that magnetic fields are responsible for creating black holes with masses in a range previously ...

Black holes are not cosmic vacuum cleaners. They are among the universe’s most extreme objects - and come in different sizes.

If a new proposal by physicists bears out, the recent detection of a record-setting neutrino could be the first evidence of elusive Hawking radiation. (Nanowerk News) The last gasp of a primordial ...

The black hole was bigger than expected, and while the answer was hiding in plain sight, it still rewrites what we thought was possible. Reading time 4 minutes When LIGO broke news of an ...

The center of the Milky Way twinkles in microwave radiation, seen in new data obtained by astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile. This study could help ...

Scientists may have finally uncovered the mystery behind ultra-high-energy cosmic rays — the most powerful particles known in the universe. A team from NTNU suggests that colossal winds from ...

What would a human see and feel while falling into a black hole? In this exclusive excerpt of his new book, "Facing Infinity," author and astrophysicist Jonas Enander tells us in terrifying detail.
