The X-Ray Imaging and Spectroscopy Mission (XRISM), a joint mission between the Japanese Aerospace Exploration Agency (JAXA) ...

When astronomers look deep into the early universe, the expectation is simple. You should see young galaxies still assembling ...

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

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 uncovered a gargantuan black hole that appears to sit almost alone in space, with hardly any stars around it ...

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 ...

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 ...

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

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 ...
