The observatory is expected to map around 100,000 galaxy clusters—the largest known gravitationally bound structures in the universe—and three million supermassive black holes.

Astronomers have measured the spin rate of five, distant supermassive black holes for a study published in the Astrophysical Journal.

The probe will use gravity like a slingshot on its seven-year voyage to Mercury.

The discovery could help unlock the secrets of the formation of the universe.

The latest findings shed new light on supernova explosions and the late stages of stellar evolution.

Scientists think that at the heart of nearly every galaxy lies a supermassive black hole (SMBH) with immense gravity.

The jets could provide a link between neutron star mergers and gamma ray bursts—the brightest events ever observed.

Is a mysterious planet lurking at the edge of our solar system?

The searing hot ball of gas at the heart of our planetary neighborhood is home to almost all the mass of the solar system—but it's getting lighter all the time.

Our galaxy has "died" once before and we are now in its second life, according to a new hypothesis.

We might need new physics to know, and the result could be "a showstopping change of our picture of the cosmos."

Who is Georges Lemaître and what were his most important ideas?

The finding shines new light on our understanding of the cosmos.

This is the first time astronomers have directly imaged the brutal phenomenon.

If proven correct, the theory could revolutionize our understanding of the cosmos.

The event horizon is the point of no return beyond which nothing, not even light, can escape the immense gravitational pull of the black hole.

You can help astrophysicists keep track of unidentified supernovas in the universe, and be recognized as a co-discoverer.

Only a few such emissions have ever been observed.

In 2016, scientists from the California Institute of Technology found evidence to suggest that a planet larger than Earth could be hiding beyond the orbit of Pluto, out in the furthest reaches of the Solar System.

The era of big data is revolutionizing how astronomical discoveries are made.

The existence of multiple universes is hotly debated among scientists.

Our sun will die in about 10 billion years' time.

Scientists discovered large quantities of the foul gas in the cloud tops of the planet

The black holes surround the supermassive black hole at the center of the Milky Way.

"It's not Swiss watch precision," researchers say.

Light from the jets can outshine entire galaxies.

When massive stars come to the end of their life cycles, they self-destruct in a cataclysmic final explosion.

More than half of these "ultramassive" black holes have a mass 10 billion times greater than the Sun.

Dark matter could make up around 80 percent of the mass in the universe.

The astrophysicist most recently chimed in about "Titanic." Is he veering away from his strictly science-based reviews?
