Using the James Webb Space Telescope, astronomers have peered into galaxies that existed at cosmic noon to hunt ravenously feeding black holes and bursts of starbirth.

Using the James Webb Space Telescope, astronomers have discovered "smoking gun" evidence of a hidden feeding supermassive black hole in a distant spiral galaxy.

New research suggests that the largest cosmic structure is even bigger and closer to Earth than we knew. It goes against scientists' models of cosmic evolution.

The most distant and earliest "dead" massive galaxy ever seen shows some galaxies lived fast and died young shortly after the Big Bang.

"The singularity is the most mysterious and problematic part of a black hole. It's where our concepts of space and time literally no longer make sense."

Astronomers have discovered the smallest dwarf galaxy ever seen. It is a mystery how the satellite galaxy of Andromeda survived the blistering conditions of the early universe.

"I think that the simplest explanation of the rotating universe is the universe was born in a rotating black hole."

"The Voyagers have been deep space rock stars since launch, and we want to keep it that way as long as possible!"

"Even the strongest hurricanes in the solar system seem calm in comparison."

"The Phoenix cluster has the largest reservoir of hot, cooling gas of any galaxy cluster."

Was a powerful cosmic explosion seen by the Einstein Probe launched by a supermassive black hole snacking on a star, by a gamma-ray burst, or by something entirely new?

A new form of black hole archeology, linking spin to gas and dust, has revealed that these cosmic titans spin faster than expected.

"This process is like a cosmic CT scan, where we can look through different slices of cosmic history and track how matter clumped together at different epochs."

"Our measurements imply that the supermassive black hole mass is 10% of the stellar mass in the galaxies we studied."

The James Webb Space Telescope has spotted one of the earliest and most distant supernovas, marking the death of a stellar monster 20 times the mass of the sun.

Pluto may have got romantic to capture its largest moon, colliding and engaging in a passionate but icy 10 hour kiss with Charon billions of years ago.

A rare group of aligned, star-birthing dwarf galaxies resemble a cosmic string of pearls.

A "missing link" black hole in Omega Centauri is still missing. What appeared to be an intermediate-mass black hole was a cluster of stellar-mass black holes.

What knocked this black hole over onto its side? It's a cosmic "whodunnit" that NASA scientists using the Hubble and Chandra space telescopes are trying to solve.

The James Webb Space Telescope has caught a napping monster black hole in the early universe. The cosmic giant is slumbering after a massive meal like a reveler on Christmas Day.

Scientists at CERN's ALICE detector are replicating conditions found during the Big Bang, attempting to get to the bottom of how matter came to dominate over antimatter.

An asteroid hitting a neutron star could release enough energy to power humanity for 100 million years, more than enough to explain fast radio bursts.

"We would have loved to find that Venus was once a planet much closer to our own, so it’s kind of sad in a way to find out that it wasn't."

"Even years after the Arecibo Observatory's collapse, its data continues to unlock critical information that can advance our understanding of the galaxy."
