MEGATRON is a good guy!?! Well, at least to cosmologists who are using this simulation to transform our understanding of the universe's first stars.

Astronomers have caught a white dwarf in a rare stage of its evolution as it orbits a "cosmic lighthouse" in the form of a rapidly spinning neutron star pulsar.

Scientists have discovered how jets launched by supermassive black holes can determine how their host galaxies "die."

"We clearly see both planets shaping their environment. Now there is an image of them!"

"We are seeing an extremely overfed black hole wrapped in its own fuel."

Rogue black holes that break away from their cosmic homes may carry with them the histories of the galaxies they may eventually escape.

The JUICE spacecraft returned to Earth on Sept. 28 for a brief visit to pick up a gravity assist to continue its voyage to Jupiter.

Using the James Webb Space Telescope, astronomers have discovered that just 500 million years after the Big Bang, galaxies were already pumping heavy elements into the infant universe.

Astronomers have discovered the first microblazar in the Milky Way, a black hole-powered particle accelerator that is blasting near-light-speed plasma jets at Earth.

Black holes come in a vast array of sizes, from many times the mass of the sun, up to billions of times the size of our star, but the "burps" they emit when feeding seem to be remarkably similar.

Using the X-ray spacecraft XRISM, astronomers have observed stellar winds from a hypermassive star feeding a neutron star.

New research has found that an exoplanet has a real rebellious streak, defying its star and scientists' expectations.

Using the Large Hadron Collider, the world's most powerful particle accelerator, scientists are on the hunt for quantum black holes smaller than atoms.

Scientists have created a video reconstruction of the high-energy jets of a blazar, a supermassive black hole blasting plasma straight at Earth.

Astronomers have studied nine local galaxies to discover how shock waves from the galaxies' central supermassive black holes sculpt star formation.

Sakurai's Object has entered a new stage of its evolution with the "born again" star shedding material in a powerful stellar wind extending over a region similar in size to our solar system.

To solve the mystery of strange "Little Red Dot" objects spotted by the James Webb Space Telescope, astronomers have looked at the bigger picture, studying their host galaxies.

The discovery of 50 "ghost" galaxies located up to 100 million light-years away may solve an astronomy puzzle.

Some vampire white dwarfs that feed on companion stars can transform into neutron stars, but like a cosmic Goldilocks, conditions must be "just right" for this extreme makeover.

Using the James Webb Space Telescope, astronomers have discovered that the ring system of the tiny solar system body is even more interesting than they knew.

The sun may have swallowed a super-Earth planet in its early history, and our star may still be hiding the evidence, new research suggests.

A catalog of almost 3,000 white dwarfs that exploded as type Ia supernovas after overfeeding on companion stars indicates that dark energy is changing over time.

Wrinkles on the surface of Mercury have revealed that the closest planet to the sun is shrinking faster than scientists thought.

Though their origins may be shrouded in mystery, fast radio bursts could be used to probe some of the universe's biggest puzzles, including the nature of dark matter and dark energy.
