Universe

For decades, scientists have been boggled by outstanding questions about the fundamental nature of everything.

Scientists ask amateur astronomers to help seek clues about the origin of water, among other celestial mysteries.

A Finnish artist who turned his camera skyward 25 years ago has completed an unprecedented image of the Milky Way.

The test marks a key milestone in the lead up to the launch on October 31, 2021.

"With the relaunch of Castle Grayskull, we have reimagined one of the most iconic playsets of all time to capture the mystique, love and excitement of the original as the ultimate tribute to fans, new and old alike."

The last ever explosions will be silent fireworks that take place long after everything else in the universe has died, a study has found.

Fast radio bursts were used as "cosmic weigh stations" to find the sparsely distributed matter.

Researchers were looking to see if part of the Standard Model of physics would hold up under extreme conditions.

Scientists say d-star hexaquarks may have formed dark matter after the Big Bang.

Scientists say they have found the first fast radio burst that has a steady repeating cycle.

The AI tool could play a role in studying the nature of dark energy and dark matter, which seems to make up a large amount of the universe but remains an enigma, researchers said.

Mergers with other galaxies may have knocked the black hole in dwarf galaxies off-center, creating "wandering" black holes.

Researchers have observed the faint glow of "gas halos" around galaxies hosting supermassive black holes.

Intriguingly, the Neptune-like planet is is about four times bigger than the star itself.

The galaxy, spotted with ALMA, had been obscured by a huge cloud of dust, making it invisible to other telescopes.

Five years ago scientists proposed the hypothetical existence of a large world tens of millions of miles from the Sun, which has come to be known as "Planet Nine."

"In the search for life beyond our solar system, the most promising planets might not be Earth twins," says geochemist Stephanie Olson.

The snow contained substantial quantities of dust-enriched with iron-60—which isn't naturally produced on our planet.

The latest findings could help to explain some puzzling measurements collected by the Juno spacecraft, which is currently orbiting the planet.

The galaxies formed in the first two billion years after the Big Bang.

These early stars may have blown up in a more violent and asymmetric fashion than previously thought.

This is the "longest, slowest process that has ever been directly observed," said study co-author Ethan Brown.

Marvel's latest Avengers: Endgame posters have inspired a viral Avenge the Fallen meme that is taking over social media.

The collision took place 10 billion years ago, when the universe was just three or four billion years old.

Doom Patrol attempt to help Raven with her powers in new "Titans" photos.

The supernova may indicate the birth of a neutron star binary system, according to a new paper.

Fast radio bursts were recorded during a survey of the sky that began January 2017.

The search is on for an elusive particle that could shine a light on the "dark sector"—the vast majority of the universe that we cannot see.

Computer simulations will help scientists better understand the smallest and densest known stars.

Scientists have used gravitational waves to rule out popular theory explaining one of the universe's mysteries.
