Scientists have detected gravitational waves—ripples in the fabric of spacetime—from a collision between black holes and neutron stars for the first time.

The computer simulation, based on modeling technology called STARFORGE, shows how a huge gas cloud floating in space eventually births stars over time

The black hole, located inside the Milky Way galaxy, is also among the smallest known to science.

Scientists spotted the star being ripped apart by a black hole millions of light-years from Earth.

Supernovae are cataclysmic explosions that occur during the last evolutionary stages in the life of massive stars.

Sunspots are dark spots that temporarily appear on the solar surface.

Eryurt is celebrated on the 51st anniversary of the Apollo 11 moon landing, as her research allowed NASA to develop technology that was crucial to the 1969 mission.

"These images are closest images ever taken of the sun—and we have just started our long journey through the inner solar system," said Daniel Müller from the European Space Agency.

"This all-sky image completely changes the way we look at the energetic universe," said researcher Peter Predehl.

Researchers say determining intelligence across the galaxy could give clues to our own fate.

The finding could shed light on the long-debated issue of when Saturn's rings and moons formed.

"The flash was so powerful that it lit up the stream like a Christmas tree," said researcher Andrew Fox.

Researchers have long debated the cause of this warping, and several hypotheses have been proposed to explain it.

The hourglass-shaped object, known as CVMP 1, is one of the largest known planetary nebulae.

Scientists previously thought stars like these were not capable of such high-energy eruptions.

Radiation from dying main sequence stars can cause asteroids to spin until they break up, researchers have found.

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

The results could have significant implications for space weather prediction, particle physics experiments on Earth and our understanding of the sun's atmosphere.

"Imagine condensing two-thirds of the Milky Way—which has a stellar mass equivalent to 60 billion suns—into a black hole and you have what we measured," said researcher Roberto Saglia.

The explosion occurred on the surface of a pulsar around 11,000 light-years away.

"I can't believe we are the only living entity in the universe," Didier Queloz said

Black holes are dead stars that, after exploding as supernovae, have so much mass that nothing can hold them together, causing them to collapse into a singularity.

Researchers estimate that the explosion lasted for approximately 300,000 years.

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."

"Simulations and movies like these really help us visualize what Einstein meant when he said that gravity warps the fabric of space and time," the creator of the images said.

A team of astronomers has discovered the "fastest eclipsing white dwarf binary" star system in the known universe.

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.
