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

"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 photo was snapped by Jessica Meir, who took part in the first all-female spacewalk last month.

Researchers in China found a star 15,000 light years away orbiting a "dark companion" that defies theories of stellar evolution.

"It's humbling to realize how small Earth is next to this visitor from another solar system," said Pieter van Dokkum from Yale University.

"Up until now, such a concentration of three supermassive black holes had never been discovered in the universe," Peter Weilbacher, from the Leibniz Institute for Astrophysics Potsdam, said.

Hibernation technology may enable mission designers to reduce spacecraft mass by around a third.

A typical gamma ray burst lasting seconds or minutes produces about the same energy as our sun does over the course of its entire multi-billion-year lifecycle.

The center of our galaxy is located around 26,500 light-years away from Earth.

Traces of extraterrestrial sugars on meteorites add more weight to the hypothesis that a meteor blitz on ancient Earth may have kick-started life by providing the necessary building blocks.

Most years the Alpha Monocerotids produce a modest display with just a handful of meteors.

Solar storms found to "profoundly modify" the foreshock—the region that extends beyond the magnetic field.

Two of Neptune's inner moons are locked together in a type of orbit that has not been seen before. This allows them to cross paths without coming into contact, researchers say.

The latest findings could have important implications for our understanding of how massive stars form.

"'Are we alone?' is one of the biggest unanswered questions," said study first author Howard Chen.

This celestial event only takes place around 13 times a century.

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

Mercury transits take place only around 13 times a century.

Each year, the Taurids peak between the final week of October and first week of November.

AM 2026-424 is the latest creepy cosmic image to be released ahead of Halloween.

This has not stopped physicists attempting to work out how you would spot one if they did—because while there is no proof they do exist, they are at least theoretically possible.

The space rock could measure up to 3,248 feet in diameter.

Human's evolved through a series of highly unlikely events—so finding another intelligence like us would be like winning the lottery many times over.

The teenager sat down with Stylist Magazine to discuss what life would be like in space, from the food to the toilet arrangement —and the prospect of being the very first person to touch foot on Mars.

This is the first time in over fifty years of space exploration that two women will space-walk at the same time.

The comet is only the second confirmed interstellar object to have passed through the solar system.

The Exploration Extravehicular Mobility Unit builds on the designs of spacesuits currently used by astronauts when they conduct spacewalks outside the International Space Station.

An astrophysicist told Newsweek the walk "represents years of dedication, study, hard work, and pushing limits and that is truly inspirational."

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

Originally scheduled for March, the space walk was scrapped when ground control realized there were not enough medium-sized spacesuits for both female astronauts.
