The iconic supernova blazed with the power of 100 million suns for several months after being discovered close to our galaxy in 1987.
Betelgeuse, a red supergiant, has been getting brighter over the last few months, leading scientists to suggest it may explode sooner than expected.
"When you look up in the sky, you can clearly see a bright, cloud-like shape in the sky which is the core of our own galaxy," Michael Abramyan said.
A viral video of a giant red moon rising over the Alps has garnered hundreds of thousands of views, but is it real?
At 40 light years away from Earth, TRAPPIST-1's four Goldilocks zone planets are one of the prime candidates for finding extra-terrestrial life.
An enormous gamma-ray burst from a dying star was the most powerful recorded, scientists have said.
It lies in the Large Magellanic Cloud, a satellite galaxy that neighbors the Milky Way and orbits a hot, blue star that is almost three times as big.
The announcement could feature an important discovery about our galaxy's supermassive black hole, Sagittarius A*.
By studying a quarter of a million stars before they expanded into red giants, astronomers have revolutionized our picture of how the Milky Way was formed.
The record-breaking beam is emanating from a pulsar—a rapidly rotating, collapsed star with a strong magnetic field—located around 1,600 light-years from Earth.
The bubbles, which extend over 36,000 light-years, are being driven by energetic outflows from its supermassive black hole.
The black hole is stealing material from a companion star, in a process that could show how black holes get a kick from supernova explosions that form them.
Some massive stars travel distances that should take many of their relatively short lifespans to traverse. Astronomers think they now know how this happens.
The discovery of 70 confirmed cosmic orphans not orbiting parent stars is the largest find of freely wandering exoplanets to date.
The weaving of stars around the Milky Way's central black hole shows how it dominates the heart of the galaxy.
New research from the Hubble Space Telescope suggests that our galaxy's central black hole Sagittarius A* belches out jets of material as it swallows surrounding gas clouds.
The discovery of such a massive black hole in a dwarf galaxy could help explain both how galaxies evolve and how dark matter is distributed throughout them.
The 366 exoplanets were found by an algorithm that searched 800 million images of stars taken by NASA's Kepler Space Telescope in its K2 mission.
Scientists are now trying to learn more about the galaxy, named Pisces VII/Triangulum III, which has been described as a significant discovery.
Scientists believe the area, known as the Central Molecular Zone, could shed light on the origins of cosmic rays that bombard Earth.
The duel between the galaxies, 22 million light-years from Earth, resembles a violent encounter in the Milky Way's distant past that could have shaped it.
The possible Saturn-sized planet was detected in the galaxy Messier 51, 28 million light-years from Earth, making it the most distant exoplanet ever found.
The fact that the solar system could be traveling through a highly magnetized filament in space may also explain mysterious rope-like structures in the sky.
The massive cavity in molecular clouds within our galaxy was discovered as scientists studied the first 3D maps of these star-forming regions.
"There are likely more weird ones out there, and we need to think about how to look for them," said Davy Kirkpatrick, an author of the study.
The star cluster is located in the Large Magellanic Cloud, which is a satellite galaxy of the Milky Way.
The vast galactic structure could tell reveal something "significant" about our own galaxy, according to one scientist.
