Mysterious Objects in Space Could Be Giant Dyson Spheres

One group of scientists thinks that we may already have detected technosignatures from a technological civilization's Dyson spheres, but the detection is hidden in our vast troves of astronomical data.

Astronomers uncover a mysterious object in Milky Way

An international team of astronomers have found a new and unknown object in the Milky Way that is heavier than the heaviest neutron stars known and yet simultaneously lighter than the lightest black holes known.

NASA Detects Mysterious Signal Coming From Outside Our Galaxy

NASA astronomers have discovered an unexpected "signal" coming from outside our galaxy, which they can't explain.

Hubble Finds Weird Home of Farthest Fast Radio Burst

Astronomers using NASA's Hubble Space Telescope have found a rare fast radio burst (FRB). This new FRB is particularly weird because it erupted halfway across the universe, making it the farthest and most powerful example detected to date.

Ancient, Gigantic Star Exploded in a Way We Didn't Think Was Possible

A strange star in the Milky Way bares the signature of a unique explosion of a giant star that once existed billions of years ago in the era of the cosmic dawn.

Discovery of 'Big Ring on the Sky' structure

The latest discovery of an ultra-large structure called the "Big Ring" adds to "mounting evidence" that challenges what we know about the universe.

Never-before-seen Fast Radio Burst sheds new light on deep space signals

A new study published in the Monthly Notices of the Royal Astronomical Society has now shed new light on them, after spotting a “highly active” repeating FRB signal that is behaving differently to anything ever detected before.

Scientists Mystified by Rare, High-Energy Cosmic Ray

Scientists in Utah have detected the second-most energetic cosmic ray ever seen. The powerful particle rivals the highest-energy cosmic ray on record, called the Oh-My-God particle, which was spotted in 1991.

The colossal ‘Tasmanian devil’ exploding in space

Last year, global astronomers picked up evidence of an explosion called a luminous fast blue optical transient, or LFBOT. But the bizarre thing about this explosion was that it kept exploding.

Ultra-Fast Radio Bursts Detected Lasting Only Millionths of a Second

A recent study examines the discovery of what astronomers are dubbing "ultra-fast radio bursts", a new type of fast radio bursts (FRBs) that the team determined lasts for a mind-boggling ten millionths of a second or less.

"Starquakes" could explain mystery signals

Fast radio bursts, or FRBs, are an astronomical mystery, with their exact cause and origins still unconfirmed. A recent research found several notable similarities between FRBs and earthquakes.

Hubble finds bizarre explosion in unexpected place

A very rare, strange burst of extraordinarily bright light in the universe just got even stranger. The phenomenon, called a Luminous Fast Blue Optical Transient (LFBOT), flashed onto the scene where it wasn't expected to be found.

Newly Discovered World Challenges Our Understanding of Planets

TOI-4860b happens to orbit a tiny star, completing each lap in just 1.52 days. It joins a small number of worlds that pose a fascinating puzzle - there are currently no known formation pathways for such chonkin' planets around such small stars.

There could still be a ninth planet in our solar system

This hypothetical planet is provisionally known as Planet 9. Computer simulations show it must be a very large planet, consisting of between four and eight times the mass of the Earth and at least ten times the distance of Pluto.

Another Object Emitting Strange Radio Signals in Our Galaxy

A strange radio signal pulsing from a spot 15,000 light-years away could point to an unconfirmed type of star.
