The mysterious signal is repeating every 16 days. A Harvard researcher says it could be of “artificial origin.” Earlier this month, Canadian researchers announced they’d discovered a powerful radio signal, emanating from a distant galaxy in bursts…

A meteorite that hit Australia 51 years ago brought to Earth the oldest matter we have ever found, writes Reuters. Inside the meteorite, which fell near the town of Murchison in 1969, 40 tiny particles of…

A radio telescope has detected a fast radio burst from another galaxy that appears to pulsate in a regular 16-day cycle, according to a new paper on the pre-print server arXiv, which has not yet been peer-reviewed. Nothing…

These supremely stable particles could explain dark matter. After decades of poking around in the math behind the glue holding the innards of all matter together, physicists have found a strange hypothetical particle, one that…

The world’s largest solar telescope has revealed its first detailed image of the sun. The Daniel K. Inouye Solar Telescope (DKIST), the world’s largest solar telescope, captured its first image of the sun — the highest-resolution image…

Neutrinos, so-called “ghost particles” scattered across the universe, can be 10 million times lighter than the mass of an electron, according to a new study. Neutrinos are referred to as ghostly because they are extremely…

This striking view of the central parts of the Milky Way has been obtained using the VISTA survey telescope at ESO’s Paranal Observatory in Chile. It’s part of a huge picture (108,200 x 81,500 pixels) which…

Scroll down for video China put world’s largest and most sensitive radio telescope into formal operation on Saturday. The Five-hundred-meter Aperture Spherical radio Telescope (FAST) will provide astronomers around the globe with a powerful tool…

Up until now, NASA has never paid too much attention to Uranus – but now the space agency wants to take a good, long look. And one of the things it might be investigating is…

People worldwide are already reporting unidentified lights in the sky as Starlink gets off the ground. It could be just the beginning. Last year saw a big increase in a certain kind of UFO spotting,…

Fluff surrounds the solid interiors of each of the three planets in the Kepler 51 star system. Each of these planets was discovered to have masses “only a few times larger than Earth’s” with radii…

The oft-delayed space observatory will be worth the wait. Paul M. Sutter is an astrophysicist at The Ohio State University, host of Ask a Spaceman and Space Radio, and author of “Your Place in the Universe.” Sutter contributed this article…

The nighttime events are among initial results from the InSight lander, which also found hints that the red planet may host a global reservoir of liquid water deep below the surface. At midnight on Mars,…
