A black hole gobbled up a star in deep space and flung a high-energy subatomic bullet at the Earth. Don’t worry, the planet’s doing fine. On Oct. 1, 2019, Earth was struck by an invisible, high-energy cosmic bullet moving at almost the speed of light....

In a recent paper in the Proceedings of the National Academy of Sciences a group of researchers led by Maria Hjorth and Simon Albrecht from the Stellar Astrophysics Centre, Aarhus University, have published the discovery of a special exoplanetary system in which two exoplanets are...

This week, the grandest and most spectacular of all constellations can be found due south and standing upright around 7 p.m. local time, and dominating our winter skies like — to use the words of astronomer Robert H, Baker — “a gigantic piece of jewelry.”...

This article was originally published at The Conversation. The publication contributed the article to Space.com’s Expert Voices: Op-Ed & Insights. James Okwe Chibueze, Associate Professor, North-West University Here on Earth, we pay quite a lot of attention to the sun. It’s visible to us, after...

The red supergiant star Betelgeuse is nearing the end of its life, and researchers are preparing for what it will look like when the star dies in a fiery explosion called a supernova.Located in the constellation Orion, the star is about 1,000 times the size...

In 1987, astronomers observed an incredible star explosion in a galaxy not too far away in the Large Magellanic Cloud. Now, researchers suggest that the famed supernova, called 1987A, was created by a blue compact supergiant star. The type of supernova created by the blue...

Astronomers have revealed the gigantic atmosphere of the red supergiant star Antares in stunning, unprecedented detail. Using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile and the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) in New Mexico, an international team of researchers...

Astrophysicists have spotted the strangest gravitational-wave signal yet, an observation that could force scientists to rewrite what they know about the cosmos. Gravitational waves form when massive objects distort spacetime surrounding them and send ripples out across the universe. Scientists caught the first-ever detection of...

An unstable massive star has suddenly vanished from view, and astronomers aren’t sure if it collapsed into a black hole or is playing peek-a-boo behind galactic dust. The star was too far away to spot on its own, but it showed up in the spectrum,...

If you want the clearest view of the night sky, you’ll have to pack a warm jacket. Dome A, or Dome Argus, an ice dome perched high on the Antarctic Plateau, could be the ideal place to get a clear view of the stars from...
