In a stroke of luck, astronomers saw the comet C/2025 K1 (ATLAS) break into four or five fragments in November after it passed close to the sun.

Astronomers have identified the first clear evidence of a magnetar forming during a superluminous supernova, offering new insight into some of the brightest explosions in the universe.

Lamar Jackson trade speculation is beginning to heat up. Here is the latest on why rumors are starting to increase.

Researchers found a magnetic star core acting as a high speed engine to power a record breaking luminous supernova.

When most people think of a supernova, they're thinking of a Type II core-collapse supernova. These are massive stars that have reached the end of their time on the main sequence. They've used up ...

One of the largest known stars in the cosmos is poised for catastrophe. After witnessing the massive object undergo a dramatic transformation, a team of astronomers say the star is on the verge of ...

When I first started running, I thought a solid core workout looked like blasting through some crunches and sit-ups and then checking for any signs of visible ab definition. It turns out I had core ...

The oceans are the largest entity on Earth’s surface. All that blue, however, may be dwarfed by an immense reservoir of hydrogen concealed in the planet’s heart. Experiments indicate that enough ...

Picture all of Earth’s oceans, which cover about 70% of the planet and are mostly made of hydrogen. Now multiply that by nine. That may be the amount of hydrogen in Earth’s core, possibly making it ...

Earth’s core may contain up to 45 oceans’ worth of hydrogen, a new study finds—an estimate that suggests that the planet formed from a gas-and-dust disk that was rich in the universe’s lightest ...

A supercharged neutrino that smashed into our planet in 2023 may have been spit out by an exploding primordial black hole with a "dark charge." If true, this theory could lead to a definitive catalog ...
