Neutron stars explained through stellar remnants and collapsed stars, revealing extreme density, gravity, magnetism, and ...

In the dense environment of the early universe, dark matter particles would collide with, and annihilate, each other, ...

According to the theory, our reality is encoded on the boundary of a black hole within a much larger universe.

The discovery of a hidden supermassive black hole inside an ancient galaxy suggests that some of our universe's most extreme objects could be invisible unless observed in infrared wavelengths, James ...

In smaller dark stars, when their dark matter runs out, normal nuclear fusion can begin, and they gradually become normal ...

Scientists have discovered a giant cosmic filament where galaxies spin in sync with the structure that holds them together.

Comet‍‌‍‍‌‍‌‍‍‌ 3I/ATLAS is just the third object that we know of that has been observed to pass through our solar system ...

In any other year, the supermassive black hole mentioned above would probably scoop the award for most striking outburst, but not in 2025. This year, that accolade goes to a flare designated ...

Astronomers say 3I/ATLAS is so unusual that it is forcing a rethink of probability distributions used to model interstellar ...

Our own planet represents a tiny fraction of the peculiar phenomena that can be found lurking throughout the cosmos, and every day astronomers turn up new surprises. In this gallery, we take a look at ...

But that’s nothing compared with PSR J2322-2650b, an object the mass of Jupiter studied recently by the James Webb Space Telescope. This planet’s equatorial diameter is about 38 percent wider than its ...

Physicists at the Cubic Kilometre Neutrino Telescope Initiative, KM3NeT, built a cathedral of glass spheres that listens for ...
