In the binary system 4U 1820-30, a neutron star is spinning so fast around its center axis that it completes a breathtaking 716 rotations per second.
If the hypothesis that black holes are related to dark energy is proven correct, it would revolutionize conventional knowledge about black holes and dark energy.
Researchers have discovered what may be a long-hidden record of ancient impact craters on Venus, shedding light on a planetary history distinct from Earth's.
Sitting in the middle of a galaxy called LID-568, this black hole, as seen just 1.5 billion years after the Big Bang, appearing to guzzle down material at a jaw-dropping rate of over 40 times a theoretical maximum known as the Eddington limit.
A recent study demonstrates that oxygen may be produced without the need for life at depths where light cannot reach.
V4641 Sagittarii is a system about 20,000 light-years from Earth. Astronomers have now detected photons from V4641 Sagittarii carrying energies of up to a staggering 200 teraelectronvolts (TeV).
Neutron stars with a penchant for extreme spinning could be churning out one of the most sought-after particles in the Universe.
In this system, called V404 Cygni, the black hole is consuming a small star that is spiraling in very close and fast while a newfound third star circles the black hole from much farther away.
The discovery of a new, complex molecule (1-cyanopyrene) in space challenges expectations about where the building blocks for carbon are found and how they evolve.
The streaking Comet C/2024 S1 (ATLAS) has met a dramatic end, disintegrating as it approached its closest point to the sun this week.
An observatory high in the mountains of Mexico has recorded repeated emission of some of the highest-energy gamma rays ever recorded from a single point close to the galactic center.
One of the great mysteries of the Universe is where all the metal actually comes from.
Approximately 41,000 years ago, Earth’s magnetic field briefly reversed during what is known as the Laschamp event. Now scientists has created a sound visualization of this event.
Lightning storms on our planet can dislodge particularly high-energy, or "extra-hot" electrons from the inner radiation belt - a region of space enveloped by charged particles that surround Earth like an inner tube.
A set of new studies has just given us compelling origin stories for more than 90 percent of meteorites today.
