Scientists discover galaxy that’s almost entirely dark matter
Astronomers have discovered a galaxy with very little or no stellar mass.
Galaxies like these are called ‘dark galaxies.’
It contains clouds of gas but very...
Scientists detect a black hole table for two
Astronomers have discovered a galactic table for two—a pair of unusually close black holes that are feeding together after their respective galaxies collided.
Ghostly neutrinos provide new path to study protons
Scientists have discovered a new way to investigate the structure of protons using neutrinos, known as ‘ghost particles.’
Scientists develop a new model for dark matter
Scientists have now proposed a new candidate for dark matter: HYPER, or "HighlY Interactive ParticlE Relics."
How a 3 cm glass sphere could help understand space weather
UCLA researchers reproduced the gravity that exists on or near stars and other planets inside of a 3 cm glass sphere.
How to shelter from a nuclear explosion
There is no good place to be when a nuclear bomb goes off. Anything too close is instantly vaporized, and radiation can pose a serious health threat even at a distance.
Astronomers capture radio signal from distant galaxy
How do stars form in distant galaxies?
Astronomers have long been trying to answer this question by detecting radio signals emitted by nearby galaxies.
However, these...
How do rocky planets really form?
Scientists unveil a unified theory for rocky planet formation.
New study reveals a star’s unexpected survival
As the star is shredded, its remnants are transformed into a stream of debris that rains back down onto the black hole to form a very hot, very bright disk of material swirling around the black hole, called an accretion disc.
Scientists discover system’s second earth-size planet
Scientists have identified an Earth-size world, called TOI 700 e, orbiting within the habitable zone of its star – the range of distances where liquid water could occur on a planet’s surface.
