Moving through cosmic forests and spider webs in deep space in search of answers on the origin of the Cosmos. “We have tested a scenario in which dark matter is composed by non-stellar black holes, ...

A tiny black hole may pass through our solar system once every ten or so years, researchers have suggested, and this could be detected by watching Mars wobble. This estimate is based on an idea ...

Astronomers have accidentally discovered a dark galaxy filled with primordial gas untouched that appears to have no visible stars. The researchers behind the discovery say this galaxy, designated ...

For about 50 years, the scientific community has been grappling with a substantial problem: There isn’t enough visible matter in the universe. All the matter we can see — stars, planets, cosmic dust ...

A new paper explores the idea of asteroid-sized objects that may be causing gravitational ripples in our cosmic neighborhood. Reading time: Reading time 2 minutes Black holes are some of the most ...

Every decade or so, at least one microscopic black hole might be flying through our solar system, creating minuscule, detectable gravitational distortions. If astronomers can confirm the existence of ...

Could slight wobbles in the orbit of Mars be caused by microscopic black holes that have existed since the Big Bang? This is what a recent study published in Physical Review D hopes to address as a ...

Dark matter is a mysterious substance composing most of the material universe, now widely thought to be some form of massive exotic particle. An intriguing alternative view is that dark matter is made ...

Our initial name ‘dark star’ is a misnomer,” Katherine Freese explained, highlighting the contradiction at the core of one of ...

A gamma ray glow at our galaxy’s center has puzzled scientists for almost two decades. New computer simulations back the ...

One day a little more than five years ago, Ely Kovetz was having lunch with his colleagues at Johns Hopkins University, in Baltimore, discussing a tantalizing rumor. Like many in the physics community ...
