All the singularities of gravitational collapse are "clothed" by the event horizons of black holes – meaning we could never observe one. This is called cosmic censorship.
A new research suggests that the South Pole-Aitken basin may not have formed the way we thought, and may be much bigger than previous studies suggest – a discovery that has exciting implications for future lunar missions to the basin.
What would happen to our mature, sedate Solar System if it suddenly gained another member? That would depend on the object's mass and the eventual orbit that it found itself in.
Using the largest gravitational wave detector ever made, we have confirmed earlier reports that the fabric of the Universe is constantly vibrating.
A team of astronomers has found that Venus has never been wet, despite decades of speculation that our closest planetary neighbour was once much more like Earth than it is today.
There is a radical idea that Earth was seeded not just with the building blocks of life but life itself.
A new study suggests that dark matter may have originated from a separate "Dark Big Bang," occurring shortly after the birth of the universe.
Researchers set a new benchmark, capturing the physics of dark and atomic matter with unmatched precision.
The Milky Way is only one system and may not be typical of how other galaxies formed. That's why it's critical to find similar galaxies and compare them
A team of researchers has just found that the predicted curvature of space-time calculated using relativity does not always quite match up to what we observe
The history of water on early Mars is not certain. Determining when water first appeared, where and for how long, are all burning questions that drive Mars exploration.
A still-forming planet has been detected early in its birth process, thanks to what may have been a chance encounter with a passing star that flipped part of the obscuring disk out of the way, exposing the baby planet.
NASA's Curiosity Mars rover viewed these yellow crystals of elemental sulfur using its Mast Camera. The discovery marks the first time this mineral has ever been found in a pure form on Mars.
Measurements over the years show that the planet's upper atmosphere is cooling and that the temperature has halved. None of the other planets experienced the same changes.
For the first time, we have succeeded in taking a zoomed-in image of a dying star in a galaxy outside our own Milky Way. The star WOH G64 is located a staggering 160 000 light-years from us.
