A team of astronomers have mapped the nearby universe, from about 425 million to 800 million light-years (which translates to some 130 to 250 megaparsecs), and discovered the largest-known structure residing there.
Bennu has a 1-in-2,700 chance of colliding with Earth in 2182, causing a global winter and drought.
New research shows that when an asteroid slammed into the moon billions of years ago, it carved out a pair of grand canyons on the lunar far side.
Scientist have concluded water did not arrive as early during Earth's formation as previously thought.
In April of 2024, astronomers spotted an unusual event that astronomers named EP240408a. While the explosion was originally thought to be a gamma-ray burst, it now appears it might represent a new class of powerful cosmic explosion.
Asteroid, 2024 YR4, is on a path that might lead to a collision with our planet on 22 December 2032. Calculations suggest there is currently around a 1-in-77 chance that the asteroid will crash into our planet at that time.
By some reckoning, as few as 15 percent of supermassive black holes are hidden behind dust clouds.
During a flyby of Jupiter’s moon Io on December 27, 2024, NASA’s Juno spacecraft discovered an astonishing volcanic hotspot in the moon’s southern hemisphere.
Though it's a cold, dead planet, Mars still has its own natural beauty about it. This image shows us something we'll never see on Earth - Martian CO2 geysers.
Recently scientists found 266 lunar ridges on the far side: evidence the Moon has been active within the past 200 million years and might still be active today.
New findings reveal that a NASA mission traveled to an asteroid that may have once been covered in salty lakes containing organic molecules.
Astronomers have discovered an extraordinary new giant radio galaxy with plasma jets 32 times the size of our Milky Way.
Astronomers have found two planets around two separate stars that are succumbing to their stars' intense heat. Both are disintegrating before our telescopic eyes, leaving trails of debris similar to a comet's.
A new study argues that Pop III stars flooded the cosmos with water. Based on this, by 100 to 200 million years after the Big Bang, there could have been enough water and other elements in molecular clouds for life to form.
Fast radio bursts (FRBs) are puzzling phenomena because their details are so difficult to resolve. Astronomers added another piece to the puzzle with the detection of an FRB that seems to originate in a dead galaxy.
