Early superdense star clusters may have planted seeds for monster black holes.
As our evolution slows and industrialization and technology accelerates, a growing body of research suggests that human biology is struggling to keep pace.
Moss spores survived an extended stay on the outside of the ISS and remained capable of germinating once back on Earth.
There are several frozen moons in our solar system, orbiting the gas giants. Some of them have liquid water under the surface and deep down in the dark, the ocean may be boiling.
A galaxy formed around 11 billion years ago that appears to be "metal-free", indicating that it might contain a set of elusive first-generation (Pop III) stars.
The black hole was bigger than expected, and while the answer was hiding in plain sight, it still rewrites what we thought was possible.
Jeff Bezos's Blue Origin successfully launched its New Glenn rocket on Thursday with NASA twin spacecraft destined for Mars aboard, and in a breakthrough, nailed the landing of its booster.
Astronomers have detected a storm on a star other than our Sun for the first time, discovering an explosion so violent it could have stripped away the atmosphere of any planets unlucky enough to be nearby.
The Moon has no atmosphere, yet it faces an invisible bombardment more relentless than any terrestrial storm, a constant rain of micrometeoroids, tiny fragments of rock and metal traveling at speeds up to 70 kilometers per second.
Experts believe the rapid decline in their population is driven by several natural and human-made threats.
Researchers warn Antarctica is undergoing abrupt changes that could trigger global consequences.
The latest Global Tipping Points Report suggests the world's coral reefs are at risk of mass dieback. More than 80 per cent of coral reefs worldwide have bleached in a marine heatwave in the past two years.
Astronomers have discovered traces of ancient “heavy water” around a young star, revealing that some of the water found in our Solar System and even on Earth could be older than the Sun itself.
Something massive is lurking in the darkness of space, a mysterious object with the weight of a million Suns but no light to give it away.
Gravitational waves from the birth of two newborn black holes caught the attention of scientists last year. Scientists have discovered something spectacular about the birth of one of the black holes.
