Cecilia Payne-Gaposchkin, who discovered that hydrogen dominates our universe, finally gets the recognition she deserves in a rich biography, What Stars Are Made Of

An unusually round and symmetrical deposit on Mars may be the result of an impact that popped the surface of the planet, causing a volcanic eruption less than 200,000 years ago

Thousands of dead satellites and chunks of debris in orbit are a threat to active satellites, but rockets that launch clouds of talcum powder may prevent a disastrous collision

Strange particles observed by an experiment in Antarctica could be evidence of an alternative reality where everything is upside down

An enormous rocky planet orbiting a distant star may be a gas giant that has had its atmosphere ripped off, which could help us understand how huge worlds like Jupiter form

Brown dwarfs, which are halfway between huge planets and small stars, have extremely powerful winds whipping around them at speeds of about 650 metres per second

A star that swoops close to the Milky Way’s supermassive black hole has a strange, looping orbit that proves Einstein was right about the gravity of black holes

Arrokoth, a strange two-lobed space rock, was hit by another rock at some point – the collision may have snapped Arrokoth’s narrow neck before it reformed again

Mars could have had an ancient ocean in its northern hemisphere, and a large raft of volcanic rock may have floated across it to settle into mounds we can see today

Strange orbits of distant space rocks have been used to infer that the solar system has an unseen ninth planet, but those orbits may be less strange than we thought, meaning there is no need for a new planet

We know that there is at least one planet orbiting Proxima Centauri, the nearest star to our solar system, and now astronomers may have taken the first picture of a second world

A bunch of asteroids near Jupiter and Neptune with orbits perpendicular to the plane of the solar system may have come here from a different star system

The question of how the brain gives rise to subjective experience is the hardest of all. Mathematicians think they can help, but their first attempts have thrown up some eye-popping conclusions

Stars that are similar to the sun in every way we can measure are mostly more active than the sun, which hints that the sun’s activity may ramp up someday, risking solar eruptions

Weird blasts of radio waves from space called fast radio bursts have been baffling astronomers since they were discovered, but after finding one in our galaxy we may finally know what creates them

From vintage satellites to lunar rovers, space archaeologist Alice Gorman is teasing out a unique history of humanity from the objects we've dispatched from Earth

China just tested its biggest rocket yet, along with a new capsule designed to carry humans to its planned space station, the moon and beyond

We’ve found a 200-metre cliff in Mars's Hellas basin, the first evidence of a river that flowed on the planet for more than 100,000 years

Astronomers found a star that appeared to be orbiting nothing at all – but it’s actually the closest black hole ever at just 1000 light years away

Mercury is much denser than the other rocky planets in the solar system, and that may be because a collision vaporised its surface and the debris was blown away by the sun

About 80 per cent of stars in the Milky Way’s central bulge have relatively close encounters with another star, which can fling off any planets orbiting them

In 1847, members of the Choctaw Nation sent relief money across the Atlantic to a starving Ireland - something the Irish, who lost more than a million people in a famine made worse by British indifference, have never forgotten. The Irish are now giving financial aid to Native American tribes hit with a pandemic that has been made worse by American incompetence.

After more than three long years, the Justice Department has finally lived up to its name by dropping charges against my former boss, former National Security Adviser and retired Army Lt. Gen. Michael Flynn. He should have never been prosecuted.

Will Flynn be the right wing's Nelson Mandela? Of course that's insulting - but so is this entire presidency

Megyn Kelly's exclusive sit down with Tara Reade

I was not surprised either that it took two-plus months for arrests to come of two men and murder charges in the case. This only after the GBI was rightly called in.

New labor economy data paints a fuller - and bleaker - picture of the economy.

The country faces the same problem today it did two months ago: There are not enough tests to contain the virus.

There is something deeply unsettling about the lionization of Andrew Cuomo and his handling of the epidemic, especially in the light of the raw statistics

In light of the newly declassified documents, it is clear that understanding what happened in that January 5 Oval Office meeting is essential to understanding the corrupt operation against the Trump administration.

The Justice Department's move was the latest example of the attorney general's effort to chisel away at the special counsel investigation and emphasize an alternate narrative.
