Lettuce grown on the International Space Station has been served with tacos and cheeseburgers, and it turns out to be just as nutritious as the Earth-grown version

A huge black hole from when the universe was less than a billion years old is shooting a powerful jet at Earth, and studying it could help us understand the young cosmos

Our images of deep space are spectacular, but don’t reflect what our eyes would see. Here's what their stunning true colours reveal about the cosmos

Venus’s surface is covered in strange wiggling lines that may form when colossal stacks of lava are carved by gentle winds over hundreds of millions of years

Could life on Mars have hidden from extreme weather in a cavern on the Pavonis Mons volcano? This 2011 orbiter image of an otherworldly crater has NASA asking just that

Our measurements of the Hubble constant can't seem to come up with a consistent answer. What we learn next may alter our view of the cosmos, writes Chanda Prescod-Weinstein

Pluto’s ancient oceans may have come about just after the icy world was born, melting from ice in a process that suggests the dwarf planet took just 30,000 years to form

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

Spending at least six months in microgravity can cause astronauts’ brain volumes to increase, causing pressure to build up in their heads and creating vision problems

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

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

SpaceX’s first crewed launch is planned for 27 May and will be run from a mission control with desks set six feet apart to comply with social distancing protocols

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

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

The Pulitzer Prize Board this week awarded its commentary award to The New York Times' Nikole Hannah-Jones for her essay launching the "1619 Project." This will accelerate a trend already underway: subjecting schoolchildren to a curriculum that blames slavery on capitalism and whose creator believes socialism offers the best path to racial equity.

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.

These are the Star Wars hydrating face masks from Japanese beauty product manufacturer Isshin Do. They come in Darth Vader, Stormtrooper, Darth Maul, C-3PO and Chewbacca varieties, and each contains water, glycerin, hyaluronic acid, collagen, and vitamin C to make your face feel softer than a baby Yoda's butt. For those living in Japan, you can pick up the masks for around $4 apiece from a variety of beauty retailers. For those of us not living in Japan, you can buy a 3-pack of any character for $31 from the Japan Trend Shop which, I wouldn't even kid myself, my face is not worth. I don't even buy sunscreen, I just use old spray paint I find in the garage. Also, how long you think it'll take before these are being used by couples for lewd sex acts? "Already happened." FACT. Keep going for a shot of each while I try to pretend I didn't just imagine some Chewbacca on C-3PO bedroom role playing.
