Today’s global coral bleaching events are the worst kind of climate warning.

In 1996 Nasa and the White House made the explosive announcement that the rock contained traces of Martian bugs. The meteorite, catalogued as Allen Hills (ALH) 84001, crashed onto the frozen wastes of Antarctica 13,000 years ago and was recovered in 1984. Photographs were released showing elongated segmented objects that appeared strikingly lifelike.

Putting data centres in space isn't going to happen any time soon Could AI's insatiable thirst for colossal data centres be fixed by launching them into space? Tech companies are eyeing low Earth orbit as a potential solution, but researchers say it's unlikely in the near future due to a mountain of difficult and unsolved engineering issues. The huge demand for, and investment in, generative AI products like ChatGPT has created an unprecedented need for computing power, which requires both vast amounts of space and gigawatts of power, equivalent to that used by millions of homes. As a result, data centres are increasingly fuelled by unsustainable sources, like natural gas, with tech companies arguing that renewable power can neither produce the amount of power needed nor the consistency required for reliable use. To solve this, tech CEOs like Elon Musk and Jeff Bezos have suggested launching data centres into orbit, where they could be powered by solar panels with constant access to a higher level of sunlight than on Earth.

On a commercial thoroughfare in old town Pasadena, California, a stone's throw from NASA's Jet Propulsion Laboratory (JPL), you'll find the Neon Retro Arcade. Among its collection of vintage video games is the 1979 Atari classic Asteroids, in which a pixelated spaceship shoots down a barrage of space rocks to stave off fatal collisions. After long days of work at JPL, Amy Mainzer used to rack up high scores on that console. "It was a hoot," she says. It was also apt, considering she oversees a space mission designed to spot dangerous asteroids before they crash into Earth. That mission, the Near-Earth Object (NEO) Surveyor, was conceived in the early 2000s and finally got the green light in 2022. Its components are now being built, tested, and assembled in clean rooms across the United States ahead of its planned launch in September 2027. "We're in the thick of building everything," says Mainzer, NEO Surveyor's principal investigator and now an astronomer at the University of California, Los Angeles (UCLA).

Jonny Kim returned after eight months aboard the International Space Station. Breakthroughs, discoveries, and DIY tips sent every weekday. After 245 days in orbit aboard the International Space Station (ISS), one NASA astronaut and two cosmonauts have safely returned to Earth. NASA's Jonny Kim along with Roscosmos cosmonauts Sergey Ryzhikov and Alexey Zubritsky landed near the town of Zhezkazgan, Kazakhstan on December 9, and are now undergoing the standard post-mission health screenings. Kim officially became an astronaut in 2017.

How a 1993 plan to launch ads into space turned into a national freakout. In the 1990s, space was for sale. Breakthroughs, discoveries, and DIY tips sent every weekday. In 1993, Mike Lawson, an aerospace entrepreneur based in Roswell, Georgia, unveiled his vision for a brave new future of advertising: space billboards. This wasn't a half-baked scheme: Lawson had meticulous plans for a proposed 1996 launch: His team of engineers would shoot a package of tightly-wound mylar into orbit about 180 miles above the Earth.

Scientists have revealed a grim prospect for humanity's future, as they warn Earth will eventually be consumed by the sun. In roughly five billion years, our star will burn the last of its hydrogen fuel and begin expanding into a monstrous red giant.

At its peak, our lunar satellite will appear eight per cent larger and 16 per cent brighter than usual. The phenomenon occurs because the moon's orbit is not perfectly circular around Earth, meaning at times it is slightly closer or slightly further away.

The US company says putting AI processors in space would ease pressure on the Earth's resources. The US company says putting AI processors in space would ease pressure on the Earth's resources. US technology company's engineers want to exploit solar power and the falling cost of rocket launches Google is hatching plans to put artificial intelligence datacentres into space, with its first trial equipment sent into orbit in early 2027. Its scientists and engineers believe tightly packed constellations of about 80 solar-powered satellites could be arranged in orbit about 400 miles above the Earth's surface equipped with the powerful processors required to meet rising demand for AI. Prices of space launches are falling so quickly that by the middle of the 2030s the running costs of a space-based datacentre could be comparable to one on Earth, according to Google research released on Tuesday.

'Great Migration' involves far fewer wildebeest than we had thought An estimate that as many as 1.3 million wildebeest move across the Serengeti Mara landscape each year has been cut down to size using AI East Africa's "Great Migration" is generally estimated to involve as many as 1.3 million wildebeest. But in reality, fewer than 600,000 of the animals might move across the Serengeti Mara landscape each year, according to an AI analysis of satellite images. The Great Migration sees wildebeest, zebra and antelopes move between feeding and breeding grounds in Kenya and Tanzania, while also trying to dodge predators including lions, crocodiles and hyenas. Lions' record-breaking swim across channel captured by drone camera Assessing the number of animals involved is a tough task, traditionally achieved using crewed aerial surveys. Researchers can only survey a small area at a time, however, so they use statistical models to extrapolate densities across unsurveyed regions, which can introduce errors given herds are unevenly distributed and constantly on the move.
