The milestone is long overdue.

A former Nasa scientist claims evidence of life was found on Mars in the 1970s but was ignored. Viking landers, a pair of space probes, were sent to the Martian surface more than 40 years ago to explore the planet. One of the tests they ran was known as Labeled Release, or LR, which was intended to look for signs of life.  Back in the lab, the results seemed to indicate something was happening on the surface.

Nasa found evidence of alien life in the 1970s, according to a former senior scientist – and ignored it. The Viking landers were sent to the Martian surface more than 40 years ago, with the aim of exploring the planet. They included an experiment known as Labeled Release, or LR, which was intended to look for signs of life on the planet.

One of the first profiles of interstellar comet Borisov has been published, and it looks about the same as most other comets. What it doesn't look like is the first interstellar object, Oumuamua, which made its closest pass by Earth exactly two years ago today.

ESA probe captures new photos of 700km dried-up river system on Mars

For every action, there is a reaction: that is the principle on which all space rockets operate, blasting propellant in one direction to travel in the other. But one NASA engineer believes he could take us to the stars without any propellant at all.

Strange machine will explore surface ahead of future human landings

UC Riverside-led research shows our galaxy is undergoing a massive merger with its largest satellite galaxy, the Large Magellanic Cloud

There's more testing needed before astronauts fly to space on Crew Dragon.

Things haven’t quite gone to plan for India's Chandrayaan-2 mission, with the team losing the spacecraft’s Vikram lander following a touchdown attempt last month. But there is still plenty of science to come as the probe continues to circle the Moon, with the latest imagery relayed by the orbiting…

A cataclysmic energy flare started near the massive black hole in our galaxy, a new research says.

China has broken new ground, successfully growing cotton on the moon for the first time. The experiment was part of the Chang'e 4 project, in which China is exploring the far side of the moon with a lander. The cotton plant was one of several organisms encased in a mini biosphere aboard the lander.

The first all-female spacewalk is back on, six months after a flap over spacesuits led to an embarrassing cancellation.

An international team of scientists is constructing the Large Synoptic Survey Telescope in Chile, which will be an essential tool for asteroids alert.

There can be no doubt that Nasa is serious about trying to land astronauts on the moon by 2024. Even though the Artemis programme has yet to be fully funded, Nasa has issued a call to US companies for a lunar landing spacecraft that will place the first woman and the next man on the moon’s surface. The call has been sent out in draft form twice already this year, allowing private companies to comment and help Nasa shape the request. Now those companies have until 1 November to submit their finished proposals. From these, two companies will be contracted to provide the landers.

When China's Chang'e-4 spacecraft landed on the lunar far side on 3 January 2019, it made history. It was the first spacecraft to visit that part of the Moon, and among its payload was a 2.6 kg (5.7 lb) mini-biosphere called the Lunar Micro Ecosystem

Submissions are due November 1st

Comet 2I/Borisov is releasing cyanogen—similar to comets from our own solar system

But what IS it?

China’s Yutu-2 lunar lander just sent back new images of a strange substance it found near a small crater on the far side of the Moon. Last month, the team behind the lunar rover claimed it had found a “colored mysterious substance” as described in the rover’s diary, which claimed that the material’s “shape and color is significantly different from the surrounding lunar soil.”
