A handheld laser could help find aliens on Mars or Jupiter's moon Europa by analyzing the chemistry of tiny planetary materials. A University of Maryland–led team announced the NASA-funded device, a ...

A new Nasa-funded laser could help scientists find alien life. Researchers built the laser to detect signs of life and for identifying materials taken from other planets. But they also had to shrink ...

A pair of MIT researchers has proposed a radical method for making our presence known in the universe. In a new feasibility study, the team says it could be possible to use laser technology as a ...

Experts still debate whether sending signals into space is actually a good idea – or whether it will alert potential invaders to our presence. But a new plan suggests that we could create a ‘laser ...

An amateur astronomer was gazing at the stars through her telescope when she noticed something bizarre. Just past her sighting of the moon, Paula Gilley could see Saturn. Article continues below ...

A new laser has been developed by scientists to detect aliens on other planets. The miniature device has been tailored to NASA space missions with an aim to revolutionise the search for ...

A laser cloak could hide Earth from potential alien invaders. Professor David Kipping, an astronomer at Columbia University in New York, has said the relatively simple concept could make the world ...

The technology already exists to create a planetary porch light to tell aliens we're at home A GIANT telescope could use a powerful laser to tap out messages to alien stargazers, a new study has ...

Scientists have gone back to scanning a pulsating star from a distant galaxy in hope of finding laser emissions that could provide more information about it. The star known as ‘KIC 8462852’ or ...

The KIC 8462852 star was first spotted by online astronomers Planet Hunters in 2015, which appeared to be dipping in brightness. Astronomers struggled to explain why the star’s brightness was ...
