The National Observatory of Athens, Greece played a pivotal role in the first optical communication link with a spacecraft in ...

Just kidding: this is, of course, the ESA’s Optical Ground Station telescope in Tenerife—in the process of laser tagging the ISS to establish a data connection.

The two laser telescopes are exchanging data at 1.2 gigabits per second, according to NASA. "Together, they complete NASA’s first two-way, end-to-end laser relay system," NASA said in a statement.

The telescope is part of the Laser Interferometer Space Antenna (LISA) mission led by the European Space Agency (NSA) in partnership with NASA.

Astronomers have detected a powerful radiowave laser, known as a megamaser, in space. Pictured is an artist's illustration showing how the MeerKAT telescope detected this record-breaking megamaser.

Welcome to the Daily Telescope. There is a little too much darkness in this world and not enough light, a little too much pseudoscience and not enough science. We'll let other publications offer ...

“We have developed a universally applicable telescope that is both a transmitter and receiver unit.” If and when they are deployed, the new telescopes must be able to withstand both the environmental ...

Indeed, lasers can be used as lasers, and a giant laser gun in space would be a huge threat. Fortunately, China’s new space laser isn’t made to attack, but rather to locate other satellites and prove ...

We’ve showed you the Paranal Observatory’s laser-guided telescopes before, but never in gorgeous HD motion, replete with clear stars and deftly swiveling machinery. This is definitely one you ...
