After a year of analysis, the SETI Institute has concluded that 'Oumuamua, the first interstellar object known to have visited our Solar System, isn't trying to make radio contact with us.

Whether there’s life beyond Earth is one of the most profound questions we can ask. Making ourselves easier to find could be part of our first contact strategy. A new MIT study outlines a way to use existing or near-future tech to build a kind of laser lighthouse to signal to our cosmic neighbors.

It looks as if the first interstellar asteroid may be just a big rock after all. The SETI initiative Breakthrough Listen announced that preliminary observations of `Oumuamua (A/2017 U1) show no sign that the 400 m (1,300 ft) long object is other than natural with no radio transmissions detected.

While SETI is content to scan the skies for signals, Messaging Extraterrestrial Intelligence (METI) takes a more active approach. Radio transmissions containing snippets of music have been sent to a potentially-habitable planet about 12 light-years from Earth, in hopes of making first contact.

Humankind has long looked at the stars and wondered if there is intelligent life out there. And if so, could we contact them? There are a few options, but which has the greater chance of success? Sending radio messages or unmanned probes? Let's have a look.

Back in May, the Arecibo Observatory detected strange radio signals coming from Ross 128, a red dwarf star 11 light-years away. After analyzing the data closely with the help of the SETI project, the team has now revealed what they believe to be the source of the signals.

The SETI Institute, in partnership with French startup Unistellar, wants to up the game for amateur astronomers by marketing a computerized 4.5-in (11.4 cm) reflecting telescope called the "eVscope" that acts as a crowd-sourcing instrument.

Is a mysterious radio signal received by the Arecibo Observatory a message from another civilization in our galaxy? Scientists at the Planetary Habitability Laboratory say it's highly unlikely, but the peculiar signals remain a mystery.

The Search for ExtraTerrestrial Intelligence (SETI) focuses mainly on looking for radio signals from civilizations elsewhere in the galaxy, but the SETI Institute is taking a new approach – and it involves lasers.
