In May 2018, a radar facility in Tromsø, Norway, trained its antennas on GJ237b, a potentially habitable exoplanet located 12 light years from Earth. Over the course of three days, the radar broadcast a message toward the planet in the hopes that there might be something, or someone, there to receive it. Each message consisted of a selection of short songs and a primer on how to interpret the contents.
This was the second iteration of Sónar Calling GJ273b, an interstellar messaging project by the nonprofit METI International that began in 2017. Although both transmissions were billed as a " music lesson for aliens ," the second broadcast was notable for rehabilitating an extraterrestrial language developed by the physicists Yvan Dutil and Stephane Dumas in the late 1990s.

S o you've received a message from an extraterrestrial intelligence. Congratulations! You are now at the centre of one of the most important events in human history. But now comes the hard part: what do you say in return – and, more importantly, how do you say it?
Any solution to the problem of interstellar communication comes laden with assumptions about the nature of extraterrestrial intelligence and inevitably reflects the technological sophistication of the era.

In February, the Spanish pilot Daniel González climbed into a small aerobatic plane at the Sabadell Airport outside Barcelona and fired up its single prop engine. Once he was in the air, González began a steep climb for about six seconds before entering a nosedive . The plane's rapid descent created a microgravity environment in the cockpit and for a few seconds, González felt what it was like to be an astronaut.
This sort of parabolic flight isn't remarkable for an experienced aerobatic pilot like González. But the cargo on his flight was a little unusual: In the passenger seat of the plane sat a small box, loaded with tubes of frozen human sperm .

By analysing data from TESS scientists will be able to determine which distant planets they should focus on in the search for extraterrestrial intelligence (SETI).
The space telescope uses an array of wide-field cameras to perform a survey of 85 percent of the sky.
TESS is capable of studying the mass, size, density and orbit of a large cohort of small planets, including a sample of rocky planets in the habitable zones of their host stars.
