SETI

  • Neptune's collection of moons has officially grown to 14. Originally discovered in 2013 and designated S/2004 N 1, this tiny world is described more accurately in a new paper, which also gives it an origin story and, finally, a catchier name. Say hello to Hippocamp.
  • 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.
  • ​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.
  • On Sunday the Chinese Academy of Sciences announced that the Five-hundred-meter Aperture Spherical radio Telescope (FAST)​ has begun operations.
  • ​A possible signal from ET turned out to be a false alarm as scientists confirm that a message seemingly from the stars came from Earth. Recent reports had suggested that a powerful radio signal might be a deliberate message, but an old Cold War military satellite is the culprit.
