Hacker network Anonymous has made headlines today, this time claiming that NASA is on the verge of announcing evidence of alien life.It's a pretty bold statement, but before you get too excited, we've checked the science, and let's be clear right up front that Anonymous doesn't appear to have any substantial new evidence to back up their speculation.In fact, their latest video announcement centres around the Kepler SpaceTelescope's latest discovery of 219 new planet candidates outside our Solar System, as well as comments made by Associate Administrator of NASA's Science Mission Directorate, Thomas Zurbuchen at a US government hearing back in April."Taking into account all of the different activities and missions that are specifically searching for evidence of alien life, we are on the verge of making one of the most profound, unprecedented, discoveries in history," Zurbuchen said during the recent congressional hearing of the committee on 'Advances in the Search for Life', on April 26.He was also pretty excited about the Kepler announcement last week:Anonymous has taken Zurbuchen's enthusiastic testimony from that hearing(which you can watch in full at the bottom of this story), alongside the latest Kepler discovery - as well as a few other statements from former astronauts and alien enthusiasts - as evidence "something is going on in the skies above".So far it has discovered more than 4,000 planet candidates outside our Solar System, including 30 planets similar in size to Earth that are located in the habitable zones of their stars - that means they're not so far away that water would freeze, and not too close that everything would be burnt to a crisp.Notably, earlier this year NASA announced the discovery of a "sister solar system" - a star system known as TRAPPIST-1 that has seven potentially Earth-like planets orbiting it, and is a relatively close 39light-years away."The TRAPPIST-1 system is just 39 light years away and its discovery tells us that there is plenty of planet making material in our little corner of the solar system, indicating that finding Earth-like planets may actually be closer to us than we originally thought. Future study ofthis planetary system could reveal conditions suitable for life," said Zurbuchen at the hearing back in April.Next year, NASA will launch the James Webb Space Telescope -an even moresensitive planet hunter - which will be an even more sensitive planet hunter, that will be able to detect the chemical fingerprints of water, methane, oxygen, ozone in an exoplanet's atmosphere - something that will help us sniff out signs of habitability if they're there.In addition to looking for signs of life on planets outside of our own Solar System, NASA has also made significant advances when it comes to our own neighbouring planets - including the discovery of essential lifebuilding block hydrogen in the frozen oceans of Saturn's moon Enceladus, and evidence that Jupiter's watery moon Europa has oceans with very similar chemical composition to our own. So Anonymous is right in one way - NASA is closer than ever to having the tools to find evidence of alien life... but unfortunately that doesn't mean that evidence already exists, or even that we'll find it inour lifetime.
