for new earth-like planets have been discovered orbiting our nearest sun-like star Tau Ceti Tau Ceti is only a mere 12 light-years away and is visible with the naked eye the four new exoplanets have masses as low as 1.7 earth-mass making them among the smallest planets ever detected around nearby sun-like stars according to an article published by the University of Santa Cruz California two of the exoplanets are within Tau steadies habitable zone meaning that they could support surface water and may have daylian oceans the exoplanets were discovered using astronomical data from the harps spectrograph aka the exoplanet hunter which is part of the European Southern Observatory in Chile and the WM Keck Observatory in Mauna Kea Hawaii the last few years scientists and astronomers have been making lots of new exoplanet discoveries by perfecting a technique for measuring the Doppler shifts in the wobbling of a star caused by the gravitational pull of nearby orbiting planets scientists are now able to detect variations in the movement of a star as small as thirty centimeters per second and they are hoping to soon reach a ten centimeter per second measurement milestone which is the limit required for detecting earth analogs read more about the newest exoplanets in the CNET article at cnet.com you
