Credit: NASA NASA’s Transiting Exoplanet Survey Satellite, fresh off a two-year extension to keep operating through 2022, has turned its cameras to image the northern sky after cataloguing nearly 1,000 candidate planets around other stars in the first year of its mission. The TESS mission reached the…

TESS probe helps scientists find potentially habitable planet, 31 light-years away
An artist’s conception depicts GJ 357 d orbiting its host star. (Cornell University Illustration / Jack Madden) Astronomers are sharing a flood of findings from NASA’s Transiting Exoplanet Survey Satellite, or TESS, including the detection of a potentially habitable super-Earth far beyond our solar system. The planet is said to circle an M-type dwarf star…

Breakthrough Watch and ESO kick off the search for more planets at Alpha Centauri
The NEAR instrument, shown here mounted on one of the telescopes at the European Southern Observatory’s Very Large Telescope facility, came into use with ESO’s VISIR imager and spectrometer on May 21. (ESO / NEAR Collaboration Photo) The European Southern Observatory and the billionaire-backed Breakthrough Watch program say they have achieved first light with a…

NASA to shut down Spitzer Space Telescope early next year
This infrared view of the butterfly-shaped W40 nebula, a star-forming cloud of gas and dust 1,400 light-years from Earth, was captured by the Spitzer Space Telescope. Credit: NASA/JPL-Caltech After a search for an outside funding source turned up empty, NASA plans to end observations with the Spitzer Space Telescope in January to conclude a 16-year…

Could Barnard’s Star harbor an icy home for life? Astronomers weigh the options
An artist’s conception shows three planets around a red dwarf star. (NASA / JPL-Caltech Illustration) Where’s the nearest exoplanet with conditions that are right for life? Over the past couple of years, astrobiologists have talked up Proxima Centauri b, which is sitting just 4.2 light-years away. But Villanova University astrophysicist Edward Guinan favors a world…

Astronomers announce first exoplanets discovered by NASA’s TESS mission
Six months into its mission scanning the sky for planets around other stars, NASA’s orbiting TESS observatory has found three previously-undiscovered worlds and hundreds candidates requiring follow-up observations, the first batch of a potential haul of up to 10,000 exoplanet detections over TESS’s planned two-year mission, astronomers announced this week. NASA’s Transiting Exoplanet Survey…

TESS planet-hunters add a ‘sub-Neptune’ world to discovery list, with more to come
An artist’s conception shows NASA’s Transiting Exoplanets Survey Satellite, or TESS, with an assortment of exoplanets. (NASA / GSFC / MIT Illustration) Less than a year after NASA’s TESS spacecraft was launched, the scientists behind the mission have unveiled their third confirmed planet, a weird alien world that’s between Earth and Neptune in size. And…

NASA says goodbye to Kepler planet-hunter
Artist’s concept of the Kepler observatory. Credit: NASA Ground controllers have beamed the final commands to NASA’s Kepler telescope, turning off the spacecraft’s transmitters and disabling the craft’s automatic recovery software after the planet-hunting observatory ran out of fuel last month. The last signals to Kepler were broadcast from a control center at the Laboratory for…
