    The Kepler and Dawn spacecraft both ran out of fuel, marking the end of an era that transformed our understanding of both our solar system and others.

  • Kepler Space Telescope concludes mission that discovered thousands of far-flung worlds

    Jason RhianOctober 30th, 2018

    The Kepler Space Telescope has been on duty for more than nine years. Its mission(s) came to an end when the spacecraft expended the last of its fuel. It leaves behind a wealth of data about exoplanets that has revolutionized humanity's understanding of our galaxy.

  • Has NASA’s Kepler Space Telescope detected first exomoon?

    Laurel KornfeldOctober 4th, 2018

    NASA's Kepler Space Telescope may have discovered evidence of a moon orbiting a planet around a distant star.

  • NASA’s planet-hunting TESS mission shares ‘1st-light’ image

    Jim SharkeySeptember 23rd, 2018

    Scientists with NASA's planet-hunting Transiting Exoplanet Survey Satellite (TESS) mission recently released images from the spacecraft's first science orbit. The mission's "first light" image was a detailed picture of the southern sky taken with all four of the spacecraft's wide-field cameras.

  • Our SpaceFlight Heritage: Spitzer telescope’s top 15 discoveries

    Laurel KornfeldAugust 27th, 2018

    To celebrate the 15th anniversary of the Spitzer Space Telescope's operations in space, NASA's Jet Propulsion Laboratory (JPL), which manages the mission, issued a statement highlighting the infrared observatory's top 15 discoveries.

  • Vita ignotum: How will NASA recognize life as we do not know it?

    Jason RhianJune 26th, 2018

    Since humanity realized that other worlds orbited distant stars, we have wondered what life on these far-flung planets might look like. While Star Trek and other series have depicted the life of these planets as, essentially, humans with bumpy heads - NASA is considering all the possibilities of what alien life might actually be like.

  • Exoplanet-hunting TESS spacecraft ready for launch

    CAPE CANAVERAL, Fla. — NASA and SpaceX are set to launch the Transiting Exoplanet Survey Satellite (TESS). If everything goes according to plan, the observatory will conduct a two-year mission to survey more than 85 percent of the sky, searching for exoplanets around bright stars in the 300-light-year distance range.

  • NASA telescopes discover water-rich exoplanet atmosphere

    Christopher PaulMarch 4th, 2018

    Scientists using NASA's Hubble and Spitzer space telescopes in concert have examined the elemental composition of a distant exoplanet's atmosphere in the highest detail yet. The planet, designated WASP-39b, is about the same mass as Saturn, but has three times as much water, according to NASA.

  • Artificial intelligence doesn’t find aliens – does find new exoplanets in old Kepler data

    Laurel KornfeldDecember 15th, 2017

    Contrary to what other outlets attempted to suggest, NASA did not announce it had discovered aliens. Rather, a computer trained to find exoplanets by identifying weak signals in data collected by NASA's Kepler mission discovered two new planets, each in multi-planet systems.
