    What's Up - February 2020

    Looking for astronomy highlights for February 2020? This month is the best time of the year to try to view Mercury, soon after sunset; Mars disappears behind the Moon on Feb. 18; and the bright red star on Orion’s shoulder, Betelgeuse, has been acting weird. (Or has it?)

    NASA's Spitzer Space Telescope: Unveiling the Universe

    NASA's Spitzer Space Telescope: Unveiling the Universe

    After 16 years of unveiling the infrared universe, NASA's Spitzer Space Telescope has left a singular legacy. As one of NASA’s four Great Observatories -- a series of powerful telescopes including Hubble, Chandra and Compton that can observe the cosmos in different parts of the electromagnetic spectrum --Spitzer quickly became a pioneer in the exploration of the worlds beyond our human vision. From stars being born to planets beyond our solar system (like the seven Earth-size planets around the star TRAPPIST-1), Spitzer's science discoveries will continue to inspire the world for many years to come.

    NASA's New Planet Tracker, NEID

    NASA's New Planet Tracker, NEID

    A new NASA-funded planet-hunting instrument has been installed on the WIYN telescope, on Arizona's Kitt Peak. NEID (pronounced NOO-id) is a spectrometer that is one of the first instruments of its kind with the precision to detect small, terrestrial planets around nearby stars. NEID will also confirm the presence of planets discovered by NASA's TESS space telescope, and reveal details of their anatomy.

    Eventually, scientists want to be able to find Earth-like planets around Sun-like stars, in an effort to find a world with life on it.

    First Drive Test of NASA’s Mars 2020 Rover

    First Drive Test of NASA’s Mars 2020 Rover

    On Dec. 17, 2019, engineers took NASA’s next Mars rover for its first spin. The test took place in the Spacecraft Assembly Facility clean room at NASA’s Jet Propulsion Laboratory in Pasadena, California. This was the first drive test for the new rover, which will move to Cape Canaveral, Florida, in the beginning of next year to prepare for its launch to Mars in the summer.
