Universities Space Research Association 11 Feb 2019, 13:42 UTC Researchers using NASA’s SOFIA airborne telescope have found that cosmic dust, a building block of planets, forms in the wake of a supernova blast wave.
ESA Top News 7 Feb 2019, 15:00 UTC ESA’s Gaia satellite has looked beyond our Galaxy and explored two nearby galaxies to reveal the stellar motions within them and how they will one day interact and collide with the Milky Way – with surprising results.
HubbleSite NewsCenter -- Latest News Releases 7 Feb 2019, 15:00 UTC The two major planets beyond Saturn have only been visited once by a spacecraft, albeit briefly. NASA's Voyager 2 spacecraft swung by Uranus in 1986, and Neptune in 1989. Our robotic deep-space tourist snapped the only close-up, detailed images of these monstrous worlds. For Neptune, the images revealed a planet with a dynamic atmosphere with two mysterious dark vortices. Uranus, however, appeared featureless. But these views were only brief snapshots. They couldn't capture how the planets' atmospheres change over time, any more than a single snapshot of Earth could tell meteorologists about weather behavior. And, they go through protracted seasonal changes in their multi-decades-long orbits. Ever since the Voyager encounter, the Hubble Space Telescope has provided an opportunity to monitor these worlds like a diligent weatherman.
ESA Top News 7 Feb 2019, 07:55 UTC The ExoMars rover that will search for the building blocks of life on the Red Planet has a name: Rosalind Franklin. The prominent scientist behind the discovery of the structure of DNA will have her symbolic footprint on Mars in 2021.
NASA's Goddard Space Flight Center 6 Feb 2019, 18:00 UTC On Jan. 3, 2019, the Chinese spacecraft Chang'e 4 safely landed on the floor of the Moon’s Von Kármán crater (186 kilometer diameter, 116 miles). Four weeks later (Jan. 30, 2019), as NASA’s Lunar Reconnaissance Orbiter approached the crater from the east, it rolled 70 degrees to the west to snap this spectacular view looking across the floor toward the west wall. Because LRO was 330 kilometers (205 miles) to the east of the landing site, the Chang'e 4 lander is only about two pixels across (bright spot between the two arrows), and the small rover is not detectable. The massive mountain range in the background is the west wall of Von Kármán crater, rising more than 3,000 meters (9,850 feet) above the floor.
NASA: Kepler News and Features 6 Feb 2019, 15:00 UTC NASA’s Kepler space telescope may be retired, but the discoveries continue to rack up for this historic planet-hunting mission. Kepler rang in the new year with several new planet discoveries, including a previously overlooked planet of an unusual size, as well as a super Earth and a Saturn-sized world orbiting a Sun-like star. In the meantime, the Kepler mission has released its final record of the spacecraft’s full field of view before the depletion of fuel permanently ended its work. NASA retired the spacecraft on Oct. 30, 2018, to a safe orbit.
NASA's Jet Propulsion Laboratory News and Features 5 Feb 2019, 17:52 UTC Explore the plethora of planets outside our solar system with new multimedia experiences from NASA's Exoplanet Exploration Program (ExEP). In addition to a new Exoplanet Travel Bureau poster celebrating a molten world called 55 Cancri e, space fans can enjoy a 360-degree visualization of the surface of the same planet, a multimedia journey into the life and death of planetary systems, and a major update to the popular Eyes on Exoplanets app.
