NASA's Goddard Space Flight Center 18 Sep 2017, 14:00 UTC At more than 10 billion miles away from Earth, there is no day and night. Time and space are fathomless and our Sun is a distant point of starlight — a faint reminder of the home NASA’s twin Voyagers, humanity’s farthest and longest-lived spacecraft, left behind 40 years ago. Voyager 1, which launched on Sept. 5, 1977, and Voyager 2, launched on Aug. 20, 1977, continue to return data that shape our view and understanding of our place in the universe.
ESA Top News 18 Sep 2017, 10:00 UTC This delicate image showing the intricacies of interstellar bubbles and wisps reveals great turmoil in the W3/W4/W5 complex of molecular clouds and star-forming regions. It was taken by ESA’s Herschel Space Observatory, a trailblazing mission that observed the sky in far-infrared and submillimetre wavelengths between 2009 and 2013.
NASA's Goddard Space Flight Center 15 Sep 2017, 14:09 UTC This Hubble Space Telescope picture shows NGC 5398, a barred spiral galaxy located about 55 million light-years away.
NASA Breaking News 15 Sep 2017, 12:00 UTC A thrilling epoch in the exploration of our solar system came to a close today, as NASA's Cassini spacecraft made a fateful plunge into the atmosphere of Saturn, ending its 13-year tour of the ringed planet.
NASA's Ames Research Center News and Features 15 Sep 2017, 10:34 UTC On September 15, a month before the twentieth anniversary of its launch on October 15, 1997, NASA’s Cassini spacecraft will plunge into Saturn’s atmosphere in the conclusion of 13 years of exploration of Saturn, its rings and moons.
National Radio Astronomy Observatory (NRAO) 14 Sep 2017, 19:11 UTC The National Radio Astronomy Observatory (NRAO) and Associated Universities, Inc. (AUI) are launching a new initiative to design a next-generation radio telescope with scientific capabilities far beyond those provided by any existing or currently proposed observatory. Building on the success of one of the National Science Foundation’s (NSF) flagship observatories, the Karl G. Jansky Very Large Array (VLA), NRAO and AUI are beginning a two-year project to explore the science opportunities, design concepts, and technologies needed to construct a new class of radio telescope. This proposed array, consisting of more than 200 antennas, would extend across the desert southwest of the United States and into northern Mexico.
Hubble Space Telescope News 14 Sep 2017, 14:00 UTC Astronomers have discovered that the well-studied exoplanet WASP-12b reflects almost no light, making it appear essentially pitch black. This discovery sheds new light on the atmospheric composition of the planet and also refutes previous hypotheses about WASP-12b’s atmosphere. The results are also in stark contrast to observations of another similarly sized exoplanet.
NASA's Goddard Space Flight Center 14 Sep 2017, 12:38 UTC Using the RELL instruments, operators successfully located a small leak from the station’s ammonia coolant loop, and confirmed that it was not a safety concern. Later they were able to return and more precisely characterize the leak. This valuable data helped station operators vent and isolate the leaking line from the coolant loop and successfully stop the leak.
