NASA's Goddard Space Flight Center 13 Mar 2018, 17:00 UTC Though once big enough to swallow three Earths with room to spare, Jupiter’s Great Red Spot has been shrinking for a century and a half. Nobody is sure how long the storm will continue to contract or whether it will disappear altogether.
NASA's Goddard Space Flight Center 12 Mar 2018, 18:00 UTC Astronomers have put NASA's Hubble Space Telescope on an Indiana Jones-type quest to uncover an ancient "relic galaxy" in our own cosmic backyard. The very rare and odd assemblage of stars has remained essentially unchanged for the past 10 billion years. This wayward stellar island provides valuable new insights into the origin and evolution of galaxies billions of years ago.
NASA: Kepler News and Features 9 Mar 2018, 18:46 UTC The seventeenth observing campaign of the Kepler spacecraft’s K2 extended mission is now underway. The cartoon illustrates some of the objects of interest that Kepler is observing for 68 days, from Mar. 1 to May 8, 2018. The campaign has prospects for discoveries among more 30,000 objects in the direction of the constellation Virgo.
NASA's Goddard Space Flight Center 9 Mar 2018, 15:56 UTC This enchanting spiral galaxy can be found in the constellation of Ursa Major (the Great Bear). Star-studded NGC 3972 lies about 65 million light-years away from Earth, meaning that the light that we see now left it 65 million years ago, just when the dinosaurs became extinct. NGC 3972 has had its fair share of dramatic events. In 2011 astronomers observed the explosion of a Type Ia supernova in the galaxy (not visible in this image). These dazzling objects all peak at the same brightness, and are brilliant enough to be seen over large distances.
ESA Top News 9 Mar 2018, 10:00 UTC Europe’s first mission to Mercury will soon be ready for shipping to the spaceport to begin final preparations for launch. The mission passed a major review yesterday, meaning that the three BepiColombo spacecraft, along with ground equipment and mission experts, are confirmed to start the move from ESA’s centre in the Netherlands to Europe’s Spaceport in Kourou, French Guiana at the end of next month. The launch window is open from 5 October until 29 November.
NASA: Kepler News and Features 7 Mar 2018, 22:43 UTC Capturing images of our home planet from the perspective of faraway spacecraft has become a tradition at NASA, ever since Voyager, 28 years ago, displayed our “pale blue dot” in the vastness of space. But the view of Earth from NASA’s Kepler Space Telescope is quite something else. This Kepler image of Earth was recently beamed back home. Captured on Dec. 10, 2017 after the spacecraft adjusted its telescope to a new field of view, Earth’s reflection as it slipped past was so extraordinarily bright that it created a saber-like saturation bleed across the instrument’s sensors, obscuring the neighboring Moon.
NASA's Jet Propulsion Laboratory News and Features 7 Mar 2018, 18:18 UTC Data collected by NASA's Juno mission to Jupiter indicate that the atmospheric winds of the gas-giant planet run deep into its atmosphere and last longer than similar atmospheric processes found here on Earth. The findings will improve understanding of Jupiter's interior structure, core mass and, eventually, its origin.
