NASA's Goddard Space Flight Center 13 Oct 2017, 15:27 UTC As far as galaxies are concerned, size can be deceptive. Some of the largest galaxies in the Universe are dormant, while some dwarf galaxies, such as ESO 553-46 imaged here by the NASA/ESA Hubble Space Telescope, can produce stars at a hair-raising rate. In fact, ESO 553-46 has one of the highest rates of star formation of the 1,000 or so galaxies nearest to the Milky Way. No mean feat for such a diminutive galaxy!
Universities Space Research Association 12 Oct 2017, 18:06 UTC A team of scientists from Universities Space Research Association (USRA), NASA, NOAA and National Center for Atmospheric Research (NCAR) announced today the results of their research on how the ocean and land carbon cycle responded during the 2015-16 El Niño.
Max Planck Institute for Radio Astronomy 12 Oct 2017, 12:05 UTC Astronomers from the Max Planck Institute for Radio Astronomy in Bonn, Germany, and the Harvard-Smithsonian Center for Astrophysics have directly measured the distance to a star-forming region on the opposite side of our Milky Way Galaxy from the Sun, using the Very Long Baseline Array. Their achievement reaches deep into the Milky Way’s terra incognita and nearly doubles the previous record for distance measurement within our Galaxy.
Max Planck Institute for Astronomy 12 Oct 2017, 06:00 UTC Galaxies are majestic, rotating wheels of stars? Not in the case of the spindle-like galaxies studied by Athanasia Tsatsi (Max Planck Institute for Astronomy) and her colleagues. Using the CALIFA survey, the astronomers found that these slender galaxies, which rotate along their longest axis, are much more common than previously thought. The new data allowed the astronomers to create a model for how these unusual galaxies probably formed, namely out of a special kind of merger of two spiral galaxies. The results have been published in the journal Astronomy & Astrophysics.
NASA's Jet Propulsion Laboratory News and Features 11 Oct 2017, 21:53 UTC As NASA's Cassini spacecraft made its fateful dive into the upper atmosphere of Saturn on Sept. 15, the spacecraft was live-streaming data from eight of its science instruments, along with readings from a variety of engineering systems. While analysis of science data from the final plunge will take some time, Cassini engineers already have a pretty clear understanding of how the spacecraft itself behaved as it went in. The data are useful for evaluating models of Saturn's atmosphere the team used to predict the spacecraft's behavior at mission's end, and they help provide a baseline for planning future missions to Saturn.

NASA's Jet Propulsion Laboratory News and Features 10 Oct 2017, 20:25 UTC On Oct. 12 EDT (Oct. 11 PDT), a small asteroid designated 2012 TC4 will safely pass by Earth at a distance of approximately 26,000 miles (42,000 kilometers). This is a little over one tenth the distance to the Moon and just above the orbital altitude of communications satellites. This encounter with TC4 is being used by asteroid trackers around the world to test their ability to operate as a coordinated international asteroid warning network.
ESA Top News 10 Oct 2017, 07:46 UTC Talk about an image making your head spin: ESA astronaut Paolo Nespoli took this stunning image of NASA astronauts Randy Bresnik and Mark Vande Hai during last week’s spacewalk. During this excursion, the duo replaced part of the Station’s Canadarm2 robotic arm. The spacewalk took just under seven hours and saw the astronauts not only complete their main task but also accomplish some ‘get-ahead’ tasks. Spacewalks are intensive for both crewmembers and ground support, so any opportunity to get ahead is welcomed.
