NASA Awards Engineering Services and Science Capability Contract
NASA has selected Jacobs Technology of Tullahoma, Tennessee, to provide a broad spectrum of engineering and scientific support services at Marshall Space Flight Center in Huntsville, Alabama and the Michoud Assembly Facility in New Orleans.
Nejdetailnější snímek povrchu hvězdy a její atmosféry
Astronomům se s použitím interferometru ESO/VLTI podařilo získat dosud nejdetailnější snímek cizí hvězdy – rudého veleobra Antares. Pozorování jim rovněž umožnilo vytvořit první mapu zachycující rychlost pohybu hmoty v atmosféře jiné hvězdy, než je naše Slunce. Mapa odhalila nečekané turbulence v rozsáhlé atmosféře Antara. Výsledky byly publikovány ve vědeckém časopise Nature.
Best Ever Image of a Star’s Surface and Atmosphere
Using ESO’s Very Large Telescope Interferometer astronomers have constructed the most detailed image ever of a star — the red supergiant star Antares. They have also made the first map of the velocities of material in the atmosphere of a star other than the Sun, revealing unexpected turbulence in Antares’s huge extended atmosphere. The results were published in the journal Nature.
NASA Astronauts Available for Interviews Before Space Station Mission
NASA astronauts Mark Vande Hei and Joe Acaba, who are making final preparations for a Sept. 12 launch to the International Space Station, will be available for live satellite interviews at 7 and 9 a.m. EDT, respectively, on Friday, Sept. 1.
Solar spectacular seen from Earth and space
While ground-based observers experienced the awe-inspiring view of a total solar eclipse yesterday, astronauts aboard the International Space Station, and our Sun-watching satellites, enjoyed unique perspectives of this spectacular sight from space.

NASA Successfully Launches Latest Communications Satellite
NASA’s Tracking and Data Relay Satellite-M (TDRS-M), which is the third and final in a series of next generation communications satellites, has successfully been placed into orbit following separation from an United Launch Alliance (ULA) Atlas V rocket.
Sentinel-1 speeds up crop insurance payouts
For the first time in India, a state government is using satellites to assess lost crops so that farmers can benefit from speedy insurance payouts.
ESA’s Proba-3 will create artificial solar eclipses
Astrophysicists are joining sightseers in watching Monday’s total solar eclipse across North America but, in the decade to come, they will be viewing eclipses that last for hours instead of a few minutes – thanks to a pioneering ESA space mission.
Superhmotná černá díra požírá kosmickou medúzu
Pozorování takzvaných 'medúzovitých galaxií' pomocí dalekohledu ESO/VLT odhalila dosud neznámý způsob, jakým superhmotné černé díry získávají hmotu. Zdá se, že mechanismus vzniku struktur tvořených plynem i hvězdami a připomínajících chapadla medúzy, které daly těmto objektům jméno, rovněž umožňuje, aby se plyn dostal až do centrální oblasti galaxie, stal se kořistí černé díry a jasně se rozzářil. Výsledky byly publikovány ve vědeckém časopise Nature.
Supermassive Black Holes Feed on Cosmic Jellyfish
Observations of “Jellyfish galaxies” with ESO’s Very Large Telescope have revealed a previously unknown way to fuel supermassive black holes. It seems the mechanism that produces the tentacles of gas and newborn stars that give these galaxies their nickname also makes it possible for the gas to reach the central regions of the galaxies, feeding the black hole that lurks in each of them and causing it to shine brilliantly. The results appeared today in the journal Nature.
2017 Astronaut Candidates Available for Interviews Before Training
NASA’s newest astronaut candidates, a diverse dozen women and men, will participate in media interviews and a final news conference before training on Tuesday, Aug. 22, at the agency’s Johnson Space Center in Houston.

NASA has awarded the Kennedy Infrastructure, Applications and Communication (KIAC) contract to ASRC Federal Data Solutions, LLC of Beltsville, Maryland.
NASA Awards Contract to Extend Operations of Research, Development Center
NASA has awarded a contract to the California Institute of Technology (Caltech) in Pasadena, California, to extend operations of the agency’s Jet Propulsion Laboratory (JPL), also in Pasadena, through Sept. 30, 2018.
NASA Television to Air Launch of Next Communications Satellite
NASA is targeting 8:03 a.m. EDT Friday, Aug. 18, for the launch of its next Tracking and Data Relay Satellite (TDRS) mission atop a United Launch Alliance Atlas V rocket from Cape Canaveral Air Force Station in Florida. The launch, and related activities that begin Thursday, Aug. 17, will air live on NASA Television and the agency’s website.

Tracking a solar eruption through the Solar System
Ten spacecraft, from ESA’s Venus Express to NASA’s Voyager-2, felt the effect of a solar eruption as it washed through the Solar System while three Earth-orbiting satellites watched, providing a unique perspective on this space weather event.
