CAPE CANAVERAL AIR FORCE STATION, Fla. -- The U.S. Air Force’s 45th Space Wing supported SpaceX’s successful launch of the EchoStar XXIII spacecraft aboard a Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center March 16 at 2 a.m. EDT.
EchoStar 23, designed and built by Space Systems Loral for EchoStar Corporation, will provide television broadcast services over Brazil with an estimated service life of 15 years.
This launch marks the last SpaceX Falcon 9 launch [...]
A recent NASA-funded study has shown how the hydrocarbon lakes and seas of Saturn's moon Titan might occasionally erupt with dramatic patches of bubbles.
For the study, researchers at NASA's Jet Propulsion Laboratory in Pasadena, California, simulated the frigid surface conditions on Titan, finding that significant amounts of nitrogen can be dissolved in the extremely cold liquid methane that rains from the skies and collects in rivers, lakes and seas. They demonstrated that slight changes in [...]
Peering from the shadows, the Saturn-facing hemisphere of Mimas lies in near darkness alongside a dramatic sunlit crescent. The mosaic was captured near the Cassini spacecraft's final close approach on January 30, 2017. Cassini's camera was pointed in a nearly sunward direction only 45,000 kilometers from Mimas. The result is one of the highest resolution views of the icy, crater-pocked, 400 kilometer diameter moon.
An enhanced version better reveals the Saturn-facing hemisphere of the synch [...]
VLT observations of distant galaxies suggest they were dominated by normal matter.
New observations indicate that massive, star-forming galaxies during the peak epoch of galaxy formation, 10 billion years ago, were dominated by baryonic or “normal” matter. This is in stark contrast to present-day galaxies, where the effects of mysterious dark matter seem to be much greater. This surprising result was obtained using ESO’s Very Large Telescope and suggests that dark matter was less influe [...]
Cambridge, MA - A massive protostar, still cradled within its tightly packed star-forming cloud, recently roared to life, shining 70 times brighter than before and warming the surrounding dust of its stellar nursery. This sudden outburst was likely triggered by an avalanche of star-forming gas crashing onto the surface of the star.
A team of astronomers made this discovery by comparing new observations from the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile with earlier observat [...]
Stars are forming in the gigantic dust pillar called the Cone Nebula. Cones, pillars, and majestic flowing shapes abound in stellar nurseries where natal clouds of gas and dust are buffeted by energetic winds from newborn stars. The Cone Nebula, a well-known example, lies within the bright galactic star-forming region NGC 2264. The Cone was captured in unprecedented detail in this close-up composite of several observations from the Earth-orbiting Hubble Space Telescope.
While the Cone Nebula [...]
