The Great Nebula in Orion, an immense, nearby starbirth region, is probably the most famous of all astronomical nebulas. Here, filaments of dark dust and glowing gas surround hot young stars at the edge of an immense interstellar molecular cloud only 1500 light-years away. In the featured deep image shown in assigned colors, part of the nebula's center is shown as taken by the Hubble Space Telescope.
The Great Nebula in Orion can be found with the unaided eye near the easily identifiable bel [...]
NASA is preparing for longer human journeys deeper into space and is exploring how to keep astronauts healthy and productive. The Expedition 50 crew members today studied space nutrition, measured their bodies and checked their eyes to learn how to adapt to living in space. The space residents also unloaded a cargo ship, worked on the Tranquility module and practiced an emergency simulation.
The ongoing Energy experiment that ESA astronaut Thomas Pesquet collected urine samples for today seek [...]
Why does this galaxy spin so fast? To start, even identifying which type of galaxy UGC 12591 is difficult -- it has dark dust lanes like a spiral galaxy but a large diffuse bulge of stars like a lenticular. Surprisingly observations show that UGC 12591 spins at about 480 km/sec, almost twice as fast as our Milky Way, and the fastest rotation rate yet measured. The mass needed to hold together a galaxy spinning this fast is several times the mass of our Milky Way Galaxy.

After lifting off from the Spaceport, Vega deployed its Sentinel-2B passenger into Sun-synchronous orbit for a mission to monitor land masses and coastal zones around the world.
Continuing Vega’s track record of success, Arianespace’s ninth flight with the lightweight launcher delivered Europe’s Sentinel-2B Earth observation satellite to orbit tonight during a mission performed from the Spaceport in French Guiana.
This was the ninth consecutive on-target launch with Vega since its i [...]
Four CubeSats were deployed this morning as the crew researched fluid shifts toward the head that may affect astronaut vision. Tools were also being collected and organized today ahead of possible maintenance spacewalks.
Four CubeSats were ejected Monday morning from outside Japan’s Kibo lab module using the NanoRacks CubeSat Deployer. The LEMUR-2 satellites will help monitor global ship tracking and improve weather forecasting.
Sergey Ryzhikov from Roscosmos participated in ultrasound s [...]
