NASA’s Hubble Space Telescope has picked up the faint, ghostly glow of stars ejected from ancient galaxies that were gravitationally ripped apart several billion years ago. The mayhem happened 4 billion light-years away, inside an immense collection of nearly 500 galaxies nicknamed “Pandora’s Cluster,” also known as Abell 2744.
The scattered stars are no longer bound to any one galaxy, and drift freely between galaxies in the cluster. By observing the light from the orphaned stars, Hu [...]
As it soared past Saturn's large moon Titan recently, NASA's Cassini spacecraft caught a glimpse of bright sunlight reflecting off hydrocarbon seas.
In the past, Cassini had captured, separately, views of the polar seas and the sun glinting off them, but this is the first time both have been seen together in the same view.
Also in the image:

Some elements of a rocket can be familiar, like the boosters and engines. But there are several important parts on NASA's new rocket, the Space Launch System (SLS), that may be less widely known. Case in point? The interim cryogenic propulsion stage (ICPS).
If the SLS was dissected, the ICPS lies just below the Orion capsule, at the top of the SLS. The ICPS is a liquid oxygen/liquid hydrogen-based system. On the first test mission of Orion and SLS together, called Exploration Mission-1, the [...]

This Chandra X-ray Observatory image of the Hydra A galaxy cluster was taken on Oct. 30, 1999, with the Advanced CCD Imaging Spectrometer (ACIS) in an observation that lasted about six hours. Hydra A is a galaxy cluster that is 840 million light years from Earth.
The cluster gets its name from the strong radio source, Hydra A, that originates in a galaxy near the center of the cluster. Optical observations show a few hundred galaxies in the cluster. Chandra X-ray observations reveal a large [...]
Many Interacting Worlds theory challenges foundations of quantum science.
Griffith University academics are challenging the foundations of quantum science with a radical new theory based on the existence of, and interactions between, parallel universes.
In a paper published in the prestigious journal Physical Review X, Professor Howard Wiseman and Dr Michael Hall from Griffith's Centre for Quantum Dynamics, and Dr Dirk-Andre Deckert from the University of California, take interacting paral [...]
MOSCOW - A Meridian communications satellite has been put into orbit by a Soyuz-2.1a carrier rocket, launched from Russia's Plesetsk space center, the Defense Ministry's spokesperson told RIA Novosti Thursday.
"The Soyuz-2.1a carrier-rocket, launched Thursday, has successfully put the Meridian satellite into orbit," Col. Alexei Zolotukhin, a spokesperson for Russia's Aerospace Defense Forces said.
This is the seventh Meridian satellite put into orbit. Two of the previous six launches were [...]
Fourth Global Positioning System Satellite Launched for the Air Force in 2014.
United Launch Alliance Atlas V blasts off with the GPS IIF-8 mission for the U.S. Air ForceCape Canaveral Air Force Station, Fla., (Oct. 29, 2014) – A United Launch Alliance (ULA) Atlas V rocket successfully launched the eighth Global Positioning System (GPS) IIF-8 satellite for the U.S. Air Force at 1:21 p.m. EDT today from Space Launch Complex-41. This is ULA’s 12th launch in 2014, and the 89th successful lau [...]
Frightening forms and scary faces are a mark of the Halloween season. They also haunt this cosmic close-up of the eastern Veil Nebula. The Veil Nebula itself is a large supernova remnant, the expanding debris cloud from the death explosion of a massive star.
While the Veil is roughly circular in shape and covers nearly 3 degrees on the sky in the constellation Cygnus, this portion of the eastern Veil spans only 1/2 degree, about the apparent size of the Moon. That translates to 12 light-year [...]
The Wallops Incident Response Team completed today an initial assessment of Wallops Island, Virginia, following the catastrophic failure of Orbital Science Corp.’s Antares rocket shortly after liftoff at 6:22 p.m. EDT Tuesday, Oct. 28, from Pad 0A of the Mid-Atlantic Regional Spaceport at NASA’s Wallops Flight Facility in Virginia.
“I want to praise the launch team, range safety, all of our emergency responders and those who provided mutual aid and support on a highly-professional respo [...]
Traveling about 261 miles over the Atlantic Ocean, the unpiloted ISS Progress 57 Russian cargo ship docked at 9:08 a.m. EDT to the Pirs Docking Compartment of the International Space Station.
The craft is delivering almost three tons of food, fuel and supplies, including 1,940 pounds of propellant; 48 pounds of oxygen; 57 pounds of air; 926 pounds of water; and 2,822 pounds of spare parts, supplies and experiment hardware for the six members of the Expedition 41 crew currently living and work [...]
NASA astronaut Reid Wiseman posted this image of a sunrise, captured from the International Space Station, to social media on Oct. 29, 2014. Wiseman wrote, "Not every day is easy. Yesterday was a tough one. #sunrise"
Wiseman was referring to the loss on Oct. 28 of the Orbital Sciences Corporation Antares rocket and Cygnus spacecraft, moments after launch at NASA's Wallops Flight Facility in Virginia. The Cygnus spacecraft was filled with about 5,000 pounds of supplies slated for the Internati [...]
