Similar in size to large, bright spiral galaxies in our neighborhood, IC 342 is a mere 10 million light-years distant in the long-necked, northern constellation Camelopardalis. A sprawling island universe, IC 342 would otherwise be a prominent galaxy in our night sky, but it is hidden from clear view and only glimpsed through the veil of stars, gas and dust clouds along the plane of our own Milky Way galaxy.
Even though IC 342's light is dimmed by intervening cosmic clouds, this deep telesco [...]
Hubble Space Telescope astronomers are finding that the old adage "what goes up must come down" even applies to an immense cloud of hydrogen gas outside our Milky Way galaxy. The invisible cloud is plummeting toward our galaxy at nearly 700,000 miles per hour.
Though hundreds of enormous, high-velocity gas clouds whiz around the outskirts of our galaxy, this so-called "Smith Cloud" is unique because its trajectory is well known. New Hubble observations suggest it was launched from the outer r [...]
Today, NASA remembers the sacrifice of the crews of Apollo 1 and space shuttles Columbia and Challenger. Mission Control Center in Houston and the crew aboard the International Space Station observed a moment of silence and Commander Scott Kelly sent down a few words memorializing the lost astronauts.
The six residents aboard the space station kept up their pace with spacewalk preparations, Cygnus cargo transfers and advanced space science. The orbital laboratory also completed two of a serie [...]
Giant elliptical galaxy M60 and spiral galaxy NGC 4647 do look like an odd couple in this sharp cosmic portrait from the Hubble Space Telescope. But they are found in a region of space where galaxies tend to gather, on the eastern side of the nearby Virgo Galaxy Cluster. About 54 million light-years distant, bright M60's simpler egg-like shape is created by its randomly swarming older stars, while NGC 4647's young blue stars, gas and dust are organized into winding arms rotating in a flattened d [...]
Arianespace kicked off its fast-paced 2016 operational schedule tonight with the 70th consecutive launch success using Ariane 5, which orbited a pioneering new-generation satellite for this workhorse vehicle’s leading commercial customer.
Lifting off exactly on time from the Spaceport’s ELA-3 launch zone in French Guiana, Ariane 5 released Intelsat 29e – international operator Intelsat’s milestone first high-throughput EpicNG-series spacecraft – into geostationary transfer orbit af [...]
