A Delta IV Heavy rocket lifts off from Space Launch Complex 37 at Cape Canaveral Air Force Station carrying NASA’s Orion spacecraft on an unpiloted flight test to Earth orbit. Liftoff was at 7:05 a.m. EST. During the two-orbit, four-and-a-half hour mission, engineers will evaluate the systems critical to crew safety, the launch abort system, the heat shield and the parachute system.
After a 10 year journey Comet 67P/Churyumov-Gerasimenko and the Rosetta Spacecraft dance together before Rosetta releases Philae for the first soft landing on a comet. According to ESA the Rosetta spacecraft will deploy the Philae lander on 12 November at 08:35 UTC. A confermation of landing is expected at 16:00 UTC.

The massive galaxy cluster Abell 2744, nicknamed Pandora’s Cluster, takes on a ghostly look in this Hubble Space Telescope view where the total starlight from the cluster has been artificially colored blue. This plot reveals that not all the starlight is contained within the cities of stars — the galaxies — which appear as bright blue-white blobs. A fraction of the starlight is dispersed throughout the cluster, as seen in the darker blue regions. This light comes from “dead” galaxies. The galaxies were torn apart long ago by the cluster’s gravitational forces, and their stars were scattered into “intracluster” space — the space between the galaxies. These orphaned stars roam the cluster, without being gravitationally tethered to any single galaxy. Because these extremely faint stars are brightest at near-infrared wavelengths of light, this type of observation could only be accomplished with Hubble’s infrared sensitivity to extraordinarily dim light.
The galaxies that are not colored blue lay either in the foreground or background and are not part of the cluster.
The intracluster light was detected as part of the Frontier Fields program, an ambitious three-year effort, begun in 2013, that teams Hubble with NASA’s other Great Observatories — the Spitzer Space Telescope and the Chandra X-ray Observatory — to probe the early universe by studying large galaxy clusters. Abell 2744 resides about 3.5 billion light-years away.
Hubble treats astronomers to gorgeous close-up views of the eerie outer planets. But it’s a bit of a trick when it seems like the planet’s looking back at you! This happened on April 21, 2014, when Hubble was being used to monitor changes in Jupiter’s immense Great Red Spot (GRS) storm. During the exposures, the shadow of the Jovian moon Ganymede swept across the center of the GRS. This gave the giant planet the uncanny appearance of having a pupil in the center of a 10,000-mile-diameter “eye.” Momentarily, Jupiter took on the appearance of a Cyclops planet! The shadows from Jupiter’s four major satellites routinely cross the face of Jupiter. This natural-color picture was taken with Hubble’s Wide Field Camera 3.
Hi, I’m Carolyn Collins Petersen. October has many good sky-gazing objects to see – from planets to a pair of eclipses and a meteor shower to some favorite constellations and deep-sky objects. Grab your binoculars or small telescope, so click Play to get started!

Every month is a great month to go out and explore the stars and planets starting a couple of hours after sunset. Carolyn Collins Petersen, is your guide to skygazing for August 2014. This month you can see gorgeous planets, and some familiar constellations. Be sure and dress for the weather, and bring along binoculars or a small telescope to enhance your view.
Seven thousand years ago, a star like the Sun, that had swollen up to become a red giant, began its final transformation to become a white dwarf. Its outer atmosphere, was speeding away to space, and formed shells of gas and dust. In the center lay, and its light heated up the shells, causing them to glow. Today, from a distance of twenty-three hundred light years, this is what we see in our sky, leftover from that long-ago event. It’s called the Ring Nebula. Hi, I’m Carolyn Collins Petersen, and this month, I’ll show you how to find this object, a famous southern-hemisphere globular cluster, four planets, and a lot more. Let’s get started!
Hi, I’m Carolyn Collins Petersen, your guide to the starry skies of July. This month is mid-summer for northern hemisphere viewers, while observers in the southern hemisphere are observing winter skies. As you stargaze, bring along binoculars or a small telescope to help enhance your view.
