This new image of the rose-coloured star forming region Messier 17 was captured by the Wide Field Imager on the MPG/ESO 2.2-metre telescope at ESO’s La Silla Observatory in Chile. It is one of the sharpest images showing the entire nebula and not only reveals its full size but also retains fine detail throughout the cosmic landscape of gas clouds, dust and newborn stars.
The nebula pictured here may have had more names bestowed upon it over the ages than any other object of its kind. Althou [...]
NASA and Orbital ATK of Promontory, Utah, are getting fired up for a second qualification ground test for the largest, most powerful boosters ever built for the agency’s new rocket, the Space Launch System (SLS).
On Sept. 22, engineers successfully tested the booster thrust vector control and avionics systems during an off-motor hot-fire test at ATK. The hot-fire test simulated the test cycle that will be used in the second qualification test, which will closely resemble flight conditions.
Does the Sun return to the same spot on the sky every day? No. A better and more visual answer to that question is an analemma, a composite image taken from the same spot at the same time over the course of a year. The featured weekly analemma was taken despite cold temperatures and high winds near the Concordia Station in Antarctica. The position of the Sun at 4 pm was captured on multiple days in the digital composite image, believed to be the first analemma constructed from Antarctica.
Crew members practiced an emergency evacuation drill and conducted long-term biomedical research today onboard the International Space Station. Japan’s fifth resupply ship is also being loaded with trash before its mission ends early next week.
Station Commander Scott Kelly teamed up with his fellow One-Year Crew member Mikhail Kornienko and cosmonaut Oleg Kononenko to review the procedures they would use to evacuate the station in the unlikely event of an emergency. Kelly then moved on to [...]
Cambridge, MA - The center of our Milky Way galaxy is a mysterious place. Not only is it thousands of light-years away, it's also cloaked in so much dust that most stars within are rendered invisible. Harvard researchers are proposing a new way to clear the fog and spot stars hiding there. They suggest looking for radio waves coming from supersonic stars.
"There's a lot we don’t know about the galactic center, and a lot we want to learn," says lead author Idan Ginsburg of the Harvard-Smiths [...]
The story of Galileo 5 and 6 and their journey to orbit... Day started with a comprehensive tour of the Guiana Space Centre, with a number of welcome speeches from representatives of those involved in the launch. We have …
There may be fewer pairs of supermassive black holes orbiting each other at the cores of giant galaxies than previously thought, according to a new study by astronomers who analyzed data from the National Science Foundation's Karl G. Jansky Very Large Array (VLA) radio telescope.
Massive galaxies harbor black holes with millions of times more mass than our Sun at their centers. When two such galaxies collide, their supermassive black holes join in a close orbital dance that ultimately results [...]
Japan’s resupply ship, the “Kounotori” HII Transfer Vehicle-5 (HTV-5), will end its stay at the International Space Station next Monday. A new Russian Progress cargo mission will launch to replenish the crew Oct. 1. While the HTV-5 is winding down its mission, the six-member Expedition 45 is conducting human research and lab maintenance.
First time space-flyers Kjell Lindgren from NASA and Yui Kimiya Yui from Japan checked each other’s eyes today for the Ocular Health study. Lindgren [...]
What are those streaks of light in the sky? First and foremost, the arching structure is the central band of our Milky Way galaxy. Visible in this galactic band are millions of distant stars mixed with numerous lanes of dark dust. Harder to discern is a nearly vertical beam of light rising from the horizon, just to the right of the image center.
This beam is zodiacal light, sunlight scattered by dust in our Solar System that may be surprisingly prominent just after sunset or just before sunr [...]
