This image of comet 67P/Churyumov-Gerasimenko, taken by Rosetta's Optical, Spectroscopic, and Infrared Remote Imaging System (OSIRIS) on Sept. 20, from a distance of 4.5 miles (7.2 kilometers), shows jets of dust and gas streaming into space from the neck of the comet's nucleus.
Images of the comet nucleus, taken by Rosetta earlier in the summer, showed that the distinct jets of dust and gas emanating from the comet were originated from the neck region, which connects the comet's two lobes. [...]
A New Moon joined giant sunspot group AR 2192 to dim the bright solar disk during Thursday's much anticipated partial solar eclipse. Visible from much of North America, the Moon's broad silhouette is captured in this extreme telephoto snapshot near eclipse maximum from Santa Cruz, California.
About the size of Jupiter, the remarkable AR 2192 itself darkens a noticeable fraction of the Sun, near center and below the curved lunar limb. As the sunspot group slowly rotates across the Sun and out [...]
The highway traffic to and from the International Space Station gets busy Saturday and the six crew members of Expedition 41 are working feverishly to manage the traffic flow.
Final packing of the commercial Space Exploration Technologies Corp (SpaceX) Dragon was completed and the hatch closed ahead of Saturday’s unberthing and departure. Release is planned for 9:56 a.m. EDT and splashdown in the Pacific Ocean west of Baja California is scheduled for about 3:30 p.m.
While the crew comple [...]
NASA scientists have identified an unexpected high-altitude methane ice cloud on Saturn's moon Titan that is similar to exotic clouds found far above Earth's poles.
This lofty cloud, imaged by NASA's Cassini spacecraft, was part of the winter cap of condensation over Titan's north pole. Now, eight years after spotting this mysterious bit of atmospheric fluff, researchers have determined that it contains methane ice, which produces a much denser cloud than the ethane ice previously identified [...]
The Orb-3 mission’s payload fairing (essentially the casing around the spacecraft) was installed on Orbital Sciences Corp.’s Antares rocket the evening of Oct. 23, 2014, at the Horizontal Integration Facility at NASA’s Wallops Flight Facility in Virginia.
The rocket is scheduled to roll out to Mid-Atlantic Regaional Spaceport Pad 0A at Wallops late in the afternoon on Oct. 24 in preparation for launch Monday, Oct. 27, at 6:45 p.m. EDT.
This mission is the third of eight Orbital fl [...]
A partial solar eclipse was visible from much of North America before sundown on Thursday, Oct.23. A partial eclipse occurs when the moon blocks a portion of the Sun from view.
The Hinode spacecraft captured images of yesterday’s eclipse as it passed over North America using its X-ray Telescope. During the eclipse, the new moon eased across the Sun from right to left with the Sun shining brilliantly in the background. And as a stroke of good luck, this solar cycle’s largest active reg [...]
This neat little galaxy is known as NGC 4526. Its dark lanes of dust and bright diffuse glow make the galaxy appear to hang like a halo in the emptiness of space in this image from the NASA/ESA Hubble Space Telescope.
Although this image paints a picture of serenity, the galaxy is anything but. It is one of the brightest lenticular galaxies known, a category that lies somewhere between spirals and ellipticals. It has hosted two known supernova explosions, one in 1969 and another in 1994, and [...]
MOSCOW - China has launched an unmanned spacecraft, named Chang’e-5, on Friday, with hopes the probe will carry out the country’s first mission to the Moon and back, CCTV reported.
The mission is aimed at testing technologies which are vital for the success of the country’s first lunar mission which will return to the Earth.
The launch of Chang’e-5 took place at 18:00 UTC. The lunar orbiter was carried by an advanced Long March-3C launch vehicle from the LC2 launch complex of the X [...]
As you (safely!) watched the progress of yesterday's partial solar eclipse, you probably also spotted a giant sunspot group. Captured in this sharp telescopic image from October 22nd the complex AR 2192 is beautiful to see, a sprawling solar active region comparable in size to the diameter of Jupiter.
Like other smaller sunspot groups, AR 2192 is now crossing the Earth-facing side of the Sun and appears dark in visible light because it is cooler than the surrounding surface. Still, the energ [...]
