Two spaceships are racing to the International Space Station this weekend. One is delivering about 2,400 kilograms of crew supplies and science gear and another is carrying three new crew members.
The Soyuz MS-02 spacecraft launched from the Baikonur Cosmodrome early Wednesday and will dock to the International Space Station Friday morning. Expedition 49-50 crew members Shane Kimbrough, Andrey Borisenko and Sergey Ryzhikov will enter the Poisk module to begin their mission and live and work i [...]
NASA's Juno spacecraft entered safe mode Tuesday, Oct. 18 at about 10:47 p.m. PDT (Oct. 19 at 1:47 a.m. EDT). Early indications are a software performance monitor induced a reboot of the spacecraft's onboard computer. The spacecraft acted as expected during the transition into safe mode, restarted successfully and is healthy. High-rate data has been restored, and the spacecraft is conducting flight software diagnostics. All instruments are off, and the planned science data collection for today's [...]
Framing a bright emission region this telescopic view looks out along the plane of our Milky Way Galaxy toward the nebula rich constellation Cygnus the Swan. Popularly called the Tulip Nebula, the glowing cloud of interstellar gas and dust is also found in the 1959 catalog by astronomer Stewart Sharpless as Sh2-101. About 8,000 light-years distant and 70 light-years across the complex and beautiful nebula blossoms at the center of the composite image.
Red, green, and blue hues map emission f [...]
Astronomers have found a pair of extraordinary cosmic objects that dramatically burst in X-rays. This discovery, obtained with NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton observatory, may represent a new class of explosive events found in space.
The mysterious X-ray sources flare up and become about a hundred times brighter in less than a minute, before returning to original X-ray levels after about an hour. At their peak, these objects qualify as ultraluminous X-ray sources (UL [...]
Have you ever seen the Pleiades star cluster? Even if you have, you probably have never seen it as dusty as this. Perhaps the most famous star cluster on the sky, the bright stars of the Pleiades can be seen without binoculars even from the heart of a light-polluted city. With a long exposure from a dark location, though, the dust cloud surrounding the Pleiades star cluster becomes very evident. The featured image was a long duration exposure taken last month from Namibia and covers a sky area m [...]
VLT Interferometer captures raging winds in famous massive stellar system.
An international team of astronomers have used the Very Large Telescope Interferometer to image the Eta Carinae star system in the greatest detail ever achieved. They found new and unexpected structures within the binary system, including in the area between the two stars where extremely high velocity stellar winds are colliding. These new insights into this enigmatic star system could lead to a better understanding of [...]
A U.S. cargo craft full of science gear and crew supplies is on its way to the International Space Station after a successful launch. Orbital ATK’s Cygnus resupply ship blasted off Monday night from Virginia on a mission to replenish the space station crew.
On the other side of the world in Kazakhstan, a Soyuz rocket is set to launch three Expedition 49-50 crew members to their new home in space early Wednesday morning. The new crew will arrive Friday morning and dock to the Poisk module af [...]
The next target for NASA's New Horizons mission -- which made a historic flight past Pluto in July 2015 -- apparently bears a colorful resemblance to its famous, main destination.
NASA's Hubble Space Telescope data suggests that 2014 MU69, a small Kuiper Belt object (KBO) about a billion miles (1.6 billion kilometers) beyond Pluto, is as red, if not redder, than Pluto. This is the first hint at the surface properties of the far-flung object that New Horizons will survey on Jan. 1, 2019.
