Two cosmonauts are cleaning up today after a successful spacewalk on Wednesday. The other crew members are working on life support gear and taking out the trash.
Flight Engineers Yuri Malenchenko and Sergey Volkov completed the third spacewalk of Expedition 46 after installing hardware and science gear and conducting experiments. Today the duo are cleaning and recharging their Orlan spacesuits and stowing their tools.
British astronaut Tim Peake helped Malenchenko and Volkov as he stowed t [...]
The 18th and final primary mirror segment is installed on what will be the biggest and most powerful space telescope ever launched. The final mirror installation Wednesday at NASA’s Goddard Space Flight Center in Greenbelt, Maryland marks an important milestone in the assembly of the agency’s James Webb Space Telescope.
“Scientists and engineers have been working tirelessly to install these incredible, nearly perfect mirrors that will focus light from previously hidden realms of planeta [...]
An international team led by a researcher from Hiroshima University has succeeded in revealing the detailed structure of a massive ionized gas outflow streaming from the starburst galaxy NGC 6240 (Figure 1). The team used the Suprime-Cam mounted on the 8.2-meter Subaru Telescope on Maunakea in Hawaii.
The ionized gas the astronomers observed extends across 300,000 light-years and is carried out of the galaxy by a powerful superwind. That wind is driven by intense star-forming activity at the [...]
Dwarf planet Ceres is the largest object in the Solar System's main asteroid belt, with a diameter of about 950 kilometers (590 miles). Ceres is seen here in approximately true color, based on image data from the Dawn spacecraft recorded on May 4, 2015. On that date, Dawn's orbit stood 13,642 kilometers above the surface of the small world.
Two of Ceres' famous mysterious bright spots at Oxo crater and Haulani crater are near center and center right of this view. Casting a telltale shadow at [...]
Expedition 46 Flight Engineers Yuri Malenchenko and Sergey Volkov of Roscosmos successfully concluded their spacewalk at 12:40 p.m. EST.
The cosmonauts installed and retrieved a number of science experiments and conducted extensive photography of the external surfaces of the Russian segment of the International Space Station.
The 4 hour and 45 minute spacewalk was the sixth for Malenchenko and the fourth for Volkov. Space station crew members have conducted 193 spacewalks in support of [...]
ALMA finds unexpectedly cold grains in planet-forming disc.
Astronomers have used the ALMA and IRAM telescopes to make the first direct measurement of the temperature of the large dust grains in the outer parts of a planet-forming disc around a young star. By applying a novel technique to observations of an object nicknamed the Flying Saucer they find that the grains are much colder than expected: −266 degrees Celsius. This surprising result suggests that models of these discs may need to b [...]
NASA's solar-powered Juno spacecraft successfully executed a maneuver to adjust its flight path today, Feb. 3. The maneuver refined the spacecraft's trajectory, helping set the stage for Juno's arrival at the solar system's largest planetary inhabitant five months and a day from now.
"This is the first of two trajectory adjustments that fine tune Juno's orbit around the sun, perfecting our rendezvous with Jupiter on July 4th at 8:18 p.m. PDT [11:18 p.m. EDT]," said Scott Bolton, Juno principa [...]
