The International Space Station Expedition 42 crew were hard at work last week on a variety of robotics and research tasks, along with preparation for a rescheduled cargo delivery and future spacewalks. Work on scientific studies about fruit fly immune systems, microbial growth, and cyclone […]

Rosetta Team Focusing on Upcoming Comet and Lander Science, Planning Ultra Close Flyby

From the location where it came to rest after bounces, the Philae lander of the European Space Agency’s Rosetta mission captured this view of a cliff on the nucleus of comet 67P/Churyumov-Gerasimenko. The feature is called “Perihelion Cliff.” The image is from the lander’s CIVA camera. Credit: ESA/Rosetta/Philae/CIVA

The team guiding Europe’s history-making Rosetta […]

Of Warm Gas and Galaxy Mergers: Collisions Between Galaxies Can Halt Star Formation, According to New Study

A composite image of the gravitationally interacting galaxies NGC 3226 (at the top) and NGC 3227 (bottom), which clearly shows the tidally generated large structures that surround them as a result of a past collision with a third galaxy. Optical wavelengths in the image are shown in gray scale. The infrared glow of dust […]
