There are no large caverns inside Comet 67P/Churyumov-Gerasimenko. ESA's Rosetta mission has made measurements that clearly demonstrate this, solving a long-standing mystery. Comets are the icy remnants left over from the formation of the planets 4.6 billion years ago. A total of eight comets have now been visited by spacecraft and, thanks to these missions, we have built up a picture of the basic properties of these cosmic time capsules. While some questions have been answered, others have b...

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 be revised. The international team, led by Stephane Guilloteau ...

A newly upgraded camera that incorporates light sensors developed at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) is now one of the best cameras on the planet for studying outer space at red wavelengths that are too red for the human eye to see. Very distant astronomical objects appear much redder when observed on Earth due to an effect known as redshift, so this sensitivity to red light enables the camera to detect objects many billions of light years ...

The human body is made for living on Earth - take away the constant pull of gravity and muscles and bones begin to waste away. Living in space is hard on astronauts and ways must be found to keep them fit and safe. Bedrest study ESA and NASA are planning to confine human subjects to bed for 60 days in 2017 in Cologne, Germany to probe the effects of spaceflight, with periods in a centrifuge to test if artificial gravity can keep them healthy. Bedrest studies offer a way of testing measure...

Europe's ninth and tenth Galileo satellites have started broadcasting working navigation messages. These two satellites were launched together on 11 September last year. Once safely in orbit and their systems activated, their navigation payloads and search and rescue transponders were subjected to a rigorous process of in-orbit testing, to ensure their performance reached the necessary specifications to become part of the Galileo system. Radio-frequency measurements of the Galileo signa...
