Astronomy & Astrophysics is publishing new 3D maps of the interstellar gas in the local area around our Sun. A French-American team of astronomers presents new absorption measurements towards more than 1800 stars. They were able to characterize the properties of the interstellar gas within each sight line. This week, Astronomy & Astrophysics publishes new 3D maps of the interstellar gas situated in an area 300 parsecs around the Sun. A French-American team of astronomers presents new...

GREENBELT, Md., Aug. 28 /PRNewswire-USNewswire/ -- The dust-filled disks where new planets may be forming around other stars occasionally take on some difficult-to-understand shapes. Now, a team led by John Debes at NASA's Goddard Space Flight Center in Greenbelt, Md., finds that a star's motion through interstellar gas can account for many of them.

The dust-filled disks where new planets may be forming around other stars occasionally take on some difficult-to-understand shapes. Now, a team led by John Debes at NASA's Goddard Space Flight Center in Greenbelt, Md., finds that a star's motion through interstellar gas can account for many of them. "The disks contain small comet- or asteroid-like bodies that may grow to form planets," Debes said. "These small bodies often collide, which produces a lot of fine dust." As the star moves through...

Astronomers based at Jodrell Bank Observatory have found evidence that giant whirlpools form in the wake of stars as they move through clouds in interstellar space.  The discovery will be presented by Dr Chris Wareing at the Royal Astronomical Society's National Astronomy Meeting in Preston on 17th April. Dr Wareing and his colleagues used the COBRA supercomputer to simulate in three-dimensions the movement of a dying star through surrounding interstellar gas. At the end of their life,...
