IBEX Captures ‘Alien’ Material From Beyond Our Solar System

If we could board the starship Enterprise-D and were able to look through Giordi LaForge’s visor we might be able to see the interstellar medium – the ‘stuff’ between the stars — as wispy clouds of oxygen, hydrogen, helium and neon. Instead, since we are back in the 21st century, we have the Interstellar Boundary […]

Gamma Ray Bursts (GRBs) are among the most energetic phenomena astronomers regularly observe. These events are triggered by massive explosions and a large amount of the energy if focused into narrow beams that sweep across the universe. These beams are so tightly concentrated that they can be seen across the visible universe and allow astronomers […]

Local Interstellar Gas Mapped in 3-D

by Nancy Atkinson February 9, 2010

Astronomers have created a new 3D map of the interstellar gas in the local area around our Sun. “Local” is a relative term, as the map extends to an area of 300 parsecs and provides new absorption measurements towards more than 1800 stars. The group of astronomers, from the US and France, were able to […]
