Astronomers Get Rare Glimpse of the 'Nasty' Lifestyles of Massive Stars

Artist’s illustration of the vast disk of gas surrounding the massive and bright Wolf-Rayet star NaSt1, affectionately nicknamed ‘Nasty 1’. Observations with the Hubble and Chandra space telescopes revealed that contrary to other Wolf-Rayet stars, NaSt1 is feeding material into its companion star (shown here by the bridge of bright material connecting the two […]

Dust in the (Interstellar) Wind: Seven Particles of Possible Interstellar Origin Identified in Samples Returned by NASA's Stardust Spacecraft

A team of researchers has identified seven dust particles that were returned to Earth in 2006 by NASA’s Stardust spacecraft, which might have originated in the interstellar medium. This false-color image shows a diffraction pattern created by one of these particles, named Orion. Image Credit: Zack Gainsforth

Following a preliminary analysis of the dust […]
