  • This outer shell of material eventually cools and disperses to form a variety of different shapes, including wispy clouds, expanding bubbles or ring-shaped nebulas like M57. (space.com)
  • This dramatic new image of cosmic clouds in the constellation of Orion reveals what seems to be a fiery ribbon in the sky. (eso.org)
  • The evolution of dust traces out paths in which the Universe recycles material, in processes analogous to the daily recycling steps with which many people are familiar: production, storage, processing, collection, consumption, and discarding. (wikipedia.org)
  • If these supernova blasts are repeated, they can have the effect of clearing gas and dust in the vicinity and creating those superbubble voids like the one spotted by the team. (yahoo.com)

  • We're thrilled Cassini could make this detection, given that our instrument was designed primarily to measure dust from within the Saturn system, as well as all the other demands on the spacecraft," said Marcia Burton, a Cassini fields and particles scientist at NASA's Jet Propulsion Laboratory in Pasadena, California, and a co-author of the paper.
