Using the Hubble Space Telescope (HST), astronomers from Villanova University have analyzed spectroscopic observations of a nearby old nova known as T Aurigae. Results of this study, published March 29 on the arXiv pre-print ...
In the early solar system, a "protoplanetary disk" of dust and gas rotated around the sun and eventually coalesced into the planets we know today.

Planetary systems form out of the remnant gas and dust of a primordial star. The material collapses into a protoplanetary disk around the young star, and the clumps that form within the disk eventually become planets, asteroids, ...
