Latest Bipolar outflow Stories
An international team of astronomers has revealed a complicated outflow structure in the binary UY Aur (Aurigae).
Large stars can end their lives as violently cataclysmic supernovae. Small stars, in contrast, end up as planetary nebulae—colorful, glowing clouds of dust and gas. These nebulae were once thought to be mostly spherical.
Astronomers have discovered four pairs of stars that orbit each other in less than four hours using the United Kingdom Infrared Telescope in Hawaii.
The Hubble Space Telescope has unleashed a new image of a geyser of hot gas flowing from a newborn star.
NASA's Spitzer Space Telescope took this image of a baby star sprouting two identical jets (green lines emanating from fuzzy star).
Astronomers have combined two decades of Hubble observations to make unprecedented movies revealing never-before-seen details of the birth pangs of new stars.
Astronomers have discovered that two symmetrical jets shooting away from opposite sides of a blossoming star are experiencing a time delay: knots of gas and dust from one jet blast off four-and-a-half years later than identical knots from the other jet.
Astronomers have uncovered strong evidence that brown dwarfs form like stars.
University of Arizona astronomers who are probing the oxygen-rich environment around a supergiant star with one of the world's most sensitive radio telescopes have discovered a score of molecules that include compounds needed for life.
Jets of matter have been discovered around a very low mass 'failed star', mimicking a process seen in young stars. This suggests that these 'brown dwarfs' form in a similar manner to normal stars.
