Survivor of Stellar Collision is New Type of Pulsating Star

  A team of astronomers from the UK, Germany and Spain have observed the remnant of a stellar collision and discovered that its brightness varies in a way not seen before on this rare type of star. By analyzing the patterns in these brightness variations, astronomers will learn what really happens when stars collide.  Artist’s impression of [continue reading]

Bursts of Light Discovered in a Suspected Binary Protostar

  Two of NASA’s Great Observatories, the Spitzer and Hubble space telescopes, have teamed up to uncover a mysterious infant star that behaves like a police strobe light. This Hubble Space Telescope monochromatic-color image resolves the detailed structure around the protostar, consisting of two cavities that are traced by light scattered off their edges above [continue reading]

Hungry Twin Stars Gobbling Their First Meals

  Just-forming stars, like growing babies, are always hungry and must “feed” on huge amounts of gas and dust from dense envelopes surrounding them at birth. Now a team of astronomers including Robert Gutermuth, a University of Massachusetts Amherst expert in imaging data from the Spitzer Space Telescope, reports observing an unusual “baby” star that [continue reading]

Building Blocks of Life Found Around Young Sun-Like Star

  A team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) has spotted sugar molecules in the gas surrounding a young Sun-like star. This is the first time sugar been found in space around such a star, and the discovery shows that the building blocks of life are in the right place, at the [continue reading]

 Planetary Nebula is Born of Uncertain Parentage

A new Legacy Image from the Gemini Observatory reveals the remarkable complexity of the planetary nebula Sharpless 2-71 (Sh 2-71). Embroiled in a bit of controversy over its “birth parents” the nebula likely resulted from interactions between a pair of two old and dying stars. Legacy images like this one share the stunning beauty of [continue reading]

Ancient Egyptian Astronomers Observed A Variable Star

  The study of the ‘Demon star’, Algol, made by a research group of the University of Helsinki, Finland, has received both scientific and public attention. The period of the brightness variation of this eclipsing binary star has been connected to good prognoses three millennia ago. Papyrus Museum, Cairo, Egypt. The oldest Egyptian calendar.
