SUNSET: 
New Clues in Cooking up Planets and Stars
An early peak at a forming star system reveals tantalizing clues about its origin.
Telltale Shock Waves from Runaway Stars
Astronomers are now finding dozens of fast-moving runaway stars by searching for the bow shocks they create in interstellar gas and dust.
Astronomers Predict a Supernova
For the first time, astronomers have predicted the appearance of a supernova.
Newborn Star Puts on Star Wars Show
Infrared observations by the Hubble Space Telescope reveal jets from forming stars.
New Star and Exoplanet Names OK'd by IAU

Simulation Sees Supernova Innards
A new computer simulation provides a brief glimpse at what makes stellar bombs tick.
The Origin of Massive Stars
High-mass stars may outshine and outweigh the Sun, but observations show all stars may have had a similar beginning.
Astronomers Take Galaxy’s Pulse
Astronomers have caught a giant elliptical galaxy “shimmering” as its stars pulsate.

A new technique that relies on identifying stellar twins yields a novel way to measure the distances to stars.
Amateurs Help Discover Rare Eclipsing Binary
A collaboration of amateur and professional astronomers has uncovered a rare variety of eclipsing binary star - and a supernova in the making.
Brown Dwarfs Form Like Stars
Recent radio observations support the idea that brown dwarfs form like full-fledged stars do.
Fade Out (For Now) on SN 1987A
The famous supernova continues to transform: its necklace of hotspots is fading away as the shock wave moves further out.
