Remarkable White Dwarf Star Possibly Coldest, Dimmest Ever Detected

June 23, 2014
A team of astronomers has identified possibly the coldest, faintest white dwarf star ever detected. This ancient stellar remnant is so cool that its carbon has crystallized, forming — in effect — an Earth-size diamond in space… Read More

Orion Rocks! Pebble-Size Particles May Jump-Start Planet Formation

August 27, 2014
Rocky planets like Earth start out as microscopic bits of dust tinier than a grain of sand, or so theories predict. Astronomers using the National Science Foundation’s (NSF) Green Bank Telescope (GBT) have discovered that filaments of star-forming gas near the Orion Nebula may be brimming with pebble-size particles — planetary building blocks 100 to 1,000 times larger than the dust grains typically found around protostars… Read More
