Hyperfast Star Proven To Be Alien

Jordan — Tue, 29 Jan 2008 21:59:16 +0000

A young star is speeding away from the Milky Way so fast that astronomers have been puzzled by where it came from; based on its young age it has traveled too far to have come from our galaxy.

Hydrogen beast is closing in on the Milky Way

Jordan — Tue, 15 Jan 2008 04:42:11 +0000

It’s large, it’s fast, and it’s heading toward the Milky Way. Less than 40 million years from now, a giant cloud of hydrogen gas, clocked at 250 kilometers per second, will smash into our home galaxy, likely setting off a huge burst of star formation.

Earth Barely Big Enough for Life, Study Says

Jordan — Tue, 15 Jan 2008 04:42:07 +0000

Astronomers searching for habitable worlds might do best to look for rocky planets several times larger than Earth. That’s because, according to a new study, our planet is at the lower end of the size range needed for plate tectonics—which scientists believe are vital for stabilizing temperatures enough for life.

Two Supermassive Black Holes Discovered in Same Galaxy

Jordan — Sat, 03 Nov 2007 22:51:14 +0000

For the first time, scientists have proof two supermassive black holes exist together in the same galaxy, thanks to data from NASA’s Chandra X-ray Observatory. These black holes are orbiting each other and will merge several hundred million years from now, to create an even larger black hole resulting in a catastrophic event that will unleash intense radiation and gravitational waves.

VY Canis Majoris is a red hyper-giant. This is the largest known star. If it were possible for a human to walk on the surface of Canis Majoris, at 3 miles an hour for 8 hours a day, it would take him or her 162,000 years to walk the entire circumference (compared with 2 years 11 months to complete the same task on the Earth).

Early humans successfully fended off a virus that infected chimpanzees by evolving a protein capable of neutralizing it, according to a new study. But what goes around comes around, evolutionarily speaking: Four million years later, the same protein seems to have left us more vulnerable than other primates to the human immunodeficiency virus (HIV).
