Dear Dr=20 Peiser,

Kardashev's scheme for classifying civilisations (even as = refined=20 by Carl

of human history.  (Ref: CCNet 156/2004 - 29 November = 2004:=20 TOWARDS A

A threshold in brain power is crossed, which leads to=20 --

They estimate it = resides about 12 light-years away - only three times farther than Alpha = Centauri. Niall Deacon, Nigel Hambly, and John Cooke of the University of = Edinburgh were comparing infrared surveys of the sky from different = years when they noticed a star moving east-southeast at 1.13" per year. Such a large proper motion signaled the star might lie nearby. In = the same way, when you ride down the highway, nearby objects such as = road signs appear to whiz by, whereas distant mountains appear almost = stationary. In order to get a reliable distance, though, astronomers = must measure parallax - the tiny shift that results in a star's apparent = position as the Earth orbits the Sun. The larger the parallax, the = closer the star is.=20 =20 Unfortunately, the photographic plates the astronomers used are = too crude to reveal any but the largest parallaxes. "I actually made a = mistake in my calculations and thought it was far more distant than it = is," says Deacon. So, initially, he didn't try to measure the parallax - = he thought it would be too small to detect. But then he took another look at the data. As he and his = colleagues will report in an upcoming issue of the journal Astronomy and = Astrophysics, he found a parallax that places the star 11.8 +/- 1.8 = light-years from the Sun. If the star's distance is exactly 11.8 = light-years, it ranks as the 17th nearest star system to the Sun, a tad = closer than such well-known neighbors as Epsilon (?) Indi and Tau (?) = Ceti. However, nearby-star expert Todd Henry at Georgia State University = thinks the newfound star will prove to be slightly farther because it's = so faint. "I'm hoping it's within 5 parsecs [16.3 light-years], because = the news here is that this would be the fourth new object found within 5 = parsecs since 2000." Henry and his colleagues plan to measure a precise = parallax and distance, but that will take a year. Right now, little is known about the new star. Its name is SIPS = 1259-4336 (SIPS stands for "Southern Infrared Proper Motion Survey"; the = numbers give its right ascension and declination). The star is a red = dwarf with a spectral type of M8, implying a mass only about one-tenth = of the Sun's. Despite their dimness, red dwarfs account for 80 percent = of all stars in the galaxy. In contrast, bright yellow stars like the = Sun make up only 4 percent. No one has yet measured the star's Doppler shift, so its velocity = through space and its orbit around the galaxy are unknown. Nor do = astronomers know its abundance of heavy elements like iron and titanium; = such information helps astronomers assess a star's age. Because the star was discovered at infrared wavelengths, where red = dwarfs emit most of their energy, the star's brightness at visual = wavelengths has not yet been measured. Deacon estimates that it's 19th = magnitude, and Henry's group plans to measure it in a few weeks. If the Sun emitted as little light as this star, noon would be = darker than a moonlit night.=20 =20 =20 =20 Ken Croswell is an astronomer living in Berkeley, California, and = author of Magnificent Mars (Free Press, 2003) and Magnificent Universe = (Simon & Schuster, 1999).
