Update, in march 7, 2002: and also the color of the cosmos Is ...Pale turquoise. Errrr, make the beige. Earlier this year, astronomers in ~ Johns Hopkins college made a splash at the American Astronomical society meeting as soon as they announced the the typical light indigenous the world is turquoise. Ivan Baldry and his collaborators amassed in-depth light measurements from much more than 200,000 galaxies. Castle then constructed a "cosmic spectrum," i beg your pardon represents all the power in the neighborhood universe emitted at various optical wavelength of light. They realized that if they just summed up those measurements, lock might be able to deduce something about the mean wavelength, or color, that the irradiate coming from their large sample the objects. For this reason they used their idea, and also they came up with a color that"s simply a few shades greener 보다 pale turquoise.Turns out, they to be wrong, and also the cosmos isn"t turquoise after ~ all. The astronomers in Baltimore to speak they discovered an error in the calculation. They had actually reached their initial conclusion making use of a item of complimentary software they had actually downloaded turn off the Web. Through that software, the average shade ended up showing up turquoise. Yet the astronomers didn"t realize the the program provided an unusual depiction for white. They"ve now recalculated the color using a more standard color of white. Therefore the universe now is, alas, a lot less interesting. Instead of having actually a turqouise cast, it"s in reality closer come boring old beige.hear to Richard Harris" march 7 report.

Stars in focus Astronomers say they"ve found a cluster of gas about a star development some 900 light years from earth that might be in the process of producing new planets. The discovery may administer a glimpse that the earliest step of planetary evolution. The evidence, report at the American Astronomical society meeting, reflects the promise ofnew an innovation for seeing into space. It used to be the astronomers might only view bright stars and galaxies v their telescopes. Dim planets outside Earth"s solar device were predicted, yet verifying their presence was beyond the reach of science. However recently, astronomers discovered they could detectthese elusive objects, and also so to be born a whole new field the astronomy: the examine of planets around other stars.The search for planets and other objects orbiting stars has been given an enormous boost by a new technology that helps telescopes get over the distortionthat"s caused by air swirling in the Earth"s atmosphere. A winter in the instrument constantly changes shape to compensate for the fun-house effect created by the wavy atmosphere. It"s dubbed adaptive optics, and it"s now in usage with several of the biggest telescopes in the world. hear to Richard Harris" Jan. 8 report for Morning Edition.

Universe a Precocious BabyNew findings indicate that the very first stars in the universe showed up in a sudden and also dramatic burst early in the background of the cosmos. Outcomes announced in ~ a NASA news conference Tuesday indicate that the cosmos was filled v stars 14 billion year ago, not lengthy after the "big bang" production of the universe. Astronomers make the efforts to understand the earliest years of the universe have actually been poring over pictures taken by the Hubble room Telescope in orbit about the Earth. These images show thousands of extremely faint galaxies far away and, therefore, far back in time. Astronomers spring at these extremely distant objects had actually thought that they were dim and placid and, consequently, no the website of violent to explode of star formation. Yet a an approach developed through Ken Lanzetta, native the State university of brand-new York in ~ Stony Brook, permitted him to figure out just how bright those objects in reality were by estimating their distance and also correcting for the vast journey the the light has actually made to get to us. Through this new technique, says Lanzetta, "We have discovered that the far-off early universe consists of far more light and, hence, far much more stars 보다 was formerly believed." Bruce Margon, of the room Telescope science Institute the operates Hubble, claims the findings suggest that the cosmos was a precocious baby, with star formation occurring an extremely shortly -- and violently -- ~ the big bang.
