Intriguing 'Life' Signal on Venus Was Plain Old Sulphur Dioxide, New Research Suggests
Scientists stunned the world last year by claiming to have discovered traces of phosphine in the Venusian clouds. New research suggests this gas — which, excitingly, is produced by microbes — was not actually responsible for the signal they detected. Instead, it was likely sulfur dioxide, a not-so-thrilling chemical. Victoria Meadows, professor of astronomy at the UW, is quoted. Andrew Lincowski, a doctoral student in astronomy and astrobiology at the UW, is mentioned.

The Hubble telescope has revealed a 'very dramatic and very weird' fading nebula in deep space
NASA reported last week that the Stingray Nebula, which is 18,000 light-years from Earth and located near the southern constellation Ara, has dimmed remarkably fast, fading over just 20 years. Bruce Balick, professor emeritus of astronomy at the UW, is quoted.

NASA Spots 'Very Dramatic and Very Weird" Fading of Already Unusual Planetary Nebula
The Stingray Nebula, a shroud of gas around an aging star, was already unusual: It is by far the youngest such object in space. But scientists say that it is now getting dimmer as rapidly as it appeared. Its brightness has dropped by a factor of nearly 1,000 over 20 years, and the bright tendrils that once wrapped around its edges are gone. Bruce Balick, professor emeritus of astronomy at the UW, is quoted.
