Webb finds ethanol, other icy ingredients for making planets

Baltimore MD (SPX) Mar 14, 2024
What do margaritas, vinegar, and ant stings have in common? They contain chemical ingredients that NASA's James Webb Space Telescope has identified surrounding two young protostars known as IRAS 2A and IRAS 23385. Although planets are not yet forming around those stars, these and other molecules detected there by Webb represent key ingredients for making potentially habitable worlds. An international team of astronomers used Webb's MIRI (Mid-Infrared Instrument) to identify a variety of icy compou ... read more

NASA's Hubble Finds Water Vapor in Small Exoplanet's Atmosphere

Montreal, Canada (SPX) Jan 26, 2024
Astronomers using NASA's Hubble Space Telescope observed the smallest exoplanet where water vapor has been detected in the atmosphere. At only approximately twice Earth's diameter, the planet GJ 9827d could be an example of potential planets with water-rich atmospheres elsewhere in our galaxy. "This would be the first time that we can directly show through an atmospheric detection, that these planets with water-rich atmospheres can actually exist around other stars," said team member Bjorn Benneke ... read more
