NASA’s James Webb Space Telescope is now experiencing all seasons from hot to cold as it undergoes the thermal stability test. It’s also a powerful statement about the amazing capabilities of Webb that we’ve never had before.” “It’s amazing that we can identify molecules billions of light-years away that we’re familiar with here on Earth, even if they show up in ways we don’t like, like smog and smoke. ![]() “Discoveries like this are precisely what Webb was built to do: understand the earliest stages of the universe in new and exciting ways,” says co-author and University of Illinois Urbana-Champaign graduate student Kedar Phadke. This small satellite galaxy of the Milky Way provided a dense star field to test Webb’s performance. At 12 billion light years from Earth, the galaxy is a snapshot from just 1.5 billion years after the Big Bang – a little over 10 percent the current age of the universe. The galaxy where the sooty organic molecules were found was first discovered in 2013 by the National Science Foundation’s South Pole Telescope. NASA’s James Webb Space Telescope captured this image of the dusty debris disk surrounding the young star Fomalhaut using its Mid-Infrared Instrument.
