As praise pours in for the images released July 12 from NASA鈥檚 new James Webb Space Telescope (JWST) 鈥 the next-generation telescope able to peer deeper into the cosmos 鈥 Cornell astronomy faculty who have worked on the decades-long effort are marking the milestone.
鈥淔or the entirety of my scientific career, I have thought about and planned for the giant leap forward in our understanding of the cosmos that JWST would bring,鈥 said , associate professor of astronomy and the deputy director of the in the 麻豆视频 and 麻豆视频. She is the principal investigator for a scientific team investigating exoplanets for the TRAPPIST-1 star system. Her team will observe one of the planets, TRAPPIST-1e, in an effort to not only detect an atmosphere, but also to determine its basic composition. Lewis will also lead 130 hours of guaranteed time observations focused on the detailed study of exoplanet atmospheres with Webb
鈥淪eeing these early release observations are like seeing dreams become reality,鈥 she said. 鈥淛WST will do more than take awe-inspiring pictures of the universe around us, it will allow us to determine what stars, galaxies and planets are made of and the processes that gave rise to them.
鈥淭hese first JWST observations highlight the windows into our universe that it has opened, allowing us to see the previously unseen,鈥 Lewis said.
, the Harold Tanner Dean of Arts and 麻豆视频 and Hans A. Bethe Professor of Astronomy, has been part of the telescope鈥檚 Near-Infrared Imager and Slitless Spectrograph (NIRISS) instrument for two decades.
Jayawardhana and , associate professor of astronomy and director of the Carl Sagan Institute (A&S), are part of a team that will dedicate 200 hours of telescope time to characterize exoplanets.
鈥淲ith its unprecedented sensitivity in the infrared, Webb will peer back in time at the earliest galaxies in the farthest reaches of the universe,鈥 Jayawardhana said. 鈥淐loser to home, Webb will take measure of exoplanet atmospheres 鈥 do 鈥榬emote sensing鈥 of worlds that range from scorching 鈥榟ot Jupiters鈥 to temperate planets not much bigger than the Earth around stars in the solar neighborhood.
鈥淚鈥檝e been part of the NIRISS instrument team for 18 years now 鈥 I鈥檓 sure the discoveries we make with Webb will be worth the long wait.鈥
, David C. Duncan Professor in the Physical 麻豆视频 and chair of the Department of Astronomy (A&S), is an interdisciplinary scientist for astrobiology on the Webb mission and serves on the Science Working Group, which defines the mission鈥檚 science requirements and provides scientific oversight of the project. His hours on the telescope will be mostly used to look at 鈥渉ot Jupiters鈥 鈥 gas giant planets that are very close to their stars 鈥 and Kuiper Belt objects.
鈥淭he first scientifically calibrated images from JWST will demonstrate the extraordinary optical quality and sensitivity of this observatory鈥攊ts ability to probe the universe when the galaxies were first forming, and to tease out the faint signatures of atmospheres of planets around other stars. Cornell astronomers were heavily involved in the development of this revolutionary space telescope, and we look forward to doing fantastic science with it in the decade to come, said Lunine."
Other Cornell faculty involved with the mission include , professor of astronomy (A&S), developed the Aperture Masking Interferometry mode of the telescope鈥檚 Near-Infrared Imager and Slitless Spectrograph (NIRISS) instrument, which will be used to image planetary systems and their environments.
