Using JWST, scientists observe silicate clouds and measure the temperature of exoplanets
With help from the joint NASA/ESA/CSA James Webb Space Telescope, two teams of scientists have made groundbreaking, first-of-their-kind discoveries on two exoplanets. One team utilized the immense power of Webb’s Mid-Infrared Instrument (MIRI) and Near-Infrared Spectrograph (NIRSpec) instruments to observe and characterize clouds and molecules in the atmosphere of an exoplanet located 40 light-years away.…

Webb peers at young star’s dusty disk, discovers an exoplanet, and uncovers star formation
At the 241st meeting of the American Astronomical Society (AAS) on Jan. 11, three teams presented research that utilized the capabilities of NASA’s James Webb Space Telescope. The first team used Webb to observe the dusty disk surrounding a young red dwarf star, the second to discover an exoplanet, and the third used the telescope’s…

As Webb begins observing exoplanets, scientists use Spitzer data & brown dwarfs to reveal how silicate clouds form
In a new study from a group of researchers in Canada, data from NASA’s now-retired Spitzer Space Telescope was used to determine the conditions under which silicate clouds form on distant exoplanets outside of our solar system — giving scientists insight into what’s inside the atmospheres of exoplanets similar in size, temperature, and composition to…

NASA, ESA, CSA release historic first images from the James Webb Space Telescope
NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA) have released the first set of full-color images taken by the James Webb Space Telescope — the world’s newest, most powerful, and largest space telescope. A total of five images were released, with the first image being unveiled by United States President Joe…

Seeing the universe in the Mid-Infrared with James Webb’s MIRI instrument
The James Webb Space Telescope (JWST), presently tracking toward a launch no earlier than December 22 on an Ariane 5 rocket from the Guiana Space Centre in South America, will revolutionize in-space astronomy, particularly with its Mid-InfraRed Instrument, or MIRI. The instrument itself requires special cooling to drop its temperature to just 6 Kelvin —…
