Webb Space Telescope Detects Universe’s Most Distant Complex Organic Molecules

Astronomers using the Webb telescope discovered evidence of complex organic molecules in a galaxy more than 12 billion light-years away. The galaxy lines up almost perfectly with a second galaxy only 3 billion light-years away from our perspective on Earth. In this false-color Webb image, the foreground galaxy is shown in blue, while the background galaxy is red. The organic molecules are highlighted in orange.

An international research team led by UCLA astrophysicists has confirmed the existence of the faintest galaxy ever seen in the early universe. The galaxy, called JD1, is one of the most distant identified to date, and it is typical of the kinds of galaxies that burned through the fog of hydrogen atoms left over from the Big Bang, letting light shine through the universe and shaping it into what exists today.

The discovery was made using NASA’s James Webb Space Telescope, and the findings are published in the journal Nature.

The first billion years of the universe’s life were a crucial period in its evolution. After the Big Bang, approximately 13...

NIRISS instrument on Webb Maps an Ultra-hot Jupiter-like Exoplanet’s Atmosphere

NIRISS instrument on Webb maps an ultra-hot Jupiter's atmosphere
The team obtained the thermal emission spectrum of WASP-18 b by measuring the amount of light it emits over the Webb Telescope’s NIRISS SOSS 0.85 – 2.8 micron wavelength range, capturing 65% of the total energy emitted by the planet. WASP-18 b is so hot on the day side of this tidally locked planet that water molecules would be vaporized. Webb directly observed water vapor on the planet in even relatively small amounts, indicating the sensitivity of the observatory. Credit: NASA/JPL-Caltech (R. Hurt/IPAC)

400 light-years out there is something that is so tantalizing that astronomers have been studying it since its discovery in 2009. One orbit for WASP-18 b around its star that is slightly larger than our sun takes just 23 hours. There is nothing like it in our solar system.

Webb Telescope finds Towering Plume of Water escaping from one of Saturn’s Moons

Courtesy of NASA/ESA/CSA/Alyssa Pagan (STScI)/Geronimo Villanueva (NASA-GSFC) SwRI contributed to new Cycle 1 JWST findings that show the plume of water escaping from Saturn’s moon Enceladus extends 6,000 miles or more than 40 times the moon’s size. In light of this discovery, SwRI’s Dr. Christopher Glein was awarded a NASA JWST Cycle 2 allocation to study the plume as well as the icy surface of Enceladus, to better understand the potential habitability of this ocean world.

Two Southwest Research Institute scientists were part of a James Webb Space Telescope (JWST) team that observed a towering plume of water vapor more than 6,000 miles long—roughly the distance from the U.S. to Japan—spewing from the surface of Saturn’s moon, Enceladus...
