Scientists will use NASA’s James Webb Space Telescope to study sections of the sky previously observed by NASA’s Great Observatories, including the Hubble Space Telescope and the Spitzer Space Telescope, to understand the creation of the universe’s first galaxies and stars. After it launches and is fully commissioned, scientists plan to focus Webb telescope on sections of the Hubble Ultra-Deep Field (HUDF) and the Great Observatories Origins Deep Survey (GOODS)...

NASA’s Webb Telescope will study Our Solar system’s ‘Ocean Worlds’

Possible spectroscopy results from one of Europa’s water plumes.

NASA’s James Webb Space Telescope will use its capabilities to study the “ocean worlds” of Jupiter’s moon Europa and Saturn’s moon Enceladus, adding to observations previously made by NASA’s Galileo and Cassini orbiters. The Webb telescope’s observations could also help guide future missions to the icy moons.

Europa and Enceladus are on the Webb telescope’s list of targets chosen by guaranteed time observers, scientists who helped develop the telescope and thus get to be among the first to use it to observe the...

Nearby Star is a good Model of our Early Solar System

This is an artist's illustration of the epsilon Eridani system showing Epsilon Eridani b, right foreground, a Jupiter-mass planet orbiting its parent star at the outside edge of an asteroid belt. In the background can be seen another narrow asteroid or comet belt plus an outermost belt similar in size to our solar system's Kuiper Belt. The similarity of the structure of the Epsilon Eridani system to our solar system is remarkable, although Epsilon Eridani is much younger than our sun. SOFIA observations confirmed the existence of the asteroid belt adjacent to the orbit of the Jovian planet. Credit: Illustration by NASA/SOFIA/Lynette Cook

With the discovery of seven earth-sized planets around the TRAPPIST-1 star 40 light years away, astronomers are looking to the upcoming James Webb Space Telescope to help us find out if any of these planets could possibly support life. “If these planets have atmospheres, the James Webb Space Telescope will be the key to unlocking their secrets,” said Doug Hudgins, Exoplanet Program Scientist at NASA Headquarters in Washington. “In the meantime, NASA’s missions like Spitzer, Hubble, and Kepler are following up on these planets.”

“These are the best Earth-sized planets for the James Webb Space Telescope to characteriz...
