This observation of a gas giant planet orbiting a Sun-like star 700 light-years away provides important insights into the composition and formation of the planet.

To further this exploration, NASA is supporting the early-stage study of a concept for a hybrid observatory that would combine a ground-based telescope with a space-based starshade.

Another intriguing possibility, however, is that 55 Cancri e is not tidally locked. Instead, it may be like Mercury, rotating three times for every two orbits (what’s known as a 3:2 resonance). As a result, the planet would...

There are still more challenges that the team will have to face before MIRI can start its scientific mission. Now that the instrument is at operating temperature, team members will take test images of stars and other known...

Now that Webb’s primary mirror segments and secondary mirror have been deployed from their launch positions, engineers will begin the sophisticated three-month process of aligning the telescope’s optics to nearly nanometer...

NASA’s James Webb Space Telescope team fully deployed its 21-foot, gold-coated primary mirror, successfully completing the final stage of all major spacecraft deployments to prepare for science operations.

On Jan. 4, 2022, engineers successfully completed the deployment of the James Webb Space Telescope’s sunshield, seen here during its final deployment test on Earth in December 2020 at Northrop Grumman in Redondo Beach,...

The Webb mission will explore every phase of cosmic history – from within the solar system to the most distant observable galaxies in the early universe, and everything in between...

From NASA Editor’s note: This release was updated on Dec. 25 to reflect the observatory’s release at approximately 870 miles (1,400 kilometers). NASA’s James Webb Space Telescope launched at 7:20 a.m.…

Webb is targeted to launch at 7:20 a.m. EST Saturday, Dec. 25, on an ESA-provided Ariane 5 rocket from Europe’s Spaceport in Kourou, French Guiana, on the northeastern coast of South America.

When NASA's James Webb Space Telescope begins science operations in 2022, one of its first tasks will be an ambitious program to map the earliest structures in the universe...

In a nearby stellar nursery called the Orion Nebula, young, massive stars are blasting far-ultraviolet light at the cloud of dust and gas from which they were born...

What, precisely, is happening at its core to cause all this activity? Upcoming observations led by Nora Lützgendorf and Macarena García Marín of the European Space Agency using NASA's James Webb Space Telescope will allow...

Today researchers at Harvard-Smithsonian made an exciting announcement: a newly discovered planet may be the best candidate yet for finding life outside of our solar system...
