Shining (Star)light on the Search for Life

08.02.2019
In the hunt for life on other worlds, astronomers scour over planets that are light-years away. They need ways to identify life from afar — but what counts as good evidence? To know a true sign when you see it, you must look beyond the planet itself, all the way to the gleaming star it orbits.

NASA’s Webb Telescope Shines with American Ingenuity

07.18.2019
Sending humans to the Moon is similar to building the worlds most complex and powerful space telescope, the James Webb Space Telescope. Both require surmounting countless hurdles, inventing new technologies while staring into the face of the unknown.

New Hubble Constant Measurement Adds to Mystery of Universe’s Expansion Rate

07.16.2019
Astronomers have made a new measurement of how fast the universe is expanding, using an entirely different kind of star than previous endeavors.

NASA Awards Contract for WFIRST Science Operations Center

07.01.2019
NASA has awarded a contract to the Association of Universities for Research in Astronomy (AURA) Space Telescope Science Institute (STScI) in Baltimore, Maryland for the agency’s Wide Field Infrared Survey Telescope (WFIRST) mission Science Operations Center (SOC).

Main Instrument for NASA’s WFIRST Mission Completes Milestone Review

06.26.2019
To know how the universe will end, we must know what has happened to it so far. This is just one mystery NASA's forthcoming Wide Field Infrared Survey Telescope (WFIRST) mission will tackle as it explores the distant cosmos. WFIRST's giant camera, the WFI, will be fundamental to this exploration, and it has just passed an important milestone.

NASA’s Webb Telescope Tech Improves Patients’ Vision

06.25.2019
The James Webb Space Telescope is scheduled to launch in 2021, but NASA technology developed for this upcoming innovative observatory is already hard at work here on Earth, helping improve LASIK eye surgery.

NASA’s Webb Telescope Will Survey Saturn and its Moon Titan

06.19.2019

NASA's Webb Sunshield Undergoes Rocket Fitting, More Testing

06.12.2019
NASA's James Webb Space Telescope’s spacecraft element, which consists of the observatory’s spacecraft bus and the sunshield, was put in the same folded-up configuration that it will be in when mounted on atop a rocket for launch in 2021.

How the Webb Telescope Will Explore Mars

06.04.2019
When NASA's James Webb Space Telescope, launching in 2021, reaches its destination a million miles from Earth, it will be able to see the whole disk of Mars every two years. If a global dust storm envelops the Red Planet at a time when Webb could see it, the powerful space telescope could gather information about the storm.

NASA’s James Webb Space Telescope Emerges Successfully from Final Thermal Vacuum Test

05.30.2019
NASA’s James Webb Space Telescope has successfully cleared another critical testing milestone, taking this ambitious observatory one step closer to its 2021 launch.
