For the last time while it is on Earth, the world’s largest and most powerful space science telescope opened its iconic primary mirror. This event marked a key milestone in preparing the observatory for launch later this year. As part of NASA’s James Webb Space Telescope’s final tests, the 6.5 meter (21 […]

Both sides of the James Webb Space Telescope’s sunshield were lifted vertically in preparation for the folding of the sunshield layers.

Evidence indicates that large amounts of cosmic dust are produced as the stellar winds of massive stars collide in Wolf-Rayet binary or multiple-star systems. As the stars orbit each other and dust is produced, a distinctive pinwheel pattern is formed, as shown in this image from the European Southern Observatory. […]

An artist impression of the James Webb Space Telescope, fully deployed.

The papers are published in The Astrophysical Journal and the Monthly Notices […]

This artist’s illustration portrays two galaxies that existed in the first billion years of the universe. The larger galaxy at left hosts a brilliant quasar at its center, whose glow is powered by hot matter surrounding a supermassive black hole. Scientists calculate that the resolution and infrared sensitivity of NASA’s […]

For the first time ever, testing teams at Northrop Grumman in Redondo Beach, California carefully lifted the fully assembled James Webb Space Telescope in order to prepare it for transport to nearby acoustic and sine-vibration testing facilities.
