“James Webb Space Telescope's Golden Mirror” was uploaded to Flickr

Inside the clean room at NASA's Goddard Space Flight Center, the golden James Webb Space Telescope is viewed from overhead with its secondary mirror booms stowed. In the next few months, engineers will install other key elements, and take additional measurements to ensure the telescope is ready for space. via NASA ift.tt/1O0fSJy

“Light Echoes Used to Study Protoplanetary Disks” was uploaded to Flickr

This illustration shows a star surrounded by a protoplanetary disk. A new study uses data from NASA's Spitzer Space Telescope and four ground-based telescopes to determine the distance from a star to the inner rim of its surrounding protoplanetary disk. Researchers used a method called "photo-reverberation," also known as "light echoes. via NASA ift.tt/26rHbbb
