The Webb Space Telescope will need to be extraordinarily cold in order to see the infrared light from the farthest reaches of the universe. Webb’s enormous sunshield will protect the telescope’s instruments from the Sun’s energy.

“Behind the Webb” is a recurring video series from HubbleSite, home of the Hubble Space Telescope and the upcoming Webb Space Telescope. Join host Mary Estacion as she goes behind the scenes to watch the construction and testing of the parts that will make Webb the world’s most powerful infrared telescope.

Webb’s Challenge: Keep It Cold

The making of the Webb Space Telescope’s mirrors is a complex process. Each surface must be precisely shaped to capture and direct the maximum amount of light to the telescope’s detectors. The mirrors must be ground and polished to a smooth curve that keeps light from bouncing off in unwanted directions. Join us at Tinsley Laboratories in Richmond, Calif., where engineers are bringing Webb’s mirrors to their exact requirements.

“Behind the Webb” is an ongoing series that follows the construction of the Webb Space Telescope, Hubble’s successor. Find more episodes at Hubblesite.org.

Backyard stargazers get a monthly guide to the northern hemisphere’s skywatching events with “Tonight’s Sky.” In March, the constellations of spring appear, heralding the change in seasons. Look for Gemini and Cancer as they dominate the night sky. “Tonight’s Sky” is produced by HubbleSite.org, online home of the Hubble Space Telescope. This is a recurring show, and you can find more episodes — and other astronomy videos — at HubbleSite.org.

Hubble images are made, not born. Images must be woven together from the incoming data from the cameras, cleaned up and given colors that bring out features that eyes would otherwise miss. In this video from HubbleSite.org, online home of the Hubble Space Telescope, a Hubble-imaged galaxy comes together on the screen at super-fast speed.

Learn more about how Hubble images are made by visiting Behind the Pictures.

Take a look at some of the most distant galaxies Hubble has ever seen, and find out why, when we look at the most distant objects in the universe, we are also seeing the cosmos’ earliest objects.

“Hubble’s Universe” is a recurring broadcast from HubbleSite, online home of the Hubble Space Telescope. Astrophysicist Frank Summers takes viewers on an in-depth tour of the latest Hubble discoveries. Find more episodes at HubbleSite.org.
