Behind the Webb: All Sewn Up (Episode 21)

Posted by

The James Webb Space Telescope’s tennis court-sized sunshield is made of a special material called Kapton. But finding Kapton this size is impossible, so engineers must assemble pieces in order to make the sunshield the proper size. This episode of Behind the Webb shows us how the sunshield becomes the proper size and how it’s being tested to ensure it will withstand the rigors of space. (Please note: Some parts of the video are obscured due to the proprietary processes used to make the sunshield.)

“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.

Xbox One Grill – Frying An Egg

Posted by

In this experiment, I heated up the top part of my Xbox One and quickly placed an egg to see if anything would occur. Behold, the egg started sizzling and almost fully turned white before enjoying it on a plate.

Tonight’s Sky: December 2013

Posted by

Backyard stargazers get a monthly guide to the northern hemisphere’s skywatching events with “Tonight’s Sky.” In December, look for the double-star Eta Cassiopeiae with binoculars, and brave the cold to see the Geminid meteor shower in mid-month.

“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.

Great Comets from Humble Origins & Eyes on ISON

Great Comets from Humble Origins & Eyes on ISON
Dr. Frank Summers, Space Telescope Science Institute

Comets can be one of the most amazing sights in the heavens, with bright, naked-eye comas and tails stretching across half the sky. The most spectacular comet appearances are called “great” comets, but such an occurrence is infrequent enough that it is also nicknamed a “comet of the century.” In preparation for the Thanksgiving Day perihelion passage of Comet ISON, along with its great possibilities, it’s a proper time to examine the humble origins, from the most rural parts of the solar system, of these briefly blazing celestial visitors.
