'''Be''' Beryllium is a relatively rare element in both the Earth and the universe. The element is not known to be necessary or useful for either plant or animal life. It is extremely toxic, thats why its practical use is somewhat limited. It has one of the highest meltinhg points of all the light metaksm and it has exceptional flexural rigidity. It has the abilty to reduce water when its oxide film is removed, that means it is very hard to produce this metal in its pure form. [http://en.wikipedia.org/wiki/Beryllium Beryllium wiki] | '''Be''' The name beryllium comes (via Latin: Beryllus and French: Béryl) from the Greek βήρυλλος, bērullos, beryl, from Prakrit veruliya (वॆरुलिय), from Pāli veḷuriya (वेलुरिय); veḷiru (भेलिरु) or, viḷar (भिलर्), "to become pale," in reference to the pale semiprecious gemstone beryl. | ||

Anyways the large haydron colliders accelorator ALICE uses Be uses a beryllium beam-pipe. Because if Be's low atomic numer, it is almost transparent to energetic particles. Therefore one uses Be in the beam pipe arround the collision region in collider particle physics. | Anyways the large haydron colliders accelorator ALICE uses Be uses a beryllium beam-pipe.

'''The succesor of the Hubble Telescope!''' | |||
The James Webb Space Telescope will have 18 hexagonal beryllium sections for its mirrors. Because JWST will face a temperature of −240 degrees Celsius (33 kelvins), the mirror is made of beryllium, capable of handling extreme cold better than glass. Beryllium contracts and deforms less than glass - and remains more uniform - in such temperatures. For the same reason, the optics of the Spitzer Space Telescope are entirely built of beryllium metal. | The James Webb Space Telescope will have 18 hexagonal beryllium sections for its mirrors.

The James Webb Space Telescope (JWST) is a large, infrared-optimized space telescope, scheduled for launch in 2014. JWST will find the first galaxies that formed in the early Universe, connecting the Big Bang to our own Milky Way Galaxy. JWST will peer through dusty clouds to see stars forming planetary systems, connecting the Milky Way to our own Solar System. JWST's instruments will be designed to work primarily in the infrared range of the electromagnetic spectrum, with some capability in the visible range. | |||
This could be an interesting perspective into the process of Telescope building, and kind of showcasing a new piece of NASA Tech. | |||
