In this third episode of the Science@ESA vodcast series we investigate the infrared Universe, explore discoveries made by ground-breaking infrared space telescopes, and take a look at Herschel - ESA's pioneering infrared space telescope.

Herschel, ESA's cutting-edge space observatory, will carry the largest, most powerful infrared telescope ever flown in space. A pioneering mission to study the origin and evolution of stars and galaxies, it will help understand how the Universe came to be what it is today.

The first observatory to cover the entire range from far-infrared to sub-millimetre wavelengths and bridge the two, Herschel will explore further in the far-infrared than any previous mission, studying otherwise invisible dusty and cold regions of the cosmos, both near and far.

Herschel will tap into unexploited wavelengths, seeing phenomena out of reach for other observatories, at a level of detail that has not been captured before. The telescope's primary mirror is 3.5 m in diameter, more than four times larger than any previous infrared space telescope and almost one and a half times larger than that of the Hubble Space Telescope. The telescope will collect almost twenty times more light than any previous infrared space telescope.

The cutting-edge spacecraft carries three advanced science instruments: two cameras and a very high resolution spectrometer; their detectors are cooled to temperatures close to absolute zero by a sophisticated cryogenic system.

Lets cancel the bailouts of all these dumb financial parasites and spend it all on scence missions.

It seems you have the wrong channel theeyeisblind. The catty 13 yr. old girl channel is elsewhere. This channel is for those interested in science. Run along now.

Shes not hot at all but this is intresting

[bioLightbulb]

My thoughts while watching this video: Pink Floyd Pink Floyd Pink Floyd Pink Floyd Accent Pink Floyd new person talking back to accent.

If I were a science writer, I would never write for shows featuring female presenters. Because no matter how good the writing, how good the effects, or how fascinating the material presented, 20% of the male audience never makes it past their first view of the presenter's tits.

Geez, guys. Just watch the video and try to learn something for a change. She would never do you, anyway.

Free energy is finaly here!But the powerfull Oil business won't alow common ppl to know this,Find the real deal, a free energy device at LT-MAGNET-MOTORdotCOM ,Start the energy revolution!

[hungarylnnjsd]

True Free energy devices exist,But the Establishment doesn't want ppl to know this,Find a motor that needs no fuel or input at LT-MAGNET-MOTORdotCOM ,Let the revolution begin!

[MaximvsDread]

Who else wants to choke her out?

[boogiebuddy01]

maybe dark matter is so cold and thats why it cant be detected by our telescopes

[KenjiSmashMassMola]

She is lovely.

[BBMix]

Only kids with rampant dicks think she not hot, as if she wouldn't be the best screw some of these virgins would never have. Come on, this is a science vid, not some babe comparison debate.
