Liquid Helium
The Spitzer Space Telescope stays cool by using a passive cryogenic system that includes a large dewar filled with liquid helium to keep its instruments cold. The telescope is also shielded from the Sun and Earth by a sunshade to prevent it from heating up. Additionally, the telescope is designed to minimize heat-generating components and uses a combination of reflective and emissive materials to regulate temperature.
The Spitzer Space Telescope is designed to primarily observe infrared radiation, which allows it to study cool or dusty objects in space that are otherwise difficult to see with visible light telescopes. Its location in space, trailing Earth around the Sun, also enables it to maintain a consistently cold temperature for its instruments, crucial for infrared observations.
because it was so cool and everyone like it
As of today (13 Feb '14), the Hubble Space Telescope has been in space forthe past 8,696 days. It'll polish off a cool 24 yearson April 24, 2014 .
The Arecibo Telescope can detect radio waves in the radio part of the electromagnetic spectrum, particularly in the microwave frequencies. It is mainly used for radio astronomy research and for studying objects in space that emit radio signals.
The fluid that keeps the body cool is sweat.
it keeps cool in the day maybe.
it keeps the refridgerator cool
keeps it cool
it doesn't it keeps you cool! <<< i got a cotton sweater. lol It keeps me warm :P
you need to drink cool water and have life
theyre cool
