Space Facts: Part 2 - Dark Matter, Comet 67P and Different types of Space Telescopes

-

1. Dark Matter:

Dark matter is made up of WIMP or AXION particles, WIMP means Weakly Intensive Massive Particles.

2. Comet: 67 P

67P/Churyumov Gerasimenkov comet takes 6.5 earth years to complete one revolution of solar system. Rosetta is the first satellite to reach comet's orbit. Rosetta is spacecraft from ESA (European Space Agency) which contained Rover and Orbiter. Comets generally come from Cloud of Urt or Kuiper Belt.


3. Space Telescopes and Observatories:

There are different types of space observatories made by different space organizations like NASA, ESA, JAXA, ROSCOSMO, CNSA, ISRO, etc.

 X-Ray: Chandra X-Ray Spacecraft
Gravity wave telescope:  BICEP 2
Microwave: Wisconsin Microwave Aniastropy Probe, Cosmic Microwave Background Explorer (COBE)
Gamma Ray,Neutrino observatory, Optical telescope, etc.
