18. Gamma ray telescopes can detect light from the most violent explosions in the universe, probably caused by stars collapsing into black holes. If a gamma ray burst occurred within 6,000 light-years of us, we’ d all be fried.
19. Weirdest telescope ever? In the 1960s physicist Raymond Davis Jr. used 100,000 gallons of dry-cleaning fluid to detect invisble neutrino particles as they stream from the sun.
20. Davis’ s bizarre telescope worked, revealing fundamental new physics and netting him a Nobel in 2002.

The James Webb Space Telescope( sometimes called JWST) is an orbiting infrared observatory that will complement and extend the discoveries of the Hubble Space Telescope, with longer wavelength coverage and greatly improved sensitivity. The longer wavelengths enable the Webb telescope to look much closer to the beginning of time and to hunt for the unobserved formation of the first galaxies, as well as to look inside dust clouds where stars and planetary systems are forming today.
