hubble

_______________

Answer 2

Chandra is an odd one.

Why Chandra is the odd one here?

Newtonian, Cassegrain, Hubble, Chandra are types of telescopes.

Newtonian:

• Newtonian telescopes are reflectors. To concentrate light rays objects, scientists use a reflector instead of a lens. Newtonian is visible radiation.

Cassegrain:

• The Cassegrain telescope is a reflective telescope wherein light strikes a large concave paraboloid reflector and is mirrored onto a tiny convex hyperboloid mirror. Cassegrain is also visible radiation.

Hubble:

• Hubble telescope is also visible radiation.

Chandra:

• Chandra telescope is X-ray detect. The Chandra X-ray Telescope is indeed a NASA telescope that is specifically built to detect X-ray radiation from very hot parts of the Universe including such burst stars, galaxy clusters, and materials surrounding black holes.

Hence, Chandra is the odd one out.
