Answer to Question 1

starburst

Answer to Question 2

The greatest advantage is the lack of seeing distortion. A telescope in space is not limited to Earth's atmospheric turbulence and transparency. Space-bound telescopes can collect radiation that is usually absorbed by Earth's atmosphere.

HST: can detect fine detail, and because it concentrates light into sharp images, can detect extremely faint objects

JWST (to be launched): avoids interference from Earth's strong infrared glow

Chandra: operates in an orbit that extends a third of the way to the Moon so that it spends 85 percent of the time above the belts of charged particles surrounding the Earth that would produce noise in its detectors
