Astronomy Quiz 2

Astronomical objects always look the same in the different wavelengths of light.

False

Hubble Space Telescope cannot detect infrared light.

False

NASA launched the Hubble Space telescope into space to get much closer to the stars.

False

Deployed _____________________ from the space shuttle Discovery, Hubble is one of the largest and most complex satellites ever built.

April 25, 1990

As Hubble Space telescope orbits the Earth, it passes through Earth shadow, where temperatures plunge to 250 degrees below zero. When Hubble swings back into sunlight, outside temperatures skyrocket to above boiling. The extreme temperature shift is almost like traveling from Antarctica to the Sahara Desert within minutes.

True

Finished color images are actually combinations of two or more black-and-white exposures to which color has been added during image processing.

True

Hubble Space Telescope doesn't use color film.

True

In 1929, Edwin Hubble determined that the more distant the galaxy from Earth, the faster it appears to move away. Known as Hubble s Law, this discovery is the foundation of the Big Bang theory. The theory says that the universe began after a huge cosmic explosion and has been expanding ever since.

True

Once Hubble gathers pictures and data on celestial objects, its computers turn the information into long strings of numbers that are beamed to Earth as radio signals. This information streams through a series of satellite relays to the Goddard Space Flight Center.

True

To make an observation, Hubble must find a pair of bright stars called guide stars near each target planet, star, or galaxy.

True
