Quasars are extremely distant celestial bodies. Investigators using a special telescope determined that a certain quasar was emitting waves with a frequency of 1.41 x 10⁹ Hz. Using the electromagnetic spectrum provided, investigators were most likely using a telescope that detects -

• microwaves

• visible light

• x-rays

• gamma rays

The Earth’s atmosphere allows some types of electromagnetic radiation through while others may be blocked or absorbed. Due to this, astronomers developed satellites and telescopes which orbit outside of Earth’s atmosphere. The Cosmic Background Explorer (COBE) satellite took measurements from 1989 to 1993 with an effort to gather information on the background temperature in space resulting from the Big Bang. This was the first step toward confirming data gathered in the 1960’s when an Earth-bound telescope picked up static in the frequency range of 3 x 10⁸ to 3 x 10¹¹ Hz.

Which portion of the electromagnetic spectrum were astronomers detecting?

• Microwave

• Ultraviolet

• X-Ray

• Infrared
