Black holes emit tremendous amounts of energy which result in astronomers using many different means of technology to gather information. Instruments such as the GALEX satellite and Spitzer Space Telescope use different parts of the electromagnetic spectrum to gather data about these strange celestial objects. To view black holes, the GALEX typically operates at a frequency of about 1.3 X 10¹⁵ Hz while the Spitzer Space Telescope operates at 2.2 X 10¹² Hz.

Which two portions of the electromagnetic spectrum are astronomers using to detect information about black holes?

• Ultraviolet and X-Ray

• Gamma Ray and X-Ray

• Ultraviolet and Infrared

• Infrared and Radio

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
