Question

The galaxy __________ was initially discovered with NASA's Spitzer Space Telescope in infrared light and is believed to be at least 9 billion years old.

• A. ANDROMEDA
• B. COSMOS REDSHIFT
• C. SAGE0536AGN
• D. SUNFLOWER

Answer 1

The Correct Option is A

The correct answer is ANDROMEDA. The Andromeda Galaxy, also known as M31, is one of the most well-known galaxies and was discovered long before the advent of modern telescopes; however, the question might be hinting at a significant discovery related to it via NASA's Spitzer Space Telescope in infrared light. Here is some context:

• The Andromeda Galaxy is a spiral galaxy approximately 2.537 million light-years from Earth.
• It is the nearest major galaxy to the Milky Way and has been the subject of much study due to its proximity.
• The galaxy was known for centuries, but modern telescopic technology, like the Spitzer Space Telescope, has allowed astronomers to study its characteristics in wavelengths such as infrared, revealing more about its structure, stars, and interstellar matter.

Considering the options and the given context about discovery in infrared light, Andromeda is the most fitting choice.
