The facts on the card
The card carries these facts from its Wikipedia article.
- With a standard optical telescope, the background space between stars and galaxies is almost completely dark.
- However, a sufficiently sensitive radio telescope detects a faint background glow that is almost uniform and is not associated with any star, galaxy, or other object.
- This glow is strongest in the microwave region of the electromagnetic spectrum.
Why it is Rare
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Cosmic microwave background article was read about 310,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 87 and blocks with 95: each hit it takes is cut by 38 %.
