The facts on the card
The card carries these facts from its Wikipedia article.
- Its goals were to investigate the cosmic microwave background radiation of the universe and provide measurements that would help shape the understanding of the cosmos.
- COBE's measurements provided two key pieces of evidence that supported the Big Bang theory of the universe: that the CMB has a near-perfect black-body spectrum, and that it has very faint anisotropies.
- Two of COBE's principal investigators, George F. Smoot III and John C. Mather, received the Nobel Prize in Physics in 2006 for their work on the project.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Cosmic Background Explorer article was read about 17,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 73 and blocks with 68: each hit it takes is cut by 27 %.
