Molecular cloud, an Uncommon card
A molecular cloud, sometimes called a stellar nursery if star formation is occurring within, is a type of interstellar cloud of which the density and size permit absorption nebulae, the formation of molecules, and the formation of H II regions.

Power 145 (ATK + DEF): stronger than 75 % of WikiCards cards.
The facts on the card
The card carries these facts from its Wikipedia article.
- This is in contrast to other areas of the interstellar medium that contain predominantly ionized gas.
- Molecular hydrogen is difficult to detect by infrared and radio observations, so the molecule most often used to determine the presence of H2 is carbon monoxide.
- The ratio between CO luminosity and H2 mass is thought to be constant, although there are reasons to doubt this assumption in observations of some other galaxies.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Molecular cloud article was read about 58,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 71 and blocks with 74: each hit it takes is cut by 30 %.
How to get Molecular cloud
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
