Description

The astroquarks show remarkable restraint by refusing to say that Uranus emitted a big blob of gas. Instead they keep things astronomically professional with the discovery of a plasma bubble near the 7th planet in data collected in 1986 by the venerable Voyager 2. Zooming out even further, a possible explanation for conflicting data about the expansion of the universe may be that we are living in a giant bubble 100 million light years across, give or take. See if you can match wits with Charm and Top in our Greek mythology trivia questions.
