1 On September 5, scientists analysing images taken by the Spitzer space telescope found that a particular class of stars weren't really stars. Instead, they found that these objects had many features of a planet, too. For instance, they had a surface temperature of around 450 kelvin, which is cooler than Venus's (735 kelvin) and much cooler than the Sun's (5,778 kelvin). On the other hand, these objects' interiors behave like stars'. What are these objects called?

4 According to a few studies published in late August, the heaviest stars in the Milky Way galaxy aren't formed the way other, lighter, stars are formed: by dense clouds of hydrogen collapsing under their own weight and starting _______ ______. Instead, scientists from Japan suggested that heavier stars are formed when two clouds dense clouds of hydrogen collide at high speeds, collapsing in a much stronger way and starting off with more frequent _______ ______ reactions. Fill in the blank.
5 According to analysis conducted late last August, scientists think that the largest moon of Saturn, already known to have liquid methane on its surface like Earth has liquid water, may actually harbour a 40-km thick shell of ice underground. Below this thick shell, scientists also suspect that there is a large ocean of liquid water. Which moon?
