Billions of lightyears away, gigantic clouds of hydrogen gas produce a special kind of radiation, a type of ultraviolet light known as Lyman-alpha emissions. The enormous clouds emitting the light are Lyman-alpha blobs (LABs). LABs are several times larger than our Milky Way galaxy, yet were only discovered 20 years ago.

This exoplanet, 390 light years away towards the constellation Pisces, has days when its surface temperatures exceed 2,400 Celsius, sufficiently hot to evaporate metals. Its nights, with strong winds, cool down the iron vapour so that it condenses into drops of iron.

Organic compounds called thiophenes are found on Earth in coal, crude oil and oddly enough, in white truffles, the mushroom beloved by epicureans and wild pigs. Thiophenes were also recently discovered on Mars, and astrobiologists think their presence would be consistent with the presence of early life on Mars.
