1. Astronomers have discovered a planet where it rains glass (silicate) sideways, in howling 7,000km-per-hour winds. This gives the planet a blue hue. It is 63 light-years from us.

2. NASA has discovered a “waterworld” planet 40 light-years away that may contain exotic materials such as “hot ice” and “superfluid water.”

3. 51 Pegasi B is a gas giant located 440 light years away from us which has temperatures reaching 1000 to 2000°C. Due to such high temperatures, it rains iron there.

4. Jupiter is shrinking at the rate of about 2 cm each year because the planet radiates more heat than it receives from the Sun.

5. Scientists have estimated that there are nearly 2 billion earth-like planets in the Milky Way alone.
