I find space amazing and beautiful, but it does make my head boggle.

Scientists studying a planet orbiting one of the nearest stars, Alpha Centauri B, have found that it's only 1-3 times the size of the Earth. This implies that the planet has a rocky composition, although conditions there might not be very comfortable, as temperatures reach over 327 degrees Celsius!

It's amazing what scientists have been able to find out about our universe. But I wonder if they'll ever find somewhere just like planet Earth?

How do you feel about space exploration?


The planet tugs at its sun, which makes the star wobble slightly. Astrophysicists can infer the planet's mass from this wobble.
