NASA finds first super-Earth exoplanet with an atmosphere
Astrophysicists at NASA have found a super-Earth exoplanet dubbed as 55 Cancri e with an atmosphere for the first time.
These NASA astrophysicists were working with the European Space Agency (ESA) and the University College London.
Key facts
- 55 Cancri e was discovered using Hubble telescope’s Wide Field Camera 3 (WFC3).
- It is located around 40 light years away and eight times bigger than earth.
- It is located extremely close to its planet star, which heats its surface to a staggering 2,000 degrees Celcius making it only known super-Earth with such a high temperature.
- 55 Cancri e’s atmosphere largely consists of hydrogen (H) and helium (He) similar to gas giant planets with no traces of water and doesn’t sustain life.
Super-earths: They are merely rocky planets that are larger than the Earth. They’re widely supposed to be the most common type of rocky planet in the galaxy.
