| Getting to know super-Earths: Using Hubble to study mysterious exoplanet Posted: 15 Oct 2014 12:25 PM PDT Results from NASA's Kepler mission have indicated that the most common planets in the galaxy are super-Earths -- those that are bigger than Earth but smaller than Neptune. We have no examples of these planets in our own solar system, so astronomers are using space telescopes to try to find out more about these worlds. Most recently they used Hubble to study the planet HD 97658b, in the constellation Leo. |
| Astronomers spot faraway Uranus-like planet: First 'ice giant' planet found in another solar system Posted: 15 Oct 2014 07:13 AM PDT Our view of other solar systems just got a little more familiar, with the discovery of a planet 25,000 light-years away that resembles our own Uranus. Astronomers have discovered hundreds of planets around the Milky Way, including rocky planets similar to Earth and gas planets similar to Jupiter. But there is a third type of planet in our solar system -- part gas, part ice -- and this is the first time anyone has spotted a twin for our so-called "ice giant" planets, Uranus and Neptune. |
