Scientists spot 'one in a million' super-Earth
Toward the center of our galaxy, in a star system far away, is a planet with features that remind us of home.
50 exoplanets discovered in deep space by advanced artificial intelligence
"Extra-solar planet" is another term for exoplanet, which describes a planet located outside our solar system. We only have artists' impressions of what these planets might look like, but they continue to fuel our curiosity as we seek out distant worlds that feel familiar
The super-Earth discovery was a fortuitous event that UC described as "one in a million."
The astronomers used a gravitational microlensing technique to spot the planet. "The combined gravity of the planet and its host star caused the light from a more distant background star to be magnified in a particular way. We used telescopes distributed around the world to measure the light-bending effect," said UC astronomer Antonio Herrera Martin.

The researchers published their findings in The Astronomical Journal this month.

There's a lot of hope wrapped up in a term like "super-Earth," but there are no guarantees a planet in this category will look anything like our own. NASA describes super-Earths as "up to 10 times more massive than Earth," but says they may vary in composition from water worlds to icy planets to ones made mainly of gas.
