Dr. Herrera Martin, the paper's lead author, describes the planet-finding discovery as incredibly rare. 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. 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.

The discovery of the super-Earth was made thanks to an astronomical phenomenon known as gravitational microlensing. This particular microlensing event was observed during 2018 and designated OGLE-2018-BLG-0677. and Terms of Use.

Astronomers at the University of Canterbury (UC) have found an incredibly rare new Super-Earth planet towards the centre of the galaxy. NASA has racked up some intriguing super-Earth discoveries in recent years, including the potentially habitable Kepler 62f.

Astronomers at the University of Canterbury (UC) have found an incredibly rare new Super-Earth planet towards the centre of the galaxy. "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. Dr. Herrera Martin explains the planet was discovered using a technique called gravitational microlensing. Toward the center of our galaxy, in a star system far away, is a planet with features that remind us of home. The microlensing effect is rare, with only about one in a million stars in the galaxy being affected at any given time. The GJ 357 system has three planets that we know of.

A whole new category of planets, Super Earths are quite common in our galaxy. On Nov. 27, 1885, an astronomer made the first known photograph of a meteor. Lead researchers in the discovery, astronomers Dr. Antonio Herrera Martin and Associate Professor Michael Albrow, both of UC's School of Physical and Chemical Sciences in the College of Science, are part of an international team of astronomers who collaborated on the Super-Earth research. Moreover, its mass of 5 Earth masses increases the possibility that the planet is a mini-Neptune instead of a super-Earth. For scale, Earth is about 25,000 light-years away from the galactic center. The planet is about 1,400 light-years away from the Solar System.
