"These experiments detect around 3000 microlensing events each year, the majority of which are due to lensing by single stars," the paper's co-author Associate Professor Albrow notes. A planet comparable to Earth's size and orbit has been discovered. To find out more, read our Privacy Policy. Located in the outer edge of its host star's "habitable zone," scientists believe that this super-Earth could have water on its surface. However, what makes this world so remarkable is the resulting low density derived from these measurements. Preprint version available at arxiv.org/abs/2003.02983, Journal information: Astronomers at the University of Canterbury (UC) have found an incredibly rare new Super-Earth planet towards the centre of the galaxy.

Calling it "incredibly rare," New Zealand astronomers say the planet "is one of only a handful that have been discovered with both size and orbit comparable to that of Earth," according to a statement. Using the solar system as a point of reference, the host star is about 10% the mass of our Sun, and the planet would have a mass somewhere between that of Earth and Neptune, and would orbit at a location between Venus and Earth from the parent star. It was independently detected by the Optical Gravitational Lensing Experiment (OGLE) using a telescope in Chile, and the Korea Microlensing Telescope Network (KMTNet) to which the UC astronomers belong, using three identical telescopes in Chile, Australia, and South Africa.

The planet is one of only a handful that have been discovered with both size and orbit comparable to that of Earth. Study lead author Antonia Herrera-Martin, also of the University of Canterbury, said the planet was discovered using a technique called gravitational microlensing. An artist’s rendering of the Proxima Centauri system shows the newly discovered exoplanet Proxima c (on the right), which orbits its host star in about 5.2 years. The nearest single star to the Sun hosts an exoplanet at least 3.2 times as massive as Earth — a so-called super-Earth. Due to the host star having a smaller mass than our Sun, the planet would have a 'year' of approximately 617 days. Identify the news topics you want to see and prioritize an order. "We used telescopes distributed around the world to measure the light-bending effect.”. The microlensing effect is rare, with only about one in a million stars in the galaxy being affected at any given time. The finding is one of only a handful of super-Earths discovered to date. The system also comprises the … “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," he said. Not so fast. Researchers have found a Super-Earth exoplanet they describe as "one in a million" in deep space. The newly discovered exoplanets, GJ887b and GJ887c, are so-called super-Earths, meaning their size ranks roughly between our planet and Neptune.

To get a … A new ‘Super-Earth’ planet orbiting Proxima Centauri, which is the Sun’s nearest neighbouring star, has been discovered by scientists, who published the … The … According to the study, the super-Earth's host star is about 10% the mass of our sun, and the planet would have a mass somewhere between that of Earth and Neptune. An international team of astronomers has found 60 new planets orbiting stars close to Earth’s solar system, including a rocky “super Earth.” In July 2018, the discovery of 40 Eridani b was announced. I would like to subscribe to Science X Newsletter. Herrera-Martin A., et al., 2020, OGLE-2018-BLG-0677Lb: A Super-Earth Near the Galactic Bulge, Astronomical Journal, 159, 256. … With global reach of over 5 million monthly readers and featuring dedicated websites for hard sciences, technology, smedical research and health news, Astronomers at New Zealand's University of Canterbury (UC) discovered a particularly rare super-Earth. GJ 536 b is more than five times the size of Earth, making it a 'super-Earth' Two new "super Earths" – planets larger than Earth but smaller than Neptune, about which little is known – were discovered using a machine-learning algorithm. In addition, this type of observation does not repeat, and the probabilities of catching a planet at the same time are extremely low, Martin said. Another difference: Because the host star has a smaller mass than our sun, the planet would have a "year" of about 617 days. The research about the discovery was published recently in a study in the Astronomical Journal. The smaller Proxima b, shown on the left, was discovered in 2016. Note: Dr. Herrera Martin, the paper's lead author, describes the planet-finding discovery as incredibly rare. Optional (only if you want to be contacted back). The planet is one of only a handful that have been discovered with both size and orbit comparable to that of Earth.

Those properties place 55 Cancri e in the "super-Earth" class of exoplanets, a few dozen of which have been found. The planet named GJ 357 d, is six times larger than Earth. The new observations with Spitzer reveal 55 Cancri e to have a mass 7.8 times and a radius just over twice that of Earth. "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. New super-Earth is discovered nearby: Exoplanet is found orbiting a star 33 light years away - and there could be more.

Dana Jacobson reports. the Science X network is one of the largest online communities for science-minded people. The planet-hunters' research has recently been published in the Astronomical Journal. Another Super-Earth, K2-155d, is discovered. Potentially habitable super-Earth discovered 31 lightyears away, a new planet has been found by NASA's Transiting Exoplanet Survey Satellite. Around an M-type dwarf known as GJ 357, researchers have spotted a new system of planets. Simmering just outside our solar system, a hot new super-Earth has been discovered lurking in the HD 164922 planetary system roughly 72 light years off in the constellation of Hercules. It would also orbit its star at a location between Venus and Earth. "Dr. Herrera Martin first noticed that there was an unusual shape to the light output from this event, and undertook months of computational analysis that resulted in the conclusion that this event was due to a star with a low-mass planet.

As for life or water, however, study authors say we should not get our hopes up: "Although it’s not too much bigger than Earth, and orbiting its star at a similar distance, this planet would be very cold because its star is smaller than the sun and emits much less light,"  study co-author Michael Abrow of New Zealand's University of Canterbury told USA TODAY.
