An Extragalactic Extrasolar Planet?
In " Extrasolar Planets Thwart Cosmic Evolution ", we looked at three articles by astrophysicist Dr. Jason Lisle. He discussed the history of exoplanets, the methods used for detection, how astronomers know their composition, and more. Those planets are within our own galaxy. Detecting them is fascinating enough, but prepare to be impressed again because there is a strong possibility that an exoplanet outside our galaxy has been found. Those fun-loving astronomers have given it the whimsical name of M51-ULS-1b. This discovery is quite interesting. X-ray: NASA /CXC/SAO/R. DiStefano, et al.; Optical: NASA/ESA/STScI/Grendler; Illustration: NASA/CXC/M.Weiss (Usage does not imply endorsement of site contents) This is a bigly-huge distance away, and the detection is reminiscent of that used for discovering the first exoplanets (this method may lead to further discoveries out there, thataway). In both cases, planets are around massive objects, but the latest one has quite a bit happ
