The new discovery gives better insight into the formation of planets and gives people more opportunities to find Earth-like worlds.
Using two of the most advanced telescope systems, the Keck infrared-optical telescope (located in Hawaii – USA) and the Hubble Space Telescope, scientists analyzed white dwarf spectral data from 18 systems of ‘exoplanets located 456 light years from Earth.
Lead author of the study – scientist Siyi Xu (Gemini Observatory, Hawaii – USA) said he found many “earth materials” on these white dwarfs, which are elements that can be found on earth and that make up our planet.
