BY HANNAH MYRICK You're watching multisource video science news analysis from Newsy. A planet from another galaxy has strayed into the Milky Way, making it the first discovery of its kind. Slightly larger than Jupiter, the planet is orbiting a star 2,000 light years from earth. The star, called H-I-P 13044 is part of a stream of stars that were engulfed by the Milky Way several billion years ago. An astronomer from the UK Royal Astronomical Society explained to the BBC the significance of the discovery. Dr. Robert Massey: “There’s every reason to believe that planets are really quite widespread throughout the Universe, not just in our own galaxy…but this is the first time we’ve got hard evidence of that.” The discovery won’t just give insight into the rest of the universe; RT reports it could also give clues to the workings of own solar system. “Scientists say this alien planet is now nearing the end of its life and could help us better understand the ultimate fate of earth and the demise of our solar system.” Scientists thought they understood how planets were formed from stars, but the composition of this planet and the age of its star have astronomers questioning some of their former ideas. “According to National Geographic, the planet’s composition is radically different from other planets in the Milky Way and lack of heavy metal suggests it never should have been created.” (WHDH) Wired explains the star is older than it should be. “Also unusual is that [the star] is old enough to have exhausted its supply of hydrogen fuel… A star in this phase of evolution … has never been found to have a planet.” With all sorts of new questions being raised TIME Magazine says one thing is for sure. “The field of planetary science, which seemed so tidy and settled as recently as the 1990s, is still full of surprises.” Get more multisource science video news analysis from Newsy.
