HAWAII: The United State (US) astronomers have find out 18 new planets same as Jupiter; with the help of twin telescopes at Hawaii.
These stars are just past the main stage of their life hence, “go away”, and are now puffing up into what’s called a sub-giant star.
“It’s the largest single announcement of planets in orbit around stars more massive than the sun, aside from the discoveries made by the Kepler mission,” John Johnson, first author on the paper, said.
The Kepler mission is a space telescope that has so far identified more than 1,200 possible planets, though the majority of those have not yet been confirmed.
To look for planets, the astronomers searched for stars of this type that wobble, which could be caused by the gravitational tug of an orbiting planet. By searching the wobbly stars’ spectra for Doppler shifts, the lengthening and contracting of wavelengths due to motion away from and toward the observer, the team found 18 planets with masses similar to Jupiter’s.
The researchers say that the findings also lend further support to the theory that planets grow from seed particles that accumulate gas and dust in a disk surrounding a newborn star.
