Mysterious planet discovered outside solar system

Scientists have found evidence of the first ever planetary-mass object beyond our solar system. And it’s huge! Probably a dozen times bigger than Jupiter, according to the researchers at the National Radio Astronomy Observatory. They’re calling it a ‘rogue’ planet because it appears to be traveling through space without any kind of orbit around a parent star. ‘This object is right at the boundary between a planet and a brown dwarf, or ‘failed star,’ and is giving us some surprises that can potentially help us…

Artificial intelligence finds solar system with 8 planets like ours

MIAMI: A solar system with as many planets as our own has been discovered with the help of NASA's Kepler space telescope and artificial intelligence, the US space agency said Thursday. "Our solar system now is tied for most number of planets around a single star," NASA said in a statement. However, none of the planets are expected to be hospitable to life. The eight-planet system -- the largest known outside of ours -- orbits a star called Kepler 90 some 2,545 light-years away. "The Kepler-90 star system is like…

Move over Saturn! a dwarf planet has a ring to it

PARIS: Move over Saturn! Scientists have found a ring around an unassuming mini-planet in our Solar System to debunk the theory that only giant planets can be so adorned. The planet, dubbed Haumea, orbits the Sun far beyond Neptune -- the eighth and furthest recognised "full" planet in our star system since Pluto was downgraded to dwarf status in 2006. About eight billion kilometres (five billion miles) from the Sun, Haumea spins rapidly on its own axis, and has a flattened, cigar-like shape. It takes 285 years to…

WATCH: NASA discovers seven Earth-like planets revolving around a single star

Researchers announced Wednesday the stunning discovery of seven Earth-like planets orbiting a small star in our galaxy, opening up the most promising hunting ground so far for life beyond the Solar System. SCROLL DOWN FOR MORE VIDEOS All seven roughly match the size and mass of our own planet and are almost certainly rocky, and three are perfectly perched to harbour life-nurturing oceans of water, they reported in the journal Nature.

NASA announces two missions to study early solar system

WASHINGTON: The US space agency NASA on Wednesday announced two unmanned missions to asteroids designed to study one of the earliest eras in the history of the solar system. They have been dubbed Lucy and Psyche, and NASA hopes to launch them in 2021 and 2023, respectively. The period NASA wants to learn more about is an era less than 10 million years after the birth of the sun. The Lucy mission -- named for a famous, critical hominin fossil set found in Ethiopia in 1974 -- will involve sending a robotic spacecraft…
