Scientists discover strange world with three suns

WASHINGTON: Scientists have discovered a new planet - located 340 light years from Earth and four times the mass of Jupiter - that orbits three stars and witnesses triple sunrises and sunsets each day, depending on the seasons, which last longer than human lifetimes. Located about 340 light years from Earth in the constellation Centaurus, HD 131399Ab is about 16 million years old, making it one
