A cloud of debris is seemingly orbiting around a star in the same path as another planet, in the first evidence of two exoplanets sharing an orbit.
In a solar system far, far away, astronomers have discovered evidence of possible"sibling" planets sharing the same orbit.
"Exotrojans are bodies that can be formed naturally inside the dust clouds trapped in the so-called Lagrangian zones, where the combined gravitational pull of the star and the planet can trap material," Balsalobre-Ruza and De Gregorio-Monsalvo said. "We found evidence of accumulation of dust of up to two times de mass of our moon in the expected location, i.e., inside the orbit of the planet PDS 70b and in the Lagrangian region L5, where Trojans are expected to be formed."

Liquid Water on Rocky Planets Could be 100 Times More LikelyAstronomers previously believed that you needed a special environment for a rocky planet to have liquid oceans on its surface, with just the right temperature and surface pressure. But a new study suggests that the radioactivity from rocks could melt water. Even if the surface is frozen, there could be oceans of water beneath the surface. Researchers suggest that there could be an average of one planet per star with these conditions in the Milky Way - 100 times more likely than previous estimates.
