When it comes to finding life on other planets, a warm, wet world bubbling with a complex soup of chemicals might not be enough.
belt and the asteroids that share its orbit. But its immense gravity can also disrupt the orbits of those smaller bodies, flinging them towards the inner Solar System. Early in the system's history, Jupiter was likely instrumental in helping those rocks reach Earth.
"Jupiter analogues form preferentially around stars with metallicities close to solar, and strikingly, potentially habitable low-mass planets could be common around stars that host a cold Jupiter,"an international team of astronomers led by Thiago Ferreira of the University of Sao Paulo in Brazil. Since 2014, astronomers have been using the High Accuracy Radial velocity Planet Searcher at the European Southern Observatory's La Silla 3.6 meter telescope in the Chilean Atacama Desert to search for planets around stars that are similar to the Sun.
When Ferreira and his colleagues analyzed the light from HIP 104045, they found evidence of not one world, but two.
