Astronomers: Two Goldilocks Exoplanets in Gliese 581 System Just Cosmic Illusion

The upper image shows the location of six candidate exoplanets believed to orbit Gliese 581 as of 2010. Blue indicates candidate exoplanets in the habitable zone. The bottom image shows the location of the three exoplanets remaining in 2014. Image credit: NASA / Penn State University.

Astronomers led by Dr Paul Robertson of the Pennsylvania State University say that signals that were suspected to be coming from two Earth-like exoplanets orbiting in the habitable zone of a nearby star called Gliese 581 actually are created by activity within the star itself. The upper image shows the location of six candidate exoplanets believed to orbit Gliese 581 as of 2010. Blue indicates candidate exoplanets in the habitable zone. The bottom...

This image shows the Tadpole galaxy (Arp 188), a disrupted barred spiral galaxy located 420 million light-years from our planet. Material stripped from the galaxy during its collision with a smaller galaxy (seen in the upper left corner of the larger interaction partner) forms a long tidal tail. Young blue stars, star clusters and tidal dwarf galaxies are born in the tidal debris. These objects move in a common direction within a plane defined by the orientation and motion of their tidal tail. A similar galaxy interaction might have occurred in the Local Group in the past, which could explain the distribution of dwarf galaxies in co-rotating planes. Image credit: H. Ford, JHU / M.
