阅读原文Astronomers find strongest evidence yet that Betelgeuse has a companion
At long last, astronomers have firm evidence that Betelgeuse, one of the most famous stars in the night sky, is not alone. Using the European Southern Observatory’s Very Large Telescope (ESO's VLT), a team led by French researcher Miguel Montargès obtained the clearest image ever of what likely is Betelgeuse B, the star orbiting Betelgeuse. “This is the conclusion of a century-long quest,” says Montargès.
阅读原文New ‘exomoon’ detection challenges cosmic labels
Observations made with the European Southern Observatory’s Very Large Telescope (ESO’s VLT) have revealed evidence for a moon-like object in the CD-35 2722 system. Unlike moons in our Solar System, the newly found object does not orbit a planet, raising questions about what to name it. Instead, it circles a brown dwarf, an object larger than a planet, that orbits the CD-35 2722 star. If confirmed, this could be the first ‘moon’ discovered outside our Solar System.
