Carl Engelking on Discover Magazine’s D-brief blog is reporting the possibility there’s an Earth-like planet orbiting in the Proxima Centauri system – the closest such system to our own, at 4+ light years.
The ante for hyping a new exoplanet discovery is a little higher these days, but if rumors are true, this one makes the grade: astrophysicists from the European Southern Observatory (ESO) plan to announce they’ve spotted an Earth-like exoplanet orbiting the nearest star, Proxima Centauri, in its habitable zone. This, according to an anonymous source quoted in a report that appeared Friday in Der Spiegel.
“The still nameless planet is believed to be Earth-like and orbits at a distance to Proxima Centauri that could allow it to have liquid water on its surface—an important requirement for the emergence of life,” the source said.
Carl throws a little cold water on the flames of curiosity:
Although media reports say the rumored planet orbits in a region that’s potentially favorable for life, these smaller stars are less stable, and Proxima Centauri is known to have violent flares at times. Its occasional tantrums have made astronomers skeptical of finding life around red dwarf stars in the past.
