Say hello to your new neighbor. Proxima Centauri, the closest star to the Sun, has an Earth-mass planet in the habitable zone, but it wasn’t easy to find, and it’s in a bit of a dangerous place.
The James Webb Space Telescope will be the largest space observatory built to date. The authors of today’s paper suggest one possible use for the giant new telescope: Searching for signs of life on other planets.
Orbital stability of high-mass multi-planet systems is scrutinized in comparison to their low-mass counterparts.
It’s our innate human instinct to uncover mysteries. Find out how Spitzer observations of 55 Cnc e are raising new questions and creating new mysteries that could be addressed with the next generation of ground and space based missions.
White dwarfs, the tiny, burnt out cores that stars like the Sun leave behind when they run out of fuel, are a surprisingly ideal place to look for potentially habitable planets. The authors of today’s paper have checked to see if we haven’t already found one, entirely by accident.
Using a laser we can carefully edit the telltale signs of the Earth’s presence, hiding ourselves away or announcing our presence to other life in the universe. But doing so may be fraught with unknowable consequences that we can never undo. Maybe it’s best to just stay behind the galactic sofa.
