Tracking a star’s movement by measuring its age and chemistry
Potentially habitable super-Earth is a prime target for atmospheric study
Best image of Alpha Centauri A and B
The NASA/ESA Hubble Space Telescope has given us this stunning view of the closest bright stars Alpha Centauri A (on the left) and Alpha Centauri B (on the right), at a distance of 4.3 light-years from the Earth. The Alpha Centauri group is completed by a faint red dwarf, Proxima Centauri (not shown), recently revealed to possess an Earth-like planet orbiting in its habitable zone.
