Telescope limitation could reveal exoplanets (Jun 22)

Astronomers in the UK, the US and Germany are the first to use a new
data-analysis technique that could boost a telescope’s ability to search
for “exoplanets” — planets outside our solar system. Surprisingly, the
technique makes clever use of the diffraction of light, an effect that
had previously prevented telescopes from resolving many exoplanets from
their parent stars. The astronomers used the technique to get a combined
image and spectrum of a faint star 48 light-years away (Astrophys. J. in
press).
