Making a “Mega-Telescope” for Exoplanets
How can we combine multiple telescopes to learn about exoplanets? Interferometry!

Today’s authors take a multi-faceted approach to characterising a benchmark subgiant star using asteroseismology, interferometry, and spectroscopy.
Continuing on the thread from Friday’s post, I also attended the recent SPIE meeting. Here are my thoughts, as someone who is on the science side of the field, on the engineering and instrumentation conference.
Radio observations of the diffracted shadow cast by an asteroid can be used to nail down its location and determine its size and shape.
The first stellar intensity interferometry experiment in decades!
ALMA has taken a brand-new image of Fomalhaut’s famous debris disk. What can we learn from it?
