The first close-up picture of a star outside our own galaxy (eso.org)
This is an image of the star WOH G64, taken by the GRAVITY instrument on the European Southern Observatory’s Very Large Telescope Interferometer (ESO’s VLTI). This is the first close-up picture of a star outside our own galaxy, the Milky Way. The star is located in the Large Magellanic Cloud, over 160 000 light-years away. The bright oval at the centre of this image is a dusty cocoon that enshrouds the star.

Probing unknown unknowns: A new generation of telescopes (mappingignorance.org)
In recent decades, we’ve learnt huge amounts about the universe and its history. The rapidly developing technology of telescopes – both on Earth and in space – has been a key part of this process, and those that are due to start operating over the next two decades should push the boundaries of our understanding of cosmology much further.
