1/ Happy 15th birthday, VISTA! The Visible and Infrared Survey Telescope for Astronomy, located at Paranal Observatory in #Chile, has been tirelessly mapping huge areas of the sky at infrared wavelengths. Its camera VIRCAM has captured stunning infrared vistas (see what I did there?) of our galaxy and beyond such as these: https://www.eso.org/public/images/archive/search/?facility=30

2/ VIRCAM was recently decommissioned as it will be soon replaced by 4MOST, an instrument that will take spectra of ~2400 objects spread over a wide area in one go, which means tens of millions of spectra over several years!

VIRCAM's data have a huge legacy value, and 4MOST will change so many fields. Before I switched to #scicomm I was lucky to serve as VIRCAM Instrument Scientist for a while, and also help a bit with 4MOST, so I'm happy about the past and excited for what's coming up!

3/ Addendum: if you want to compare how astronomical objects look at optical vs infrared wavelengths, over the years we've made several interactive comparisons like these:
