🔭 The IAC leads the first results from #NIRPS, the new infrared planet hunter.
🌍 Detects Earth-like planets in IR for the first time with <1 m/s precision.
✅ Confirms a planet with 1/3 Earth's mass orbiting Proxima Centauri.
📄 5 papers in A&A

Wow! “a decommissioning strategy that involved systematically picking apart and disabling the layers of redundancy that have safeguarded Gaia for so long, because we don’t want it to reactivate in the future and begin transmitting again if its solar panels find sunlight”
Farewell, Gaia! Spacecraft Operations Manager Peter Collins confirms that Gaia has fallen silent, having been successfully passivated and switched off after more than a decade spent mapping the cosmos.

Gaia essay 191. Extinction. Extinction is important in determining stellar parameters from spectral modelling, and central in describing the distribution of gas and dust in the solar neighbourhood. I will summarise what has been measured with Gaia so far

While training undergraduates, a special sample of #GaiaData was obtained... and what, to their wondering eyes, appeared? An interesting duo: an ultracool subdwarf with a white dwarf companion, and they belong to the halo! Story: cosmos.esa.int/web/gaia/iow_… youtube.com/shorts/idEtH2Dis…

This is Buddo. The earliest depiction of a human figure found anywhere in the British Isles. It is made out of whale bone and can be found in the Stromness Museum on Orkney. At 4,900 years old it comes from a time when mammoths still walked the Earth 🦣 . #neolithic #Orkney
