The third season of our astronomy podcast is now published and available! Brand new episodes were released every Friday during March 2023 on a wide variety of podcasting platforms, giving you an unique insight into the life and work of our researchers - and into the lives and works of a few visiting researchers. The very first season of The Meridian was released back in the fall of 2021, while sec

Transcription of the zeroth episode The episode starts with background music and 24 high school students saying astronomical words like “Space missions”, "Solar wind", "The big dipper", "Galactic dynamics", "Gravitational waves", "Exoplanets", "Black holes", "Betelgeuse", "Dark energy", "Near earth asteroids", "Jupiter", "Ground based telescopes" and more. Slowly it fades to everyone saying “The

The Legacy The era of all-sky space astrometry began with the Hipparcos mission in 1989 and provided the first very accurate catalogue of apparent magnitudes, positions, parallaxes and proper motions of 120 000 bright stars at the milliarcsec (or milliarcsec per year) accuracy level. Hipparcos has now been superseded by the results of the Gaia mission. The third Gaia data release contained astrome

The development of a new space astrometry mission will require a large team of scientist, software developers and spacecraft engineers. Many lessons can be learned from the Gaia mission where DPAC (the Data Processing and Analysis Consortium) was responsible for the processing of Gaia's data and producing the Gaia Catalogue. In a similar manner a new DPAC consortium will be formed. The first task

OverviewAn obvious technological improvement to the current Gaia mission is to also go into the non-thermal Near-InfraRed (NIR) with a wavelength cutoff in the K-band allowing the new mission to probe deeper through the Galactic dust to observe the structure and kinematics of the star-forming regions in the disc, the spiral arms and the bulge region, to give model independent distances and proper

There are three main science challenges for a new all-sky astrometry mission: 1. Peering through the dust: NIR astrometry (and simultaneous photometry) is crucial for penetrating obscured regions and for observing intrinsically red objects when implemented with sufficient accuracy. Peering through the dust of the Milky Way to obtain a dense sampling of the phase space is necessary to properly stud

SpacecraftThe space telescope will be based on an off-axis f=35m Korsch telescope as used for Gaia. This design differs from Gaia's in that:the mirror surfaces are simple conics to simplify manufacturing, alignment and test.the entrance pupil is at a flat folding mirror in front of the primary instead of on the primary mirror itself.The basic design could be improved by using a segmented primary
