The Unluckiest Astronomer in History (armaghplanet.com)
Whether you are a researcher gathering data, or a hobbyist taking photos from your back garden, astronomy has always required a certain amount of good luck. Instruments can be uncooperative, data can be lost or damaged, and of course there’s the ever-present threat of bad weather. This is nothing new, and the long history of astronomy is full of examples of things not quite going according to plan for even the most brilliant observers.

The disappearance of Gaia, ESA spacecraft will be turned off on 27 March 2025 (cosmos.esa.int)
On 4 March, astronomer Zhuo-Xiao Wang captured this view of the sudden disappearance of ESA’s Gaia spacecraft. After more than 11 years in space mapping the motions and properties of billions of stars, the spacecraft’s operations are coming to an end. Gaia will be switched off on 27 March 2025. During a series of final test operations, flight controllers at ESA’s ESOC mission control centre rotated Gaia, causing its sunshield to reflect more light towards Earth.
