Comet C/2023 A3 brightens SOHO’s week

From 7 until 13 October 2024, ESA/NASA’s SOHO spacecraft recorded Comet C/2023 A3 (Tsuchinshan–ATLAS), the second brightest comet it has ever seen. Meanwhile, large amounts of material were being spewed out by the Sun (covered in the centre), and planet Mercury is visible to the left.
The comet’s nucleus is clearly visible, surrounded by a dusty coma and trailing an impressively long tail. SOHO sees the large dust tail edge-on, curving in on itself as it is pushed outward by solar wind.
At the end of the video you can also see a rare phenomenon known as an ‘
Contract secures build for ESA’s Harmony mission

ESA has awarded a contract valued at over €280 million to OHB in Germany to build ESA’s two Harmony Earth Explorer satellites.
This innovative research mission will provide valuable new data on various Earth processes, from shifts in the shape of the land surface caused by earthquakes and volcanic activity to insights into glacier movement. Additionally, it will enhance our understanding of the interactions between the upper ocean and lower atmosphere, all of which will contribute to a deeper comprehension of Earth's dynamic systems.
