Are you getting our news updates? This month we feature #RCSAFellows, #Scialog, and #CottrellScholars news, plus a look back at two catalytic investments in major telescope projects that have helped advance modern astronomy. Join our email list!

📃Scientific paper: A Chronological History of X-Ray Astronomy Missions Abstract: In this chapter, we briefly review the history of X-ray astronomy through its missions. We follow a temporal development, from the first instruments onboard rockets and balloons to the most recent and complex space missions. We intend to provide the reader with detailed information and references on the many missions and instruments that have contributed to the success of the exploration of the X-ray universe. We have not included missions that are still operating, providing the worldwide community with high-quality observations. Specific chapters for these missions are included in a dedicated section of the handbook. Discover the rest of the scientific article on es/iode ➡️https://etcse.fr/mW2FD

#OnThisDay, January 3, 1920, Edwin Hubble forever altered the course of astronomy and basic science by identifying Cepheid variable stars in the Andromeda Nebula using the 100-inch Hooker telescope. His revelation that Andromeda was a separate galaxy expanded the very boundaries of our universe. This fundamental discovery underscores the incredible impact of basic science on our understanding of the cosmos.

FROM SCIENCE AND ASTRONOMY: You are looking at the clearest image ever taken of Venus.

Revisiting myself two year back when I was exploring space technologies and theoretical astronomy. I participated in this year long olympiad, ISSO, Indian Space Science Olympiad conducted by Edumithra Event Mangement. I learnt many concepts regarding astronomy. Out of which, the black hole theory, Quasars and stellar formation are some things which intrigued me the most. Finally after a lot of research work and 3 long rounds over the span of an year I managed to secure AIR 12 rank. ☺️✌️ trying to achieve more and pursue my current interest computer science in harmony with astronomy. #isso #space #astronomy #olympiad #rockets #science #nebula

ASTRO: A Collaborative Platform for Space Science Research ASTRO is a specialized website designed for one of the leading institutes in astronomy and space sciences. It serves as a hub for accessing and sharing research, offering a space where users can find detailed information and engage with ideas. Key Features: Showcase Research: Display completed projects with brief descriptions, project goals, team details, and achievements on dedicated landing pages. Collaborative Space: Facilitate peer recommendations and discussions to advance research. Intuitive Design: Features a user-friendly layout and navigation, making it easy to interact with research materials and illustrations.

📃Scientific paper: Astronomy, Doughnuts, and Carrying Capacity Abstract: I examine the applicability of ecological concepts in discussing issues related to space environmentalism. Terms such as "ecosystem"", "carrying capacity"", and "tipping point" are either ambiguous or well defined but not applicable to orbital space and its contents; using such terms uncritically may cause more confusion than enlightenment. On the other hand, it may well be fruitful to adopt the approach of the Planetary Boundaries Framework, defining trackable metrics that capture the damage to the space environment. I argue that the key metric is simply the number of Anthropogenic Space Objects (ASOs), rather than for example their reflectivity, which is currently doubling every 1.7 years; we are heading towards degree scale separation. Overcrowding of the sky is a problem astronomers and satellite operators have in common. ;Comment: Seven pages, two figures. To be published in "Astronomy and Satellite Constellations: Pathways Forward", proceedings of IAU Symposium 385, eds. C.Walker, D.Turnshek, P.Grimley, D.Galadi-Enriquez, and M.Aube. For consistency with IAU policy, the version posted here is the submitted text under review Continued on ES/IODE ➡️ https://etcse.fr/hzD ------- If you find this interesting, feel free to follow, comment and share. We need your help to enhance our visibility, so that our platform continues to serve you.

This is a fantastic overview from the IAU CPS on the impacts of increasing Low Earth Orbit (LEO) satellite constellation deployments on ground based optical and radio astronomy, and the need to protect them along with access to the natural night sky for all of humanity. The precautionary principle puts the onus on us as space engineers to understand the wider impacts of our activities and mitigate them where necessary. That way we can ensure we achieve the amazing benefits possible from our technology without destroying other vital areas of activity and the wider space environment. To help in this there are some really valuable recommendations that I encourage any spacecraft or network development team to consider as a core element in their design process. As part my own research The University of Manchester into the development of direct to handset space based extensions to the terrestrial mobile communications network I am now looking at how access to lower orbits will enable smaller, lower power spacecraft. These can then be dimmer and quieter across a range of frequencies and more rapidly traverse the field of view, minimising or removing these terrestrial impacts whilst still enabling ubiquitous, high speed, low latency connectivity. #DarkandQuietSkies #SpaceTechnology #Astronomy #SpaceEngineering #SpaceSustainability
