#NEWS: We have issued our first recommendations paper urging action to address the impact of satellite constellations on astronomy 🛰️. 🔗 Read it here: https://loom.ly/n-5Iw6Y The 30-page paper is the result of 18 months’ work by experts including astronomers, industry representatives and policy advisors. It proposes measures and mitigation strategies for different stakeholders, including calling for satellite operators to adopt voluntary mitigations, and outlines the regulations needed at both the national and international level.

Today is International Astronomy Day Did you know UV imaging spectrographs are used to observe UV wavelengths around other planets? This allows scientists to understand the composition of planetary atmospheres and even ‘see’ new features on the dark side of worlds. #uvspace #uvastronomy #uvfunfacts #uvlamps #spectrographs

🌌 The days are getting shorter, and the nights are growing longer. Autumn brings with it an extraordinary opportunity: stargazing! The best time to do it is now, with the right lenses. With darkness descending earlier, the stars and planets reveal themselves in all their beauty. Astronomy becomes a captivating passion, and to explore the cosmos, high-quality optical systems are essential. Lobre s.r.l. lenses are the key to celestial exploration. Our expertise in producing high-quality optical lenses makes every observation an extraordinary experience, with sharp and detailed images. We offer customized lenses to suit the specific needs of telescope manufacturers. This allows for the creation of telescopes suitable for a variety of purposes, from planetary observation to deep-space astronomy. Lobre has collaborated with research institutions in the field of astronomy, including INAF, demonstrating the trust our brand inspires in the realm of space exploration. 🔭 #lobre #opticalsystems #lens #coating #microscopes #precisionlens 

Australian astronomers get a clearer picture of the high energy universe via eROSITA’s first all-sky survey! Data from the first all-sky survey by the X-ray imaging telescope eROSITA has been released, yielding the largest X-ray catalogue ever published. A series of scientific papers were also released along with the data, including two led by Australian researchers Dr Adelle Goodwin and PhD student Silvia Mantovanini from ICRAR (International Centre for Radio Astronomy Research), Curtin University. Lead investigators Dr Goodwin and Mantovanini combined the X-ray data from eROSITA with radio data from Australian surveys to get deeper insights into high energy cosmic phenomena.

XRISM's first views signal shake-up for X-ray astronomy, Invisible to our eyes, X-rays emitted by the hot gas that fills much of the Universe can shed light on many cosmic mysteries. The 'first light' observations of this gas by JAXA’s X-Ray Imaging and Spectroscopy Mission (XRISM) are now ready. They demonstrate that the mission will play a big role in unveiling the evolution of the Universe and the structure of spacetime., : Invisible to our eyes, X-rays emitted by the hot gas that fills much of the

Today is the 11th anniversary of the European Space Agency - ESA’s Herschel Space Observatory‘s end of mission, and there is no new far-infrared mission approved to date. With SOFIA no longer operational either, we do not have access to this important wavelength regime - which cannot be observed from the ground - anymore. Last week, I had the pleasure of attending the „Heritage of SOFIA“ Heräus Seminar in Stuttgart (thanks Maja Kaźmierczak-Barthel for the fantastic organization!), and the impact that „being blind“ at far-infrared wavelengths has on so many research areas in astronomy became painfully obvious. The far-infrared regime is essential for studying the early phases of star formation, molecular cloud physics, magnetic fields, and many more. Several mission concepts like PRIMA, SALTUS, FIRSST, GREX-PLUS, and others are currently being studied, so hopefully astronomy will re-gain access to this important regime in the coming decades (and I certainly would be very happy to see a Swiss contribution, just like with Herschel, so a new generation of far-infrared astronomers can be trained in Switzerland as well). #astronomy #farinfrared (Slide shown by one the speakers at last week’s conference.)

🌟 Unlocking the Universe with Light: Scientific Missions Supported by Teledyne Digital Imaging 🌟 Electromagnetic radiation (light) serves as the primary messenger of information in the Universe. Detecting light is crucial for many scientific fields, especially those that require “remote sensing” of distant objects. The fundamentals and space missions of various scientific fields – Astronomy, Planetary Exploration, Heliophysics and Earth Observation – are topics that Teledyne will present each month in the Digital Imaging Space Science Monthly. Readers can download these articles in PDF format for non-commercial purposes, including classroom use. Let’s celebrate scientific exploration together! 🔭📚 https://ow.ly/gVM150QOGjp #ScienceEducation #STEMTeachers #AstronomyEducation #PlanetaryExploration #HeliophysicsResearch #EarthObservation #TeledyneDetectors

A very relevant source of recommendations and thoughts for the discussions on the draft EU Space Law coming out soon and for ongoing review and reform processes of national space law. Gratulations to IAU CPS for the immense works and lobbying activities over the past months. #spacelaw #spaceindustry #newspace #bholegal #iisl #escl #euspace

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
