Europe Launches From Europe — And Two White Dwarfs Six Minutes Apart

A German rocket lifted off from an Arctic island on Saturday and became the first vehicle ever to reach orbit from Western European soil. Plus: the gaps in stellar streams may not be dark matter after all, two white dwarfs circling every 374 seconds in the far southern sky, peptides that fold in concentrated sulfuric acid, and what Katalyst's LINK is actually doing next to Swift. Both-hemispheres skywatch, and a serious safety warning for tomorrow's daylight Jupiter occultation.Links & sources ·         Isar Aerospace — mission updates — https://isaraerospace.com/mission-updates-overview ·         ESA — Spectrum launches to orbit (imagery) — https://www.esa.int/ESA_Multimedia/Images/2026/09/Spectrum_launches_to_orbit ·         NASASpaceflight — Isar 'Onward and Upward' — https://www.nasaspaceflight.com/2026/09/isar-onward-and-upward/ ·         Space.com — Private German rocket makes history — https://www.space.com/space-exploration/launches-spacecraft/isar-aerospace-second-launch-norway-andoya-spaceport-spectrum-rocket ·         Space.com — Gilmour Space eyes a second orbital attempt — https://www.space.com/space-exploration/launches-spacecraft/australias-gilmour-space-not-going-to-give-up-as-it-eyes-2nd-orbital-launch-attempt-in-2026 ·         Sky & Telescope — Gaps in stellar streams may be common — https://skyandtelescope.org/astronomy-news/gaps-in-stellar-streams-common-not-sign-dark-matter/ ·         Arora et al. — Semianalytic modeling of subhalo encounters with thin stellar streams, ApJ — https://iopscience.iop.org/article/10.3847/1538-4357/adf740 ·         Sharma et al. — Rapid orbital decay in eRASSU J060839.5−704014 (arXiv) — https://arxiv.org/abs/2608.09341 ·         Maitra et al. — eRASSU J060839.5−704014 discovery paper, A&A (2024) — https://www.aanda.org/articles/aa/ref/2024/03/aa47811-23/aa47811-23.html ·         MIT News — Peptides can form well-defined structures in Venus-like conditions — https://news.mit.edu/2026/study-peptides-can-form-well-defined-structures-harsh-venus-conditions-0831 ·         NASA Swift blog — Commercial spacecraft for Swift boost continues tech demo — https://science.nasa.gov/blogs/swift/2026/09/04/commercial-spacecraft-for-nasas-swift-boost-continues-tech-demo/ ·         NASA Swift blog — LINK spacecraft recovery progressing — https://science.nasa.gov/blogs/swift/2026/08/06/link-spacecraft-recovery-progressing-for-nasas-swift-boost/ ·         EarthSky — Saturn at opposition, 4 October 2026 — https://earthsky.org/astronomy-essentials/saturn-at-opposition-closest-brightest-best/ ·         Star Walk — Astronomical events, September 2026 — https://starwalk.space/en/news/night-sky-tonight-septemberBecome a supporter of this podcast: https://www.spreaker.com/podcast/astronomy-daily-latest-space-news--5648921/support.Sponsor Details:Ensure your online privacy by using NordVPN.
