### Episode Summary  
Real-time images of exploding stars, a surprisingly “gentle” supermassive black hole, the return of a long-duration Soyuz crew, a packed week of launches, Subaru’s first new exoplanet and brown-dwarf finds, and a controversial plan to light up the night sky with orbital mirrors.
### Timestamps & Stories  
00:00 – Cold Open  
00:35 – Intro  
01:05 – **Story 1: Astronomers watch novae explode in real time**  
**Key Facts**  
- First-ever direct imaging of two novae as they erupted using the CHARA optical interferometer  
- V1674 Herculis: fastest nova on record; brightened & faded in days; showed two perpendicular gas jets  
- V1405 Cassiopeiae: visible to naked eye for months; delayed ejection after 50+ days  
- Gamma-ray bursts from Fermi telescope timed perfectly with visible jets  
03:35 – **Story 2: Soyuz MS-27 crew lands after 8-month ISS mission**  
**Key Facts**  
- Crew of three returned safely to Kazakhstan on 8 Dec 2025  
- 260+ days in orbit (launched April 2025)  
- Handover completed; ISS now at full Expedition strength for next rotation  
05:05 – **Story 3: Launch Roundup (8–15 Dec 2025)**  
**Key Facts**  
- SpaceX Starship Flight 6 (Texas) – major reusability test  
- China Long March 7A – new Tiangong station module  
- ULA Vulcan Centaur Cert-2 (Cape Canaveral) – second certification flight  
- Rocket Lab Electron (New Zealand) – successful dawn launch  
- Russia Soyuz-2.1b (Vostochny) – classified payload  
06:35 – **Story 4: Subaru Telescope’s first discoveries**  
**Key Facts**  
- First science results from upgraded high-contrast infrared instruments  
- New brown dwarf (13–80 Jupiter masses) with dusty disk  
- New wide-orbit gas-giant exoplanet ~300 light-years away showing methane & water signatures  
08:05 – **Story 5: Sagittarius A* is less destructive than thought**  
**Key Facts**  
- Objects like G2/DSO, D9, X3, X7 all survive stable orbits within 0.8 parsecs of the 4-million-solar-mass black hole  
- 20+ years of VLT data (SINFONI, NACO, ERIS) show no tidal disruption  
- Galactic Center may be a star-formation zone rather than a shredder  
09:55 – **Story 6: Giant space mirrors to light up the night**  
**Key Facts**  
- Reflect Orbital plans thousands of mirror satellites by 2030  
- Each beam ~5 km wide, 4× brighter than full moon  
- Goal: extend solar-farm output after sunset & aid night rescues  
- Astronomers warn of catastrophic light-pollution increase and wildlife disruption  
11:20 – Outro
