It was a real privilege to speak at @TEDxMacc on the global effort needed to build the @SKA_telescope. Like many ambitious space projects, collaboration is key. Huge thanks to everyone who helped me prepare and deliver this talk! youtu.be/GxYsUWYlWHI

High resolution star trail from the SpaceX Crew 9 Dragon, marked by a fleet of flashing Starlink satellites, glowing atmosphere, soon to rise sun, and arcing stars. Captured over the Pacific Ocean with Nikon Z9, Sigma 14mm f1.4 lens, effective 24 minute exposure compiled from individual 30 second frames, f1.4, ISO 1600.

As a result of these improvements, the @starlink V2 satellites are darker than V1s despite being larger in size (both bus and solar arrays).

The @Starlink satellites minimize brightness and resulting impacts on ground-based astronomy by employing a dielectric mirror on the satellite to reflect light away from the Earth, along with off-pointing of the solar arrays and black paint on satellite components. Low altitude operations also minimizes brightness impacts.

Starlink constellations are our most frequent satellite sightings from space station, appearing as distinct and numerous orbiting streaks in my star trail exposures.

Fantastic project news from Australia a long time in the making! This is only the beginning, and the SKA-Low telescope will detect many, many more as its sensitivity increases over the coming years! 🌌

🚀 Le 2 février, SpaceX avait échoué à désorbiter le second étage de sa #Falcon9. Celui-ci est rentré dans l'atmosphère terrestre la nuit dernière vers 3h43 UTC au-dessus de l'Europe. Un débris a été retrouvé en Pologne près de Pozna. 📷Adam Borucki 1/2

Cosmic fireflies. Actually, these are Starlink satellites momentarily flashing sunlight towards @Space_Station.

Shortly after 9 p.m. EDT, @NASA instructed crews aboard the space station to shelter in their respective spacecraft as a standard precautionary measure after it was informed of a satellite break-up at an altitude near the station’s earlier Wednesday. Mission Control continued to monitor the path of the debris, and after about an hour, the crew was cleared to exit their spacecraft and the station resumed normal operations.

The satellite-strewn sky, in a stack of cumulative exposures taken over just 30 minutes on June 4/5, 2024 from latitude 51° N, looking south. The field is 100° by 75°. There's one natural streak, from a meteor, at center. The others are from what humans put there. @twanight
