1 and 2. Sections of the Virgo Cluster, a group of galaxies 55 million light-years away.
3. Section of the Trifid and Lagoon nebula, 4,100 light years away.

in reply to AkaSci 🛰️ • • •Images are transferred from the Rubin Observatory using "direct writes via the S3 API to an object store" at the US Data Facility at SLAC in CA and distributed to the UK and France sites.
Given the high bandwidth-delay product of the links between sites (~8 Gbps per image transfer * ~165 ms round trip time RTT = ~165 MB), transfers are done using specialized connection pooling/keep-alive code and TCP tuning (e.g., initial and max cwnd size, congestion control, ..).

in reply to AkaSci 🛰️ • • •Check out this video depicting 2,104 never-before-seen asteroids discovered by the Rubin Observatory in about 10 hours of observations.
Seven of them are near-Earth asteroids, which fortunately pose no danger to Earth.
"Annually, about 20,000 asteroids are discovered in total by all other ground and space-based observatories. Rubin Observatory alone will discover millions of new asteroids within the first two years of the Legacy Survey of Space and Time."

PS. If you’re in touch with them, they might want to know: it looks like their web site is down: rubinobservatory.org/
