Even though they're bigger, Generation 2 Starlinks are fainter than Gen1

We've filed plenty of reports here at UT warning about the potential impact of Starlink and similar satellites on the field of astronomy. We've gone so far as to point out that the granddaddy of space-based telescopes—Hubble—has already had some of its images tarnished by passing Starlink satellites.
However, SpaceX has been aware of the problem and is working to limit their product's brightness. The recently launched Gen2 satellites seem to have made a significant step forward—research from a team of amateur astronomers finds that the new Gen2 Starlinks are more than 10x fainter than previous Gen1 iterations.
Admittedly, that finding comes with a lot of caveats. But the pedigree of the team doing the research isn't in question. It was led by Anthony Mallama, a senior engineer at Raytheon and an author of numerous technical papers and articles discussing Starlink's brightness. He and six other amateur astronomers collected their own data for this paper, recently released on the arXiv pre-print server.

An international team of researchers has used NASA's James Webb Space Telescope to calculate the amount of heat energy coming from the rocky exoplanet TRAPPIST-1 c. The result suggests that the planet's atmosphere - if it exists at all - is extremely thin.
With a dayside temperature of roughly 380 kelvins (about 225 degrees Fahrenheit), TRAPPIST-1 c is now Mitsubishi Electric demonstrates light source module for high-capacity laser links

Mitsubishi Electric Corporation has successfully demonstrated laser optical frequency control using a new light source module, a key component of an envisioned high-capacity laser optical communication network to be deployed in outer space.
The module, which produces a 1.5-um wavelength signal, was installed in the OPTIMAL-1 nanosatellite developed through an industry-academia collaboratio Telstra and OneWeb seal deal on delivering new satellite solutions

Using the James Webb Space Telescope, an MPIA-led group of astronomers searched for an atmosphere on rocky exoplanet TRAPPIST-1 c. Although the planet is nearly identical in size and temperature to Venus, its atmosphere has turned out to be very different. By analysing the heat emitted from the planet, they conclude it may only have a tenuous atmosphere with minimal carbon dioxide.
