I was happy last night, I managed to guide for the first time with the big gun... For a whole 20 minutes before the clouds came in 🥹
The full scope of Paranal’s beauty 🤩
Right in front, one of the movable ATs stands tall, while the UTs are scanning the sky.
The lasers emerging from the UTs create each a bright artificial star on the sky to correct observations for the blurring effect of the atmosphere. Until recently, only one UT was equipped with lasers. But now one additional laser has been installed in the other 3.

A beautiful panorama of cosmic life & death:
These images of the Sculptor Galaxy combine 100 exposures in thousands of colors, 300 gigs of data in total. They show 500 planetary nebulae (the demise of other Suns) + a central "chimney" caused by a burst of newly formed stars.

Just got notified from the American Astronomical Society that their survey on anticipated impacts of Reflect Orbital (whose business model is "we will beam sunlight down to Earth at night because woo space”; never mind the titanic impacts on circadian rhythms of every living thing on the planet) has really gained traction.
DarkSky International has an open letter you can sign, and we expect a public comment period from the FCC on this in the next few weeks. Hit up public.policy@aas.org if you have questions. #space #astronomy
(and shout out @sundogplanets for raising the profile of this issue before I heard about it anywhere else)

A Massive Asteroid Might Slam Into the Moon in 2032. That’s Actually Pretty Exciting

Yet another processing of the same data from last Christmas, with a dedicated lucky-imaging software this time (Autostakkert, on Linux with Wine). Yeah it gets more details than my naive try :)
