The First Thing They Burn: Why War Always Comes for Beauty
When the Mongol army sacked Baghdad in 1258, they did not stop at killing the Caliph. They threw the contents of the House of Wisdom into the Tigris. Manuscripts on astronomy, medicine, mathematics, philosophy, and poetry turned the river black with ink for days. Killing people was not enough. What those people had made, what they had thought and dreamed and rendered into form, that had to be annihilated too.

And all 32 #AmazonLeo satellites have been deployed by the first #Ariane 64: good news for Arianespace and Amazon but probably bad news for astronomy as the previous satellites of this #megaconstellation have proven to be brighter than they should be. As this diagram from the recent paper "Brightness Characterization and Modeling for Amazon Leo Satellites" - arxiv.org/abs/2601.07708 - shows they are almost always brighter than the informally established 7 mag. limit. And there are no indications that the design of the 32 added to the constellation today had been modified to make them dimmer ... while the next Ariane launch will carry more of them.

Modern astronomy has a new giant among its ranks.
NASA has completed the assembly of the
Nancy Grace Roman
space telescope
in the laboratories of the Goddard Space Flight Center.
The result of an ambitious project conducted piece by piece,
this new observatory is in line with the Hubble and James Webb, while displaying distinct capabilities.

Sonnet 014 - XIV
Not from the stars do I my judgement pluck;
And yet methinks I have Astronomy,
But not to tell of good or evil luck,
Of plagues, of dearths, or seasons' quality;
Nor can I fortune to brief minutes tell,
Pointing to each his thunder, rain and wind,
Or say with princes if it shall go well
By oft predict that I in heaven find:
But from thine eyes my knowledge I derive,
And, constant stars, in them I read such art <…

Absolutely stunning moon halo tonight. The belt of Orion is visible in the lower left. The planet Jupiter, the top left. And Capella shines brightly to the right. Gorgeous! #Astronomy #tennessee #moon

Alexander Venner,
currently studying at the Max Planck Institute for Astronomy,
picked his way by hand through the data collected by a now-retired NASA space-based telescope called Kepler,
which was used to examine the sky for exoplanets during a survey of 500,000 stars that ended 8 years ago.
Datasets like these are huge, and often combed through with search algorithms,
but the PhD student managed what others did not by rolling up his sleeves, so to speak.

How to Submit Comments on Satellite Applications to the FCC
Any member of the public can provide input to the Federal Communications Commission (FCC) as it considers satellite applications.
The AAS believes that its individual members (in addition to the Society as a whole) should be able to voice concerns about any proposed satellite system that might be harmful to astronomy and the night sky.
This process is also open to those outside the United States who may be impact…

"Astronomers have made a truly mind-boggling discovery using the James Webb Space Telescope (JWST): a runaway black hole 10 million times larger than the sun, rocketing through space at a staggering 2.2 million miles per hour (1,000 kilometers per second).
That not only makes this the first confirmed runaway supermassive black hole, but this object is also one of the fastest-moving bodies ever detected..."
