M78 is a reflection nebula located about 1350 ly away in the constellation of Orion.
We see reflection nebulae because the light from a nearby star is bouncing off the gas and dust of the nebula. #astronomy

The Milky Way is a glowing band seen across the sky. This band is made up of untold millions of stars in our own Galaxy. Since our Galaxy is a spiral or disk galaxy and we live in the disk we see it as a band across the sky. #astronomy

M104 is a spiral galaxy located about 9.5 Mly away in the constellation of Virgo.
M104 is known for its prominent dust lane, visible across the galaxy image. We can see this as the galaxy is nearly edge-on to our view. #astronomy

IC 1747 (blue dot in the line of stars at centre) is a planetary nebula located about 9800 ly away in the constellation of Cassiopeia.
IC stands for Index Catalog, a supplemental catalog to the NGC catalogue, released about 15 years after the NGC. 1747 is the PN's number in the catalog. #astronomy

What could possibly go wrong with AI designing and operating nuclear power plants…
I actually don’t want this
Tech companies are betting big on nuclear energy to meet AIs massive power demands and they're using that AI to speed up the construction of new nuclear power plants.

NGC 4647 (smaller of the two galaxies at centre) is a spiral galaxy located about 57 Mly away in the constellation of Virgo.
It seems to be starting to interact with M60 (larger of the two) which is only about 600 kly away from it. #astronomy

NGC 3384 (galaxy at top of triangle of galaxies) is an elliptical galaxy located about 35 Mly away in the constellation of Leo.
As with most elliptical galaxies, NGC 3384 is made up of mostly older Population II stars. These stars are cool red stars that have very long lives. #astronomy

They shall grow not old,
as we that are left grow old:
Age shall not weary them,
nor the years condemn.
At the going down of the sun
And in the morning
We shall remember them.

Saturn is the 6th planet in our solar system, famed for it's spectacular ring system.
As the rings are inclined to the plane of Saturn's orbit, we see them at different angles through the years. Here we see the change from 2019 (L) to 2025 (R). #astronomy

M41 is an open cluster located about 2400 ly away in the constellation of Canis Major.
Open clusters are great natural laboratories for stellar evolution. Since the stars were formed roughly at the same time, we can see how different stars evolve over time. #astronomy

Scientists say the return to "standard time" is good for our health. But the time change can be disruptive and we must also adjust to more winter darkness. Syncing our habits to our body clock helps.

You’re getting a provincial police force that nobody wanted!
Sure, it costs millions more to set up and operate, but we don’t care about fiscal responsibility. The UCP needs a police force we can control and answers to us!
