Magnificent spiral galaxy NGC 4565 is viewed edge-on from planet Earth. Also known as the Needle Galaxy for its narrow profile, bright NGC 4565 is a stop on many telescopic tours of the northern sky, in the faint but well-groomed constellation Coma Berenices. This sharp, colorful image reveals the galaxy's boxy, bulging central core cut by obscuring dust lanes that lace NGC 4565's thin galactic plane. NGC 4565 lies around 40 million light-years distant while the spiral galaxy itself spans some 100,000 light-years. That's about the size of our own Milky Way. Easily spotted with small telescopes, deep sky enthusiasts consider NGC 4565 to be a prominent celestial masterpiece Messier missed.

Yet again, USA: Require that Congress affirm that government agencies will operate and spend money as it has ordered. And #ImpeachTrump and remove him & those with them for this crime against humanity.

And, yet again, USA: Require that Congress do its job, #ImpeachRFKJr, and remove him & those with him before they kill even more people than they already have.

Time for #Minnesota, #Wisconsin, #Michigan, and #Illinois to reactivate the 2020 Midwest Regional Pact?

20 years after Katrina and this is what the governors of Louisiana & Mississippi are doing during hurricane season.

Today on the #arXiv: Salazar Manzano et al. 2025, "Onset of CN Emission in 3I/ATLAS: Evidence for Strong Carbon-Chain Depletion" arxiv.org/abs/2509.01647 Like solar system comets, #3I has a coma loaded with cyanide and laced with carbonyls. The details are interesting. And don't taste the comet.

Again: You are not actually making an argument against what is being talked about here. I am done.

A rare intersection between astronomy and @steventdennis.bsky.social 's #FridayNightZillow.

Interested in owning a part of Australian history? The Molonglo Observatory site is for sale: www.realestate.com.au/property-hou... Don't worry, we stopped scientific operations a few years ago and gave it a suitable farewell (see next post). #RadioAstronomy

Four pictures of the Molonglo Telescope site, from a Ray White real estate advert. The main top image shows the telescope infrastructure, extending out across farming land.

Eric Schmitt is so racist that he would apparently exclude my Irish ancestors who came to the United States because they were fleeing the famine. He is just as bad as JD Vance, who wants to bring back lines from the Plantation of Ulster.

The Shinkansen covers a distance equivalent to either of the United States' east and west coasts. Although not all at the speeds of the new maglev.

There is a typo in the price. But $70 billion on high-speed rail is a great investment.

That is a typo. JR Tokai has budgeted ~10 trillion yen for the project, which is near 70 billion US dollars.

Wright founded a fracking company in 1992, a few years out of MIT and Berkeley. He knows exactly what he is doing when he promotes self-serving and outrageous disinformation.

Thank you for pointing this out. And I remind myself that the blatancy of the lies in propaganda is itself one way of asserting political power.

@carnage4life.bsky.social Chris Wright has a master's in electrical engineering. He is simply blatantly lying as propaganda.

This is less chemistry and more surface physics. The helium atoms get stuck to the crystals in regolith grains - there are no reactions or gas pockets. It disassociates and diffuses out when heated up enough. (I learned this because I had the privilege of having Bob Pepin as a teacher.)
