"The world is still beautiful, even with all the traffic, the injustice, the noise, the wars. The world is still beautiful. It's all we have and we should celebrate it." - Film score composer Lionel Newman
1:37:11 PM on Tuesday, July 15, 2025, over the North Atlantic Ocean.
From The Hobbit:
"The stars are in blossom, the moon is in flower,
And bright are the windows of Night in her tower."

The most likely window for start of episode 37 is between tomorrow November 26 and Thanksgiving Day, November 27. This forecast may change if additional unexpected deflation events occur. Previous episodes have been preceded by hours to days of precursory overflows of degassed magma.

New observations of Uranus’s small inner moons to be presented at #AGU25 reveal that they’re darker, redder, and more water-poor than their larger counterparts. And they’re not always where they should be. 🧪🔭🪐 eos.org/articles/ura...

Ice shell thinning on small icy satellites in the outer Solar System can cause subsurface oceans to boil, according to a study in Nature Astronomy. This process may help to explain surface features and geological activity on moons such as Saturn’s Mimas and Enceladus. go.nature.com/3JVCJ2p 🔭 🧪

This morning I was up before sunrise. It was surprisingly clear, so I took out my telescope to catch 3I/ATLAS. I let it thermalize, turned it on, and had just 1 one minute of observing it before it clouded up. Hopefully, I'll have better weather soon. It's the fuzzy spot at the center of the image.🔭

The view from from the windows of the Apollo 12 Lunar Module just after landing 56 years ago. Apollo 12 was a great mission although the loss of the color TV camera at the beginning of the first EVA was a blow to live network coverage. In due time we saw the color and B&W photos the crew returned.

In 1885, after traveling for over two million years, the light from an exploding star swept over caused astronomers to think the universe was way smaller than it really is.
