The only feeling I have about starship is dread.

They want to use that to launch batches of HUNDREDS of Starlinks at once. And guess where all those Starlinks will end up? The pieces that don't make it to the ground will end up in our upper atmosphere, screwing up the stratosphere, the ozone layer, who knows what else because SpaceX isn't required to do any environmental assessments of this.

Shit. Maybe a good time to post this essay I wrote yet again: https://theconversation.com/an-astronomers-lament-satellite-megaconstellations-are-ruining-space-exploration-215653

Why the huge increase in days with #ExtremeHeat?

Climate change does two things to air temperature:
1. The AVERAGE shifts to higher temperature. This one is obvious. But also:
2. The VARIANCE gets larger so the extremes become more prevalent

Both of these effects together give a LOT more VERY hot days.

Mexico is ahead of the US with electing a woman president bc they have 50% gender quotas for party nominees. Their Congress is 50% women. They decriminalized abortion in 2023. Femicide is on the rise but it is recognized as a distinct crime.

New images of #Jupiter's volcano-studded #moon #Io, taken by the Large Binocular Telescope (#LBT), offer the highest resolution of Io ever achieved with an Earth-based instrument.

The eruptions on Io, the most volcanically active body in the solar system, dwarf their contemporaries on Earth.

Io, therefore, presents a unique opportunity to learn about the mighty eruptions that helped shape the surfaces of the Earth and the moon in their distant pasts.

Reasons why Trump's trial was clearly RIGGED:

-The jury was literate, meaning they may have been influenced by WOKE documents.

-President Trump was never offered a bed or pillow, forcing him to sleep at his hard table during the trial.

-The judge was dressed in black, an ANTIFA color.

Had a nice visit here in Tucson today with Jhong-Fu Huang from the Taiwan Dark Sky Association. He is visiting the U.S. on a National Committee on U.S.-China Relations fellowship. We talked about dark-skies efforts in our respective countries and how we can work together more closely.

The United States is currently in a Schrodinger's cat state of mostly fucked/completely fucked and a jury is about to open the box

Citizen scientists with robotic telescopes recently confirmed the existence of an exoplanet: https://arxiv.org/abs/2405.15021

When I was born, we still didn't have evidence that there were planets around other suns. Now you can observe them in your backyard. That's pretty amazing, if you ask me!

I forgot about this scene in Halt and Catch Fire. I’ll be submitting a formal complaint first thing in the morning :) #esperanto

I reprojected each image to fit the grids to a cylindrical map projection. Then I did the same reprojection with an identical but ungridded image. Fitting them together gave me this initial map.

I don’t own a car and I ride my bike a lot, often on very busy city streets. I always wear a helmet when I ride — not because it makes me less likely to get hit by a car, but because it makes me less likely to suffer from brain damage if and when I do get hit by a car.

However, as Dave Walker (@davewalker) points out, there are MANY other and much better ways to make cycling safer for everyone. 🚲
