  • It still is a blurry orange ball, where the orange is the location of radio wave emission. The team did a new image where they measured the polarization of the light, which is the result of strong magnetic fields where the light was emitted. The lines are drawn over the image to depict the polarization orientation of the light as a function of location.

    I want to be clear that this is an incredible feat, both the fact that they can produce an image of a black hole from the center of our galaxy AND determine the polarization of the light. But they don’t have a super crisp image of matter swirling into a black hole.








  • Idk how a 10 minute drive is a half hour walk. Average walking speed is 3 mph, so a half hour is 1.5 miles. If you’re driving that in 10 minutes, you’re only averaging 9 mph.

    I don’t mean to pile on here because I understand your frustration. I grew up in NYC where basically no one drives, and didn’t get a driver’s license until my 30s when I moved to California for work. Even then I put off getting a car for years, since I like walking and don’t mind “decent” public transit.

    But it just became impossible to continue. My commute was an hour and 45 minutes (one way), with about 40 minutes of walking, a train and a bus. I like walking but when it was over 100 degrees in the summer, or raining, or a wildfire smoke day it was miserable. The buses run every 30 minutes so if there’s a missed connection the commute becomes over 2 hours (still just one way). And the train has only 1 line so when there’s a mechanical issue you’re out of luck and just have to call an Uber anyway.

    I finally broke down and got a car. My commute is now 30 minutes each way. The gas for my commute is somehow cheaper than the public transit. It’s ridiculous and it shouldn’t be this way, but it is.
