How much carbon-14 is in the air around you? I was surprised to learn how little it actually is

One of my favorite things while writing an article is learning a thing I didn't know before, usually during a side quest. Premium subscribers to my newsletter can read what I learned about carbon-14!

Oh I was being rhetorical; quite a few did! But compared to the number that just dragged on... whihc, honestly, is likely small compared to the number that were cut off early.

It feels cheap to me, like a money grab. I really like the Marvel movies, but this isn't a good look.

This is literally the best news I've heard this year. The world is a little bit better now, or at least not quite as sucky.

Rubin bags 11,000 new asteroids! This is just the beginning, too. There are more millions more out there waiting to be seen.

The Vera Rubin observatory has already discovered 11,000 *previously unknown* asteroids... and the proper observing sessions haven't even begun yet!

A new picture of NGC 3147 from Hubble, comprised of data collected very recently, some of which was taken just a couple of weeks ago. This is in near-infrared and visible light, so the dust lanes look extra reddish. There's a certain transparency to the disk showing reddish background galaxies that I quite like, thanks to the near-infrared wavelengths in the red channel. It's one of those galaxies that fits nicely within the Hubble footprint, so this is a nearly complete picture of the brighter parts of the whole object.

I enhanced the saturation and clarity of the whole galaxy, and the center dust lanes have been greatly sharpened. The small hole left where the chip gaps intersected near the nucleus was filled with data cloned 180° from the other side of the nucleus.

This image was creating using data from the Proposal That Just Keeps Giving.
The Hubble Constant to 1%: Physics beyond LambdaCDM

Red: WFC3/IR F160W
Green: WFC3/UVIS F814W
Blue: WFC3/UVIS F555W

North is NOT up. It is 42.64° clockwise from up.
