An image of a rock in thin section, displaying crystals of various minerals (kyanite, sillimanite, muscovite, chlorite, plagioclase). A schistose texture is observed, with the muscovite being aligned and appearing to 'flow' from top right to bottom left of the image.

A nice schist with muscovite, kyanite/sillimanite, chlorite, and twinned plagioclase.

***FOLLOW LINK FOR FULL IMAGE***
"This image, captured with the NASA/ESA Hubble Space Telescope, is the largest and sharpest image ever taken of the Andromeda galaxy β€” otherwise known as M31.

This is a cropped version of the full image and has 1.5 billion pixels. You would need more than 600 HD television screens to display the whole image.

It is the biggest Hubble image ever released and shows over 100 million stars and thousands of star clusters embedded in a section of the galaxy’s pancake-shaped disc stretching across over 40 000 light-years."

Do yourself a favor: take a moment to explore the linked 1.5 BILLION pixel image (4.3 GB file) of the Andromeda galaxy, which showcases >100 million stars. And to think its just part of a single galaxy out of 200,000,000,000+ galaxies in the universe.

Vera Rubin has been selected to be featured on the back of a quarter. She is the first astronomer to be honored this way. Read about her research on the Andromeda galaxy and how it led to the discovery of dark matter in this article written by Rubin herself. doi.org/10.1063/1.24...

Migraine is more than a headache β€” a radical rethink offers hope to one billion people Drugs that can prevent or relieve migraine attacks are only effective for some people. Research is starting to untangle the reasons why.

Justice Dept. releases Trump special counsel report on Jan. 6 case President-elect Donald Trump had tried to prevent the release of special counsel Jack Smith’s report before taking office next week.

If Donald Trump hadn’t won the presidential election in November, the Justice Department would have had ample evidence to convict him at trial of trying to obstruct the 2020 election results, special counsel Jack Smith said in a report released Tuesday.

Yup, it's that time of the year again, when reporters need to find a scientist to give them a quote for their article. To save time, I've come up with this.

Rock sample of a fold, sectioned perpendicular to the fold axis, then ground and polished. It is held in a geologist's left hand. The rock consists of brown and white layers between 1mm and 1cm thick.
