We refer to these measurements in "parts per million", i.e. if we measure one million photons exactly one of them will have been impacted by the planet's atmosphere.

For a hypothetical earth-sized planet around a small star, a biosignature is 10 parts per million

To put into context how hard this is, measuring a biosignature in the atmosphere of this hypothetical #exoplanet is equivalent to finding a SINGLE grain of rice in a 5 lb bag.

Did you see the news that all of the #JWST instruments are aligned now?

Check out this comparison of one of the newly released calibration images from the MIRI instrument compared to images taken of the same region of space by the WISE and Spitzer space telescopes! Look at that resolution! So many newly resolved stars and structures! 🤩

I can't wait for all the new discoveries we'll make with JWST! #Science data starts in only a couple months!

Data science

I'll ask here in English and already asked at a Brazilian instance @ursalzona in Portugues, tips of alternatives to Google:
1) Which good and fast link dontou suggest as an alternative to Google Translate? Here at @climatejustice.social there's a lot of posts in German and I just know very few words, but I don't want to depend on Google;
2) Instead of Google for searching, I wear ecosia.org, which promises to plant trees for each search. Before that I wore duckduckgo. Any other suggestions?
Thanks!

How does that cockle know what way is up? We have a fluid filled inner ear to maintain balance. Most marine invertebrates use organs called statocysts. Pellets inside called statoliths sink and tell them which way is down. In clams, statoliths are made of carbonate, like their shells. Some clams have many statoliths, such as this scallop. The complexity of the statocyst often relates to how mobile the animal is. Scallops are swimmers, but other immobile clams have simpler statocysts. #clamfacts

By now you might be wondering: Why is the telescope #gold?

The mirrors are actually made of Beryllium, which is a very strong and lightweight metal, and are coated in a very thin layer of gold. The total amount of gold on #JWST is only about the size of a marble!

Why gold? Gold is VERY efficient at reflecting infrared light! JWST is designed to search for this heat in the early universe

@dantheclamman thought of you when I came across this. Interesting naming quirk!

From the article:

"Although the megalodon is the most widely known as a giant prehistoric shark, I recently learned that Megalodon wi th a capital M is more accurately the genus name of a group of exinct bivalve mollusks that lived from the Devonian to the Jurassic (picture an ordinary-looking clam)."
