#OTD in 1609, Galileo Galilei aimed his telescope at the Moon.
While not being the first person to observe the Moon through a telescope (English mathematician Thomas Harriot had done it four months before but only saw a "strange spottednesse"), Galileo was the first to deduce the cause of the uneven waning as light occlusion from lunar mountains and craters. In his study, he also made topographical charts, estimating the heights of the mountains. via @wikipedia
Working in tandem, NASA's Parker Solar Probe and ESA's Solar Orbiter are making big discoveries about how the Sun works.
One particularly intriguing observation: a strange plasma "snake" slithering all the way across the solar surface.

NASA's Parker Solar Probe has set a new record as the fastest object ever built, hitting a velocity of 394,736 mph (635,266 kph) relative to the Sun.
That's about 300 times as fast as a speeding bullet. Damn!

For a dose of perspective: Even at the peak speed of the Parker Solar Probe (~180 km/sec), it would take more than 7,000 years to reach Alpha Centauri, the nearest star system.
The rock gardens on Rapa Nui (Easter Island) tell the story of a small, resilient population of around 3-4,000 people even when massive sculptures were erected, according to a new study.
This counters the widely-held notion of a doomed, overpopulated island that failed to live sustainably

"Your brain isn't fully formed/you're not really an adult until age 25" is not really supported by neuroscience - and this factoid is doing harm to people. We need to drop it. https://slate.com/technology/2022/11/brain-development-25-year-old-mature-myth.html #neuroscience #science
Everyone is at the park! It’s a beautiful evening for reading.
Pioneering geologist & oceanographer Marie Tharp changed our understanding of the ocean.
When Tharp sought a geology job at Columbia in 1948, women couldn’t go on research ships. So she was hired to assist male grad students.
Back then, many scientists still assumed the bottom of the ocean was featureless. Tharp figured out how to use data to create sketches of the ocean floor. Her hand-drawn maps helped develop plate tectonic theory. https://www.ncei.noaa.gov/news/marie-tharp #science #history
I'm really enjoying the new podcast "Crash Course Pods: The Universe" by astrophysicists Katie Mack, aka @AstroKatie, and writer John Green, about, well, The Universe, from its beginnings to how it might end. Two episodes are already out, and I highly recommend them.
The “History” channel 😆
I simply adore this comic by Sketching Science #science #art
There are massive differences in the GHG emissions of different foods & "local" isn't always best for the environment.
This chart continues to be a great reference I return to in my work. Source: https://ourworldindata.org/food-choice-vs-eating-local #science #climate #food
I'm tired of sitting through #science talks where all plots are properly credited but artist's impressions and photographs aren't.
As a researcher and astrophotographer who works with super talented artists, this attitude really bothers me.
You study galaxies at the dawn of time. You look for biomarkers in the atmospheres of distant planets. You can most definitely find who made that cool image you just pasted in your slides.
To those who do credit #art : you're awesome 🤗
Earth has a lot of humans & cattle. But not too many wild animals. #science #data
Earth has more livestock than humans, wild mammals & birds combined.

I've been listening to season 6 of NASA's Curious Universe podcast. So far there are 5 episodes, all of them really good!

“Man the Hunter has dominated the study of human evolution for nearly half a century & pervaded popular culture. [But] it was the arrival of agriculture that led to rigid gendered roles & economic inequality. Hunting belonged to everyone.”
The Theory That Men Evolved to Hunt & Women Evolved to Gather Is Wrong https://www.scientificamerican.com/article/the-theory-that-men-evolved-to-hunt-and-women-evolved-to-gather-is-wrong1/ #science #history
Mary Anning was born in 1799 in Great Britain. Her family lived in poverty, selling fossils to make ends meet.
Scientists of Anning’s day could not believe that a poor young woman could posses her knowledge & talent. She has been described as 'the greatest fossilist the world ever knew' yet many people are still unaware of her incredible contributions.
The majority of Anning’s discoveries ended up in museums & collections without credit. https://ucmp.berkeley.edu/history/anning.html #science #history
