Are the colours in astronomical images real? What do these colours mean? And what about images that aren't taken in visible light?

We get these questions all the time, so in the latest episode of Chasing Starlight we show you how these colourful images are made:

Lise Meitner died #OTD in 1968.

She is known for her part in the discovery of nuclear fission. Among physicists she had been known for many years as one of the early pioneers in the study of radioactivity. Einstein nicknamed her ‘the German Madame Curie’ despite being Austrian.

Africa is bigger than China, the US, Eastern Europe & India combined.

Since Earth is a sphere, flat maps dramatically distort the size of continents.

1/3 Today you're gonna hear a lot of hype about a blue #SuperMoon, so let me unpack what this means.

The Moon's orbit around the Earth is slightly elliptical. Sometimes it's a bit closer and thus looks a tad bigger. The difference is barely noticeable, not even remotely close to "super".

"Blue Moon" refers to this being the third full #Moon in a season that has four or, more commonly (but not in this case) the second full Moon in a month.

#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.

Interstellar distances are HUGE.

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

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.

There are massive differences in the GHG emissions of different foods & "local" isn't always best for the environment.

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
