"How it started/how it's going," space edition:
On March 17, 2013 a flash appeared on the Moon. It was bright enough to see with the naked eye.
Now we can see the result: a new 18-meter-wide crater, blasted out by a watermelon-size meteoroid.

Women are 14 times more likely to die in a climate disaster than men. It’s just one way climate change is gendered
Women and gender-diverse people bear the brunt of climate change’s negative affects. If Australia wants to be taken seriously on climate action, this needs addressing.The Conversation
Today, the Greenland ice sheet is melting rapidly, and some scientists worry that the Atlantic current system may be headed for a climate tipping point this century.
New research, published in the journal Science, suggests that the risk is not as imminent as some people fear, because of data gleaned from historic iceberg records.
Is collapse of the Atlantic Ocean circulation really imminent? Icebergs’ history reveals some clues
If the ocean circulation, known as AMOC, shuts down, it would be a climate disaster, particularly for Europe and North America. New research shows why that might not happen as soon as some fear.The Conversation
The "Enlightenment" of Western culture makes for a nice story, but that's really all it is — a story.

#OTD in 1919.
Albert Einstein's theory of general relativity is tested by Arthur Eddington and Andrew Claude de la Cherois Crommelin.
The Eddington experiment was organised by the astronomers Frank Watson Dyson & Arthur Stanley Eddington in 1919. The observations were of the total solar eclipse of 29 May 1919 and were carried out by two expeditions which aim was to measure the gravitational deflection of starlight passing near the Sun.

"This network stretched two stories underground and housed one billion ants"
They talk about an ancient ants' kingdom, they never said it was abandoned.
As there are no ants visible, I do hope it was abandonded. But after 10 days of relentlessly incoming cement it would have been, for sure.
I wonder why they had to dig it out... it could have meant shelter for a lot of other insects, bugs, small critters...

Gliese 12 b is an Earth-size planet orbiting in the temperate zone around a nearby, stable red dwarf star. It's a Rosetta Stone world that will tell us a lot about how many superficially earthlike planets actually have the right conditions for life.
Are we rare? Are we common? Let's find out.

Ok, Fediverse, now your support is needed:
As part of my psychology degree I'm involved in a small study about the emotional rating of images.
It's an online experiment that can be done from home or elsewhere and takes about 10 minutes. All you need is a device with a halfway modern web browser and a keyboard.
Here's the experiment:

Please also share it widely, boost, tell your friends, coworkers, relatives, etc. We're happy about every participation.
Thanks a lot. 💜

The birth of a new, sunlike star is beautiful and spooky in this new image from Hubble. (34 years old and going strong!)
The ominous "mask" is a cloud of cool dust. The baby star HP Tau, top of the trio, is flickering madly due to inspiraling gas, jets, and huge starspots.

Black hole singularities defy the laws of physics. New research presents a bold solution to this puzzle: Black holes may actually be a theoretical type of star called a 'gravastar,' filled with universe-expanding dark energy.Andrey Feldman (Live Science)
English self-taught mathematician and physicist Oliver Heaviside was born #OTD in 1850.
He invented a new technique for solving differential equations, independently developed vector calculus, and rewrote Maxwell's equations in the form commonly used today. He significantly shaped the way Maxwell's equations are understood and applied in the decades following Maxwell's death. His practical experience in telegraphy provided a foundation for his later theoretical work.

This deceptively simple-looking graph is a spectrum of *gravitational waves* ringing through the Milky Way.
