Cecilia Payne’s 1925 doctoral thesis was one of the most important works in the history of astrophysics. At just 25, she used spectroscopy to show that stars are made almost entirely of hydrogen and helium, an idea that overturned what every major astronomer believed at the time.

Her advisor, Henry Norris Russell, pressured her to downplay her conclusion, insisting it must be wrong because it contradicted established scientific opinion.

Four years later, Russell published a paper confirming her findings and received most of the credit, even though Payne had reached the conclusion first and with stronger evidence.

Over time, historians and scientists have corrected the record, recognizing Cecilia Payne-Gaposchkin as the person who truly discovered the chemical composition of the stars. Her thesis is now widely considered the most brilliant PhD dissertation ever written in astronomy.

Before her groundbreaking thesis, Cecilia Payne had already made a quiet but radical contribution to astronomy: she was the first person to apply quantum physics to stellar atmospheres, using newly developed atomic theory to decode how elements absorb light at different temperatures. This was cutting‑edge science in the 1920s, so new that most astronomers didn’t yet understand it, and it allowed her to interpret stellar spectra in a way no one else could. In other words, her discovery about hydrogen wasn’t a lucky insight; it was the result of her being one of the only astronomers in the world fluent in both astrophysics and quantum mechanics at a time when the two fields barely spoke to each other.

Climate change isn't some abstract bar on a graph. It’s not happening in some far off future. It's happening now, in communities across the US.

60%+ of the US is under drought. The climate crisis is fueling extreme weather. We must switch to clean energy. https://t.co/KtjDEcd8uZ

One of the most brutal scenes in human history has been leaked.

An Israeli soldier filmed and published this clip while proudly boasting about the destruction of all homes in Gaza.

A video that the world must never forget.

Weeds are resilient native plants essential for Bees and nature that the pesticide industry has successfully demonized so people are obsessed with getting rid of them and companies like Bayer can rake in a huge profit whilst Bees and birds starve and die

The most terrifying scenes in human history that I will never forget

When the Israeli soldiers opened fire on us starving people as we ran towards an aid truck, hunger was stronger than fear.

Remember when all the Supreme Court
Justices set the 'example' for #Ethics?
Sadly, no more! 😡

Raise a ✋ if you agree that anyone who
FAILS to 'tell the truth' during testimony
before Congress, should be impeached
'immediately' or RESIGN? 🙋‍♂️

@cbonneauimages Israel has become what their prophets said of Babylon:

"The violence you have done to Lebanon will overwhelm you, and your destruction of animals will terrify you. For you have shed human blood; you have destroyed lands and cities and everyone in them." - Habakkuk 2:17

[Give A Shit About Nature @giveashitnature]

Every school should have a greenhouse, a native plant garden, and fruit trees.

Kids shouldn't just memorize dates and facts.

They should grow food, watch pollinators at work, learn how soil actually works, and understand that they can actively help the environment, not just read about it.

A garden teaches patience, responsibility, biology, and stewardship in ways no textbook can.

Imagine an entire generation that grows up knowing how to care for the land instead of just consuming from it.

Seems like basic education for the world they're inheriting.

This is Qana in South Lebanon today.

An ancient village with over 3,000 years of history — where Jesus performed the miracle of turning water into wine.

Israel is wiping it off the map.

Not a peep from the “civilized world.”

Not a word from the “international community.”

China switched on the world’s largest open-sea offshore solar farm in late 2025.

2.3 million solar panels.
2,934 steel platforms.
11,736 piles driven into the ocean floor.

Generates ~1.78 TWh annually, enough to power around 2.67 million people.

Built to survive force-11 gales and sea ice while sitting nearly 8 km offshore.

Oh… and they’re farming fish underneath it too.

Solar above. Food below.
Fossil fuels increasingly looking like old industrial scaffolding from a previous civilisation.

Trump is beyond outrageous

[Mohamad Safa @mhdksafa]

This’s Cuba and there’s no electricity

The U.S is starving millions of people in Cuba. The U.S. is laying siege cruelly cut off all fuel, power is out, leaving hospitals without electricity. Dialysis patients, babies in NICU, and others will die. This’s a crime against humanity.

[Robert Reich @RBReich]

Donald Trump just stole $1.7B from us — and he's creating a slush fund to reward his political allies.

I've never seen anything like this in my 50 years in politics.

It makes Nixon look like a boy scout.

300M+ people live in forests. 1.6B depend on them to survive.
When bulldozers come, indigenous families lose homes, food, medicine, culture.
Deforestation isn’t just environmental. It’s a human rights crisis. #IndigenousRights
