By mastering the complex physics of orbital flight, Eileen Collins became the first woman to pilot a NASA space shuttle on mission STS-63, proving that precision, training, and courage are as vital to space exploration as rocket fuel.

Would you go to space if you could? 🚀

I’ve gotta chew on this one for a bit.

Thanks for sharing, Luna!

For a long time, the Late Ordovician extinction, about 513 million years ago, seemed simple. The planet cooled, ice sheets grew, sea levels fell, and shallow seas disappeared. That explanation works… The Ordovician Extinction Had a Plot Twist #paleontology #extinction #fossils

If cooling caused the Late Ordovician extinction, the crash should have been smooth.

It wasn’t.

Something else broke the system.

How Early Animal Life Survived an Unstable Climate Why didn’t complex ecosystems vanish after Earth’s first mass extinction?

For a long time, the Cambrian explosion sounded like a clean success story.

Life appears. Complexity rises. End of story.

But around 513 million years ago, Earth’s first mass extinction quietly disrupted that narrative.

What Earth’s Deep Past Teaches Us About Climate Balance How carbon moved through Earth’s interior, oceans, and atmosphere over 540 million years

What if Earth’s climate wasn’t controlled by one dominant process…
but by a balance we’ve been underestimating for a long time?

Indeed, quite spooky!

Quote over a blurred illustration of early marine life. Text reads: “When we study deep time carefully, we learn that progress is rarely smooth. It is shaped by loss, recovery, and opportunity… It gives us a better framework for asking the right questions as we face these same events yet once again.” Attribution below: Silvia Pineda-Muñoz, PhD. Title: Some Survived. Others Didn’t. Early Vertebrates After a 445-Million-Year-Old Extinction.

Deep time doesn’t give us comfort stories.
It shows how life moves forward through loss, recovery, and narrow windows of opportunity.

Some survived. Others didn’t.
And that difference still matters today.

There’s a strange gap in our evolutionary story. DNA suggests jawed vertebrates should have existed 445 million years ago, but the rocks from that time are almost silent. For decades, this was blamed… Where did all the fish go 445 million years ago #paleontology #evolution

There’s a strange silence in our evolutionary history.
DNA says our ancestors should be there.
The rocks say otherwise.
What happened 445 million years ago?

Illustration of a child holding a smiling sun like a balloon while standing next to a melting snowman wearing a vest labeled “ICE.” Handwritten text reads, “Our humanity melts your ice,” with a small heart above the sun.

What 500 Years of Tree Rings Reveal About Climate Change in the Mediterranean Why Mediterranean weather feels more unstable, and how long-lived trees help explain it

Has Mediterranean weather always been this unstable?

Tree rings going back 500 years offer a rare long view on climate change and rainfall extremes.

The past turns out to be very instructive.

Was the First Climate Mass Extinction Really Caused by Cooling? A closer look at the Late Ordovician reveals a more complicated chain of events

We thought the first climate mass extinction was simple: an ice age wiped life out.

Then we noticed something that doesn’t fit: it happened in two pulses.

So what delivered those two blows?

Some Survived. Others Didn’t. Early Vertebrates After a 445-Million-Year-Old Extinction How extinction reorganized the early history of vertebrates

Evolution doesn’t always move forward. Sometimes it stops, resets, and rebuilds.

A 445-million-year-old extinction changed the course of vertebrate life, and we’re only now seeing how.

Everyone knows the "Hobbit" of Flores, but do you know why they really disappeared? 🕵️‍♀️ For years, we assumed modern humans were the culprits behind the extinction of Homo floresiensis. But the… Climate Collapse Ended One of Earth's Strangest Species #paleoclimate #history

Human evolution felt simple… until Flores.
What ended the Hobbit wasn’t size, or humans, or catastrophe.
It was something quieter.

Global climate change and terrestrial ecosystems. (a) Changes in global atmospheric CO2 from 1980 to 2100 under different Shared Socioeconomic Pathways-Representative Concentration Pathways (SSP-RCP) scenarios. (b) Changes in global air temperature from 1980 to 2100 under different SSP-RCP scenarios. (c) Changes in global land precipitation from 1980 to 2100 under different SSP-RCP scenarios. (d) Effects of different climate change factors on the nitrogen cycle in global terrestrial ecosystems. Yellow arrows denote interactions between systems; Red arrows indicate the impacts of climate change on terrestrial ecosystems. N, nitrogen. The symbols are from Integration and Application Network (https://ian.umces.edu/media-library/).

Climate change isn't just a story of the carbon cycle, other elemental budgets are also affected and interact. The nitrogen cycle is also affected by elevated CO2 concentrations, warming, and altered precipitation regimes. 🧪
