Until the Apollo missions, we had no idea how the moon got here, just a series of educated guesses. They rewrote the story of the moon’s origins.
Kmele talked with a planetary scientist, a physicist, and a futurist, to understand how visionaries across disciplines are thinking about the future of our planet and humankind.

Although early Earth was a molten hellscape, once it cooled, life arose almost immediately. That original chain of life remains unbroken.
In our Solar System, even the two brightest planets frequently align in our skies. But only rarely is it spectacularly visible from Earth.
JWST just found its first transiting exoplanet, and it’s 99% the size of Earth. But with no atmosphere seen, perhaps air is truly rare.
Although mammals may be the dominant form of life today, we’re relative newcomers on planet Earth. Here’s our place in natural history.
The nearby, bright star Fomalhaut had the first optically imaged planetary candidate. Using JWST’s eyes, astronomers found so much more.
Red dwarf stars were supposed to be inhospitable. But TOI-700, now with at least two potentially habitable worlds, is quite the exception.
Some fascinating observations of K2-18b have come along with horrendous, speculative communications. There’s no evidence for oceans or life.
Total eclipses are a product of a strange and almost eerie cosmic coincidence — one that makes Earth an even rarer world in the galaxy and, by proxy, in the Universe.
Pluto failed to meet the definition of a planet, but some astronomers think there might be a legitimate Planet 9 out there.
Ocean fertilization is extremely controversial, but if done correctly, it just might work.
Does humanity have a moral imperative to seed life on lifeless worlds? And should we avoid colonizing a planet if life already exists there?
Two scientists recently wagered a bottle of whiskey. The bet? Whether we’ll find evidence of advanced extraterrestrial life in the next 15 years.
Scientists are notoriously resistant to new ideas. Are they falling prey to groupthink? Or are our current theories just that successful?
Should we be searching for life on other planets, or technology?
Why do so many cultures celebrate holidays at the same time of year?

A deep dive into the chaotic journey of star formation.
Finding this missing piece of water’s path through the universe offers clues to how it came to be on Earth.
The classic picture of Jupiter’s great rocky core might be entirely wrong.
The Universe, although violent, is filled with creation events following destructive ones. 1850 light-years away, both types are unfolding.
Freethink’s weekly countdown of the biggest space news, featuring a stranded space factory, Jeff Bezos’ new moon lander, and more.
Although human beings arrived on Earth just ~300,000 years ago, we’ve transformed the entire planet completely. Here’s how we did it.
Beyond the planets, stars, and Milky Way lie ultra-distant objects: galaxies and quasars. Here’s how far back we’ve seen throughout history.
For thousands of years, humanity had no idea how far away the stars were. In the 1600s, Newton, Huygens, and Hooke all claimed to get there.
Researchers estimate there may be as many as ten million trillion trillion phages on Earth — that’s 10 with 30 zeros after it.
By looking down, scientists are looking back in time.
The odds are slim, but the consequences would be literally world-ending. There really is a chance of a black hole devouring the Earth.
65 million years ago, a massive asteroid struck Earth. Not only did Jupiter not stop it, but it probably caused the impact itself.
