"If we're related to every living thing on the planet, do we not have a special responsibility for every living thing on this planet? They are really all our relatives."
An artist's impression of a cluster of stars.
If the Universe is 13.8 billion years old today, but different ages the farther we look back, what does it mean for a star to be the first?
A man in glasses and a suit jacket, resembling John Green, stands in front of a light background with a purple rectangle and abstract black lines.
John Green opens up about his struggle to remain hopeful while writing about suffering and injustice.

“When you think about this interconnection of all these tiny causes and effects which add up to the way the world unfolds, it becomes impossible to imagine that we have complete control.”
A split image shows a star field on the left and a COSMOS-Web survey area diagram on the right, with labeled NIRCam and MIRI footprints alongside the moon for scale, highlighting galaxies explored by JWST science.
The COSMOS-Web has just finalized their release of their full field: larger and deeper than any other JWST program. Here's what's inside.
A large circular particle accelerator laboratory with various machines, cables, and equipment; two people are working near the center on experiments related to the muon g-2 anomaly.
When theory and experiment disagree, it could mean new physics. This time, they solved the muon g-2 puzzle, and saved the Standard Model.
Interior view of a large observatory telescope in operation at night, with orange light trails and a starry sky visible through the open roof.
The Vera C. Rubin Observatory in Chile will image the southern sky using the largest digital camera ever built.
Book cover with a gray textured background, featuring the title "DE KAI RAISING AI" and the subtitle "An essential guide to raising AI and parenting our future," all in white capital letters.
In "Raising AI," De Kai argues that today's AIs are already more like us than we think they are.
Edwin Hubble and Andromeda galaxy
For decades, astronomers have claimed the Milky Way will merge with Andromeda in ~4 billion years. Here's why, in 2025, that seems unlikely.

As US science faces record cuts to funding, jobs, and facilities, these 10 quotes help remind us how science brings value to us all.

“It's a remarkable series of events that were required for us to be here, and that so many things could have happened in a different way that we wouldn't be here at all, both individually, and as a species.”
A digital 3D visualization shows translucent blue shapes in front of a blue wall and floor, illustrating an abstract concept—perhaps a universe without dark matter.
In our Universe, dark matter outmasses normal matter by a 5-to-1 ratio, shaping the Universe as we know it. What if it simply weren't there?
A collage with "The Nightcrawler" text, historic photos of Indigenous people, a blue-toned statue reminiscent of Leonardo da Vinci's art, and blue ocean waves overlapping the images.
Welcome to The Nightcrawler — a weekly newsletter from Eric Markowitz covering tech, innovation, and long-term thinking.
It rotates on its axis, revolves around the Sun, moves throughout the Milky Way, and gets carried by our galaxy all throughout space.
Close-up of a large, metallic, circular structure with concentric rings and radial lines, illuminated by natural light from one side—evoking experiments that revealed the neutrino mass is smaller than once believed.
The long-elusive neutrino was shown to have a bizarre property no one expected: mass. New, tightest-ever limits have profound implications.
A split image features a sketched portrait of a bearded man above, with rippling water merging into Leonardo Da Vinci-style sketches below.
What made Leonardo da Vinci last wasn’t magic — it was process — and his study of fluids can help us win the long game.

Many were hoping that JWST would find the first stars of all. Despite many hopeful claims, it hasn't, and probably can't. Here's how we can.
A man and a woman in ancient attire sit at a table indoors, engaged in conversation; beside the jug, roses, and scroll lies a small straw man figure.

Here in our Universe, time passes at a fixed rate for all observers: one second-per-second. Before the Big Bang, things were very different.

“We are beginning to take our first steps out into the cosmic ocean… and the water seems inviting.”
A frayed rope descends from above and is attached to the top of a blue Earth, symbolizing fragility or tension.
A paradigm should be elastic enough to accommodate new data and broad enough to explain the world. For Rupert Sheldrake, ours does neither.
Large crowd of well-dressed people socializing at an indoor event; "Substack" is projected on a wall above.
The platform is a digital Royal Society for today's greatest minds — and it could play an essential role in shaping the next civilization.
A colored pixelated grid with rectangular outlines; a legend in the top right labels blue as F115W, green as F200W, and red as F277W—capturing data from the JWST to record a distant galaxy.
Coming from just 280 million years after the Big Bang, or 98% of cosmic history ago, this new, massive galaxy is a puzzle, but not a mirage.
entanglement across space
If all massive objects emit Hawking radiation, not just black holes alone, then everything is unstable, even the Universe. Can that be true?
A man with short dark hair, glasses, and a goatee, wearing a blue jacket over a light shirt, stands in front of a beige, textured background.
The "Doctor Strange" director says mystery shifts your worldview — "not in a metaphorical sense, but in a deeply experiential one."
Two bright, irregularly shaped nebula clouds with blue, purple, and pink gases dominate the dark space background, where dazzling stars twinkle—reminding us that in space, appearances can deceive.
There's an old saying that "what you see is what you get." When it comes to the Universe, however, there's often more to the full story.

“We don't have enough knowledge to precisely calculate what is going to happen, and so we assign probabilities to it, which reflects our ignorance of the situation.”
