Maybe 100% of stars don’t have planets, after all. When stars form in the Universe, they’re created in giant bursts. A stellar nursery in the Large Magellanic Cloud, a satellite galaxy […]
Amid such suffering, people need some joy.
Penguin poop and climate change are fuelling the spread of ‘snow algae’ down the Antarctic Peninsula
I’m not saying it’s not aliens, but it’s not aliens. When it comes to life in the Universe, we still have no definitive answer to the biggest question of all, “are […]
It’s been spectacularly confirmed by observation, but theoretically, it couldn’t have been any other way. If the Sun were to spontaneously cease emitting light, we wouldn’t know about it for about […]
It would be the ultimate method for solving our pollution or hazardous/radioactive waste problems, but we’ll never do it. Here’s why. Imagine our planet as it was for the first 4.55 […]
Astronomers find these five chapters to be a handy way of conceiving the universe’s incredibly long lifespan.
A tourist generally has an eye for the things that have become almost invisible to the resident.
How can we save humanity from ourselves? In this life and this Universe, there will always be questions beyond the capabilities of humanity to answer. There’s so much that we’ve […]
If there’s no phosphine, there’s no indirect evidence for biological activity there. In one of the biggest surprises in the history of planetary science, a September 2020 study announced the presence […]
A man’s skeleton, found facedown with his hands bound, was unearthed near an ancient ceremonial circle during a high speed rail excavation project.
A generation ago, NASA launched their great observatories to explore the Universe. It’s time for round 2. Throughout the history of astronomy, every advance we’ve ever made has come about because […]
Your health and the health of the planet are not indistinguishable.
If it wasn’t a singularity, how small could it have been? Today, when you look out in any direction as far as the laws of physics allow us to see, the […]
The full Moon is always a sight worth looking at. This March, the full Worm Moon is a little more “super” than usual. The full Moon is always a spectacular sight: […]
From cryonics to time travel, here are some of the (highly speculative) methods that might someday be used to bring people back to life.
Theoretically, we know what happened on the red planet. Here’s how we’ll find out whether we’re right. When it comes to the worlds beyond Earth in our Solar System, it’s only […]
If you think life on Earth is hard, wait until you see Mars. If you think life on Earth is hard, try living on Mars. Mars, as photographed from the surface […]
Demanding appropriate levels of skepticism and scrutiny isn’t cruelty, but rather demonstrates scientific integrity and intellectual honesty. Every few months, a novel headline will fly across the world, claiming to […]
Scientists recently discovered a black hole that’s smaller than previously thought possible.
We know a lot about what else is out there, but we still don’t know everything. In the quest for life in the Universe, it makes sense to look at […]
Both views are equally spectacular, but unequally informative. Every so often, a creative amateur project highlights our professional achievements. This mosaic shows the region between the constellations of Cygnus and […]
Turning salt water into fresh water with the power of the sun.
In 2006, the IAU demoted Pluto. Here’s what we know today. In 2006, the last planet in our Solar System suffered an unforgettable insult, as Pluto — known for generations as our ninth […]
These needles in the vast galactic haystack take more effort to find, but they help piece together our origins.

A theoretical view of a distant world so far from our Sun that our Solar System appears barely brighter than the remaining stars in the sky. ( Caltech/R. Hurt (IPAC)) Pluto […]
Although everyone knows that coal-based energy is a thing of the past, declarations about nuclear power plants somehow do not want to enter into force.
Despite the claims of one of Earth’s newest Nobel Laureates, the data doesn’t lie. One of the greatest scientific successes of the past century was the theory of the hot Big […]
In reality, it has no color at all. Here’s why. Every time you see an illustration of the COVID-19 coronavirus, it’s shown with a red color to it. Sometimes it’s red […]
