The Twin Jet nebula, shown here, is a stunning example of a bipolar preplanetary nebula. At the center, a dying star is in the final stages of life where it […]

Despite the recent headlines, it’s an extraordinarily unlikely proposition. Have you ever wondered, if it were possible to travel through space straight ahead as quickly as you could imagine, if […]
Entropy always increases, but that doesn’t mean it was zero to start with. One of the most inviolable laws in the Universe is the second law of thermodynamics: that in any […]
Nagomi helps us find balance in discord by unifying the elements of life while staying true to ourselves.
We once thought the Moon was completely airless, but it turns out it has an atmosphere, after all. Even wilder: It has a tail of its own.
A new survey, the DESI Legacy Imaging Survey, has found more lenses than all others put together. One of Einstein’s most revolutionary predictions is that mass bends light. During a […]
Three decades after the demise of the GDR, its familiar contours keep coming back from the dead.
We may be different in many ways, but the cosmic story is the same for each of us. In all the Universe, you won’t find another planet identical to Earth. Planet […]
It comes from a supernova seen just 33 years ago, and it doesn’t pulse. 33 years ago, a supernova occurred just 168,000 light-years from Earth. This new image of the supernova […]
It peaks the nights of August 11–13, but it’s no longer the year’s most reliable meteor shower. Every year, beginning in mid-July, planet Earth commences passing through an enormous debris […]
The laws of physics aren’t changing. The Earth is. When it comes to any physical science, we know that the fundamental rules governing how the Universe works remain constant with time. […]
The ‘final parsec problem’ is still a mystery for astronomers. When it comes to black holes in the Universe, we know there are at least two major types. There are […]
The definitive answer requires better, unbiased data. Despite all the advances that have occurred in human history, one extraordinary puzzle still remains right in our own backyard: we aren’t sure how […]
The laws of physics state that you can't create or destroy matter without also creating or destroying an equal amount of antimatter. So how are we here?
The Big Bang is our accepted origin of the Universe. But is there another possibility? Since the mid-1960s and the discovery of the Cosmic Microwave Background, the Big Bang has […]
We have two ways of measuring the expansion rate. Here’s the harder one. If you want to understand where our Universe came from and where it’s going, you need to measure […]
Animals are adapting all the time these days to stay out of our way.
Why power generated through nuclear fusion will be the future, but not the present, solution to humanity's energy needs.
In order, they go: hydrogen, helium, oxygen, carbon, neon, nitrogen, magnesium, silicon, iron, sulfur. Here’s how we made them. Everything found on planet Earth is composed of the same ingredients: atoms. […]
Once only dark energy remains, empty space still won’t be completely empty. Imagine, if you dare, the very end of the Universe. The stars — past, present, and future — have all burned out. […]
The inevitable long, slow decline is accelerating, and there’s nothing we can do. The Universe, as it is today, is less active, is forming fewer stars, and is creating fewer chances […]
It’s one way to interpret recent X-ray data, but it conflicts with much, much better data we already have. Earlier this month, a new study came out claiming something shocking: perhaps […]
There are two fundamentally different ways of measuring the Universe's expansion. They disagree. "Early dark energy" might save us.
The Universe is dark, but the distorted light reveals its presence. When we look at the objects in the Universe, the mass just doesn’t add up. A galaxy that was […]
When two black holes that shouldn’t exist are seen merging, physics has some explaining to do. After years of searching for gravitational waves, it finally happened: LIGO bagged the biggest one […]
We used to think the Big Bang meant the universe began from a singularity. Nearly 100 years later, we're not so sure.
If dark matter is fundamentally different from the normal matter we know, there should be a way to test it. Here are the results. Dark matter — despite the enormous indirect evidence for […]
In 2011, a bizarre, green object was discovered. At long last, we finally understand why. One of astronomy’s biggest surprises came in 2007, when a mysterious green object was found. […]
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 […]
