If you can identify a foreground star, the spike patterns are a dead giveaway as to whether it’s a JWST image or any other observatory.

In the expanding Universe, different ways of measuring its rate give incompatible answers. Nobel Laureate Adam Riess explains what it means.

In 1924, Edwin Hubble found proof that the Milky Way isn’t the only galaxy in the Universe.

A true scientific view of if, where, and when extraterrestrial life exists is within our grasp thanks to biosignatures and technosignatures.

Archaeologists can learn how societies lived by studying what they left behind when they died. Astronomers are doing much the same thing.

Hubble revolutionized astronomy more than once. Here’s what we can expect from the James Webb Space Telescope.

2022 was another busy year in the realm of science, with groundbreaking stories spanning space, materials, medicine, and technology.

2023 will see the launch of new rockets, the return of OSIRIS-REx, and a mission to Jupiter that could help us find extraterrestrial life.

One of the most promising dark matter candidates is light particles, like axions. With JWST, we can rule out many of those options already.

From inside our Solar System, zodiacal light prevents us from seeing true darkness. From billions of miles away, New Horizons finally can.

Scientists can make substantial progress without fully understanding exactly what they’re doing.

The structure of our Solar System has been known for centuries. When we finally started finding exoplanets, they surprised everyone.

When we see pictures from Hubble or JWST, they show the Universe in a series of brilliant colors. But what do those colors really tell us?

Astronomy’s roots rest in the very origins of humanity. We have always looked to the skies for answers. We are starting to get them.

With JWST, Chandra, and gravitational lensing combined, evidence has emerged for the earliest black hole ever. And wow, is it a surprise!

DESI has allowed astronomers to create an unprecedented 3D map of the Universe representing 20% of the entire sky.

With a finite 13.8 billion years having passed since the Big Bang, there’s an edge to what we can see: the cosmic horizon. What’s it like?

Unexpected images of galaxies from the James Webb Space Telescope do not disprove the Big Bang. There are other likelier explanations.

There’s no upper limit to how massive galaxies or black holes can be, but the most massive known star is only ~260 solar masses. Here’s why.

Since dark matter eludes detection, the mission will target sources of light that are sensitive to it.

Carl Sagan was far from the first to declare we are the children of ancient stars.

The closest known star that will soon undergo a core-collapse supernova is Betelgeuse, just 640 light-years away. Here’s what we’ll observe.

It was barely a century ago that we thought the Milky Way encompassed the entirety of the Universe. Now? We’re not even a special galaxy.

Figuring out the answer involved a prism, a pail of water, and a 50 year effort by the most famous father-son astronomer duo ever.

Einstein’s relativity teaches us that time isn’t absolute, but passes relatively for everyone. So how do telescopes see back through time?

If there are human-sized creatures walking around on other planets, would we be able to view them directly?

“I hope we take a mindset where we are willing to look for weird life in weird places.”

The first set of James Webb’s images blew us all away. In just 2 mere months, it’s seen highlights that no one could have predicted.

The James Webb Space Telescope viewed Neptune, our Solar System’s final planet, for the first time. Here’s what we saw, and what it means.

With a telescope at just the right distance from the Sun, we could use its gravity to enhance and magnify a potentially inhabited planet.
