Nearly half of all stars are born in binary systems, with the most massive ones dying the fastest. It’s not pretty for the “second” star.

A history of injustice and the greatest natural location for ground-based telescopes have long been at odds. Here’s how the healing begins.

The highest-energy particles could be a sign of new, unexpected physics. But the simplest, most mundane explanation is particularly iron-ic.

Stars are born, live, and die within the spiral arms of galaxies like the Milky Way. These 19 JWST spirals deliver unprecedented riches.

A new measurement offers insights on the density of the mysterious force driving the Universe’s expansion.

The first observational evidence showing the Universe is expanding is 100 years old now: in 2023. Here’s the story of its 100th anniversary.

In July of 2022, the first science images from JWST were unveiled. Two years later, it’s changed our view of the Universe.

In 2022, Hubble owned the record for most distant galaxy. Today, that galaxy is down to the 9th most distant object. Thanks, JWST.

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.

The nearby, bright star Fomalhaut had the first optically imaged planetary candidate. Using JWST’s eyes, astronomers found so much more.

On July 12, 2022, JWST will release its first science images. Here are 5 ways the telescope’s findings could change science forever.

Temperatures in the Sun’s core exceed 10 million degrees Celsius. But how on Earth did we actually come to know that?

Along with gravitational lensing and ALMA’s incredible long-wavelength spectroscopy, JWST is reshaping our view of the early Universe.

Forget billions and billions. When it comes to the number of galaxies in the Universe, both theorists’ and observers’ estimates are too low.

How fast is the Universe expanding? Two major methods disagree. New JWST data, just released, strengthens this Hubble tension even further.

From when its light was emitted, the El Gordo galaxy cluster might be the most massive object in all of existence. Here’s how JWST sees it.

Astronomers have been looking for radio waves sent by a distant civilization for more than 60 years.

The 5th brightest star in our night sky is young, blue, and apparently devoid of massive planets. New JWST observations deepen the mystery.

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.

A deep dive into the chaotic journey of star formation.

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

Earth is actively broadcasting and actively searching for intelligent civilizations. But could our technology even detect ourselves?

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.

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

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

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.

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

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

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