There are billions of potentially inhabited planets in the Milky Way alone. Here’s how NASA will at last discover and measure them.

On July 12, 2022, NASA will release the first science images taken with the James Webb Space Telescope. Here’s what to hope for.

Ever since the Big Bang, cataclysmic events have released enormous amounts of energy. Here’s the greatest one ever witnessed.

Here’s what recent DESI measurements suggest — and why it’s too early to update conventional predictions about the Universe’s distant future.

“The X-Files” was not a documentary.

An optical telescope with a massive 20-foot (6-meter) mirror has an eye-popping price tag of $11 billion.

The midwest is particularly filled with them.

Scientists just viewed one of the tiniest, most isolated, lowest-mass galaxies ever found with JWST. Despite all odds, it’s still growing.

Experts answer 10 big questions about the nightmare scenario that could send us back to the pre-Space Age.

Should we be searching for life on other planets, or technology?

The James Webb Space Telescope has chosen 5 targets for its first science release. Here’s what we know on the eve of JWST’s big reveal!

Most potentially hazardous asteroids remain unidentified. NEO surveyor could change that, but only if it’s funded, and soon.

Within the next few decades, we may well have hard evidence for the existence of alien life on worlds light-years distant from Earth.

The TRAPPIST-1 system is a treasure trove of possibilities and questions. Observations by JWST have just begun.

The race to find dark matter could grow more complex with high-energy neutrino interference.

With its very first deep-field view of the Universe now released, the James Webb Space Telescope has shown us our cosmos as never before.

From the tablets of the Babylonians to the telescopes of modern science, humans have always looked to the skies for fundamental answers.

Back in the 1930s, Fritz Zwicky postulated the existence of dark matter. No one took it seriously until Vera Rubin’s work: 40 years later.

To study the origin of the Universe, we could build a constellation of six expensive spacecraft — or we could just use the Moon.

From LIGO, there weren’t enough neutron star-neutron star mergers to account for our heavy elements. With a JWST surprise, maybe they can.

As Marcel Proust said, “The real voyage of discovery… consists not in seeking new landscapes, but in having new eyes.”

Artificial intelligence is much more than image generation and smart-sounding chatbots; it’s also a Nobel-worthy endeavor rooted in physics!

The discovery calls into question the few things scientists know about these powerful astronomical phenomena.

Thanks to time-traveling telescopes, we can see more about the Big Bang.

The James Webb Space Telescope could help scientists learn about the cosmic dark ages and how they ended.

The light from Earendel took 12.9 billion years to reach Hubble. The star is millions of times brighter than our Sun and 50 times as massive.

With its first view of a protoplanetary disk around a newly forming star, the JWST reveals how alone individual stellar systems truly are.

The farther away they get, the smaller distant galaxies look. But only up to a point, and beyond that, they appear larger again. Here’s how.

With a new telescope on the horizon, we reflect on the best pictures of space that came before.

Many planets will eventually be devoured by their parent star. For the first time, we caught a star in the act, eating its innermost planet!
