As Uranus approaches its solstice, its polar caps, rings, and moons come into their best focus ever under JWST’s watchful eye. See it now!

From size to mass to density and more, each world in our Solar System is unique. When we compare them, the results are truly shocking.

Adams was infamously scooped when Neptune was discovered in 1846. His failure wasn’t the end, but a prelude to a world-changing discovery.

Voyager 2 flew past Uranus in 1986, finding a bland, featureless world. Now, in 2023, JWST’s sights are similar. There’s a reason for that.

The outer planets’ clouds hide the weirdness within.

From the coldest planets to spacecraft that have exited the Solar System, these little-known facts stump even many professional astronomers.

For now, our Solar System’s eight planets are all safe, and relatively stable. Billions of years from now, everything will be different.

While Saturn and its moons all appear faint and cloudy to JWST, Saturn’s rings are the star of the show. Here’s the big scientific reason.

We’ve only seen Uranus up close once: from Voyager 2, back in 1986. The next time we do it, its features will look entirely different.

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.

The Universe is an amazing place. Under the incredible, infrared gaze of JWST, it’s coming into focus better than ever before.

Although many of Einstein’s papers revolutionized physics, there’s one Einsteinian advance, generally, that towers over all the rest.

This research team is working out how to detect extraterrestrial cells in the liquid water ocean hidden beneath Enceladus’s icy crust.

Newton thought that gravitation would happen instantly, propagating at infinite speeds. Einstein showed otherwise; gravity isn’t instant.

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

Newborn stars are surrounded only by a featureless disk. Debris disks persist for hundreds of millions of years. So when do planets form?

The space telescope’s findings challenge the notion of a galaxy brimming with life.

The existence of another watery world in the outer solar system may offer clues to how such seas form — and hope for another spot to search for life.

Human beings are tiny creatures compared to the 92 billion light-year wide observable Universe. How can we comprehend such large scales?

The classic picture of Jupiter’s great rocky core might be entirely wrong.

The giant impact theory suggests our Moon was formed from proto-Earth getting a Mars-sized strike. An exoplanet system shows it’s plausible.

Do you think you know the Solar System? Here’s a fact about each planet that might surprise you when you see it!

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!

Gravitation, all on its own, can reveal what’s present in the cosmos like nothing else.

The story of how Jupiter, Saturn, Uranus and Neptune were made isn’t a universal one. Some gas giants were built different.

No planet enters retrograde more frequently than Mercury, which does so 3-4 times each year. Here’s the scientific explanation for why.

The secret ingredient is violence, and it just might indicate that “moonmoons” aren’t as uncommon as most astronomers think.

Get ready for the most peculiar road trip that will help you understand the vastness and emptiness of the solar system — and Sweden.

It would get rid of our hazardous, radioactive, and pollutive waste for good, but physics tells us it’s a losing strategy for elimination.
