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.
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.
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.
Gravitation, all on its own, can reveal what's present in the cosmos like nothing else.
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.
Newton thought that gravitation would happen instantly, propagating at infinite speeds. Einstein showed otherwise; gravity isn't instant.
The story of how Jupiter, Saturn, Uranus and Neptune were made isn't a universal one. Some gas giants were built different.
Do you think you know the Solar System? Here's a fact about each planet that might surprise you when you see it!
Within the next few decades, we may well have hard evidence for the existence of alien life on worlds light-years distant from Earth.
Human beings are tiny creatures compared to the 92 billion light-year wide observable Universe. How can we comprehend such large scales?
The space telescope's findings challenge the notion of a galaxy brimming with life.
No planet enters retrograde more frequently than Mercury, which does so 3-4 times each year. Here’s the scientific explanation for why.
The classic picture of Jupiter's great rocky core might be entirely wrong.
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!
The giant impact theory suggests our Moon was formed from proto-Earth getting a Mars-sized strike. An exoplanet system shows it's plausible.
The secret ingredient is violence, and it just might indicate that "moonmoons" aren't as uncommon as most astronomers think.
Water is vital for life. Luckily for spacefaring humans, the solar system is full of it.
Science is for everyone, even those possessing strongly held beliefs that seem to conflict with the best available evidence.
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.
Neptune holds records in our Solar System, but the Universe gets even faster. Here on Earth, extreme weather events can cause dramatic wind speed spikes. When hurricanes are at their most […]
In terms of the planets we've discovered, super-Earths are by far the most common. What does that mean for the Universe?
Get ready for the most peculiar road trip that will help you understand the vastness and emptiness of the solar system — and Sweden.
If there are human-sized creatures walking around on other planets, would we be able to view them directly?
Every observation out into deep space is also a look back in time. Whenever you observe an object, you aren’t viewing it in its present state. When one of Jupiter’s moons […]
You might be inclined to modify gravity instead, but those ideas have grossly unequal evidence supporting them. What is it, exactly, that you’re supposed to do when the predictions of […]
