From here on Earth, looking farther away in space means looking farther back in time. So what are distant Earth-watchers seeing right now?
Questions about our origins, biologically, chemically, and cosmically, are the most profound ones we can ask. Here are today's best answers.
Dust is ubiquitous in the modern Universe, appearing in nearly all galaxies. But our cosmos was born dust-free. So where does it originate?
Designed to map galaxies, the SPHEREx mission's first science result is instead about interstellar interloper 3I/ATLAS. No, it's not aliens.
First 'Oumuamua, then Borisov, and now ATLAS have shown us that interstellar interlopers are real. Here's what the newest one teaches us.
Once every 12 years, Earth, Jupiter, Uranus, and Neptune all line up, opening a window for a joint mission. Our next chance arrives in 2034.
In just its first 10 hours of observations, the Vera Rubin observatory discovered more than 2000 new asteroids. What else will it teach us?
Launched in March, the PUNCH mission has viewed two incredible coronal mass ejections, tracking them farther from the Sun than ever before.
Our scientific instruments are constantly improving, revealing nature's workings as never before. Without them, we'll remain in the dark.
There are some 26 fundamental constants in nature, and their values enable our Universe to exist as it does. But where do they come from?
New telescopes, radio dishes, and gravitational wave detectors are needed for next-generation science. Will the USA lead the way?
Since mid-2022, JWST has been showing us how the Universe grows up, from planets to galaxies and more. So, what's its biggest find of all?
There was a lot of hype and a lot of nonsense, but also some profoundly major advances. Here are the biggest ones you may have missed.
NASA's space telescopes and observatories bring humanity unrivaled science images and scientific discoveries. Here's what should be next.
More than two years after JWST began science operations, our Universe now looks very different. Here are its biggest science contributions.
Could life be widespread throughout the cosmos, in the subsurface oceans of ice-covered worlds? NASA's Europa Clipper mission investigates.
National Geographic's first James Webb Space Telescope book shows us the cosmos like never before.
In July of 2022, the first science images from JWST were unveiled. Two years later, it's changed our view of the Universe.
There are many theories of gravity out there, and many interpretations of wide binary star data. What have we really learned from it all?
Our Universe requires dark matter in order to make sense of things, astrophysically. Could massive photons do the trick?
The cosmic scales governing the Universe are almost unbelievably large. What if we shrunk the Sun down to be just a grain of sand?
The Universe is an amazing place. Under the incredible, infrared gaze of JWST, it's coming into focus better than ever before.
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!
In the largest star-forming region close to Earth, JWST found hundreds of planetary-mass objects. How do these free-floating planets form?
The laws of physics don't prefer matter over antimatter. So how can we be certain that distant stars & galaxies aren't made of antimatter?
Einstein's laws of gravity have been challenged many times, but have always emerged victorious. Could wide binary stars change all that?
A surprising JWST discovery around Fomalhaut has a different, superior explanation: not a great dust cloud, but a mere background object.
Massive objects like black holes, stars, and rogue planets routinely pass near our Solar System. An ensuing comet storm could destroy us.
Human beings are tiny creatures compared to the 92 billion light-year wide observable Universe. How can we comprehend such large scales?
