2022 was another busy year in the realm of science, with groundbreaking stories spanning space, materials, medicine, and technology.
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.
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.
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.
Unexpected images of galaxies from the James Webb Space Telescope do not disprove the Big Bang. There are other likelier explanations.
If there are human-sized creatures walking around on other planets, would we be able to view them directly?
In July of 2022, the first science images from JWST were unveiled. Two years later, it’s changed our view of the Universe.
Archaeologists can learn how societies lived by studying what they left behind when they died. Astronomers are doing much the same thing.
After years of analysis, the Event Horizon Telescope team has finally revealed what the Milky Way’s central black hole looks like.
The James Webb Space Telescope is about to begin science operations. Here’s what astronomers are excited about.
Einstein’s relativity teaches us that time isn’t absolute, but passes relatively for everyone. So how do telescopes see back through time?
With a telescope at just the right distance from the Sun, we could use its gravity to enhance and magnify a potentially inhabited planet.
It was supposed to have a 5.5-10 year lifetime, and take 6 months to calibrate. It’s performing better than anyone anticipated.
Since dark matter eludes detection, the mission will target sources of light that are sensitive to it.
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.
A deep dive into the chaotic journey of star formation.
The first set of James Webb’s images blew us all away. In just 2 mere months, it’s seen highlights that no one could have predicted.
With a finite 13.8 billion years having passed since the Big Bang, there’s an edge to what we can see: the cosmic horizon. What’s it like?
Scientists can make substantial progress without fully understanding exactly what they’re doing.
A true scientific view of if, where, and when extraterrestrial life exists is within our grasp thanks to biosignatures and technosignatures.
When we started imaging the Universe with Hubble, every star had four “spikes” coming from it. Here’s why Webb will have more.
You would think that with all our technology, like the James Webb Space Telescope, we would know how big the Universe is. But we don’t.
Now that it’s fully commissioned, the James Webb Space Telescope begins its exploration of the Universe. Here are its first science images!
In 1924, Edwin Hubble found proof that the Milky Way isn’t the only galaxy in the Universe.
The James Webb Space Telescope (JWST) will study many dangerous cosmic phenomena, knowledge of which may help save humanity.
An optical telescope with a massive 20-foot (6-meter) mirror has an eye-popping price tag of $11 billion.
On July 12, 2022, NASA will release the first science images taken with the James Webb Space Telescope. Here’s what to hope for.
There are billions of potentially inhabited planets in the Milky Way alone. Here’s how NASA will at last discover and measure them.
From the tablets of the Babylonians to the telescopes of modern science, humans have always looked to the skies for fundamental answers.
