Temperatures in the Sun's core exceed 10 million degrees Celsius. But how on Earth did we actually come to know that?
With a telescope at just the right distance from the Sun, we could use its gravity to enhance and magnify a potentially inhabited planet.
Sometimes, going "deeper" doesn't reveal the answers you seek. By viewing more Universe with better precision, ESA's Euclid mission shines.
Scientists may have detected the somewhat smelly chemical dimethyl sulfide on a planet 120 light-years from Earth.
An optical telescope with a massive 20-foot (6-meter) mirror has an eye-popping price tag of $11 billion.
The nearby, bright star Fomalhaut had the first optically imaged planetary candidate. Using JWST's eyes, astronomers found so much more.
With a new telescope on the horizon, we reflect on the best pictures of space that came before.
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.
From the tablets of the Babylonians to the telescopes of modern science, humans have always looked to the skies for fundamental answers.
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.
The James Webb Space Telescope (JWST) will study many dangerous cosmic phenomena, knowledge of which may help save humanity.
Now that it's fully commissioned, the James Webb Space Telescope begins its exploration of the Universe. Here are its first science images!
On July 12, 2022, NASA will release the first science images taken with the James Webb Space Telescope. Here's what to hope for.
Most potentially hazardous asteroids remain unidentified. NEO surveyor could change that, but only if it's funded, and soon.
To study the origin of the Universe, we could build a constellation of six expensive spacecraft — or we could just use the Moon.
There are billions of potentially inhabited planets in the Milky Way alone. Here's how NASA will at last discover and measure them.
The James Webb Space Telescope could help scientists learn about the cosmic dark ages and how they ended.
Since dark matter eludes detection, the mission will target sources of light that are sensitive to it.
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.
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!
How fast is the Universe expanding? Two major methods disagree. New JWST data, just released, strengthens this Hubble tension even further.
From when its light was emitted, the El Gordo galaxy cluster might be the most massive object in all of existence. Here's how JWST sees it.
