Astronomers found an atmosphere where they least expected it—clinging to an exoplanet that’s too small, too hot and too old to have air, at least in theory. James Webb Space Telescope (JWST) observations of the blazing-hot lava planet TOI-561 b suggest not only that it has a thick atmosphere but also that it may have had one for billions of years.

Fast-forward to today: we’ve gone from one lonely planet to a catalog of thousands. The pace is accelerating. In 2015, NASA’s Kepler telescope had confirmed its 1,000th exoplanet. By 2022, the tally hit 5,000. Just three years later, we’re at 6,000 — and there are more than 8,000 candidates waiting for confirmation.

Earth is the only planet in our solar system with a single moon, making it a rare phenomenon for a planet of its kind.

On Sept. 18, 1977, NASA's Voyager 1 spacecraft took a photo of Earth and the moon. It was the first time both the Earth and the moon were captured in a single frame. At the time, Voyager 1 was more than 7 million miles away from Earth.

The three satellites look to measure mysteries of space weather while also acting as a warning system for its dangerous effects.

Analysis by researchers at the University of Bern suggests that water and other volatile compounds arrived on Earth from outer space—specifically via a collision with a Mars-sized planet billions of years ago.

Just as passengers don’t feel the plane’s speed while smoothly cruising, we don’t feel Earth’s movement because we’re traveling at the same speed as our planet. You, your chair, the trees, buildings, oceans – everything is moving together with the Earth.
