For many years, astronomers have wondered where the Milky Way truly “ends.” Unlike a solid object, our galaxy does not have a clear boundary. Its...

Astronomers can use telescopes to find specific molecules in the atmospheres of neighboring planets, in nebulae—clouds of interstellar dust and gas—hundreds or thousands of...

Where exactly is the edge of the Milky Way? That question is harder to answer than one might expect. Since we’re inside of the galaxy...

For a long time, scientists believed that having two stars in one system would make it difficult for planets to form. The strong gravitational pull...

Stars may look calm and steady in the night sky, but deep inside they are constantly moving and changing. One of the most important changes...

Scientists know that the behaviour of stars can dictate planetary habitability. Research shows that young stars emit powerful radiation that can strip planetary atmospheres away. And...

NASA’s Curiosity rover has discovered a surprising variety of organic molecules on Mars, including chemicals that scientists consider important building blocks for life on...

From Earth, we only ever see half of the sun. The other half—the far side—is always hidden from view. But what happens there still matters. Powerful...

A star’s mass decides almost everything about its life, from how bright it shines to how it eventually dies. But for young stars hidden deep...

Astronomers have discovered a distant planet similar to Jupiter that may be covered with thick clouds, offering new insights into how giant planets form...

Fungi are already known for being tough, but new research suggests that some types might be strong enough to survive the long and harsh...

Scientists have found new evidence that Mars may once have been home to a vast ocean covering about one-third of the planet. The discovery comes...

NASA's Hubble Space Telescope has directly photographed evidence of a Jupiter-like protoplanet forming through what researchers describe as an "intense and violent process." This discovery...

An international team of astronomers reports they have found the first faint, low-frequency whispers that may be gravitational waves from gigantic, colliding black holes...

One of the main objectives of the James Webb Space Telescope (JWST) is to study the early Universe by using its powerful infrared optics...

Imagine a giant cosmic factory where planets are born. That's what astronomers have recently observed, and it's pretty exciting! Using a powerful telescope in Chile, they've...

Scientists have used the James Webb Space Telescope (JWST) to uncover a hidden layer of dust in a galaxy 70 million light-years away. This discovery,...
