Astronomers discover missing planets around the galaxy’s most common stars

Astronomers have discovered something surprising about planets beyond our solar system. Even though planets are incredibly common—scientists now estimate there is at least one planet...

Why one side of the Milky Way is hotter than the other

Scientists have discovered a surprising reason why one side of our galaxy is warmer than the other, and the explanation is something you might...

How the Milky Way’s smallest neighbors reveal the early universe

Astronomers have long been fascinated by tiny galaxies that orbit the Milky Way. These faint and fragile systems, known as ultra-faint dwarf galaxies, are often...

Binary stars form lots of exoplanets, but many of them are ejected as rogue...

Astronomers don't have to work hard to find binary stars in the Milky Way. They're common, even abundant. For a long time, they thought that...

Scientists finally discover the true edge of the Milky Way

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...

Potential signs of life on distant planets sound exciting, but confirmation can take years

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...

Astronomers find the edge of the Milky Way’s star-forming disc

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...

Forget our Sun—Planets might form more easily around double stars

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...

Do stars slow down before they die? New study reveals a surprising twist

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...

Young sun-like stars are not as menacing as thought

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...

Curiosity rover uncovers 3.5-billion-year-old organic matter on Mars

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...

Scientists map hidden magnetic fields on the sun’s far side

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...

Deep Space

A dying red giant star has thrown out giant symmetrical loops of gas and...

The Gemini South telescope has captured a new image of the glowing nebula IC 2220. Nicknamed the Toby Jug Nebula, this object got its name...

This mysterious exoplanet shouldn’t exist where it is

Researchers have found an exoplanet that, according to current theories, shouldn’t exist in its current location. Researchers studied the red-giant stars HD 212771 and HD...

Scientists discover a blazar in the early universe

The supersharp radio "vision" of the National Science Foundation's Very Long Baseline Array (VLBA) has revealed previously unseen details in a jet of material...

Scientists map dynamic black hole with light echoes

Although most black holes are too small on the sky for us to resolve their immediate surroundings, we can explore these mysterious objects by...

Clay subsoil at Earth’s driest place may signal life on Mars

Earth’s most arid desert may hold a key to finding life on Mars. Diverse microbes discovered in the clay-rich, shallow soil layers in Chile’s dry...
