Astronomers finally crack the mass mystery of Orion’s hidden young stars
A star’s mass shapes everything about its life, from how bright it shines to how it eventually dies.
Small stars like our Sun burn slowly...
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 discover waves on Titan could shape its shorelines
Titan, Saturn's largest moon, is the only other body in our solar system that has active rivers, lakes, and seas.
These rivers are believed to...
JWST studies reveal details of gas outflows in merging galaxy nearby
The James Webb Space Telescope (JWST) has given astronomers a remarkable new view of NGC 3256, a galaxy undergoing a dramatic transformation.
This galaxy, situated...
Scientists crack 1.4-billion-year-old salt crystals to reveal Earth’s ancient air
More than a billion years before dinosaurs—and long before plants and animals—Earth looked very different.
In what is now northern Ontario, a shallow, salty lake...
Cosmic web lights up in the darkness of space, shows study
The universe is much like an intricate web, woven with invisible threads connecting galaxies, called the cosmic web.
This web is made of gas streams,...
Earth is faster, closer to supermassive black hole in new map of galaxy
Earth just got 7 km/s faster and about 2000 light-years closer to the supermassive black hole in the center of the Milky Way Galaxy.
But...
