What happens when a star gets too close to a black hole
Supermassive black holes are among the most enigmatic objects in the universe.
They typically weigh millions or even billions of times the mass of the...
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...

Scientists discover Earth-like auroras on Jupiter’s giant moon
Scientists have discovered that the colorful light shows seen above Earth’s poles also occur on Ganymede, Jupiter’s largest moon—and they behave in strikingly similar...
NASA confirms thousands of massive, ancient volcanic eruptions on Mars
Scientists found evidence that a region of northern Mars called Arabia Terra experienced thousands of “super eruptions,” the biggest volcanic eruptions known, over a...
Astronomers find stunning birthplace of cosmic “buckyballs” in deep space
Astronomers have captured stunning new images of a distant cloud of gas and dust where unusual molecules called “buckyballs” are formed.
Using the powerful James...
Two surprising findings about water on Mars
A new analysis of seismic data from the InSight mission to Mars has revealed some surprises.
The first: the top 300 meters of the subsurface beneath...
Scientists see evidence of Einstein’s theories in star orbiting massive black hole
More than 100 years ago, Albert Einstein predicted that light is deflected by extremely massive objects, but there is no way to test such...
