Using...
How can this tiny world have an atmosphere? Scientists are stunned
Far beyond Neptune, in one of the coldest and darkest regions of our solar system, astronomers have discovered something unexpected: a small icy object...
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...

Astronomers using NASA's Hubble Space Telescope have made a unique measurement that indicates a jet, plowing through space at speeds greater than 99.97% the...
Scientists find the 5000th exoplanet
Since the first discovery of a planet outside our solar system 30 years ago, thousands more have been found.
At first, discoveries of these new...
Scientists may have discovered first planet to orbit 3 stars
In a distant star system — a mere 1,300 light years away from Earth — UNLV researchers and colleagues may have identified the first...
The Milky Way’s last merger event was more recent than thought
The Milky Way is only as massive as it is because of collisions and mergers with other galaxies. This is a messy process, and...
