Oct. 7, 2024 — Planet-forming disks, maelstroms of gas and dust swirling around young stars, are nurseries that give rise to planetary systems, including our solar system. Astronomers have ...

“The best match for today's outer solar system that we found with our simulations is a star that was slightly lighter than our Sun – about 0.8 solar masses,” said Amith Govind, co-author of ...

The gravitational attraction between two objects decreases with distance. This means that the closer the two objects are to each other, the stronger the force of gravity between them. If the force ...

Astronomers have discovered an exoplanet about half the size of Venus orbiting Barnard’s star, the closest single star to our ...

We now know that black holes occur frequently throughout the universe. One Sagittarius A* sits at the center of our galaxy, ...

Planet-forming disks, maelstroms of gas and dust swirling around young stars, are nurseries that give rise to planetary systems, including our solar system. Astronomers have discovered new details of ...

Here’s how it works. A passing star may be responsible for more than three-fourths of the moons in our solar system as the stellar traveler flung massive rocky bodies into our cosmic ...

In 2017, researchers identified the first object from another star to enter our solar system, which had far less mass than a microscopic black hole would. Whether or not they detect a passing ...

The Sun is the largest object in the Solar System. The Sun’s huge gravitational field keeps many other objects – planets, dwarf planets, asteroids and comets – in orbit around it.
