Earth may owe some of its properties to a nearby star that blew up just as the solar system was forming. This pattern, which saw a supernova bubble envelop the sun and shower it with cosmic rays, may ...

The comet is the third object ever confirmed to have entered our cosmic neighborhood from elsewhere in the galaxy. Space telescopes and orbiters have been documenting the rare visit. A mysterious ...

NASA’s Goddard Space Flight Center shared the images of comet 3I/ATLAS. It's possibly as big as Manhattan, likely older than our own solar system and it's traveling through space at speeds of up to ...

Material around Chiron, a small icy world in the far reaches of the solar system, may be taking shape into a ring system of its own. The rare event is unfolding in real time, giving astronomers a ...

Last month, Google quietly killed off Google Sky Maps. But there’s still another way to virtually explore most of the solar system a la Google Maps: it’s called Google Maps in Space. Google Maps in ...

Voyager 1, launched in 1977, has traveled farther than any spacecraft in human history. After more than four decades of silent endurance through space, it now sails beyond the orbit of the outer ...

A new analysis estimates that the asteroid belt is steadily losing mass each year, and may not be as permanent a feature of the solar system as we thought. When you purchase through links on our site, ...

Our solar system is a smashing success. A new study suggests that from its earliest period — even before the last of its nebular gas had been consumed — Earth’s solar system and its planets looked ...

The National Aeronautics and Space Administration has confirmed an interstellar object is passing through our solar system. The object is a comet hailing from the direction of the constellation ...

The Solar System, consisting of giant planets, millions of asteroids and a Sun, has a boundary. Yes, like all countries on Earth, the Solar System too has a region after which its dominion ends. This ...

Ever since a mysterious interstellar object, since dubbed 3I/ATLAS, was first spotted screaming into our solar system this year, famed Harvard astrophysicist Avi Loeb has been raising the possibility ...

A team of scientists at the Southwest Research Institute, using photography commissioned from NASA's James Webb Space Telescope, have discovered a previously unknown moon in our solar system that's in ...
