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 ...

It may not feel like it, but everything in the universe is in constant motion. Our Sun, with all its planets, orbits the center of the Milky Way, flying through the cosmos at around 450,000 miles per ...

New measurements of radio galaxies reveal that the solar system is racing through the universe at over three times the speed predicted by standard cosmology. Using highly sensitive data from multiple ...

Having made its closest approach to the sun on Wednesday October 29, comet 3I/ATLAS will soon be visible from Earth again—before it leaves our solar system. While the comet—first spotted in July—has ...

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, ...

A massive comet traveling through the solar system is much larger than previously thought and could be a remnant of alien technology, a scientist claims in a new report. 3I/ATLAS was first identified ...

A mysterious object hurtling through space has been identified as a rare “interstellar object,” only the third of its kind ever seen. In July, NASA reported its ATLAS (Asteroid Terrestrial-impact Last ...

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 ...

Astronomers have uncovered a massive new trans-Neptunian object, 2017 OF201, lurking at the edge of our solar system. With an orbit stretching 25,000 years and a size that may qualify it as a dwarf ...

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 ...

While its star projector leaves a lot to be desired, the Science Can Solar System Planetary Projector is a fantastic educational tool for kids, with its solar system model, complete with talking ...

Astronomers have found a septet of superclouds lying just beyond the solar system. These giant strings of gas — five of which were previously unknown — sit nearly parallel to each other, and most of ...
