The decades since scientists confirmed the first planet around another star have been rich in discovery, but it’s rare to see ...

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 ...

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 ...

Mercury, Venus, Earth and Mars – may have formed from two rings around the young sun, rather than a single disc ...

Simulations reveal that Jupiter’s rapid growth disrupted the early solar system, creating rings where new planetesimals formed much later than expected. These late-forming bodies match the ages and ...

An exoplanetary system about 116 light-years from Earth could flip the script on how planets form, according to researchers who discovered it using telescopes from NASA and the European Space Agency, ...

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 ...

Federal funding is about to run out for 19 active space missions studying Earth’s climate, exploring the Solar System, and probing mysteries of the Universe. This year’s budget expires at the end of ...

Scientists say a nearby red dwarf star hosts a planetary lineup that looks like a mirror image of our own solar system, with rocky worlds bookending a pair of gas-rich planets. Around the star LHS ...

The workings of our solar system are roughly the same now as they have been for millions of years. Moons circle their planets, the planets circle the sun, the sun’s magnetic fields and sunspots wax ...

The updated measurements won't take away Jupiter's status as the solar system's biggest planet. NASA / JPL-Caltech / SwRI / MSSS Scientists may have been overestimating the size of the solar system’s ...

At the edge of our solar system, NASA’s Voyager 1 spacecraft has detected a stunning “wall of fire,” a boundary where interstellar space begins. This record 90,000°F barrier, uncovered by the Voyager ...
