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

Surprise, it's twins.

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, ...

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 ...

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 ...

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 ...

Illustration comparing the planets of the Solar System and the Sun on the same scale. The planets are shown to scale relative to each other but their distances are not. From left to right the bodies ...

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 ...

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 ...

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 ...
