Pluto was discovered in 1930 in Arizona, but in 2006 scientists decided to cut Pluto from the planetary line up. Here is why ...

NEW YORK (AP) — A new Tatooine-like planet outside the solar system may orbit two failed stars ... 3 Chinese astronauts docks ...

a new theory now suggests that the cause could be a 2-50 Jupiter-mass object passing through the Solar System. To start with, the planets formed out of a rotating disk of gas and dust around the ...

The essential features of this hypothesis are that the Solar System has been formed from a spiral nebula, and that the planets have not been detached from the central mass through its rotation but ...

University of Central Florida (UCF) scientists and their collaborators discovered new insights into the formation of distant ...

If you thought planets only circled stars in neat, flat disks, think again. Scientists have uncovered compelling evidence for ...

The Hypothesis of Laplace.According to Laplace, the solar system formerly consisted of a very much flattened mass of gas, extending beyond the orbit of Neptune, and rotating like a rigid body.

“As we study the complex structures in detail, they will reveal important information about the building blocks and ...

Using the James Webb Space Telescope (JWST), scientists analyzed far-away bodies -- known as Trans-Neptunian Objects (TNOs) -- and found varying traces of methanol. The discoveries are helping them ...

Saturn is home to the Solar System’s most epic ice rink ... It takes 243 Earth days for Venus to do one complete rotation, and 225 Earth days to orbit the Sun. Therefore, a day is longer ...

The rotating model, which does not break any known law of physics, suggests the universe could spin around once every 500 billion years. This would be far too slowly to detect easily, but enough to ...
