Most planet-forming disks have warps that can lead to planets on inclined orbits, which could explain where the tilt of Earth ...

This video explores how long it really takes to reach the outer planets: Jupiter, Saturn, Uranus, and Pluto by tracing past missions, their routes, and the engineering trade-offs between speed, fuel, ...

The coldest planet in the Solar System is Uranus, which is surprisingly colder than Neptune due to its unique internal heat ...

The solar system lost its ninth planet back when Pluto was demoted to a dwarf planet, but research might indicate that there ...

Recently, the field of astronomy has been quite lively, as new discoveries from Kepler data have directly overturned our previous understanding of planetary orbits!

Astronomers have directly spotted a rare young planet, WISPIT 2b, still forming within the gap of a dusty ringed disk around ...

Could a vagabond giant from the outermost regions of interstellar space be poised on the cusp of sweeping by our cosmic doorstep? Astronomers say yes and they have the data to support it. Using the ...

Astronomer and Pluto mission leader S. Alan Stern explores how the field has transformed during his decades-long career.

One of the boldest dreams in modern astronomy is the search for Earth-like worlds beyond our solar system. These exoplanets ...

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 earliest images of 3I/ATLAS, newly uncovered by Michigan State University, reveal how the interstellar object evolved as ...

Introduces the solar system and its nine planets. Includes directions for making two models: one showing relative sizes of the planets and the other, their relative distances from the sun.
