Mars shines in the evening, and is joined briefly by Mercury. Jupiter joins Venus as the month goes on. And all month, look ...

The NASA/ESA Cassini-Huygens mission explored Saturn and its moons from 2004 to 2017, providing the most detailed images and ...

Stars often whip their planets with solar winds and radiation, pull them ever closer with gravity and sear them with heat.

James Webb’s mid-infrared vision has likely captured a frigid, Saturn-mass planet shaping the dusty rings around the nearby ...

Most disks observed were about 30 astronomical units wide, roughly 30 times the Earth-Sun distance. The presence of intricate structures in such early systems implies a parallel evolution of infant ...

In a stellar nursery 460 light-years away, astronomers sharpened old ALMA data and spotted crisp rings and spirals swirling ...

Yet, recent space missions and planetary research have uncovered a surprising truth: the weather on planets throughout our solar system, and even beyond, often mirrors what we experience here on Earth ...

Using the James Webb Space Telescope (JWST), astronomers have peered deep into one of the Milky Way's most radiation-intense star-forming regions, revealing that Earth-like planets can form even in ...

If there were one, that Planet Nine would "nudge the closest part of 2017 OF201's trajectory inward until Neptune flung it out of the solar system." Because 2017 OF201 is there, that could be an ...

A newly discovered object called 2017 OF201, likely a dwarf planet, travels in an extremely wide elliptical orbit (yellow), a new study suggests. The orbit of the dwarf planets Sedna and Pluto are ...

This process, , is how everything in the solar system – planets, moons, comets and asteroids – came into being. Telescopes can see young solar systems being born.

The long-theorized Planet 9, which astronomers have speculated could be a Neptune-sized planet that has been lurking on the outer edge of the solar system, could explain the unusual clustering and ...
