Updated measurements from NASA’s Juno spacecraft could help researchers better understand the planet's mysterious interior, ...

Gas giants possibly developed slowly in the solar system. They developed cores layer by layer within a disk of ice and dust ...

Gas giants are large planets mostly composed of helium and/or hydrogen. Although these planets have dense cores, they don't ...

Jupiter, without a doubt, is ⁠the biggest planet in our solar system. But it turns out that it is not quite as large – by ...

Jupiter is the largest planet in our Solar System and the fifth planet from the Sun. It is a massive gas giant made mostly of hydrogen and helium, the same elements that form stars.

For over 50 years, we thought we knew the size and shape of Jupiter, the solar system's largest planet. Now, Weizmann Institute of Science researchers have revised that knowledge using new data and ...

96% of our universe is missing, our galaxy should have already been colonized by aliens 1000 times and the solar system might have a hidden 9th planet that’s 10x the size of Earth.

Hubble observations reveal a giant, turbulent planet-forming disk that may reshape theories of how planetary systems develop.

Jupiter, the largest planet in the solar system, isn’t exactly the size and shape scientists believed it was. New measurements from the Juno spacecraft show ...

Typically, from what astronomers have gathered thus far, star systems follow a tidy logic: small, rocky worlds huddle close to the warmth of their star, while massive gas giants bloat up in the colder ...

Gas giants are large planets mostly composed of helium and/or hydrogen. Although these planets have dense cores, they don’t ...

The Oort Cloud is often described as the outermost boundary of the solar system, but its true role remains uncertain. This vast, invisible region of icy objects may extend far beyond the orbits of ...
