The curious minds at What If investigate what would happen if you spent an entire day on Jupiter, revealing gravity, atmospheric pressure, and survival limits.

There are 79 known moons of Jupiter. What if we move Earth into its orbit too? How would Jupiter's super-strong gravity affect our lives? What would our skies look like? How long could you survive on ...

Time moves differently in space. Near black holes, gravity slows clocks and stretches seconds. This explainer reveals how time bends and affects astronauts and Earth.

The simultaneous eruption of multiple volcanoes suggests a vast, interconnected network of magma exists beneath the surface, powered by the intense gravitational pull of Jupiter.

Baby stars, teenage planets, and disappearing icebergs are all featured this week. Plus, a look back at a New Horizons image of Jupiter and Io, and a strange, elongated cloud on Mars.

Despite its small size, Mars seems to have a huge impact on the orbital cycles that govern Earth’s climate, especially those ...

According to the new research, astronomers have employed the Very Large Telescope's technology, known as GRAVITY and have ...

Since this past September, Saturn’s been the best planet to enjoy through even a small telescope, even though its ring system still appears nearly on edge from our vantage on Earth presently. There’s ...

In a new study, scientists used advanced computer models to peer beneath Jupiter's dense swirling cloud tops and tackle a question that has lingered for decades: How much oxygen does the gas giant ...

"Without Mars, Earth's orbit would be missing major climate cycles. What would humans and other animals even look like if ...
