The curious minds at What If explore what would happen if Jupiter never existed at all, revealing orbital changes, asteroid risks, and planetary chaos.

The curious minds at What If imagine Jupiter colliding with a black hole in deep space, exploring gravity, destruction, and the physics of extreme cosmic events.

"This is a crucial step towards characterizing giant planets beyond our solar system." ...

Carl Sagan’s quote, “Imagination will often carry us to worlds that never were, but without it we go nowhere,” highlights imagination as the foundation of progress, even when it leads to ideas that ...

For the first time, an international team of astronomers have mapped the vertical structure of Uranus's upper atmosphere, uncovering how temperature and charged particles vary with height across the ...

In late winter, the zodiacal light is visible in the evening in the Northern Hemisphere (false dusk) and in the pre-dawn morning in the Southern Hemisphere (false dawn). In early autumn, the timing ...

Astronomers have long debated why so many icy objects in the outer solar system look like snowmen. Michigan State University ...

The other discovery is the cooling of the atmosphere. Combining the observations from JWST with measurements from Voyager 2, other spacecraft, and ground-based telescopes, it is clear that the ...

On 19 February 2026, Mercury reaches its greatest eastern elongation, while the crescent Moon appears close to Saturn, creating a striking evening display visible across India, North America, and ...

Astronomers have puzzled for years over a strange pattern in the outer solar system. A surprising number of icy bodies far beyond Neptune resemble snowmen, made of two rounded lobes stuck together.

The discovery of interstellar comet 3I/ATLAS last year provided insights into a never-before-seen object. It's different from the two known other interstellar interlopers that we ...

Imagine an object so colossal that, if it occupied the place of our Sun, its surface would extend beyond the orbit of Saturn. Imagine a star that challenges not only the known physical limits, but ...
