“While 3I/ATLAS is a visitor from interstellar space, travelling from outside the Solar System, its behaviour is completely ...

Despite the dramatic name, these alignments aren’t exceptionally rare. The last six-planet parade occurred in January 2025, and a four-planet lineup followed in August 2025. What makes each one feel ...

Remember 3I/ATLAS? Yes, the interstellar comet that made plenty of headlines in 2025 is still romping through our solar system.

Webb maps Uranus’s upper atmosphere, revealing cooling temperatures, shifting auroras, and the effects of its tilted magnetic field.

Fresh observations from the James Webb Space Telescope show how vivid auroras surge through Uranus’s tilted magnetic field ...

A comet whizzing through the Solar System has astonished scientists by doing something they had never seen before. In early 2017, comet 41P/Tuttle-Giacobini-Kresák made its 5.4-year close approach to ...

Comet 3I/ATLAS is already racing back into deep space, but its surprise resurgence in December 2025 has turned a fading curiosity into a case that planetary scientists will be arguing over for years.

First its rotation slowed between March and May 2017, taking 46 hours to complete a spin where it had once taken only 20 hours. This occurred as the comet neared its closest point to the sun, roughly ...

An exoplanetary system about 116 light-years from Earth could flip the script on how planets form, according to researchers who discovered it using telescopes from NASA and the European Space Agency, ...

For millions of years, a frozen wanderer drifted between the stars before slipping into our solar system as 3I/ATLAS—only the third known interstellar comet ever spotted. When scientists turned NASA’s ...

NASA shared some new infrared images of the 3I/ATLAS interstellar comet this week, showing the visitor brightening up in a dramatic outburst while exiting a solar system. The images were taken by the ...

Uranus is the strangest planet in the solar system when it comes to rotation, spinning almost completely on its side. Scientists believe something massive happened early in its history, possibly a ...
