Revised observations showed it to be about 140 kilometers (87 miles) wide. But that’s still the biggest anyone has ever seen—most comets in the solar system are only one or two kilometers across.

In space terms, our solar system is like a calm pond, but even the smallest pebble can cause ripples. According to the study in Icarus, a passing star within 10,000 astronomical units (AU) could ...

The solar panel frames and mounting rails need to be bonded (connected so that they maintain electrical continuity), and the whole mounting system then needs to be grounded to earth—i.e., with ...

Comet 3I/ATLAS, discovered on July 1, 2025, by the ATLAS telescope in Chile, is only the third confirmed interstellar object observed in our solar system. The comet is traveling at an extraordinary ...

NASA's PUNCH mission has unveiled its first images of colossal solar eruptions known as coronal mass ejections (CMEs) — delivering an unprecedented, wide-field view of how these solar storms ...

The European Space Agency’s (ESA’s) Solar Orbiter is out of alignment with the rest of the Solar System. And that’s a good thing. By orbiting the Sun outside of the Solar System’s orbital plane, the ...

Solar Orbiter used a slingshot flyby around Venus in February to get out of this plane to view the sun from up to 17 degrees below the solar equator. Future slingshot flybys will provide an even ...

Here's everything you need to know before taking the leap. Do solar panels make it harder to sell your house? Most of the time, they don't. "Overall, they're perceived as a value, because they're ...
