New simulations suggest that up to four of the solar system's rocky planets, including Earth and a long-lost world, once ...

"We believe that continuing such activities will further expand our horizon in the field of planetary science." ...

With shared features across rocky planets, scientists explore whether Venus and Mars could someday become snowball planets, echoing Earth's ancient climate collapse.

During the early days of our solar system, giant impacts were common occurrences. Earth likely experienced such an impact ...

The Brief A piece of a failed 1972 Soviet Venus probe is expected to reenter Earth around May 10. The object could fall anywhere between 52° North and 52° South, covering a wide area. Experts ...

Venus currently hosts 20 known co-orbitals, including "Trojan" asteroids and the peculiar quasi-moon Zoozve. These objects, each exceeding 460 feet in diameter, could devastate urban areas if they ...

“There is a range of orbits with eccentricities lower than 0.38 for which Venus’ co-orbitals can pose a collisional hazard to Earth,” scientists wrote.

Yet, despite using the JWST's sensitive Near-Infrared Spectrometer, or NIRSpec, astronomers led by Piaulet-Ghorayeb found no ...

Stargazers hoping to catch sight of August's Venus-Jupiter Conjunction should keep their eyes to the skies on Tuesday morning. From Earth, both planets shine the brightest and will appear together ...

Venus and Jupiter, the brightest planets in our solar system, are about to make their closest approach during their August conjunction.

“We know that on Earth there are long-term atmospheric cycles, so it could happen on Venus as well. We can’t dismiss this possibility at the moment.” Volcanoes, however, are a lot more likely.
