Recent simulations and research have unveiled a fascinating new insight into the history of the solar system’s terrestrial ...

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

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

For decades, Venus, often dubbed “Earth’s twin,” has been depicted as a barren, inhospitable world, its surface locked in an unchanging, oven-hot state. Yet, recent data from NASA’s ...

The recent fall to Earth of a failed Soviet Venus probe from the 1970s has become a detective story of sorts. Different computer models were used to predict the reentry.

The solar system’s smallest planet is just now becoming visible before dawn. Bright Jupiter and Venus point the way.

“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.

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 ...

“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.
