New Study Rocks Jupiter's Giant Impact Theory

Scientists thought they had Jupiter figured out until NASA's Juno spacecraft peered inside our Solar System’s largest planet and discovered something completely unexpected. Jupiter doesn't have the solid, well defined core that researchers had imagined, instead, Jupiter's core is mysteriously fuzzy and blurred, defying everything we thought we knew about how giant planets form. Now, powerful computer simulations are overturning the leading theory about how this strange structure came to be, suggesting that Jupiter's secrets run deeper than anyone realised.

What's the Earliest the Moon Could Have Formed?

Astronomers are pretty sure they know where the Moon came from. In the early Solar System, a Mars-sized object dubbed Theia smashed into Earth. This cataclysmic collision knocked a huge mass of material into orbit, which coalesced and cooled into the Moon. But establishing exactly when this occurred is a difficult task. At the 55th … Continue reading "What's the Earliest the Moon Could Have Formed?"

Earth’s atmosphere may have originated from a giant impact about 4.4 billion years ago. The impact involved a Mars-sized object hitting Earth, which would have vaporized part of Earth’s mantle and crust, creating a thick silicate vapor atmosphere. This atmosphere would have gradually cooled and condensed into a magma ocean, releasing gases such as water vapor, carbon dioxide, nitrogen, and sulfur.

Scientists discover a way Earth's atmosphere cleans itself

Human activities emit many kinds of pollutants into the air, and without a molecule called hydroxide (OH), many of these pollutants would keep aggregating in the atmosphere.
