The heights of La Soufrière de Guadeloupe volcano can be hellish, sweltering at more than 48 degrees Celsius (120 degrees Fahrenheit) and swathed in billows of acidic gas.
Researchers would like to monitor gas and steam eruptions at its summit,…

Early Mars Was Covered in Ice Sheets, Not Flowing Rivers
A large number of the valley networks scarring Mars’s surface were carved by water melting beneath glacial ice, not by free-flowing rivers as previously though.
The findings effectively throw cold water on the dominant “warm and wet ancient…

Biodiversity Surrounding the Tibetan Plateau Shows How Climate Change Can Affect Evolution
One of the big questions in biology is why certain plants and animals are found in some places and not others.
Figuring out how species evolve and spread, and why some places are richer in species than others, is key to understanding and…

Asteroid Shower on the Earth-Moon System 800 Million Years Ago Revealed by Lunar Craters
A research team led by Osaka University investigated the formation ages of 59 lunar craters with a diameter of approximately 20 km using the Terrain Camera (TC) onboard the lunar orbiter spacecraft Kaguya.
Kaguya (formerly SELENE, for…
