Small sulfate aerosol may have masked effects of climate change in 1970s
Small sulfate particles of diameters 0.4 µm or less from anthropogenic sources could have had a cooling effect on the climate in the 1970s, by triggering cloud formation and reflection radiation.

The asteroid that formed Vredefort crater was bigger than previously believed
About 2 billion years ago, an impactor hurtled toward Earth, crashing into the planet in an area near present-day Johannesburg, South Africa. The impactor—most likely an asteroid—formed what is today the biggest crater ...

Models oversimplify how melting glaciers deform land
Around 21,000 years ago, ice sheets retreated from the Northern Hemisphere, and great swaths of land were unburdened by the weight of glaciers. Even today, Earth's shape is still changing as the land rebounds, causing effects ...

Assembling the first global map of lunar hydrogen
Using data collected over two decades ago, scientists from the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, have compiled the first complete map of hydrogen abundances on the Moon's surface. The map ...

When did the sun blow away the solar nebula?
The story of our solar system's origin is pretty well known. It goes like this: the sun began as a protostar in its "solar nebula" over 4.5 billion years ago. Over the course of several million years, the planets emerged ...

Weathering rocks hold clues to Earth's Great Oxidation Event
About 2.4 billion years ago, Earth's atmosphere underwent what is called the Great Oxidation Event (GOE). Prior to the GOE, early Earth had far less molecular oxygen than we have today. After the GOE, molecular oxygen began ...

NASA identifies likely locations of the early molten moon's deep secrets
Shortly after it formed, the moon was covered in a global ocean of molten rock (magma). As the magma ocean cooled and solidified, dense minerals sank to form the mantle layer, while less-dense minerals floated to form the ...

Russian Arctic warming leads to major ice loss
Glaciers and ice caps in two archipelagos in the Russian Arctic are losing enough meltwater to fill nearly five million Olympic-size swimming pools each year, research shows.

Lightning strikes will more than double in Arctic as climate warms
In 2019, the National Weather Service in Alaska reported spotting the first-known lightning strikes within 300 miles of the North Pole. Lightning strikes are almost unheard of above the Arctic Circle, but scientists led by ...
