A billion years ago, days lasted 19 hours: the balance between the oceans, the atmosphere, and the Moon slowed down the Earth ...

Scientists have traced the origins of complex life to the breakup of the supercontinent Nuna 1.5 billion years ago. This tectonic shift reduced volcanic carbon emissions, expanded shallow seas, and ...

In 1974, the project’s Science Working Group recommended that the telescope be required to resolve details at least one-tenth ...

NASA has just revealed enormous cracks, or grabens, on the Moon that show how the Mare Humorum fractured billions of years ...

The “Boring Billion” is an informal description of a billion-year-period of Earth history (1.8 billion to 800 million years ago) where tectonics, climate, and biological evolution remained ...

The James Webb Space Telescope and other international observatories have spotted a 13-billion-year-old supernova. On Tuesday, the European Space Agency (ESA) announced the sighting of a gamma-ray ...

Astronomers in India say their discovery of a massive galaxy from when the Universe was only 1.5 billion years old challenges our understanding of how galaxies were formed in the early period after ...

Relative plate motions and plate boundary geometries are from Cao et al. (2024), with plate motions placed in a mantle reference frame. Continents are light grey, with continental margins shown in ...

Researchers have discovered chemical traces of life in rocks older than 3.3 billion years, offering a rare look at Earth’s earliest biology. By combining advanced chemical methods with artificial ...

Ancient supercontinent Nuna's breakup around 1.5 billion years ago set off a chain of events that made Earth more habitable, new research suggests. When you purchase through links on our site, we may ...
