Scientists discover ancient seawater preserved from the last Ice Age

Twenty thousand years ago, in the thick of an Ice Age, Earth looked very different. Because water was locked up in glaciers hundreds of feet thick, which stretched down over Chicago and New York City, the ocean was smaller—shorelines ...

Study provides new insight into origin of Canadian Rockies

The Canadian Rocky Mountains were formed when the North American continent was dragged westward during the closure of an ocean basin off the west coast and collided with a microcontinent more than 100 million years ago, according ...

Galaxies as 'cosmic cauldrons'

Star formation within interstellar clouds of gas and dust, so-called molecular clouds, proceeds very rapidly yet highly inefficiently. Most of the gas is dispersed by stellar radiation, revealing galaxies to be highly dynamic ...

Water formation on the moon

For the first time, a cross-disciplinary study has shown chemical, physical, and material evidence for water formation on the moon. Two teams from the University of Hawaiʻi at Mānoa collaborated on the project: physical ...

Galaxy blazes with new stars born from close encounter

The NASA/ESA Hubble Space Telescope has taken a new look at the spectacular irregular galaxy NGC 4485, which has been warped and wound by its larger galactic neighbour. The gravity of the second galaxy has disrupted the ordered ...

Impact of carbon dioxide leakage through North Sea wells

Realistic estimates show that global warming can only be kept below 1.5 or two degrees Celsius if carbon dioxide is actively removed from the atmosphere. Storage beneath the seafloor is an option that has been investigated ...

Suppressed star formation in the early universe

Massive clusters of galaxies, some with more mass than a hundred Milky Way galaxies, have been detected from cosmic epochs as early as about three billion years after the big bang. Their ongoing star formation makes them ...
