Are Super-Earths Capable of Creating Conditions That Are Hospitable for Life to Arise and Thrive?

An illustration showing how a combination of static high-pressure synthesis techniques and dynamic methods enabled the researchers to probe the magnesium silicate bridgmanite, believed to be predominate in the mantles of rocky planets, under extreme conditions mimicking the interior of a super-Earth.

Evidence That Earth’s First Cells – 3.8 Billion Years Ago – Could Have Made Specialized Compartments

“Protocells” containing bubble-like compartments formed spontaneously on a mineral-like and encapsulated fluorescent dye. This could have been what happened 3.8 billion years ago when cells first began to form. Credit: Image courtesy of Karolina Spustova New research by the University of Oslo provides evidence that the “protocells” that formed around 3.8 billion years ago, before […]

The Milky Way May Be Swarming With Planets That Have Continents and Oceans Like Earth

“All planets in the Milky Way may be formed by the same building blocks, meaning that planets with the same amount of water and carbon as Earth,” says Professor Anders Johansen.

Lumpy, 30-pound meteorite that crashed in Sweden recovered in local village

A half-melted hunk of iron-rich rock found in Uppsala, Sweden, is part of a meteorite that fell there in November 2020.  The lumpy meteorite is about the size of a loaf of bread and weighs around 31 pounds (14 kilograms), according to the Swedish Museum of Natural History. It was once part of a larger […]

There’s Evidence That Mars Once Had an Atmosphere With Less Oxygen. A Possible Biosignature For Life?

Remote sensing is only useful if scientists have an idea of what they are looking at.  That knowledge is especially important for remote sensing applications on other planets, such as Mars, where it is extraordinarily difficult to collect information about an observed object in any other way.  To make up for the lack of ability […]

Raising the flag on Iwo Jima: Here’s the story behind that iconic World War II photo

On Feb. 23, 1945, during the Battle of Iwo Jima (Feb. 19 to March 26), six Marines planted the U.S. flag at the summit of Mount Suribachi. The scene was photographed by journalist Joe Rosenthal of the Associated Press and his image soon became famous around the world. What many people do not know is […]

New Map of Solar Neighborhood Reveals That Binary Stars Are All Around Us

Gaia survey provides location and motion of 1.3 million binary pairs within 3,000 light years of Earth. The latest star data from the Gaia space observatory has for the first time allowed astronomers to generate a massive 3D atlas of widely separated binary stars within about 3,000 light years of Earth — 1.3 million of […]

Doorknobs That Naturally Destroys Viruses: Biomaterials Could Mean Better Vaccines, Virus-Fighting Surfaces

Researchers are studying the ways biomaterials can be used both to strengthen vaccines to fight viruses in the body and to build surfaces that would fight virus cells that landed on them. Credit: Sushma Kumari Scientists are working toward advances that, using nanotechnology, could lead to a hospital bed or doorknob that naturally destroys viruses. […]
