Planet Earth. The tardigrade, also known as the water bear, is the toughest, most resilient, form of life on Earth. Credit: © timothyh / Fotolia The world’s most indestructible species, the tardigrade, an eight-legged micro-animal, also known as the water bear, will survive until the Sun dies, according to a new Oxford University collaboration. The

Before the low oxygen period, bivalves were larger and more numerous. Credit: The University of Texas at Austin/Rowan Martindale Using a combination of fossils and chemical markers, scientists have tracked how a period of globally low ocean-oxygen turned an Early Jurassic marine ecosystem into a stressed community inhabited by only a few species. The research

Scientists ask how it’s possible that certain coral reefs are thriving in this location. Credit: Amy Baco-Taylor Scientists have long believed that the waters of the Central and Northeast Pacific Ocean were inhospitable to deep-sea scleractinian coral, but a Florida State University professor’s discovery of an odd chain of reefs suggests there are mysteries about

As the light from the star passes through the Earth’s atmosphere some of it is absorbed in the ozone layer. This results in a clear feature that can be seen using telescopes like JWST. Venus, however, has no ozone layer so the feature is absent. Credit: J Barstow Almost 2000 exoplanets have been discovered to

This is an artist’s impression of a young star surrounded by a protoplanetary disk in which planets (not shown to scale) are forming. Credit: Illustration: ESO/L. Calçada A new model giving rise to young planetary systems offers a fresh solution to a puzzle that has vexed astronomers ever since new detection technologies and planet-hunting missions

Taken from the International Space Station in 2016, this picture of the southern tip of Greenland shows the island’s vast ice sheet fringed by glaciers that flow into the sea. The glaciers and ice sheet of Greenland cover a land area greater than the European countries of Germany, France, Spain and Italy combined. If all

Titan is Saturn’s largest moon. Its cloudy appearance comes from an atmosphere mixed with gaseous nitrogen and hydrocarbons.

New research led by The University of Texas at Austin has found that
