SpaceX launched a new GPS satellite to orbit for the US military, continuing an effort to bolster a constellation of global positioning and navigation satellites that underpin smartphone apps, wartime operations, and more.

A new study of Greenland’s ice cores indicates that rising temperatures bear the ‘clear signature of global warming’.

Perseverance has now completed its investigation of the atmosphere throughout the first Martian year (which lasts approximately two Earth years). Specifically, astronomers have studied seasonal and daily cycles of temperature and pressure, as well as their si…

When the mercury drops, mammals like us have an advantage over so-called cold-blooded critters; our muscles can act as furnaces, generating the heat needed to keep our body temperature stable by turning fuel into movement.

At around 12 billion years old the stars in the ultra-faint galaxies formed less than 2 billion years after the Big Bang.

Neanderthals in Combe-Grenal (France) preferred to hunt in open environments, and their hunting strategies did not alter during periods of climatic change, according to a study published in PLOS ONE by Emilie Berlioz of the CNRS/Université Toulouse Jean Jaurè…

A new computational system uses satellite data to identify sites on land where people dispose of waste, providing a new tool to monitor waste and revealing sites that may leak plastic into waterways. Caleb Kruse of Earthrise Media in Berkeley, California, Dr.…

Mycorrhizal symbiosis helps plants expand their root surface area, giving plants greater access to nutrients and water. Although the first and foremost role of mycorrhizal symbiosis is to facilitate plant nutrition, how mycorrhizal types mediate the nutrient …

Scientists have shed new light on the "self-cleaning" capacity of the atmosphere.

Engineers at CU Boulder have designed a new kind of film, made from layers of stretchy materials called “liquid crystal elastomers,” that can leap all on its...

The process of defining the scientific objectives of these large observatories is complex and comprehensive

Scientific Reports - Topologically protected plasmonic phases in randomized aperture gratings

Australia's echidnas have developed a curious way to cool off — blowing bubbles. This and other techniques can help the spine-covered mammals beat the heat, something that may be more needed as temperatures rise due to the climate crisis.

Astronauts are heading back to the moon, and this time they are focusing on establishing the first long-term presence. Afterward, NASA has its sights set on a trip to Mars.

Greenland’s ice sheet could cause up to 20 inches of global sea-level rise by the end of the century, researchers warn.

Deep inside all matter in the universe, electrons are buzzing around and behaving as if they are twirling around on their axes like spinning tops. These "spinning" electrons are fundamental to quantum physics and play a central role in our understanding of at…

This donut-shaped ring of gas that used to be a star can tell astronomers about the supermassive black hole that molded it.

Scientists have used the Hubble telescope to capture images of the Butterfly Nebula, giving a glimpse of how our star will look after death.

Electron spins reflect chiral molecules without the mirror.

By Ashley Strickland, CNN Australia’s echidna has developed a curious way to cool off — blowing bubbles out of its beaklike snout. The short-beaked echidna is common across Australia, Tasmania and New Guinea and along with the platypus, it’s one of Earth’s fe…

A new study by University of Central Florida researchers has found strong evidence that the outgassing of molecules from comets could trace the chemical

Astronomers have begun using a sophisticated suite of simulations, an advanced machine learning model of the formation of galaxy clusters, and an exotic relationship between galaxies to understand the origins of dark matter and dark energy.

Future historians might look back on this time and call it the "exoplanet age." We've found over 5,000 exoplanets, and we'll keep finding more. Next, we'll move beyond just finding them, and we'll turn our efforts to finding biosignatures, the special chemica…

Antarctica is a tough place to work, for obvious reasons— it’s bitterly cold, remote, and wild. However, it’s one of the best places in the world to hunt for meteorites.
