Land animals evolved from ocean ancestors—new study unravels the genetics behind the transition

The transition from water to land is a question that still intrigues scientists. Those ancient organisms would have needed to adapt to several new challenges to life out of water. So, how did they do it?

Canada's migratory caribou are under threat. Will we act before it's too late?

Delegates are gathering in Campo Grande, Brazil, for the 15th Conference of the Parties (COP15) on the Convention on the Conservation of Migratory Species of Wild Animals. The meeting aims to address growing threats to migratory ...

CHEOPS discovery defies planetary formation rules

We're starting to see just how exceptional our own solar system and its history is, as more exoplanets are discovered. A fourth exoplanet discovery in the LHS 1903 system made by ESA's CHEOPS mission places a rocky world ...

This isn't just another rocky world orbiting a red dwarf—this one's special

Astronomers have found an exoplanet that could serve as a benchmark in future studies. It's a rocky planet orbiting an M-type star, and though these planets are plentiful, this one could serve as a benchmark for understanding ...

NASA's tiny spacecraft sends first exoplanet images

With the first images from the spacecraft now in hand, the team behind NASA's Star-Planet Activity Research CubeSat, or SPARCS, is ready to begin charting the energetic lives of the galaxy's most common stars to help answer ...

A new model defines an upper limit to planetary radiation belt intensity

We all know that stars radiate light and much more. But radiation belts can also surround many other celestial bodies, such as planets. These belts do not generate particles themselves—the belts receive them from nearby stars—but ...

Would Earth still be habitable without us?

Here's a thought experiment that keeps planetary scientists awake at night. Strip every living thing from our planet, every bacterium, every blade of grass, every creature that has ever drawn breath and ask a simple but profound ...

Football-sized fossil creature may have been one of the first land animals to eat plants

Life on Earth started in the oceans. Sometime around 475 million years ago, plants began making their way from the water onto the land, and it took another 100 million years for the first animals with backbones to join them. ...

Some tropical land may heat up nearly twice as much as oceans under climate change, sediment record suggests

Some tropical land regions may warm more dramatically than previously predicted, as climate change progresses, according to a new CU Boulder study that looks millions of years into Earth's past. Using lake sediments from ...

Webb finds young sun-like star forging common crystals and flinging them into its outer disk

Astronomers have long sought evidence to explain why comets at the outskirts of our own solar system contain crystalline silicates, since crystals require intense heat to form and these "dirty snowballs" spend most of their ...
