When Did Insects Evolve?

Our planet is dominated by insects, and when and how insects took over the earth is a question that’s puzzled naturalists for centuries. In an incredible international effort, 100 scientists combined their molecular, computational biology, statistics, paleontology, and taxonomic expertise to uncover some surprising conclusions about when major groups of insects evolved.

Birth of Planets Captured in Astonishing Photos

Astronomers have captured the best image ever of planet formation around an infant star. This revolutionary new image reveals in astonishing detail the planet-forming disk surrounding HL Tau, a Sun-like star located approximately 450 light-years from Earth in the constellation Taurus, including multiple concentric rings separated by clearly defined gaps. These structures suggest that planet formation is already well underway around this remarkably young star.

First Amphibious "Sea Monster" Found; Fills Evolutionary Gap

The ichthyosaur fills a crucial gap in the evolution of these dolphin-like predators, which thrived in Jurassic seas about 200 million to 145 million years ago. Scientists knew these reptiles evolved from land to the sea, since they have found fossils of both land-dwelling ancestors and the fast-swimming marine creatures, so paleontologists suspected there must be some in-between ichthyosaurs out there.

Where'd You Get That Great Idea? Team Seeks the Source of Creativity: Near or Far?

Why Our Galaxy's Black Hole Didn't Eat Mystery Object

In 2011, astronomers were excited to discover a large cloud of gas careening toward the supermassive black hole that resides in the center of the Milky Way. But earlier this year, astronomers discovered that far from being eaten by the black hole the cloud of gas carried on its merry way, orbiting past the gravitational behemoth.
