Unlike most spacecraft, which are powered by rocket engines and cost hundreds of millions of dollars, these tiny satellites are expected to cost a few million dollars each and use the sun’s energy to push them across a windless space.
A newly discovered fossil from Changyuraptor yangi, a species of “four-winged” flying dinosaur, reveals a design more like a plane than a bird, according to a team of scientists. Science reporter Amina Khan explains how its extra-long tail feathers could have helped it to get around despite its comparatively large size.

Scientists have discovered the fossilized remains of a 2-inch-long hedgehog that lived 52 million years ago. They named it Silvacola acares, which means “tiny forest dweller.” The team also found fossils from a tapir-like animal at the same site.

In August, Lego will produce a limited-edition set called Research Institute, featuring three female scientists — an astronomer, a paleontologist and a chemist. The set was designed by Ellen Kooijman, a geochemist at the Swedish Museum of Natural History.

Tiny swimming robots inspired by sperm could one day be used in surgical procedures, scientists say in a new report.
NASA’s Interface Region Imaging Spectrograph (IRIS) has captured video of a coronal mass ejection — solar material shooting out of the sun — in unprecedented detail.
With IRIS, scientists are trying to get to the bottom of what is known as “the solar corona mystery” (a phrase that a cursory Google search suggests is not yet a band name, if you were wondering).
