Bioinspired material mimics squid beak

(Phys.org) —Researchers led by scientists at Case Western Reserve University have turned to an unlikely model to make medical devices safer and more comfortable—a squid's beak.

Mysterious hot spots observed in a cool red supergiant

(Phys.org) —Astronomers have released a new image of the outer atmosphere of Betelgeuse – one of the nearest red supergiants to Earth – revealing the detailed structure of the matter being thrown off the star.

The moving Martian bow shock

As the energetic particles of the solar wind speed across interplanetary space, their motion is modified by objects in their path. A study, based on data from ESA's Mars Express orbiter, has thrown new light on a surprising ...

The bow shock of Kappa Cassiopeiae, a massive, hot supergiant

(Phys.org) —Roguish runaway stars can have a big impact on their surroundings as they plunge through the Milky Way galaxy. Their high-speed encounters shock the galaxy, creating arcs, as seen in this newly released image ...

Three NASA satellites recreate solar eruption in 3-D

The more solar observatories, the merrier: Scientists have developed new models to see how shocks associated with coronal mass ejections, or CMEs, propagate from the Sun—an effort made possible only by combining data from ...
