Star Sprawl

Unlike most galaxies, which resemble ellipticals or spirals, this galaxy does not conform to a clear shape. About a quarter of star systems take a similarly indefinite form and are known as irregular galaxies, according to NASA.

Physics of Sphere Skipping

Photographing balls bouncing across water with high speed cameras revealed some secrets of why they travel so well. Researchers at Utah State University found that elastic spheres deform into disk shapes to skip along water’s surface.

Tiny Tot

A video of an elephant and a baby in Kruger National Park in South Africa posted by Kruger Sightings shows the two crossing the road together, before the adult elephant appears to pull the youngster away from onlooking humans with her trunk.

Black Hole Shoots Jet

The Pictor A galaxy contains a supermassive black hole at its center and produces a giant jet of particles streaming at nearly the speed of light over a distance of 300,000 light years, according to NASA.

Super Guppy

NASA’s unusual looking aircraft known as the Super Guppy transported spaceship parts around the country.

Hand of God

Photographer and weather blogger Rogerio Pacheco shared photos of this “Hand of God” cloud, seen from the Portuguese island of Madeira. According to a BBC weather meteorologist, the cloud’s fiery appearance is the serendipitous result of good morning light.

Rebel Galaxy

The spiral-shaped galaxy LO95 0313-192 is unusual for its jets of particles shooting from its center, which normally occur at the cores of elliptical galaxies or merging galaxies. The star system is roughly one billion light years away, according to NASA
