Galaxies collide, the Milky Way sparkles, and a forest fire rages in this week's best space pictures.">
A cosmic crash scene of two galaxies, with many young star clusters strewn about, is on display in this new near-infrared image by the Gemini South Observatory in Chile.
Sitting 10.5 million light-years from Earth, the two intertwining islands of stars are known as the antennae galaxies due to the two, spindly arms coming out from the galactic core that look similar to insect antenna.
These antenna-like structures—made of millions of stars—were originally spiral arms, a normal part of a galaxy. Over time they became gravitationally distorted and drawn out into space during the initial collision between the galaxies 300 million years ago.
The delta of the southern Egyptian river Khor Baraka—more than 340 miles (550 kilometers) below the ISS—is a large area filled with loose sand and clay that gets routinely kicked up by strong winds channeled into the area by nearby hills.
