Space Pictures This Week: Meteor Smoke, Mars Canyon, More

Bloom of Youth

What NASA calls a "beautiful young crater" sits within the moon's complex crater Icarus in a picture released October 23 by the team behind the Lunar Reconnaissance Orbiter.

Freshly kicked up by the impact that created the crater, subsurface material shines bright against long-exposed rocks. But the bright, dandelion-like blast site should fade to match the surrounding ground relatively soon, by lunar standards—within hundreds of millions of years.

Full of Stars

Image by Louie Atalasidis, My Shot

Star stalker Louie Atalasidis captured a stellar feature of the constellation Orion the Hunter from Bankstown, Australia—the Orion Nebula, a star-forming cloud of gas and dust.

The nebula—seen in a picture Atalasidis shared with National Geographic's My Shot photography community on October 26—is about 1,500 light-years away. Even so, the space cloud can be seen with the naked eye under dark skies as part of the "sword" hanging from Orion's belt in the iconic constellation. (Get Orion Nebula wallpaper.)

Smoke on the Water, Fire in the Sky

Photographs by Babak Tafreshi, TWAN

Seen in several photos taken over a half hour, smoke from an Orionid fireball squiggles across the sky over a pond in northern Maine on October 19.

The Orionid meteor shower is caused when Earth slams into a debris field left behind by Halley's comet, which won't return to our neck of the woods for another five decades. (Find out why Halley's comet has been seen as an omen of doom.)

Magnetic Appeal

Art and science melt and merge in a new picture of the sun created October 19 at NASA's Goddard Space Flight Center in Greenbelt, Maryland. Scientists used a gradient filter—often used by photo editors to create dramatic effects.

By boosting contrast in the image, the gradient filter better reveals coronal loops, arcs of solar material whose paths are determined by magnetic fields in the sun's atmosphere. Studying those field lines, according to Goddard, "can help researchers understand what's happening with the sun's complex magnetic fields, fields that can also power great eruptions on the sun, such as solar flares or coronal mass ejections."

Starry Night

Stars seem to pinwheel above a stone house in the Himalayan region of Garhwal, India, on October 20. Shared with National Geographic's My Shot photography community the next day, the image was captured with the light of the full moon—and a very long exposure.
