A photo of astronauts Scott and Mark Kelly

Astronaut Scott Kelly (left) spent a year in space on the International Space Station while his identical twin brother, astronaut Mark Kelly (right), remained on Earth. They were part of a landmark study to help researchers understand how space flight affects the human body.

Some interplanetary dust grains that end up in Earth’s atmosphere may have traveled long distances. They may hail from the Kuiper Belt (illustrated). It is a region of icy objects out beyond Neptune that orbit the sun.

Space dust rains down on Earth all the time. Most of these specks are too small to see. But when one the size of a sand grain hits the atmosphere, it blazes with visible light, becoming a micrometeor, or “shooting star.”

an image of the moon and where the impact happened

During a lunar eclipse on January 21, amateur astronomers caught lucky views of an object roughly the size of a basketball smacking into the moon and producing a bright flash of light (inset).
