June 24 Rosetta Images! by:

Rosetta spacecraft image archive complete  Rosetta journeyed through space for 12 years and performed early flybys of Earth, Mars and 2 asteroids before arriving at comet 67P/Churyumov-Gerasimenko. It produced nearly 100,000 images. Some of the best, here. Tonight … Moon to the west of Jupiter Sunday night's moon is near the head of Scorpius. The little arc of 3 stars here is sometimes called the Crown of the Scorpion. Why do fireflies light up? A firefly's familiar glow is caused by a chemical reaction. Explanation here, plus many wonderful firefly photos. Will climate change make rice less nutritious? As atmospheric carbon dioxide levels rise, rice plants - the primary food source for more than 3 billion people - produce fewer vitamins and other key nutrients.

The perfect swarm Eileen Claffey calls this image The Perfect Swarm. She said it's "... 44 stacked images of the mating cycle of fireflies. Humid, wet, and warm." Thanks, Eileen!

Tonight … Moon to the west of Jupiter It's rare when star patterns on our sky's dome have anything to do with real associations of stars in space, but the 3 stars near tonight's moon - known as the Crown of the Scorpion - are thought to be loosely bound by gravity. All 3 are located at approximately the same distance, about 500 light-years away. They're members of the Scorpius-Centaurus group, which was first recognized by astronomers in the early part of the 20th century. Submit your photo to EarthSky here!
