The Venus and Mars conjunction in the evening sky will be best around July 12 or July 13. The young moon will join them in the western twilight sky.

A new study from scientists at LMU in Germany says that there could be enough heat and liquid water on moons of rogue planets - free-floating worlds with no suns - to support life. Cosmic rays could drive processes such as photosynthesis, instead of direct sunlight.

The sun passes in front of Ophiuchus each year from about November 30 to December 18.

An evolutionary biologist explains how snakes use their tongues to collect and transport molecules to vomeronasal organs in their mouths, not to taste them, but to smell them.

A new study from researchers at the University of Naples in Italy suggests that highly-evolved, Earth-like biospheres may be rare on exoplanets. Many stars either don't emit enough energy for life to develop past the basic photosynthesis stage or don't live long enough for life to evolve on any planets that may otherwise be suitable.

NASA's Mission Equity virtual public meeting on July 13, with the goal of including underrepresented and underserved communities.
