The only known life in the universe lives on a mid-size rocky planet that orbits a mid-size yellow star. That makes our planet a bit unusual. While small rocky planets are common in the galaxy, yellow stars are not. Small red dwarf stars are much more typical, making up about 75% of the stars in the Milky Way. This is why most of the potentially habitable exoplanets we’ve discovered orbit red dwarfs.

Light Pollution is Making it Harder for Animals to Find Their Way at Night
Ah, the majestic dung beetle. The pinnacle of evolution. In all seriousness, these little critters are incredibly sophisticated navigators who have, for millennia, used the night sky to guide them about their business. But light pollution is making their lives more difficult by limiting their ability to navigate by the stars. Other nocturnal creatures, including some birds and moths, may be facing similar challenges.

Animals Could Have Been Around Hundreds of Millions of Years Earlier Than Previously Believed
According to the most widely accepted theories, evolutionary biologists assert that life on Earth began roughly 4 billion years ago, beginning with single-celled bacteria and gradually giving way to more complex organisms. According to this same evolutionary timetable, the first complex organisms emerged during the Neoproterozoic era (ca. 800 million years ago), which took the form of fungi, algae, cyanobacteria, and sponges.

Russia’s new Module Kicks the Station out of Position, Causes a Delay for Starliner
On July 28th, the International Space Station (ISS) suffered a mishap after a new Russian module (named Nauka) fired its thrusters just hours after arriving. As a result, the entire station was temporarily pushed out of position, forcibly delaying the Orbital Flight Test-2 (OFT-2) mission. This would have been Boeing’s CT-100 Starliner second attempt to rendezvous with the ISS as part of NASA’s Commercial Crew Program (CCP).
