Astronomers are puzzled by a strange bright spot which has appeared in the clouds of Venus.
The spot was first identified by an amateur astronomer on 19 July and was later confirmed by the European Space Agency's Venus Express spacecraft.
"One transport truck-sized asteroid passed the Earth Wednesday morning and another will soar by in the afternoon, with both far closer to the planet than the moon.
There is no danger of the Earth being hit and both should be visible with moderate-sized amateur telescopes, NASA reported."
"Greetings citizen scientists, budding biohackers, and backyard explorers! We think you'll find the Make: Science Room a fun and useful resource. We hope you'll use it as your DIY science classroom, virtual laboratory, and a place to share your projects, hacks, and laboratory tips with other amateur scientists. Your Make: Science Room host is Robert Bruce Thompson, author of Illustrated Guide to Home Chemistry Experiments: All Lab, No Lecture. (Make: Books, 2008) and Illustrated Guide to Forensics Investigations: Uncover Evidence in Your Home, Lab, or Basement (not yet published). We'll be drawing material from these titles first, but will soon branch out into biology, astrononmy, Earth sciences, and other disciplines."
