It’s time for the most intense nights of Perseid meteor shower (August 10–13; Tuesday night with as many as 100 ‘shooting stars’ per hour), here are some tips:
Give your eyes 20 minutes to adjust to the dark. Avoid looking at the moon, your phone or any device that shows light – any exposure to bright lights will instantly ruin your eye’s acclimatization to the dark
If possible go outside the city, or search for good local stargazing places
For the best chances of spotting a shooting star, scan the whole sky repeatedly
Be prepared to spend a few hours sitting outside. Meteor showers can be seen as soon as it gets dark, but better viewing begins about 11 pm
If you have binoculars or a telescope, take them with you. While you’re there, you can also look for constellations, stars, and planets
All around the world, oceans glow and trees sparkle because of Bioluminescence, the production of light by living organisms.
Bioluminescent creatures have a chemical reaction in their body that creates light. The chemical Luciferin (a substrate) reacts with Luciferase (an enzyme) to create a by-product called Oxyluciferin. or as we see it; Light.

This is a comet named 67P/Churyumov-Gerasimenko. A satellite called Rosetta rendezvoused with it today, Aug. 6, after traveling 4 billion miles for more than 10 years.
The European Space Agency craft now sits 62 miles from the icy 2.5-mile-long comet (see a visualization of the mission here) about midway between Mars and Jupiter. The two will travel together on the comet’s orbit as it approaches the sun.
Rosetta, which also includes a number of NASA instruments, will for the first time in history study a comet up close, put a lander on the surface and monitor changes as it approaches the sun. Among other science to be done, the craft’s Philae lander will drill almost 8 inches into 67P, another first.
On behalf of the citizens of Earth, congratulations NASA, ESA, and everyone outside of these organizations responsible for the successful construction, launch, deployment, 10 year navigation, and implementation into orbit/rendezvous with comet 67P/Churyumov-Gerasimenko!!!
