evosiaLunar Eclipse timelapse with a telescope!
Orb
Astronaut Jack Fischer took this photo of the moon with the barest hint of the top of Earth’s atmosphere in the frame from the window of the International Space Station on July 7. This shot of the nearly full moon was taken only a short time after the conclusion of a partial lunar eclipse. This is the last full moon before the upcoming total solar eclipse, which will take place on the next New Moon.
The rayed crater you see in the right side of the frame is known as Tycho. The dark areas are known as Mare – a term that dates back before telescopes when these areas were thought to be possible seas. We now know they are mostly impact craters that have since filled with lava. At the far left side of the frame there are 2 large mare that show up well in this shot: Mare Imbrium is the lower one and Mare Serinatatis is above it. The next dark spot up and to the right, with more poorly defined boundaries than the sharp edges of Serinatatis, is Mare Tranquilatatis or the Sea of Tranquility; site of the first human footprints on the Moon.

We should be just about to a new moon right now, after a full moon 2 weeks ago. Here’s a timelapse, high zoomed video of the Full Moon rising at Perigee two weeks ago.Check out the detail you can see when zoomed in.
I believe this video missed the penumbral lunar eclipse, but the full moon views this week were spectacular for me, so here’s another.

Just holding various pieces of the moon nbd
NASA prepared some of these disks containing the basic ingredients found on the moon out of the rocks brought back by Apollo. The Anorthosite is a plagioclase-rich crust that formed from minerals that floated in the lunar magma ocean. The basalt is igneous rock erupted later. The breccias are fractionated by later impacts. The orange soil is volcanic glass erupted as part of one of these later eruptive sequences. The final ones are lunar regolith - broken up particles that coat the surface.

The Messel pit (see http://on.fb.me/1VRgpkr) is a delight to all palaeontologists who study the Eocene era, especially those interested in the evolution of mammals, due to its excellent preservation. The mare died shortly before giving birth, possibly as she was taking a drink when the lake released a dose of poisonous ground hugging carbon dioxide. As with many specimens from this site, many soft tissues including the placenta were preserved as 'bacterial photographs', where the microorganisms aligned with the tissues of the dead animal and were replaced by particles of mud. It is the earliest and best preserved mammalian foetus found to date, and the mare's reproductive system was very similar to that of a modern equid.
