Volcanoes Erupted 'Recently' on the Moon
NASA’s Lunar Reconnaissance Orbiter (LRO) has provided researchers strong evidence the moon’s volcanic activity slowed gradually instead of stopping abruptly a billion years ago. Scores of distinctive rock deposits observed by LRO are estimated to be less than 100 million years old. This time period corresponds to Earth’s Cretaceous period, the heyday of dinosaurs. Some areas may be less than 50 million years old. Details of the study are published online in Sunday’s edition of Nature Geoscience. http://www.nasa.gov/press/2014/octob.../#.VDxNw0t3uxo http://news.discovery.com/space/imps...oon-141014.htm http://www.nature.com/ngeo/journal/v.../ngeo2252.html http://www.readcube.com/articles/10....how_checkout=1 Certainly, there was vulcanism on the Moon in the past and we can see that in the lunar cinder cones http://blogs.discovermagazine.com/ba...es-300x270.jpg and in the orange lunar soil http://earthsky.org/space/this-date-...th-orange-soil but that was billions of years ago unlike this relatively recent discovery. 'Strikingly Geometric' Shapes Hidden on Moon's Surface A massive feature on the moon formed due to lunar rifts, in a surprise revision to earlier theories, research shows. Previously, scientists thought the moon's Ocean of Storms was a round crater left after a giant impact, but now researchers have found it is underlain by a giant rectangle created by cooling lunar lava as the moon formed. This finding reveals the early moon was far more dynamic than previously thought, scientists added. http://www.space.com/27308-moon-ocea...rectangle.html |

Where I live now, I have just seen the full Moon rise over the mountains. To say I was impressed would be a understatement.
This was a naked eye observation, just looking out on the balcony by chance.

I have seen the first picture of Pluto.
New Horizons getting closer. Only about 8 months to go. |

Whoosh! It only seems yesterday that they blasted the thing off. What a trip!
It may longer be classified as a planet but for decades was seen as the outermost sentinel of the Solar System (of course it is anything but when compared to other Kuiper belt objects and the Oort Cloud) but I have always wanted to know what Pluto and Charon actually look like from close range .

I'm going to guess at a rock strewn stony desert landscape. I hope one of the moons throws up something totally unexpected.

The Philae lander will be deployed around breakfast time Wednesday. Doubts are being expressed about whether the landing will be success given the terrain and accuracy of landing: https://www.youtube.com/watch?v=uI7D7FGh7cY
ESA will know around 4pm GMT if it reached Site J intact: https://twitter.com/ESA_Rosetta |

There'll also be a live feature on Slooh: http://live.slooh.com/
New Scientist are running a live blog tomorrow: http://bit.ly/rosettaliveblog First pictures from Philae hopefully available at 6pm tomorrow. |

Its still Americas greatest acheivement.... landing men on the moon.... getting a moon buggy up there ... back in the 60s and early 70s
A total of twelve men have landed on the Moon. This was accomplished with two US pilot-astronauts flying a Lunar Module on each of six NASA missions across a 41-month time span starting on 20 July 1969 with Neil Armstrong and Buzz Aldrin on Apollo 11, ending on 14 December 1972 with Gene Cernan and Jack Schmitt on Apollo 17. Cernan was the last to step off the lunar surface. We landed a total of 6 times on the moon.... but that was all 40 plus years ago !!! Is nt it time for a new moon mission ? not a manned mission...... but put a robot buggy up there with the ability to travel long distances... send back fabulous HD video and give us a tour of the moon with fantastic, sharp , colour pictures. The mission can be built up in the media... the launch televised .... does nt take long to get to the moon... video of the receding earth and the upcoming moon Lets rekindle the publics interest in space flight once again.... lets get it together for a Sept 2015 launch (if Barack gets behind it .... a successful mission could boost his ratings in the polls.) |

here it is, people.
Comets. Comets are not old. They are young. They are not the source of life. Read "Worlds In Collision", people. "They" will keep this knowledge from you. Glad I could help. |

Watching on BBC News, and they are reporting that the probe has landed.

I really don't know why we need all of these experts on TV when you are around. Close down NASA and ESA. You have all of the answers.

Good job scientists are calm, collected & introverted as after the landing celebrations I wouldn't want to meet an extrovert one

That's crackpot Velikovsky nonsense you've mentioned before. Nobody sensible believes it.

Seems lander bounced and landed a second time, hope it doesn't float off. Fingers crossed.

The subject of why so many comets look like huge peanuts was discussed too: https://cumbriansky.files.wordpress....0-020_2014.jpg Quote:
"The fundamental criticism against this book from the astronomy community was that its celestial mechanics were irreconcilable with Newtonian celestial mechanics, requiring planetary orbits which could not be made to conform to the laws of conservation of energy and conservation of angular momentum (Bauer 1984:70). Velikovsky conceded that the behavior of the planets in his theories is not consistent with Newton's laws of motion and universal gravitation. He proposed that electromagnetic forces could be the cause of the movement of the planets, although such forces between astronomical bodies are essentially zero"

New Horizons Update Preparations are starting for the Pluto encounter next summer, its now 2.9 Billion Miles from earth and just 162 Million miles from Pluto. Quote:
New Horizons spacecraft comes out of hibernation for the last time on Dec. 6. Between now and then, while the Pluto-bound probe enjoys three more weeks of electronic slumber, work on Earth is well under way to prepare the spacecraft for a six-month encounter with the dwarf planet that begins in January
