This is quite bizarre and has not yet been fully explained:
X-ray Detection Sheds New Light on Pluto. Scientists using NASA’s Chandra X-ray Observatory have made the first detections of X-rays from Pluto. These observations offer new insight into the space environment surrounding the largest and best-known object in the solar system’s outermost regions. |

SpaceX have given some more details on how and why they plan to put 100 people on Mars in 2025. First link is a 90 minute talk (with embarrassing Q&A), second is a written interpretation (with bad language):
https://www.youtube.com/watch?v=IAZ-Xbn5hr0. http://waitbutwhy.com/2016/09/spacex...ull-story.html. There is a lot more about it elsewhere online. I'm a bit surprised to be the first to mention it here. It's based around a big rocket, and it seems clear that can do a lot more than Mars. |

Had to smile at Jeremy Paxman's little slipup in University Challenge last night. In reply to a contestant who wrongly thought that Sirius might be in Ursa Minor (The Little Bear) he informed him that it was in the Great Bear (Ursa Major instead of Canis Major - The Great Dog).

^ That is an excellent video and the universe has indeed just got much larger:More than a trillion galaxies are lurking in the depths of space, a new census of galaxies in the observable universe has found — 10 times more galaxies than were previously thought to exist. |

The space section of Phys.org is always updated, very, very quickly.
http://phys.org/space-news/ Excellent articles from National Geographic. http://news.nationalgeographic.com/2...space-science/ http://news.nationalgeographic.com/2...space-science/ It's such a shame people have put years and years of their lives into the Schiaparelli lander and now that has all gone - they must be utterly heartbroken.

Schiaparelli spotted
NASA’s Mars Reconnaissance Orbiter has identified new markings on the surface of the Red Planet that are believed to be related to ESA’s ExoMars Schiaparelli entry, descent and landing technology demonstrator module.
Schiaparelli entered the martian atmosphere at 14:42 GMT on 19 October for its 6-minute descent to the surface, but contact was lost shortly before expected touchdown. Data recorded by its mothership, the Trace Gas Orbiter, are currently being analysed to understand what happened during the descent sequence. http://www.esa.int/Our_Activities/Sp...i_landing_site |

Well they certainly demonstrated that technology. Mission accomplished. Now back to the drawing board.

They must be gutted all that time and effort to fail on the final part.
At least with the latest images and the Data it sent back they can maybe learn lessons from it |

The biggest 'Supermoon' for 68 years.

Hot off the presses from the Jet Propulsion Laboratory (and it is good news):
Mars Ice Deposit Holds as Much Water as Lake Superior Frozen beneath a region of cracked and pitted plains on Mars lies about as much water as what's in Lake Superior, largest of the Great Lakes, researchers using NASA's Mars Reconnaissance Orbiter have determined. Scientists examined part of Mars' Utopia Planitia region, in the mid-northern latitudes, with the orbiter's ground-penetrating Shallow Radar (SHARAD) instrument. |

Isn't it a bit American though? I only tend to like BBC Horizon etc 40 x 50mins? What about the Director's Cut Box Set. at 7 days? Or 6500 years? True afficionados go for the full 13.7 billion years on Youtube |

Yeah, I like Kaku-sensei, mostly
Actually, my main gripe against documentaries and presenters is when they dumb-down. I know there are commercial and educational and target-audience reasons for this Still, annoying when you are looking forward to a decent documentary and Brian Cox (or Michio Kaku) opens the programme with... "This is our Sun <points at sky>. It is big and yellow and keeps us warm and the crops growing" |

Michio Kaku, on one of those documentaries, said that if all of the stars in the Milky Way were peas there would be enough to fill a stadium. No mention of pea variety or which stadium!
Just say, "somewhere between one hundred million and four hundred million stars", and don't patronise me by telling me how may zeroes that is.

You can get 500 million Petit-Pois into Ibrox apparently (not deep-fried)
