The universe lived through a prolonged "Dark Ages" until hydrogen reionized.
Now, researchers are closer to figuring out when that happened.

Manganese deposits in Gale Crater fractures are similar to Earth features that usually require flowing water and highly oxidizing conditions.

China's lunar-based telescope observes a binary star system
http://phys.org/news/2016-08-china-lunar-based-telescope-binary-star.html
China's Chang'e-3 mission landed on the moon in December 2013 and deployed a lunar rover known as Yutu or Jade Rabbit;
it also carried a robotic telescope designed to observe various celestial objects such as galaxies, active galactic nuclei,
variable stars, binaries, novae, quasars and blazars in the near-ultraviolet band. The Lunar-based Ultraviolet Telescope
(LUT) was recently used by a team of Chinese astronomers to observe a peculiar binary star designated V921 Her. Results of
these observations are described in a paper published Aug. 1 on arXiv.org.

This galaxy, known as NGC 2337, resides 25 million light-years away in the constellation of Lynx. NGC 2337 is an irregular galaxy,
meaning that it — along with a quarter of all galaxies in the Universe — lacks a distinct, regular appearance. The galaxy was discovered
in 1877 by the French astronomer Édouard Stephan who, in the same year, discovered the galactic group Stephan’s Quintet (heic0910i).

HOWKING: právě to mě zajímá, nakolik je ta křivka správná. Budu pozorovat i z pátku na sobotu, ale čtvrteční noc údajně nejlepší.
HOCH2: Dík za info.

VIRGO: Neco podobneho znam - Mam doma knizku Sest dnu na Lune, kde je popisovan tyden pobytu malych pionyru na mesici. Je tam plno propagandy a techto vizi budocnosti ve vesmiru. Velmi doporucuji pro to, abyste si udelali obrazek te doby.

VIRGO: Byl jsem dne s v noci v Beskydech a řekl bych, že 10 m/h už se konalo. Tak pokud je ta křivka dobře, mohlo by to být i "podhajpováno" :-)

Breaking News for sky aficionados: The Perseids of 2016 ... beyond the hype

HOWKING: Jsem zvědavý! Dnešní debaty lidí kolem výzkumu meziplanetární hmoty
nebyly zdaleka tak optimistické. Pův. předpoklad (200m/h) je údajně velice přehajpovaný, tak uvidíme.
Čtvrteční noc už mám červeně označenou (pokud bude přát počasí - podle dnešní předběžné předpovědi
dobrý), tak uvidíme.

Universität Würzburg: Possible Extragalactic Source of High-Energy Neutrinos

Coincidence of a highly energetic outburst of an active galactic nucleus with a neutrino event at PeV energy

Nearly 10 billion years ago in a galaxy known as PKS B1424-418, a dramatic explosion occurred. Light from this blast began arriving at Earth in 2012.
Now, an international team of astronomers, led by Prof. Matthias Kadler, professor for astrophysics at the university of Würzburg, and including other
scientists from the new research cluster for astronomy and astroparticle physics at the universities of Würzburg and Erlangen-Nürnberg, have shown that
a record-breaking neutrino seen around the same time likely was born in the same event. The results are published in "Nature Physics".

VIRGO:
Huh...Každý výstup RT je pro mně celovečerní film, dnes to byl rovnou film týdne, pač pod článkem
se rozjela debata s věčným kosmoantagonistou Chrisem Reevesem. Pro mně jakožto laika těžký oříšek,
ale vlastně i proto ty Taylorovy simulace miluju. Vždycky nákop a poznávání nového, případně starší
věci zapadají do souvislostí.

Celkem dlouho jsem přemýšlel, jestli sem hodit i onu debatu pod článkem. Nakonec jsem to nechal být,
protože je cca 5x obsáhlejší než text samotný. Takže kdyby to někoho zajímalo, napište mi do pošty,
a já to rád přepošlu.
