News | Test for Damp Ground at Mars' Seasonal Streaks Finds None
http://www.jpl.nasa.gov/news/news.php?release=2016-215&rn=news.xml&rst=6597
Seasonal dark streaks on Mars that have become one of the hottest topics in interplanetary research don't hold much water,
according to the latest findings from a NASA spacecraft orbiting Mars.

The new results from NASA's Mars Odyssey mission rely on ground temperature, measured by infrared imaging using the spacecraft's Thermal Emission Imaging System (THEMIS).
They do not contradict last year's identification of hydrated salt at these flows, which since their 2011 discovery have been regarded as possible markers for the presence
of liquid water on modern Mars. However, the temperature measurements now identify an upper limit on how much water is present at these darkened streaks: about as much as
in the driest desert sands on Earth.

VIRGO: mno, na Europě (a možná i na Ganymedu - o tom se mluví méně, ale oceán tam může být taky) by mohl být život víceméně pozemského typu (toho hlubokomořského, ne fotosyntetizující). Na Enceladu by to asi byla výrazně větší exotika a na Titan už se předpokládá biochemie zcela nepodobná té na Zemi (a museli bychom pak zásadně přehodnotit naše představy o obyvatelnách zónach u exoplanet i "exoměsíců")

Just how dangerous is it to travel at 20% the speed of light?
Breakthrough Starshot has examined the impact of stray atoms, cosmic dust.

The space between here and the nearest star isn't completely empty. Earlier generations of stars have left a sparse collection of tiny dust particles,
and various processes have left individual atoms scattered through the interstellar space. These particles pose very distinct risks, and the team worked
through each separately.

The main problem with running into an atom isn't the physical collision but rather the energy deposited in the spacecraft by the impact, which can cause
local heating that damages the craft in two ways. When high enough, the heating causes the material the craft is made of to evaporate into space. Below
that threshold, it can cause local melting, leading to a change in material properties as the area resolidifies.

Globular clusters and halo assembly

Hierarchical accretion models for galaxy formation predict that the majority of stars in the halo of a spiral galaxy
should have formed within dwarf galaxies that were later accreted by the larger galaxy. In 2010, we used a rough chemical
tagging approach to identify stars in the Milky Way halo that had likely formed in globular clusters, using the light-element
abundance anomalies that are well-studied in Galactic globular clusters.

Fossilized rivers suggest warm, wet ancient Mars
http://phys.org/news/2016-08-fossilized-rivers-ancient-mars.html
Extensive systems of fossilised riverbeds have been discovered on an ancient region of the Martian surface, supporting the idea
that the now cold and dry Red Planet had a warm and wet climate about 4 billion years ago, according to UCL-led research.
The study, published in Geology and funded by the Science & Technology Facilities Council and the UK Space Agency, identified over
17,000km of former river channels on a northern plain called Arabia Terra, providing further evidence of water once flowing on Mars.

XCHAOS: Nejen magnetosféra, ale i slapová působení mateřské planety.
Rovněž vzdálenost celého systému od mat. hvězdy musíme brát v potaz.
Mně místo Star Wars odkojila maková panenka, ale v tomto ohledu jsou obě ságy stejně relevantní. :)

On už výraz "obyvatelnost" je všeobsažný. Jaké formy by to měly obývat? Primitivní organismy?
Křemíková inteligence? Jak pak definujeme, co je živé? Zatím se nám to všechno točí vesměs
kolem biologie. V obou zmíněných případech by hypoteticky ten Titan mohl klapnout. Ale biodiverzita
v pozemském smyslu? To zcela určitě ne. Je to těžké - ale nesmírně zajímavé.

Už to tu padlo víckrát: Potřebujeme víc přesnějších dat sledování co nejvíce exosystémů,
což se nám snad v příštích 15 letech podaří

k předchozímu - tak jako prý jo...

kritický faktor je asi magnetosféra planety, kolem které takový měsíc obíhá

VIRGO: taky často přemýšlím, při všech těch zprávách o objevech exoplanet, že třeba kolem složením a gravitací neobyvatelných planet v obyvatelné zóně by přece mohly obíhat obyvatelné měsíce :-) (a dokonce by se třeba mohlo ukázat, že nejtypičtějším osídleným tělesem jsou měsíce, a ne planety...). (dobře, tohle je asi trochu ovlivněné Star Wars a měsícem Endor :-)

Je pravda, že v naší soustavě Titan coby měsíc, který si drží atmosféru, je spíš vyjímka, ale co vlastně brání tomu, aby planeta velikosti Jupitera měla měsíc velikosti např. Země?
