» Life Under a Black Sun
http://sciworthy.com/science-news/life-under-a-black-sun/
Every living thing on our Earth has to thank the Sun for its ability to survive, as it warms the Earth to liveable temperatures.
It is hard for us to imagine how a civilization could function without a star shining bright in the sky of its host planet.

Scientists in the Czech Republic have been researching if a planet could harness enough energy to run a civilization if the planet
were orbiting a black hole instead of a star. This would work in a fundamentally different way than how our planet and civilization
work. The sun emits light and UV-radiation, the type of sunshine that causes a sunburn. This light and radiation carry energy that
gets used by things like plants and solar panels. Black holes don’t produce light1, hence the name black holes, but they have mind-
boggling amounts of gravity, enough to attract light and radiation.

Do Intelligent Civilizations Across the Galaxies Self Destruct? For Better and Worse, We’re The Test Case – Many Worlds
http://www.manyworlds.space/...s-the-galaxies-self-destruct-for-better-and-worse-were-the-test-case/

If there are billions of exoplanets out there — as speculated back then but proven now — why have there been no bona fide reports of advanced extraterrestrials
visiting Earth, or perhaps leaving behind their handiwork?

Many answers have been offered in the following decades — that we are alone in the universe, that the distances between solar systems are too great to travel,
that Earth became home to life early in the galaxy’s history and other planets are only now catching up, that life might be common in the universe but intelligent
life is not. I would like to focus on another response, however, one that came to mind often while reading a new book by the former holder of the astrobiology
chair at the Library of Congress, planetary scientist David Grinspoon.

This potential explanation is among the most unsettling: that intelligent and technologically advanced beings are likely to ultimately destroy themselves. Along
with the creativity, the prowess and the gumption, intelligence brings with it an inherent instinct for unsustainable expansion and unintentional self destruction.

Proxima Centauri: The Problem of Arrival
http://www.centauri-dreams.org/?p=37063

Given his key role in the development of sail ideas for interstellar flight, Robert Forward inevitably comes up in any discussion
of deep space missions. The late physicist put forward a number of sail concepts and mission ideas, including a laser-driven lightsail
to Epsilon Eridani with return capability that would travel at 50 percent of the speed of light. Those were numbers that made a manned
mission theoretically possible, though demanding a huge sail (1000 kilometers in diameter) and a mind-bending space-based 75,000 TW
laser system.

Yesterday we looked at the critical problem of deceleration in a sail-based interstellar mission, with reference to the new paper by
René Heller and Michael Hippke. I only wish Forward were here to give us his thoughts on the newly proposed ‘photogravitational assist’
method of deceleration, because for years his own method for the Epsilon Eridani mission — a ‘staged’ sail that separates, so that one
sail ring reflects laser light back onto another — has been the only method I’ve seen for slowing a sailcraft down for orbital insertion
at another star.

JULIANNE: Tak tohle je nejpříjemnější zakončení dnešního hektického dne. :)

A půjdu hned s pravdou ven: už v půlce prefixu jsem přestal číst, a ihned mocně zagooglil, mám ho totiž v povědomí
(jako 95% z těch 500+ kosmonautů) jen velice matně. Ale svitlo mi za chvilku (hlavně krz ISS). Velmi sympatický a
charismatický chlapík.

Většinu rozhovorů s kosmonauty bohužel nedočtu - ne že by nebyly zajímavé - ale dění kolem pilotované kosmonautiky
nepatří mezi má nejrajcovnější témata (tohle je čistě subjektivní, omlouvám se všem zdejším kosmonautickým skalákům).
Tvůj rozhovor jsem si užil právě díky skvělému výběru zvolených témat, která mě samotného zajímají, a je z toho cítit,
že i jeho bavilo odpovídat. Paráda, jen tak dál! Díky.

(Jen u té spolupráce s Čínou mám problém: nevědomé skřípění zubů, ale to se ani jeho ani tvého rozhovoru netýká...
Asi je skutečně potřeba to propojit. Všimla sis zprávy o spolupráci FASTu a SETI? Btw: dostal jsem už druhou moc zajímavou
zprávu ohledně výkonu FASTu a Areciba, ale nedovolím si to pustit ven, dokud si v tom neudělám pořádek, a druhak by to mohl
kdokoliv napadnout, protože oba zdroje informací jsou profesně s Arecibo/NAIC spojeni, ale snad neudělám botu, když napíšu,
že je všechno zase trochu jinak (už zase slyším to skřípání!...:-D)


JULIANNE: V tomhle snad už konečně můžu mluvit i za ostatní. Rozhodně budeme rádi
za všechny nové články, těšíme se! Jen z toho výčtu jmen máš pořádně nakročíno! :)

Teď už mi zbývá jen dopřepsat záznamy rozhovorů se Stuartem Kauffmanem a Christophem Sotinem (toho pak určitě zase vložím sem). A Douglasem Vakochem. A Jimem Kakaliosem. Kde je pořádná speech-to-text recognition, když ji člověk potřebuje?

Přihazuji jeden další rozhovor :). Astronauta Leroye Chiao jsem sice nestihla vyzpovídat naživo v Praze, ale popovídala jsem si s ním po Skypu krátce nato.

Experiments suggest red spot on Pluto may have come about from impact that formed Charon
https://phys.org/news/2017-02-red-pluto-impact-charon.html

A combined team of researchers from several institutions in Japan has found evidence that suggests Pluto's distinctive red spot
may have developed after a massive collision with a comet or other object. In their paper published in the journal Nature Astronomy,
the researchers detail experiments they conducted that showed that the red spot on Pluto may have come about due to pools that
developed on the dwarf planet's surface after a collision.

UH Research Finds Evidence of 2 Billion Years of Volcanic Activity on Mars - University of Houston
http://www.uh.edu/news-events/stories/2017/February/02012017mars-volcano-meteorite.php

Analysis of a Martian meteorite found in Africa in 2012 has uncovered evidence of at least 2 billion years of volcanic
activity on Mars. This confirms that some of the longest-lived volcanoes in the solar system may be found on the Red Planet.

Shield volcanoes and lava plains formed from lava flowing over long distances, similar to the formation of the Hawaiian Islands.
The largest Martian volcano, Olympus Mons, is nearly 17 miles high. That’s almost triple the height of Earth’s tallest volcano,
Mauna Kea, at 6.25 miles.

Impact ejecta is material that is thrown up and out of the surface of a planet as a result of the impact of an meteorite, asteroid or comet.
The material that was originally beneath the surface of the planet then rains down onto the environs of the newly formed impact crater.

Swirling spirals at the north pole of Mars / Mars Express / Space Science / Our Activities / ESA
http://www.esa.int/...tivities/Space_Science/Mars_Express/Swirling_spirals_at_the_north_pole_of_Mars

A new mosaic from ESA’s Mars Express shows off the Red Planet’s north polar ice cap and its distinctive dark spiralling troughs.

The mosaic was generated from 32 individual orbit ‘strips’ captured between 2004 and 2010, and covers an area of around a million
square kilometres.

The ice cap is a permanent fixture, but in the winter season – as it is now in early 2017 – temperatures are cold enough for around
30 percent of the carbon dioxide in the planet’s atmosphere to precipitate onto the cap, adding a seasonal layer up to a metre thick.
