A hned druhý problém... čím dnes začít? Vyřešila to za mně NASA. :)

Uááá.. Sice už jsem zpátky v Matrixu skoro 2 týdny, ale návrat nebyl jednoduchý. Posledních +/- 5 let jsem neměl dovolenou - co hůř - neměl jsem ani potřebu
si ji brát. Někde vevnitř jsem si dokonce říkal, že dovolená je pro lidi, co tak úplně nemají rádi svou práci a nemají silného koníčka. Než mě roznesete
na kopytech - samozřejmě jsem zjistil, že je tomu jinak. Po návratu ze Španělska mě dokonce v práci poslali na další dovolenou, neboť jsem měl skoro 90 dní
volna, a to už nejde dohromady s našimi zákony. Tak jsem se otočil na podpadku, a dalších 10 dní cestoval po naši nádherné zemi - bez připojení. A byl to
úžasný zážitek. Jen jsem měl dostatek času vidět svět z jiné strany.

O to náročnější byl návrat do "digitálního vesmíru". Novinky a publikace které před zhruba dekádou zaplnily +/- týden, jsou dnes namačkány do 24 hodin.
Musel jsem tedy někde začít, a logicky zvolil "domovskou" platformu googlu s tím, že to tady na Nyxu zřejmě umřelo, a nikomu se nebude stýskat. O to větší
radost jsem měl vida, že to tu funguje. Chtěl bych moc poděkovat všem, kteří se o to zasloužili (seřadil jsem to alfabeticky, nikoliv chronologicky :D)

VINCENT_BU - tobě především, parádně ses toho ujal, a když jsem si to teď projel, tak mě to fakt potěšilo - máme hodně podobné úchylky. :)

Teď mám bohužel hektiku i v práci, a snažím se to všechno synchronizovat tak, aby nedošlo k mentální újmě. Takže víkendy pořád trávím tak,
že vyjíždím mimo Matrix, a v podstatě trochu pokračuji v tom, co jsem dělal o dovolené. Pokud máte chuť a čas, pokračujte v pastování, mně
ještě určitě potrvá celkové "dosednutí na letištní plochu". Ale už jsem se rozkoukal... :)

Ještě jednou díky moc všem!

Hubble Captures Massive Dead Disk Galaxy that Challenges Theories of Galaxy Evolution
Acting as a natural telescope in space, the gravity of the extremely massive foreground galaxy cluster MACS J2129-0741 magnifies, brightens, and distorts the far-distant background galaxy MACS2129-1, which is the first example of a compact yet massive, fast-spinning, disk-shaped galaxy that stopped making stars only a few billion years after the big bang. Astronomers expected to see a chaotic ball of stars formed through galaxies merging together. Instead, they saw evidence that the stars were born in a pancake-shaped disk. The remote galaxy is three times as massive as the Milky Way but only half the size while spinning more than twice as fast as the Milky Way.

Kepler's Catalogue of Planet Candidates from Observations in the Cygnus Constellation Finalized
NASA's Kepler space telescope team has released a mission catalog of planet candidates that introduces 219 new candidates, 10 of which are near-Earth size and orbiting in their star's habitable zone, which is the range of distance from a star where liquid water could pool on the surface of a rocky planet. This is the most comprehensive and detailed catalog release of candidate exoplanets, which are planets outside our solar system, from Kepler's first four years of data. It's also the final catalog from the spacecraft's view of the patch of sky in the Cygnus constellation. With the release of this catalog, derived from data publicly available on the NASA Exoplanet Archive, there are now 4,034 planet candidates identified by Kepler. Of those, 2,335 have been verified as exoplanets. Of roughly 50 near-Earth size habitable zone candidates detected by Kepler, more than 30 have been verified.

The Kepler spacecraft continues to make observations in new patches of sky in its extended mission, searching for planets and studying a variety of interesting astronomical objects, from distant star clusters to objects such as the TRAPPIST-1 system of seven Earth-size planets, closer to home.

NASA Snímek dne v Praze! | Kalendář akcí | Astronomický informační server astro.cz
http://www.astro.cz/kalendar-akci/nasa-snimek-dne-v-praze.html
Zvažuju vejlet do Prahy, Jožku Chlachulu znám a neviděla jsem ho spoustu let, to by bylo asi zajímavé setkání!! :)

JAYME: pisal, ze pojde prec :) ale sak sa vrati :)

JAYME: to ne, a budu jen rád, když se VIRGO vrátí a zase se do toho pustí. Přišlo mi ale smutné, jak to tady v jeho nepřítomnosti, poté co odjel na dovolenou či kam, zeje prázdnotou. A nikdo jiný se k postování neměl. Popravdě, já téhle problematice zas tolik nerozumím, tak jsem zkoušel dát alespoň obecné věci. Možná jsou příliš povrchní, co já vím. Jestli máš něco zajímavého, tak sem s tím. Jinak to vypadá na prázdno. :)

VINCENT_BU: hele ty ses VIRGO co ztratil heslo nebo nakej nahradnik? :)

Cosmic Magnifying-Glass Effect Captures Universe's Brightest Galaxies
Boosted by natural magnifying lenses in space, NASA's Hubble Space Telescope has captured unique close-up views of the universe's brightest infrared galaxies, which are as much as 10,000 times more luminous than our Milky Way. The galaxy images reveal a tangled web of misshapen objects punctuated by exotic patterns such as rings and arcs. The odd shapes are due largely to the foreground lensing galaxies' powerful gravity distorting the images of the background galaxies. The unusual forms also may have been produced by spectacular collisions between distant, massive galaxies in a sort of cosmic demolition derby that existed between 8 billion and 11.5 billion years ago. These ultra-luminous, massive, starburst galaxies are very rare. We can see small details that otherwise are unimaginable, features as small as about 100 light-years or less across.

Icy Moons, Galaxy Clusters, and Distant Worlds Among Selected Targets for James Webb Space Telescope
Mission officials for NASA’s James Webb Space Telescope announced some of the science targets the telescope will observe following its launch and commissioning. These specific observations are part of a program of Guaranteed Time Observations (GTO). The broad spectrum of initial GTO observations will address all of the science areas Webb is designed to explore, from first light and the assembly of galaxies to the birth of stars and planets. Targets will range from the solar system’s outer planets (Jupiter, Saturn, Uranus, and Neptune) and icy Kuiper Belt to exoplanets to distant galaxies in the young universe. Searching for chemical fingerprints of life on Enceladus, Europa, and exoplanets like TRAPPIST-1e, Webb will be looking at some incredible things in our universe.

General relativity passes test at Milky Way’s central black hole
“It’s the first time that general relativity is really tested around a supermassive black hole,” says Aurélien Hees at the University of California, Los Angeles.

These two stars (S0-2 and S0-38) speeding around Sagittarius A* (4 million times as massive as the sun) were first discovered in the 1990s, when astronomers began tracking their movements. By observing their orbits for 19 years, Hees and his colleagues found that general relativity describes the stars’ paths perfectly. The stars show no sign of a hypothetical fifth force that would cause a deviation from the theory’s predictions.

Ordinary black holes, such as Cygnus X-1 in the constellation of the same name, are more massive than the sun, but stars that orbit them don’t provide useful tests of general relativity. This is partly because they lose gas to the black hole, which leads to their paths being altered in ways that have nothing to do with Einstein’s theory. In contrast, the two mentioned stars don’t come close enough to lose gas to the black hole.

Stars are not motionless in the sky: their positions change continuously as they move through our galaxy, the Milky Way. These motions, too slow to be appreciated with the naked eye over a human lifetime, can be captured by high-precision observations like those performed by ESA’s billion-star surveyor, Gaia. A new video, based on measurements by ESA’s Gaia and Hipparcos satellites, shows how our view of the Orion constellation will evolve over the next 450 000 years.
(The birth and demise of stars are not shown in the video.)

a jedno zpochybnění: WOW! signál byl neobvykle silný. signál z 266P/Christensen nikoliv, což mohlo být způsobeno ztrátou hmoty vypařováním za 40 let, ale závěry jsou prý předčasné a bude třeba si počkat na další studie. :)

Waltzing Brown Dwarfs
The image is a stack of 12 images made over the course of three years with the NASA/ESA Hubble Space Telescope. Using high-precision astrometry, an Italian-led team of astronomers tracked the two components of the system as they moved both across the sky and around each other.

The observed system, Luhman 16AB, is only about six light-years away and is the third closest stellar system to Earth — after the triple star system Alpha Centauri and Barnard’s Star. Despite its proximity, Luhman 16AB was only discovered in 2013 by the astronomer Kevin Luhman. The two brown dwarfs that make up the system, Luhman 16A and Luhman 16B, orbit each other at a distance of only three times the distance between the Earth and the sun, and so these observations are a showcase for Hubble’s precision and high resolution.

The Rocket That Will Eventually Take Humans to the Moon Will Launch in 4 Months
The Falcon Heavy will be the most powerful rocket in the world, capable of launching 54 metric tons (119,000 lb) of cargo and crew into space. The rocket will be used to boost the first space tourists to the Moon in a launch expected to take place in 2018. The entire journey is expected to take about six to seven days. The Falcon Heavy will likely also play a role in preparing SpaceX for the highly anticipated first manned missions to Mars, set to happen by 2025.
