NASA na internetu objavila na hiljade neverovatnih slika svemira

[Alexdelarge]

Ove slike će vam oduzeti dah! Reč je o poslednjem u nizu projektu NASA-e, tokom koga je korišćen visoko tehnološki teleskop za mapiranje neba. Tom prilikom snimljene su neverovatne fotografije galaksije, asteroida i zvezda koje nikada ranije nisu viđene. A, dostupne su svakome ko ima internet.

Ova galerija sadrži niz od dva i po miliona zapanjujućih fotografija svemira, koje uključuju i 33.000 novih asteroida koji plove između Marsa i Jupitera, a koji su do sada bili nepoznati, kao i 20 sasvim novih kometa.


NASA je ovaj projekat započela 2009. godine, kada je lansirala infra cerveni teleskop vrednosti 220.000 miliona dolara, pod nazivom "Wide-field Infrared Survey Explorer" (Širokopojasni infracrveni pretraživač okoline) ili skraćeno WISE. On je zahvaljujući najsavršenijoj tehnologiji i kamerama koja je ikada razvijena svo ovo vreme skenirao kosmos.

Zahvaljujući tome, njegov objektiv može da "pokupi" bilo kakav toplotni sjaj, a zahvaljujući novoj tehnologiji primećeni su i prašnjavi, hladni i udaljeni objekti koji ne mogu da se primete običnim teleskopom.


Na jednoj od neverovatnih slika, koje je NASA predstavila, nalazi se i kometa "Siding Spring", koja je primećena kako proleće preko neba ostavljajući iza sebe skoro zastrašujući trag, ali i gigantska galaksija Andromeda koja je udaljena od Zemlje 2.5 miliona svetlosnih godina.

"Spektakularni, novi podaci koji su tek objavljeni, podsećaju nas na to da imamo mnogo novih komšija", rekla je Pete Šulc, jedna od naučnika sa Braun univerziteta koji su bili uključeni u projekat.


Do sada, NASA je objavila samo deo slika, ali uskoro planira da postavi još. Da biste videli slike posetite sajt, www.nasa.gov/wise.


Teleskop radi do oktobra
Super teleskop WISE prestaje sa radom u oktobru mesecu ove godine, jer će mu se istrošiti rashladna tečnost, zbog čega neće moći da rashlađuje instrumente koji su veom osetljivi na toplotu i da posmatra udaljene objekte. Zato će ovih nekoliko poslednjih meseci, umesto da snima svemir, kružiti oko Zemlje, kako bi na vreme primetio neki od potencijalno opasnih asteroida ili kometa.

Lepo! Obožavam svemirske slike i redovno ih imam na desktopu.

[mac]

Ja sam prvo skinuo desktop temu NASA Hidden Universe, a onda u nju dodao još sa sledeće stranice http://jootix.com/cat/669/Space/ . I meni je lepo, 30 MB u 32 slike maglina i galaksija.

Aussie student finds universe's 'missing mass'

– Fri May 27, 4:01 am ET

SYDNEY (AFP) – A 22-year-old Australian university student has solved a problem which has puzzled astrophysicists for decades, discovering part of the so-called "missing mass" of the universe during her summer break.

Undergraduate Amelia Fraser-McKelvie made the breakthrough during a holiday internship with a team at Monash University's School of Physics, locating the mystery material within vast structures called "filaments of galaxies".

Monash astrophysicist Dr Kevin Pimbblet explained that scientists had previously detected matter that was present in the early history of the universe but that could not now be located.

"There is missing mass, ordinary mass not dark mass ... It's missing to the present day," Pimbblet told AFP.

"We don't know where it went. Now we do know where it went because that's what Amelia found."

Fraser-McKelvie, an aerospace engineering and science student, was able to confirm after a targeted X-ray search for the mystery mass that it had moved to the "filaments of galaxies", which stretch across enormous expanses of space.

Pimbblet's earlier work had suggested the filaments as a possible location for the "missing" matter, thought to be low in density but high in temperature.

Pimbblet said astrophysicists had known about the "missing" mass for the past two decades, but the technology needed to pinpoint its location had only become available in recent years.

He said the discovery could drive the construction of new telescopes designed to specifically study the mass.

Pimbblet admitted the discovery was primarily academic, but he said previous physics research had led to the development of diverse other technologies.

"Whenever I speak to people who have influence, politicians and so on, they sometimes ask me 'Why should I invest in physics pure research?'. And I sometimes say to them: 'Do you use a mobile phone? Some of that technology came about by black hole research'.

"The pure research has knock-on effects to the whole society which are sometimes difficult to anticipate."

Volela bih da ima više teksta o nedostajućoj masi. Nisam čula za to. Potražiću po netu.

O, da. Ni to nisam znala. Ali dobro, ja bar nikad ne bih postavljala pitanje svrhe finansiranja istraživanja u čistoj fizici.

зум ради!

What you see above is the largest true-color photograph of the night sky ever created, shot by 28-year-old amateur astrophotographer Nick Risinger using six astronomical cameras. It's not just the view of the sky from one location, but is instead a 360-panoramic view of the sky taken by trekking 60,000 miles across the western United States and South Africa starting in March 2010. The final image is composed of 37,000 separate photographs.

NASA Telescope Confirms Alien Planet in Habitable Zone 

This story was updated at 12:15 p.m. ET.
MOUNTAIN VIEW, Calif. — NASA's planet-hunting Kepler spacecraft has confirmed the discovery of its first alien world in its host star's habitable zone — that just-right range of distances that could allow liquid water to exist — and found more than 1,000 new explanet candidates, researchers announced today (Dec. 5).
The new finds bring the Kepler space telescope's total haul to 2,326 potential planets in its first 16 months of operation.These discoveries, if confirmed, would quadruple the current tally of worlds known to exist beyond our solar system, which recently topped 700.
The potentially habitable alien world, a first for Kepler, orbits a star very much like our own sun. The discovery brings scientists one step closer to finding a planet like our own — one which could conceivably harbor life, scientists said.
"We're getting closer and closer to discovering the so-called 'Goldilocks planet,'" Pete Worden, director of NASA's Ames Research Center in Moffett Field, Calif., said during a press conference today. [Gallery: The Strangest Alien Planets]
The newfound planet in the habitable zone is called Kepler-22b. It is located about 600 light-years away, orbiting a sun-like star.
Kepler-22b's radius is 2.4 times that of Earth, and the two planets have roughly similar temperatures. If the greenhouse effect operates there similarly to how it does on Earth, the average surface temperature on Kepler-22b would be 72 degrees Fahrenheit (22 degrees Celsius).
Hunting down alien planets
The $600 million Kepler observatory launched in March 2009 to hunt for Earth-size alien planets in the habitable zone of their parent stars, where liquid water, and perhaps even life, might be able to exist.
Kepler detects alien planets using what's called the "transit method." It searches for tiny, telltale dips in a star's brightness caused when a planet transits — or crosses in front of — the star from Earth's perspective, blocking a fraction of the star's light.
The finds graduate from "candidates" to full-fledged planets after follow-up observations confirm that they're not false alarms. This process, which is usually done with large, ground-based telescopes, can take about a year.
The Kepler team released data from its first 13 months of operation back in February, announcing that the instrument had detected 1,235 planet candidates, including 54 in the habitable zone and 68 that are roughly Earth-size.
Of the total 2,326 candidate planets that Kepler has found to date, 207 are approximately Earth-size. More of them, 680, are a bit larger than our planet, falling into the "super-Earth" category. The total number of candidate planets in the habitable zones of their stars is now 48.
To date, just over two dozen of these potential exoplanets have been confirmed, but Kepler scientists have estimated that at least 80 percent of the instrument's discoveries should end up being the real deal.
More discoveries to come
The newfound 1,094 planet candidates are the fruit of Kepler's labors during its first 16 months of science work, from May 2009 to September 2010. And they won't be the last of the prolific instrument's discoveries.
"This is a major milestone on the road to finding Earth's twin," Douglas Hudgins, Kepler program scientist at NASA headquarters in Washington, D.C., said in a statement.
Mission scientists still need to analyze data from the last two years and on into the future. Kepler will be making observations for a while yet to come; its nominal mission is set to end in November 2012, but the Kepler team is preparing a proposal to extend the instrument's operations for another year or more.
Kepler's finds should only get more exciting as time goes on, researchers say.
"We're pushing down to smaller planets and longer orbital periods," said Natalie Batalha, Kepler deputy science team lead at Ames.
To flag a potential planet, the instrument generally needs to witness three transits. Planets that make three transits in just a few months must be pretty close to their parent stars; as a result, many of the alien worlds Kepler spotted early on have been blisteringly hot places that aren't great candidates for harboring life as we know it.
Given more time, however, a wealth of more distantly orbiting — and perhaps more Earth-like — exoplanets should open up to Kepler. If intelligent aliens were studying our solar system with their own version of Kepler, after all, it would take them three years to detect our home planet.
"We are getting very close," Batalha said. "We are homing in on the truly Earth-size, habitable planets."

Kao da ste na Marsu: NASA objavila novu spektakularnu fotogafiju Crvene planete

Ljudska noga još nije stupila na Mars, ali NASA je objavila novu spektakularnu panoramsku fotografiju Crvene planete, za koju tvrdi da vam pruža osećaj "kao da ste tamo".

Na fotografiji, snimljenoj kolornom kamerom koja se nalazi na vrhu Nasinog rovera "Oportjuniti", vide se sveži tragovi rovera, kao i njegovi solarni paneli. Tu je i krater nastao možda i pre milijardu godina, kao i grubi teren na kojem je Nasino robotsko vozilo provelo marsovsku zimu.

Fotografija je zapravo kombinacija 817 slika koje je panoramska kamera na vrhu "Oportjunitija" snimila dok je mirovala tokom zime na Marsu, između 21. decembra i 8. maja.

"Oportjuniti" i njegov blizanac "Spirit" sleteli su na Mars januara 2004. godine zbog misija za koje je u prvi mah planirano da traju samo tri meseca. "Kjuroiziti", Nasin rover poslednje generacije, trebalo bi da dotakne površinu Marsa tokom avgusta.



Ovu fotografiju vredi pogledati i u maksimalnoj rezoluciji zbog izuzetne detaljnosti.

Ne razumem odgovor.  A pitanje lepo zahteva "da-ne" odgovor. 

[mac]

Da li znam? Da. Da li se slažem da je razočaravajuće? Ne. Da li čovek može da vidi "prave boje"? Ne.
