Explanation:

 Our Milky Way Galaxy arcs over a desolate landscape in this fantastic panoramic night skyview.

 

The otherworldly scene looks across the arid, eroded terrain of the Valle de la Luna in the Chilean Atacama desert.

 

 Just along the horizon are lights from San Pedro, Chile, as well as the small villages of Socaire and Toconao, and a tortuous road from the city of Calama to San Pedro.

 

 Taken on October 18th, the five panel mosaic also features the four galaxies easily visible from our fair planet's dark sky regions.

 

 At the far left, satellite galaxies known as the Large and Small Magellanic Clouds are framed by their terrestrial namesakes.

 

 Much fainter and at the right, beyond the Milky Way's central bulge, is the Andromeda Galaxy.

 

 The most distant in view, Andromeda lies some 2.5 million light-years away.

Explanation:

 Rich in star clusters and nebulae, the ancient constellation of Auriga, the Charioteer, rides high in northern winter night skies.

 북반구 겨울밤하늘에 높게 떠있는 마차부자리에는 성운과 성단이 풍부하다.

 

Spanning nearly 24 full moons (12 degrees) on the sky, this deep telescopic mosaic view recorded in January shows off some of Auriga's most popular sights for cosmic tourists.

 24개 보름달 (12도) 에 펼쳐진, 1월달에 기록된 이 깊은 망원 모자이크 관점은 우주 여행자들을 위한 마차부자리 가장 유명한 광경의 일부분을 과시한다.

 

The crowded field sweeps along the plane of our Milky Way galaxy in the direction opposite the galactic center.

 붐비는 지역은  은하 중심 반대 방향에 있는 우리 은하 은하수에 따라 펼쳐진다.

 

 Need directions? Near the bottom of the frame, at the Charioteer's boundary with Taurus the Bull, the bright bluish star Elnath is known as both Beta Tauri and Gamma Aurigae.

 방향이 필요한가?  사진 아래  근처, 황소자리와 함께 마차부자리 영역에 있는 밝은 청색 별 엘나스는 황소자리 베타별과 마차부자리 감마별 로 알려져있다.

 

 On the far left and almost 300 light-years away, the busy, looping filaments of supernova remnant Simeis 147 cover about 150 light-years.

 왼쪽 저 멀리 거의 300광년이나  떨어져있는  촘촘히 감겨있는  초신성잔해  Simeis 147의  필라멘트  고리가 약 150광년을 차지한다.

 

Look toward the right to find emission nebula IC 410, significantly more distant, some 12,000 light-years away.

 오른쪽에 보이는 발광성운  IC 410는 상당히 먼 거리인 12000광년이나 떨어져있다.

 

Star forming IC 410 is famous for its embedded young star cluster, NGC 1893, and tadpole-shaped clouds of dust and gas.

별 형성 지역 IC 410 은 , 가스와 먼지의 올챙이 형태 구름과  내부속에 박혀있는 어린 별 무리 , NGC 1893로 유명하다.

 

  The Flaming Star Nebula, IC 405, is just a little farther along.

타오른듯이 붉은 별 성운,  IC 405는 조금 더 멀리 있다.

 

Its red, convoluted clouds of glowing hydrogen gas are energized by hot O-type star AE Aurigae.

붉은색으로 빛나는 수소가스의 복잡한 구름은 뜨거운 O- 타입별 AE Aurigae에 의해 활력을 얻고 있다.

 

  Two of our galaxy's open star clusters, Charles Messier's M36 and M38 line up in the starfield above, familiar to many binocular-equipped skygazers.

우리은하에 속해있는 산개성단의 2개, M36 과 M38이 별시야에 줄 서 있고  많은 쌍원경 천체관측자에게 친숙하다.

Explanation:

If you visit HH 24, don't go near the particle beam jet.

This potential future travel advisory might be issued because the powerful jet likely contains electrons and protons moving hundreds of kilometers per second.

The above image was taken by the Hubble Space Telescope in infrared light in order to better understand turbulent star forming regions known as Young Stellar Objects (YSOs).

Frequently when a star forms, a disk of dust and gas circles the YSO causing a powerful central jets to appear.

In this case, the energetic jets are creating, at each end, Herbig-Haro object 24 (HH 24), as they slam into the surrounding interstellar gas.

The entire star forming region lies about 1,500 light years distant in the Orion B molecular cloud complex.

Due to their rarity, jets like that forming HH 24 are estimated to last only a few thousand years.

Explanation:

There is a road that connects the Northern to the Southern Cross but you have to be at the right place and time to see it.

북십자성에서 남십자성까지 연결되는 길이 있지만 볼려면 적절한 장소와 시간이 되어야한다.

 The road, as pictured above, is actually the central band of our Milky Way Galaxy; the right place, in this case, is dark Laguna Cejar in Salar de Atacama of Northern Chile; and the right time was in early October, just after sunset.

길은 위의 그림처럼, 사실은 우리 은하수의 중심띠이다. 이경우 적절한 장소는 칠레북부 아타카마 소금사막안에 있는 어두운 Cejar 호수 이고 적절한 시간은 10월초 막 해가 진 직후 이다.

Many sky wonders were captured then, including the bright Moon, inside the Milky Way arch; Venus, just above the Moon; Saturn and Mercury, just below the Moon; the Large and Small Magellanic Clouds satellite galaxies, on the far left; red airglow near the horizon on the image left; and the lights of small towns at several locations across the horizon.

  수 많은 멋진 경관을 이때 찍었는데 밝은 달이 포함되어있고, 아치형 은하수 안쪽에 달 바로 금성,  달 아래쪽에는 토성과 수성, 왼쪽에는 대마젤란과 소마젤란 위성은하가 있고, 이미지 왼쪽 지평선근처에는 붉은 대기광 있고, 지평선 전역에 몇몇 지점에는 작은 마을의 빛들이 보인다.

 One might guess that composing this 30-image panorama would have been a serene experience, but for that one would have required earplugs to ignore the continued brays of wild donkeys.

이 30장의 이미지 파노라마를 구성할때 고요하게 느낄수도 있지만  야생 당나귀의 지속된 울음소리를 무시할수 있는 귀마개가 필요했을 것이다.

Bright Supernova in M82
Image Credit & Copyright: Adam Block, Mt. Lemmon SkyCenter, U. Arizona

Explanation:

 Astronomers really don't find supernovae by looking for the arrows.

천문학자들은 진심으로 화살표가 찾은  초신성을 발견하지 못했다.

But in this image taken January 23rd, an arrow does point to an exciting, new supernova, now cataloged as SN 2014J, in nearby bright galaxy M82.

그러나 1월 23일에 촬영된 이 이미지 안  화살표는  밝은 은하 M82 근처에서   SN2014J 라   새롭게 목록화 된 흥미로운 새 초신성을 가르키고 있다.   

 Located near the Big Dipper in planet Earth's sky, M82 is also known as the Cigar Galaxy, a popular target for telescopes in the northern hemisphere.

지구 하늘에서 북두칠성 가까운곳에 위치한 M82는 또한 담배로 알려져 있으며 북반구에서는 망원경으로 찾을수 있는 인기있는 표적이다.

In fact, SN 2014J was first spotted as an unfamiliar source in the otherwise familiar galaxy by teaching fellow Steve Fossey and astronomy workshop students Ben Cooke, Tom Wright, Matthew Wilde and Guy Pollack at the University College London Observatory on the evening of January 21.

사실 , SN2014J 는 1월 21일 저녁 런던 대학교 천문대에대학원생 조교 Steve Fossey 와 천문학연구회 학생  Ben Cooke, Tom Wright, Matthew Wilde and Guy Pollack에 의해   친숙한 은하 안에서 친숙하지 못한 첫번째 소스로 처음에 발견되었다.

M82 is a mere 12 million light-years away (so the supernova explosion did happen 12 million years ago, that light just now reaching Earth), making supernova SN 2014J one of the closest to be seen in recent decades.

M82는 단지 1200만 광년 떨어져있으며 (즉 초신성 폭발은 12OO만년전에 발생되었고 그 빛은 지구에 막 도착하였다)  현재  최근 수십년간  발견된  가장 가까운  하나인 초신성 SN2014J 를 만들었다.

 Spectra indicate it is a Type Ia supernova caused by the explosion of a white dwarf accreting matter from a companion star.

스펙트럼에 나타난  그것은 동반성으로부터 물질을 흡수하는  백색왜성의 폭발에 의해 야기된  타입 Ia  이라 나타냈다.

By some estimates two weeks away from its maximum brightness, SN 2014J is already the brightest part of M82 and visible in small telescopes in the evening sky.

최대 밝기에서 2주  떨어진것으로 일부측정이 되며 , SN2014J 는 이미 M82의 밝은 부분이고  저녁하늘 소형망원경으로 볼 수 있다.

Spitzer's Orion

Explanation:

Few cosmic vistas excite the imagination like the Orion Nebula, an immense stellar nursery some 1,500 light-years away.

1500광년 떨어진 별들의 요람인 오리온 성운과 같은 몇몇 우주 풍경은 상상력을 자극합니다.

This stunning false-color view spans about 40 light-years across the region, constructed using infrared data from the Spitzer Space Telescope.

이 굉장히 아름다운 인공적인 색깔은 40광년를 가로지는 지역에 걸쳐져 있으며, 스피처 우주 망원경로부터 적외선 데이터를 사용하여 구성되었다. 

 Compared to its visual wavelength appearance, the brightest portion of the nebula is likewise centered on Orion's young, massive, hot stars, known as the Trapezium Cluster.

 가시광선 영역과 비교해보면 , 성운의 가장 밝은 부분은 트라페지움 성단으로 알려진 오리온의 젊고 무거우며 뜨거운 별이 모여있는곳과  똑같다.

But the infrared image also detects the nebula's many protostars, still in the process of formation, seen here in red hues.

 그러나 적외선 이미지에는  붉은색채로 보여지는 여전히 형성과정에 있는 성운의 많은 원시성을 감지한다.

 In fact, red spots along the dark dusty filament to the left of the bright cluster include the protostar cataloged as HOPS 68, recently found to have crystals of the silicate mineral olivine within its protostellar envelope.

사실, 밝은 성단의 왼편 어두운 먼지 필라멘트에 따라 나타난 붉은 점들은  HOPS 68 와 같은 목록화 된  원시성이 포함되어있고 , 현재  HOPS 68 원시성 외곽에  규산염 광물 감람석 결정이 있는것을  발견하였다.

Explanation:

 A mere seven hundred light years from Earth, in the constellation Aquarius, a sun-like star is dying.

 

 Its last few thousand years have produced the Helix Nebula (NGC 7293), a well studied and nearby example of a Planetary Nebula, typical of this final phase of stellar evolution.

 

A total of 28.5 hours of exposure time have gone in to creating this deep view of the nebula.

 

Combining narrow band image data from emission lines of hydrogen atoms in red and oxygen atoms in blue-green hues, it shows remarkable details of the Helix's brighter inner region, about 3 light-years across, but also follows fainter outer halo features that give the nebula a span of well over six light-years.

 

The white dot at the Helix's center is this Planetary Nebula's hot, central star.

 

 A simple looking nebula at first glance, the Helix is now understood to have a surprisingly complex geometry.

SOLAR ACTIVITY UPDATE: 2014 began with a bang. At 18:54 UT on January 1st, big sunspot AR1936 erupted, producing a strong M9-class solar flare. NASA's Solar Dynamics Observatory captured the explosion's extreme ultraviolet flash:

 

 

 

The movie shows a dark filament of plasma racing away from the blast site, but most of the material fell back to the stellar surface. Nevertheless, the explosion did produce a CME that could deliver a glancing blow to Earth's magnetic field later this week. NOAA analysts are still evaluating this possibility.

The M9-flare of New Year's Day followed close on the heels of an M6-flare on New Year's Eve. Sunspot AR1936 produced both explosions. The New Year's Eve event produced a minor, slow-moving CME that is not expected to disturb Earth's magnetic field if and when it does arrive.

Sunspot AR1936 is active, but new sunspot AR1944 looks even more potent. The behemoth active region emerged over the sun's southeastern limb on Jan 1st:

 

 

 

Because of foreshortening near the sun's limb, the complexity of AR1944's magnetic field is still unknown. The sheer size of the sunspot, however, suggests it is capable of strong flares. The emergence of AR1944 combined with the ongoing activity from AR1936 has prompted NOAA forecasters to raise the odds of eruptions on Jan. 2nd to 70% for M-flares and 30% for X-flares. Solar flare alerts: text, voice.

Sometimes, after your eyes adapt to the dark, a spectacular sky appears. Such was the case in 2011 March when one of the largest auroral displays in recent years appeared over northern locations like the border between Norway and Russia. Pictured in the above time-lapse movie, auroras flow over snow covered landscapes, trees, clouds, mountains and lakes found near Kirkenes, Norway. Many times the auroras are green, as high energy particles strike the Earth's atmosphere, causing the air to glow as electrons resettle into their oxygen hosts. Other colors are occasionally noticeable as atmospheric nitrogen also becomes affected. In later sequences the Moon and rising stars are also visible. With the Sun currently hovering near its time of maximum activity, there may be many opportunities to see similarly spectacular auroras personally, even from areas much closer to the equator.

Cosmic clouds seem to form fantastic shapes in the central regions of emission nebula IC 1805.

발광성운 IC1805의 중심 부분엔 환상적인 형태의 Cosmic clouds 이 형성되어있는거처럼 보인다.

 

Of course, the clouds are sculpted by stellar winds and radiation from massive hot stars in the nebula's newborn star cluster, Melotte 15.

물론, 구름들은 성운에서 갓 태어난 성단  Melotte 15 안에 있는 질량이 큰  뜨거운 별로 부터 방사선과 항성풍에 의해 조각처럼 정돈되어 있다.

 

About 1.5 million years young, the cluster stars are near the center of this colorful skyscape, along with dark dust clouds in silhouette.

약 150만년이 된 어린 성단은 실루엣 안의 검은 먼지 구름을 따라   이   화려한 skyscape의 중심 부근에 있다.

 

Dominated by emission from atomic hydrogen, the telescopic view spans about 30 light-years.

수소원자의 방출이 지배적이며,  망원시야로 약 30광년에 펼쳐져있다.

 

But wider field images reveal that IC 1805's simpler, overall outline suggests its popular name - The Heart Nebula.

그러나 광시야 이미지는  IC1805를  더 단순하게 보여지며  전반적인 윤곽을 보여주는 인기있는 있는 이름을 연상시킨다. - 하트 성운

 

IC 1805 is located along the northern Milky Way, about 7,500 light years distant toward the constellation Cassiopeia.

IC 1805는 카시오페이아 별자리쪽으로 약 7500광년 떨어져있으며 북쪽 은하수에 따라 위치하고 있다.

 

 

해석이 쉽지 않네요.. 전 금방 할지 알았는데..

그냥 맛보기를 봐주세요... 진지하게 해석하시면 안되요..
