Pleiades: The Seven Sisters Star Cluster Image Credit & Copyright: Raul Villaverde Fraile

Explanation: Have you ever seen the Pleiades star cluster? Even if you have, you probably have never seen it as large and clear as this. Perhaps the most famous star cluster on the sky, the bright stars of the Pleiades can be seen without binoculars from even the depths of a light-polluted city. With a long exposure from a dark location, though, the dust cloud surrounding the Pleiades star cluster becomes very evident. The featured exposure covers a sky area several times the size of the full moon. Also known as the Seven Sisters and M45, the Pleiades lies about 400 light years away toward the constellation of the Bull (Taurus). A common legend with a modern twist is that one of the brighter stars faded since the cluster was named, leaving only six of the sister stars visible to the unaided eye. The actual number of Pleiades stars visible, however, may be more or less than seven, depending on the darkness of the surrounding sky and the clarity of the observer's eyesight.

Pleiades: Yedi Kız Kardeş Yıldız Kümesi

Görsel & Telif: Raul Villaverde Fraile

Daha önce Ülker (Pleiades) yıldız kümesini hiç gördünüz mü? Gördüyseniz bile muhtemelen burada olduğu kadar büyük ve net görmemişsinizdir. Gökyüzündeki belki de en ünlü yıldız kümesi olan Ülker’in parlak yıldızları ışık kirliliği olan bir şehrin derinliklerinden bile dürbün kullanmadan görülebiliyor. Ama karanlık bir konumda uzun poz süresiyle Ülker yıldız kümesini çevreleyen toz bulutu oldukça belirgin hale geliyor. Bu poz gökyüzünde dolunaydan çok daha büyük bir alan kaplıyor. Aynı zamanda Yedi Kız Kardeş ya da M45 olarak da bilinen Ülker, takımyıldız Boğa (Taurus) yönünde yaklaşık 400 ışık yılı mesafede yer alıyor. Yaygın bir inanışa göre küme adlandırıldığından bu yana parlak yıldızlardan birisi sönmüş ve geride çıplak gözle görülebilecek yalnızca 6 yıldız kalmış. Ama gerçekte görülebilecek Ülker yıldızlarının sayısı, çevredeki gökyüzünün karanlık olmasına ve gözlemcinin görüşünün temizliğine bağlı olarak 7’den çok veya az olabilir.

From Astronomy Picture of the Day; March 16, 2018:

The Seagull and the DuckRaul Villaverde Fraile

Seen as a seagull and a duck, these nebulae are not the only cosmic clouds to evoke images of flight. But both are winging their way across this broad celestial landscape, spanning almost 7 degrees across planet Earth's night sky toward the constellation Canis Major. The expansive Seagull (top center) is itself composed of two major cataloged emission nebulae. Brighter NGC 2327 forms the head with the more diffuse IC 2177 as the wings and body. Impressively, the Seagull's wingspan would correspond to about 250 light-years at the nebula's estimated distance of 3,800 light-years. At the lower right, the Duck appears much more compact and would span only about 50 light-years given its 15,000 light-year distance estimate. Blown by energetic winds from an extremely massive, hot star near its center, the Duck nebula is cataloged as NGC 2359. Of course, the Duck's thick body and winged appendages also lend it the slightly more dramatic popular moniker,Thor's Helmet.

Comet Clark is near the Edge 

Sweeping through this stunning field of view, Comet 71P/Clark really is in the foreground of these cosmic clouds. The 2 panel telescopic mosaic is color enhanced and is about 5 degrees (10 full moons) across. It captures the faint comet's position on the night of May 23/24 over 5 light-minutes from Earth, very near the line-of-sight to bright star Antares and the Rho Ophiuchi cloud complex. In the frame Antares, also known as Alpha Scorpii, is at bottom center surrounded by a dusty cosmic cloud reflecting the cool giant star's yellowish light. Globular star cluster M4 shines just right of Antares, but M4 lies some 7,000 light-years away compared to Antares' 500 light-year distance. Slightly closer than Antares, Rho Ophiuchi's bluish starlight is reflected by the dust in molecular clouds toward the top. You can spot the small coma and short tail of the comet as a faint smudge near the center of the left edge of the frame. Just look for the comet's striking greenish color, produced as diatomic carbon molecules fluoresce in sunlight.

Australian photographer Andrew Campbell captured NGC 7293 — the Helix Nebula — one of the brightest and closest examples of a gas cloud created at the end of the life of a sun-like star. The remnant of the star’s core is still so energetic that it causes the previously expelled gas to fluoresce in glowing rings. Campbell created this colorful composite image from an exposure lasting 63 hours and 58 minutes, taken in Melbourne, Australia on Nov. 27, 2018.

Devil’s Head Nebula

The Gum Nebula, or Gum 12, is an emission nebula that extends 36 degrees across the night sky and is actually the very large remnant of the 12,000-year-old Vela supernova. The nebula mostly consists of hydrogen (red) and doubly ionized oxygen (blue). Australian photographer Eddie Trimarchi captured this bi-color image at Biggera Waters, Australia, on Feb. 25, 2018.

The Horsehead and Flame Nebula

British photographer Alastair Woodward snapped this image of a solitary prominence on the limb of the solar disk from Derby, UK on July 8, 2019. The photographer inverted the image during processing to show both the prominence and details of the chromosphere — the second of three layers in the sun’s outer atmosphere. The image represents approximately 700 frames from a movie shot at 40 frames per second.

Озеро Урмия — бессточное соленое озеро на севере Ирана, крупнейшее на Ближнем Востоке. За последние 20 лет оно потеряло 95% своего объема. Корабль на снимке когда-то находится в шести километрах от порта, а теперь фотограф добирался до него сначала на мотоцикле а потом пешком. Над горизонтом видны сполохи света — это засветка от одноименного с озером города, Урмии.

Наклон Сатурна меняется с периодом 15 лет, в 2017 он был максимально склонен в сторону Земли, так, что можно было хорошо разглядеть его кольца. Сейчас он отклоняется от нас, так что в следующий раз кольца с нашей планеты можно будет хорошо разглядеть только в 2032 году — но с другой стороны. Чтобы воспроизвести снимок, подобный тому, что вы видите выше, придется ждать до 2047-го.

(NASA)  NGC 4449: Close-up of a Small Galaxy

Image Credit & Copyright: Data - Hubble Legacy Archive, ESA, NASA; Processing - Domingo Pestana Galvan, Raul Villaverde Fraile

Grand spiral galaxies often seem to get all the glory. Their young, blue star clusters and pink star forming regions along sweeping spiral arms are guaranteed to attract attention. But small irregular galaxies form stars too, like NGC 4449, about 12 million light-years distant. Less than 20,000 light-years across, the small island universe is similar in size, and often compared to our Milky Way's satellite galaxy, the Large Magellanic Cloud (LMC). This remarkable Hubble Space Telescope close-up of the well-studied galaxy was reprocessed to highlight the telltale reddish glow of hydrogen gas. The glow traces NGC 4449's widespread star-forming regions, some even larger than those in the LMC, with enormous interstellar arcs and bubbles blown by short-lived, massive stars. NGC 4449 is a member of a group of galaxies found in the constellation Canes Venatici. It also holds the distinction of being the first dwarf galaxy with an identified tidal star stream.

MARTI VE ÖRDEK Bir martı ve ördek gibi görünen bu nebulalar yalnızca uçmayı anımsatan kozmik bulutlar değiller. Her ikisi de, gökyüzünde takımyıldız Büyük Köpek yönünde neredeyse 7 derece uzanan bu geniş gök manzarası boyunca kanat çırpıyorlar. Geniş Martı’nın (üst orta) kendisi de kataloglanmış iki büyük emisyon nebulasından oluşuyor. Parlak NGC 2327 başı oluştururken daha dağınık olan IC 2177 kanatları ve gövdeyi meydana getiriyor. Martı’nın kanat açıklığı, nebulanın tahmini mesafesi 3800 ışık yılında etkileyici şekilde 250 ışık yılına karşılık geliyor. Sağ altta Ördek çok daha kompakt görünüyor ve 15000 ışık yılı mesafede yalnızca 50 ışık yılı boyunca uzanıyor. Merkezine yakın aşırı büyük, sıcak yıldızın enerji yüklü rüzgarlarıyla şişirilen Ördek nebulası NGC 2359 olarak kataloglanmış. Elbette Ördek’in kalın gövdesi ve kanat şeklindeki uzantıları, biraz daha dramatik popüler takma ismi olan Thor’un Miğferi’ni de elde etmesini sağlıyor.
