Härän molekyylipilvi - 29.11.2016 at 05.07 Kankaanpää Observation number 58613

Visibility Unclassified

Tero Hirvikoski, Ursa (Länsi-Suomi)

Bull molecular cloud photographed on the night of November 28-29. Of the large star-forming regions of the Milky Way, the cloud is closest to us, about 450 light-years away. The open star cluster in the lower right of the image acts as a good "matchbox" for perceiving the apparent diameter of the molecular cloud. The cloud is very dim and required lengthy processing to emerge.

In the direction of the dark fog B22 visible on the left, there is a small line of line which, by looking at the raw images, revealed a trace left by a slowly moving point of light. I made an animation of the item which can be found at . The shooting of the series started on 11/28/2016 6:28 PM UTC and ended on 11/29/2016 3:07 AM UTC.

Vesa Pennanen identified the target as an asteroid 914 Palisana, thanks to him.

      Open cluster is an irregular group of tens or hundreds of stars. It can be visible as separate stars or a bit fuzzy spot with small instrument.

      There is the open cluster M52 on the right edge of the image. The red emission nebula is the Bubble Nebula. Image Jyrki Grönroos.

  • Nebulae
    • Dark nebula info

      Dark nebulae are dust in space. It obsruct the visibility of background star and bright nebulae. Thus, the dark nebulae are seen as dark clouds in space.

      The dark nebula LDN 1302. Image Tero Turunen.


      The NGC 1333 is a reflection nebula, which includes also dark nebulae. Image Samuli Vuorinen.

    • Reflection nebula info

      Reflection nebula is gas only lit up by nearby stars. It should not be mix up with emission nebula, where hot stars nearby cause the gas glow. But then reflection nebulae are visible in the same areas with emission nebulae. The appearance of reflection nebulae is irregular, and many of them need bigger instruments to be visible.


      Reflection nebulae are glowing blue around the stars of Pleyades. Image Juha Parvio.


      The blue glowing reflection nebula NGC 1333 around the bright star is in Perseus. Image Timo Inkinen.


      The bluish reflection nebula NGC 2023 is located lower left from the Horsehead Nebula. The Horsehead Nebula itself is a dark nebula in the front of red emission nebula IC 434. In the left side there is NGC 2024 aka Flame Nebula. Image Samuli Vuorinen.


      NGC 7538 in Cepheus is a combination of reflection and emission nebula. Image Timo Inkinen.

Vautsi, mikä kuva!!

Hienosti tullut tuo asteroidi kuvaan. Olisi ehkä ihan oman havainnon paikka? Paljon ei asteroidikuvia ole listoilla.

Kiitos kommenteista. Jätin asteroidista Taivaanvahtiin itsenäisen havainnon joka löytyy täältä.
