The Cosmic Peanut - NGC 7354

    ... or star cluster, or planetary nebula, or something else. Just starting a discussion to keep track of this one. We have the usual ring of dust and gas but it's the very big, bright overexposed centre that has everyone puzzled.

    I think it's NGC 7354, a planetary nebula. Found it via Milkman - although when I tried before it didn't come up. :\ See what you think. Here's the Simbad link. The stars match and the coordinates are right. Go to the interactive AladinLite viewer for a wider look.

    This is Hubble's view (via Wikipedia):

    how can these two pictures show the same? ist totally different, isn`t it

    here is another wide field shot, in the lower right corner: http://talk.milkywayproject.org/#/subjects/AMW00035ek

    and here you may have another similar object: http://talk.milkywayproject.org/#/subjects/AMW00002hk

    I think the Hubble image used different wavelengths which would account for the difference in appearance. Here's an image which looks a bit more like ours (scroll down a bit). You can see that the stars match up too though the infrared images are confusing at times.The link you posted to a wide-field shot shows a different part of the Milky Way (I checked the coordinates on Milkman). So NGC 7354 is still my best guess - though I'm quite prepared to be wrong! 😃 It's definitely an odd looking thing. I'll ask again if someone from the team can take a look.

    And I think you're right about the similar object you linked to.

    It most certainly is NGC 7354. Nice catch! I used this link to compare the nearby stars.

    Cheers

    absolutly right, didnt recognize different wavelenghts.. and the surrounding stars of course. was kinda shocked about the different appearence and inclination. its a very nice object
