Home > Astronomical Images > Deep Sky Most viewed - Deep Sky NGC 4725724 viewsA one-armed spiral galaxy in the constellation Coma Berenices, about 41 million light-years from Earth. This is a Seyfert galaxy, meaning that it has a very active nucleus; it is also a barred spiral and has a prominent ring structure. It is interacting with NGC 4747 in the upper left corner of the frame, resulting in severe distortion of both galaxies and producing the spectacular tidal tails seen with NGC 4747. The smaller spiral galaxy to the right of NGC 4725 is NGC 4712. Sharpless 2-171, The Teddy Bear Nebula in Cepheus723 viewsAn emission nebula, part of a larger nebula designated NGC 7822, about 2900 light years away. IC1396A - Elephant Trunk Nebula 717 viewsA narrowband (Hubble Palette) image of a dense cloud of gas and dust within a much larger region of ionized gas designated IC1396, illuminated and ionized by the massive bright star HD206267 at the upper right corner of the frame. I don't find that the shape of the nebula resembles an elephant's trunk, but rather, as Michelle Evans has suggested, a dragon named Verminthrax Pejorative from the movie Dragonslayer. Messier 104 - The Sombrero Galaxy713 views28 million light-years away in the constellation Virgo, the Sombrero is one of the most spectacular of all galaxies. Messier 24 - "Small" Sagittarius Star Cloud702 viewsMessier 24 is an enormous cloud of stars lying in the Sagittarius arm of our galaxy, at a distance of about 10,000 light years from Earth. It is about 600 light years wide and occupies an area 90 arc minutes in apparent diameter. Among other objects, M24 contains the open cluster NGC 6603, which is at the center of this image. M24 is called the Small Sagittarius Star Cloud because there is another, larger star cloud south of it in Sagittarius, consisting of stars not obscured by the interstellar dust which blocks our view of the center of the galaxy. M83 - The Southern Pinwheel Galaxy683 viewsA barred spiral galaxy about 15 million light-years away in Hydra, on the border with Centaurus. The nickname derives from its resemblance to the Northern Pinwheel Galaxy, M101. Sharpless 2-155 - The Cave Nebula681 viewsA narrowband (Hubble Palette) view of an emission nebula in Cepheus; part of an ionized HII region within a larger complex containing emission, reflection and dark nebulae. About 2400 light-years away, on the edge of the Cepheus molecular cloud. NGC 7822 - Star-forming region in Cepheus678 viewsIncludes the emission nebula Sharpless 171 and the star cluster Berkeley 59. Around 3000 light-years from Earth. NGC6992 - The Eastern Veil Nebula662 viewsPart of the Cygnus Loop, a supernova remnant in Cygnus. Also known as the Network Nebula. M20 - The Trifid Nebula661 viewsA combination of an open cluster of stars, an emission nebula (the lower, red portion), a reflection nebula (the upper, blue portion) and a dark nebula (which accounts for the gaps dividing the nebula into lobes). About 5000 light-years away in the constellation Sagittarius. Messier 90, Spiral Galaxy in Virgo655 views59 million light-years away. Contains little gas and dust and hence does not have much star formation; believed to be evolving into a lenticular galaxy. NGC6302 - The Bug Nebula654 viewsA bipolar planetary nebula in the constellation Scorpius. Also known as the Butterfly Nebula, but a larger telescope than the 5" refractor used to capture this image is needed to show the pattern clearly; it shows up well in Hubble images. In this image, the nebula looks more like a bug squashed on a car windshield. 161 files on 14 page(s) 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Debug Info  Debug Output: show / hide Select All USER: ------------------ Array ( [ID] => 899beac2791c199719eba8a117416c28 [am] => 1 ) ========================== USER DATA: ------------------ Array ( [user_id] => 0 [user_name] => Guest [groups] => Array ( [0] => 3 ) [group_quota] => 0 [can_rate_pictures] => 1 [can_send_ecards] => 0 [can_post_comments] => 0 [can_upload_pictures] => 0 [can_create_albums] => 0 [pub_upl_need_approval] => 1 [priv_upl_need_approval] => 1 [access_level] => 3 [disk_max] => 0 [disk_min] => 0 [has_admin_access] => 0 [group_name] => Guests [can_create_public_albums] => 0 [can_see_all_albums] => 0 [group_id] => 3 [allowed_albums] => Array ( ) ) ========================== Queries: ------------------ Array ( [0] => SELECT name, value FROM cm_config [include/init.inc.php:177] (0.53 ms) [1] => SELECT * FROM cm_plugins ORDER BY priority [include/plugin_api.inc.php:48] (0.48 ms) [2] => SELECT MAX(group_quota) AS disk_max, MIN(group_quota) AS disk_min, MAX(can_rate_pictures) AS can_rate_pictures, MAX(can_send_ecards) AS can_send_ecards, MAX(can_post_comments) AS can_post_comments, MAX(can_upload_pictures) AS can_upload_pictures, MAX(can_create_albums) AS can_create_albums, MAX(has_admin_access) AS has_admin_access, MAX(access_level) AS access_level, MIN(pub_upl_need_approval) AS pub_upl_need_approval, MIN( priv_upl_need_approval) AS priv_upl_need_approval FROM cm_usergroups WHERE group_id in (3) [bridge/udb_base.inc.php:350] (0.65 ms) [3] => SELECT group_name FROM cm_usergroups WHERE group_id= 3 [bridge/udb_base.inc.php:362] (0.28 ms) [4] => SELECT COUNT(*) FROM cm_categorymap WHERE group_id in (3) [bridge/udb_base.inc.php:375] (0.23 ms) [5] => SELECT aid FROM cm_albums WHERE moderator_group IN (3) [include/init.inc.php:271] (0.31 ms) [6] => SELECT lang_id FROM cm_languages WHERE enabled='YES' [include/init.inc.php:334] (0.27 ms) [7] => DELETE FROM cm_banned WHERE expiry < '2026-04-30 13:53:01' [include/init.inc.php:448] (1.41 ms) [8] => SELECT null FROM cm_banned WHERE ('216.73.217.30' LIKE ip_addr OR '' LIKE ip_addr ) AND brute_force=0 LIMIT 1 [include/init.inc.php:464] (0.65 ms) [9] => SELECT aid FROM cm_albums WHERE (1 AND visibility != 0 AND visibility != 10000 AND visibility NOT IN (3)) [include/functions.inc.php:1110] (0.22 ms) [10] => SELECT name FROM cm_categories WHERE cid = 13 [thumbnails.php:157] (0.23 ms) [11] => SELECT rgt, lft, depth FROM cm_categories WHERE cid = 13 LIMIT 1 [include/functions.inc.php:44] (0.25 ms) [12] => SELECT cid FROM cm_categories WHERE lft BETWEEN 6 AND 7 [include/functions.inc.php:49] (0.14 ms) [13] => SELECT keyword FROM cm_albums WHERE category IN (13) [include/functions.inc.php:57] (0.17 ms) [14] => SELECT p.cid, p.name FROM cm_categories AS c, cm_categories AS p WHERE c.lft BETWEEN p.lft AND p.rgt AND c.cid = 13 ORDER BY p.lft [include/functions.inc.php:2940] (0.16 ms) [15] => SELECT COUNT(*) FROM cm_pictures AS r INNER JOIN cm_albums AS a ON a.aid = r.aid INNER JOIN cm_categories AS c2 ON c2.cid = category WHERE (c2.lft BETWEEN 6 AND 7) AND (1 OR keywords like '%27telp%' OR keywords like '%27telp%' OR keywords like '%27telp%') AND r.aid NOT IN (12, 51) AND approved = 'YES' AND hits > 0 [include/functions.inc.php:1717] (6.84 ms) [16] => SELECT r.pid, r.aid, filepath, filename, url_prefix, pwidth, pheight, filesize, ctime, r.title, r.keywords, r.votes, pic_rating, hits, caption, r.owner_id, user1, user2, user3, user4 FROM cm_pictures AS r INNER JOIN cm_albums AS a ON a.aid = r.aid INNER JOIN cm_categories AS c2 ON c2.cid = category WHERE (c2.lft BETWEEN 6 AND 7) AND (1 OR keywords like '%27telp%' OR keywords like '%27telp%' OR keywords like '%27telp%') AND r.aid NOT IN (12, 51) AND approved = 'YES' AND hits > 0 ORDER BY hits DESC, pid ASC LIMIT 0 ,12 [include/functions.inc.php:1734] (8.97 ms) [17] => SELECT extension, mime, content, player FROM cm_filetypes [include/functions.inc.php:5952] (2.19 ms) ) ========================== GET : ------------------ Array ( [album] => topn [cat] => 13 ) ========================== POST : ------------------ Array ( ) ========================== COOKIE : ------------------ Array ( ) ==========================
