Source of the famous "Pillars of Creation" image produced by the Hubble Space Telescope. About 7000 light-years distant. M17 - The Swan Nebula386 viewsIn the constellation Sagittarius. Also known as the Omega or Horseshoe Nebula. A prolific star-forming region, lying 5000-6000 years from Earth. M20 - The Trifid Nebula511 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. M20 - The Trifid Nebula432 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. M27, The Dumbbell Nebula313 viewsThe first planetary nebula to be discovered, the Dumbbell is 1227 light-years from Earth in the constellation Vulpecula. M42 - The Great Nebula in Orion418 views1344 light-years away, 24 light-years across, this emission/reflection nebula is one of the brightest in the sky, as well as the closest region of massive star formation to Earth. M42 - The Great Nebula in Orion399 viewsAnother take on the Great Orion Nebula, incorporating hydrogen-alpha data. M42 - The Great Nebula in Orion463 viewsA narrowband image of the Orion Nebula, captured with a one-shot color CMOS camera and an IDAS NBZ nebula enhancement filter. M78 - Reflection Nebula in Orion450 viewsM78 - Reflection Nebula in the Orion B molecular cloud complex, 1,350 light-years from Earth. M97 - The Owl Nebula450 viewsPlanetary nebula in the constellation Ursa Major, 2030 light-years distance from Earth and about 8000 years old. The blurred appearance results from the fact that it consists of several overlapping shells of gas. The shells are not entirely concentric, but form a barrel-like structure which gives rise to the owl-like appearance. NGC 1499 - The California Nebula411 viewsAn emission nebula in the constellation Perseus, so called because it resembles the State of California in shape (though not in this image). About 1000 light-years from Earth. NGC1499 - The California Nebula, narrowband version448 viewsThis bizarre rendition of the California Nebula was the result of an unrepeatable experiment in mapping H-alpha and O-III to various channels in a mad orgy of improvisation. 92 files on 8 page(s) 1 2 3 4 5 6 7 8 Debug Info  Debug Output: show / hide Select All USER: ------------------ Array ( [ID] => 8838b0e30db3e07fc4f45c44469471bc [am] => 1 [liv_a] => Array ( ) ) ========================== 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] (0.31 ms) [1] => SELECT * FROM cm_plugins ORDER BY priority [include/plugin_api.inc.php:48] (0.15 ms) [2] => DELETE FROM `i5493328_cm1`.cm_sessions WHERE time < 1764557569 AND remember = 0 [bridge/udb_base.inc.php:59] (0.84 ms) [3] => DELETE FROM `i5493328_cm1`.cm_sessions WHERE time < 1763351569 [bridge/udb_base.inc.php:59] (0.45 ms) [4] => UPDATE cm_config SET value = 1764561169 WHERE name = 'session_cleanup' [bridge/udb_base.inc.php:59] (0.53 ms) [5] => 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] (0.24 ms) [6] => SELECT group_name FROM cm_usergroups WHERE group_id= 3 [bridge/udb_base.inc.php:362] (0.18 ms) [7] => SELECT COUNT(*) FROM cm_categorymap WHERE group_id in (3) [bridge/udb_base.inc.php:375] (0.16 ms) [8] => SELECT aid FROM cm_albums WHERE moderator_group IN (3) [include/init.inc.php:271] (0.11 ms) [9] => SELECT lang_id FROM cm_languages WHERE enabled='YES' [include/init.inc.php:334] (0.17 ms) [10] => DELETE FROM cm_banned WHERE expiry < '2025-12-01 03:52:49' [include/init.inc.php:448] (0.58 ms) [11] => SELECT null FROM cm_banned WHERE ('216.73.216.55' LIKE ip_addr OR '' LIKE ip_addr ) AND brute_force=0 LIMIT 1 [include/init.inc.php:464] (0.46 ms) [12] => SELECT aid FROM cm_albums WHERE (1 AND visibility != 0 AND visibility != 10000 AND visibility NOT IN (3)) [include/functions.inc.php:1110] (0.16 ms) [13] => SELECT category, title, aid, keyword, description, alb_password_hint FROM cm_albums WHERE aid = 2 [thumbnails.php:96] (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] (0.15 ms) [15] => SELECT null FROM cm_albums WHERE category < 10000 AND uploads='YES' AND (visibility = '0' OR visibility IN (3)) AND aid = '2' [include/themes.inc.php:2063] (0.76 ms) [16] => SELECT null FROM cm_albums WHERE category < 10000 AND uploads='YES' AND (visibility = '0' OR visibility IN (3)) AND aid = '2' [include/themes.inc.php:2063] (0.29 ms) [17] => SELECT title, keyword FROM cm_albums WHERE aid = 2 [include/functions.inc.php:2461] (0.31 ms) [18] => SELECT COUNT(*) FROM cm_pictures WHERE ((aid='2' AND aid NOT IN (12, 51) ) OR (keywords like '%27telp%' AND aid NOT IN (12, 51) )) AND approved='YES' [include/functions.inc.php:1408] (3.01 ms) [19] => 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 WHERE ((aid = 2 AND aid NOT IN (12, 51) ) OR (keywords like '%27telp%' AND aid NOT IN (12, 51) ))AND approved='YES' ORDER BY position DESC, pid DESC LIMIT 32 ,12 [include/functions.inc.php:1439] (46.09 ms) [20] => SELECT extension, mime, content, player FROM cm_filetypes [include/functions.inc.php:5952] (0.3 ms) ) ========================== GET : ------------------ Array ( [album] => 2 [page] => 5 ) ========================== POST : ------------------ Array ( ) ========================== COOKIE : ------------------ Array ( ) ==========================
