Last additions NGC 3521, "flocculent" spiral galaxy in Leo260 viewsNGC 3521 is termed a "flocculent" spiral galaxy because it has patches or clumps of stars breaking up the continuity of the spiral arms. Self-propagating star formation is thought to account for the patchiness. The galaxy lies about 26 million light-years away from us.May 24, 2022 Messier 58 and the Siamese Twins228 viewsM58 is a barred spiral galaxy about 62 million light-years away in the constellation Virgo. The Siamese Twins, NGC 4567 and 4568, are colliding spiral galaxies about 60 million light-years away, in the early stages of merging; they are also nicknamed the Butterfly Galaxies.May 24, 2022 Messier 61 - Face-on Barred Spiral Galaxy in Virgo245 viewsOne of the largest members of the Virgo Cluster, M61 is a starburst galaxy, i.e. it has an unusually high rate of star formation, with an active galactic nucleus that features a massive nuclear star cluster and a supermassive black hole. It is about 53 million light-years away from Earth.May 24, 2022 NGC 4631, The Whale Galaxy217 viewsA barred spiral galaxy in the constellation Canes Venatici. Contains a central starburst - a region of intense star formation. The "calf" - the nearby dwarf galaxy - is NGC 4527.May 14, 2022 NGC 5139 - Omega Centauri Cluster249 viewsGlobular cluster in Centaurus, 17,090 light-years away. The largest-known globular cluster in the Milky Way, estimated to contain approximately 10 million stars, and a total mass equivalent to 4 million solar masses.May 13, 2022 NGC 3115 - Lenticular Galaxy in Sextans281 viewsFormerly thought to be an elliptical galaxy, now considered a lenticular (lens-shaped) galaxy because it has a disk and a central bulge of stars, but no discernible spiral structure. Distance from Earth is about 32 million light years. It is several times larger than the Milky Way galaxy.Mar 27, 2022 IC443 - Jellyfish Nebula218 viewsA galactic supernova remnant in Gemini, about 6000 light-years away.Feb 09, 2022 Medusa Nebula (Sharpless 2-274)230 viewsPlanetary Nebula in Gemini. Discovered in 1955, first thought to be a supernova remnant, but Soviet astronomers in 1971 determined it to be a planetary nebula.Feb 09, 2022 NGC 2359 - Thor's Helmet236 viewsAn emission nebula in the constellation Canis Major; about 12,000 light-years away. Consists largely of interstellar gas swept up by the central star, and partly of material from the star itself, which is an extremely hot, massive Wolf-Rayet star in a short-lived pre-supernova stage. Feb 02, 2022 NGC 7023 - the Iris Nebula in Cepheus252 viewsA bright reflection nebula in the constellation Cepheus, about 1300 light-years away. Actually NGC 7023 is the star cluster inside the nebula, which is properly designated LBN 487.Jan 31, 2022 The Horsehead Nebula in Orion236 viewsThe Horsehead Nebula, Barnard 33, is a dark nebula, silhouetted against the bright emission nebula IC 434. The large blue object to the left of IC 434 is a reflection nebula, NGC 2023. They are all found near the star Alnitak, the easternmost star in Orion's belt, which is off the frame to the right, and are 1400 light-years from Earth.Jan 18, 2022 Sharpless 2-155 - The Cave Nebula297 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.Dec 22, 2021 1722 files on 144 page(s) 1 - 28 29 30 31 32 33 34 35 36 37 38 39 40 41 - 144 Debug Info  Debug Output: show / hide Select All USER: ------------------ Array ( [ID] => dc7efcf04848654080c3abc5cfb56ac6 [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] (0.82 ms) [1] => SELECT * FROM cm_plugins ORDER BY priority [include/plugin_api.inc.php:48] (0.3 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] (0.57 ms) [3] => SELECT group_name FROM cm_usergroups WHERE group_id= 3 [bridge/udb_base.inc.php:362] (0.25 ms) [4] => SELECT COUNT(*) FROM cm_categorymap WHERE group_id in (3) [bridge/udb_base.inc.php:375] (0.51 ms) [5] => SELECT aid FROM cm_albums WHERE moderator_group IN (3) [include/init.inc.php:271] (0.18 ms) [6] => SELECT lang_id FROM cm_languages WHERE enabled='YES' [include/init.inc.php:334] (0.26 ms) [7] => DELETE FROM cm_banned WHERE expiry < '2025-10-13 19:08:54' [include/init.inc.php:448] (0.7 ms) [8] => SELECT null FROM cm_banned WHERE ('216.73.216.211' LIKE ip_addr OR '' LIKE ip_addr ) AND brute_force=0 LIMIT 1 [include/init.inc.php:464] (1.76 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] (0.25 ms) [10] => SELECT COUNT(*) FROM cm_pictures AS r INNER JOIN cm_albums AS a ON a.aid = r.aid WHERE (1) AND r.aid NOT IN (12, 51) AND approved = 'YES' [include/functions.inc.php:1614] (1.08 ms) [11] => 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 WHERE (1) AND r.aid NOT IN (12, 51) AND approved = 'YES' ORDER BY ctime DESC, pid DESC LIMIT 408 ,12 [include/functions.inc.php:1630] (67.78 ms) [12] => SELECT extension, mime, content, player FROM cm_filetypes [include/functions.inc.php:5952] (0.32 ms) ) ========================== GET : ------------------ Array ( [album] => lastup [cat] => 0 [page] => 35 ) ========================== POST : ------------------ Array ( ) ========================== COOKIE : ------------------ Array ( ) ==========================
