Around 300 million years old and 2050 light-years away.Nov 17, 2023 NGC869 and NGC884 - The Double Cluster in Perseus2 viewsOpen clusters - NGC869 is center/bottom, 7460 light-years away; NGC884, top, 7640 light-years awayNov 17, 2023 Messier 7 - Ptolemy's Cluster1 viewsAn open cluster of stars in the constellation Scorpius. Southernmost Messier object. 980 light years distant. Also designated NGC 6475.Nov 17, 2023 M45 - The Pleiades4 viewsOpen star cluster in the constellation Taurus. Nearest Messier object to Earth (444 light-years).Sep 26, 2023 M11 - The Wild Duck Cluster5 viewsOne of the richest, most compact and most massive open clusters known; estimates range from 3,700 to 11,000 solar masses. Radius 95 light-years. 6,120 light-years away, in the constellation Scutum. Supposedly the cluster resembles a flying flock of ducks, although as far as I can tell it could just as well be geese, crows or magpies.Aug 02, 2022 NGC 5139 - Omega Centauri Cluster7 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 M15 - Globular cluster in Pegasus15 viewsContaining over 100,000 stars, 175 light-years in diameter, 33,600 light years from Earth. This is one of the oldest (12 billion years) and most densely packed globulars in the Milky Way.Sep 14, 2020 NGC 7789 - Open Cluster in Cassiopeia8 viewsDiscovered by Caroline Herschel in 1783 and nicknamed "Caroline's Rose" because of its supposed floral appearance. Distance from Earth is about 7,600 light-years.Aug 28, 2019 Messier 24 - "Small" Sagittarius Star Cloud10 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. Aug 12, 2019 NGC 6520 and Barnard 869 viewsNGC 6520 is an open cluster in the constellation Sagittarius, consisting of about 25 stars of magnitude 9-12. At its western edge (to the right in this image) lies the dark nebula Barnard 86 (B86).Aug 10, 2019 NGC 6522 - Globular Cluster in Sagittarius7 viewsPossibly the oldest star cluster in the Milky Way,[4] with an age of more than 12 billion years. Located in an area of the sky known as Baade's Window, named for the astronomer Walter Baade, who first recognized its signficance. Baade's Window is an area of the sky with relatively low amounts of interstellar dust along the line of sight from the Earth, allowing unobstructed observation of the center of our Milky Way galaxy.Aug 09, 2019 Messier 39 - Open Cluster in Cygnus10 viewsAn open cluster in the constellation Cygnus the Swan; distance 1010 light-years.Jun 24, 2019 17 files on 2 page(s) 1 2 Debug Info  Debug Output: show / hide Select All USER: ------------------ Array ( [ID] => 663bc961081116e2ec0edaeead8ae0da [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] (0.16 ms) [1] => SELECT * FROM cm_plugins ORDER BY priority [include/plugin_api.inc.php:48] (0.12 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:357] (0.15 ms) [3] => SELECT group_name FROM cm_usergroups WHERE group_id= 3 [bridge/udb_base.inc.php:362] (0.14 ms) [4] => SELECT COUNT(*) FROM cm_categorymap WHERE group_id in (3) [bridge/udb_base.inc.php:375] (0.12 ms) [5] => SELECT aid FROM cm_albums WHERE moderator_group IN (3) [include/init.inc.php:271] (0.11 ms) [6] => SELECT lang_id FROM cm_languages WHERE enabled='YES' [include/init.inc.php:334] (0.17 ms) [7] => DELETE FROM cm_banned WHERE expiry < '2024-05-14 19:23:52' [include/init.inc.php:448] (0.42 ms) [8] => SELECT null FROM cm_banned WHERE ('3.139.81.210' LIKE ip_addr ) AND brute_force=0 LIMIT 1 [include/init.inc.php:464] (0.28 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] (0.1 ms) [10] => SELECT category, title, aid, keyword, description, alb_password_hint FROM cm_albums WHERE aid = 11 [thumbnails.php:136] (0.3 ms) [11] => 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:2943] (0.11 ms) [12] => SELECT COUNT(*) FROM cm_pictures AS r INNER JOIN cm_albums AS a ON a.aid = r.aid WHERE (r.aid = 11) AND (1 OR keywords like '%27telp%') AND r.aid NOT IN (12, 51) AND approved = 'YES' [include/functions.inc.php:1614] (0.54 ms) [13] => 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 (r.aid = 11) AND (1 OR keywords like '%27telp%') AND r.aid NOT IN (12, 51) AND approved = 'YES' ORDER BY ctime DESC, pid DESC LIMIT 0 ,12 [include/functions.inc.php:1630] (0.66 ms) [14] => SELECT extension, mime, content, player FROM cm_filetypes [include/functions.inc.php:5952] (0.14 ms) ) ========================== GET : ------------------ Array ( [album] => lastup [cat] => -11 ) ========================== POST : ------------------ Array ( ) ========================== COOKIE : ------------------ Array ( ) ==========================
