Event Horizon - Astronomical and Terrestrial Images

Home > Astronomical Images > Deep Sky > Nebulae Nebulae Medusa Nebula (Sharpless 2-274)419 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. IC443 - Jellyfish Nebula411 viewsA galactic supernova remnant in Gemini, about 6000 light-years away. NGC 7293 - The Helix Nebula in Aquarius459 viewsOne of the closest planetary nebulae, at only 650 light-years from Earth. Around 10,600 years old and 2.5 light-years in diameter. Sometimes known as the "Eye of God" or the "Eye of Sauron." NGC 6992 - Eastern Veil Nebula433 viewsAlong with NGC 6960 and other objects, the Eastern Veil is a component of the Veil Nebula in the constellation Cygnus. It is a cloud of hot, ionized gas composed of oxygen, sulfur and hydrogen. NGC 6543 - Cat's Eye Nebula446 viewsA structurally very complex planetary nebula about 3000 light-years from Earth in the constellation Draco. In large-telescope images it has the appearance of a cat's eye, but in my 5" refractor it appears simply as a bright blue star with a halo. The small spiral galaxy off to the left is probably NGC 6552. NGC7000 - The North American Nebula472 viewsNarrowband image of an H-II emission nebula in the constellation Cygnus; only part of the nebula is visible since it is too large to fit entirely in the field of view of the telescope. 2,590 light-years distant and 90 light-years across. NGC 6888 - The Crescent Nebula502 viewsAn emission nebula in the constellation Cygnus, about 5000 light-years away from Earth; formed by the fast stellar wind from the Wolf-Rayet star WR 136 colliding with and energizing slower-moving matter ejected by the star when it became a red giant around 250,000 to 400,000 years ago. NGC6302 - The Bug Nebula449 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. 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] => 42cb97c9329233c9459f7e7729b6f4fb [am] => 1 [liv_a] => Array ( [0] => 2 ) ) ========================== 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] (0.66 ms) [1] => SELECT * FROM cm_plugins ORDER BY priority [include/plugin_api.inc.php:48] (0.32 ms) [2] => SELECT session_id FROM `i5493328_cm1`.cm_sessions WHERE session_id = '934ace3d95044f1bd0ff71d33a596ce7' [bridge/udb_base.inc.php:59] (0.79 ms) [3] => INSERT INTO `i5493328_cm1`.cm_sessions (session_id, time) VALUES ('934ace3d95044f1bd0ff71d33a596ce7', 1764559099) [bridge/udb_base.inc.php:59] (0.51 ms) [4] => 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] (0.26 ms) [5] => SELECT group_name FROM cm_usergroups WHERE group_id= 3 [bridge/udb_base.inc.php:362] (0.18 ms) [6] => SELECT COUNT(*) FROM cm_categorymap WHERE group_id in (3) [bridge/udb_base.inc.php:375] (0.18 ms) [7] => SELECT aid FROM cm_albums WHERE moderator_group IN (3) [include/init.inc.php:271] (0.18 ms) [8] => SELECT lang_id FROM cm_languages WHERE enabled='YES' [include/init.inc.php:334] (0.5 ms) [9] => DELETE FROM cm_banned WHERE expiry < '2025-12-01 03:18:19' [include/init.inc.php:448] (1.86 ms) [10] => 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] (0.62 ms) [11] => SELECT aid FROM cm_albums WHERE (1 AND visibility != 0 AND visibility != 10000 AND visibility NOT IN (3)) [include/functions.inc.php:1110] (0.57 ms) [12] => SELECT category, title, aid, keyword, description, alb_password_hint FROM cm_albums WHERE aid = 2 [thumbnails.php:96] (0.21 ms) [13] => 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) [14] => 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] (0.25 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] (0.2 ms) [16] => SELECT title, keyword FROM cm_albums WHERE aid = 2 [include/functions.inc.php:2461] (0.18 ms) [17] => 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] (0.19 ms) [18] => 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 0 ,8 [include/functions.inc.php:1439] (45.77 ms) [19] => SELECT extension, mime, content, player FROM cm_filetypes [include/functions.inc.php:5952] (0.89 ms) [20] => UPDATE cm_albums SET alb_hits = alb_hits + 1 WHERE aid = 2 [include/functions.inc.php:2895] (3.65 ms) ) ========================== GET : ------------------ Array ( [album] => 2 [page] => 8 ) ========================== POST : ------------------ Array ( ) ========================== COOKIE : ------------------ Array ( [cpg16x_data] => YToyOntzOjI6IklEIjtzOjMyOiI0MmNiOTdjOTMyOTIzM2M5NDU5ZjdlNzcyOWI2ZjRmYiI7czoyOiJhbSI7aToxO30= ) ==========================
