370 Parallel Field with AsteroidsSome asteroids from within our Solar System have photobombed deep images of the Universe taken by the NASA/ESA Hubble Space Telescope. These asteroids reside, on average, only about 260 million kilometres from Earth — right around the corner in astronomical terms. Yet they've horned their way into this picture of thousands of galaxies scattered across space and time at inconceivably farther distances. This Hubble photo of a random patch of sky is part of the Frontier Fields survey. The colourful image contains thousands of galaxies, including massive yellowish ellipticals and majestic blue spirals. Much smaller, fragmentary blue galaxies are sprinkled throughout the field. The reddest objects are most likely the farthest galaxies, whose light has been stretched into the red part of the spectrum by the expansion of space. Intruding across the picture are asteroid trails that appear as curved or S-shaped streaks. Rather than leaving one long trail, the asteroids appear in multiple Hubble exposures that have been combined into one image. Of the 20 total asteroid sightings for this field, seven are unique objects. Of these seven asteroids, only two were earlier identified. The others were too faint to be seen previously. The trails look curved due to an observational effect called parallax. As Hubble orbits around Earth, an asteroid will appear to move along an arc with respect to the vastly more distant background stars and galaxies. The motion of Earth around the Sun, and the motion of the asteroids along their orbits, are other contributing factors to the apparent skewing of asteroid paths. All the asteroids were found manually, the majority by "blinking" consecutive exposures to capture apparent asteroid motion. Astronomers found a unique asteroid for every 10 to 20 hours of exposure time. The Frontier Fields program is a collaboration among several space telescopes and ground-based observatories to study six massive galaxy clusters and their effects.

The diagonal lines running across the image are trails of reflected light left by more than 25 of the 60 recently launched Starlink satellites as they passed through the telescope’s field of view. Although this image serves as an illustration of the impact of reflections from satellite constellations, please note that the density of these satellites is significantly higher in the days after launch (as seen here) and also that the satellites will diminish in brightness as they reach their final orbital altitude.https://asteroidiedintorni.blog/wp-content/uploads/2019/06/satelliti_giugno2019.jpgSatelliti_giugno20192022-05-19T11:55:18+00:00monthlyhttps://asteroidiedintorni.blog/2019/05/24/quaoar-occultazione-il-28-maggio-2019/https://asteroidiedintorni.blog/wp-content/uploads/2019/05/quaoar_target_occultation_20190528_2340ut.jpgQuaoar_target_occultation_20190528_2340UThttps://asteroidiedintorni.blog/wp-content/uploads/2019/05/2019_05_28-50000-quaoar.jpg2019_05_28 50000 Quaoarhttps://asteroidiedintorni.blog/wp-content/uploads/2019/05/2019_05_28-50000-quaoar-b.jpg2019_05_28 50000 Quaoar B2019-05-24T08:00:01+00:00monthlyhttps://asteroidiedintorni.blog/2019/05/23/piccolo-asteroide-colpisce-laustralia/https://asteroidiedintorni.blog/wp-content/uploads/2019/05/fireball_australiano.jpgFireball_australianohttps://asteroidiedintorni.blog/wp-content/uploads/2019/05/bolide_20190521.jpgBolide_201905212019-05-23T10:58:56+00:00monthlyhttps://asteroidiedintorni.blog/2019/04/26/distribuzione-geografica-dei-codici-assegnati-dal-minor-planet-center/https://asteroidiedintorni.blog/wp-content/uploads/2019/04/mpc_codes_europe.jpgMPC_Codes_Europehttps://asteroidiedintorni.blog/wp-content/uploads/2019/04/mpc_codes_usa.jpgMPC_Codes_USAhttps://asteroidiedintorni.blog/wp-content/uploads/2019/04/world_mpc.jpgWorld_MPChttps://asteroidiedintorni.blog/wp-content/uploads/2019/04/mpc-codes-vs-longitude.jpgMPC codes vs longitudeFigura 1 - Distribuzione in longitudine dei codici del MPC.

impression close-up of the rings around CharikloObservations at many sites in South America, including ESO’s La Silla Observatory, have made the surprise discovery that the remote asteroid Chariklo is surrounded by two dense and narrow rings. This is the smallest object by far found to have rings and only the fifth body in the Solar System — after the much larger planets Jupiter, Saturn, Uranus and Neptune — to have this feature. The origin of these rings remains a mystery, but they may be the result of a collision that created a disc of debris. This artist’s impression shows a close-up of what the rings might look like.2018-01-16T15:23:44+00:00monthlyhttps://asteroidiedintorni.blog/2017/12/14/il-triangolo-degli-hilda/https://asteroidiedintorni.blog/wp-content/uploads/2017/12/asteroidi_hilda_2.jpgASteroidi_Hilda_2https://asteroidiedintorni.blog/wp-content/uploads/2017/12/asteroidi_hilda.jpgAsteroidi_Hilda2017-12-15T11:31:19+00:00monthlyhttps://asteroidiedintorni.blog/2017/12/07/phaethon-la-cometa-di-roccia/https://asteroidiedintorni.blog/wp-content/uploads/2017/12/mappa_gnomonica_geminidi.jpgMappa_gnomonica_Geminidihttps://asteroidiedintorni.blog/wp-content/uploads/2017/12/effemeridi_phaethon_20171216_montemario_roma.jpgEffemeridi_Phaethon_20171216_MonteMario_Romahttps://asteroidiedintorni.blog/wp-content/uploads/2017/12/radiante_geminidi.jpgRadiante_Geminidihttps://asteroidiedintorni.blog/wp-content/uploads/2017/12/phaethon_map_2017.jpgPhaethon_map_2017https://asteroidiedintorni.blog/wp-content/uploads/2017/12/phaethon_orbit.jpgPhaethon_orbit2017-12-13T15:31:06+00:00monthlyhttps://asteroidiedintorni.blog/2017/10/25/oumuamua-il-primo-asteroide-interstellare/https://asteroidiedintorni.blog/wp-content/uploads/2017/10/oumuamua_interstellar_asteroid.jpgArtist’s impression of the interstellar asteroid `OumuamuaThis artist’s impression shows the first interstellar asteroid: `Oumuamua. This unique object was discovered on 19 October 2017 by the Pan-STARRS 1 telescope in Hawai`i. Subsequent observations from ESO’s Very Large Telescope in Chile and other observatories around the world show that it was travelling through space for millions of years before its chance encounter with our star system. `Oumuamua seems to be a dark red highly-elongated metallic or rocky object, about 400 metres long, and is unlike anything normally found in the Solar System.https://asteroidiedintorni.blog/wp-content/uploads/2017/10/lightcurve_oumuamua.jpgLightcurve_Oumuamuahttps://asteroidiedintorni.blog/wp-content/uploads/2017/10/1i_oumuamua_1910_01.png1I_Oumuamua_1910_01https://asteroidiedintorni.blog/wp-content/uploads/2017/10/radiante_a2017u1_marked.jpgRadiante_A2017U1_markedhttps://asteroidiedintorni.blog/wp-content/uploads/2017/10/find_orb_a2017u1.jpgFind_Orb_A2017U1https://asteroidiedintorni.blog/wp-content/uploads/2017/10/c2017u1_panstarrs.jpgC2017U1_PanStarrs2017-11-21T08:39:36+00:00monthlyhttps://asteroidiedintorni.blog/2017/11/05/gli-asteroidi-troiani/https://asteroidiedintorni.blog/wp-content/uploads/2017/11/punti-lagrangiani.jpgPunti Lagrangianihttps://asteroidiedintorni.blog/wp-content/uploads/2017/11/confronto-spettro-troiani-centauro.jpgConfronto spettro troiani centaurohttps://asteroidiedintorni.blog/wp-content/uploads/2017/11/mba_piano_eclittica.jpgMBA_piano_eclitticahttps://asteroidiedintorni.blog/wp-content/uploads/2017/11/mba_nord_eclittica.jpgMBA_nord_eclitticahttps://asteroidiedintorni.blog/wp-content/uploads/2017/11/patroclus.jpgPatroclus2017-11-05T13:50:03+00:00monthlyhttps://asteroidiedintorni.blog/2017/10/24/i-colori-degli-asteroidi/https://asteroidiedintorni.blog/wp-content/uploads/2017/10/color_indices_asteroids_tedesco2005.jpgColor_indices_asteroids_Tedesco2005https://asteroidiedintorni.blog/wp-content/uploads/2017/10/243_ida_nasa.jpg243_Ida_NASAhttps://asteroidiedintorni.blog/wp-content/uploads/2017/09/figura3.jpgFigura3https://asteroidiedintorni.blog/wp-content/uploads/2017/09/figura1.jpgFigura1https://asteroidiedintorni.blog/wp-content/uploads/2017/09/figura2.jpgFigura22017-10-24T19:11:45+00:00monthlyhttps://asteroidiedintorni.blog/2017/10/11/haumea-storia-personale-di-una-scoperta-scientifica/https://asteroidiedintorni.blog/wp-content/uploads/2017/10/haumea_orbit.jpgHaumea_orbithttps://asteroidiedintorni.blog/wp-content/uploads/2017/10/haumea_ring_from_surface_2.jpghaumea_ring_from_surface_2https://asteroidiedintorni.blog/wp-content/uploads/2017/10/haumea2.jpgHaumea2https://asteroidiedintorni.blog/wp-content/uploads/2017/09/2017-06-07303a-haumea-290.jpg2017-06-07303A-haumea 290https://asteroidiedintorni.blog/wp-content/uploads/2017/09/136108_haumea_pb.png(136108)_Haumea_(PB)https://asteroidiedintorni.blog/wp-content/uploads/2017/09/path-real-haumea-20170121.jpgpath-real-haumea-20170121https://asteroidiedintorni.blog/wp-content/uploads/2017/09/136108_haumea_lightcurve.png(136108)_Haumea_lightcurvehttps://asteroidiedintorni.blog/wp-content/uploads/2017/09/136108_haumea.png(136108)_Haumeahttps://asteroidiedintorni.blog/wp-content/uploads/2017/09/haumea_20170118_0231ut_60s.jpgHaumea_20170118_0231UT_60shttps://asteroidiedintorni.blog/wp-content/uploads/2017/09/haumea_nasa.jpghaumea_nasa2017-10-11T20:37:21+00:00monthlyhttps://asteroidiedintorni.blog/2017/09/15/loccultazione-di-tritone-del-5-ottobre-2017/https://asteroidiedintorni.blog/wp-content/uploads/2017/09/triton_occultation.jpgTriton_occultationhttps://asteroidiedintorni.blog/wp-content/uploads/2017/09/ucac4-410-143659.jpgUCAC4 410-143659https://asteroidiedintorni.blog/wp-content/uploads/2017/09/triton1_br.jpgTriton1_br2017-09-22T16:51:08+00:00monthlyhttps://asteroidiedintorni.blog/2017/09/22/comete-o-asteroidi/https://asteroidiedintorni.blog/wp-content/uploads/2017/09/heic1715b.jpgImage of binary asteroid system 288PThis set of images from the ESA/NASA Hubble Space Telescope reveals two asteroids with comet-like features orbiting each other. These include a bright halo of material, called a coma, and a long tail of dust. The asteroid pair, called 288P, was observed in September 2016 just before the asteroid made its closest approach to the Sun. These images reveal ongoing activity in the binary system. The apparent movement of the tail is a projection effect due to the relative alignment between the Sun, Earth, and 288P changing between observations. The tail orientation is also affected by a change in the particle size. Initially, the tail was pointing towards the direction where comparatively large dust particles (about 1 millimetre in size) were emitted in late July. However, from 20 September 2016 onwards, the tail began to point in the opposite direction from the Sun where small particles (about 10 microns in size) are blown away from the nucleus by radiation pressure.https://asteroidiedintorni.blog/wp-content/uploads/2017/09/figura1a.jpgFigura1a2017-09-26T15:34:49+00:00monthlyhttps://asteroidiedintorni.blog/2017/08/30/florence-sfiora-la-terra/https://asteroidiedintorni.blog/wp-content/uploads/2017/08/mappa_20170831_3122florence_large.jpgMappa_20170831_3122Florence_largehttps://asteroidiedintorni.blog/wp-content/uploads/2017/08/mappa_20170831_3122florence.jpgMappa_20170831_3122Florencehttps://asteroidiedintorni.blog/wp-content/uploads/2017/08/sky_3122florence.jpgSky_3122Florencehttps://asteroidiedintorni.blog/wp-content/uploads/2017/08/orbita_3122florence_b.jpgOrbita_3122Florence_bhttps://asteroidiedintorni.blog/wp-content/uploads/2017/08/orbita_3122florence.jpgOrbita_3122Florence2017-08-30T17:41:58+00:00monthlyhttps://asteroidiedintorni.blog/2017/08/22/il-follow-up-dei-neo/2017-08-22T14:05:48+00:00monthlyhttps://asteroidiedintorni.blog/2017/08/12/lasteroide-near-earth-2011-uw158/https://asteroidiedintorni.blog/wp-content/uploads/2017/08/2011uw158.jpg2011UW1582017-08-12T18:20:26+00:00monthlyhttps://asteroidiedintorni.blog/2017/07/31/2012-tc4-colpira-la-terra-ad-ottobre/https://asteroidiedintorni.blog/wp-content/uploads/2017/07/asteroidi_virtuali_2012tc4.jpgAsteroidi_virtuali_2012TC4https://asteroidiedintorni.blog/wp-content/uploads/2017/07/nube_asteroidi_virtuali_2012tc4.jpgNube_asteroidi_virtuali_2012TC4https://asteroidiedintorni.blog/wp-content/uploads/2017/07/2012tc4_20171012_earth_flyby.jpg2012TC4_20171012_Earth_flyby2017-08-07T09:24:40+00:00monthlyhttps://asteroidiedintorni.blog/2017/07/29/le-famiglie-di-asteroidi/https://asteroidiedintorni.blog/wp-content/uploads/2017/07/famiglie_di_asteroidi.jpgFamiglie_di_asteroidi2017-07-29T19:58:54+00:00monthlyhttps://asteroidiedintorni.blog/2017/07/18/asteroidi-di-classe-tunguska/https://asteroidiedintorni.blog/wp-content/uploads/2017/07/image2.jpgImage22017-07-18T20:29:03+00:00monthlyhttps://asteroidiedintorni.blog/alla-ricerca-degli-asteroidi-stazionari/2017-07-18T13:52:19+00:00weekly0.6https://asteroidiedintorni.blog/2017/07/11/primo-articolo-del-blog/https://asteroidiedintorni.blog/wp-content/uploads/2017/07/pexels-photo-30732.jpgPlaceholder Image2018-02-22T13:38:50+00:00monthlyhttps://asteroidiedintorni.blogdaily1.02026-03-22T16:32:02+00:00
