A new SPHERE / VLT image of Hygiea, which could be the smallest dwarf planet in the solar system. As an object in the main asteroid belt, Hygiea immediately meets three of the four requirements to be classified as a dwarf planet: orbit around the Sun, it is not a moon and, unlike a planet, has not cleaned up the neighborhood around its orbit. The final requirement is that it has sufficient mass that its own gravity pulls it into an approximately spherical shape. This is what VLT observations have now revealed about Hygiea.

The dust around the star, represented here in an artist’s illustration, may be the most likely cause of his strange behavior.

NASA / ESA’s Hubble Space Telescope celebrates its 28th anniversary in space with this extraordinary and colorful image of the lagoon nebula 4000 light years from Earth. While the entire nebula is 55 light years wide, this image only reveals a portion of about four light years.
This is a more star-filled view of the Lagoon Nebula, using Hubble’s infrared capabilities. The reason you can see more stars is because infrared is capable of cutting dust and gas clouds to reveal the abundance of both young stars within the nebula, as well as more distant stars in the background.
The Rosette Nebula is located 5,000 light years from Earth. The distinctive nebula, which some claim is more like a skull, has a hole in the middle that creates the illusion of its rose-like shape.

La luna ghiacciata Europa di Giove potrebbe essere il posto migliore nel sistema solare per cercare la vita extraterrestre, secondo la NASA. La luna ha circa le dimensioni della luna terrestre e ci sono prove che ha un oceano sotto la sua crosta ghiacciata che può contenere il doppio dell’acqua rispetto alla Terra. Il budget 2016 della NASA include una richiesta di $ 30 milioni per pianificare una missione per indagare su Europa. L’immagine sopra è stata presa dal veicolo spaziale Galileo il 25 novembre 1999. È un mosaico di 12 cornici ed è considerata la migliore immagine del lato di Europa che si trova di fronte a Giove.
Questa nebulosa, o nuvola di gas e polvere, è chiamata RCW 34 o Gum 19. Le aree più luminose che puoi vedere sono dove il gas viene riscaldato da giovani stelle. Alla fine il gas è esploso come champagne dopo aver stappato una bottiglia. Gli scienziati chiamano questo flusso di champagne. Questa nuova immagine della nebulosa è stata catturata dal Very Large Telescope dell’Organizzazione spaziale europea in Cile. RCW 34 è nella costellazione di Vela nel cielo meridionale. Il nome significa “vele di una nave” in latino.
Il telescopio spaziale Hubble ha catturato immagini delle tre grandi lune di Giove – Io, Callisto ed Europa – che passavano contemporaneamente.
Usando potenti ottiche, gli astronomi hanno trovato un corpo simile a un pianeta, J1407b, con anelli 200 volte più grandi di quelli di Saturno. Questa è la rappresentazione di un artista degli anelli del pianeta J1407b, che stanno eclissando una stella.
Una macchia di stelle sembra mancare in questa immagine dall’Osservatorio di La Silla in Cile. Ma le stelle sono in realtà ancora lì dietro una nuvola di gas e polvere chiamata Lynds Dark Nebula 483. La nuvola è a circa 700 anni luce dalla Terra nella costellazione dei Serpenti (Il Serpente).
Questa è la più grande immagine del telescopio spaziale Hubble mai assemblata. È una parte della galassia della porta accanto, Andromeda (M31).
La NASA ha catturato una straordinaria nuova immagine dei cosiddetti “pilastri della creazione”, una delle scoperte più iconiche dell’agenzia spaziale. Le gigantesche colonne di gas freddo, in una piccola regione della Nebulosa Aquila, furono rese popolari da un’immagine simile presa dal telescopio spaziale Hubble nel 1995.
Gli astronomi che usano lo spazio Hubble hanno messo insieme questa immagine che mostra una piccola sezione dello spazio nella costellazione dell’emisfero sud Fornax. All’interno di questa immagine dello spazio profondo ci sono 10.000 galassie, che risalgono nel tempo a poche centinaia di milioni di anni dopo il Big Bang.
La nebulosa planetaria Abell 33 appare simile ad un anello in questa immagine, presa usando il Very Large Telescope dell’Osservatorio europeo meridionale. La bolla blu è stata creata quando una stella invecchiata ha sparso i suoi strati esterni e una stella in primo piano si è allineata con essa per creare un effetto “anello di fidanzamento con diamante”.
Questa immagine di Hubble sembra un marmo fluttuante o un occhio forse disincarnato. Ma in realtà è una nebulosa con al centro una stella gigante. Gli scienziati pensano che la stella fosse 20 volte più massiccia del nostro sole, ma sta morendo ed è destinata a diventare supernova.
Immagine composita di B14-65666 che mostra le distribuzioni di polvere (rosso), ossigeno (verde) e carbonio (blu), osservate da ALMA e stelle (bianche) osservate dal telescopio spaziale Hubble.
L’impressione dell’artista delle galassie in fusione B14-65666 si trova a 13 miliardi di anni luce di distanza.
