A new SPHERE / VLT image of Hygiea, which could be the smallest dwarf planet in the solar system to date. As an object in the main asteroid belt, Hygiea immediately meets three of the four conditions required to be classified as a dwarf planet: it orbits the Sun, it is not a moon and, unlike a planet , it did not erase the neighborhood from its orbit. The final requirement is that it has enough mass for its own gravity to pull it into a roughly spherical shape. This is what the VLT observations revealed about Hygiea.

Blue represents gas from the Orion Nebula. This image is a composite of the Robert C. Byrd Green Bank telescope and NASA’s Explore Wide-Area Infrared Telescope. “We still do not fully understand how large clouds of gas in our galaxy collapse to form new stars,” said Rachel Friesen, one of the collaboration’s co-principal investigators. “But ammonia is an excellent tracer of dense, starry gas. ”

NASA released the image for Halloween 2016 and played the theme in its press release. The agency said that “the macabre-looking object still had a pulse.” In the center of the crab nebula is the crushed nucleus, or “heart” of a burst star. The heart spins 30 times per second and produces a magnetic field that generates 1 trillion volts, said NASA.

Looking through the thick clouds of dust from the galactic bulge, an international team of astronomers revealed the unusual mixture of stars in the star cluster known as Terzan 5. New results indicate that Terzan 5 is one of the primordial building blocks of the bulge, most likely the relic of the very early days of the Milky Way.

Une nova classique se produit lorsqu’une étoile naine blanche gagne de la matière de son étoile secondaire (une naine rouge) sur une période de temps, provoquant une réaction thermonucléaire à la surface qui finit par éclater en une seule explosion visible. Cela crée une augmentation de 10 000 fois de la luminosité, représentée ici dans le rendu d’un artiste.

Bien que les deux planètes semblent être proches l’une de l’autre, elles sont en réalité à des millions de kilomètres l’une de l’autre.

Selon la NASA, la lune glacée Europa de Jupiter est peut-être le meilleur endroit du système solaire pour rechercher la vie extraterrestre. La lune a à peu près la taille de la lune terrestre, et il y a des preuves qu’elle a un océan sous sa croûte gelée qui peut contenir deux fois plus d’eau que la Terre. Le budget 2016 de la NASA comprend une demande de 30 millions de dollars pour planifier une mission d’enquête sur Europa. L’image ci-dessus a été prise par le vaisseau spatial Galileo le 25 novembre 1999. C’est une mosaïque de 12 images et est considérée comme la meilleure image à ce jour du côté d’Europa qui fait face à Jupiter.

Cette nébuleuse, ou nuage de gaz et de poussière, s’appelle RCW 34 ou Gum 19. Les zones les plus lumineuses que vous pouvez voir sont celles où le gaz est chauffé par les jeunes étoiles. Finalement, le gaz a éclaté comme du champagne après qu’une bouteille ait été débouchée. Les scientifiques appellent ce flux de champagne. Cette nouvelle image de la nébuleuse a été capturée par le très grand télescope de l’Organisation spatiale européenne au Chili. RCW 34 est dans la constellation de Vela dans le ciel du sud.

This is the largest Hubble Space Telescope image ever assembled. It’s a portion of the galaxy next door, Andromeda (M31).

NASA has captured a stunning new image of the so-called « Pillars of Creation, » one of the space agency’s most iconic discoveries. The giant columns of cold gas, in a small region of the Eagle Nebula, were popularized by a similar image taken by the Hubble Space Telescope in 1995.

Astronomers using the Hubble Space pieced together this picture that shows a small section of space in the southern-hemisphere constellation Fornax. Within this deep-space image are 10,000 galaxies, going back in time as far as a few hundred million years after the Big Bang.

Planetary nebula Abell 33 appears ring-like in this image, taken using the European Southern Observatory’s Very Large Telescope. The blue bubble was created when an aging star shed its outer layers and a star in the foreground happened to align with it to create a « diamond engagement ring » effect.

This Hubble image looks a floating marble or a maybe a giant, disembodied eye. But it’s actually a nebula with a giant star at its center. Scientists think the star used to be 20 times more massive than our sun, but it’s dying and is destined to go supernova.
