A new SPHERE / VLT image of Hygiea, which may 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: it orbits the Sun, it is not a moon and, unlike a planet, it has not cleared the neighborhood around its orbit. The final requirement is that it has enough mass for its own gravity to drag it into a roughly spherical shape. This is what the VLT observations have now revealed about Hygiea.

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

Jupiter’s icy moon Europa may be the best place in the solar system to look for extraterrestrial life, according to NASA. The moon is about the size of Earth’s moon, and there is evidence it has an ocean beneath its frozen crust that may hold twice as much water as Earth. NASA’s 2016 budget includes a request for $30 million to plan a mission to investigate Europa. The image above was taken by the Galileo spacecraft on November 25, 1999. It’s a 12-frame mosaic and is considered the the best image yet of the side of Europa that faces Jupiter.

This nebula, or cloud of gas and dust, is called RCW 34 or Gum 19. The brightest areas you can see are where the gas is being heated by young stars. Eventually the gas burst outward like champagne after a bottle is uncorked. Scientists call this champagne flow. This new image of the nebula was captured by the European Space Organization’s Very Large Telescope in Chile. RCW 34 is in the constellation Vela in the southern sky. The name means “sails of a ship” in Latin.

The Hubble Space Telescope captured images of Jupiter’s three great moons — Io, Callisto, and Europa — passing by at once.

Using powerful optics, astronomers have found a planet-like body, J1407b, with rings 200 times the size of Saturn’s. This is an artist’s depiction of the rings of planet J1407b, which are eclipsing a star.

A patch of stars appears to be missing in this image from the La Silla Observatory in Chile. But the stars are actually still there behind a cloud of gas and dust called Lynds Dark Nebula 483. The cloud is about 700 light years from Earth in the constellation Serpens (The Serpent).

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.
