A new SPHERE / VLT image of Hygiea, the smallest dwarf planet in the solar system. As an object in the main asteroid belt, Hygiea immediately fulfills three of the four requirements in order to be classified as a dwarf planet: it orbits the sun, is not a moon and, unlike a planet, has not cleared its surroundings in orbit. The final requirement is that it have enough mass that its own gravity pulls it into an approximately spherical shape. This is what VLT observations have now revealed about Hygiea.

The exo-asteroid was probably drawn into our solar system from another star system 4.5 billion years ago. It was then in a declining orbit around Jupiter.

A close look at the diamond matrix of a meteorite that landed in Sudan in 2008. This is considered the first evidence of a protoplanet that has contributed to the formation of the Earth’s planets in our solar system.

2004 EW95 is the first carbon-rich asteroid, the existence of which has been confirmed in the Kuiper belt, and a relic of the original solar system.

The NASA / ESA Hubble Space Telescope is celebrating its 28th anniversary in space with this stunning and colorful image of the Lagoon Nebula, which is 4,000 light years from Earth. While the entire nebula has a diameter of 55 light years, this picture shows only a part of about four light years.

This is a more star-rich view of the Lagoon Nebula with Hubble’s infrared features. The reason why you can see more stars is because infrared can cut through the dust and gas clouds to see the abundance of both young stars in the nebula and more distant stars in the background.

The rosette nebula is 5,000 light years from Earth. The striking fog, which some claim to look more like a skull, has a hole in the middle that creates the illusion of its pink shape.

This inner slope of a Martian crater features several of the seasonal dark streaks called “recurring slope lines” (RSL), which are interpreted in a November 2017 report as granular currents rather than darkening due to running water. The image is from the HiRISE camera on NASA’s Mars Reconnaissance Orbiter.

The blue represents the gas of the Orion Nebula. This image is a compilation of observations from the Robert C. Byrd Green Bank telescope and NASA’s wide-field infrared survey telescope. “We still don’t understand in detail how large gas clouds collapse in our galaxy to form new stars,” said Rachel Friesen, one of the collaboration’s co-principal investigators. “But ammonia is an excellent indicator of dense, star-forming gas.”

This is what Earth and Moon look like from Mars. The image is made up of the best Earth image and the best moon image, taken on November 20, 2016 by NASA’s Mars Reconnaissance Orbiter. The orbiter’s camera takes pictures in three wavelength bands: infrared, red and teal. Mars was approximately 127 million miles from Earth when the images were taken.

Venus, bottom, and Jupiter shine brightly above Matthews, North Carolina, on Monday, June 29. The apparent close encounter, called a conjunction, has been giving a dazzling display in the summer sky. Although the two planets appear to be close together, in reality they are millions of miles apart.

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.

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.
