This illustration shows the core of a star, known as a white dwarf, placed in orbit around a black hole. During each orbit, the black hole snatches more material from the star and pulls it into a bright disc of material around the black hole. Prior to his encounter with the black hole, the star was a red giant in the later stages of stellar evolution.
This artist’s illustration shows the collision of two 125-mile-wide dusty and dusty bodies that orbit the bright star Fomalhaut, located 25 light years away. It was once thought that observation of the consequences of this collision was an exoplanet.

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.

Comparison of GJ 3512 with the Solar System and other nearby red dwarf planetary systems. The planets around a solar mass star can grow until they start accumulating gas and become giant planets like Jupiter in a few million years.

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

These negative images of 2015 BZ509, circled in yellow, show the first known interstellar object that became a permanent part of our solar system. The ex-asteroid was probably attracted to our solar system by another stellar system 4.5 billion years ago. He then settled in a retrograde orbit around Jupiter.

2004 EW95 is the first carbon-rich asteroid to be confirmed to exist in the Kuiper belt and a relic of the primordial solar system. This curious object probably formed in the asteroid belt between Mars and Jupiter before being launched billions of miles from its current location in the Kuiper Belt.
NASA / ESA’s Hubble Space Telescope celebrates its 28th anniversary in space with this extraordinary and colorful image of the Lagoon Nebula 4,000 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 the most 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.
This internal slope of a Martian crater has some of the seasonal dark stripes called “recurrent slope line”, or RSL, which a November 2017 report interprets as granular flows, rather than obscuring due to flowing water. The image comes from the HiRISE camera on NASA’s Mars Reconnaissance Orbiter.

This extraordinary image is the stellar nursery of the Orion Nebula, where the stars are born. The red filament is a stretch of ammonia molecules that measure 50 light years. Blue represents the gas of the Orion nebula. This image is an observation composite of the Robert C. Byrd Green Bank Telescope and NASA’s wide-field infrared exploration telescope. “We still don’t understand in detail how large clouds of gas in our Galaxy collapse to form new stars,” said Rachel Friesen, one of the principal investigators of the collaboration. “But ammonia is an excellent dense gas tracer that forms stars.”
Here’s what the Earth and its moon looks like from Mars. The image is a composite of the best Earth image and the best lunar image taken on November 20, 2016 by NASA’s Mars Reconnaissance Orbiter. The orbiter’s camera takes images in three wavelength bands: infrared, red and blue-green. Mars was about 127 million miles from Earth when the pictures were taken.

A dead star gives off a greenish glow in this image of the Hubble Space Telescope of the Crab Nebula, located approximately 6,500 light years from Earth in the constellation of Taurus. NASA released the image for Halloween 2016 and picked up on the theme in its press release. The agency said that “the ghoulish-looking object still has an impulse.” At the center of the Crab Nebula is the flattened core, or “heart” of an exploded star. The heart rotates 30 times per second and produces a magnetic field that generates 1 trillion volts, NASA said.
Peering through the thick clouds of dust from the galactic bulge, an international team of astronomers has revealed the unusual mix of stars in the star cluster known as Terzan 5. The new findings indicate that Terzan 5 is one of the primordial blocks of the bulge, most likely the relic of the very first days of the Milky Way.

In una completa inversione della normale struttura della galassia, il centro è più giovane del suo disco a spirale esterno.
Il telescopio spaziale Hubble della NASA ha catturato questa immagine della Nebulosa del Granchio e del suo “cuore pulsante”, che è una stella di neutroni alla destra delle due stelle luminose al centro di questa immagine.

Il telescopio spaziale Hubble ha catturato l’immagine di una galassia nascosta più debole di Andromeda o della Via Lattea. Questa galassia a bassa luminosità superficiale, chiamata UGC 477, è distante oltre 110 milioni di anni luce nella costellazione dei Pesci.
Il 19 aprile, la NASA ha rilasciato nuove immagini di crateri luminosi su Cerere. Questa foto mostra il cratere Haulani, che mostra tracce di frane dal suo bordo. Gli scienziati ritengono che alcuni crateri sul pianeta nano siano luminosi perché sono relativamente nuovi.

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

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.
