During each orbit, the black hole rips off more material from the star and pulls it into a glowing disk of material around the black hole. Before its meeting with the Black Hole, the star was a red giant in the final stages of stellar evolution.

A new SPHERE / VLT image of Hygiea, which may be the smallest dwarf planet in the solar system yet. 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 that its own weight pulls it into a rough spherical shape. This is what VLT observations have revealed about Hygiene.
This is an artist’s rendition of what a massive galaxy from the early universe might look like. The representation shows that the star formation in the galaxy ignites the surrounding gas.

Comparison of GJ 3512 with the solar system and other nearby planting systems with red dwarfs. Planets around a solar mass star can grow until they begin to take on gas and become giant planets like Jupiter in a few million years. But we thought that small stars like Proxima, TRAPPIST-1, the star of the Teegarder and GJ 3512, could not form Jupiter mass planets.

It is illuminated by the young stars embedded in their core – despite being enveloped by opaque clouds of dust, their bright rays still illuminate the nebula.
In this illustration, several ponds ring around the sun. These rings are formed when the gravitational forces of the planets pull dust grains in orbit around the sun.

These three panels reveal a supernova before, during and after it happened 920 million light years from Earth (from left to right). Supernova, called iPTF14gqr, is unusual because, although the star was massive, its explosion was rapid and weak. Scientists believe this is due to a companion who has stripped away its mass.

These negative images from the 2015 BZ509, which are circled in yellow, show the first known interstellar object that has become a permanent part of our solar system. The exo-asteroid was probably drawn into our solar system from another star system 4.5 billion years ago. It then settled into a retrograde orbit around Jupiter.

NASA / ESA Hubble Space Telescope celebrates 28th anniversary in space with this amazing and colorful image of Lagoon Nebula 4000 light years from Earth. While the entire nebula is 55 light years, this image reveals only part of about four light years.
This is a more star-filled view of the lagoon’s nebula, with Hubble’s infrared capabilities. The reason you can see more stars is because infrared can cut through dust and gas clouds to reveal the abundance of both young stars in the nebula, as well as more distant stars in the background.
The rosette nebula is 5,000 light-years from Earth. The distinct nebula, which some claim looks more like a skull, has a hole in the middle that creates an illusion of its rose-like shape.
This inner slope of a Martian crater has several of the seasonal dark streaks called “recurrent slope lineae,” or RSL, which a November 2017 report interprets as granular flows, rather than darker due to running water. The image is from the HiRISE camera on NASA’s Mars Reconnaissance Orbiter.

The blue represents the gas from Orion Nebula. This image is a composite of observations from the Robert C. Byrd Green Bank Telescope and NASA’s wide field Infrared Survey Explore telescope. “We still don’t understand in detail how large gas clouds in our galaxy collapse to form new stars,” said Rachel Friesen, one of the partners’ founding partners. “But ammonia is an excellent tracer of dense, star-forming gas.”
So the Earth and its moon look like Mars. The image is a composition 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 captures images in three wavelength bands: infrared, red and blue-green. March was about 127 million miles from Earth when the photos were taken.

A dead star emits a greenish glow in this Hubble Space Telescope image of Crab Nebula, located approximately 6,500 light-years from Earth in the constellation Taurus. NASA released the image for Halloween 2016 and featured the theme in its press release. The agency said that the “ghoulish-looking object still has a pulse.” In the center of the Crab Nebula is the crushed core, or “heart” of an exploded star. The heart spins 30 times per second, producing a magnetic field that generates 1 trillion volts, NASA said.
By looking through the thick clouds of dust from the galactic bay, an international team of astronomers revealed the unusual mixture of stars in the stellar cluster, known as Terzan 5. The new results indicate that Terzan 5 is one of the belly’s primary building blocks, probably the relic above the very early days on the Milky Way.

Say hello to the dark galaxy Dragonfly 44. Like our Milky Way, it has a halo of spherical clusters of stars around its core.
A classic nova occurs when a white dwarf star receives matter from its secondary star (a red dwarf) for a period of time, causing a thermonuclear reaction to the surface that eventually arises in a single visible eruption. This creates a 10,000-fold increase in brightness, which is shown here in an artist’s rendering.

In a complete reversal of normal galaxy structure, the center is younger than its outer spiral disk.
NASA’s Hubble Space Telescope captured this image of Crab Nebula and its “beating heart,” which is a neutron star to the right of the two bright stars in the center of this image. The neutron star pulses 30 times per second. The colors of the rainbow are visible due to the movement of material in the nebula which occurs during the time of the image.

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.

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.
