In this illustration, an asteroid (bottom left) breaks apart under the powerful gravity of LSPM J0207 + 3331, the oldest, coldest white dwarf known to be surrounded by a ring of dusty debris. Scientists think the system's infrared signal is best explained by two distinct rings composed of dust supplied by the crumbling asteroids

How did the massive black holes form in the early universe? The rotating gaseous disk of this dark matter halo breaks apart into three clumps that collapse under their own gravity to form supermassive stars.

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

2004 EW95 is the first carbon-rich asteroid to be found in the Kuiper Belt and a relic of the primordial solar system. This curious object is probably formed in the asteroid belt between Mars and Jupiter before being flown by billions of miles to its current home in the Kuiper Belt.
The NASA / ESA Hubble Space Telescope celebrates its 28th anniversary in space with this stunning and colorful image of the Nebula Lagoon 4,000 light-years from Earth. While the whole nebula is 55 light-years across, this image only reveals a portion of about four light-years.
This is a more star-filled view of the Nebula Lagoon using Hubble's infrared capabilities. The reason you can see more stars is because infrared is able to cut through the dust and gas clouds to reveal the abundance of both young stars within the nebula, as well as more distant stars in the background.
The Rosette Nebula is 5,000 light-years from Earth. The distinctive nebula, which some claim looks more like a skull, has a hole in the middle that creates the illusion of its rose-like shape.
KIC 8462852, also known as Boyajian's Star or Tabby's Star, is 1,000 light-years from us. It's 50% bigger than our sun and 1,000 degrees hotter. And it does not behave like any other star, dimming and brightening sporadically.
This inner slope of a Martian crater has several of the seasonal dark streaks called recurrent slope lineae, or RSL, that November 2017 report interprets as granular flows rather than darkening due to flowing water. The image is from the HiRISE camera on NASA's Mars Reconnaissance Orbiter.
This artist's impression shows a supernova explosion, which contains the luminosity of 100 million suns. Supernova iPTF14hls, which has exploded multiple times, may be the most massive and longest-ever ever observed.
This illustration shows hydrocarbon compounds splitting into carbon and hydrogen inside ice giants, such as Neptune, turning into a "diamond (rain) shower."
This is a stellar nursery in Orion Nebula where stars are born. The red filament is a stretch of ammonia molecules measuring 50 light-years long. The blue represents the gas of the Orion Nebula. This image is a composite of observation from the Robert C. Byrd Green Bank Telescope and NASA's Wide Field Infrared Survey Explore telescope. "We still do not understand how big clouds of gas in our Galaxy collapse to form new stars," said Rachel Friesen, one of the co-chief investigators. "But ammonia is an excellent tracer of dense, star-forming gas."
This is what Earth and its moon look like from Mars. The image is a composite 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 images in three wavelength bands: infrared, red and blue-green.

NASA's Cassini Spacecraft took these images of the planet's mysterious hexagon-shaped jetstream in December 2016. The hexagon was discovered in images taken by the spacecraft Voyager in the early 1980s.
A dead star gives off a greenish glow in this Hubble Space Telescope image of the Crab Nebula, located about 6,500 light years from Earth in the Taurus constellation. NASA released the image for Halloween 2016 and played the theme in its press release. The agency said the "ghoulish-looking object still has a pulse." At the center of the Crab Nebula is the crushed core, or "heart" of an exploded star. The heart is spinning 30 times per second and producing a magnetic field that generates 1 trillion volts, NASA said.
Peering through the thick dust clouds of the galactic bulge, an international team of astronomers revealed the unusual mix of stars in the stellar cluster known as Terzan 5. The new results indicate that Terzan 5 is one of the bulge's primordial building blocks, most probably the relic of the very early days of the Milky Way.

Say hello to dark galaxy Dragonfly 44. Like our Milky Way, it has a halo of spherical clusters of stars around its core.
A classical nova occurs when a white dwarf star gains from its secondary star (a red dwarf) over a period of time, causing a thermonuclear reaction on the surface that eventually erupts into a single visible outburst. This creates a 10,000-fold increase in brightness, depicted here in an artist's rendering
Gravitational lensing and space warping are visible in this image of nearby and distant galaxies captured by Hubble.

Meet UGC 1382: What astronomers thought was a normal elliptical galaxy (left) was actually revealed to be a massive disc galaxy made up of different parts when viewed with ultraviolet and deep optical data (center and right). 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 the Crab Nebula and its "beating heart," which is a neutron star in the right of the two bright stars in the center of this image. The neutron star pulses 30 times a second. The rainbow colors are visible due to the movement of the materials in the nebula occurring during the time lapse of the image.

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 that it has an ocean beneath its frozen crust that can hold twice as much water as Earth. NASA's 2016 budget includes a request for $ 30 million to plan a mission to investigate Europe. The image above was taken by the Galileo spacecraft on November 25, 1999. It is a 12-frame mosaic and is considered the best image of the side of Europe 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 a 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 Hubble Space Telescope captured images of Jupiter's three great moons – Io, Callisto, and Europa – passing by at once

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