One of the brightest planetary nebulae in the sky, first discovered in 1878, is the NGC 7027 in the direction of the constellation of the swan.

The Asteroid 6478 Gault, with the NASA / ESA Displacement Space Telescope, sees two narrow, cometary tails of debris telling us that the asteroid is slowly self-destructing. The bright stripes around the asteroid are background stars. The Gault asteroid is located 21

4 million kilometers from the Sun, between the orbits of Mars and Jupiter.

The ghostly shell in this image is a supernova, and the glowing trail that leads away from it is a pulsar.

Hidden This cosmic bat, one of the darkest corners of the Orion constellation, spreads its blurred wings through the interstellar space two thousand light-years away. It is illuminated by the young stars that are in its core – although they are enveloped in opaque dust clouds, their bright rays still illuminate the fog.

In this illustration, several dust rings orbiting the sun. These rings form when the gravitational pull of the planet pulls dust grains into orbit around the sun. Scientists recently discovered Mercury's dust orbit in orbit. Others suggest that the source of the dust ring of Venus is a group of asteroids that had never been discovered before.

This is the impression of an artist of spherical star clusters surrounding the Milky Way galaxy.

A radio image of hydrogen gas in the small Magellanic cloud. Astronomers believe that the dwarf galaxy is slowly dying and will ultimately be consumed by the Milky Way.

Further evidence of a supermassive black hole in the center of the Milky Way has been found. In this visualization, data from simulations of orbital motion of gas are used, which spin in a circular orbit around the black hole at about 30% of the speed of light.

Does that look like a bat to you? This huge shadow comes from a bright star, which reflects against the dusty disk that surrounds it. Hey, Bennu! NASA's OSIRIS-REx mission, which heads to the primitive asteroid Bennu, sends back images that are nearing its December 3 goal.

These three panels show a supernova before, during and after their occurrence 920 million light. Years from Earth (from left to right). The supernova, called iPTF14gqr, is unusual because the star was massive, but its explosion quickly and fainted. The researchers believe that this is due to a companion star that has sucked its mass away.

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

This is a more star-filled view of the Lagoon Nebula using Hubble's infrared functions. The reason why you can see more stars is because Infrared is able to penetrate the dust and gas clouds to reveal the fullness of the two young stars in the fog and distant stars in the background.

The Rosette Nebula is 5,000 light-years from Earth. The distinctive mist, some of which claim that it looks more like a skull, has a hole in the middle that creates the illusion of its rosette-like shape.

KIC 8462852, also known as Boyajian's Star or Tabby's Star, is 1,000 light-years away from us. It is 50% larger than our sun and 1,000 degrees hotter. And he does not behave like any other star that dims and lightens sporadically. Dust around the star, pictured here in an artist's image, may be the most likely cause of his strange behavior.

Jupiter's icy moon According to NASA, Europe is the best place in the solar system to search for extraterrestrial life. The moon is about the size of the earth's moon, and there are signs that beneath its frozen crust there is an ocean that can contain twice as much water as the earth. NASA's budget for 2016 includes a $ 30 million request to plan a mission to investigate Europe. The picture above was taken on 25th November 1999 by the Galileo probe. It is a 12-frame mosaic and is considered to be the best picture of Jupiter's side facing Europe.

This mist or gas and dust cloud is referred to as RCW 34 or chewing gum 19. The brightest areas you can see are the areas where the gas is heated by young stars. Finally, the gas burst like champagne after a bottle has been uncorked. Scientists call this champagne flow. This new image of the nebula was taken by the Very Large Telescope of the European Space Agency in Chile. RCW 34 stands in the constellation Vela in the southern sky. The name means "sail of a ship" in Latin.
