The NASA / ESA Hubble Space Telescope celebrates its 28th Anniversary Image of the Lagoon Nebula 4,000 light-years from Earth with this breathtaking and colorful space. 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 capabilities. The reason why you can see more stars is because Infrared is able to penetrate the dust and gas clouds to show 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, which some claim to look 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 it does not behave like any other star that dimms and lightens sporadically. Dust around the star, pictured here in an artist's picture, may be the most likely cause of his strange behavior.
This inner crater of a Martian crater has several of the seasonal dark stripes called "recurring drop lines" or RSL. that a report from November 2017 is interpreted as a grainy stream and does not become darker by the flow of water. The image comes from the HiRISE camera on NASA's Mars Reconnaissance Orbiter.

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 is evidence that there is an ocean under its frozen crust that can absorb 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 image of the side of Europe that faces Jupiter.
This fog or gas and dust cloud is called 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 is in the constellation Vela in the southern sky. The name means "sail of a ship" in Latin.
