The NASA / ESA Hubble Space Telescope is celebrating its 28th anniversary in space with this stunning and colorful image of the Lagoon Nebula 4,000 light-years from Earth. While the whole nebula is 55 light-years across, this image only reveals a fraction 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 the 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 doesn't behave like any other star, dimming and brightening sporadically. Dust around the star, depicted here in an artist's illustration, may be the most likely cause of its strange behavior.
This inner slope of a Martian crater has several of the seasonal dark streaks called "recurrent slope lineae," or RSL, that a 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.

The blue represents the gas of the 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 the detail of how much gas clouds in our Galaxy collapse to form new stars," said Rachel Friesen, one of the collaboration's co-Principal Investigators. "But ammonia is an excellent tracer of dense, star-forming gas."

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 Voyager spacecraft in the early 1980s. It is estimated to have a diameter greater than two Earths.
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 constellation Taurus. NASA released the image for Halloween 2016 and played up 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.

In a complete reversal of the normal galaxy structure, the center is smaller 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 at the right of two bright stars in the center of this image. The neutron star pulses 30 times a second. Rainbow colors are visible due to the movement of materials in the nebula occurring during the time-lapse of the image.

Venus, bottom, and Jupiter shine brightly above Matthews, North Carolina, on Monday, June 29. The apparent close encounter, called 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 Europe 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 Europe. The image above was taken by Galileo spacecraft on November 25, 1999. It is a 12-frame mosaic and is considered the best image yet on 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 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 Europe – passing by at once.

Astronomers using the Hubble Space pieced together this picture to show 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 like a floating marble or 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 destined to go supernova.
