Wonders of the universe
The UAE plans to send a probe to Mars in 2020 -- -- the Arab world's first mission to another planet. More ambitious still, there are plans to develop a human settlement on Mars by 2117. The Emirates' space program is a bold move, joining a growing list of nations exploring our solar system and beyond.

This striking image is the stellar nursery in the 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 don't understand in detail how large clouds of gas 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."

See that tiny dot between Saturn's rings? That's Earth, as seen by the Cassini mission on April 12, 2017. "Cassini was 870 million miles away from Earth when the image was taken," according to NASA. "Although far too small to be visible in the image, the part of Earth facing Cassini at the time was the southern Atlantic Ocean." Much like the famous "pale blue dot" image captured by Voyager 1 in 1990, we are but a point of light when viewed from the furthest planet in the solar system.

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. The new results indicate that Terzan 5 is one of the bulge's primordial building blocks, most likely the relic of the very early days of the Milky Way.

A classical nova occurs when a white dwarf star gains matter from its secondary star (a red dwarf) over a period of time, causing a thermonuclear reaction on the surface that eventually erupts in a single visible outburst. This creates a 10,000-fold increase in brightness, depicted here in an artist's rendering.

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 at 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 materials in the nebula occurring during the time-lapse of the image.

An international team of astronomers may have discovered the biggest and brightest supernova ever. The explosion was 570 billion times brighter than the sun and 20 times brighter than all the stars in the Milky Way galaxy combined, according to a statement from The Ohio State University, which is leading the study. Scientists are straining to define the supernova's strength. This image shows an artist's impression of the supernova as it would appear from an exoplanet located about 10,000 light years away.

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.

A massive galaxy cluster known as SDSS J1038+4849 looks like a smiley face in an image captured by the Hubble Telescope. The two glowing eyes are actually two distant galaxies. And what of the smile and the round face? That's a result of what astronomers call "strong gravitational lensing." That happens because the gravitational pull between the two galaxy clusters is so strong it distorts time and space around them.

This long-exposure image from the Hubble Telescope is the deepest-ever picture taken of a cluster of galaxies. The cluster, called Abell 2744, contains several hundred galaxies as they looked 3.5 billion years ago; the more distant galaxies appear as they did more than 12 billion years ago, not long after the Big Bang.

Is that a giant hand waving at us? Actually, it's what's left of a star that died and exploded a long time ago. Astronomers nicknamed it the "Hand of God." NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, took this image in high-energy X-rays, shown in blue. The image was combined with images from another space telescope, the Chandra X-ray Observatory.

The Hubble Space Telescope captured this image of the Southern Pinwheel Galaxy, one of the largest and closest galaxies of its kind. The center of the galaxy is mysterious, researchers say, because it has a double nucleus -- a supermassive black hole that may be ringed by a lopsided disc of stars, giving it the appearance of a dual core.

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.
