Hovering happy face smiles down on us from space

This smiley face hovering in space looks like it was beamed into the heavens by a celestial keyboard. Captured by the Hubble Space Telescope, it was in fact created by a quirk of general relativity known as gravitational lensing.

The glowing eyes are bright galaxies that are part of a galaxy cluster known as SDSS J1038+4849. The massive structure warps space-time, bending light like a lens to create a stretched image of distant galaxies, called an Einstein ring. The well-positioned circular shape creates the outline of the face and the wry grin.

The happy face was uncovered by amateur astronomer Judy Schmidt in a similar image while hunting for submissions for the Hubble’s Hidden Treasures competition. Contestants were asked to search through the space telescope’s vast archives for overlooked discoveries.

Hubble Spies Cosmic Emoticon Smiling Back

As captured by the Hubble Space Telescope’s Wide Field and Planetary Camera 2 (WFPC2) and Wide Field Camera 3 (WFC3), this ‘cosmic smiley’ was created by the extreme gravitational environment surrounding the galactic cluster SDSS J1038+4849. Space-time is so warped around the mass of galaxies that light from behind the cluster is being bent and magnified as if through a vast cosmic lens. Learn more

Hubble Sees A Smiling Lens : In the center of this image, taken with the NASA/ESA Hubble Space Telescope, is the galaxy cluster SDSS J1038+4849 and it seems to be smiling.

You can make out its two orange eyes and white button nose. In the case of this happy face, the two eyes are very bright galaxies and the misleading smile lines are actually arcs caused by an effect known as strong gravitational lensing.

Galaxy clusters are the most massive structures in the Universe and exert such a powerful gravitational pull that they warp the spacetime around them and act as cosmic lenses which can magnify, distort and bend the light behind them. This phenomenon, crucial to many of Hubbles discoveries, can be explained by Einsteins theory of general relativity.

In this special case of gravitational lensing, a ring known as an Einstein Ring is produced from this bending of light, a consequence of the exact and symmetrical alignment of the source, lens and observer and resulting in the ring-like structure we see here.

Hubble has provided astronomers with the tools to probe these massive galaxies and model their lensing effects, allowing us to peer further into the early Universe than ever before. This object was studied by Hubbles Wide Field and Planetary Camera 2 as part of a survey of strong lenses.

A version of this image was entered into the Hubbles Hidden Treasures image processing competition by contestant Judy Schmidt.

If you’re happy and you know it, smile back: “Hubble Telescope Spots an Emoticon in Outer Space This new NASA image shows Hubble’s rendition of SDSS J1038+4849, a galaxy cluster in the constellation Ursa Major. The massive yellow galaxies making up the “eyes” of the imaginary face are in the foreground; their combined gravity is magnifying and distorting the light of much more distant background galaxies through a process known as ’strong gravitational lensing’. Lensing is a consequence of Einstein’s General Theory of Relativity, which treats space and time as two aspects of a fabric of the cosmos that can be stretched by the presence of a gravitational field. Purely by chance, the lensed arcs of the background galaxies frame the “face’ and form its smiling "mouth”.

ASPEN :: 4300-6163-4849 :: @uchibambi

today i took a trip to the lovely wintery town of aspen! i can only assume the dream address is still a work in progress but from what i saw, it’s beautiful regardless. as of right now, there are no hacks to be seen, but it still makes for a fun and very calming trip as well as giving me a big of inspiration! with lots of little presents scattered throughout, aspen is a town you won’t want to miss!

Happy Day!

Sometimes when I look up at the wonders of the night sky, it brings a smile to my face. Now I know that the Universe smiles back!

This is the galaxy cluster SDSS J1038+4849, some 7.5 billion light-years away, as seen by the Hubble Space Telescope. The apparition of the smiley face comes from a combination of actual objects and the effects of gravity. The two “eyes” are bright galaxieswithin the cluster, while the smiling mouth and the outlines of the face can be thought of as spatial special effects.

Galaxy clusters are massive structures, exerting a powerful gravitational pull in their vicinity. The effect is so strong that it actually warps the spacetime around them, creating a cosmic lens that magnifies, distorts and bends the light of distant objects behind them. This gravitational lensing can cause the viewer to see multiple images of a distant galaxy or smear their light, as seen here. The arcs in this image are known as Einstein Rings, created by a symmetrical alignment of the light source, the gravitational lens, and the observer.

Astronomers can use these cosmic magnifying lenses to see farther into the Universe than ever before. By making distant objects appear up to 10 times brighter than they would be without the intervening lens, researchers can see and study things that they could not observe with conventional methods. In October 2014, Hubble used a gravitational lens to spot one of the farthest, faintest and smallest galaxies ever seen, from a time when the Universe was just 3 percent of its current age (http://on.fb.me/1DTUMIp).

Sure, I know that seeing this smiling face is a case of pareidolia, with my brain seeing something recognizable in random visual cues. And I know that the cause of the cues in this image can be explained by Einstein’s theory of general relativity. But I don’t care about that right now, because the Universe is smiling at me.

Smiley face galaxy cluster spotted by Hubble Telescope

The Hubble space telescope snapped this picture of SDSS J1038+4849, a galaxy cluster that’s quite distant to the Earth. The two eyes are made of very bright galaxies, and the smile lines are caused by strong gravitational lensing that creates an arc-like effect.
