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!

An image of galaxy cluster SDSS J1038+4849 captured by NASA’s Hubble Space Telescope appears to show a “happy face,” replete with two orange eyes, a white button nose and a smiling expression.

​Say cheese! Hubble telescope captures extraterrestrial smiley face

The galactic smiley can be seen in the photo of galaxy cluster SDSS J1038+4849. The picture was recently released by NASA after the cluster was spotted by amateur star gazer Judy Schmidt.

Its two bright glowing eyes are in fact separate galaxies, while the face and smile itself are distinct due to the celestial 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,” the Hubble website explains, citing Einstein’s theory of general relativity.
