Have Emoji’s started appearing in Space?

In the centre 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 Hubble   s discoveries, can be explained by Einstein   s 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 Hubble   s Wide Field and Planetary Camera 2 (WFPC2) and Wide  Field Camera 3 (WFC3) as part of a survey of strong lenses. A version of this image was entered into the Hubble   s Hidden Treasures image processing competition by contestant Judy Schmidt.

There’s no denying that Emoji’s have taken over the world, with everything from a dancing lady to a smiling poo now appearing in our text messages.

But now, it appears that they’ve made their way to space, after a galaxy cluster appeared in the shape of an emoji.

New images of the galaxy cluster SDSS J1038+4849 appear in the shape of a gigantic emoji smiling down on Earth.

The two ‘eyes’ are actually bright galaxies, while the ‘smile’ is an arc formed by strong gravitational lensing.

The gigantic galaxy clusters are the biggest structures in the entire universe. Their gravitational pull is so strong that they are capable of warping space around them, meaning that they can work as ‘cosmic lenses’, distorting light and causing the arc smile seen in the photo.

The unique picture was snapped by Judy Schmidt, an amateur astronomer who submitted the image to the Hubble Telescope’s Hidden Treasures competition.

Hubble was launched in in 1990, and has captured more than a million observations of space since then.
