A heliosphere is the bubble-like region of space, dominated by our sun, separating us from interstellar space. Solar wind creates and maintains this bubble against the outside pressure of the interstellar medium. Voyager 1 is the only manmade object to have made it through the bubble.
Now it's your chance to wear one of the greatest wonders of the universe on your denim jacket or back pack.
Helio patch is embroidered and 6 x 6cm (2.3 x 2.3 inches). It has an iron on backing, but I recommend you also give it a few stitches.
Please take time to read the terms of service before ordering.
