Equipped with space for 20 oz of joe, this mug will display two different images depending on temperature. When cold, it will feature red supergiant V838 Monocerotis, which is 20,000 light years from Earth on the edge of the Milky Way. When warm, a light echo of the star’s stellar outburst will appear.
The images featured on the mug were captured by the Hubble telescope in December 2002. It was revealed that V838 Monocerotis was 600,000 times brighter than the sun at its peak. However, simultaneously handling coffee and a significant astronomical event has its limits, and it this case that means the mug can’t enter the microwave or dishwasher.
