It's a strange galaxy that Hubble just observed from what you can see in the main image captured by the telescope. In the picture, you can see the dwarf galaxy NGC 1705 (a tiny galaxy) that ESA (the European space agency) claimed to be a "cosmic oddball." The dwarf galaxy NGC 1705 is located "only" 17 million light-years from us in the constellation Pictor. And according to space agencies, the galaxy is a strange one. 

It is due to its irregular shape, rarely found in a galaxy and its tiny size. But these are just two reasons why it is thought to be "weird", the main reason being different. First of all, the image above shows the galaxy shining brighter than before, being covered by a huge cloud of light. It's not an explosion, it's just a starburst phase of the galaxy, which means an extremely high rate of star formation. 

That's why the European space agency sees it as rather strange, due to its small size, irregular shapes, and the phase the galaxy goes through. Rare are the moments when we catch a galaxy having such a phase of star creation at an extremely fast pace. 

However, irregularly shaped dwarf galaxies are different from "normal" galaxies because they contain fewer elements than "normal" galaxies. In addition, dwarf galaxies contain a lot of helium and oxygen, which is why scientists believe they are similar to the oldest galaxies in the universe. 

Hubble observed this galaxy in 1999 with its wide-field Planetary Camera 2, but now used Wide Field Camera 3 to observe it.
