• NASA’s Hubble Space Telescope captures an image of a pocketful of stars

    The NASA Hubble Space Telescope has once again captured an awe-inspiring image of our galaxy. The image in question shows the globular cluster NGC 1805, or ‘a pocketful of stars,’ as NASA describes it.

    The globular cluster is an extremely tight grouping of stars located near the edge of the Large Magellanic Cloud, a satellite galaxy of our own Milky Way. In the center of these cluster are stars which are 100 to 1,000 times closer to each other than the nearest stars are to our Sun, which means the chance of finding a planetary systems around them is highly unlikely.

    The wide variety of colours in this image is also a great example of the different types of stars we have in the universe. The blue stars seen in the image show nearly ultraviolet light, whereas the red stars show near-infrared and red light. This is especially important because ground-based observatories are unable to observe most of the ultraviolet light because it is absorbed by the atmosphere, meaning the only way to capture an image like this is to use a space-based telescopes like Hubble.

    Take a look at the image below:

    “Observing such clusters of stars can help astronomers understand how stars evolve, and what factors determine whether they end their lives as white dwarfs or explode as supernovae.” NASA explained in a statement.
