NASA’s Hubble Space Telescope has successfully captured the latest image of the dwarf galaxy NGC 1705, located in the Easel constellation about 17 million light-years from Earth. In the new image, the dwarf galaxy shines in a bright red glow. The tiny, irregularly shaped galaxy has been described by the European Space Agency (ESA) as a “cosmic weirdo”.
ESA informs that NGC 1705 has recently experienced a “starburst” phase, meaning it is experiencing a typically high rate of star formation. In the image, the dwarf galaxy is surrounded by red cosmic “clouds” highlighted by bright starlight. The European Space Agency believes that NGC 1705 and other similar dwarf galaxies can now provide valuable insights into the overall evolution of galaxies.
In addition, the space agency explained that irregular dwarf galaxies like NGC 1705 contain fewer elements than larger galaxies, consisting mostly of hydrogen and helium. Therefore, they are thought to be similar to the earliest galaxies in the universe.
At the same time, it is worth mentioning that the Hubble Telescope is one of the most advanced telescopes available to scientists. Notably, Hubble took a picture of NGC 1705 in 1999, when astronomers used the telescope’s camera (then the Wide Field Planetary Camera 2) to look at the galaxy’s center. Now, scientists believe that new observations on Hubble, using much newer technology, can provide more detail and a more complete look at the Milky Way.
In December 2021, NASA, ESA and the Canadian Space Agency (CSA) also jointly launched the James Webb Space Telescope, which has higher infrared resolution and higher sensitivity than Hubble, It is expected to eventually replace the Hubble Telescope.
