Time to change the desktop images. The Hubble Space Telescope has produced an amazing panoramic image of the Triangulum Galaxy, one of Earth's next galactic neighbors.
The famous space observatory captured a swirling spiral of stars in 54 fields of view and collected data over a period of approximately 19,000 light-years, Hubble researchers said in a statement. (A light-year is the distance that light travels in a year, about 6 trillion miles or 10 trillion kilometers.)
The result is a huge image of triangulum – also called M33 – that includes about 25 million visible stars. While the picture is a work of art in its own right, astronomers will use it to find out more about the neighborhood near the Milky Way, which is our own galaxy.
Triangulum is one of several near-Earth galaxies living in a zone known as the Local Group. The group has dozens of members, but is dominated by Andromeda's three major galaxies (which Hubble also shot in high resolution in 2015), the Milky Way and the Triangulum.
The star formation of Triangulum is about ten times more intense than what was recorded in Hubble's Andromeda image. Astronomers say the new image of triangulum will reveal some of the mechanisms of this star discovery.
"Astronomers believe that Triangulum in the Local Group was more introverted and isolated from the frequent interactions with other galaxies while simultaneously engaged in the production of stars along the organized spiral arms, the discovery of the history of the Triangulum galaxy be an important reference The researchers understand how galaxies evolve over time, and what different paths shape what we see today. "
Hubble has been in operation for nearly 30 years since its founding in 1990 and continues to be in excellent health. NASA said the operation should also go beyond the launch of the next-generation James Webb Space Telescope, which is currently scheduled for launch in 2021.
