Hubble takes a giant image of the Triangular Galaxy



This gigantic image of the Triangular Galaxy - also known as Messier 33 - is a composition of about 54 different points with Hubble's Advanced Camera for Surveys. With an impressive size of 34,372 times 19,365 pixels, it is the second largest image ever released by Hubble. It is only diminished by the image of the Andromeda galaxy, launched in 2015. The mosaic of the Triangular Galaxy shows the central region of the galaxy and its inner spiral arms. Millions of stars, hundreds of clusters of stars and bright nebulae are visible. This image is too large to be easily displayed at full resolution and is best enjoyed using the zoom tool. Credit: NASA, ESA and M. Durbin, J. Dalcanton and B. F. Williams (University of Washington)

The NASA / ESA Hubble Space Telescope captured the most detailed image of a nearby neighbor of the Milky Way – the Triangular Galaxy, a spiral galaxy located only three million light-years away. This panoramic survey of the third largest galaxy in our Local Group of Galaxies provides a mesmerizing insight into the 40 billion stars that make up one of the most distant objects visible to the naked eye.

This new image of the Triangular Galaxy – also known as Messier 33 or NGC 598 – has an impressive 665 million pixels and shows the central region of the galaxy and its inner spiral arms. To unite this gigantic mosaic, the Hubble Advanced Research Camera needed to create 54 separate images.

Under excellent dark sky conditions, the Triangular Galaxy can be seen with the naked eye as a faint, blurred object in the Triangulum (Triangle) constellation, where its ethereal glow is an exciting target for amateur astronomers.

Just three million light years from Earth, the Triangular Galaxy is a notable member of the Local Group – it is the group's third largest galaxy, but also the smallest spiral galaxy in the group. [1]. It measures only about 60,000 light years, compared to the 200,000 light-years of the Andromeda galaxy; the Milky Way is between these extremes at about 100,000 light-years in diameter.

Not only is the Triangular Galaxy outdated in size by the other two spirals, but by the multitude of stars they contain. The Triangular Galaxy has at least one order of magnitude less stars than the Milky Way and two orders of magnitude less than Andromeda. These numbers are difficult to understand when already in this picture 10 to 15 million individual stars are visible.

In contrast to the two larger spirals, the Triangular Galaxy does not have a bright protuberance in the center and also does not have a bar that connects its spiral arms to the center. It contains, however, an enormous amount of gas and dust, giving rise to the rapid formation of stars. New stars form at a rate of approximately one solar mass every two years.

The abundance of gas clouds in the Triangular Galaxy is precisely what attracted astronomers to conduct this detailed research. When stars are born, they use material in those clouds of gas and dust, leaving less fuel for new stars to emerge. The Hubble image shows two of the four brightest regions in the galaxy: NGC 595 and NGC 604. The latter is the second most luminous region of ionized hydrogen within the Local Group and is also among the largest known star formation regions Group.

These detailed observations of the Triangular Galaxy have a tremendous legacy value – combined with those of the Milky Way, the Andromeda Galaxy and the irregular Magellan Cloud galaxies that will help astronomers better understand star formation and stellar evolution.

This image shows the NGC 604, located inside the Triangular Galaxy. With about 1,500 light-years in diameter, this is one of the largest and brightest concentrations of ionized hydrogen (H II) in our Local Group of Galaxies, and is an important center of star formation. The gas in NGC 604, about nine-tenths of which is hydrogen, is gradually collapsing under the force of gravity to create new stars. Once these stars have formed, the energetic ultraviolet radiation they emit excites the remaining gas in the cloud. This image is only a small part of the large wide field image of the Triangular Galaxy created by the NASA / ESA Hubble Space Telescope. Hubble has observed this object before, with different cameras: In 2003, using WFPC2 and in 2010, using ACS. The different colors in the images have their origin in the different filters that are being used. Credit: NASA, ESA and M. Durbin, J.
