Hubble Space Telescope Snapped The Sharpest Image Of The Triangle Galaxy

Hubble Space Telescope Snapped The Sharpest Image Of The Triangle Galaxy

The NASA/ESA Hubble Space Telescope image of the Triangulum Galaxy, a spiral galaxy located at a distance of only three million light-years, inspires the question: "What incredible life forms reside there?"

NASA and ESA's Hubble Space Telescope recently obtained a breathtaking, incredibly detailed photo of the Triangulum Galaxy, a spiral galaxy that is a close neighbor of the Milky Way.

Weisz came to UC Berkeley in the summer of 2016 and focuses on stars, dark matter, and galaxies near Earth, in particular the Local Group of galaxies that includes some 100 mostly small galaxies surrounding the two heavies, our own Milky Way and Andromeda.

Under favorable conditions, the galaxy can be seen with the naked eye as a fuzzy object in the constellation of the Triangle.

The massive mosaic image of the Triangulum galaxy (M33) was released on January 7 and shows one of dozens of our celestial neighbours in our suburb of the universe known as 'the Local Group'.

But in a new 665-million pixel image taken by the NASA/European Space Agency (ESA) Hubble Space Telescope, the spiral galaxy's billions of stars are brightly showcased.

In the past, star-formation histories in the Local Group have been measured one galaxy at a time, often using different analysis techniques.

Usually when astronomers talk about our neighbouring galaxy, they're talking about Andromeda, which is a cozy 2.5 million light-years away.

The latest image was taken with Hubble's Advanced Camera for Surveys.

The runt of the litter also lacks the conventional bright bulge at its heart and does not have a bar connecting its spiral arms to the center. It is the largest high-resolution mosaic image of this galaxy ever assembled, composed of 54 Hubble fields of view spanning an area more than 19,000 light-years across.

Most notably, Triangulum's star formation is 10 times more intense than in the comparable Hubble panorama of the neighboring Andromeda. New stars form at a rate of approximately one solar mass every two years.

Which is weird, because newborn stars devour dust and gas, leaving less fuel for new celestial bodies to emerge.

These enormous stellar nurseries rank among the largest and brightest in the Local Cluster, shining with the light of ionized hydrogen.It was the presence of these active star forming regions that led astronomers to target Messier 33 with the Hubble telescope.
