Hubble Telescope captures most detailed image ever of nearby galaxy

Hubble Telescope captures most detailed image ever of nearby galaxy”

The Hubble Space Telescope has snapped an fantastic image of the Triangulum Galaxy, which is 3 million light years from our own Milky Way Galaxy.

The most detailed image yet of a 40-billion star neighbouring galaxy has been captured by the Hubble Space Telescope. It can be seen with the naked eye under the right conditions-it appears as a "faint, blurry object in the constellation of Triangulum", a statement from Hubble said.

Further research may determine if Triangulum is actually a newer member of the Local Group of galaxies. Its diameter is only 60 thousand light years in comparison with 200 thousand the galaxy Andromeda or 100 thousand the milky Way. To stitch together this big mosaic, Hubble's Advanced Camera for Surveys needed to create 54 separate images. The end result shows the central part of Triangulum and its inner spiral arms, including an estimated 10 to 15 million stars.

In the past, star-formation histories in the Local Group have been measured one galaxy at a time, often using different analysis techniques. The Triangulum Galaxy has at least an order of magnitude less stars than the Milky Way and two orders of magnitude less than Andromeda. Astronomer Steven Bellavia, an engineer at Brookhaven National Laboratory, coincidentally sent me an image he took of the galaxy with a 71mm refracting telescope and 20 megapixel astronomy camera over the course of two hours.

Astronomers think that Triangulum has avoided disruptive interactions with other galaxies, instead spending the eons tending its well-ordered spiral and turning out new generations of stars.

The galaxy contains a huge amount of gas and dust, giving rise to rapid star formation.

The NASA/ESA Hubble Space Telescope captured an incredibly detailed image of the Triangulum Galaxy. The new image from Hubble shows two of the four brightest regions of Triangulum.

The near-perfect distribution of stars within Triangulum has led researchers to believe that the galaxy has somehow avoided any major intergalactic collisions and has remained relatively untouched for aeons. The latter is the second most luminous region of ionized hydrogen within the Local Group and it is also among the largest known star formation regions in the Local Group.
