Can we see the Triangulum Galaxy?
The Triangulum Galaxy is the third-largest member of the Local Group of galaxies, behind the Andromeda Galaxy and the Milky Way. It is one of the most distant permanent objects that can be viewed with the naked eye.
How was the Triangulum Galaxy formed?
The Triangulum Galaxy may be an example of an “inside-out” galaxy formation. In this process, gas is exhausted at the galaxy’s inner core and is accumulated toward the outer edges of the galaxy. This results in an inner core and outer halo with different compositions.
Is Andromeda bigger than the Milky Way?
But the Andromeda galaxy is a whole separate galaxy, even bigger than our Milky Way. In a dark sky, you can see that it’s big on the sky as well, a smudge of distant light larger than a full moon.
Will Triangulum galaxy collide with Milky Way?
Hubble Space Telescope observations indicate that the two galaxies, pulled together by their mutual gravity, will crash together in a head-on collision about 4 billion years from now.
Who discovered the Triangulum Galaxy?
William Parsons, 3rd Earl of Rosse

When did the Hubble Space Telescope discover the Triangulum Galaxy?
This image of NGC 604 is constructed from observations taken with Hubble’s Wide Field and Planetary Camera 2 in 1994, 1995 and 2001. Spiral galaxy M33 is located in the triangle-shaped constellation Triangulum, earning it the nickname the Triangulum galaxy.
How big is the Hubble image of M33?
Comprised of 54 separate Hubble fields of view, this image is the largest high-resolution mosaic of M33 assembled to date by any observatory. It resolves 25 million individual stars in a 14,000-light-year-wide region spanning the center of the galaxy.
Which is the third largest galaxy in the Milky Way?
About half the size of our Milky Way galaxy, M33 is the third-largest member of our Local Group of galaxies following the Andromeda galaxy (M31) and the Milky Way. Comprised of 54 separate Hubble fields of view, this image is the largest high-resolution mosaic of M33 assembled to date by any observatory.
Which is the nebula in the Hubble mosaic?
The full Hubble mosaic is represented by the irregularly shaped region, while the cropped version (shown above) is outlined by the rectangle. NGC 604 is an enormous star-forming nebula in one of M33’s spiral arms.
