Triangulum Galaxy (M33)
Triangulum Galaxy is a face-on, spiral galaxy belonging to our Local Group of galaxies, largest of which are the Milky Way and Andromeda. As such, it is one of the nearest galaxies to our own, at 2.73 million light years

Galaxies come in wide variety and can contain from tens of millions to up to a hundred trillion or more stars. Galaxies also include other stellar objects such as brown dwarves, neutron stars and black holes, interstellar molecular clouds and dust, nebulae and, often, a supermassive black-hole in the galactic center. Galaxies come in variety of shapes including spiral, elliptical, and irregular, further classified into subtypes.
According to recent earlier estimates, there are around two hundred billion galaxies in the observable universe. This estimates was made by analysing the Hubble’s Deep Field and Ultra-Deep Field images, i.e, counting galaxies on those images for a small field of view and then extrapolating. However, new research suggests this number might actually be 2 trillion (10 times more).

Andromeda is the closest galaxy to us, estimated to be some 2.57 million light years away, and moving towards us. Our two galaxies will collide and interact in about 4.5 billion years from now, forming one bigger galaxy. Andromeda (M31)
The Whirlpool Galaxy, a spiral galaxy in the constellation of Canes Venatici, is some 23 million light years away from us and some 76,000 light years across. It’s not visible by a naked eye but can be easily observed by
These majestic pair of galaxies in the constellation Ursa Major are gravitationally locked and influence each-others shape. M81 is spiral galaxy (NGC 3031 – Bode’s Galaxy), and M82 is more irregularly shaped (NGC 3034 – Cigar Galaxy), although it is
