M33: Rise, Set, Nighttime Path

M33

M33 Daily Motion

M33 will rise before twilight begins, at 19:07, and will reach 11° elevation by the time twilight commences at 20:15. It will reach its transit at 82° by 03:00 and gradually fade away as the night ends at 05:54, maintaining an elevation of around 54°.
M33 will be visible until March, 15, when it will move too close to the Sun. During this time, its proximity to the Sun will cause it to disappear from the night sky, making it unobservable for a while.

M33 - Triangulum Galaxy

The Triangulum Galaxy (M33) is a spiral galaxy located in the constellation Triangulum. It was discovered by Giovanni Battista Hodierna before 1654 and independently by Charles Messier in 1764. M33 is the third-largest member of the Local Group of galaxies, which includes the Milky Way and the Andromeda Galaxy.

M33 spans about 60,000 light-years across and contains approximately 40 billion stars. The galaxy is approximately 2.73 million light-years away from Earth and has an apparent magnitude of 5.7, making it visible to the naked eye under dark skies and easily seen with binoculars or a small telescope.

M33 Image Gallery

DSS Blue

M33 photo taken with blue filter
These images are valuable for highlighting the presence of younger, hotter stars, which emit more light in the blue wavelengths.

DSS Red

M33 photo taken with red filter
These images are excellent for detecting older, cooler stars, as well as emission nebulae, which glow primarily in the red due to hydrogen alpha emissions.

DSS Near-Infrared

These images can penetrate dust clouds that obscure visible light, revealing structures and objects hidden within.

DSS Composite image

M33 color image
DSS Color images are composite images created by combining the blue, red, and often near-infrared images to produce a full-color representation.

The photos are taken from the Digitized Sky Survey 2 (DSS2), which was produced at the Space Telescope Science Institute (STScI) under NASA contract, using data from the UK Science and Technology Facilities Council (STFC), the European Southern Observatory (ESO), and the National Geographic Society-Palomar Observatory Sky Survey (POSS II).

Special thanks to the National Optical Astronomy Observatory (NOAO), the Royal Observatory, Edinburgh, and the California Institute of Technology for their significant contributions.

The graph illustrates the annual visibility pattern of a M33, providing a comprehensive overview of its daily appearances and transit times throughout the year.
The graph is structured with the vertical axis showing the hours of the day, ranging from 12 AM to 12 AM the next day, while the horizontal axis spans each day of the year.
The reddish shaded area indicates the periods when the M33 is above the horizon, visible to observers. The white line marks the times when the celestial object reaches its highest point in the sky each day, known as the transit.
