Or select it on the map:
This Earth map fragment is intended to illustrate celestial motion across the sky, emphasizing both bearing and elevational perspectives. The map's center point corresponds to the transit, showcasing celestial objects at their highest point, while elevation gradually decreases towards the map edges. This dynamic representation offers insights into the changing positions of celestial bodies with a focus on their bearing and elevational trajectories.

M1 - Crab Nebula

The Crab Nebula (M1) is a supernova remnant located in the constellation Taurus. It was first observed by John Bevis in 1731 and later included in Charles Messier's catalog in 1758 as the first entry. The nebula is the result of a supernova explosion recorded by Chinese astronomers in 1054 AD.

Spanning about 11 light-years across, the Crab Nebula is expanding at a rate of approximately 1,500 kilometers per second. At its heart lies the Crab Pulsar, a rapidly rotating neutron star that emits pulses of radiation from gamma rays to radio waves. The pulsar has a rotational period of 33 milliseconds, making it one of the fastest known pulsars.

The nebula's distinctive filamentary structure and colorful appearance are due to the presence of various elements, such as hydrogen, helium, oxygen, carbon, and sulfur. These filaments are remnants of the progenitor star's outer layers that were expelled during the supernova explosion.

Due to its relatively high brightness and well-defined structure, the Crab Nebula is a popular target for both amateur and professional astronomers. Located about 6,500 light-years from Earth, it has an apparent magnitude of 8.4, making it visible through small telescopes.

M1 Image Gallery

DSS Blue

M1 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

M1 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

M1 photo taken with Near-Infrared filter
These images can penetrate dust clouds that obscure visible light, revealing structures and objects hidden within.

DSS Composite image

M1 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.

Here you can see the current position of the M1 on the map, as well as its positions for rise and set. This tool allows you to track the M1's movement throughout the night, providing you with accurate and up-to-date information.

Annual motion of M1


M1 will be visible until April, 28, 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.

The graph illustrates the annual visibility pattern of a M1, 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 M1 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.
You can also view detailed visibility information in a dedicated table, including exact rise, transit, and set times for each date.
