Basic Information
- Name: Phantom Galaxy (Messier 74, M74, NGC 628)
- Type: Grand Design Spiral Galaxy
- Location: Constellation Pisces
- Distance from Earth: Approximately 32 million light-years.
- Apparent Magnitude: 9.4, making it a relatively faint object for amateur astronomers.
- Size: Spans about 95,000 light-years, slightly smaller than the Milky Way.
Physical Characteristics
- The Phantom Galaxy is a grand design spiral galaxy, meaning it has well-defined and prominent spiral arms.
- It is viewed nearly face-on from Earth, providing a stunning view of its symmetrical structure.
- The galaxy is rich in young, hot stars, which illuminate its spiral arms, and contains regions of active star formation.
- Its core is relatively dim compared to other galaxies, which makes it challenging to observe with small telescopes.
Discovery and History
- The Phantom Galaxy was discovered by Pierre Méchain in 1780 and later included in Charles Messier's catalog of deep-sky objects.
- It has been extensively studied due to its nearly perfect spiral structure, making it a textbook example of a spiral galaxy.
Observational Highlights
- Visibility: The Phantom Galaxy is best observed in the autumn months in the Northern Hemisphere when the constellation Pisces is high in the sky.
- Best Observing Tools: A medium to large telescope is recommended to observe its faint details. Long-exposure astrophotography can reveal its intricate spiral arms.
- Challenges: Due to its low surface brightness, it is considered a difficult target for amateur astronomers without dark skies.
Interesting Facts
- Star Formation: The galaxy contains numerous H II regions, which are areas of ionized hydrogen gas where new stars are actively forming.
- Supernovae: M74 has hosted several observed supernovae, making it an important galaxy for studying stellar evolution and death.
- Multi-Wavelength Observations: Recent images from the James Webb Space Telescope and Hubble Space Telescope have revealed incredible details of the galaxy, including its star-forming regions and dust lanes.
How to Locate the Phantom Galaxy
- Find Pisces: Locate the faint constellation Pisces in the night sky. The Phantom Galaxy is situated near the star Eta Piscium.
- Use a Star Map: A detailed star map or astronomy app can help pinpoint its exact location.
- Enhance Visibility: Observing from a dark-sky location and using a telescope with a wide field of view will improve your chances of spotting this faint galaxy.
Personal Note
This remarkable, albeit slightly hazy capture took a fabulous 33 minutes exposure. Considering the amount of light pollution faced on the day, the image is at least distinguishable. Standing at a massive distance of 35 million light years, the capture is my personal second most distant one. When the galaxy was discovered initially in 2013, there was a supernova visible right next to it, which was visible for 180 days. Unfortunately it is no longer there, but that does not mean we cannot leave it to the imagination.
