What is the M87 Black Hole?

MESSIER 87 (M87), also known as Virgo A or NGC 4486, is a super oval galaxy in the virgin constellation. It is one of the largest and largest galaxies in the local universe, which contains trillions of stars and dense spherical clusters. M87 is particularly noteworthy that its strong relativity is sprayed, an active galaxy nucleus, and a super -quality black hole in the center. This is the first black hole in the history of the horizon telescope.

feature	detail
type	Giant ellipse galaxy
Place	Virgin constellation
Distance from Earth	~ 55 million light years
Special feature	Including a super -quality black hole, launching strong radio and X -ray signals, with glowing gaseous shots

What are some of the significant astronomical phenomena of M87?

1. Powerful radio and X -ray emissions

• The M87 is an important source of radio waves and X -rays, indicating that there is extremely thermal gas.
• The nuclear and spraying of the Galaxy can generate synchronous radiation, which moves near the speed of light near the magnetic field.

2. Super black hole

• In 2017, the event Horizo ​​N telescope (EHT) captured the first direct image of the black hole in the M87.
• The image reveals an asymmetric radio transmission ring, surrounded by the shadow of black holes.
• Black hole:
• The quality is 6.5 billion times the sun.
• It spans 38 billion kilometers (24 billion miles).
• It has such a powerful gravity and attraction, so that even no light cannot escape.

3. Bright gaseous jet

• The glowing gaseous shot extends from the M87 core to the outside.
• The shot is generated by accelerating the speed of near -light due to the gravity of the black hole.
• Due to the effect of Doppler, because the materials moving towards the earth have visually enhanced the materials, the shot is brighter on one side.

What are the characteristics of Messier 87 (M87)?

The characteristics of Messier 87 (M87) are:

• Type: Super Oval Galaxy (E0-1 PEC, NLRG SY)
• Single cluster: contains about 15,000 ball clusters (150-200 compared to the galaxy)
• Relator jet: A vibrant plasma jets extend from its core at least 4,900 light years
• Active Galaxy Nuclear (AGN): driven by super -quality black holes
• Radio Source: One of the brightest radio resources in the sky
• Interstellar medium: contains scattered gas, the elements of evolutionary stars are rich

Year	astronomer	observe
1781	Charles Messier	The M87 was discovered and it was classified as Nebula.
1880	John Derell	Use it as NGC 4486 in the new general directory.
1918	Herber Curtis	Observed “direct rays”, and was later identified as relatively theory.
1922	Edwinhab	Categorize it as an oval galaxy.
1931	Edwinhab	Determine it as part of the cluster of Virgo.
1947	Radio astronomer	Determine Virgo A as a powerful wireless power supply.
1967	U.S. Navy Research Lab	The Virgo X-1 was discovered, which was the first X-ray source in Virgo.
2019	Incident Horizure Telescope	Captured the first black hole in history.

Black Hole and Event Horizer Telescope

• M87 is where the center has a super -quality black hole.
• Estimated quality: 6.5 billion solar energy.
• The first direct image of Black Hole was captured in April 2019.

What is the timetable for the incident horizon telescope (EHT) observation?

• 2017: EHT widely observed M87.
• 2019: image release of the Black Hole event vision.
• 2021: It reveals the first polarized image and helps the research on the magnetic field around the black hole.

What is the importance and scientific importance of MESSIER 87 (M87)?

Research and scientific importance of Messier 87 (M87) Author:

• X -ray research: X -ray observations performed by Heo 1 and Einstein Observatory determine the complex sources of the core of the galaxy.
• Super large black hole research:
• Early research in 1978 estimates that its quality is 5 billion solar energy.
• The observation results of the Hubble Space Telescope will increase the estimation value to 6.5 billion solar blocks.
• Relators:
• Extend from the core to at least 4,900 light years.
• Move at a speed of near light.

You can see M87 more clearly from there?

The best visibility and observation can be completed in the following ways:

• It’s best to watch in spring.
• Location: located between the Star Ichinis and Beta Leonis.
• Obvious size: 7.2 × 6.8 arc.
• Surface brightness: 12.9 amp.
• Best equipment: Small telescope (6 cm or larger) can detect the galaxy, and a large telescope is required to observe the theory of relativity.
