Explanations: answer key for all 10 questions

Q1: What is the Sombrero Galaxy's Messier number?
Answer: M104
It was added to the list later.
Q2: Which constellation is it in?
Answer: Virgo
It lies near the border with Corvus.
Q3: Why does it look like a sombrero?
Answer: We see it almost edge-on with a dust lane across a bright bulge
The dust forms the hat brim.
Q4: What is the dark band across the galaxy?

Answer: About 30 million light-years
It is a fairly nearby galaxy.
Q6: What lies at its center?
Answer: A supermassive black hole
It is about a billion times the Sun's mass.
Q7: What does the galaxy have in large numbers?
Answer: Globular clusters
Estimates run into the thousands.
Q8: Who discovered the Sombrero Galaxy in 1781?
Answer: Pierre Mechain
He worked with Charles Messier.
Q9: Which telescope made a famous 2003 image of it?
Answer: Hubble Space Telescope
It became a classic picture.
Q10: What did Webb's infrared view in 2024 highlight?
Answer: A clumpy outer ring of dust
The bulge looks much fainter.

Sombrero Galaxy Quiz – The Dark Dust Lane and Glowing Bulge

The Sombrero Galaxy, also called Messier 104, lies about 30 million light-years away in the constellation Virgo. Pierre Mechain discovered it in 1781, and it was later added to Messier's catalog.

We see it almost edge-on, so a dark lane of dust cuts across its bright central bulge, making it look like a wide-brimmed hat. A supermassive black hole about a billion times the Sun's mass sits at its center.

The galaxy has thousands of globular clusters. Hubble captured a famous visible-light image in 2003, and in 2024 Webb's infrared view showed the dust ring in clumpy detail.
