Virgo Cluster Trivia Questions

True—it's the nearest large galaxy cluster to Earth, with over 1,300 members, and M87 is its central giant.

False—it's actually about 54 million light-years away; 10 million would place it much closer, near our Local Group.

False—it contains a mix of spirals, ellipticals (like M87), and irregular galaxies; ellipticals dominate near the center.

False—Messier cataloged individual objects like M87, but the cluster as a structure was recognized later by William Herschel and others.

False—the intracluster medium is hot and X-ray bright, but its mass is comparable to stars, not greater; dark matter dominates.

True—its immense mass creates weak gravitational lensing, distorting light from background galaxies, observable in deep surveys.

True—the cluster's high velocity dispersion means some galaxies have enough speed to eventually break free into intergalactic space.

True—it's the dominant core of the Laniakea Supercluster (formerly Virgo Supercluster), and our Local Group orbits its outskirts.
