Question 1

True or false: The Antennae Galaxies are named for the long tidal tails that look like insect antennae.

Accepted Answer

True. Their distinctive antenna-like streams of stars and gas were formed by gravitational interactions during their ongoing collision.

Question 2

True or false: The Antennae Galaxies are visible to the naked eye from a dark sky location.

Accepted Answer

False. They are too faint (magnitude ~10-11) for naked-eye viewing; binoculars or a small telescope are needed.

Question 3

True or false: Their collision has triggered a massive burst of star formation, including some of the brightest known super star clusters.

Accepted Answer

True. The merger shockwaves compress gas, creating ultra-dense clusters with thousands of young stars—among the most luminous ever observed.

Question 4

True or false: The two galaxies are moving away from each other at high speed.

Accepted Answer

False. They are actually colliding and moving toward each other, gravitationally bound in a slow dance that began hundreds of millions of years ago.

Question 5

True or false: These galaxies are located about 45 million light-years from Earth in the constellation Corvus.

Accepted Answer

True. The Antennae Galaxies (NGC 4038/4039) are indeed roughly 45 million light-years away in Corvus, making them a nearby interacting pair.

Question 6

True or false: The Antennae Galaxies will eventually merge into a single elliptical galaxy in about 4 billion years.

Accepted Answer

True. Simulations predict this pair will complete their merger into an elliptical, similar to the future fate of the Milky Way and Andromeda.

Question 7

True or false: Most of the stars in the Antennae Galaxies have already collided with each other.

Accepted Answer

False. Stars within galaxies rarely collide due to vast empty space; the interaction mostly affects gas and dust, not stars themselves.

Question 8

True or false: The Antennae Galaxies were first discovered by the Hubble Space Telescope in 1990.

Accepted Answer

False. They were discovered much earlier—William Herschel found them in 1785. Hubble later provided detailed images of their collision.
