What are the Antennae galaxies?
Q: What are the Antennae galaxies?
A: The Antennae galaxies are two colliding galaxies in the constellation Corvus.
Q: How long does the collision of the Antennae galaxies take?
A: The collision of the Antennae galaxies takes hundreds of millions of years, maybe even a billion years.
Q: What is the starburst phase of the Antennae galaxies?
A: The starburst phase of the Antennae galaxies is a phase where extremely rapid star formation occurs, and it might last a few hundred million years.
Q: When were the Antennae galaxies discovered?
A: The Antennae galaxies were discovered by William Herschel in 1785.
Q: How are the Antennae galaxies known as?
A: The Antennae galaxies are known as the Antennae galaxies because they have two long tails of stars, gas and dust ejected from the galaxies as a result of tidal force in the collision that look like an insect’s antennae.
Q: What are the Antennae galaxies joining to become in the future?
A: The nuclei of the two galaxies of Antennae galaxies are joining to become one giant galaxy, sometime in the future to form an Elliptical galaxy.
Q: How far are the Antennae galaxies from the Milky Way?
A: The interacting galaxies of Antennae galaxies are nearer and less remote to the Milky Way than previously thought—at 45 million light-years instead of 65 million light-years.
