🌌 What is a galaxy?

A galaxy is a huge group of stars 🌟, planets, and space dust that all stick together because of gravity. Imagine it like a big, sparkly city in space! Our home, the Earth, is in a galaxy called the Milky Way 🥛.

Galaxies come in different shapes—some look like spinning pinwheels, and others are round like balls!

A galaxy is a massive collection of stars, planets, gas, and dust held together by gravity. Think of it like a giant cosmic family! Our solar system lives in the Milky Way Galaxy, which has over 100 billion stars! 🌌

Galaxies can be spiral (like a pinwheel), elliptical (round or oval), or irregular (no clear shape). The Milky Way is a spiral galaxy with long, curved arms.

Fun fact: The closest big galaxy to us is Andromeda, and it’s racing toward us! But don’t worry—it won’t crash into us for billions of years.

A galaxy is a gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter. The Milky Way, our home galaxy, is a barred spiral galaxy about 100,000 light-years across and contains over 200 billion stars! 🌠

Galaxies are categorized by shape:

• Spiral galaxies (like the Milky Way) have rotating arms and a central bulge.
• Elliptical galaxies are smooth and oval-shaped, with little gas to form new stars.
• Irregular galaxies lack symmetry and often result from collisions.

Galaxies cluster together—the Milky Way is part of the Local Group, which includes Andromeda. In about 4.5 billion years, the Milky Way and Andromeda will merge!
