The birth of a star is one of the most spectacular events in the universe. It begins when a cloud of gas and dust collapses under its own gravity.
2. The death of a star
The death of a star is also a dramatic event. When a star runs out of fuel, it begins to collapse under its own gravity.
3. A black hole)
A black hole is a region of space where gravity is so strong that nothing, not even light, can escape. Black holes are formed when massive stars collapse at the end of their lives.
4. A neutron star
A neutron star is a collapsed star that is made up almost entirely of neutrons. Neutron stars are incredibly dense and have very strong magnetic fields.
5. A nebula
A nebula is a cloud of gas and dust in space. Nebulae can be formed by the death of a star, the birth of a star, or the collision of two galaxies.
6. A galaxy
A galaxy is a collection of stars, gas, and dust that is bound together by gravity. There are billions of galaxies in the universe, and each galaxy contains billions or trillions of stars.
7. A meteor shower
A meteor shower occurs when the Earth passes through a cloud of debris left behind by a comet or asteroid. As the debris enters the Earth's atmosphere, it heats up and burns, creating a streak of light in the sky.
8. A solar eclipse
A solar eclipse occurs when the Moon passes in front of the Sun, blocking its light from reaching Earth. Solar eclipses can be total, partial, or annular.
9. A lunar eclipse
A lunar eclipse occurs when the Earth passes between the Sun and the Moon, casting its shadow on the Moon. Lunar eclipses can be total, partial, or penumbral.
10. A comet
A comet is a ball of ice, dust, and rock that orbits the Sun. Comets are formed in the Oort cloud, a region of space located far beyond the orbit of Neptune.
