A meteoroid is a small rocky or metallic body traveling in space. A meteor is the streak of light we see when a meteoroid enters Earth's atmosphere and burns up due to friction. A meteorite is a piece of the meteoroid that survives its fiery journey through the atmosphere and lands on Earth's surface.
in dense, cold clouds of gas and dust known as molecular clouds, which are found in the interstellar medium of galaxies
we currently dont know
stars, gas, dust, planets, and dark matter.
A "shooting star" is a meteor
when gravity causes a dense clump of gas and dust to collapse inward
the expation of the universe
a galaxy experiencing a rapid, intense rate of star formation, producing new stars hundreds or even thousands of times faster than typical galaxies like the Milky Way
the region between the orbits of the planets Mars and Jupiter
when a low to medium-mass star, like our Sun, runs out of nuclear fuel and sheds its outer layers
dense clumps of gas that collapsed under gravity a few hundred million years after the Big Bang
a massive system of stars, gas, dust, and dark matter held together by gravity
the Kuiper Belt and the Oort Cloud
a star's core collapses under its own gravity, triggering a massive explosion that blasts the outer layers into space
The state of the universe before the Big Bang is unknown
