3 What are 5 interesting facts about galaxy? Galaxies come in all shapes and sizes Galaxies are huge! Galaxies come in all shapes and sizes. Galaxies contain billions of stars. Galaxies are held together by gravity
Hi 4 What make a Galaxy? A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems.
5 What is the space of galaxy? The space between galaxies is filled with a tenuous gas (the intergalactic medium) with an average density of less than one atom per cubic meter. Most galaxies are gravitationally organized into groups, clusters and superclusters.
6 The Milky Way is about 1,000,000,000,000,000,000 km (about 100,000 light years or about 30 kpc) across How big is our Galaxy?
7 What is a galaxy vs universe? A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems, all held together by gravity. The Universe is all of space, matter, energy, time, and its contents, including planets, stars, galaxies, and all other forms of matter and energy.
8 Why is galaxy so big? Dense regions pulled in more and more matter through gravity, and the more massive they became, the more matter they could pull in through gravity,
9 What are the 4 types of galaxies? The smallest of galaxies contain a “mere” few hundred million stars while the largest galaxies contain up to one hundred trillion stars! Scientists have been able to segment galaxies into 4 main types: spiral, elliptical, peculiar, and irregular.
10 What is the oldest galaxy? GLASS-z13 galaxy SETTING NEW RECORDS, the James Webb Space Telescope has discovered the oldest known galaxy known to the universe and humankind. Caught and snapped in the cosmos, the GLASS-z13 galaxy was formed just 300 million years after the Big Bang, which struck 13.8 billion years ago.
