  1. ASTRONOMY WHAT IS OUR COSMIC ADDRESS? Sour ce URL: www. ast r onomyt el escopes. net /bl og Astronomy what is our cosmic address? Have you ever wondered how enormous the universe is? Or where do we fit into it? Our cosmic address is a way of measuring our place in the universe. By understanding our cosmic address, we can better understand our place in the cosmos and the vastness of space. We all live on a planet that orbits an average star on the outskirts of a vast galaxy that contains up to 400 billion other suns. But what does that have to do with our COSMIC ADDRESS? Well, it is a way of putting into perspective just how small we are in the grand scheme of things.

  2. Let's see what each part of this address means: EARTH You know about this one. It is our planet, which is about 4.5 billion years old. THE SOLAR SYSTEM The sun is at the center of the solar system, and everything orbits around it. These include planets, moons, asteroids, comets, and meteoroids. OORT CLOUD

  3. The Oort Cloud is a vast comet field that surrounds our solar system. This can be considered to be the source of long-period comets which are thought to be leftover from the solar system's formation and are supposed to be billions of years old. LOCAL FLUFF It is a section of space with a slightly higher concentration of hydrogen gas, which is the most common molecule in the cosmos. LOCAL BUBBLE The local bubble is a relative cavity in the interstellar medium (ISM), in which the sun and nearby stars travel. ORION ARM The Solar System is located in the Orion Arm, a minor spiral arm of the MILKY WAY GALAXY that is 3,500 light-years across and about 10,000 light-years long, including Earth. MILKY WAY GALAXY The Milky Way Galaxy is a galaxy that contains the sun and all of the planets surrounding it. Every star we see in the night sky belongs to our own Milky Way Galaxy.

  4. MILKY WAY GALAXY The Milky Way Galaxy is a galaxy that contains the sun and all of the planets surrounding it. Every star we see in the night sky belongs to our own Milky Way Galaxy. LOCAL GROUP The Milky Way is a member of the Local Group, which includes all of the other galaxies in our universe. We don't know the exact number of galaxies in this Local Group. However, it is considered that most members are dwarf galaxies. VIRGO SUPERCLUSTER The Virgo Supercluster is home to approximately 100 tiny galaxy clusters, including our Local Group. LANIAKEA SUPERCLUSTER The Laniakea Supercluster is the galaxy supercluster that contains the Milky Way and around 100,000 other nearby galaxies. The observable universe, which is believed to have two trillion galaxies, is beyond Laniakea. Mind-blowing, isn't it? THANK YOU! www.astronomytelescopes.net
