Continuing astronomical studies can help advance our society one day (ex.: finding new energy sources via studying stars). We can also protect the planet from potential catastrophic events. Many federal and privately founded organizations understand the importance of funding this science field.]]> 2022-01-06 17:02:42 UTC https://padlet.com/phamt665/i1227i73nuwpg40k/wish/1979131533 phamt665 https://padlet.com/phamt665/i1227i73nuwpg40k/wish/1988635610 Cosmology is the study of origins, properties processes, and evolution within our universe. From our studies thus far, astronomers estimate the Big Bang created the universe up to 13.7 billion years ago.]]> 2022-01-12 16:35:28 UTC https://padlet.com/phamt665/i1227i73nuwpg40k/wish/1988635610 phamt665 https://padlet.com/phamt665/i1227i73nuwpg40k/wish/1988640561 Order is everywhere around us -- including within the universe. The order we see in astronomy goes as follows: planet, solar system, galaxy, universe. There are many other miscellaneous components without galaxies such as stars (ex.: the sun), dwarf planets, asteroids, and comets.]]> 2022-01-12 16:37:27 UTC https://padlet.com/phamt665/i1227i73nuwpg40k/wish/1988640561 phamt665 https://padlet.com/phamt665/i1227i73nuwpg40k/wish/1988650465 Astronomical units, or "AU", are units of distance within the universe. An AU is equivalent to the distance between the Earth and sun which is roughly 1.5 x 10^8 km. Light-Years are also a common unit of measurement in astronomy. The speed light travels in one year is around 9.46 x 10^12 km.]]> 2022-01-12 16:41:34 UTC https://padlet.com/phamt665/i1227i73nuwpg40k/wish/1988650465 phamt665 https://padlet.com/phamt665/i1227i73nuwpg40k/wish/1988663643 Like all other planets in the Milky Way, Earth rotates are the sun in an orbiting pattern. Its rotation helps us decipher the time. One (1) full rotation is equivalent to the length of one day for us. This is the reason we see the sun in the morning and why it sets in the evening. The Earth's rotation was discovered years ago by a scientist named Jean-Bernard-Leon Foucault. He created a pendulum that simulated the orbit of planets around the sun by attaching a bob weight to a wire and enacting minimal force on it.]]> 2022-01-12 16:47:02 UTC https://padlet.com/phamt665/i1227i73nuwpg40k/wish/1988663643
