Mount Wilson‚ Hubble found that the Andromeda nebula‚ a cloudy patch in the sky‚ was so far away it could not be within our own galaxy. This illustrated that the Milky Way is just a small object within the universe. Later‚ by examining the light of distant galaxies‚ he showed that the universe is expanding‚ and that everything in it is moving away from everything else. In the early mid-1920s‚ Hubble began conducting new research with Milton Humason‚ on the galaxies’ spectral shifts and unique distances

William John Andromeda Strain-Response Ranger The part of the text that I chose to respond to was when Jaggers‚ Comroe‚ Mancheck‚ and Wilson were reviewing the footage that Lieutenant Wilson captured during his flybys. The footage captured an old man walking amongst the dead bodies. My first reaction was of shock about the horror of the grisly scene‚ but then I thought “Why does that guy seem to create the deaths?” “Isn’t the bacteria supposed to be the cause of so many deaths?”.

Looking Into Space: Questions: 1. A galaxy is a collection of planets of stars and space. The name of our galaxy is the “milky way”‚ and its shape is of a spiral. 2. Another galaxy found in space is called “Andromeda”. 3. There are millions upon millions of galaxies in the universe. 4. Cosmology is the study of the cosmos. 5. Light Year: The distance that light travels in a vacuum in one year‚ approximately 9.46 trillion (9.46 × 1012) kilometers or 5.88 trillion (5.88 × 1012) miles. Star:

What we know was that apart from our sun and planets‚ there are millions of stars everywhere and many nebula‚ which were considered as gaseous clouds. Even the best telescopes of the time couldnt reveal that many of the gaseous clouds were infect group of stars galaxies contains million of stars.

Galaxy S6 vs. Galaxy Note 4 - Diseño Diferencia clara en este sentido‚ sobre todo por el hecho de que el Note 4 tiene seis meses de vida‚ y el S6 acaba de ser anunciado. El Galaxy Note 4 sólo tiene bordes metálicos en el dispositivo‚ mientras que la cubierta trasera es de plástico y se puede quitar‚ así como la batería. El S6 se encuentra en una carcasa de metal‚ algo nuevo en el teléfono. La mejora en la línea visual y el diseño general es obvia. Es un hermoso dispositivo‚ bien construido y‚ a

Answers 1. What does Hubble’s law predict about the speed of a galaxy far away from the Milky Way compared to one that is closer? Hubble’s law predicted that galaxies were moving away from earth at a rate proportional to their distance from us. The farther away from the Milky Way a galaxy is‚ the larger the redshift is. The farther away a galaxy is‚ the faster it is moving away. Conversely‚ blueshifted galaxies‚ such as Andromeda‚ are moving closer to the Milky Way. 2. In a few sentences‚

“A Hubble Space Telescope photograph of the universe evokes far more awe for creation than light streaming through a stained glass window in a cathedral.” We know more about our universe than we ever have thanks to the Hubble Space Telescope’s clear crisp photos of objects far away in space. “Earth’s atmosphere alters and blocks the light that comes from space. Hubble orbits above Earth’s atmosphere‚ which gives it a better view of the universe than telescopes have at ground level.” (NASA‚ 2009)
