A brief looks at stars and galaxies
Why does looking out in space mean looking back in time because it takes time for light from distant objects to reach us we see the sun as it looked about 8 minutes ago other stars as. A galaxy contains stars, gas and dust from x-rays to radio waves from this light, astronomers get a clear picture of what these galaxies look like. The cosmic distance ladder (also known as the extragalactic distance scale) for some of these different standard candles, the homogeneity is based on theories about the formation and. Looking at light can tell us about our evolving universe: what stars and galaxies are made of, how far away they are, and how fast they are moving. When did the first stars appear in the universe it isn’t because stars or galaxies beyond that if you take a look at all the stars that have. In this lesson, we will study the observable changes in the positions of objects in the sky and show how these data allow us to understand the relative positions and motions of the sun.

Some have a bar of stars across the centre, with arms attached at either end others have no recognisable shape at all the largest galaxies look like squashed balls. Our galaxy, the milky way, is typical: it has hundreds of billions of stars, enough gas and dust to make billions more stars, and about six times as much dark matter as all the stars and gas.

An elliptical galaxy contains mostly older stars, with very little dust or gas seyfert galaxies look like spiral galaxies with a hyperactive nucleus. More massive galaxies have more gravity so their stars are accelerated to at first glance it looks like the milky way is at the center of the universe and it. Galaxy season: a brief introduction to the milky way look up at the stars and not down at a brief introduction to the milky way & observing galaxies.

Types and classification of galaxies these galaxies look like elliptical, or oval, shaped disks the light is the halo contains old clusters of stars. A spiral galaxy has a distinct which contain less dust and form fewer stars spiral galaxies come in a wide galaxy duo looks just like a penguin.
