NASA's Cosmicopia - - Ask Us - - Stars. Can you give me some good Web resources about stars? You might want to check through our sister site, Imagine. Universe! And there's a star finder at the University of. Turku in Finland. Dr. Louis Barbier and Beth. Pocket Sand is when sand or other granular objects are kept in the pockets for use in self-defense. If a person using pocket sand is in a confrontation, they can draw. Dust storms don't just happen in the middle of the desert. They happen in any dry area where loose dirt can easily be picked up. Grains of sand tossed into. Large 12-1/2 x 16-1/2 hood opening makes this ideal for collecting dust from miter saws, lathes, radial arm saws, carving, sanding, and. This question comes from Sheldon Grimshaw. Barbier. I heard about a Hubble experiment where it stared into the darkest region of space and the counted the points of light it could see. It also reminds me of the famous German children's song . If we talk about the . Yes, there is a basic restriction as to what we can observe, no matter how much we try. From the latest cosmic background images, we know that the Universe is 1. Therefore, we will never see any stars or galaxies more distant from us than 1. This, of course, does not mean we are in the center of the Universe, just in the center of the portion that we can observe. From Dust puts the player in control of a god that must lead the natives of the world away from the dangers that lie within and onto the promise of the.

Sprinkling of neural dust opens door to electroceuticals Wireless, implantable sensors the size of a grain of sand could have wide use in body monitoring.

Now we have to make couple of basic assumptions: Galaxies are evenly distributed throughout the Universe (locally clumped in galaxy clusters though). The Hubble deep sky image (which you mentioned), taken in a region with no known foreground stars, has indeed shown to us that there are as many galaxies at the largest distances as there are close to us. Typical galaxies have about the same numbers of stars, on average. Actual numbers in individual galaxies can vary widely. Even, if galaxies looked different in the past (another result from the Hubble image), they formed into a similar set of galaxies, with a similar number of stars as the ones we see close to us. Now, working with those assumptions: Let's assume the large Virgo cluster of galaxies is typical. It contains about 2. Let's say a typical cluster has 1. Now Virgo is about 1. Hubble result). Let's assume that galaxy clusters are typically at a distance from the nearest neighbors of 1. There are some larger galaxies, but also many smaller ones. Let's assume this is a typical size. Multiplying 1. This is the number of sand grains that you need to pile up. A typical sand grain has a size, let's say, of 0. Again let's assume these are little cubes (for the sake of simplicity). The collection of as many sand grains as there are stars in the sky would sum up to a sphere with a radius of about 3 km, i. Even if our estimate for the number of stars were off by a factor of 1. Dr. Eberhard Moebius(January 2. Do stars give off light? Anything that is hot will glow. Eric Christian(September 2. Why can't we see the stars during the daytime? You can see one star during the day - - the Sun! Eric Christian(August 2. Does the distance between the stars and Earth affect the. Just as the Earth's atmosphere makes the sun redder - -. Eric Christian(May 2. Is it true that in space a person is not able to see stars all around them like we do here on Earth? No, I hear that in space the stars look wonderful, bright (although not twinkling) and very clear. It is extremely hard to get the exposure correct to show the stars. Eric Christian(July 2. Does it become harder to see stars as you approach the equator? No, it doesn't. Your ability to see stars is mostly determined by the amount of light pollution nearby, generally from man- made lights. Dr. Louis Barbier(November 2. What can its spectrum can tell you about a star? The best write- up of this I know of is in the Imagine the Universe! Eric Christian. How so the stars burn if there is no oxygen in space? A star's energy comes from the combining of light. The process is. called nucleosynthesis. The hydrogen in a shell continues to burn into helium, but the outer layers of the star have to expand in order to conserve energy. This makes the star appear brighter and cooler, and it becomes a red giant. During the red giant phase, a star often loses a lot of its outer layers which are blown away by the radiation coming from below. Eventually, in the more massive stars of the group, the carbon may burn to even heavier elements, but our Sun will never really get past carbon. Then no new stars could be created. Stars are not 1. 00% efficient when burning hydrogen, so it is thought that there will still be some hydrogen around, but it won't be in the right form (dense gaseous clouds) for star formation. Eric Christian(August 2. How are stars' ages determined? Based on estimates of a star's mass and composition, theories can explain how stars evolve. Observations of many stars of the same class can be used to confirm these theories. Any particular star can be observed and its age determined based on these theories of stellar evolution. Dr. Louis Barbier. What are the different phases of a star? Is our Sun going through these phases? Roughly, the phases of stars are: gas cloud - > collapse to protostar - > hydrogen fusion (the star is now called a . For more information, check out the . Eric Christian. Can you tell me what color a star would be in relation to temperature? What are main sequence stars? The answers to both your questions are found in a. Hertzsprung- Russell. H- R) diagram. This diagram shows the relationship of a star's. In general. brighter stars are hotter; cooler stars are dimmer. The vast majority. These are either bright, low temperature. For more information check out any. Dr. Louis Barbier and. Beth Barbier. What is a Cepheid star? If you have any more. Imagine. the Universe! There are only a few stars that do this, but it's the same ones every night (I know Arcturus is one for sure). All of the stars are close to the horizon and very bright. Why does this happen? The effect you're seeing is almost certainly due to refraction in the atmosphere. Eric Christian. A distant star might appear blue, due to its temperature. Eric Christian(March 2. I heard on television about a star in the Milky Way galaxy that is rapidly exiting our galaxy. How could something (like a star) be so dense that it would implode? The important things to know about what makes a star implode are: Stars have a LOT of mass. Stars have a pretty low density, especially when they are in their red giant phase (which is where they are at when they implode). You can get more information on black holes and the like at the Imagine the Universe! Eric Christian. Since star clusters show no dominating disc structure, are star clusters really orbital furballs? How long is a star cluster stable before the whole thing grinds itself into space rubble? This must be the ultimate many- bodied problem with non linear collisions thrown in for good measure. Star clusters are self- gravitating groups of stars. Eric Christian. My neighbor says that the stars do not rotate. Eric Christian. I have an assignment to get the name of a star and its distance in light years from Earth. There are a number of Star Catalogs on the world wide web, but most of them are meant for scientists and are in much more detail than you need. Eric Christian Why does the parallax method of measuring star distances require observations of a star made 6 months apart? The parallax method of measuring star distances doesn't . Eric Christian. How can we see stars when they are light years away, sometimes thousands and millions of light years away? It does seem a bit unbelievable, but the important thing to remember is that stars give off a LOT of light. Eric Christian(March 2. Is there a star in our galaxy named ? Is there a web site that lists all of the stars and what constellations they are in? I can find no star named . Eric Christian. I have heard for a fee that you can . Who can I contact to do this? There are a few commercial companies that pretend to. For more information on. IAU's . Eric Christian and.
