What is the absolute and apparent magnitude of Sirius B?
Sirius B is a faint white dwarf companion of Sirius A
It has an apparent magnitude of +8.3 and an absolute magnitude of +11.18
What is the temperature of Sirius B?
Sirius B is a white dwarf and has a spectral type of DA2.
As it is a white dwarf, it is cooling all the time. It's current temperature is about 25,200 K
Yes. It is in the constellation of Canis Major. As we see it, it is the brightest star in the night sky. But maby we can see a brighter star
How did astronomers discover that the star Sirius was moving away from earth?
They craped in the toilet and Looked up in the sky and said sh!t Sirius is moving away from earth.
Sirius is a star, so it doesn't have an orbit like the planets do. Thus, you can't calculate a year for Sirius. All you can do is estimate its age in Earth years.
What is the composition of Sirius?
Eight channel electronic music for trumpet, soprano, bass clarinet and bass is the composition of 'Sirius' by Karlheinz Stockhausen [August 22, 1928-December 5, 2007].
It only works in one direction- moving to the future at the rate of 1 day per day. It does not work in reverse, and you cannot speed it up.
Sirius is a star, I hope this detailed information helps.
Where can a sirius antenna be purchased?
A Sirius radio antenna can be purchased at many retailers. Future Shop, Best Buy, Costco, Walmart, and Visions Electronics all carry various Sirius radio antennas.
Is Sirius A a main sequence star?
Polaris - the current North star is a multiple star system., consisting of the main star and smaller companions.
The main star Alpha Ursae Minoris is a bright star, a 6 solar mass supergiant and it is a main sequence star.
Orbiting very close to this main star is a white dwarf of roughly 1.5 solar masses. This is not a main sequence star.
Orbiting further out is the third companion, a 1.39 solar mass star. This is a main sequence star.
There are also two more distant components (α UMi C and α UMi D) - Polaris is thought to be part of an open cluster - I do not know if these later two stars are main sequence or not.
What is the final stage for Sirius b?
Sirius B is already a white dwarf. The next transformation will be to become a black dwarf, but not for many many years.
Does the star Sirius or Betelgeuse have a greater parallax angle?
Sirius will have a greater angle, because it is closer to us.
Where is the Sirius constellation?
Sirius is NOT a constellation - it's a star, the brightest star in our night sky. It's in the constellation, Canis Major the Great Dog - just left of Orion.
How much would you weigh on Sirius A?
If you weighed 100lb on Earth you would weigh about 5,400 lb for about a millisecond before you were incinerated and turned into vapour.
Sirius A is a star about twice the size of our Sun.
What elements are in the the star Sirius?
Hydrogen and helium are the most abundant elements in a star.
Will Sirius B eclipse Sirius A this New Year's Eve in 2012?
No, for several reasons.
The first and most important is that Sirius B and Sirius A have, as seen from Earth, a minimum angular separation of 3 arcseconds. They never eclipse each other.
Also, Sirius B is much smaller than Sirius A, and they're at about the same distance from Earth, It's too small to block more than a miniscule fraction of light from Sirius A. A more accurate description of what would be seen from Earth if it could actually line up with A would be a "transit", not an eclipse.
Finally, periastron occured in 1994. The two stars have actually been moving further apart since. Since the period is about 50 years, the next time they're close together won't be for another three decades, and certainly not this year.
What is the apperant magnitude of Sirius?
Sirius is actually a binary star system.
Sirius A has an apparent magnitude of -1.46 whereas Sirius B has an apparent magnitude of 8.3
Most Creationists have no problem with the speed of light. Only the "young Earth" or "young universe" branch have to deal with the issues of light sources "billions of light-years" away. Some have rather interesting ideas about how to reconcile the two ideas, ranging from "God started the universe with everything already in place, including forces that act at light-speed" to invoking space-time dialation due to the excessive mass postulated at the start of the universe.
Answer:YES. The only thing we refuse to believe is evolution. We believe that God created everything including scientific properties, planets, stars, etc. Answer:Some do and some don't. Almost all do. And not surprisingly. Creationists are, in general, those who believe God created life on earth and also created the heavens and all we see in the universe. There isn't one shred of physical evidence to hold up that says He didn't. God is not disproved by anything man has learned, has discovered, about life on earth of about the universe as a whole. Nothing anyone can hold up disproves God. Creationists believe science and (most of) the facts about creation that have been illuminated by Man's understanding. There is no conflict between science and belief for most Christians. But there are a few who do not believe. They are the followers after Young Earth Creation (YEC). Let's look at them.
Young Earth Creationists believe that earth and life on it have only been around a few thousand years. They believe the universe as a whole has only been about for a little longer than that. Can anything more absurd be considered? If galaxies exist (which they do) and they are billions of light years away (which they are), how could the light have gotten to earth in a few thousand or a few tens of thousands of years? The answer is simple: it couldn't have. These few followers of YEC represent a small minority of Christians, and their illogical attachment to the ideas YEC presents. Man's mind could, in a way, be considered to be a reflection of God's. Are we not, after all, created in His image? If so, then why would anyone dishonor (defile?) His creation by not using it? It is unconscionable to do so, to set aside this fine(st) gift from Him and, instead, assert flawed (man-made) ideology for the clear evidence presented by what science has discovered. The truth is that He has given them eyes, but they cannot see.
Answer:Creationists agree with scientists about the current speed of light, and also with the existence of stars billions of light years away as these facts are well supported. The implied questions are: 1)How can Creation Scientists reconcile the Genesis account of creation with the billions of years seemingly necessary for starlight to reach earth? 2)How then, can Young Earth Creationists believe that the universe is less than 10,000 years old? It has been a subject of some investigation. Clearly, some explanation is required for how light from stars billions of "light years" away could be seen here, if the "billions of years" did not exist.Old Earth and Genesis
According to Progressive Creationists who espouse this view Genesis Chapter 1 may be read as: "In the beginning," (before "day" 1) God created the universe--the stars, planets and other heavenly bodies over billions of years. In verse 2, perspective shifts to the earth's surface. On the first "day," the earth started out dark, covered by clouds, and then God created sunlight to penetrate the darkness. (v. 3-5). On the fourth "day," v. 16, God caused the Sun, Moon and stars to become visible on earth, having made them earlier. Also at this point God commanded these heavenly bodies to mark off time. In this view, each "day" of creation week may represent billions of years.
Another point PCs make indicate that the phrase "And it was so" e.g. verse 11 might be better understood as "and it came to pass," which may have happened over an unspecified amount of time.
However, this view cannot reconciled with Exodus 20:11: "For in six days the LORD made heaven and earth, the sea, and all that in them is,..."
Young Earth and Distance to the Stars
Some Christians who adhere to the Genesis account of creation propose that the distance to the stars may not actually be as great as scientists believe. But that is not a theory accepted by Creationists. The measurement of distances appears to be quite sound. So the conclusion must be that the universe really is very, very big.
Mature Creation
Other Christians suggest that God may have created starlight in transit, something like the creation of Adam as a mature man. Yet it seems uncharacteristic of the Christian God to create such illusion. After all, we see stars changing, sometimes even exploding. If this theory were correct, starlight would be more like a painting than a visual record. So Creationists generally reject this view, as well.
Lightspeed Variability
Of course, any theory relies on some assumptions, and Creationists are determined to carefully examine them. The usual assumption is that the speed of light is constant regardless of the inertial reference frame of the observer. By current measurements it is calculated that light in a vacuum travels about 6 trillion miles in a year. But can we assume that it has always traveled at the same rate? Such an assumption could be right or wrong. So some Creationists propose that the rate of speed of light was much faster in the past. However, the impact of a changing lightspeed on the universe is not known.
Speed of Time
Albert Einstein discovered that the rate at which time passes is not a universal constant, but is dependent on motion and gravity. For example, a clock traveling at near the speed of light relative to us would tick very slowly if we could observe the clock. Astronauts observing the clock directly would observe the clock ticking perfectly normally. This is called time dilation. A clock at sea-level, nearer to the source of gravity, ticks more slowly than a clock on a mountain top. Atomic clocks have measured the effects of time dilation.
Some Creationists say, if we assume that the universe is finite, and that our solar system is near the center (which is scientifically plausible) the earth would be in what is called a gravitational well. While the effect appears to be small today, if the universe is expanding as astronomers believe, the effect would have been greater in the past. Thus time on earth would have passed more slowly than elsewhere in the universe as measured by observers elsewhere in the universe, due to the effect of gravity. Thus the stars may be billions of years old, while the earth is young. This possibility is intriguing.
Relativity and Synchronization
Just as 12 Noon in one part of the earth happens at a different relative time in another part of the earth, time may measure differently in different parts of the universe. You can in fact travel West to another time zone on earth, and arrive at the same time, or earlier, than when you left the first time zone! This is illustrative; it is clear that time zone differences are not relativistic affects.
While today astronomers use what is called Cosmic Universal Time, long ago Cosmic Local Time was used. If the description of cosmic events in Genesis was in Cosmic Local Time, which is entirely plausible, then starlight would have been created on day 4 in its own locality and arrived on day 4 locally on earth. Since the passage of time reduces to zero at the speed of light according to Einstein, the light itself would arrive instantaneously from its own perspective, that is, if the photons themselves could experience the trip. Observers from earth would still measure the light as traveling at c. This is another intriguing, if perplexing, possibility.
Natural Law versus The Supernatural
When studying astronomy, a frequently unnoticed assumption is that of naturalism, the assumption that nature is all that there is, and that everything must occur in accordance with the laws of nature. This is certainly in direct conflict with the Bible, which consistently asserts that God is not bound by natural laws. While He usually allows things to progress according to natural law, he does not always. The times when He does not are called miracles. All of creation week would fit that definition. The apparent lack of a natural mechanism to deliver starlight cannot be used to discredit what would in any case be a supernatural creation.
To claim that distant starlight is impossible to reconcile with a young earth, and that therefore, the literal biblical timetable (as understood by young earth creationists) is impossible is really circular reasoning. That argument begins with the assumption that nature is all there is, and concludes that therefore what we can observe by natural means is all there is.
Where can one go to buy a Sirius boombox?
A Sirius boombox may be purchased The Source, Future Shop or Best Buy. Some mass retailers such as Walmart or Target may also carry a few models of the Sirius brand boombox.
Sirius is twice as far from earth as which star?
Probably one of the Alpha Centauri stars at about 4.3 light years.
No. Sirius is far from a cold star.
Sirius is actually a binary system about 8.6 light years away. Sirius A is a white main sequence star just over twice the size of the sun. Sirius B is a white dwarf stellar remnant of about 0.978 solar masses.
The temperature of the two stars are far higher than that of our sun. The sun is about 5778 Kelvin, Sirius A is almost twice that at 9,940 K and Sirius B is many times that at 25,200 K.
