Go to YouTube and search......face of a dog in a star....I took this video and was told that it was sirius, or the dog star. I can't argue with that because it looks like a dog.
I searched everywhere to find what a pic of the dog face in dog star looks like and came up with nothing. Maybe I am the first one to actually photograph it.

What is the brigthest star called?
The brightest star in our night sky is the star Sirius. It has an apparent magnitude of -1.46 or so. The meaning of that number is not easy to explain but to put it in context, the sun is a -26 or so (much brighter of course), and Venus can be up to -4.6. So negative numbers are brighter in this case. The star Vega is 0. The dimmest star you can see under perfect conditions is around +6.
What method do astronomers use to determine the distance to a relatively close star like Sirius?
For nearby stars, the parallax method is used.
What is the brightest star seen from Tobago?
The brightest star in the sky is Sirius. The brightest object that looks like a star is the planet Venus - which is brighter than any star. You can see it these days (Aug. 2010) after sunset in the west, as a very bright star.
What does the Star of David look like?
Star of DavidIt is a star consisting of two overlapping equilateral triangles, one pointing up and one down. An image of it can be seen at the Related Link below.

Multiple questions. See related questions.
Is Sirius A an Earth-like star?
No. There is no such thing as an "earth-like star" as Earth is a planet, not a star. Sirius A is a star that is larger and brighter than the sun.
How long is a year on Sirius?
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 sirius star?
Look up the Wikipedia article, "Sirius", for more details. Briefly, it is: the brightest star in the sky (however, some planets, which also look like stars, are brighter); 8.6 light-years away; a double star; one of the components (Sirius B) was the first white dwarf to be discovered.

Is Sirius a galaxy?
No, it's just a pattern of stars that someone once thought looked like a scorpion. If you were to move away from earth, all the constallations would look quite different.

What is the age of the star Sirius b?
It's very difficult to age individual stars, but it is estimated that the Sirius system is about 200 - 300 million years old. Sirius B became a white dwarf about 120 million years ago. Big stars like Sirius rarely last more than half a quarter billion years.
In what direction you saw SIRIUS?
I live near the equator, and see Sirius towards the east (January 2014, after sunset). If you live in the northern hemisphere, you will see it more towards the south-east; if you live far south from the equator, you will see it more towards the north-east. Note that Sirius is currently the second-brightest "star" to the east after sunset; Jupiter may also be visible (depending on your location); it will appear as the brightest "star". Jupiter is technically a planet, but it looks like a bright star.
Apart from the sun what is the biggest star seen from earth?
What do you mean by "biggest"? That it looks brightest? That its real brightness is the greatest? That it has the largest diameter? The greatest mass? The star that looks brightest for us is Sirius. Planets, however, also look like stars, and some of them look brighter than Sirius, including Venus, Jupiter, and sometimes Mars.
Why are short wavelengths of EM radiation less common then medium wavelengths?
Shorter wavelengths, like gamma rays and X-rays, require more energy to produce than longer wavelengths like visual light.
What is star Sirius made of?
Like other stars, Sirius formed when a cloud of gas and dust called a nebula collapsed under the force of gravity. As the cloud collapsed it formed two masses that heated up until the nuclear fusion of hydrogen ignited, turning the two masses into stars by 200 to 300 million years ago. The result was a binary star system consisting of the smaller Sirius A and the larger Sirius B. Since Sirius B was more massive it burned through its hydrogen fuel more quickly and eventually exhausted its fuel supply. By about 120 million years ago it has shed most of its mass while the remainder collapsed into a small, dense remnant called a white dwarf, leaving Sirius A as the larger, more massive body. Sirius A has not yet finished its fuel supply and will likely last for about another 1.5 billion years or so.
