What does an image of Sirius the Dog Star look like in UV wavelengths?

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.

In UV wavelengths, an image of Sirius the Dog Star may appear brighter and more defined compared to visible light images. UV imaging can reveal details about the star's surface temperature, composition, and activity that are not as easily discernible in other wavelengths.

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 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 method do astronomers use to determine the distance to a relatively close star like Sirius?
Astronomers use the method of parallax to determine the distance to relatively close stars like Sirius. By measuring the apparent shift in position of the star as the Earth moves around the Sun, astronomers can calculate the star's distance based on trigonometry.
If you live in Phoenix Arizona and you are facing south and you look straight up the brightest star you see what is it?
The brightest star you would see looking straight up in Phoenix, Arizona while facing south is likely Sirius, also known as the Dog Star. Sirius is one of the brightest stars visible in the night sky and is part of the constellation Canis Major.
What a spectrograph looks like?
A spectrograph typically consists of a long, narrow slit to allow light in, a diffraction grating or prism to disperse the light into its component wavelengths, and a detector to capture and record the resulting spectrum. The final output is a graph or image showing the intensity of light at different wavelengths.
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.

How do find the temperature of a star?
The temperature of a star can be determined using its color or spectrum. Astronomers use instruments like spectrographs to analyze the light emitted by a star and identify the specific wavelengths present. By comparing the intensity of different wavelengths, they can calculate the temperature of the star based on its spectrum.

What color is Sirius?
Sirius is actually a binary star system.Sirius A is a type A1V star so has a colour of Blue White -> BlueSirius B is a white dwarf.See related link for more information.Mag see More KayoDi Totoo Yung Cnagot ko
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.
