Key Facts
Meet the Twinkling Star!
Imagine a star way, way out in space, so far away it takes light years to reach us! That's V1291 Aquilae. It's like a tiny diamond in the sky, but it's actually a giant ball of super hot gas.
This star has a special name, V1291 Aquilae, and it lives in a constellation called Aquila, which means 'eagle' in Latin. It's a yellow-white color, and sometimes you can see it with your own eyes if the sky is really dark!
A Star That Likes to Change Its Clothes!
This star is super interesting because it doesn't stay the same brightness all the time. It's a 'variable star,' which means its twinkle goes up and down! Scientists noticed this in 1962 and gave it the special name V1291 Aquilae.
It's like the star is putting on a light show for us, changing its glow over a period of about 224 days. That's almost a whole year! It's one of the first stars like this that we found with such a long changing time.
What's Inside This Star?
V1291 Aquilae is a special kind of star called a 'chemically peculiar' star. This means it has unusual amounts of certain elements, like strontium, chromium, and europium, on its surface. It's also a magnetic star, with a magnetic field that's super strong, about 3,600 times stronger than Earth's magnetic field!
Imagine a magnet so powerful it could lift a whole playground! This strong magnetic field is part of what makes its brightness change.
How Far Away Is This Star?
This star is really, really far away from our Earth. It's about 278 light years away. A light year is how far light travels in one whole year, and light is the fastest thing there is!
So, it takes light from V1291 Aquilae 278 years to get to our eyes. That means the light we see from it right now actually left the star when your great-great-great-great-great-great-great-great-great-great-great-great-great-great-great-great-great-great-great-great-great-great-great-great-grandparents were alive! It's also moving towards us, but very, very slowly.
