## Oldest Known Star In The Universe Discovered

### Commented Feb 11, 2014 at 15:30:23 in Science

“Nice ... Great info... I also read somewhere that we estimate the age of a star by calculation its mass and composition (found via spectral patterns which reveal elements) along with its luminosity and temperature.”

#### TanzaniaTeacher on Feb 11, 2014 at 15:56:13

“That's correct.”

“Thanks Kai M.”

“And we use the distance to measure the year ...Without the measure of time (light years) we will not be able to tell how old was the star or can we?
If we can - Can you please tell me how do we know the age of that star? ... Im very curious and this is just fascinating and mind bending for me ...LOL”

#### Richard Thompson Sr on Feb 14, 2014 at 14:43:17

“A light year is NOT a measure of time, it is a measure of distance.
A light-year (symbol: ly), sometimes written light year or lightyear is an astronomical unit of length (not time) equal to just under 9.5 trillion kilometres (or about 6 trillion miles).[note 1] As defined by the International Astronomical Union (IAU), a light-year is the distance that light travels in vacuum in one Julian year.[1]”

#### TanzaniaTeacher on Feb 11, 2014 at 14:45:39

“We don't use the distance to measure the year. We use the constant called the speed of light.

Here's a short article about the finding.

“You missed the question. I already know what you just explained. What i want to know is from which point of space the instrument was able to observe that star and what the distance between the instrument and that star?”

#### GreenMurf on Feb 11, 2014 at 14:32:45

“...distance between the star and the instrument is 6,000 light years. The star was detected by the ANU SkyMapper telescope at the Siding Spring Observatory.”

“i know that ... That wasn't my question. From which point of space the instrument was able to observed the oldest star. Was the star observed from earth?”

#### TanzaniaTeacher on Feb 11, 2014 at 15:20:36

“Yes, Australia and Chile, as is stated in the article.”

“Im so lost... If this star is 13.7 billions years old - why is that we are able to see it at 6,000 light years ? I wouldn't say I'm dumbbbblol but I skipped a few classes back in the days and I am having such a hard time figuring this one out?”

#### YOKEL13 on Feb 12, 2014 at 00:40:34

“"Light year", a measure of distance, is equal to somewhat less than 6 trillion miles, which is farther than you can go on a tank of gas in your hybrid SUV.”

#### necrodog on Feb 11, 2014 at 15:57:28

“13.7 billion years is how old the star is, 6000 light years is how far away it is from us. Not dumb just two different concepts that can be confused sine they use some similar language.”

#### KYSmiling on Feb 11, 2014 at 13:38:10

“No such thing as a dumb question Boss. To tell the truth Tanzania's answer below helped me out too. I just didn't have the courage to come out with my question. :-)”

#### GreenMurf on Feb 11, 2014 at 12:56:28

“6,000 light years is a measure of distance (like miles - in fact, about 3.5 × 10^16 miles). It's the distance light travels in a year - something travelling at the speed of light would take 6,000 years to travel between us and it. It's a little like looking back in time, since the light we're seeing today left 6,000 years ago.

13.7 billion years is just its age.”

#### TanzaniaTeacher on Feb 11, 2014 at 12:54:43

“Light years defines the amount of time it takes light to reach Earth, ie distance. Years defines the age of the star.”

“Its a more practical approach to understanding how life exists under extreme conditions. At least we can interact with ocean living species rather than guessing what they can look like on other planets. I would leave the latter to film makers with better imaginations.”

“The only thing that makes us special in my opinion is that we are stardust... We are made from the same material that the stars are made of, and for me that's a beautiful thing. and I always say that Life is meaningless expect the meaning we ourselves give it ... There is no purpose, no mission, no meaning for us here on earth that has been assigned to us from some creator ... We create value, and purpose as we evolved as a specie ... And Believe it or not ... we will not be here forever... so let's enjoy the stars and its beauty
