If proven, the newly discovered neutron star will be the youngest one known by humanity, beating the current youngest supernova remnant is Cassiopeia A, which is 330 years old that can be found 11,000 light-years away from Earth and can be found within our galaxy.
What is the youngest type of star?
The young M-type star, AU Microscopium (AU Mic), is about half the mass of the sun but only about 12 million years old, compared to the 4.6 billion year age of the sun.
How old is the youngest star in the universe?
Age and distance
| Title | Object | Data |
|---|---|---|
| Oldest star | HD 140283 | 14.5±0.8 billion years |
| Youngest | Stars are being formed constantly in the universe so it is impossible to tell which star is the youngest. For information on the properties of newly formed stars, See Protostar, Young Stellar Object and Star Formation. | |

What is the oldest star?
There is no question that the Methuselah star is old – indeed it is the oldest star in the universe for which there is a fairly precise estimate of its age.
What are the 7 main types of stars?
There are seven main types of stars. In order of decreasing temperature, O, B, A, F, G, K, and M. O and B stars are uncommon but very bright; M stars are common but dim..
Is our sun a red dwarf?
Red dwarfs include the smallest of the stars, weighing between 7.5% and 50% the mass of the sun. Their reduced size means that they burn at a lower temperature, reaching only 6,380 degrees Fahrenheit (3,500 degrees Celsius). The sun, by comparison, has a temperature of 9,900 F (5,500 C).
How long before our sun dies?
Our sun’s death is a long way off — about 4.5 billion years, give or take — but someday it’s going to happen, and what then for our solar system?
What is the rarest star in the universe?
Now astronomers have spotted a bizarre star that may prove to be one of the rarest objects ever, with maybe as few as five or six of them in the galaxy. The object in question is known as J005311, located in the constellation Cassiopeia about 10,000 light-years from Earth.
How long will the universe last?
Vacuum decay might already have begun in some distant place. We won’t see it coming. Not to worry, though. As Mack counsels, whatever it looks like, the end probably won’t be nigh for at least 200 billion years.
Which color star is hottest?
White stars are hotter than red and yellow. Blue stars are the hottest stars of all. Stars are not really star-shaped.
What is the hottest color?
While blue represents cooler colors to most, it is the opposite in fires, meaning they are the hottest flames. When all flame colors combine, the color is white-blue which is the hottest. Most fires are the result of a chemical reaction between a fuel and oxygen called combustion.
Do stars change color as they age?
As stars age, they run out of hydrogen to burn, decreasing the amount of energy they emit. Thus, younger stars can appear bluer while older ones appear more red, and in this way, a star’s color can tell us something about that star’s age.
Can a star live forever?
No. Stars are born, live, and die. This process is called the “life cycle of a star”. Most of the time a star shines, it is in a stage of its life cycle called the main sequence.
What’s older than the universe?
Our Sun is about 4.5 billion years old. Since HD 140283 is a Population II star, it is older. In fact, it is the oldest star with a well-determined age. Because of this, astronomers colloquially call the star “the Methuselah star.” Initial estimates of its age were in excess of 14 billion years.
How old is the universe in 2020?
Universe is 13.8 billion years old, scientists confirm
Obtaining the best image of the infant universe helps scientists better understand the origins of the universe. Scientists estimate the age of the universe by measuring its oldest light.
