How old is the Sun 2023
4,500,000,000 years old
Our Sun is 4,500,000,000 years old. That's a lot of zeroes. That's four and a half billion.
What is the death age of Sun
Analyzing the data provided by the Gaia Spacecraft, scientists have concluded that the Sun will reach a maximum temperature at approximately 8 billion years of age, then it will cool down and increase in size, becoming a red giant star. At the age of 1011 billion years, the Sun will reach the end of its life.
How many years does the Sun have left
"This reveals the star's core, which by this point in the star's life is running out of fuel, eventually turning off and before finally dying." Astronomers estimate that the sun has about 7 billion to 8 billion years left before it sputters out and dies. One way or another, humanity may well be long gone by then.
How old is Sun vs Earth
These studies show that the oldest star clusters are about 12 billion years old. The Universe must be older than its stars, so this method establishes a minimum age for the Universe. Similar studies show that the Sun is about 5 billion years old, consistent with the age of the Earth measured by radioactive studies.
What will happen to the sun in 2050
By 2050, that big burning ball of gas is going to be unusually cool, according to a study from the University of California San Diego. Based on 20 years of data collection and observations, a research team led by physicist Dan Lubin calculated that the sun will be 7% cooler — and dimmer — by the mid-century.
Is water older than the sun
By looking at the water on protostar V883 Orion, a mere 1,305 light-years from Earth, scientists found a "probable link" between the water in the interstellar medium and the water in our solar system. That likely means our water is billions of years older than the sun.

How will the sun end
According to ScienceAlert, "In about 5 billion years, the Sun is due to turn into a red giant. The core of the star will shrink, but its outer layers will expand out to the orbit of Mars, engulfing our planet in the process. If it's even still there."
How many years will Sun destroy Earth
By that point, all life on Earth will be extinct. Finally, the most probable fate of the planet is absorption by the Sun in about 7.5 billion years, after the star has entered the red giant phase and expanded beyond the planet's current orbit.
Could we survive without the Sun
With no sunlight, photosynthesis would stop, but that would only kill some of the plants—there are some larger trees that can survive for decades without it. Within a few days, however, the temperatures would begin to drop, and any humans left on the planet's surface would die soon after.

How old is the oldest star
14.45 billion years old
HD 140283, more colorfully called the “Methuselah Star,” is most certainly old and is generally accepted to be one of the oldest known stars. A paper published in 2013 estimated its age to be 14.45 billion years old, with an uncertainty of ±0.8 billion years.
How hot will it be in 2050
They predict that in three decades, more than 100 million Americans will live in an “extreme heat belt” where at least one day a year, the heat index temperature will exceed 125° Fahrenheit (52° Celsius) — the top level of the National Weather Service's heat index, or the extreme danger level.
Will there be an ice age in 2050
"Pink elephant in the room" time: There is no impending “ice age” or "mini ice age" if there's a reduction in the Sun's energy output in the next several decades. Through its lifetime, the Sun naturally goes through changes in energy output.
How old is the water I drink
4.5 billion year-old
Nevertheless, it means that each time you take a sip of water, you are drinking from a 4.5 billion year-old font that dates back to the formation of the Solar System.
Is Sun in middle age
"With an age of around 4.57 billion years, our Sun is currently in its comfortable middle age, fusing hydrogen into helium and generally being rather stable; staid even.
Is water older than Sun
Scientists looking into the origin of life on Earth have claimed that the water present on the planet is very, very old. In fact, a new study has said that it's older than the Sun. The research is based on the discovery of water vapour around V883 Orionis, a young star, 1,305 light years away from Earth.
How old is the oldest water
The world's oldest known water has been discovered by researchers in Canada. A 17-year search of Ontario's Kidd Creek Mine uncovered liquid that has been trapped between rocks for 1.6 billion years, according to the team at the University of Toronto.
What will happen to the Earth in 2025
Ultimately, the general strength of the solar maximum we experience in 2025 will determine just how harsh the solar weather is. It will therefore determine if we experience powerful solar flares or coronal mass ejections, which can then cause issues here on Earth, too.
What will life be like in 1,000 years
In the next 1,000 years, the amount of languages spoken on the planet are set to seriously diminish, and all that extra heat and UV radiation could see darker skin become an evolutionary advantage. And we're all set to get a whole lot taller and thinner, if we want to survive, that is.
Could we survive if the Sun died
With no sunlight, photosynthesis would stop, but that would only kill some of the plants—there are some larger trees that can survive for decades without it. Within a few days, however, the temperatures would begin to drop, and any humans left on the planet's surface would die soon after.
What if the Sun was blue
If you stepped outside for just one second it would be like stepping in an oven. Only hotter the blue sun would instantly burn all the tissues in your body to ashes. And maybe even your bones.
What happens if the Sun died
When the Sun exhausts its store of nuclear fuel, some 5 billion years from now, it will evolve into a bloated red giant, gobbling up Mercury and Venus, and scorching the Earth. After ejecting its outer layers in the form of a colourful planetary nebula, the Sun will then be compressed into a tiny white dwarf star.

What is the youngest galaxy
NASA's Hubble Space Telescope snapped a view of what may be the youngest galaxy ever seen. This "late bloomer" may not have begun active star formation until about 13 billion years after the Big Bang. Called I Zwicky 18 [below, left], the galaxy may be as young as 500 million years old.
