What is the oldest thing in the universe
Astronomers have discovered what may be the oldest and most distant galaxy ever observed. The galaxy, called HD1, dates from a bit more than 300 million years after the Big Bang that marked the origin of the universe some 13.8 billion years ago, researchers said on Thursday.

What kind of star is our sun
yellow dwarf star
The Sun is a 4.5 billion-year-old yellow dwarf star – a hot glowing ball of hydrogen and helium – at the center of our solar system. It's about 93 million miles (150 million kilometers) from Earth and it's our solar system's only star. Without the Sun's energy, life as we know it could not exist on our home planet.
How many stars in the universe
200 billion trillion stars
There are approximately 200 billion trillion stars in the universe. Or, to put it another way, 200 sextillion. That's 200,000,000,000,000,000,000,000! The number is so big, it's hard to imagine.
What is the oldest known star
Methuselah
Methuselah: The oldest star in the universe | Space.
What is the oldest star
Methuselah
Methuselah is believed to be the oldest star in the entire known universe, having formed over 14 billion years ago. Its age makes it older than the universe itself. Another mystery added to the list of those involving our universe. The subgiant is definitely old.

Which star is older
the Methuselah star
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.
Is our sun a rare star
The Short Answer:
Our Sun is an average sized star: there are smaller stars and larger stars, even up to 100 times larger. Many other solar systems have multiple suns, while ours just has one.
How hot is our sun
5,772 KSun / Surface temperature
Are there 100 billion stars
About the Universe
Our Sun is one of at least 100 billion stars in the Milky Way, a spiral galaxy about 100,000 light-years across.
How many galaxies exist
2 trillion galaxies
One such estimate says that there are between 100 and 200 billion galaxies in the observable universe. Other astronomers have tried to estimate the number of 'missed' galaxies in previous studies and come up with a total number of 2 trillion galaxies in the universe.

Which star is older than universe
In 2013, a measurement of the "Methuselah Star" suggested that it is 14.45 billion years old — older than the age of the Universe.
Is the Sun older than the universe
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.
Is the Sun a baby star
The Sun is a yellow dwarf star, which means it is a medium size star. It is believed to be over 4 billion years old. The Sun spins slowly on its axis as it revolves around the galaxy. The center, or core, of the Sun is very hot.
What is the rarest stars
A newly discovered star just 773 light-years away belongs to one of the rarest categories in the Milky Way. J1912-4410 is a white dwarf pulsar, a type of star so rarely seen that only one other is known in the entire galaxy.
Is lava Hotter Than the Sun
Lava is indeed very hot, reaching temperatures of 2,200° F or more. But even lava can't hold a candle to the sun! At its surface (called the "photosphere"), the sun's temperature is a whopping 10,000° F! That's about five times hotter than the hottest lava on Earth.
Is sun hotter than ever
The Sun is getting hotter, adding heat to the global warming that has been linked to greenhouse gases that trap heat in the atmosphere. Solar radiation reaching the Earth is 0.036 percent warmer than it was in 1986, when the current solar cycle was beginning, said a study published on Friday in the journal Science.
Which galaxy has 1 trillion stars
spiral galaxy UGC 2885
One of the most photogenic is the huge spiral galaxy UGC 2885, located 232 million light-years away in the northern constellation, Perseus. It's a whopper even by galactic standards. The galaxy is 2.5 times wider than our Milky Way and contains 10 times as many stars, about 1 trillion.
What has 200 billion stars
Milky Way Galaxy
Milky Way Galaxy | AMNH. The Milky Way is the galaxy in which our Solar System lives. There are more than 200 billion stars in our spiral galaxy, and our Sun is just one of them. Even if you traveled at the speed of light, it would take you about 100,000 years to get across the Milky Way.
Are there 12 galaxies
There are about 51 galaxies in the Local Group (see list of nearest galaxies for a complete list), on the order of 100,000 in the Local Supercluster, and an estimated 100 billion in all of the observable universe.
Is the universe Unlimited
There's a limit to how much of the universe we can see. The observable universe is finite in that it hasn't existed forever. It extends 46 billion light years in every direction from us. (While our universe is 13.8 billion years old, the observable universe reaches further since the universe is expanding).
Who is world’s oldest star
Methuselah is believed to be the oldest star in the entire known universe, having formed over 14 billion years ago.
What is our oldest star
the Methuselah star
HD 140283 (also known as the Methuselah star) is a metal-poor subgiant star about 190 light years away from the Earth in the constellation Libra, near the boundary with Ophiuchus in the Milky Way Galaxy.
