In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what is the approximate number of stars in the milky way. Here are 44 of the best facts about How Many Stars In The Observable Universe and The Total Number Of Stars In The Observable Universe Is About I managed to collect.

population i stars are found in what area of the milky way?

All things observable--the stars, planets and galaxies that can be seen today--make up just 4% of the universe. The other 96% is made of stuff astronomers can't see, detect or even comprehend.
The largest galaxy in the observable universe is elliptical galaxy, IC 1101. It has 100 trillion stars and is 6 million light years across! By comparison, the Milky way has a mere 100 billion stars and is 120,000 light years across.
That, although there are more stars in the universe than the grains of sand on Earth, there are more atoms in your body than all the stars in the observable universe.
More than 4/5 of the single points of light we observe in the night sky are actually two or more stars orbiting together.
The first generation of stars in the Universe were all several thousand times more massive than the Sun and were made of hydrogen, helium, and trace amounts of lithium. All the heavier chemical elements were formed within their cores. One of these stars was observed for the first time in 2015.
In 2004, a Magnetar (a type of a Neutron Star with a powerful magnetic field) had a large gamma ray burst which briefly expanded the ionosphere. It is thought to be the largest explosion observed in the galaxy by humans since the supernova observed by Johannes Kepler in 1604.
In 1604 Johannes Kepler began to observe a supernova. It is sometimes called Kepler's Star and it occurred in the Milky Way. The supernova's official name is SN 1604. It faded from being visible by the naked eye after a year.
The largest star ever observed, UY Scuti, has a radius of 739,000,000 miles. Or, if it were in the middle of our Solar System, it would almost reach the orbit of Jupiter.
The existence of Binary Black Holes were confirmed when they spiralled and merged, releasing around 3 solar masses of gravitational energy - more than the combined power of all light radiated by all the stars in the observable universe put together
UY Scuti, the largest star observed so far. If it was placed at the center of our solar system, it would engulf every planet closer than Saturn.

What is true about stars observable?

You can easily fact check it by examining the linked well-known sources.

His observations led him to theorize that double stars might be binary sidereal systems operating under mutual gravitation attraction.

There are 30 stars going supernova, every second, in the observable universe - source

Scientists have estimated the number of stars in the observable universe to be "70 thousand million, million, million." However, if you count all the molecules in drops of water, it takes only 10 drops for the number of H2O molecules to equal the number of stars in the sky. - source

The approximate number of all the stars in the observable universe is 1 septillion, or 1 followed by twenty-four zeros

Joseph von Fraunhofer using his skills as a glass maker to create very pure prisms, which allowed him to observe 574 dark lines in a seemingly continuous spectrum, that allowed to identify the stars and other space objects composition. - source

When do stars form in the milky way?

Makemake's lack of moons and sunlight makes it difficult to study. Recently Makemake passed by a star, an event known as a stellar occultation, giving astronomers an opportunity to observe in detail. Scientists expected this dwarf planet's atmosphere to be similar to that of Pluto, however, they found it has no atmosphere.

How many stars are there in the observable universe?

There is a newly discovered planet that is 1/4th the size of its star, making it the smallest difference between a planet and star yet observed.

The LMC contains a highly active starbirth region called the Tarantula Nebula. It is a part of a larger cloud of gas and dust. Its high rate of star formation may be caused by compression of interstellar gas and dust by the collision of the cloud with the interstellar medium. The LMC was also a host to a supernova (SN1987A) and was the brightest observed in over four centuries.

There are 2 billion planets and 2 billion stars in our galaxy. There are 2 trillion galaxy’s in our observable universe. The rest of our universe is sextillion times bigger than the observable.

The Tabby's Star, a star which behave oddly under observation. Hypothesized explanations include an Artificial Megastructure created by an extra-terrestrial civilization

About IC 1101, the single largest galaxy that has ever been found in the observable universe. Just how large is it? At its largest point, it extends about 2 million light-years from its core, and it has a mass of about 100 trillion stars.

Interesting facts about stars observable

The Monument to the Great Fire of London, built between 1671 & 1677 and 62m (202') tall, was designed by Robert Hooke to be a big telescope. Originally, lenses would have slotted in at either end and an observer, standing in the lab, could take measurements of the stars using a special eyepiece.

There are ~10 million times more viruses on Earth than there are stars in the observable universe.

The SN 1006 supernova was the brightest star event in recorded history. Exceeding roughly sixteen times the brightness of Venus, this 'guest star' was described by observers across China, Japan, Iraq, Egypt, and Europe. Some reports state it was clearly visible in the daytime.

Galileo suggested that the stars and planets did not revolve around the earth because he observed "stars following Jupiter" and the crescent phases of Venus

There are 2 billion stars and 2 billion planets in our galaxy. There are 2 trillion galaxy’s in our observable universe. The rest of space is sextillion times bigger then the observable universe

How many stars are there in the observable universe quizlet?

DES16C2nm, a superluminous supernova that occurred 10.5 billion years ago is the most distant star explosion ever observed

22 years ago today, space station Mir was hit during a docking exercise. Mir started leaking air and spinning out of control. The crew had to estimate the spin manually by observing the movement of stars to counteract it. Docking was attempted solely via a poor video link with radar off.

22 years ago today, space station Mir was hit by the Progress spacecraft during a radarless docking exercise that relied only on a poor video link. With smashed solar panels, leaking air and spinning out of control, the crew had to counteract the spin by observing the movement of stars.

There are 200 billion stars and 200 billion planets in our galaxy alone! There are 2 trillion galaxy’s in our observable universe . The rest of the universe is sextillion times bigger than the observable and is expanding faster than the speed of light meaning we will never see them.

The original "guest stars" were actual stars that went nova. Ancient observers would note a star that appeared for a brief time, then vanished.

Flat Earthers try to explain the shifting constellations observed by people all around the world by believing that the stars and sun and other objects are just a few thousand miles above the Earth hence 'shifting constellations'.

A 19th century astronomer was fed up with the quality of his male assistant's work, and threatened that his maid could do better. He hired her, and eventually many other women, because they did do better work. They helped him catalogue the entirety of the stars observable at the time.

Chinese Astronomers observed a supernova explosion in 1054 A.D, which appeared as bright star that would be visible even in day for 2 years

The number of atoms in a grain of sand is comparable to the number of stars in the observable universe.

When Neil deGrasse Tyson first saw automatic sliding doors on Star Trek, he "was certain that such a mechanism would not be invented during my years on Earth. Star Trek was taking place hundreds of years hence, and I was observing future technology."

Star KIC 84628532 has been observed as having large, irregular changes in brightness. This is unprecedented star behavior, and hypotheses range from a swarm of comets to aliens.

Discovered in 2009, Seque 2 is the least massive galaxy in the observable universe. It has around 1000 stars (as compared to the billions of stars in the Milky Way). This grouping of stars has another odd characteristic- they are some of the oldest stars we've discovered - 12-12.5 billion years old.

"Red Shift" from stars isn't from repeatedly observing the same stars, but by observing 'absorption lines' of the same element across multiple stars! [slide 19]
