I was just listening to a talk, courtesy of Seifeddine. Allahu Akbar. In the talk, it is mentioned that the Earth fits inside the sun 1.3million times. Can you imagine how huge the sun. is.

The Sun is the star at the center of the Solar System. It is almost perfectly spherical and consists of hot plasma interwoven with magnetic fields. It has a diameter of about 1,392,000 km, about 109 times that of Earth, and its mass (about 2×1030 kilograms, 330,000 times that of Earth) accounts for about 99.86% of the total mass of the Solar System.Chemically, about three quarters of the Sun's mass consists of hydrogen, while the rest is mostly helium. The remainder (1.69%, which nonetheless equals 5,628 times the mass of Earth) consists of heavier elements, including oxygen, carbon, neon, iron, and others.

The Sun's stellar classification, based on spectral class, is G2V, and is informally designated as a yellow dwarf, because its visible radiation is most intense in the yellow-green portion of the spectrum and although its color is white, from the surface of the Earth it may appear yellow because of atmospheric scattering of blue light. In the spectral class label, G2 indicates its surface temperature of approximately 5778 K (5505 °C), and V indicates that the Sun, like most stars, is a main-sequence star, and thus generates its energy by nuclear fusion of hydrogen nuclei into helium. In its core, the Sun fuses 620 million metric tons of hydrogen each second. Once regarded by astronomers as a small and relatively insignificant star, the Sun is now thought to be brighter than about 85% of the stars in the Milky Way galaxy, most of which are red dwarfs. The absolute magnitude of the Sun is +4.83; however, as the star closest to Earth, the Sun is the brightest object in the sky with an apparent magnitude of −26.74. The Sun's hot corona continuously expands in space creating the solar wind, a stream of charged particles that extends to the heliopause at roughly 100 astronomical units. The bubble in the interstellar medium formed by the solar wind, the heliosphere, is the largest continuous structure in the Solar System

All the stars that can be seen in the night sky are part of the Milky Way galaxy, but for the purposes of the astronomical activity of observing the celestial sphere the term "Milky Way" is limited to the hazy band of white light arching around the entire night sky. The light originates from un-resolved stars and other material that lie within the galactic plane. Dark regions within the band, such as the Great Rift and the Coalsack, correspond to areas where light from distant stars is blocked by dark nebulae.

The Milky Way has a relatively low surface brightness, with its visibility being greatly affected by the brightness of the night sky due to light pollution, stray light from the moon, and so forth. It becomes readily visible at limiting magnitudes of +5.1 or better, while showing a great deal of detail at +6.1. This makes the Milky Way difficult to see from any brightly-lit urban or suburban location, but very prominent when viewed from a rural area.

The Milky Way is the galaxy that contains the Solar System. This name derives from its appearance as a dim un-resolved "milky" glowing band arching across the night sky. The term "Milky Way" is a translation of the Latin for "milky road", Via Lactea, in turn derived from the Greek kyklos galaktikos or "milky circle", "milk" ("γάλα") also being the root for the Greek word for galaxy, γαλαξίας (galaxias).

The galaxy has this appearance because it is a disk-shaped structure that is being viewed edge-on. Earth is located within the galactic plane of this disk, around two thirds of the way out from the center, on the inner edge of a spiral-shaped concentration of gas and dust called the Orion–Cygnus Arm. The concept of this faint band of light being made up of stars was proven in 1610 when Galileo Galilei used his telescope to resolve it into individual stars. In the 1920s observations by astronomer Edwin Hubble showed that the Milky Way was just one of around 200 billion galaxies in the observable universe.

The Milky Way is a barred spiral galaxy 100,000-120,000 light-years in diameter containing 200–400 billion stars. The galaxy is estimated to contain at least as many planets, 10 billion of which could be located in the habitable zone of their parent star. Depending on its structure the entire galaxy has a rotational rate of once every 15 to 50 million years. The galaxy is also moving at a velocity of 552 to 630 km per second, depending on the relative frame of reference. It is estimated to be about 13.2 billion years old, nearly as old as the Universe. The Milky Way is part of the Local Group of galaxies.

A RED ROSE IN THE SKY: THE ROSETTE NEBULA When the Heaven shall be cleft asunder, and become rose red, like stained leather. (Surat ar-Rahman, 37) The Arabic expression translated above as "become rose red, like stained leather" is "Wardatan ka addihan." This term compares an image appearing in the sky to a red rose. This description bears a close similarity to red celestial bodies with a plicate appearance, especially the "Rosette Nebula." Nebula is the name given to cloud-like masses of gas in space. Before they become nebulae they are stars, and since these stars are very large, they release gasses into space because of their high internal pressure and temperatures. These eruptions of gas are very large and fast. These gasses then coalesce to form a gas cloud, with a temperature of more than 15,000 0C.1 One type of nebula is known as the "Rosette Nebula" because of its resemblance to a rose. The Rosette Nebula is also a vast cloud of gas and seems to have an area five times greater than that of the full moon. Its true diameter is estimated at 130 light years. A team led by Leisa Townsley, a senior Penn State University researcher in the field of astronomy and astrophysics, examined the Rosette Nebula using the Chandra X-ray telescope. They imaged hundreds of stars in the Rosette Nebula and determined that by crashing into one another stars produce gas at temperatures of 6 million degrees. Townsley describes what she saw: A ghostly glow of diffuse X ray emission pervades the Rosette Nebula and perhaps many other star-forming regions throughout the Galaxy. We now have a new view of the engine lighting the beautiful Rosette Nebula and new evidence for how the interstellar medium may be energized." The existence of this body seen in the illustrations can only be confirmed by high-tech observation equipment. This state of affairs regarding the skies noted in the Qur'an is in great agreement with the findings of present-day astronomy. In one verse of the Qur'an we are told: You do not engage in any matter or recite any of the Qur'an or do any action without Our witnessing you while you are occupied with it. Not even the smallest speck eludes your Lord, either on earth or in heaven. Nor is there anything smaller than that, or larger, which is not in a Clear Book. (Surah Yunus, 61)

The Perfect Equilibrium In The Universe "He Who created the seven heavens in layers. You will not find any discrepancy in the creation of the All-Merciful. Look again-do you see any gaps? Then look again and again. Your sight will return to you dazzled and exhausted!" (Qur'an, 67:3-4) The billions of stars and galaxies in the universe move in perfect equilibrium in the paths set out for them. Stars, planets and satellites rotate not only around their own axes but also together with the systems of which they are an integral part. Sometimes, galaxies containing 200-300 billion stars move across each others' paths. Yet amazingly, no collisions take place that might damage the great order in the universe. This miracle is something over which all of us should reflect. In the universe, the concept of speed assumes giant dimensions when compared to earthly measurements. Stars, planets, galaxies and conglomerations of galaxies whose numerical properties can only be conceived by mathematicians-weigh billions or trillions of tons, and move through space at extraordinary speeds. For example, the Earth rotates at 1,670 kmph. If we consider that the fastest-moving bullet today possesses an average speed of 1,800 kmph, we can see how fast the Earth is moving, despite its enormous size and mass. The speed of the Earth as it orbits the Sun is some 60 times faster than a bullet: 108,000 kmph. If we were able to construct a vehicle capable of moving at that speed, it would be able to circumnavigate the Earth in 22 minutes. These figures apply only to the Earth. Those for the Solar System are even more fascinating. The speed of that system is such as to exceed the bounds of reason: The larger the systems in the universe, the greater their speed. The Solar System's speed of orbit around the centre of the galaxy is 720,000 kmph. The Milky Way, with its 200 billion or so stars, moves through space at 950,000 kmph. There is no doubt that there is a very high risk of collisions in such a complicated and fast-moving system. Yet nothing of the sort actually happens and we continue with our lives in complete safety. That is because everything in the universe functions according to the flawless equilibrium set out by Allah. It is for this reason that, as stated in the verse, there is no "discrepancy" in the system.

Ever heard of Betelgeuse I hadn't realised how immensely huge it is.

The relative sizes of our Sun, the orbits of the planets and Betelgeuse are completely accurate! The numbers:

Diameter of the sun: 1.39 million km
Orbit of Earth: 300 million km
Orbit of Jupiter: 1556 million km
Diameter of Betelgeuse: 2100 million km

VY Canis Majoris (VY CMa) is the largest known star and also one of the most luminous. It is a red hypergiant in the constellation Canis Major. It is 1800–2100 solar radii (8.4–9.8 astronomical units) in radius, about 3.0 billion km (1.9 billion mi) in diameter, and about 1.5 kiloparsecs (4,900 light-years) distant from Earth. Unlike most hypergiant stars, which occur in either binary or multiple star systems, VY CMa is a single star. It is categorized as a semiregular variable and has an estimated period of 2,000 days. It has an average density of 5 to 10 mg/m3.

Placed at the center of our solar system, VY Canis Majoris's surface would extend beyond the orbit of Saturn, although some astrophysicists disagree about the star's stated radius, suggesting it is smaller: merely 600 times the radius of the Sun, which would extend past the orbit of Mars.

This is the star R1361a found in the constellation of Dorado in the Large Magellanic Cloud.

The star has a mass of around 265 times that of our Sun, but it could have been even larger at the time of its birth - maybe as much as 320 times that of the Sun.

We show you a rough visualisation of these kinds of scales from the Earth, past the Sun, up to R136a1. Amazing.

Larger stars exist (in terms of size, such as VY Canis Majoris)

Can you imagine how big VY Canis Majoris is?
