@@danieljohnmorris Firstly do you mean the diameter size or mass? In terms of mass those first stars would have had masses hundreds of times greater than the sun, possibly with up to 1,000 solar masses. Secondly they would have been composed of mostly hydrogen with some helium and lithium. The other heavier elements like carbon, oxygen nitrogen and others up to iron would have been formed during the lives of these stars through the fusion process. Once these stars went supernova, elements heavier than Iron like gold, silver and uranium would have been formed. The supernova would have produced enough heat, pressure and neutrons that a quick burst of fusion and production of heavier elements could happen. Over millions of years these supernova enriched the universe with these elements, allowing planets to form. Today stars are still composed of mostly hydrogen and helium, but they also have some of the heavier elements as well.

Information about Stephenson 2-18 Stephenson 2-18 (abbreviated to St2-18), also known as Stephenson 2 DFK 1 or RSGC2-18, is a red supergiant (RSG) or possible extreme red hypergiant[2] (RHG) star in the constellation of Scutum. It lies near the open cluster Stephenson 2, which is located about 5.8 kiloparsecs (19,000 light-years) away from Earth in the Scutum-Centaurus Arm of the Milky Way galaxy, and is assumed to be one of a group of stars at a similar distance, although some sources consider it to be an unrelated red supergiant.[5][6] It is among the largest known stars, one of the most luminous red supergiants, and one of the most luminous stars in the Milky Way. Stephenson 2-18 together with its supposed parent cluster Stephenson 2 (upper left), viewed by the Two-Micron All Sky Survey. Observation data Epoch J2000 Equinox J2000 Constellation Scutum Right ascension 18h 39m 02.3709s[1] Declination −06° 05′ 10.5357″[1] Characteristics Evolutionary stage Red supergiant, possible extreme red hypergiant[2] Spectral type ~M6[3] Apparent magnitude (G) 15.2631±0.0092[1] Apparent magnitude (J) 7.150[4] Apparent magnitude (H) 4.698[4] Apparent magnitude (K) 2.9[4] Astrometry Radial velocity (Rv) 89[5] km/s Proper motion (μ) RA: −3.045±0.511[1] mas/yr Dec.: −5.950±0.480[1] mas/yr Parallax (π) −0.0081 ± 0.3120 mas[1] Distance 18,900[6] ly (5,800[6] pc) Details Radius 2,150[7][a] R☉ Luminosity 436,516[7] (90,000[8]-630,000[6][b]) L☉ Temperature 3,200[7] K Other designations Stephenson 2-18, Stephenson 2 DFK 1, RSGC2-18, 2MASS J18390238-0605106, IRAS 18363-0607, DENIS J183902.4-060510, MSX6C G026.1044-00.0283 Stephenson 2-18 has an estimated radius of around 2,150 solar radii (1.50×109 kilometres; 10.0 astronomical units), which would correspond to a volume nearly 10 billion times that of the Sun. Taking this estimate as correct, it would take nearly 9 hours to travel around its surface at the speed of light, compared to 14.5 seconds for the Sun.[9] If placed at the center of Earth's Solar System, its photosphere would engulf the orbit of Saturn.

Re: Size and relativity to c (speed of light) reminded me of something I thought of before. When looking at an image of something light years across, like a galaxy, are we seeing the shape of the galaxy as it truly is? Say it's 200k ly across and we're seeing it more from the edge from our perspective. If the light from the nearest edge is 200,000 light years closer to us, wouldn't the light from the furthest edge be 200,000 years old, thus not actually appear the way it seems?

The stars that are further away, say 100,000 ly, the light from those stars took 100,000 years more to reach us than the front stars. So doesn't it stand to reason that those stars that are farther, need to be re-positioned in order to give an accurate image relative to the closer stars? Do you understand what I'm asking?

@@SuperScottCrawford Yep, it needs a repositioning but not...much. For Sun the galactic year, the time to make a complete circle around the galactic center is... 225 to 250 million terrestrial years. The gravitational effects also propagate with the speed of light, but the gravity well of the galaxy as a whole is already there for the individual stars to follow. So the (relative) stellar speeds are of no consequence on the bigger scale, the shape doesn't change too much if you observe a big, but slow rotating object and you want to compare with a snapshot at a certain "galactic Greenwich time".
