Knock-Knock, anybody home?........................
Cool
Furthest individual star ever spotted is 28 billion lt-yrs away. Not 9.
A planet being of a size like earth means very little when it comes to “life”.
It’s star is a Red Dwarf.
https://en.wikipedia.org/wiki/Red_dwarf
“Red dwarfs are very-low-mass stars.[15] As a result, they have relatively low pressures, a low fusion rate, and hence, a low temperature. The energy generated is the product of nuclear fusion of hydrogen into helium by way of the proton–proton (PP) chain mechanism. Hence, these stars emit relatively little light, sometimes as little as 1⁄10,000 that of the Sun, although this would still imply a power output on the order of 1022 watts (10 trillion gigawatts or 10 ZW). Even the largest red dwarfs (for example HD 179930, HIP 12961 and Lacaille 8760) have only about 10% of the Sun’s luminosity.[16] In general, red dwarfs less than 0.35 M☉ transport energy from the core to the surface by convection. Convection occurs because of opacity of the interior, which has a high density compared to the temperature. As a result, energy transfer by radiation is decreased, and instead convection is the main form of energy transport to the surface of the star. Above this mass, a red dwarf will have a region around its core where convection does not occur.[17]”
That is just the bare beginning of how different, compared to the sun-earth relationship, is the relationship between the “exo-planet” and its star, and the conditions that imparts as to “life” there or not.
But “science” venues love to produce click bait to help support their ad revenue.
The furthest individual star ever spotted is MACS J1149+2223 Lensed Star 1, also known as Icarus. It is located approximately 9 billion light-years away, making it the most distant individual star ever detected.
This star is remarkable because it is only visible due to a quirk of nature, where its light is magnified by the gravity of a massive galaxy cluster, located about 5 billion light-years from Earth. Without this gravitational lensing effect, the star would be too faint to be detected.
Key Facts:
Name: MACS J1149+2223 Lensed Star 1 (Icarus)
Distance: Approximately 9 billion light-years away
Type: Individual star
Magnification: Magnified by the gravity of a massive galaxy cluster.
According to NASA and various scientific sources, the furthest individual star from Earth is Earendel, also known as GN-z11. It is a star that existed within the first billion years after the universe’s birth in the Big Bang. Its light took 13.4 billion years to reach Earth, making it the farthest individual star ever seen to date.
Distance: 13.4 billion light-years from Earth
Age: 13.4 billion years old (when the universe was only 7% of its current age)
Lol. There was another link that said 28 billion. I guess it depends on who you ask
i thought our sun was the most common star in the galaxy?
Our Sun is common but not as common as Red Dwarf stars....................
Yet again the "possible life on exoplanets" spin continues. The most common star turns out to be an ultracool red dwarf star, from which the article pontificates, "This type of star can live 100 times longer than our Sun, making it a prime target in the search for life in the galaxy."
But later the article admits the "Earth-sized planet" orbits so close to the star, a complete revolution occurs every 17 hours. The planet is very likely tidally locked so that one side is always facing the star. This is not conducive for any life on such a planet, much less intelligent life.
28 billion is impossible in a 13 billion year old universe.............
common as in more people are familiar with our sun than any other star.
Also, Red Dwarf stars are prone to powerful eruptions of heated plasma called flares, which can blast orbiting planets with X-rays, ultraviolet light, and a stellar wind (gush of charged particles). These flares are equivalent to more than 100 million atomic bombs.
Which makes ‘life’ kinda difficult...............
“..Which makes ‘life’ kinda difficult...............”
Sounds like the perfect place to send the woke, libs, communists etc. that infest this planet with their cancer.... /s
Thanks Red Badger.

If we could only go and see it.
Even if we had a ship that could accelerate to the speed of light, it would be too slow to get there in a single lifetime..............
So are the large structures supposedly at the limit of detection. They spend more time explaining “impossible” things than anyone.
Time dilation would make it seem much shorter to the occupants.
yep, need to be a generational ship or someone cracks human hibernation.
