space is deep imo

the Sagan stuff in the first ep of Cosmos is still painfully beyond my genuine comprehension, think of how vast one galaxy is and then multiply out by a vast number of galaxies at vast distances from one another, i think it is literally incomprehensible in any sense other than mathematically

if possible for Andromeda to be more luminous, it would appear roughly six times larger than our moon. But at 2.5 million light-years from Earth, the galaxy is not as easily seen as the crescent in our sky—which is only 238,900 miles (384,400 kilometers) from Earth.

“As a side note, its worth noting that the "size" of the Andromeda galaxy only really corresponds to that part of Andromeda that everyone is familiar with,” says McConnachie. “That part of Andromeda is most of the disk, which is where the overwhelming majority of the stars are located. However, if you include the much fainter outer parts of the galaxy, then the actual spatial extent of Andromeda is much, much, much larger.”

The full extent of Andromeda, according to McConnachie, is at least 20 degrees across, or the equivalent of more than 40 full moons!

...convinced the researchers that the bright flash was probably caused by a star being torn apart and spaghetti-fied.

It's really hard to tell / define how big it really is because it is so big

it seems that UY Scuti might be a better contender for largest known star at this point

UY Scuti is a bright red supergiant and pulsating variable star in the constellation Scutum. It is a current and leading candidate for being the largest known star by radius and is also one of the most luminous of its kind.[citation needed] It has an estimated radius of 1,708 solar radii (1.188×109 kilometres; 7.94 astronomical units); thus a volume nearly 5 billion times that of the Sun. It is approximately 2.9 kiloparsecs (9,500 light-years) from Earth. If placed at the center of the Solar System, its photosphere would at least engulf the orbit of Jupiter.
