00:04This is what is known as the Sears Field, or a particular area of space captured by the James Webb
00:09Space Telescope.
00:10It shows myriad distant old galaxies, but this one right here might just be the oldest.
00:15It's called Maisie's Galaxy, and it doesn't look like much, just a red splotch on the black backdrop of the
00:20vacuum of space.
00:22But experts say that's expected.
00:23That's because the universe is constantly expanding, meaning these distant objects are literally getting further away,
00:29causing their light to be stretched.
00:31This is called redshift, and causes extremely distant objects to appear as red, elongated entities like this one.
00:37So how old is the oldest galaxy ever discovered?
00:39Experts say based on the photometry of the galaxy, the light we are seeing likely traveled for some 13.4
00:45billion years before it reached us,
00:47meaning the galaxy came into existence just 390 million years after the Big Bang.
00:52Another extremely old galaxy in the same field is called Sears 93316.
00:57It was once thought to have been formed only 250 million years after the Big Bang.
01:01However, spectroscopic follow-up revealed it was actually created around 1.2 billion years after the universe creating event.
01:09So see which Jeżeli has be evicted remarkable将, and will you not be less?
01:14Many other films may have shown the fact that each other is becoming more than Heidi Mount Prozent.
