Pinning Down the Distance to the Farthest Galaxy Ever Observed
Take a journey into the furthest reaches of our cosmos and learn about the most distant galaxy we have ever observed.

Most galaxies take significant fractions of the age of the universe to noticeably change. Others transform themselves in the first two billion years of the universe. How does this happen?
The night sky is now destined to change due to plans which involve placing thousands of satellites into low Earth orbits. Is there a cause for concern?
The early universe is a period of intense star formation across nearly all galaxies. Is it possible tell these galaxies apart from each other, when the universe was less than a few billion years old?
Massive galaxies arise by the time the universe is less than half its current age. Wait four billion more years, and by how much do these galaxies grow? The answer may surprise you.
Constraining physical parameters in a cosmological survey is often computationally expensive, especially when considering more than one survey at a time. The authors of this paper offer a simple method to reconstruct parameter distributions in a fraction of the time needed for most high-performance computers.
