    2013 — The galaxy Z8 GND 5296 is confirmed by spectroscopy to be one of the most distant galaxies found up to this time. Formed just 700 million years after the Big Bang, expansion of the universe has carried it to its current location, about 13 billion light years away from Earth (30 billion light years comoving distance).

    en.wikipedia.org/wiki/Cosmic_Calendar

    The Cosmic Calendar is a method to visualize the chronology of the universe, scaling its currently understood age of 13.8 billion years to a single year in order to help intuit it for pedagogical purposes in science education or popular science.

    For any value of the dark energy content of the universe where the negative pressure ratio is less than −1, the expansion rate of the universe will continue to increase without limit. Gravitationally bound systems, such as clusters of galaxies, galaxies, and ultimately the Solar System will be torn apart.

    en.wikipedia.org/wiki/Expansion_of_the_universe

    Because the universe is expanding, is smaller in the past and larger in the future. Extrapolating back in time with certain cosmological models will yield a moment when the scale factor was zero; our current understanding of cosmology sets this time at 13.787 ± 0.020 billion years ago. If the universe continues to expand forever, the scale ...

    For millennia, what today is known to be the Solar System was regarded as the contents of the "whole universe", so advances in the knowledge of both mostly paralleled. Clear distinction was not made until circa mid-17th century. See Timeline of Solar System astronomy for further details on this side.

    HD1 galaxy forms. Earliest quasars. The exoplanet PSR B1620-26 b forms. It is a gas giant, the oldest observed exoplanet in the Universe, orbiting a pulsar and a white dwarf. Visual limit of Hubble Deep Field. Since (known) universe still small in size, galaxy interactions become common as larger and larger galaxies form out of galaxy merger ...
