... Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS). The study shows that 26 of the host galaxies bear no tell-tale signs of collisions with neighbors, such as distorted shapes.
The quasars found in normal-looking galaxies are fainter than those powered by collisions betw...

Astronomers use it often, along with its larger buddy, kiloparsec! In extragalactic/cosmology scales, even megaparsec is quite useful sometimes.

The GLEAM survey, short for Galactic and Extragalactic All-sky MWA, is a radio astronomy project that mapped the entire sky visible from Western Australia using the Murchison Widefield Array (MWA) telescope.
New 'radio map' of Milky Way reveals where stars are born and die
The Milky Way appears as a dusty band of stars, but by observing its radio frequencies a different view can bee seen, revealing parts of the galaxy hidden from sight.

NASA's #habitableworldsobservatory
building a #superhubble in the race to answer fundamental questions about life in the Universe, the place of humanity in the cosmos, and where explorers could dare to go next✨🧪🔭☄️ #exoplanet #extragalactic
NASA’s Habitable Worlds Observatory will do more than hunt for life in the 2040s.

This summer scientists put forward 100 ideas for the ‘scope including planetary defense, studying Venus, and even observing individual stars in distant galaxies.

How about not to naked eye though - to early telescopes the extragalactic environment would look different, no?

And managed to bring in the grand theme of robots and their own psychohistory (Zeroth Law) too

Plus the whole EXO thing (Asimov wanted extragalactic aliens but couldn't work the story)

Plus Daddy Ebling Mis (Siddig El Faddil)

Also anything directed by Roxann Dawson will kick arse

Starting after 2016 he started trying to publish in planetary science instead of his home field (extragalactic, black holes...). His lack of knowledge and skill (but not lack of confidence) in those areas since ~2018 are so stunningly bad, I also wonder why.
