More Than Stars: The Milky Way’s Dust Mapped In 3D For The First Time Ever (Synopsis)

“Things need not have happened to be true. Tales and adventures are the shadow truths that will endure when mere facts are dust and ashes and forgotten.” -Neil Gaiman Wherever we look in the night sky, we don’t just observe the background sources of light shining our way, but also the effects of all the … Read moreMore Than Stars: The Milky Way’s Dust Mapped In 3D For The First Time Ever (Synopsis)

Universe’s largest structure caught in the act of forming (Synopsis)

“On a cosmic scale, our life is insignificant, yet this brief period when we appear in the world is the time in which all meaningful questions arise.” -Paul Ricoeur When it comes to the largest bound cosmic structures, it doesn’t get any bigger than galaxy clusters. Unless, that it, you consider when multiple galaxy clusters … Read moreUniverse’s largest structure caught in the act of forming (Synopsis)

Ask Ethan: Does Dark Energy Mean We’re Losing Information About The Universe? (Synopsis)

“The history of astronomy is a history of receding horizons.” -Edwin Hubble As you look to greater and greater distances, you’re looking back in time in the Universe. But thanks to dark energy, what we can see and access today isn’t always going to be accessible. As galaxies grow more distant with the accelerated expansion … Read moreAsk Ethan: Does Dark Energy Mean We’re Losing Information About The Universe? (Synopsis)

Cosmic superclusters, the Universe’s largest structures, don’t actually exist (Synopsis)

“It’s the gravity that shapes the large scale structure of the universe, even though it is the weakest of four categories of forces.” -Stephen Hawking Galaxies don’t just exist in isolation in our Universe, but are often found bound together as a part of even grander structures. Our own Milky Way is bound in a … Read moreCosmic superclusters, the Universe’s largest structures, don’t actually exist (Synopsis)

Faintest galaxies ever seen explain the ‘missing link’ in the Universe (Synopsis)

“The problem is, you’re trying to find these really faint things, but you’re looking behind these really bright things. The brightest galaxies in the universe are in clusters, and those cluster galaxies are blocking the background galaxies we’re trying to observe.” -Rachael Livermore One of the biggest puzzles in science is exactly how the Universe … Read moreFaintest galaxies ever seen explain the ‘missing link’ in the Universe (Synopsis)
