A slice through largest-ever three-dimensional map of the Universe. Earth is at the left, and distances to galaxies and quasars are labelled by the lookback time to the objects (lookback time means how long the light from an object has been traveling to reach us here on Earth). The locations of quasars (galaxies with supermassive black holes) are shown by the red dots, and nearer galaxies mapped by SDSS are also shown (yellow). The right-hand edge of the map is the limit of the observable Universe, from which we see the Cosmic Microwave Background (CMB) – the light “left over” from the Big Bang. The bulk of the empty space in between the quasars and the edge of the observable universe are from the “dark ages”, prior to the formation of most stars, galaxies, or quasars.

Astronomers Create Largest 3D Map of the Universe

May 24, 2017

A team of astronomers working with the Sloan Digital Sky Survey (SDSS) created the largest ever three-dimensional map of the universe. Released along with an accompanying study, the astronomers say the new map is the first to exclusively use the positions of quasars to chart the significant structures of the Universe. “Because quasars are so […]

X Marks the Spot; New Radiation Monitor on ISS; 3D Astronomical Map

July 20, 2016

X Marks the Center of the Milky Way When we hear “X marks the spot,” many of us might think of old pirate maps and where treasure is supposedly buried. But “X marks the spot” could also have more of a cosmic meaning, thanks to a new study published in the Astronomical Journal. The study’s […]

Are We Real or Holograms?, Fortified Seasonings Fight Nutrient Deficiencies, Send Cancer Cells into Space for Radiation Study, Does Marijuana Use Reduce Domestic Violence?

August 27, 2014

Are We All Real or Are We Just Holograms? Most, if not all of us, think of ourselves as real, living and breathing people, actual 3D physical objects.  But according to quantum physics, all of us and our entire world and universe could, in reality, just be a simple 2D hologram, a kind of optical […]

Astronomers Capture 3D Images of Mysterious Intergalactic Matter

April 30, 2014

For the first time, 3D images have been captured of a cosmological entity called the intergalactic medium (IGM).  Until now, the structure of IGM had been theoretical. The discovery could provide astronomers with a new understanding of galactic and intergalactic dynamics. The images were captured with an instrument built at the California Institute of Technology […]
