On the trail of the mysteries of the Universe: watch this space!

It’s the largest survey of the early Universe to date – collecting data and making it available to researchers and enthusiasts alike. It could help solve the mystery of dark energy in the Universe: https://www.uni-goettingen.de/en/3240.html?id=8198

"We present the first publicly released catalog of sources obtained from the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX). #HETDEX is an integral field spectroscopic survey designed to measure the Hubble expansion parameter and angular diameter distance at 1.88 < z < 3.52 by using the spatial distribution of more than a million Lyα-emitting galaxies over a total target area of 540 deg^2": https://iopscience.iop.org/article/10.3847/1538-4357/aca962 -> https://www.tacc.utexas.edu/-/hetdex-reveals-galaxy-gold-mine-in-first-large-survey

"The one thing that I love about #astronomy is that it allows us to step outside of our daily lives and look at the bigger picture for where we came from," said Gebhardt, who leads Dark Energy Explorers, a research project based at the University of Texas in Austin.

Their goal is to create the first #map of the #universe.

"This is a huge experiment," he said.
So much so, they're turning to the public for help.

Isaiah Pipkin is an undergraduate double-majoring in astronomy and physics, who's working on the project.

"Since they did a blind survey of the sky, we have millions of sources that are unclassified," Pipkin said.

Through an app called #Zooniverse or by logging on with a computer, anyone can join Dark Energy Explorers, part of the Hobby-Eberly Telescope Dark Energy Experiment ( #HETDEX ).

After a brief online #tutorial, anyone can look at images captured by the team's telescope and identify what they are.
