dark energy

From Jumbo News, March 31, 2021: Fermilab’s Josh Frieman, Tom Diehl, Antonella Palmese, and Rich Kron as part of the Dark Energy Survey collaboration, have completed scanning a quarter of the southern skies for six years and cataloguing hundreds of millions of distant galaxies.

From Super Interessante, Jan. 31, 2021: A team of researchers from Fermilab and the National Observatory in Brazil used the light of solitary stars to calculate the mass of some of the largest structures in the cosmos — galaxy clusters. In addition to taking the most detailed measurement ever published of intracluster light, the team’s new method of measurement can help further investigate dark matter.

From New Scientist, Jan. 25, 2021: The Big Bang left us the universe — and a major set of mysteries around antimatter, dark matter, dark energy, and cosmic inflation. While the Large Hadron Collider looks at what the laws of physics were like a trillionth of a second after the Big Bang, Dan Hooper, head of theoretical astrophysics at Fermilab, thinks the answers to these puzzles may depend on better understanding that first fraction of a second — even closer to the universe’s beginning.

Mysteries abound in the universe, including the universe’s ultimate fate. In this episode of Subatomic Stories, Fermilab scientist Don Lincoln talks about the observation of a new form of energy called dark energy, which will determine the future of the cosmos.
