Dark Energy Survey

From Astronomy, March 31, 2020: Astronomers have discovered 139 new minor planets orbiting the Sun beyond Neptune by searching through data from the Dark Energy Survey, which is led by Fermilab. The new method for spotting small worlds is expected to reveal many thousands of distant objects in coming years — meaning these first hundred or so are likely just the tip of the iceberg.

From WDRB, March 29, 2020: A study published earlier this month by astronomers at the University of Pennsylvania distinguished more than 100 new planets in our solar system, but estimates show there could be as many as 70,000. These trans-Neptunian objects were found in the data gathered by the Dark Energy Survey, led by Fermilab.

From EarthSky, March 29, 2020: Astronomers analyzed data from the Dark Energy Survey, led by Fermilab, to find over 100 new little worlds in the cold outer reaches of our solar system. These trans-Neptunian objects orbit in the cold outer reaches of our solar system, out beyond Neptune, taking hundreds of years to orbit the sun once.

From Physics World, March 24, 2020: Scientists using the first year of data from the Dark Energy Survey, which is led by Fermilab, establish that there is a correlation between the positions of gravitational lenses — deduced from the stretching of distant galaxies — and gamma-ray photons. A data comparison from gravitational lensing and gamma-ray observations reveals that regions of the sky with greater concentrations of matter emit more gamma rays.

From Forbes, March 16, 2020: Researchers using data from the Fermilab-led Dark Energy Survey have identified more than 300 trans-Neptunian objects — minor planets located in the far reaches of the solar system — including well over 100 new discoveries. The research pioneers a new technique that could help astronomers in the search for undiscovered planets — including the mysterious “Planet 9.”

From Medium, March 11, 2020: Astronomers in the Dark Energy Survey, which is led by Fermilab, report the discovery of 316 minor planets beyond Neptune. Of these, 139 were entirely unknown before this new study, while 245 were seen in earlier observations by DES.

Humans of physics

Enormous scientific collaborations are made up of hundreds upon thousands of individuals, each with their own story. Online collections of profiles, such as Faces of DUNE, the Dark Energy Survey’s Scientist of the Week blog and Humans of LIGO, reveal the sometimes-ignored human sides of scientists.
