Just because matter is visible doesn’t mean it’s easy to see.

Scientists have proposed new instruments that would use spectroscopy to decode dark matter, dark energy and cosmic inflation.
Collaborators on the Dark Energy Spectroscopic Instrument breathe a sigh of relief as they successfully restart the state-of-the-art experiment.
From URA.org (University Research Association), June 30, 2022: Matthew Portman’s research on the Dark Energy Spectroscopic Instrument was accepted by the URA’s Visiting Scholars Program Review Panel and was awarded funding to work at Fermilab where he worked with Dr. Antonella Palmese, a former Visiting Scholar herself. Portman’s curiosity for gravitational waves and coding knowledge allowed him to merge both physics and computer science while at Fermilab.
From Science Times, January 31, 2022: The Hubble Space Telescope captured a stunning image of the Phoenix constellation with a group of galaxies collectively known as NGC that is approximately 450 million light-years away from Earth. The picture of three galaxies interacting was taken using a combination of the Hubble’s Advanced Camera for Surveys that includes the Dark Energy Survey Camera (DECam), developed and tested at Fermilab.
After less than a year of data taking, DESI has already mapped out more galaxies than all previous 3D surveys combined — and it’s just getting started.
From Brazil Culture, November 3, 2021: Fermilab’s Marcelle Soares Santos was included in this impressive exhibit of “Women in Science” curated by the Catavento Museum of São Paulo. The exhibition was conceived to bring to light women who acted and act in a significant way for scientific research and development, presenting, in monumental panels, 12 scientists from different times, nationalities and areas of knowledge.

From Phys.org, August 24, 2021: Using the powerful 570-megapixel Dark Energy Camera (DECam) created and tested by Fermilab for the DES, astronomers have discovered an asteroid with the shortest orbital period of any known asteroid in the Solar System.
From Kathimerini (Greece), June 14, 2021: A multinational team of 400 researchers from 25 research centers in seven countries announced the results of the DES study that looked at 226 million galaxies and thousands of supernova explosions. The DES measurements, like those of other similar galactic surveys, informed us that the current universe is less dense than our model predicts.
From Yahoo, May 30, 2021: Scientists from the Dark Energy Survey collaboration have just released the best dark matter map yet, but it’s not answering every question — if anything, the cosmos may be more mysterious than ever.
