Mar 7th: Yes, Scientists DO Look at the (Dark Energy Survey) Data
Every time I get the digital “why can’t you scientists just look at the data” lecture, I wonder what people think scientists do. All we do is look at data including accelerating rate of expansion of the Universe…
Feb 13th: Challenges to Dark Energy
It’s been over 20 years since astronomers first discovered that the expansion of the Universe is accelerating thanks to dark energy. And in these decades, astronomers still don’t have much evidence for what could be causing the increased expansion rate. Maybe there’s something else going on to explain it.
Oct 8th: 10 Years Of The Dark Energy Camera
The Dark Energy Camera (DECam) is an extremely powerful imager mounted on the Victor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory in Chile. DECam has 570 megapixels that cover 3 square degrees of the sky. In this podcast, Alistair Walker describes the history of the Dark Energy Camera, its first 10 years in operation, and looks to what the future holds.
Apr 18th: Big Qs Update: Dark Matter, Dark Energy, Etc.
Knowledge moves forward, and so, we must move with it. Today we’ll give you an update on some of the most fascinating, fast-changing topics in astronomy, astrophysics and cosmology.
Oct 27th: Dark Energy Seems To Be Changing Over Time
Astronomers working with the NASA’s Chandra X-Ray Observatory and ESA’s XMM-Newton have developed a technique to watch quasars and track the expansion of the Universe. More at #365DaysOfAstro
Feb 13th: The Dark Energy Survey Data Release #2

Jan 12th: The Last Night of the Dark Energy Survey
The Dark Energy Survey started in 2013 to map dark energy over 5000 square degrees of sky. The survey concluded on January 9th, 2018 with its last night of observing. Listen to the conversation at the end of this journey.
Jul 17th: How does dark energy accelerate the universe?
What is the cosmological constant? How is the expansion of the universe related to quantum fields? How does a vacuum energy produce accelerated expansion?
