Saturday Citations: The Dark Energy Survey; the origins of colorblindness; the evolution of heads
The Dark Energy Survey took an entire decade to produce a value for the cosmological constant—and it's smaller than you might think! There were other stories as well, including one about primeval black holes, and because ...
Another example of a fantastic Einstein ring
The most evocative astronomy images take us across space and time to stars and galaxies billions of light-years away. Nestled at the center of this one, taken by the Hubble Space Telescope, is a collection of three galaxies. ...

Dark energy is one of the biggest puzzles in science and we're now a step closer to understanding it
Over ten years ago, the Dark Energy Survey (DES) began mapping the universe to find evidence that could help us understand the nature of the mysterious phenomenon known as dark energy. I'm one of more than 100 contributing ...

Scientists flip around gravitational-wave data analysis: Have LIGO and Virgo detected a merger of dark-matter stars?
Gravitational waves are ripples in the fabric of spacetime that travel at the speed of light. These are produced in some of the most violent events in the universe, such as black-hole mergers, supernovae, or the Big Bang ...

A method to straighten curved space-time
One of the greatest challenges of modern physics is to find a coherent method for describing phenomena, on the cosmic and microscale. For over a hundred years, to describe reality on a cosmic scale we have been using general ...
