Latest about Dark Energy

The Dark Energy Camera imaged 10 selected areas of the sky called deep fields. The multiple images of each provided astronomers with a glimpse of distant galaxies and how they are distributed throughout the universe.

Did a dark energy discovery just prove Einstein wrong? Not quite.

By Paul Sutter published

The Dark Energy Survey just released its most comprehensive results. But did they really prove Einstein wrong?

Dark energy camera takes hyper-detailed images of nearby dwarf galaxies

By Kasandra Brabaw published

New, stunningly detailed images of the Large and Small Magellanic Clouds have the potential to revolutionize our understanding of the stars making up these two dwarf galaxies.

This graphic shows a map of the universe's expansion rates in different directions, estimated in a new study by Konstantinos Migkas and collaborators. The map is in galactic coordinates, with the center looking toward the center of our galaxy. The black and purple colors show the directions of the lowest expansion rates (the Hubble constant); yellow and red show the directions of the highest expansion rates.

Is there more than one dark energy?

By Paul Sutter published

What if there is more than one cosmological agent for dark energy? This mixture would have strange effects in our universe, making it potentially detectable with upcoming surveys.

Dark Energy Is Real, Despite Claim to the Contrary

By Chelsea Gohd published

Researchers claim to have found serious fault with the existence of dark energy, but not everyone is buying into it.

Each of DESI's fiber optic "eyes" can collect light from a single object, such as a part of a galaxy. The instrument then splits that light into different colors to figure out what it might be composed of and how far away that object is. This test spectrum was gathered by DESI on Oct. 22. A single fiber-optic cable (red dot) scans a region of the Triangulum galaxy and splits the light it gathers into a spectrum.

5,000 Mini-Eyes Just Blinked Open to Scan the Skies for Dark Energy

This image from NASA shows a cloud in space (Molecular Cloud Barnard 68, to be precise) that looks a bit like a void, but isn't one. Real voids don't look like much of anything from Earth... because they aren't much of anything.

New Dark Energy Data Emerges from Misshapen, Distorted, Ancient Voids

By Rafi Letzter published

There are voids in the universe, and we can't see them properly. But the good news is that astronomers just got much better at not seeing them properly.

Exotic 'Early Dark Energy' Could Be the Missing Link That Explains the Universe's Expansion

By Mara Johnson-Groh published

Measures of the universe's expansion taken from different sources don't match. An exotic form of dark energy particles could be the reason why.
