Several ways have been proposed to examine dark energy, in hopes of finding out just what it is. One of them, “supernovae” for short, certainly works: it’s how dark energy was discovered in the first place.

NASA and the U.S. Department of Energy (DOE) have signed a memorandum of understanding for the implementation of the Joint Dark Energy Mission, or JDEM.

NASA and the U.S. Department of Energy should pursue the Joint Dark Energy Mission (JDEM) as the first mission in the "Beyond Einstein" program, according to a new report from the National Research Council. Beyond Einstein is NASA's research roadmap for five proposed mission areas to study the most compelling questions at the intersection of physics and astronomy.

NASA has created a new office to study in more detail some of the universe's most exotic phenomena: dark energy, black holes and cosmic microwave background radiation.

The U.S. space agency has created a new office to study more closely cosmic phenomena such as dark energy and black holes.
