Data collected by the Dark Energy Spectroscopic Instrument (Desi) at Kitt Peak National Observatory in Arizona, US, suggests ...

The most mysterious of these are ultra-high-energy cosmic rays (UHECRs), which exceed 10¹⁸ electron volts (eV) in energy. These particles: ・Travel at nearly the speed of light ...

Harvard astronomer Avi Loeb discusses how scientists trace the cosmic journey of high-energy neutrinos from the Big Bang to ...

Our current best theories of the universe suggest that dark energy is making it expand faster and faster, but new observations from the Dark Energy Spectroscopic Instrument suggest this mysterious for ...

But the results of DESI’s latest analysis imply that the cosmic expansion is accelerating less now than it was in the past, which does not fit the assumption that dark energy is a cosmological ...

Measurements of the faint afterglow of the Big Bang (known as the cosmic microwave background) are also important. They do not directly measure dark energy or how it evolves, but they provide clue ...

This phenomenon, known as cosmic shear, can provide clues about the role of dark energy in shaping the universe. With this model, they transformed simulated shear data from specific points into ...
