Using a telescope at Kitt Peak, scientists have produced the largest 3D map of the universe ever made and uncovered ...

If dark energy continues to weaken, the accelerating expansion of the universe could slow — and possibly reverse. In that ...

Scientists are homing in on the nature of a mysterious force called dark energy, and nothing short of the fate of the universe hangs in the balance.

An international team of researchers used multi-wavelength observations of active galactic nuclei to study how black holes launch relativistic jets. The sixteen sources were observed with the Event ...

The latest findings from the Dark Energy Spectroscopic Instrument (DESI) challenge long-held beliefs about dark energy. By ...

Using data from nearly 15 million galaxies and quasars, the Dark Energy Spectroscopic Instrument (DESI) has created the most detailed 3D map of the universe ever made. A new analysis combining DESI’s ...

Dark energy is a dynamic entity, rather than a matter-of-fact constant in the universe’s rapid unfurling, a team of ...

For decades, astronomers have relied on Einstein’s theory of relativity to explain the expansion of the universe, assuming ...

The fate of the universe hinges on the balance between matter and dark energy: the fundamental ingredient that drives its ...

The findings suggest that dark energy is dynamic and changes over time, and that it used to be stronger in the early stages of the universe but is weaker now. That’s particularly odd because most ...
