For astronomers, the challenge of mapping the Universe has been similar to mapping a city from night-time aerial snapshots showing only streetlights. These pick out a few interesting neighbourhoods, ...

It has been over two decades since the discovery of dark energy. Scientists have therefore had more than 20 years to decode the secrets of this invisible substance that appears to be pulling the ...

Why it matters: Researchers at Berkeley Lab have created the largest 3D map of the universe, with a precision of 1 percent. But what they discovered is startling in its implications and raises ...

Scientists have proposed new instruments that would use spectroscopy to decode dark matter, dark energy and cosmic inflation. Telescope images can tell us a whole lot about celestial objects: where ...

Starting late last decade, the Mayall 4-meter telescope at Kitt Peak National Observatory in Arizona began running something called the Dark Energy Spectroscopic Instrument. DESI for short, it is ...

Astronomers have mapped the universe's quasars in unprecedented detail thanks to a ream of accidental observations from the Gaia observatory. The new "3D catalog" is expected to offer researchers ...
