Astronomers have analyzed the data from long-term radio observations of a binary pulsar known as PSR J1906+0746. Results of the new study, published February 5 on the arXiv pre-print server, deliver ...

Intriguingly, the observations fit with an alternative theory of gravity that could negate the need for dark matter. Although it’s since been superseded by Einstein’s theory of general relativity, ...

Lunar-based measurements reveal Earth’s outgoing radiation is dominated by low-order spherical harmonics, providing unified global data for climate and environmental studies ...

Head-scratching observations of distant galaxies are challenging cosmologists’ dominant ideas about the universe, potentially leading to the implication that the strange substance called dark matter ...

The study of climate change has been based strongly on data collected from instruments, but how local people perceive such changes remains poorly quantified. We conducted a meta-analysis of climatic ...
