Investigation of dark matter. De la Vega believes that astronomers will need to alter their theoretical models for how galaxies form and evolve by accounting for the amount of dark matter included ...
Astronomers used NASA's James Webb Space Telescope to reveal 44 stars in a galaxy so far away, its light dates to when the universe was half its age. In 'groundbreaking' study, astronomers detect ...
The Webb telescope's historic discovery will allow astronomers going forward to investigate "one of the universe's greatest mysteries — dark matter," according to the Center for Astrophysics.
In astronomy, dark matter is a hypothetical form of matter that does not interact with light or other electromagnetic radiation.Dark matter is implied by gravitational effects which cannot be explained by general relativity unless more matter is present than can be observed.
A MAssive Compact Halo Object (MACHO) is a kind of astronomical body that might explain the apparent presence of dark matter in galactic halos. A MACHO is a body that emits little or no radiation and drifts through interstellar space unassociated with any planetary system (and may or may not be composed of normal baryonic matter). Since MACHOs ...
Searches for the products of dark matter interactions are profitable because there is an extensive amount of dark matter present in the universe, and presumably, a lot of dark matter interactions and products of those interactions (which are the focus of indirect detection searches); and many currently operational telescopes can be used to ...
“Dark matter seems to be ubiquitous throughout the universe, but how exactly has it been clumping or clustering over time remains difficult to quantify for large swathes of the night sky,” he ...
In an approach known as multi-messenger astronomy, gravitational wave data is combined with data from other wavelengths to get a more complete picture of astrophysical phenomena. Gravitational wave astronomy helps understand the early universe, test theories of gravity, and reveal the distribution of dark matter and dark energy.
