Astronomers Make Highest-Resolution Observations Ever from Earth
The Event Horizon Telescope (EHT) Collaboration has conducted test observations with the highest resolution ever obtained from the surface of the Earth. This feat was achieved by detecting light from distant galaxies at a frequency of around 345 GHz, equivalent to a wavelength of 0.87 mm. The Collaboration estimates that, in the future, they will be able to make black hole images 50% more detailed than before. This improvement will sharpen images of supermassive black holes, and allow astronomers to image more black holes than ever before.
Astronomers, Satellite Internet Provider Develop New System to Share the Sky
New cooperative work between the U.S. National Science Foundation National Radio Astronomy Observatory (NSF NRAO) and SpaceX shows a way to share the radio spectrum between radio astronomers and industry.
Plasma Bubbles and the “Engine” of Fast Radio Bursts
An international team of astronomers has demonstrated that persistent radiation in some fast radio bursts originates from a plasma bubble, shedding new light on the enigmatic sources powering these cosmic phenomena.
