Astronomers conducted successful observations of the edge of the Moon, followed by the first successful interferometry test observations using two Band 1 receivers on August 17, and acquisition of the ...

Scientists have successfully fabricated corrugated all-metal 3D-printed horns for the ALMA Band 1 receivers (Radio Frequency: 35-50 GHz). The NAOJ ALMA Project and Advanced Technology Center have ...

The National Science Foundation (NSF) and the board of the Atacama Large Millimeter/submillimeter Array (ALMA) have approved a multi-million dollar upgrade project for the Observatory’s 1.3mm (Band 6) ...

Researchers have used the latest wireless technology to develop a new radio receiver for astronomy. The receiver is capable of capturing radio waves at frequencies over a range several times wider ...

Solar eclipses can have a noticeable impact on the structure and dynamics of Earth's upper atmosphere—the ionosphere. This is primarily due to the sudden reduction in solar radiation reaching the ...

Radio astronomy has changed how we view the universe, with radio telescopes allowing the retrieval of information beyond visible light by observing radio waves emitted from various astronomical ...

Visible light is just one part of the electromagnetic spectrum that astronomers use to study the Universe. The James Webb Space Telescope was built to see infrared light, other space telescopes ...

The NAOJ ALMA Project and Advanced Technology Center have successfully fabricated corrugated all-metal 3D-printed horns for the ALMA Band 1 receivers (Radio Frequency: 35-50 GHz). Since around 2015, ...

A new set of receivers installed on antennas at the Atacama Large Millimeter/submillimeter Array (ALMA) have achieved first light. With it, they set a new record for the longest wavelengths visible ...
