The ALMA radio telescope captured the highest resolution image of the star


The Atacama Large Millimeter/submillimeter Array (ALMA) is a renowned observatory located on the Chajnantor Plateau in the Atacama Desert in northern Chile. It is the world’s largest millimeter-wave telescope, consisting of 66 receivers, which was used in the past, among others, for observing the Sun. A radio telescope was used to capture a very detailed image of the star.

Scientists pushed the ALMA radio telescope to its limits and this observatory succeeded capture the highest resolution image ever research facility. The photo was captured the star R Leporiswhich is located in the Milky Way.

The star R Leporis is located in our galaxy and is from us approximately 1,350 light-years away. The ALMA radio telescope was specially prepared to capture this image. A band 10 receiver with the highest frequency and a configuration covering an area of ​​10 miles (approx. 16 km) was used. As a result, we managed to obtain the above image of a star that is in the final phase of evolution. Orange shows emission from the star’s surface. While the surrounding gas structure is shown in blue.

Scientists believe this is it a breakthrough achievement that opens new possibilities for astrophysics. This became possible by using a new calibration technique. This allowed us to obtain an image with a resolution that was compared to the possibilities seeing a bus on the lunar surface from Earth.


The new image opens up further possibilities for future observations. Scientists are already excited and say the new technique will enable wider use of the ALMA radio telescope. “The success of high-resolution observations at band 10 demonstrates our commitment to innovation and strengthens ALMA’s position as a leader in astronomical discovery. We are excited about the new opportunities for the scientific community.” – Asaki sums up in a statement.
