The APEX telescope is located on the Chajnantor Plateau in Chile at 5,100 m altitude, which is one of the few places on Earth where observations at submillimeter wavelengths are possible.
Submillimeter telescopes, like common telescopes, consist of a large collecting mirror called a primary, in this case 6 meters in diameter, and a smaller secondary mirror called a subreflector.
The telescopes contributing to this result were ALMA, APEX, the IRAM 30-meter telescope, the James Clerk Maxwell Telescope, the Large Millimeter Telescope Alfonso Serrano, the Submillimeter Array, the Submillimeter Telescope, and the South Pole Telescope.
In the past, researchers have been unable to measure small features such as the inner diameter of a submillimeter hole, but NIST has recently demonstrated the ability to measure holes as small as 700 [micro]m in diameter.
The paper, titled "The circumgalactic medium of submillimeter galaxies.
Washington, Feb 27 ( ANI ): New images from the Smithsonian's Submillimeter Array (SMA) telescope provide the most detailed view yet of stellar nurseries within the Snake nebula, offering new insights into how cosmic seeds can grow into massive stars.
Submillimeter waves are a unique diagnostic tool for the dense innermost region of the outflow, and at that exact place we detected the rotation.
Then, the key to the solution will be millimeter and submillimeter wave (*4), which can be observed with ALMA.
Also important to his narrative are his tenure as the first director of the Space Telescope Science Institute, which is responsible for the scientific utilization of the Hubble Space Telescope; his subsequent directorship of the European Southern Observatory, which constructed the Very Large Telescope operating in the Atacama Desert of Chile; and finally his involvement with the National Radio Astronomy Observatory, which is constructing the world's largest array of millimeter and submillimeter radio antennas on the Llano de Chajnantor in Chile.
In 2013, Oya and her collaborators used the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile to observe the star in submillimeter wavelengths, as that kind of light can penetrate the dust cloud -- for reference, red light is around 700 nanometers.
Since the discovery, astronomers have examined Tabby's star with both space- and ground-based telescopes, in optical, infrared, and submillimeter wavelengths.
Bally and his team earlier observed the debris - first revealed using the Submillimeter Array in Hawaii in 2009 - in near-infrared, using the Gemini South telescope, also in Chile, which showed them the streamers extend almost one light-year from end to end.
