How Gemini Observatory connects across Asteria Star — scientific, cultural, and astrological links are kept separate.
The nearest large spiral galaxy to the Milky Way and the most distant object readily visible to the naked eye.
NSF's NOIRLab is the US national centre for ground-based, night-time optical and infrared astronomy, operating Gemini, CTIO, Kitt Peak, and the Rubin Observatory.
Visible light is the band the human eye sees and the traditional domain of optical telescopes.
Infrared light penetrates dust and reveals cool objects — forming stars, planets, and distant galaxies.
Gemini North is an 8.1-metre telescope on Mauna Kea, one of the twin Gemini telescopes covering the whole sky.
Gemini South is the 8.1-metre southern Gemini telescope, located on Cerro Pachón in Chile.

ALMA is an international radio observatory of millimeter and submillimeter antennas located on the Chajnantor plateau in the Atacama Desert of northern Chile.
Arecibo Observatory in Puerto Rico operated a 305-metre radio dish — for decades the largest single-dish radio telescope — until its collapse in 2020.
Cerro Tololo Inter-American Observatory in Chile is a NOIRLab site whose telescopes carried out the Dark Energy Survey.
The next-generation ground-based observatory for very-high-energy gamma rays, an array of imaging atmospheric Cherenkov telescopes being built across two sites — one in the northern hemisphere on La Palma and one in the southern hemisphere in Chile — to catch the faint blue flashes that gamma rays make in the atmosphere. The largest such observatory ever built.
A proposed United States third-generation gravitational-wave observatory with arms up to forty kilometres long — a scaled-up successor to LIGO that, with the Einstein Telescope, would open the distant gravitational-wave universe.
A proposed European third-generation gravitational-wave observatory, to be built underground in a triangle of ten-kilometre arms. Its far greater sensitivity would detect compact-binary mergers across most of the observable universe.
