The UP NISMED Observatory
The observatory houses one of the country’s most powerful and most modern telescopes. Its main telescope is a 40 cm (16 in) reflecting telescope, equipped with accessories such as a 20 cm (8 in) refractor guidescope, an 8 × 50 finderscope, and a fully-automated motor-driven mount.
Stargazing sessions are conducted at the UP NISMED Observatory from January to March each year as part of UP NISMED’s mandate to serve as the national center for the improvement and reform of science and mathematics education at the basic and teacher education levels.
One of the highlights of the stargazing sessions is the viewing of night-sky objects through one of the country’s largest telescopes. Students as well as their teachers marvel at the numerous craters of the Moon, the gas giant Jupiter and four of its brightest moons, Saturn with its beautiful ring system, Mars and its polar ice caps, and the constantly changing phases of Venus.
Participants also listen to various K to 12 Earth and Space Science lectures on the solar system, constellations, comets, and many others. The observatory primarily entertains requests made by schools and other educational institutions. Sessions are conducted at the roof-deck of the NISMED Science Teacher Training Center (STTC) where guests become astronomers for a night.
