Central Molecular Zone
The Central Molecular Zone or CMZ is a region of the Milky Way Galaxy rich in an estimated 60 million solar masses () of gas within a complex of giant molecular clouds. It spans the centre of the Milky Way, and as such is in the Sagittarius constellation, between galactic longitude 1.7° and -0.7°, and latitudes -0.2° and +0.2°. The CMZ differs considerably from other large volumes of the Milky Way in terms of gas density, temperature, and turbulence. Its molecular gas density is several orders of magnitude greater than the galactic disk. Its gas temperature typically ranges from 50 to 100 kelvin but, particularly near the Galactic Center, can be as high as 400 to 600 K. Sampling of spectral line widths within the CMZ are in the 15 to 50 km/s range, compared to 1 to 10 km/s for giant molecular clouds in the galactic disk. Additionally, compared to the galactic disk, the CMZ produces a higher flux of cosmic rays and also emits copious ultraviolet and X-ray radiation. The ...

Cheyenne Mountain Zoo
The Cheyenne Mountain Zoo is a zoological park A zoo (short for zoological garden; also called an animal park or menagerie) is a facility where animals are kept within enclosures for public exhibition and often bred for conservation purposes. The term ''zoological garden'' refers to zoology, ... located southwest of downtown Colorado Springs, Colorado, on Cheyenne Mountain in the United States. At an elevation of above sea level, it is the highest zoo in the country. The zoo covers , 40 of which are in use. The zoo houses more than 750 animals, representing nearly 170 different species, with more than 30 endangered species. The zoo was ranked the #2 best zoo in North America in 2025 by ''USA Today''. It is accredited by the Association of Zoos and Aquariums. History Businessman Spencer Penrose was given a gift of a bear in 1916 which inspired him to collect animals. Animals were housed at Penrose's The Broadmoor, Broadmoor Hotel until a monkey bit a hotel guest. Cheyenne Mou ...
