Galaxy cluster Abell 1060 Featured 25 Jul 2003 Print

Galaxy cluster Abell 1060

Galaxy cluster Abell 1060. Infrared composite image of the galaxy cluster Abell 1060, also called the Hydra cluster. More than 100 galaxies are clustered toward the southern constellation Hydra. Most of the stars in these galaxies are cool, old stars. The two very bright stars are in our own galaxy, the Milky Way. Infrared can peer through the dense dust that obscures millions of stars from sight at visible wavelengths. These images were made as part of the Two Micron All Sky Survey (2MASS) project using ground based telescopes in the USA and in Chile. The project began in 1997 with the aim of surveying the entire sky with near-infrared

Artwork of osteoporosis: osteoclast cell eats bone

Process of osteoporosis. Illustration of an osteo- clast bone cell in action during removal of bone tissue. An osteoclast (blue, centre) is a giant multi-nucleated cell that normally breaks down the calcified matrix of bone (yellow) during bone growth and formation. In the disease of osteo- porosis, however, more of these cells form. Cells which would normally become osteoblast bone growth cells (pink) coalesce to produce osteoclasts. As a result, bones become brittle and less dense, with a greater risk of fractures. Osteoporosis is most common in post-menopausal women, attributed to a decline in ovarian hormone which helps maintain bone mass. Steroid treatment is effective
