View of our Milky Way galaxy Featured 1994 Image

View of our Milky Way galaxy

The Milky Way. Map of the central region of our galaxy, seen from a tilted angle. The Milky Way is a spiral galaxy with a short bar (yellow-white) at centre and a diameter of about 100, 000 light years. It contains about 15 billion stars. Molec- ular clouds (orange) and bright nebulae (purple) populate the galaxy's spiral arms. Molecular clouds consist of molecules and dust, and are associated with regions of star formation. Nebulae are formed by hydrogen lit up and ionised by nearby young, hot stars. Clouds of neutral hydrogen are in yellow. Based on locations of 1500 stars, nebulae and other objects, the Henbest/Baum map of the galaxy was published in 1994

Coloured SEM of mitochondria in ovarian cells Featured 1994 Image

Coloured SEM of mitochondria in ovarian cells

Mitochondria. Coloured Scanning Electron Micro- graph (SEM) of mitochondria and smooth endoplasmic reticulum in an ovarian granulosa- lutein cell. The cell occurs in the corpus luteum of the ovary, which develops after ovulation and secretes the hormone progesterone. Mitochondria (pink) are seen sectioned, containing tubular cristae. Active secretory cells have many mitochondria which play a role in cell respiration. Membranes of smooth endoplasmic reticulum (ER, yellow) are also seen; commonly found in secretory cells, ER synthesizes lipids and transports substances around the cell.
