As indicated in image III below‚ the subarachnoid space is the area located between the arachnoid mater and the pia mater layers of tissue covering the brain. This anatomic space is occupied by a spongy connective tissue known as trabeculae which spans across the subarachnoid space connecting the two layers of the leptomeninges‚ providing

The Hubble Space Telescope is a space telescope that was carried into orbit by a Space Shuttle in 1990 and remains in operation. A aperture telescope in low Earth orbit‚ Hubble’s four main instruments observe in the near ultraviolet‚ visible‚ and near infrared. The telescope is named after the astronomer Edwin Hubble. Hubble’s orbit outside the distortion of Earth’s atmosphere allows it to take extremely high-resolution images with almost no background light. Hubble’s Deep Field has recorded some

citizens the relevance of space programs. A question that has been rising over the years is‚ is going into space programs worth it? Many can argue that it is a scrupulous field to join and that it’s risky. However‚ any type of job you do is treated as taking a risk.
