Earth’s Speed and Rotations

Posted on:

Earth's Rotation Earth's rotation creates the daily cycle of day and night, with the equator spinning at around 1,037 miles per hour. This defines a standard 24-hour day, though we don't feel this motion in our daily lives. The equator moves faster than higher latitudes due to Earth's larger circumference […]

Earth’s Spin and Gravity

Posted on:

Earth's Rotation and Gravity The Earth's spin creates a bulge at the equator, turning our planet into an oblate spheroid. As a result, gravitational force dips slightly at the equator and peaks at the poles. This bulge stems from centrifugal forces due to Earth's rotation, spreading the mass outwards and […]

JWST Observation Methods

Posted on:

JWST's Location and Orbit The James Webb Space Telescope (JWST) occupies the L2 point, approximately 1.5 million kilometers from Earth. This location keeps the Sun, Earth, and Moon aligned, ensuring the telescope always faces away from these infrared sources. This positioning reduces thermal interference and maintains JWST's temperature at around […]

Galaxy Size Analysis

Posted on:

Galaxy Size Distribution The Sloan Digital Sky Survey (SDSS) has revealed approximately 140,000 galaxies in various shapes and sizes. Late-type galaxies, such as spirals, have a characteristic brightness of M_r,0 ≈ -20.5, corresponding to a stellar mass of about 1010.6 solar masses. Less massive galaxies exhibit greater brightness variability (about […]
