by latitude and other geographic factors, the long-term average global climate is quite stable during interglacial periods,[6] and variations of a degree or two of average global temperature have historically had major effects on the ecological balance, and on the actual geography of the Earth.[...
What is the exact mass of the sun?The Solar System:The solar system consists of the Sun, the eight planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune), and a large number of moons belonging to these planets, as well as other bodies like asteroids and ...
Types of Telescopes A telescope's optical tube has two important parameters: "aperture" and "optical quality". Aperture is the diameter of the objective lens or a mirror - it defines how much light the telescope gathers and its maximum resolving power. Optical quality is a general therm whic...
Of all the mass contained within the solar system,NASA saysthat 99.8% of it is locked up in the sun. Around 4.6 billion years ago a disk of gas and dust collapsed to birth our star and what material didn't go into the sun was leftover as a planetarynebulafrom which the planets emerg...
the amount of detail that it revealed was just way too much that would mean the sketch would take a ridiculous amount of time to complete. The 4" gave me what I felt was the best balance between FOV and amount of detail on show. Don't forget, the LMC is some 12° in diameter, ...
Angular size is measured using a combination of distance and actual size of the object. This allows astronomers to determine if an object is moving towards the Earth, away, or remaining stationary.Answer and Explanation: Angular size is the degree to which a camera, telescope or other ...
‒ What is it? Angles and linear dimensions are measured by the small-angle equation. This equation involves the angular size of an object, its linear size, and its distance. ‒ My comment? What does it mean to me? a = angular size, expressed in seconds of arc. d = diameter of ...
So, naturally, I woke up very early and took a trip down to my nearby observing site. I wasn’t sure I’d be able to see everything from my yard, and the pre-dawn sky is pretty damn interesting right now. You have a crescent moon, Orion, Venus, Jupiter and abunch of other cool...
If e=0, the orbit is a circle. Venus, the planet of peace and harmony, has the least eccentric, most circular orbit of any of these bodies. Pluto, ruling death and transformation, is the most eccentric of the planets, but there are many bodies with even greater eccentricity. Could ...
Question 1 (Periodic tiling question) Let be a finite subset of . If there is a solution to the tiling equation , must there exist a periodic solution to the same equation ? We know that the answer to this question is positive for finite groups (trivially, since all sets are periodic ...
