Prominences 1. Prominences are immense clouds of glowing gases that erupt from the upper chromosphere. 2. The loops or arches of gases may shoot as high as 100 000 kilometres from the surface of the Sun. This allows some of the surface gases, mainly hydrogen and helium, to escape into space.
Cepheid variable stars have masses much larger than our Sun; the more massive stars are more luminous and have more extended envelopes 10. The stars near the centers of galaxies are orbiting at high velocities, which mean that there is the presence of super-massive black holes in the centers of most galaxies. 11. Large galaxies can absorb smaller galaxies called galactic cannibalism. Chapter 14 1.
The sun is 93 million miles away from Earth, but its gravity is strong enough to hold the Earth in its orbit. The gravity of the solar system keeps everything in the system, including comets and asteroids, orbiting the center of the system, the sun.

limb_flare_sm.jpg (5710 bytes)Solar flares are tremendous explosions on the surface of the Sun. In a matter of just a few minutes they heat material to many millions of degrees and release as much energy as a billion megatons of TNT. They occur near sunspots, usually along the dividing line (neutral line) between areas of oppositely directed magnetic fields. The biological effect. There is a growing body of evidence that changes in the geomagnetic field affect biological systems.
These industrial activities have raised atmospheric gases such as carbon dioxide which contribute to greenhouse gases. The extra amount of these gases mean there is a thicker layer, meaning the gases absorb outgoing long-wave radiation which traps in too much heat. Increasing amounts of CO₂, methane, nitrous oxide, water vapour and ozone all contribute to this. The main cause in this rise is the burning of fossil fuels such as coal, oil, natural gas and petrol. Since the industrial revolution the levels of atmospheric CO₂ have increased from 280 parts per million to 380ppm for the past 10,000.
184). One interesting contribution of the comet is the solar effect. The process starts by a comet approaching the sun. Once the comet approaches the sun, solar heat sublimates, or evaporates, the ices. This causes the comet to brighten enormously.
Being that they were in space there is no air in the moon’s atmosphere thus a flag waving is impossible. 2. Multiple light sources. When on the moon the sun is the only light source therefore all shadows should run parallel to one another. This was not the case, in various videos and pictures from the landing, shadows are clearly seen in many different directions.
There may be a small core of rock and perhaps ice at the center. This is surrounded by an ocean of liquid hydrogen and helium in the form of a metal. Above this is a layer of liquid hydrogen and helium, and above this a thick atmosphere. Jupiter is radiating energy, possibly as a result of radioactivity. The most famous feature is the Great Red Spot, which may be a huge storm in the atmosphere.
That’s right, solar flares. The sun has small explosions on its surface, called hotspots that go off every so often. Scientists analyze and observe these hotspots, and some say that a super explosion is due up. That’s not all however. The earth is also overdue.
