Because its density is so high, neutrons spin in the same way that electrons do so must obey the Pauli Exclusion Principle. 6. A pulsar does not pulse, it emits beams of radiation that sweep around the sky as the neutron star rotates, and astronomers detect pulses when they sweep over the Earth. 11. Sometimes in binary systems, mass flows into a hot accretion disk around the neutron star and causes the emission of x rays.
Introduction One look at the surface of the Moon should convince you that "empty space" is not so empty after all. There is actually a wide range of objects floating between the planets, from tiny particles to asteroids that can be a hundred miles across, debris left behind when the planets were formed. These objects can be perturbed from their orbits (by a close passage by a planet, a passing star, any number of things) and onto paths that cross ours -- or any other planet or moon. When
One example of history that is retained on the surface of the Moon but has been lost from the surfaces of the terrestrial planets is the simple impact craters. They are very common and very easily spotted on the moon. The simple impact is created from meteorite or comet crashing into the surface of the moon. At the moment of collision, the surface of the moon ejects debris out into space and leave a crater behind. A simple impact crater has a circular shape surrounded by a rim that is elevated from the center of the crater.
Said O'Keefe: If tektites are terrestrial, it means that some process exists by which soil or common rocks can be converted in an instant into homogeneous, water-free, bubble-free glass and be propelled thousands of miles above the atmosphere. If tektites come from the Moon, it seems to follow that there is at least one
Because of the plates, the Earth’s crust is in continuous motion, but without plate tectonics to dissipate the heat in the core, Venus undergoes a different process where the mantle will heat up to the point where the crust is weakened. The planet then goes through a period of subduction over approximately 100 million years where the entire surface is recycled. This means that the surface of Venus is much older than Earth’s surface, and this in turn supports a much higher number of volcanoes, which have shaped much of the surface. Venus also has considerably less erosion from wind compared with earth so many of the volcanoes are in great condition. There is compelling evidence for past and present water on Mars.
(2 points) Mars. B) Cosmic Origin of the Element CLUE: The substance collected has properties indicating that it contains a few different elements. The elements in your sample were formed in a supernova and released into space when the star exploded. Small stars and cosmic rays are not hot enough to form them. Look at the chart below to see which elements are typically formed in supernova and which ones are not.

Cesium and francium are the most reactive elements in this group. Alkali metals can explode if they are exposed to
Astronauts usually have a career in either piloting or being a scientist. Some astronauts are geologists and study the rock formations on the moon. astronomers are sometimes also astronauts. Astrologers and astronomers seek understanding of how the universe works. There are several different types of biologists.
