127. The Planet Jupiter general features and some pictures. http://csep10.phys.utk.edu/astr161/lect/jupiter/jupiter.html

The Planet Jupiter The planet Jupiter is shown in the adjacent Hubble Space Telescope true-color image (Ref) . Jupiter is by far the largest of the planets. It is more than twice as massive as all other planets combined; if it had been only about 100 times more massive at birth (not so much by astronomical standards) it would have become a star instead of a planet. Then the Solar System might be a double star system instead of a single star with a planetary system. Jupiter has features very different from terrestrial planets. Its composition is more like that of stars, and if it has any solid surface it is hidden deep at its center: Jupiter is apparently almost entirely gas and liquid. It also has an internal energy source and enormous magnetic fields. Finally, the 4 largest moons of Jupiter (the Galilean Moons) are sufficiently interesting in their own right that they are among the most studied objects in the Solar System. We shall devote a separate section to studying their properties. Our most detailed information concerning Jupiter has come from the space probes Pioneer 10 (1973), Pioneer 11 (1974), Voyager I (March, 1979), Voyager II (July, 1979), and Galileo (1995-present). The first 4 were flyby missions; the Galileo probe was inserted into orbit around Jupiter December, 1995, and launched a probe into the atmosphere that transmitted information before being destroyed.

129. The Planet Neptune general features and some pictures. http://csep10.phys.utk.edu/astr161/lect/neptune/neptune.html

The Planet Neptune Neptune is like Uranus in many ways, but has its own unique features. Because of Pluto's highly elliptical orbit , it is currently the most distant planet from the Sun, at a separation of about 30 Astronomical Units. The full disk of Neptune in shown in the adjacent image (Ref) Neptune has been particularly challenging to study from the ground because its disk is small and badly blurred by the Earth's atmosphere at that distance. In spite of this, ground-based astronomers had learned a great deal about this planet since its position was first predicted by Adams and Leverrier in 1845. However, our most detailed information about Neptune has come from the Voyager 2 flyby in 1989. Next Back Top Home Help

The cloud indicated the comet is covered in the powdery stuff.

The moon is a cold, dry orb whose surface is studded with craters and strewn with rocks and dust (called regolith ). The moon has no atmosphere. Recent lunar missions indicate that there might be some frozen ice at the poles The same side of the moon always faces the Earth. The far side of the moon was first observed by humans in 1959 when the unmanned Soviet Luna 3 mission orbited the moon and photographed it. Neil Armstrong and Buzz Aldrin (on NASA's Apollo 11 mission, which also included Michael Collins) were the first people to walk on the moon, on July 20, 1969. If you were standing on the moon, the sky would always appear dark, even during the daytime. Also, from any spot on the moon (except on the far side of the moon where you cannot see the Earth), the Earth would always be in the same place in the sky; the phase of the Earth changes and the Earth rotates, displaying various continents.

140. Lecture 19: The Fate Of Massive Stars The origin and general characteristics of white dwarfs. High School level. http://www-astronomy.mps.ohio-state.edu/~ryden/ast162_5/notes19.html

Astronomy 162: Professor Barbara Ryden Monday, February 3 THE FATE OF MASSIVE STARS ``Do not go gentle into that good night. Rage, rage against the dying of the light.'' - Dylan Thomas Key Concepts The ultimate fate of a star depends on its initial mass. A massive star ends with a violent explosion called a supernova The matter ejected in a supernova explosion becomes a glowing supernova remnant All you need to know about the periodic table (for the purposes of this lecture): H = hydrogen (a nucleus containing 1 proton) He = helium (2 protons) C = carbon (6 protons) O = oxygen (8 protons) Fe = iron (26 protons) [``Fe'' stands for ``ferrum'', the Latin word for iron.] Hydrogen is the most abundant element in our galaxy. Helium comes in second. Carbon and oxygen are neck and neck for third place. (1) The ultimate fate of a star depends on its initial mass. M < 0.4 M sun : Too cool to fuse He to C and 0. These very low mass stars will eventually end as white dwarfs made of helium. 0.4 M sun < M < 4 M sun : Too cool to fuse C and O to heavier elements. These fairly low mass stars end as white dwarfs made of C and O.
