While it's relatively straightforward to identify the shapes of planets, moons and galaxies, it's more complex to measure the shape of the universe. In fact, this question has a very counterintuitive answer, because when we think of the shape of something, we might imagine an object seen fr...
Dwarf galaxies are small galaxies that contain somewhere between 100 million to a few billion stars. This size is much smaller than a standard galaxy such as our Milky Way that contains somewhere between 250 billion and 400 billion stars. Dwarf galaxies can appear in the same 3 basic shapes ...
The combination of the two disturbances (i.e. the two “virtual particles”) remains a particle with the energy, momentum and mass of the incoming electron. Now there are many other types of disturbances that fields can exhibit that are not particles. Another example, and scientifically on...
See a panorama of the moon with Venus and Saturn on May 24.(Image credit: Starry Night) If you want to catch a very slim-waning crescent moon — just 11%-illuminated — this is the morning to see it. Best seen about 45 minutes beforesunrise where you are, the moon will be to the...
Perhaps the drawing of a shape on the balloon might appear to the ant as the presence of dark mater. A lot of such shapes might leave the (clever) ant thinking that it actually inhabited less than 5% of its 'universe'. I have just obtained a copy of FLATLAND by Edwin A Abbott, litt...
Earth (or, "the earth") is the only planet presently known to support life, and its natural features are the subject of many fields of scientific research. Within the solar system, it is third nearest to the sun; it is the largest terrestrial planet and the fifth largest overall. Its mo...
Surrounding the galaxy for thousand and thousand of light years is space.At great distances,however,billions of other galaxies are scattered.These galaxies are of many shapes and sizes.The Milky Way Galaxy is shaped like a spiral(螺旋型)disk.Other galaxies have been found to be shaped like ...
I woke up a little while back (3am) to catch a glimpse of Jupiter and its moons. (I may sound a little desperate and maybe I am but the next 7 days are going to be full of rain and clouds.) Jupiter just started to rise above the Shibuya city center. Here I was up in the ...
Name the three basic types of rocks, and briefly state the process by which each type is formed. What were the practical values offered by astronomy to ancient civilizations? Explain tidal waves. What makes them, and how are they related to different phases of the moo...
