A:
Outer space contains a low density of particles, primarily hydrogen gas, along with electromagnetic radiation. Many people, however, mistakenly believe outer space is a complete vacuum. The term "outer space" is used mainly to distinguish the space between planets from the planets and their airspace.

Q: What is the farthest star from Earth?
A: Scientists will never know the farthest star from Earth, as the star is so far away that its light has not, nor will ever, have enough time to reach Earth. Even the stars within the visible universe are far too numerous to count, but the farthest one that humans have ever detected is about 55 million light years away. This incredibly distant star is called SDSS J 122952.66 +112227.8. -
Q: What is the purpose of the Hubble space telescope?
A: The Hubble Space Telescope was created to capture detailed images or objects that are too far away to be viewed with conventional telescopes. The Hubble's instruments create images that are far superior to those of terrestrial observatories, which suffer from the effects of atmospheric distortion. -
Q: What does the full moon symbolize?
A: The full moon is said to symbolize different things in various cultures, including the control of water as well as the rhythm of time. The phases of the moon are also used to represent phases of life. -
Q: What color is the Milky Way?
A: In 2012, a team of astronomers from the University of Pittsburgh announced that the Milky Way galaxy is aptly named thanks to its pure, milky white color, which the scientists described as resembling a fresh snowfall. The fact that Earth is located within the Milky Way galaxy has made the process of measuring the galaxy's color difficult; obstructions from things like dust and gas within the galaxy had previously made it hard for scientists to get a broad enough view of the Milky Way in order to determine its color. -
Q: What is Jupiter's atmosphere made up of?
A: The atmosphere of Jupiter consists of 90 percent hydrogen gas and nearly 10 percent helium. However, its atmosphere has trace amounts of ammonia, sulfur and water vapor. Jupiter is a gas giant that is also the biggest planet in the solar system. -
Q: Where on the celestial sphere can you look for the planets?
A: The sun and planets follow the ecliptic, an imaginary plane in the celestial sphere tilted approximately 23.5 degrees relative to the celestial equator. Earthbound observers see the sun and planets move along the ecliptic arc, rising up from the east and setting in the west. - See More Astronomy Questions

Q: Where can I find a list of omnivorous animals?
A: The website for the St. John Fisher College has a webpage dedicated to lists of omnivores and omnivore food sources. Omnivores are animals that consume both plants and animals. -
Q: What is the function of the midbrain?
A: The function of the midbrain, or mesencephalon, is to control an individual's hearing, motor control, vision, arousal and temperature regulation. In addition, the midbrain also controls a person's sleep and awake cycle. -
Q: Why is it important to classify organisms?
A: There are many reasons that classifying organisms is important, such as helping understand the genetic relationships between different groups and species, helping with wide studies of organisms and helping to develop new biological sciences such as biogeography. Each of the groups and sets are created by studying the differences and similarities found in species and organisms known. -
Q: What are some characteristics of a Volvox?
A: Characteristics of a Volvox include the fact that each cell contains two flagella, which aids in movement through water, and the colonies reproduce asexually. The cells of a Volvox are held together by protoplasm strands. -
Q: Why is it important for scientists to classify organisms?
A: When scientists classify organisms, they are grouping organisms together so they can have a way to study them in a more efficient manner. Since there are millions of organisms on the Earth, it’s much easier to group them together for better research methods. -
Q: What is natural vegetation?
A: Natural vegetation refers to the plants and other flora that make up the plant life in the region. The natural vegetation will determine the characteristics of the area. - See More Biology Questions

Q: What happens when you put celery in saltwater?
A: When celery is placed in salt water, the portion of the celery stalk placed in the salt water becomes soft, limp and mushy. The celery loses its firmness. -
Q: Why do some objects sink while others float?
A: Whether an object sinks or floats depends on its density and the density of the liquid into which it is placed. If the object has a greater density than the liquid, it sinks. If it has less density, the object floats. -
Q: How do a sodium atom and a sodium ion differ?
A: The difference between a sodium atom and a sodium ion is that sodium atoms have a neutral charge, while sodium ions have a positive charge. Sodium ions are written with its symbol (Na) and a plus (+) sign. Sodium atoms are simply written with its atomic symbol. -
Q: How was the proton discovered?
A: The proton was discovered by Ernest Rutherford through the gold foil experiment, says the Purdue University College of Science. The results of the experiment led Rutherford to conclude that the positive charge and the mass of an atom are concentrated in a tiny fraction of the overall volume. In 1920, Rutherford proposed that the positively charged particle in an atom’s nucleus be called a proton. -
Q: How is cooking related to chemistry?
A: Cooking is related to chemistry because the preparation of many types of foods involves chemical reactions. When cooks understand how chemical processes work during cooking, they are able to make adjustments and produce better foods. -
Q: What is silicone made of?
A: Silicone is made of a chain of alternating silicon and oxygen atoms with two other atoms or compounds bonded to each silicon atom. Its structure is somewhat similar to a hydrocarbon chain, in part because of silicon being part of the same periodic group. However, bonds between silicon atoms, unlike bonds between carbon atoms, are unstable. Silicone, on the other hand, is very stable and resists both heat and chemicals. - See More Chemistry Questions

Q: Do red and yellow make you hungry?
A: Red and yellow do make people hungry, according to research results. People eat more when they are surrounded by warm colors, such as yellow, orange and red. Cold colors, such as blue, purple and black, suppress the appetite. -
Q: What is the complementary color for gray?
A: Gray is considered neutral and is complementary with any other color. Gray functions in a way that is similar to black and white when it comes to complementing other colors. -
Q: What colors when mixed together make purple?
A: Red and blue mixed together make purple. Red and blue are usually mixed in equal parts, but more red or blue are added for preference. Adding white to this mixture creates a lighter tint of purple, while adding black creates a darker shade of purple. -
Q: What color is the hottest flame?
A: The hottest flame is violet on the color spectrum and white in the visible spectrum. The type of fuel and impurities, in addition to the flame temperature, contribute to the color of the flame. -
Q: What color do you get when mixing yellow and purple?
A: Yellow and purple combine to make a neutral shade of gray. Yellow and purple are complementary colors, and complementary colors combine to form neutral shades of gray or brown, depending on the amounts of each color used. -
Q: What color does green and orange make?
A: Green and orange make brown. Per Color Matters, green and orange are both secondary colors, meaning that they are made by mixing two primary colors. Mixing any two secondary colors yields a brown shade, from muddy brown to olive brown. - See More Colors Questions
