Why is Titan’s atmosphere orange?
Space and AstronomyThe orange color is due to the hydrocarbon particles which make up Titan’s atmospheric haze. The second, monochrome view shows what Titan looks like at 938 nanometers, a near-infrared wavelength that allows Cassini to see through the hazy atmosphere and down to the surface. Why does Titan have an orange haze? The surface of Titan

Are alternate exterior angles congruent?
Space and AstronomyThey are located “outside” the two parallel lines but on opposite sides of the transversal, creating two pairs (four total angles) of alternate exterior angles. Alternate exterior angles are congruent, meaning they have equal measure. Are alternate exterior angles are always congruent? Alternate exterior angles are always congruent. If alternate exterior angles are congruent then

Who proposed the capture theory of the moon?
Space and AstronomyThomas Jefferson JacksonThomas Jefferson Jackson See in 1909. In this model, the Moon evolved elsewhere in the Solar System, before being captured into a close orbit around Earth. Who proposed the capture theory? Michael Mark Woolfson The capture hypothesis, proposed by Michael Mark Woolfson in 1964, posits that the Solar System formed from tidal interactions

Why is Spica so bright?
Space and AstronomyWhy is Spica brighter than the sun? The light from Spica’s two stars, taken together, is on average more than 2,200 times brighter than our sun’s light. Their diameters are estimated to be 7.8 and 4 times our sun’s diameter. Spica is one of several bright stars that the moon can occult (eclipse). Is Spica

What are the properties of parallelograms?
Space and AstronomyThere are six important properties of parallelograms to know: Opposite sides are congruent (AB = DC). Opposite angels are congruent (D = B). Consecutive angles are supplementary (A + D = 180°). If one angle is right, then all angles are right. The diagonals of a parallelogram bisect each other. What are the 7 properties

How do Saturn’s moons affect the Rings?
Space and AstronomyCassini watched some of Saturn’s moons steal ring particles, and other moons contribute particles to the rings. Cassini found that much of the material for Saturn’s E-ring—a diffuse ring outside the bright, main rings—comes from the moon Enceladus, which is venting icy particles and gas into space as it orbits Saturn. How do Saturn’s moons

What is the complement of probability?
Space and AstronomyThe complement of an event is the event not occuring. The probability that Event A will notoccur is denoted by P(A’). The probability that Events A and B both occur is the probability of the intersection of A and B. The probability of the intersection of Events A and B is denoted by P(A ∩

What does the nebular theory predict?
Space and AstronomyThe nebular theory predicted the existence of the Kuiper belt 40 years before it was discovered! There were many more leftover planetesimals than we see today. Most of them collided with the newly-formed planets & moons during the first few 108 years of the Solar System. We call this the heavy bombardment period. What does
