What is outer space made of? What are planetary nebula made of? What is Mercury's surface made of? What is Ceres named after? What is Pluto made of? What caused Jovian planets and terrestrial planets to form differently? Which of the Solar System's gas planets have storms?
What are planets outside of the asteroid belt made of? What holds the asteroid belt in place? What is the diameter of the asteroid belt? What is the atmospheric composition of the asteroid belt? What are the biggest asteroids in the inner asteroid belt?
we have already succeeded in using satellites for communications, weather forecast and oil exploration and with further space research, more problems we are having now can be solved. for instance, with the success of space shuttles and the feasibility of living in other planets, we may solve ...
So molecules like this ended up on Earth. In fact, what we call meteorites are pieces broken away from comets and asteroids that came in our atmosphere and left their extra-terrestrial organic matter on the surface of primitive Earth.这样的分子最终来到了地球上。事实上，我们所说的陨石是来自彗星...
Globular clusters are dense, symmetrical regions of stars. They typically reside in the extended stellar halos, or outer regions, of their home galaxies. They can be composed of a few thousand stars or up to tens of millions of stars. Globular clusters house some of the oldest stars in ...
Comets are known to be remnants of the early solar system but their numbers are very uncertain. Each year several dozen new comets are discovered. Most asteroids orbit the Sun in nearly circular paths lying between Mars and Jupiter. Comets originate in the outer fringes of the solar system, ...
We’ve got the asteroid belt, which contains about 90 percent of all asteroids orbiting the Sun.These asteroids are uh, like the terrestrial planets, in that they're composed mostly of rocky material and metals.Far from the sun...in the outer solar system, beyond Jupiters 'orbit...temperat...
The clouds observed in the atmosphere are made up of frozen CO2. The atmospheric composition on Mars is: Carbon dioxide: 95%. Nitrogen: 3%. Methane: 30 ppb by volume. Oxygen and water: trace amounts. Argon: 1.6%. Who Discovered Mars? With Mars being one of the five planets visible to...
There are three known types of neutrinos; a fourth, the sterile neutrino, is proposed as a dark matter candidate. The sterile neutrino would only interact with regular matter throughgravity. "One of the outstanding questions is whether there is a pattern to the fractions that go into each neut...
They´re made up of ice and dust grains that are too small to survive passing through the atmosphere. And, uh, meteor showers happen at regular intervals every year because they´re debris left over from periodic comets.M: Excuse me, Professor Morgan, you just said meteor showers are ...
