How deep is the Tycho crater? What is the most dense planet in the galaxy? How abundant is hydrogen in the Earth's crust, the ocean, and the atmosphere? How strong is Jupiter's magnetic field? What is the strength of the gravitational field 1.27 x 10^7 m above the Earth's surface?
A planetesimal is small bodies from which a planet originated in the early stages of formation of the solar system. Protoplanets are whenplanetesimals join together through collisions and through the force of gravity to form larger bodies. Because they have their gases they are not as dense as ...
The Interior of Planet Mars Mars, like Earth, has a dense inner core. Thought to measure 930 to 1,300 miles (1,500 to 2,100 kilometers) around its radius, this layer contains nickel, sulfur and iron. The core is enveloped by a series of other layers, with the outermost being the...
Astronomers can tell that it lacks a dense core from the details of its gravitational pull on the Galileo spacecraft during several very close flybys. This fact surprised scientists, who expected that all the big icy moons would be differentiated. [#highlight3]It is much easier for an icy...
Ice is less dense than water because water molecules form crystalline structures at freezing (32 degrees Fahrenheit or 0 degrees Celsius) temperatures. The thermal properties of water are also linked to its hydrogen bonds. Water has a very high specific heat capacity, which is the amount of ...
A rather expensive book that is dense and scholarly, I was nevertheless very impressed with it. Naturally, the first question is whether Jungle rehashes that book for a general audience. It does, but only to an extent. Next to being far more outspoken, Roberts has also decided to make ...
In this guide, you will learn easy ways anyone can get started in birding watching or become a birder, even if they are a total beginner!
If strange matter, which is incredibly dense and stable, were to encounter a black hole, theoretical predictions suggest it might be absorbed. The interaction's specifics, such as whether strange matter could alter the black hole's properties, remain a topic of speculation among physicists. Can...
Uganda’s Bwindi Impenetrable Forest is a sanctuary for mountain gorillas, hosting nearly half of the world’s remaining population. Trek through the dense forest to meet these gentle giants and playful chimpanzees. These primates are part of a more extensive network across Africa, providing insights...
When you strike a match here on Earth, gravity pulls cool, dense air downwards as hot gasses rise up — resulting in a teardrop-shaped flame. But on the ISS, flames take the form of tiny bluish spheres. These have already revolutionized our understanding of the combustion process. Down ...
