How the gas giants got so big.The article discusses research on the formation of the gas giants, the solar planets Jupiter and Saturn, noting models on the formation of planetesimals in relation to a solar system model discussed in the August 19, 2015 issue of the journal "Nature."...
The maximum height of trees is limited by their ability to pull water up the trunk, with tracheids playing a crucial role in water transport. The diameter of tracheids, which are pitted dead cells that move water, decreases as you go higher in the tree, complicating water transport and eve...
In some planetary systems, large gas giants can act as agents of chaos, posing a threat to the habitability of their neighboring Earth-like planets. New studies show that these giants tend to kick smaller planets out of orbit and wreak havoc on their climates. Jupiter, by far the...
Likewise, I think of Grover from Sesame Street, giants from various stories I’ve read, the character “Gas” from David Cronenberg’s eXistenZ and as many more associations as I can muster. And the speed of it comes from consistent, unrelenting practice. Not just any kind of practice, ...
systems we found ours was rather unusual. Most planets orbit red dwarfs, not sun-like stars, and large gas giants often orbit close to their star. Now that we have sky surveys of galaxies throughout the Universe, we can answer the same question of the Milky way, as a recent study ...
As you are soon to learn, cruise ships like the QE2 are floating resorts full of activities and fine dining. This article will explore the history, mechanics and inner workings of cruise ships, as well as how these giants manage to stay afloat. You'll also hear some cruise ship criticism...
With its center around 2.7 AU from the sun, the belt separates Mars and the other rocky planets from the massive, cold gas giants like Jupiter and Saturn. For a closer look at asteroids within the belt, see the next page. The Kirkwood Gaps The gravitational force of Jupiter still ...
The instruments can decipher what molecules (such as water, carbon dioxide, and methane) exist in the atmospheres of distant exoplanets — be they gas giants or smaller rocky worlds. Webb will look at exoplanets in the Milky Way galaxy. Who knows what we'll find?
For instance, perhaps a release of carbon monoxide gas before an earthquake causes a mass exodus from deeper parts of the sea. On a similar note, hydrogen peroxide could be produced if deep-sea rocks have built up enough pressure to release a massive amount of ions in the water before a ...
newborn sun – pointing out that an unsolved mystery is just how dust grains grew into mountain-sized “planetesimals”. They go on to explain the origin of the disparate bodies in the solar system, from rocky planets like Earth to gas giants like Jupiter, from asteroids to Kuiper belt ...
