Not exact matches

Although the gas is at a chilly minus 63 degrees Fahrenheit (minus 53 degrees Celsius) and is 300 trillion times less dense than Earth's atmosphere, it's still five times hotter and 10 to 100 times denser than what's typical in galaxies like the Milky Way.

Taken with the orbiting Chandra Observatory, it shows the hottest, most violent objects in the galaxy: black holes gobbling down matter, gas heated to millions of degrees by dense, whirling neutron stars, and the high - energy radiation from stars that have exploded, sending out vast amounts of material that slam into surrounding gas, creating shock waves that heat the gas tremendously, generating X-rays.

The entire cliff would have been deposited very quickly from a fast - moving current of hot gas and ash (a pyroclastic density current), and the extreme temperatures (900-1000 °C) caused the ash to weld to the ground and effectively enameled the area in dense volcanic glass.

Their experiment implies that the cosmos started out not as a hot, dense cloud of gas but as a strangely sublime, friction - free liquid.

As the hot gas that filled the early universe cooled, denser regions started to collapse, which set the gas ringing.

This dense cloud is a star - forming region called Lupus 3, where dazzlingly hot stars are born from collapsing masses of gas and dust.

As a galaxy moves through a dense galaxy cluster, the cluster's hot gas blows away the cooler gas in the galaxy.

Hot gas collapsed toward the minihaloes, resulting in pockets of gas dense enough to further collapse on their own into the first stars.

The synchronized laser strikes caused the plastic pellet to implode, creating an extremely hot and dense core of gas, or plasma.

But current numerical simulations of how galaxy clusters form suggest they should be in areas with much hotter and less dense gas.

Insulating grains, however, such as less - dense silicates, have a hot, sun - facing side, where departing gas molecules will give a bigger shove than those on the cold side.

«We are woefully lacking in understanding how the cool, diffuse gas and dust of an interstellar cloud are converted to the much hotter, denser ball of gas that is a star.»

The gas around the star's equator is then further from its centre, so it cools more than other parts of the star's surface, while the poles remain hot and dense.

Alternatively, they might assemble themselves from the hot, dense gas surrounding the blazing protostars.

Around the accretion disk are relatively dense clouds of hot gas that could be responsible for the broad emission lines seen in Type 1 Seyferts.

Eventually the hydrogen gas gets dense and hot enough for nuclear reactions to start.

These dense winds can be rendered visible by ultraviolet light from the hot central star or from highly supersonic collisions with the ambient gas that excites the material into florescence.

Furthermore, Webb's cameras will detect the infrared glow of the dust and gas itself, allowing us to learn what it's made of, how hot and dense it is, and what chemical processes have affected it.

The group's comeback album is all chaos and void, somewhere between Metropolis and THX 1138, Sun Ra and David Hammons, great dense alloyed slabs and hot gases of ricocheting atoms.

So it's all gases at greatest density will be doing the same thing around the planet at the same time (*) and as these change with differences in density in the play between gravity and pressure and kinetic and potential from greatest near the surface to more rarified, less dense and absent any kinetic to write home about the higher one goes, then, energy conservation intact, the hotter will rise and cool because losing kinetic energy means losing temperature, thus cooling they which began with the closest in density and kinetic energy as a sort of band of brothers near the surface will rise and cool at the same time whereupon they'll all come down together colder but wiser that great heights don't make for more comfort and giving up their heat will sink displacing the hotter now in their place when they first went travelling.

If there's no radiation from the Sun, no heat capacity in the model planet, no mass big enough to effect pressure changes («real» ideal gases which don't have mass), nothing much is happening because there's no movement, (movement from the play of hot and cold volumes as hot gases rise and cold sink, becoming less dense and gaining density), but,

Thermal equilibrium doesn't mean the same temperature, if for example, a gas in getting hotter expands and rises becoming less dense and under less pressure it can move faster, it's using thermal energy to move, there's no energy lost, it's just become something else, or, as temperature relates to kinetic energy not thermal energy then heat capacity comes into play, as water can absorb a huge amount of thermal energy before there's any rise in temperature, or whatever, but if you're equating all «energy» to «heat» as thermal energy then that's a different idea altogether, not all energy is heat.

First, Venus» atmosphere is very dense, and there is a physical relationship known as the ideal gas law that indicates that gases under pressure tend to be hotter.
