Astrophysicists simulated the fate of a hydrogen cloud as massive as 10,000 suns that suddenly wafted near a black hole.
Unlike the Solar System where most of the gravitational pull comes from the Sun and is simple to model, it is much harder to describe the gravitational field near the centre of the Galaxy, where millions of stars, vast clouds of dust, and even dark matter swirl about.
To make the modeled zodiacal cloud as dense as the real one, the dust had to come from comets falling apart, not just those shedding dust near the sun, the team reports in the 20 April issue of The Astrophysical Journal.
Based on its direction of motion, the cloud is expected to hit a region about a quarter of the way around the galaxy from the Sun, near the Perseus arm of the galaxy.
Since his prediction, Alfvén waves have been associated with a variety of sources, including nuclear reactors, the gas cloud that envelops comets, laboratory experiments, medical MRI imaging and in the atmosphere of our nearest star — the Sun.
On the other hand, the levels of carbon monoxide and methanol in the coma might have changed over time, especially because Jupiter - family comets spend more time near the Sun than Oort Cloud comets do.

Furthermore, the T Tauri star - disk systems within 100 pc of the Sun tend to be older, on average, than the large numbers of star - disk systems that are still found in or near their natal dark clouds.
Even with near zero CO2, and the Sun 3 - 4 % dimmer than now, the tropics require albedo help from clouds and encroaching sea ice for global freeze - 0ver — hence, an interesting science problem that needs careful cold - climate cloud and ocean dynamics modeling.
Groisman, P. Ya, R.S. Bradley and B. Sun, 2000 The relationship of cloud cover to near - surface temperature and humidity: comparison of GCM simulations with empirical data.
«This H2O negative - feedback effect on CO2 is ignored in models that assume that warm moist air does not rise and form sunlight - reflecting clouds, but remains as humid air near sea level, absorbing infrared radiation from the sun, and approximately doubling the temperature rises predicted from atmospheric CO2 increases.
But unless you include the Sun early last century and clouds in the latter part — which are related to SST decadal Pacific variation — then you are nowhere near explaining surface temperature changes.
It would imply that the CO2 forcing of near 2 W / m2 has already all been balanced by something, presumably a combination of increased aerosols, increased surface temperature, reduced other GHGs, increased clouds, increased surface albedo, and / or a weaker sun.
Near the subsolar point (dark blue colors), where the Sun is directly overhead, clouds reflect more than 1000 Watts of energy per square meter of Venus's surface area, an amount almost as large as the energy that Earth receives from the Sun.
