Known as acometary globule, the swept-back cloud, extending from the upper right to the head left and below center, is shaped by intense ultraviolet radiation from theOB associationof very hot stars inNGC 6231, off the left edge of the scene. That energetic ultraviolet light also powers the globule's bordering reddish glow ofhydrogen gas.

This work indicated that the explosion intensity was related to flame spread direction and the explosion field was not spherically symmetric. The maximum explosion overpressure close to the ground was about 3.3 times higher than that along the vertical direction when the ratio of height and radius of the cloud was 0.2.The explosion intensity increased with increasing ratio of height and radius of gas cloud, and the maximum overpressure should increase by 3.1 times when the ratio changed from 0.1 to 1.0.When the ratio decreased, the distance of flame spread increased and the time of inflammation delayed, which led to decreasing energy transfer of gas cloud and falling explosion overpressure.
研究结果显示：爆炸流场不具备球形对称的性质，爆炸超压与火焰传播方向有关，当气云高径比0.2时，沿地面方向的最大超压可达垂直方向的3.3倍；气云体积不变而形状变化时，爆炸强度随着高径比的增大而增大，高径比1.0时的最大超压可达高径比0.1时的3.1倍；气云高径比降低时，火焰传播距离增大，燃烧时间增长，气云释能速率下降，因此爆炸超压降低。
The symbol for the isotope deuterium. It also appears to solve the deuterium problem but only if the rocky materials out near the earth's present orbit picked up some local water from the solar nebula (the cloud of gas and dust surrounding the young sun) before they accreted to form the earth.
同时，看上去它也解决了气含量的问题——但是只有当外来的岩石物质处于地球现今轨道附近时，并且在它们增生形成地球之前，从太阳的星云里(围绕着年轻太阳的气体和尘埃)获取了水时，这个问题才最终得到解决。

World's Craziest Geoengineering Scheme A manmade volcano erupting continuously to shade the Earth until greenhouse gas levels in the atmosphere are brought down. Thousands of mirrors boosted into geosynchronous orbit to block sunlight. Crewless ships wander the oceans spewing saltwater into the air to increase cloud cover. These are just a few of the proposals from scientists to manipulate, or geoengineer, the planet to stave off global warming.
