Giant molecular clouds are large clouds of gas and dust in space that are typically surrounded by ionized regions. They have the potential to emit nuclear gamma-ray lines and positron production due to the presence of cosmic-rays. These clouds are of interest for future observations, especially ...
A nebula ais one of the most beautiful deep-sky objects in the night sky. But what is a nebula? And how do these space clouds form?
This NASA/ESA Hubble Space Telescope reveals clouds of gas and dust near the Tarantula Nebula, located in the Large Magellanic Cloud about 160,000 light-years away.ESA/Hubble & NASA, C. Murray The star formation in this region is spurred on by the presence of dust, which clumps together a...
A comparison is made between cold dust clouds, where presumably gas phase processes dominate the chemistry, and regions of high mass star formation such as Orion where both shocks and evaporation of dust grain mantles may play a role. In dust clouds, carbon rich molecules often show enhanced ...
A natural conclusion was, therefore, that it was aglowing cloudof dust and gas. Literature These brightglowing cloudsare called nebulas. OpenSubtitles2018.v3 We arrive at a vastglowing cloudof gas and dust: OpenSubtitles2018.v3 Nebula vastglowing cloudsof gas hanging in space. ...
the Interstellar Probe Science and Technology Definition Team Chapter Microwave molecular spectroscopy IV.E.7 Interstellar Space Applications The region between the stars contains interstellar clouds composed primarily of dust and gas. Over 100 molecules (neutrals, ions, and radicals), mostly carbon-...
A cosmic lightsaber, trillions of miles long, slices through the dark clouds of dust and gas that surround it in a new image captured by NASA's Hubble Space Telescope.
This view of the Andromeda galaxy is rather unique because it also features clouds of gas and dust that lie inside our own Milky Way galaxy. Astrophotographer Rogelio Bernal Andreo took this image from California in December 2016. In an email to Space.com, Andreo said the image may be ...
They have turned into a gas called water vapor (水蒸气). As the water vapor goes higher in the sky, the air goes cooler. The cooler air causes the water droplets(水滴) to start to stick to things such as bits of dust, ice or se a salt.Clouds get their names in two ways. One ...
In subject area: Physics and Astronomy Collapsing clouds refer to the process where a cloud of gas and dust undergoes gravitational collapse, leading to the formation of dense cores that eventually give rise to stars or stellar systems.
