Scientists have developed a new low-temperature catalyst for producing high-purity hydrogen gas while simultaneously using up carbon monoxide (CO). The discovery—described in a paper set to publish online in the journal Science on Thursday, June 22, 2017—could improve the performance of fuel...
Inside the #CarinaNebula: Cropped from original 465 mb tif image. A towering “mountain” of cold hydrogen gas laced with dust is the site of new star formation in the Carina Nebula (NGC 3372). The great gas pillar is being eroded by the ultraviolet radiation from the hottest newborn stars in the nebula. This portion of the Carina Nebula is home to some of the most intense star formation in the Milky Way galaxy. Credit: NASA/Hubble
Nebula N159 spans over 150 light-years and is located in the neighboring Large Magellanic Cloud galaxy, about 170,000 light years away. Visible in the above picture are bright newborn stars, dark filaments of dust, and red-glowing hydrogen gas. Torrential stellar winds from hot, newborn, massive stars within the nebula sculpt ridges, arcs, and filaments in the vast cloud, which is over 150 light-years across.
Gaseous Streamers from Nebula N44C Flutter in Stellar Breeze | N44C is the designation for a region of glowing hydrogen gas surrounding an association of young stars in the Large Magellanic Cloud, a nearby, small companion galaxy to the Milky Way visible from the Southern Hemisphere.
