... It was nothing known about the nearest to the Sun planet before the spaceship flight "Mariner-10", launched in the 3d of November 1973 and flied to the Mercury in the 29 of March 1974. The snapshots of the surface showed an astonishing similarity the Moon's and Mercury's reliefs. ... During the second flight they determined the duration of a Mercury day (88 terrestrial days) the day temperature was 510°C and the night one was about 210°C. The heat flood radiated by the surface was also determined. ...

All stars derive their energy through the thermonuclear fusion of light elements in to heavy elements. High temperatures are required so that the mutual electrostatic repulsion of the protons in each fusing atomic nucleus is overcome. ... Elements with more protons in their nuclei require higher temperatures. ... This sequence is now shown in the animation below. ... First Step of the Proton-Proton Chain Narration .

. A hydrogen atom and a helium atom go into a bar. The hydrogen atom is clearly upset and moans, "I've lost my electron, my only electron." The concerned helium atom says, "Just calm down now ... are you sure you've lost it?" . The hydrogen atom replies, "Yes, I'm positive!" . (Later, a neutron walks in to the same bar. He sits down and says to the bar tender, "Hey, how much for a beer?" The bar tender looks at him and says, "For you, no charge!")

We present the detection and analysis of molecular hydrogen emission towards ten interstellar regions in the Large Magellanic Cloud. We examined low-resolution infrared spectral maps of 12 regions obtained with the Spitzer infrared spectrograph (IRS). ... The excitation diagrams of the detected H2 transitions are used to determine the warm H2 gas column density and temperature. ... We find the excitation of H2 by this process is equally efficient in both atomic- and molecular-dominated regions. ...
