... Bacteriophages: The Most Common Life Like Form on Earth . ... Credit: Wikipedia ; Insert: Mike Jones Explanation: There are more bacteriophages on Earth than any other life-like form.

In early mid-infrared observations (c 1970) two prominent dust emission features were discovered. ... Soon after the discovery of the silicate features another feature at about 11.3 microns was discovered in the spectra of some carbon stars, not as wide or as strong as the silicate features but still thought to be due to a solid material. ... less common features: extreme carbon stars, the AlO/silicate complex, the "unidentified infrared" features, unusual silicate features . ...

The new observations show that the larger star is a bit smaller than astronomers had previously thought. ... The smaller companion star then just eats whatever comes its way like a friendly vampire! ...

... Supernova explosion   in a binary is treated as an instantaneous mass loss of the exploding star. ... In this case, the eccentricity and semi-major axis of the binary after the explosion can be straightforwardly calculated (Boersma, 1961[ 21 ]). ... Then, the transition to a new system barycenter frame is made (at this point the spatial velocity of the new center of mass of the binary is computed), . ... During the CE stage, an effective spiral-in   of the binary components occurs. ...
