Although the natural origin of the interstellar comet 3I/ATLAS is generally accepted, the SETI Institute team nevertheless ...
THE interstellar absorption band at λ4430 has been examined on a number of high quality image-tube spectra taken at Edinburgh. The spectra were analysed by the automated spectrophotometric method ...
IT was shown by Whitford 1 and confirmed by Nandy 2 that, over the visible part of the spectrum, the wavelength dependence of interstellar obscuration, in magnitudes against reciprocal wavelength, can ...
