Sir William Huggins obtained the first photographic spectrum of a comet (Comet 1881 III) on June 24, 1881, using a reflector telescope equipped for spectroscopy and astrophotography. Analysis of ...

A team of European astronomers [1] has used the UVES spectrograph on the 8.2-m VLT KUEYEN telescope to perform a uniquely detailed study of Comet LINEAR (C/2000 WM1). This is the first time that this ...

I HAVE to thank Dr. Marshall Watts for having called attention to a point of some interest with regard to the spectra of comets, viz., which of the carbon spectra agrees with the cometary spectrum? In ...

What do you get when you kick up a whole lot of debris from an icy comet under the watchful eye of a powerful infrared telescope-spectrometer? An up-close look at the chemical composition of the ...

THE spectrum-analytic method of examining the light from comets has only been applied hitherto to comets of weak light; yet the observations are fitted to extend considerably our knowledge of these ...

For decades, comets have been at the center of a nitrogen mystery. The ratio of carbon-to-nitrogen within comets should be similar to that of the sun, because the sun and the rest of the solar system ...

Astronomers are rushing to study what appears to be the first known interstellar comet — and in some of the very earliest observations, it looks oddly familiar. The object, currently dubbed Comet ...

On the evening of June 24, 1881, Sir William Huggins directed his reflector, equipped with spectroscopic and photographic tools and located in his private observatory in London, to the head of Comet ...
