From the Hubble telescope a black hole pulls in a star and shreds it .

The pictures in the article appear to be art, not photos taken with the Hubble telescope. Does anyone have a link to the Hubble photos?

There really isn’t a “ picture” or image because they used the ultraviolet and infrared spectrum to Study the wave length to determine how and when the star was eaten by the hole and how it happened. It’s all in the article.

I didn't see that in the article. If they used the telescope to actually form one or more images (regardless of the wavelengths used) even if the image/images aren't as exciting or beautiful or as easily understood as the artists' conceptions, it still would have been nice to see the image(s) printed out. If all they have is a a spectrograph trace or something, it would be nice to see that too. E.g., they could put a little red arrow pointing at a spectral peak on some dull gray trace and say something like "indication that the black hole is consuming a star," or similar language.
