Science in the News
Science in the News Policy Changes
It has come to the attention of the club that recent Science in the News segments have been coming from untrustworthy or unmentioned sources. This has caused an increase in skepticism for a time meant to be spent in marvel and enlightenment. It is being asked that Science in the News segments are from now on sourced by a credible outlet. Thank you!

as the lecture was carried out.
Just as the lenses on eyes bend light to form an image, gravitational lensing refers to the occurrence of light being reflected off of an enormous gravitational field, imaging things like distant galaxies. Sometimes, the distortion is large enough to display more than one image of the same galaxy, called "multiple imaging" in this description by the University of Tennessee (Knoxville).
|"Here is another example of a gravitational lens called the Einstein Cross . In this image, a single object appears as four objects. A very distant quasar is thought to be positioned behind a massive galaxy. The gravitational effect of the galaxy has created multiple images through gravitational lensing on the light from the quasar. The stars in the foreground galaxy also seem to be acting as gravitational lenses, causing the images to change their relative brightnesses in these two photographs taken three years apart (UTK)."|
