Last month there was quite a stir concerning a US intelligence report based on 144 UFO sightings by US military personnel.

At just nine pages in length, it was a fairly scant report, but it did make for some interesting reading nonetheless.

Chris Impey, Professor and Deputy Head of the Department of Astronomy at the University of Arizona joined Jonathan to discuss.

Also on the show, Jonathan was joined by Dr. Susan Kelleher and Dr. Shane Bergin to look at the top science news stories of the week.
