Today's Astronomy Picture of the Day is described as follows:
Most galaxies have a single nucleus -- does this galaxy have four? The strange answer leads astronomers to conclude that the nucleus of the surrounding galaxy is not even visible in this image. The central cloverleaf is rather light emitted from a background quasar. The gravitational field of the visible foreground galaxy breaks light from this distant quasar into four distinct images. The quasar must be properly aligned behind the center of a massive galaxy for a mirage like this to be evident. The general effect is known as gravitational lensing, and this specific case is known as the Einstein Cross. ...
Health care problems can weigh very heavy on the individual affected by them and their loved ones. To deliver personalised care we first need to resolve the four care domains (five including the spiritual). If personalised care is to be realised (aligned and integrated) in practice and not just two words in policy (political lensing), then we need to remember personalised care can be an illusion in itself.
