What is Andromeda's Parachute?
It is a quad lensed quasar* (mag * 14/18) in the
constellation Andromeda. The cause of the quadruple
projection is a gravitational lens which stands between us
and the light source and accordingly redirects or divides
the light beam of the object by the strength of the
gravitational force of the lens. The cause of this
phenomenon is a far-off mass-rich object in space, a galaxy
or a black hole. This object was first discovered in June
2017 by the PanSTARRS telescope / 1.8m in Hawaii. This
object is similar in principle to the Einstein Cross but is
unique in its appearance. The object is about 3 seconds of
arc and is damn tiny, comes to scale of a 1 Euro coin (ca.
2cm) seen from a range of 1.5 km. Depending on the seeing or
quality of your optics this "parachute" can be separated
into three adjacent quasars or light points. The fourth
projection should be below the arc (sketch map). So this is
truly an invitation to test your quality of optics. From the
photographic point of view, somedays it will maybe succeed
to work out the complete resolution of three / four
projections. I'll stay tuned!
Quasar* rough explained, active core of a galaxy which appear like a bright star. *mag = > light magnitude. Up to apprx. mag 4-5 stars are visible in the city with the naked eye, in very dark areas to mag 6. --> The more high numerical value is given, the more weak are the objects. |
