Milky Way Galaxy.

The stellar halo of the Milky Way Galaxy has at least two components with apparently two different populations with distinct kinematic properties (vrot: rotation; \sigma: rms dispersion). It possibly gives a hint about the dual formation scenario of the Galaxy i.e. in situ and accretion.

The Alcubierre warp drive allows a spaceship to travel at large global velocity by deforming the spacetime in a bubble around the spaceship.

The figure shows the spacetime diagram for massive particles with initial negative velocity . The magenta and the black lines represent the bubble walls and ship respectively.  All the particles pass through the bubble.

A magnification map generated for Q2237+0305 , one of the
most monitored lensed quasars. The brightness at a location
indicates the magnification, due to microlensing, of a pixel-sized
source situated at that location. Bright areas indicate high magnification, dark areas indicate low magnification, relative to the mean magnification of image A.

Distribution of dwarf galaxies around Andromeda (M31).

The Pan-Andromeda Archaeological Survey  (PAndAS) led to discovery of new  satellite galaxies orbiting around the Andromeda galaxy.  In 2010, during the second year of data from  PAndAS,  five new dwarf galaxies (Andromeda XXIII-XXVII)  have been found in the outer halo of  M31.
