The main image was taken with the Chandra X-ray Space Telescope (in blue) and Hubble Space Telescope optical images (in gold) of the spiral galaxy NGC 3393. Meanwhile, in the small box we see the central region of NGC 3393 in the Chandra image alone.

Artist's impression of the accelerating star HE 0437-5439. The hot blue star was ejected from the Milky Way with enough speed to escape the galaxy's gravitational pull. It is now flying through the outer fringes of the Milky Way at a speed of 2.5 million km/h far above the disk of the galaxy, about 200 light years from the center. It is now destined to move in the bingalactic space. Image: NASA, European Space Agency et al. Bacon of the Space Telescope Science Institute.
