ALMA under the MilkyWay 
This view shows several of the ALMA antennas and the central regions of the Milky Way above. In this wide field view, the zodiacal light is seen upper left and at lower left Mars is seen. Saturn is a bit higher in the sky towards the centre of the image.

NGC 4449
NGC 4449 (also known as Caldwell 21) is an irregular galaxy in the constellation Canes Venatici. It is located about 12 million light-years away, part of the M94 Group (the Canes Venatici I Group), a galaxy group relatively close to the Local Group containing the Milky Way. This well-studied galaxy is similar in size and brightness, and often compared to, the Milky Way’s satellite galaxy, the Large Magellanic Cloud (LMC). NGC 4449 has a general bar shape, also characteristic of the LMC, with scattered young blue star clusters.

Grand Swirls from NASA’s Hubble by NASA Goddard Photo and Video on Flickr.Tramite Flickr:
This new Hubble image shows NGC 1566, a beautiful galaxy located approximately 40 million light-years away in the constellation of Dorado (The Dolphinfish). NGC 1566 is an intermediate spiral galaxy, meaning that while it does not have a well-defined bar-shaped region of stars at its center — like barred spirals — it is not quite an unbarred spiral either.
The small but extremely bright nucleus of NGC 1566 is clearly visible in this image, a telltale sign of its membership of the Seyfert class of galaxies. The centers of such galaxies are very active and luminous, emitting strong bursts of radiation and potentially harboring supermassive black holes that are many millions of times the mass of the sun.
NGC 1566 is not just any Seyfert galaxy; it is the second brightest Seyfert galaxy known. It is also the brightest and most dominant member of the Dorado Group, a loose concentration of galaxies that together comprise one of the richest galaxy groups of the southern hemisphere. This image highlights the beauty and awe-inspiring nature of this unique galaxy group, with NGC 1566 glittering and glowing, its bright nucleus framed by swirling and symmetrical lavender arms.
This image was taken by Hubble’s Wide Field Camera 3 (WFC3) in the near-infrared part of the spectrum.

Evolution of the light echo around V838 Monocerotis

Hubble has returned to the intriguing variable star V838 Monocerotis many times since its initial outburst in 2002, to follow the evolution of its light echo.
The unusual variable star V838 Monocerotis (V838 Mon) continues to puzzle astronomers. This previously inconspicuous star underwent an outburst early in 2002, during which it temporarily increased in brightness to become 600 000 times more luminous than our Sun. Light from this sudden eruption is illuminating the interstellar dust surrounding the star, producing the most spectacular ‘light echo’ in the history of astronomy.
