This spectacular image of the Carina nebula reveals the dynamic cloud of interstellar matter and thinly spread gas and dust as never before.  Credit:  ESO/J. Emerson/M. Irwin/J. Lewis About 7500 light-years away, in the constellation of  Carina , lies a nebula within which stars form and perish side-by-side. Shaped by these dramatic  events, the  Carina Nebula  is a dynamic, evolving cloud of thinly sprea d interstellar gas and dust. Spanning over 300 light-years, the Carina Nebula is one of the Milky Way's largest star-forming regions and is easily visible to the unaided eye under dark skies. Unfortunately for those of us living in the north, it lies 60 degrees below the celestial equator, so is visible only from the Southern Hemisphere. The massive stars in the interior of this cosmic bubble emit intense radiation that causes the surrounding gas to glow. By contrast, other regions of the nebula contain dark pillars of dust cloak...

Tafreshi Brilliant blue stars litter the southern sky and the  galactic bulge  of our home galaxy, the Milky Way, hangs serenely above the horizon in this spectacular shot of ESO’s Paranal Observatory. This image was taken atop Cerro Paranal in Chile, home to ESO’s  Very Large Telescope  (VLT). In the foreground, the open dome of one of the four 1.8-metre  Auxiliary Telescopes  can be seen. The four Auxiliary Telescopes can be utilised together, to form the  Very Large Telescope Interferometer  (VLTI). The plane of the Milky Way is dotted with bright regions of hot gas. The very bright star towards the upper left corner of the frame is  Antares  — the brightest star in  Scorpius  and the fifteenth brightest star in the night sky.

Image: This colourful stripe of stars, gas, and dust is actually a spiral galaxy named NGC 1055. Captured here by ESO’s Very Large Telescope (VLT), this big galaxy is thought to be up to 15 percent larger in diameter than the Milky Way. NGC 1055 appears to lack the whirling arms characteristic of a spiral, as it is seen edge-on. However, it displays odd twists in its structure that were probably caused by an interaction with a large neighbouring galaxy. Credit: ESO Spiral galaxies throughout the Universe take on all manner of orientations with respect to Earth. We see some from above (as it were) or “face-on” — a good example of this being the whirlpool-shaped galaxy NGC 1232. Image: This spectacular image of the large spiral galaxy NGC 1232 was obtained on September 21, 1998, during a period of good observing conditions. It is based on three exposures in ultra-violet, blue and red light, respectively. The colours of the different regions are well visible : the cent...
