An international team of astronomers, led by David Sobral from Leinden University of the Netherlands used three telescopes located across the globe to study the trends in star formation, from the earliest stars that made up the first galaxies in the universe, up until now. Their findings suggests something quite shocking .. almost 95% of stars that will ever live have already been born!
NGC 6240 A composite image of a giant gas cloud spanning 300,000 ly with a mass of 10 billion Suns inside the galaxy merger system NGC 6240. This collision involves two spiral galaxies about the size of the Milky Way, each containing a supermassive black hole in the center, which are on their way to form an even more massive black hole
Rho Ophiuchus Nebula Complex This amazing complex of nebulosity revealed on long exposure color photographs is one of the most beautiful areas of the entire night sky. It contains dark nebulae where lanes of obscuring dust hide background stars, blue reflection nebulae where the dust is illuminated by nearby stars and red emission nebulae where the hot hydrogen gas itself is glowing.
NGC 3627: Revealing Hidden Black Holes The spiral galaxy NGC 3627 is located about 30 million light years from Earth. This composite image includes X-ray data from NASA’s Chandra X-ray Observatory (blue), infrared data from the Spitzer Space Telescope (red), and optical data from the Hubble Space Telescope and the Very Large Telescope (yellow). The inset shows the central region, which contains a bright X-ray source that is likely powered by material falling onto a supermassive black
This image of Spiral Galaxy M106. NASA suggests that spiral galaxies get their shapes when “a close gravitational interaction with a neighboring galaxy created waves of high mass and condensed gas which continue to orbit the galaxy center.” When a galaxy is extra large, its gravity can distort nearby galaxies. Some spiral galaxies are believed to have a bar across their center, as in the case of our own Milky Way.
