New stars emerge from inside the Rosette Nebula, seen in this image taken by the National Science Foundation’s 0.9-meter telescope’s Mosaic camera at Kitt Peak National Observatory.
The brightest cluster of stars in the center of this photo lives about 5,000 light-years away from Earth.
To identify the atoms and ions in these clouds, scientists filter the telescope images to reveal just the light coming from certain ionized gases.
The nebula would look reddish-pink to the naked eye. But only three atoms and ions are imaged here: Neutral hydrogen atoms show up in characteristic red, O²⁺ in green, and S⁺ in blue.

British prostate cancer patients are to receive a revolutionary ‘seek and destroy’ treatment that promises to obliterate tumours. The so-called Trojan-horse therapy hides cancer-killing viruses in the immune system, enabling them to sneak into cancerous growths. Experts were stunned by the results of tests in mice, in which all prostate tumour was eliminated and the animals cured of the disease. Now, 15 men in Sheffield and Manchester are to start a clinical trial using the technique - the first time it has been tested in humans.
