"description": "Before NASA’s Fermi Gamma-ray Space Telescope launched in 2008, only a handful of pulsars, including the Crab, Vela, and Geminga, were known to emit gamma-rays, the highest-energy form of light. Shown here are 294 gamma-ray pulsars detected by Fermi. Young pulsars, formed when massive stars explode, are the slowest rotators, typically spinning about 10 times a second. Paradoxically, their older siblings, called millisecond pulsars (MSPs), spin much faster, up to hundreds of times a second, thanks to the effects of a stream of matter pulled from a companion star. In spider systems, the companion is all but consumed. The most energetic spiders may fully evaporate their companions, leaving behind only an isolated MSP. Studying pulsars provides insights into the interplay of gravity, radiation, and magnetic fields with matter in the most extreme state we can observe directly.The WorldWide Telescope is a tool for showcasing astronomical data and knowledge.

"description": "A visualization of the 294 pulsars in the Fermi gamma-ray pulsar catalog. The visualization starts with a full-sky Hammer projection view of the catalog. Different types of pulsars are indicated by different markers. The pulsar markers oscillate in size according to the object's pulsation frequency at actual speed. Millisecond pulsars are just shown as solid markers. The map then morphs into the full 3D view of the pulsar distribution, and we then fly out to give a top down view showing the distribution of gamma-ray pulsars in our galaxy. || pulsar3DMap_2160p30.00200_print.jpg (1024x576) [174.0 KB] || pulsar3DMap_2160p30.00200_searchweb.png (320x180) [72.3 KB] || pulsar3DMap_2160p30.00200_thm.png (80x40) [5.4 KB] || full (3840x2160) [0 Item(s)] || pulsar3DMap_2160p30.mp4 (3840x2160) [240.8 MB] || ",
