The Lighthouse Nebula was formed by the wind of a pulsar, a rapidly notating neutron star that rotates at speeds faster than 1,000 km/sec. Located roughly 23,000 light years away towards Carina the Keel near Canopus and Eta Carinae, the image of the wind nebula are clearly shown on the lower right hand side of the X-ray image taken from the Chandra Xray Observatory.
Messier 63 is about 25 million light-years distant in the constellation Canes Venatici. Also cataloged as NGC 5055, the island universe is nearly 100,000 light-years across. Roughly the same size as the Milky Way Galaxy. Known as The Sunflower Galaxy, M63 sports a bright yellowish core. Its has expansive blue spiral arms and pink star forming regions. A dominant member of a known galaxy group, M63 has faint, extended features that could be the result of gravitational interactions with nearby galaxies.
