Are mud volcanoes true volcanoes? A mud volcano is what caused the explosion near an oil field in the Caspian Sea off Azerbaijan on July 4. That's according to a report by an Azerbaijani press agency. It happened on Dashly Island, a volcanic island. The last recorded eruption on this island was in 1945. A famous Roman naturalist, Pliny the Elder, described a mud volcano in the year 77 AD. Yet they are still a poorly understood natural phenomenon. What are mud volcanoes? Photos and video here. Finally, an electron-capture supernova For the 1st time, researchers have found convincing evidence for a new type of supernova - a new sort of stellar explosion - powered by electron capture. Astronomers predicted it 40 years ago, but never felt sure they'd observed one until now. The newly found supernova is 21 million light-years away. The findings solve a mystery about one of the sky's most famous objects, the Crab Nebula, thought to be a remnant of a supernova that exploded in the year 1054 AD. Here's why this supernova is different. Tiangong: China’s new space station. What to expect On July 4, 3 astronauts on China’s new space station performed the country’s 1st space walk. Now they're busy configuring the station for future crews. Named Tiangong (“heavenly palace”), the station is the Chinese National Space Agency’s signature project. It's key to China’s ambitions for having humans in orbit around Earth for extended periods of time. Read more.

Summer Triangle: Deneb is distant and very luminous Deneb is the northernmost star in the famous Summer Triangle. That's a prominent asterism visible in the east on July and August evenings. Deneb's constellation is Cygnus the Swan. In a dark sky, you can imagine the Swan flying along the starlit trail of the summer Milky Way. The constellation Cygnus also makes an obvious cross shape, and that's another asterism, called the Northern Cross. Summer Triangle, Cygnus, Northern Cross. Lots of names in these overlapping star patterns. Here's how to see them.
