A street in Long Beach was reopened Monday after an ammonia leak at a storage center near the 710 Freeway shut down the neighborhood for several hours. Firefighters received an alarm from the building in the 600 block of Anaheim Street about 3 a.m., officials said. At the scene, the first responders could smell the ammonia even before they got inside the building, said Long Beach Fire Department spokesman Matt Dobberpuhl. Several small leaks were found, and authorities shut down Anaheim Street for blocks in both directions, officials said.

Streets in a Long Beach neighborhood were closed early Monday after a cold storage facility in the area began leaking ammonia, authorities said.

Astronauts replaced a leaking component on the International Space Station after a 5-hour, 30-minute spacewalk, NASA reported. Engineers Chris Cassidy and Tom Marshburn completed their spacewalk at 11:14 a.m. PDT Saturday, after gingerly gliding out to one of the station's trusses, where ammonia coolant had been seen leaking since Thursday. The coolant is used to control the temperature of one of eight solar arrays that power the station. The pair, who had worked in tandem during spacewalks twice before, removed the 260-pound pump controller box from the P6 truss and replaced it with a spare stowed nearby.

Astronauts on the International Space Station may take a spacewalk Saturday to repair an ammonia leak. The gas, used to cool one of the station's solar arrays, began oozing from the left side of the station's truss structure Thursday, officials said. NASA reported that the six-member Expedition 35 crew, commanded by Chris Hadfield, was not in danger, and that the station is operating normally while crew members and mission managers work to reroute power through another of the station's eight power channels.

The explosion at a Central Texas fertilizer plant Wednesday night could have been caused by ammonia gas or the more well-known explosive, ammonium nitrate, according to chemists. Neal Langerman, principal chemist with Advanced Chemical Safety, a San Diego industrial consulting firm, said the initial fire could easily have caused anhydrous ammonia to explode catastrophically. “It's really hard to ignite, but it's a flammable gas,” Langerman said. “If a tank containing a liquefied flammable gas is subjected to fire, that tank could fail catastrophically, releasing the gas, which will instantly ignite, causing a catastrophic explosion, as was seen.” A robust fire also would be needed to ignite ammonium nitrate, a well-known explosive used in industry and adopted by terrorists.

Saturn's Great White Spot, a recurring storm on that planet that has intrigued scientists since it was first observed in 1876, is a windy, towering cloud of ammonia and water spewing out super jolts of thunder and lightning. Now astronomers and NASA's Cassini spacecraft, which has been orbiting Saturn since 2004, have captured the most detailed views to date of the phenomenon. The luminous storm, which may be the gaseous planet's main mechanism for dissipating heat, occurs about once every Saturnian year, the equivalent of about 30 Earth years.
