An explosion early today at 05:03 h (local time) ejected incandescent fragments to 1.5 km distance from the crater on the northeastern slope and generated a column of ash that reached more than 2 km height above the crater and was dispersed to the SW.
In addition, 28 smaller steam-gas-ash explosions occurred during the past 24 hours and a constant steam and gas plume is rising from the volcano.

SOLAR WIND STORM: For the third day in a row, a remarkably fast (600 km/s - 700 km/s) stream of solar wind is blowing around Earth. This is causing magnetic unrest around the poles as well as elevated levels of high-energy electrons in Earth orbit. NOAA cautions satellite operators that "satellite systems may experience significant charging" in response to accumulated electrons. SWx alerts: text, voice.

 

BEAUTIFUL VENUS-JUPITER PAIRING: The sunset triangle of May 26th is breaking up, but the show is not over. As the triple conjunction disperses, Venus is passing Jupiter only 1 degree away. Watching the two brightest planets move so close together is a wonderful way to end the day. Look west at sunset! NASA: video, full story.

Pictures of Sunday's night's triangular conjunction are still pouring in. This one shows Pat and Fred Espenak watching the show from the sky deck of Bifrost Astronomical Observatory:

This daguerreotype print was the first of a series of silver platinum plates he shot using a telescope. Draper was also the first person to shoot a portrait in America, a photograph of his sister Dorothy-Catherine .

Iridescent clouds seen by EarthSky Facebook friend Mike O'Neal in Oklahoma on May 27, 2013. Thank you, Mike.

 

Sky watchers on occasion report seeing colors in the clouds, and sometimes our friends send photos of these rainbow colors in clouds. You’ll find some examples in this post. These colorful clouds are called iridescent clouds, and the phenomenon is called cloud iridescence or irisation. The term comes from Iris, the Greek personification of the rainbow. Click inside for some amazing photos and info about iridescent clouds.

Famed for their ability to inflict Armageddon from outer space, asteroids are now revealing the secrets of how they are responsible for both life and death on our planet.
Armed with an array of powerful telescopes, scientists are finding up to 3000 new asteroids every night. And some are heading our way.

But astronomers have discovered that it's not the giant rocks that are the greatest danger - it's the small asteroids that pose a more immediate threat to Earth.
Researchers have explained the photon propulsion that propels these rocks across space, and have discovered that some asteroids are carrying a mysterious cargo of frost and ice across the solar system that could have helped start life on earth.

The merger is occurring 11 billion light-years away, meaning that astronomers are seeing the two colliding galaxies as they were about 3 billion years after the Big Bang that created the universe. During this epoch, "red and dead" elliptical galaxies full of old stars were common.

Fu and his colleagues initially thought the two merging galaxies were a singleton, dubbed HXMM01, when they saw it with the European Space Agency's infrared Herschel space telescope.

But follow-up observations with a variety of other instruments, both on the ground and in space, revealed that HXMM01 is actually two galaxies on a collision course, separated by about 62,000 light-years at the moment.
