These amazing images capture the moon during a total solar eclipse revealing a vast solar corona. Clarity was achieved due to the incredibly remote location chosen to view the eclipse from, a pier just outside the Enewetak Radiological Observatory on the Marshall Islands, smack dab in the middle of the Pacific Ocean.  All images are courtesy of the photographer.

“We find, therefore, under this orderly arrangement, a wonderful symmetry in the universe, and a definite relation of harmony in the motion and magnitude of the orbs, of a kind that is not possible to obtain in any other way.”
-Johannes Kepler, 1619.

NASA has spotted possible water plumes erupting on Jupiter’s moon Europa

The new Hubble images revealed “finger-like projections” coming from Europa. Researchers think the fingers are 125-mile-long plumes of water erupting from the moon’s giant subsurface ocean. Plumes are often a sign of volcanic activity. If there’s volcanic activity in Europa’s ocean, it might indicate one possibility about the future of our civilization.

Hubble Spots Possible Water Plumes Erupting on Jupiter’s Moon Europa

From NASA’s press release:

Astronomers using the Hubble Space Telescope have imaged what may be water vapor plumes erupting off the surface of Jupiter’s moon Europa.

The plumes are estimated to rise about 125 miles (200 kilometers) before, presumably, raining back down onto Europa’s surface. Europa has a huge global ocean containing twice as much water as Earth’s oceans, but it is protected by a layer of extremely cold and hard ice of unknown thickness. The plumes provide a tantalizing opportunity to gather samples originating from under the surface without having to land or drill through through miles of ice.

The team, led by William Sparks of the Space Telescope Science Institute (STScI) in Baltimore observed these finger-like projections while viewing Europa’s limb as the moon passed in front of Jupiter.

The original goal of the team’s observing proposal was to determine whether Europa has a thin, extended atmosphere, or exosphere.

“The atmosphere of an extrasolar planet blocks some of the starlight that is behind it,” Sparks explained. “If there is a thin atmosphere around Europa, it has the potential to block some of the light of Jupiter, and we could see it as a silhouette. And so we were looking for absorption features around the limb of Europa as it transited the smooth face of Jupiter.”

In 10 separate occurrences spanning 15 months, the team observed Europa passing in front of Jupiter. They saw what could be plumes erupting on three of these occasions.

Scientists may use the infrared vision of the James Webb Space Telescope, which is scheduled to launch in 2018, to confirm venting or plume activity on Europa. NASA also is formulating a mission to Europa with a payload that could confirm the presence of plumes and study them from close range during multiple flybys.    

So what to take note of this is that if those plumes really exist, then we have a better way to sample one of the most promising places for extraterrestrial life in the Solar System.

Messier 15 

The globular cluster M 15 lies about 36,000 light-years from Earth in the direction of the constellation Pegasus. It spans nearly 175 light-years across and contains over 100,000 stars as well as a rare planetary nebula, Pease 1, named for its discoverer, the American astronomer Francis Pease. M 15 has one of the densest concentrations of stars within its core region of any cluster in the Milky Way, with an estimated 30.000 stars within an 11 light-year radius of the center. It has been suggested that this severe crowding at the center might be the result of a core collapse due to the mutual gravity of the great number of stars or possibly a black hole.

NASA to Hold Media Call on Evidence of Surprising Activity on Europa

NASA will host a teleconference at 2 p.m. EDT Monday, Sept. 26, to present new findings from images captured by the agency’s Hubble Space Telescope of Jupiter’s icy moon, Europa.

Astronomers will present results from a unique Europa observing campaign that resulted in surprising evidence of activity that may be related to the presence of a subsurface ocean on Europa.

Audio of the teleconference will stream live on NASA’s website at http://www.nasa.gov/live
