NASA's Cassini spacecraft and Deep Space Network have uncovered evidence Saturn's moon Enceladus harbors a large underground ocean of liquid water, furthering scientific interest in the moon as a potential home to extraterrestrial microbes.

Researchers theorized the presence of an interior reservoir of water in 2005 when Cassini discovered water vapor and ice spewing from vents near the moon's south pole. The new data provide the first geophysical measurements of the internal structure of Enceladus, consistent with the existence of a hidden ocean inside the moon. Findings from the gravity measurements are in the Friday April 4 edition of the journal Science.

The gravity measurements suggest a large, possibly regional, ocean about 6 miles (10 kilometers) deep, beneath an ice shell about 19 to 25 miles (30 to 40 kilometers) thick. The subsurface ocean evidence supports the inclusion of Enceladus among the most likely places in our solar system to host microbial life. Before Cassini reached Saturn in July 2004, no version of that short list included this icy moon, barely 300 miles (500 kilometers) in diameter.

This illustration depicts Enceladus, which has jets of water vapor and ice gushing from its south pole and the large interior ocean beneath an ice shell.

Happy 24th anniversary to the Hubble Space Telescope! This colorful mosaic of a small portion of the Monkey Head Nebula unveils a collection of carved knots of gas and dust silhouetted against glowing gas. The cloud is sculpted by ultraviolet light eating into the cool hydrogen gas.

I'm hosting the Public Lecture Series tonight at STScI.
Tonight's speaker is Mario Livio, who will discuss "Brilliant Blunders."  
Starts at 8pm.

Latest News: Comet Siding Spring is plunging toward the Sun along a roughly 1-million-year orbit. The comet, discovered in 2013, was within the radius of Jupiter's orbit when the #Hubble Space Telescope photographed it on March 11, 2014. Hubble resolves two jets of dust coming from the solid icy nucleus. The feature should allow astronomers to measure the direction of the nucleus's pole, and hence, rotation axis. The comet is not expected to be bright enough to be seen by the human eye.

Starting in 30 minutes on Twitter: Ask our #JWST and #Hubble scientists questions about exoplanets, life and the how the universe formed!

Just tweet your question on the hashtag #JWSTfirst -
@astraughnomer, @jasonkalirai,&@albertoconti will be responding to questions. We'll be retweeting things at:@NASAWebbTelescp.

See you all in Austin!
 
We're going to SXSW again this year!  This event will one of our social media focal points where you can participate either vicariously through the people who are at the event or you can stop by and say hi if you are in Austin.

We invite people to post their #JWST or #Hubble and #SXSW related photos.  We'll also be live streaming a few events while we're there so you can comment and interact on these pages during that as well.

We are really looking forward to SXSW this year - we will have a booth at the Gaming Expo which will be held from March 7th through the 9th.  Stay tuned for scheduled events to be posted here as the big event arrives.
