Europa’s ocean may have similar salts to Earth’s ocean

A recent study done with the Hawaii Keck telescope looked at spectra from Jupiter’s famous icy moon Europa. Many scientists have speculated that the moon may harbor life in an ocean underneath its thick ice shell. Now, spectra are showing a magnesium sulfate compound on the surface of the ice. While it is though the sulfate component may have come from the volcanic moon Io, it is still speculated that the magnesium may be from salts within the ocean. Thus, there is hope there are similar salts in Europa’s ocean to what is in Earth’s ocean. Read more about this here.

Seeing a talk on the Deepsea Challenge

Big conferences can be incredibly overwhelming, but there is also this sense of excitement and mystery. I usually spend a lot of time going to talks within my own field, but sometimes it’s fun to walk into a random room.

While walking around the gigantic conference centers, I came across the press area. I peeked my head into a small room and saw on the screen “Up Next: Deepsea Challenge Panel.” I was incredibly disappointed that I had missed much of the earlier talk by the panel, which included several well-known scientists and James Cameron, on the DEEPSEA CHALLENGER that was piloted by James Cameron to the bottom of the Mariana Trench. I decided to sit down and see what happened. To my delight, it was a press conference with the panel. I leaned forward in my chair, hidden in the back corner of the room, and listened intently.

For those of you who do not know about the DEEPSEA CHALLENGER, James Cameron became the first person to go to the ocean’s deepest trench alone. Also involved in the science team and panel were three well know scientists, Dr. Patty Fryer, Dr. Doug Bartlett and Dr. Kevin Hand. You can read about the entire science and engineering team here.

I watched as the group of four answered questions about the mission, all the while making science seem adventurous and exciting. There was talk of discovering a potentially new species of an amphipod crustacean in addition to an organism that contained a compound which has promise of treating Alzheimer’s. The importance of this mission in understanding a potential area for the beginning of life and the discovery of life on other places such as Europa was also discussed.

I left the meeting with a new sense of anticipation for science to come. James Cameron mentioned that touching the bottom of the trench and saying you have explored the trenches is like dropping from a plane into a corn field in Nebraska and saying you have seen the United States. It’s clear there is still much left on our own planet which has yet to be explored.

** This past week I have been spending my time at the American Geophysical Union conference in San Francisco. This conference includes between 15,000-20,000 people every year. The conference focuses on everything ranging from space and planetary science to climate change to education.
