Plumes of ocean spray are emanating from Jupiter's moon Europa

Plumes of ocean spray are emanating from Jupiter's moon Europa

Science
May 14 (UPI) -- New research offers additional evidence of plumes emanating from Europa's subsurface ocean. Images captured by the Hubble Telescope have previously suggested the presence of ocean plumes ejected through tissues in the icy crust of Jupiter's moon. Some astronomers were skeptical of the Hubble results, however. The newest proof was discovered among data collected by the Galileo mission in 1997 during a Europa flyby. Scientists detailed the new proof in a paper published Monday in the journal Nature Astronomy. Scientists with the Cassini mission were able to identify water plumes protruding from Saturn's moon Enceladus by measuring perturbations in the magnetic fields surrounding the satellite. Molecules and atoms ejected in a watery plume quickly become ionized as solar win...

SpaceX Dragon successfully splashes down in Pacific Ocean

Science
May 6 (UPI) -- The unmanned SpaceX Dragon cargo ship successfully splashed down in the Pacific Ocean, the company said.SpaceX confirmed the reusable ship completed the company's third resupply mission to and from the International Space Station at about 3:30 p.m. Saturday.After spending a month on the space station, Dragon detached and was sent back to earth to deliver 4,000 pounds of NASA cargo and research material.The cargo included science samples from a variety of technological and biological studies about the space station."Some of the science returning on this flight includes samples from the Metabolic Tracking study that could lead to more effective, less expensive drugs, the APEX-06 investigation examining how to effectively grow crops in space, and the Fruit Fly Lab-03 investigat...
Climate change dials down Atlantic Ocean heating system

Climate change dials down Atlantic Ocean heating system

Science
A significant shift in the system of ocean currents that helps keep parts of Europe warm could send temperatures in the UK lower, scientists have found.They say the Atlantic Ocean circulation system is weaker now than it has been for more than 1,000 years - and has changed significantly in the past 150. The study, in the journal Nature, says it may be a response to increased melting ice and is likely to continue.Researchers say that could have an impact on Atlantic ecosystems.Scientists involved in the Atlas project - the largest study of deep Atlantic ecosystems ever undertaken - say the impact will not be of the order played out in the 2004 Hollywood blockbuster The Day After Tomorrow.But they say changes to the conveyor-belt-like system - also known as the Atlantic Meridional Overturnin...
Plastic patch in Pacific Ocean growing rapidly, study shows

Plastic patch in Pacific Ocean growing rapidly, study shows

Science
A collection of plastic afloat in the Pacific Ocean is growing rapidly, according to a new scientific estimate.Predictions suggest a build-up of about 80,000 tonnes of plastic in the "Great Pacific Garbage Patch" between California and Hawaii.This figure is up to sixteen times higher than previously reported, say international researchers.One trawl in the centre of the patch had the highest concentration of plastic ever recorded."Plastic concentration is increasing - I think the situation is getting worse," said Laurent Lebreton of The Ocean Cleanup Foundation in Delft, Netherlands, which led the study. "This really highlights the urgency to take action in stopping the in-flow of plastic into the ocean and also taking measures to clean up the existing mess."Waste accumulates in five ocean ...
Ocean plastic could treble in decade

Ocean plastic could treble in decade

Science
The amount of plastic in the ocean is set to treble in a decade unless litter is curbed, a major report has warned.Plastics is just one issue facing the world's seas, along with rising sea levels, warming oceans, and pollution, it says.But the Foresight Future of the Sea Report for the UK government said there are also opportunities to cash in on the "ocean economy".They say this is predicted to double to $ 3 trillion (£2 trillion) by 2030.The report says much more knowledge is needed about the ocean. The authors say the world needs a Mission to "Planet Ocean" to mirror the excitement of voyaging to the moon and Mars.The Foresight reports are written by experts to brief ministers on medium and long-term issues of significance. This one has been signed off by ministers from four different d
