«This work adds a plausible hypothesis to explain the way in which
liquid water could
have formed on early Mars, in a manner similar to the seasonal melting that produces the streams and
lakes we observe during our field work in the Antarctic McMurdo Dry Valleys,» Head said.
Schimdt
has found evidence that warm ocean currents and convective forces beneath Europa's frozen shell can cause large blocks of ice to overturn and melt, bringing vast pockets of
water, sometimes holding as much
liquid as all of the Great
Lakes combined, to within several kilometers of the moon's icy surface.
Siegert says that it
would be a «phenomenal result» if the
lakes were found to be devoid of life, because they offer everything that bacteria need — including
liquid water and nutrients — and their
water temperatures are just a few degrees below zero.
In this study we
have monitored the
liquid water column of these permanent ice - covered
lakes.
The heat from those eruptions
would have melted massive amounts of ice to form englacial
lakes — bodies of
water that form within glaciers like
liquid bubbles in a half - frozen ice cube.
Research in the past several months
has further fueled the excitement, yielding new hints of
liquid water on Enceladus and revealing ethane
lakes and methane rain on Titan.
Heat from a volcano erupting beneath an immense glacier
would have created large
lakes of
liquid water on Mars in the relatively recent past.
Chuck Booth wrote: «The existence of
lakes beneath Antarctic ice is nothing new — this
has been known for decades... What is new, and newsworthy, is that the extensive system of
liquid water under the ice may provide a better understanding of ice sheet dynamics»
In the last decade, scientists
have discovered
lakes of
liquid water underneath the Antarctic ice sheet.
Because Antarctica
has so many subsurface
lakes, conditions must
have been favorable for
liquid water to collect on Antarctica and form
lakes.
These
lakes, that
would be located deep in Europa's icy crust, could be communicating with the
liquid water ocean below, while providing it with chemical elements from the surface that
would be a valuable energy source to any potential life forms.
The intrepid robotic explorer successfully completed its primary scientific objective when it discovered strong evidence early on in its mission that a place called Yellowknife Bay near its landing site, constitutes an ancient dried - out
lake bed which was once filled with drinkable
liquid water billions of years ago and could
have sustained life — if any were present.
