The probe also detailed the chemical composition of
the hydrocarbon lakes on Saturn's biggest moon, Titan.
For example,
the hydrocarbon lakes on Titan could host a different form of life.
The observatory's long history is punctuated with discoveries, from the detection of millisecond pulsars — neutron stars that rotate several hundred times a second — to the presence of
hydrocarbon lakes on Saturn's moon Titan.
Not exact matches
The array of claims around Alberta's crude is wide and varied:
on the one hand, anti-Keystone groups contend that dilbit — i.e. diluted bitumen, thick oilsand crude mixed with light
hydrocarbons that will allow it to flow through a pipeline — is more corrosive than other types of oil and sinks in water rather than floating, which makes it harder to clean rivers and
lakes after a spill.
«The rocks are water ice and the
lakes are methane and light
hydrocarbons, yet we see processes very similar to what we see
on Earth.»
Methane rain should fall
on the
lakes but it is vastly more volatile than ethane and propane, so it probably evaporates much faster from
lakes, leaving the heavier
hydrocarbons behind.
The
hydrocarbon lakes are part of a landscape that exhibits both the general principles of geology and the different ways they work
on other worlds.
Almost all of the
hydrocarbon seas and
lakes on the surface of Saturn's moon Titan cluster around the north pole, as can be seen in this mosaic from NASA's Cassini mission.
«Until Cassini arrived at Saturn, we didn't know about the
hydrocarbon lakes of Titan, the active drama of Enceladus» jets, and the intricate patterns at Saturn's poles,» Linda Spiller, the Cassini project scientist at NASA Jet's Propulsion Laboratory in Pasadena, Calif., said in a statement
on Dec. 23.
The methane in Titan's atmosphere has a similar cycle to water
on Earth; it evaporates into the atmosphere from the large
lakes, condenses as clouds and falls as methane rain
on Titan's
hydrocarbon - rich landscape, creating rivers and sculpting valleys.
Between the evidence of past flowing water
on Mars, Titan's
hydrocarbon lakes, Europa's underground ocean, and Enceladus, it seems increasingly probable we'll find life somewhere else in the solar system.
