How deep is the ocean on Europa? Europa’s possible ocean is estimated to be 100-200km deep. Despite the great depth of the Europa’s ocean, hydrostatic pressure at the seafloor would be 130-260 MPa, corresponding to 13-26 km depth of a theoretical Earth’s ocean.
Likewise, Can you breathe on Europa?
Europa has a thin oxygen atmosphere, but it is far too tenuous for humans to breathe. … Europa’s magnetic field shields its surface from Jupiter’s deadly radiation.
Thereof, Is there oxygen on Europa? Europa has only a tenuous atmosphere of oxygen, but in 2013, NASA announced that researchers using the Hubble Space Telescope found evidence that Europa might be actively venting water into space. This would mean the moon is geologically active in the present day.
Does life exist Europa?
Europa’s surface is blasted by radiation from Jupiter. That’s a bad thing for life on the surface – it couldn’t survive. But the radiation may create fuel for life in an ocean below the surface. The radiation splits apart water molecules (H2O, made of oxygen and hydrogen) in Europa’s extremely tenuous atmosphere.
Does Europa have fish?
That amount of oxygen would be enough to support more than just microscopic life-forms: At least three million tons of fishlike creatures could theoretically live and breathe on Europa, said study author Richard Greenberg of the University of Arizona in Tucson.
Can a human survive on Europa?

The radiation splits apart water molecules (H2O, made of oxygen and hydrogen) in Europa’s extremely tenuous atmosphere.
What is the red stuff on Europa?
Despite their unnerving appearance, the red scars criss-crossing Europa are, of course, not biological. They are actually cracks and ridges marking weak lines within the moon’s ice crust, emphasised and exacerbated by the swelling and falling of tides due to Jupiter’s gravitational pull.
Is there fish on Europa?
That amount of oxygen would be enough to support more than just microscopic life-forms: At least three million tons of fishlike creatures could theoretically live and breathe on Europa, said study author Richard Greenberg of the University of Arizona in Tucson. …
Are there clouds on Europa?
Europa does have an atmosphere, although tenuous. This atmosphere is composed solely of oxygen. Unlike our atmosphere, the oxygen in Europa’s atmosphere is likely not produced biologically. Europa’s atmosphere is maintained by charged particles that hit its cold surface and produce water vapor.
Which planet has most oxygen?
Answer: From the table we see that Mercury has the greatest percentage of oxygen in its atmosphere.
Are there volcanoes on Europa?
Europa is one of the rare planetary bodies that might have maintained volcanic activity over billions of years, and possibly the only one beyond Earth that has large water reservoirs and a long-lived source of energy.
What if Europa hit Mars?
If something as large as Europa were to hit Mars, it would probably be enough to turn the entire surface of Mars into molten lava and completely destroy the Europa-sized object.
How do we know Europa has water?
Hubble had previously detected water vapor on Europa — in apparent plumes that arise sporadically and temporarily extend perhaps 120 miles (200 kilometers) into space from the moon’s icy shell, which overlies a huge, buried ocean of liquid water.
Can we live on Titan?
Although there is so far no evidence of life on Titan, its complex chemistry and unique environments are certain to make it a destination for continued exploration.
How can Europa have liquid oceans so far from the sun?
It is far far out from the sun and yet it’s got this liquid water ocean, and the reason that Europa has liquid water is because it’s orbiting Jupiter and the tidal tug and pull causes Europa to flex up and down and all that tidal energy turns into mechanical energy, which turns into friction and heat that helps …
Is life possible on Titan?
Although there is so far no evidence of life on Titan, its complex chemistry and unique environments are certain to make it a destination for continued exploration.
What would be the main characteristics for Europan life?
For life to be present the three basic requirements are: 1) liquid water; 2) chemical building blocks; and, 3) a source of energy. Europa is thought to have all three.
Can you breathe on Titan?
It is cold on Titan (surface temperature of about -290 degrees F). And people would need to wear respirators to breathe oxygen, since the atmosphere is mostly nitrogen. The light on Titan is a little dim, like just after a sunset here on Earth, due to the haze particles in the thick atmosphere.
What Moon could we live on?
The strongest candidates for natural satellite habitability are currently icy satellites such as those of Jupiter and Saturn—Europa and Enceladus respectively, although if life exists in either place, it would probably be confined to subsurface habitats.
How cold is it on Europa?
Europa’s surface temperature averages about 110 K (−160 °C; −260 °F) at the equator and only 50 K (−220 °C; −370 °F) at the poles, keeping Europa’s icy crust as hard as granite.
Why are there cracks on Europa?
According to researcher Gregory Hoppa the curved cracks on Europa are caused by its orbit being slightly excentric due to the influence of Io and Ganymede (other moons of Jupiter). … When Europa is farther, the tides fall because Jupiter’s force falls. This causes Europa’s ice shell to flex.”
Why is there red ice on Europa?
Spectrographic evidence suggests that the dark, reddish streaks and features on Europa’s surface may be rich in salts such as magnesium sulfate, deposited by evaporating water that emerged from within.
What are the brown marks on Europa?
Brown, linear (double) ridges extend prominently across the scene. They could be frozen remnants of cryovolcanic activity which occurred when water or partly molten water ice erupted on the Europan surface, freezing almost instantly in the extremely low temperatures so far from our sun.
