Hubble finds persistent water vapour in Jupiter's moon

India TV News  

The Hubble Space Telescope observations of Jupiter's icy moon Europa have revealed the presence of persistent water vapour, suggesting potential conditions hospitable for life, according to NASA. They extend more than 60 miles high and produce transient blobs of water vapour in the moon's atmosphere, which is only one-billionth the surface pressure of Earth's atmosphere, NASA said. The new results, published in the journal Geophysical Research Letters, show similar amounts of water vapour spread over a larger area of Europa in Hubble observations spanning from 1999 to 2015. This suggests a long-term presence of a water vapour atmosphere only in Europa's trailing hemisphere -- that portion of the moon that is always opposite its direction of motion along its orbit.

Europa Clipper's Mission: Searching for Life Beyond Earth's Boundaries

The Economist  

Europa Clipper mission aims to find life on Jupiter's icy moons. The spacecraft will investigate Europa's icy crust, which holds the potential for a vast ocean of liquid water. Scientists hope to discover whether life exists in this extreme environment, marking a significant step in the search for extraterrestrial life beyond Earth.

Daily Mail  

Europa, Jupiter's fourth-largest moon, has been hailed as one of the most likely locations for aliens to exist in our solar system. Jupiter's moon Europa is considered one of the solar system's most promising potentially habitable environments. Finally, after an approximately 1.8billion-mile journey, Europa Clipper enters orbit around Jupiter in April 2030 Dr Buratti notes that there are three main …

Jupiter’s moon Europa has weak, oxygen-rich atmosphere

Hindustan Times  

There are plenty of reasons to be excited about the possibility of finding microbial life on Europa. Also, models derived from Europa data show that its ocean floor is in contact with rock, enabling chemical water-rock interactions that produce energy, making it the prime candidate for life. Although Europa boasts three basic ingredients for life – water, the right chemical …

Hopes of finding life on Europa are DASHED: Study finds Jupiter's icy moon doesn't have enough oxygen to sustain aliens

Daily Mail  

It's been hailed as one of the most likely locations for aliens to exist in our solar system. Slightly smaller than Earth's moon, Europa is comprised of an icy shell, estimated to be about 10 to 15 miles thick and a very thin atmosphere, composed primarily of oxygen. Scientists are almost certain that hidden beneath the icy surface of Europa …

The Hindu  

On April 13, 2023, the European Space Agency is scheduled to launch a rocket carrying a spacecraft destined for Jupiter. Three of Jupiter’s moons – Europa, Ganymede and Callisto – are home to large, underground oceans of liquid water that could support life. Upcoming missions from ESA and NASA JUICE and Europa Clipper are set up to give scientists game-changing …

NASA Finds Water Vapour on Jupiter's Moon Ganymede for the First Time

News 18  

Did you know that Jupiter’s moon Ganymede contains more water than all of the oceans combined on the Earth? So, water on Jupiter’s largest moon’s surface is just in solid form, or at least that is what scientists thought before they found the evidence of water vapour in Ganymede’s thin atmosphere. The reason behind this, scientists thought, was the presence …

Hubble finds evidence of water vapour on Jupiter Moon

India TV News  

Astronomers have, for the first time, uncovered evidence of water vapour in the atmosphere of Jupiter's moon Ganymede using NASA's Hubble Space Telescope. This water vapour forms when ice from the moon's surface sublimates -- that is, turns from solid to gas. Ganymede's ocean would reside roughly 100 miles below the crust; therefore, the water vapour would not represent the …
