Scientists have discovered another venting activity on Europa. With the help of the Hubble Space Telescope, they have uncovered the latest movement on one of Jupiter's moon, Europa. New reports are now saying that the spotted activity could be a sign of potential alien life forms on the planet.

The Hubble Space Telescope is one of the space telescopes that's been orbiting the Earth for almost three decades. Throughout the years, it has been very instrumental to many discoveries in the space. One of those it closely examining is the Jupiter's moon Europa.

In 2013, it first observed some water vapor above the south region of Europa and from thereon astronomers never stop studying its findings. After almost four years, The Hubble Space Telescope once again monitored new movements on the surface on the Jupiter's moon Europa that could prove an alien life in space.

According to Phys.Org, the venting activity that was spotted by The Hubble Space Telescope on Europa recently have been very elusive for astronomers for the past decade. The once crust of ice enclosed on the Europa's interior has now been very active resulting to discharging of plumes. The said plumes were seen exploding 62 miles above the moon's surface that could further boost proof of natural phenomenon on the site.

Also, the said plume spotted by the Hubble Space Telescope on Europa recently was the same location where the same activity happened two years ago. Scientists are now convinced that the position could be a warm spot that might give them circumstantial proof of oceans in the moon's surface. Now, astronomers are also looking at a possibility that life forms exist on those potential oceans.

According to Baltimore Sun, Baltimore astronomers are the one who lead the discovery of plumes on Europa using The Hubble Space Telescope. They believed that the liquid plume they've spotted on the moon's surface could be a sign of life-supporting chemical energy prevailing over the site.

Earlier results also show that plumes erupting on Europa are composed of 98 percent water which scientists are confident that they are closer to finding biological life outside the Earth. For now, they are still relying on the Hubble SpaceTelescope data and observation as NASA is still preparing the Europa Clipper mission that will further establish their claims about Jupiter's moon mystery.
