Under the Sea

Posted on March 16, 2015 by pMurs

Earlier this week, scientists at NASA announced that Saturn’s sixth-largest moon, Enceladus, has a warm ocean at its southern pole. More importantly, it has strong evidence of hydrothermal activity on the ocean floor, the first of its kind found outside of Earth. This is a huge discovery because most scientists agree that life on Earth […] Continue reading →

“You want me to hack the planet?”

Posted on March 16, 2015 by pMurs

There are a compendium of factors that allow for life to exist on Earth, one of the most important of which is our core. Earth’s core is made up of molten metal that swirls and churns, generating a powerful magnetic field that shields the planet from radiation and solar wind. Our core is vital to […] Continue reading →

Venus: A Resemblance to Classical Images of Hell

Posted on March 16, 2015 by jamej00

Hot potato hot potato! It all boils down to the greenhouse effect!  Yes, the greenhouse effect goes beyond causing global warming here on Earth.  It is, in fact, necessary for life on Earth; without it, the planet would be far colder than it is today.  Certain gases present in both Venus’s and Earth’s atmosphere essentially act like… Continue reading →

Beta Pictoris

Posted on March 16, 2015 by revanth111

Source: stgist.com The formation of our solar system is still an event that deserves further study, and other areas and stars in the Milky Way offer a glimpse into the processes that hold the answers. Beta Pictoris, a young star that is 63 million light years away from us, may be such a star. Beta Pictoris […] Continue reading →

Where did we come from?

Posted on March 16, 2015 by jamej00

Formation of the Solar System In only the recent history of astronomy, we’ve began to understand that our solar system is in fact no different than other star systems in the universe.  We now understand that stars in fact all form from a collapsing cloud called a nebula, which is composed mostly of hydrogen and… Continue reading →

“Y” in the Atmosphere of Venus

Posted on March 16, 2015 by revanth111

Source: dailymail.co.uk For decades, scientists have been discussing the origins of a Y shaped feature in Venus’ atmosphere. The strange feature is shown above in a picture from the Pioneer Venus Orbiter in 1979. A recent theory is that the Y shape is formed by differences in the wind speed in the atmosphere. The theory states […] Continue reading →

Salt Water Oceans Thought to be on Ganymede

Posted on March 16, 2015 by conorastr201

Astronomers have recently determined that Jupiter’s largest moon Ganymede likely has an ocean of salt water underneath its icy, inhospitable crust. Ganymede is the only moon in our solar system that has a functioning magnetic field; because of this it is also the only one to have auroras. Scientists in Cologne studied these auroras over a […] Continue reading →

Jupiter’s Watery Moon

Posted on March 16, 2015 by abbeyrstephens

Recent evidence has shown that Jupiter’s largest moon (and the largest moon in our solar system), Ganymede, has a massive ocean lying underneath a thick layer of ice. In fact, it’s believed to have more water than all of Earth! Ganymede, which is just slightly larger than the planet Mercury, has long been suspected of […] Continue reading →

NASA’s Dawn Spacecraft Orbits Ceres

Posted on March 16, 2015 by conorastr201

That’s no moon! Just this past week, the Dawn spacecraft entered orbit around Ceres, the largest object in the asteroid belt. The dward planet is one of the oldest planetary object left in our solar system, and as such could provide valuable information about the early formation of the planets; it is an in-between step, a […] Continue reading →
