NASA has just released unearthed recordings of the moment that the Apollo 10 astronauts Eugene Cernan and John Young heard mysterious sounds while flying around the far side of the moon 47 years ago (May 1969).
In a recent study, NASA show that it would cost about ten times cheaper to organize a lunar mission today than it was 40 years ago. If in 1969 it was necessary to spend 25.4 billion sollars — around $95 billion in today’s money — to allow Neil Armstrong step foot on the moon, now it would cost no more than 9 billion euros.
Believe it or not, astronomers are abuzz about another sea that may be a home for life, and it’s not on Saturn’s Titan or Enceladus, or Jupiter’s icy satellite Europa. New data suggests Jupiter’s moon Ganymede, the largest in the solar system, has an underground ocean which contains more water than all of Earth’s surface water combined, according to NASA.
Saturn’s moon Enceladus is a mystery. From Earth it looks tiny and cold, and yet it’s not a dead hunk of rock. Actually, Enceladus makes the short list for most interesting places in the Solar System. Passing spacecraft see trenches and ridges, similar to Earth’s, and in 2005 NASA’s Cassini mission spotted ice geysers streaming from its south pole.
We all know and love the moon. We’re so assured that we only have one that we don’t even give it a specific name. It is the brightest object in the night sky, and amateur astronomers take great delight in mapping its craters and seas. To date, it is the only other heavenly body with human footprints. What you might not know is that the moon is not the Earth’s only natural satellite.
Not much is known about Earth’s “inner space” —its core — although scientists agree on one thing. Much of the core consists of iron. But just how much iron is there remains the subject of debate. Now, new research show that the asteroids that slammed into Earth and the moon more than 4 billion years ago were vaporised into a mist of iron.
For many years, mankind has wondered about the existence of life in worlds outside the Earth. It is possible though that alien life may indeed exist but not as we know it. In a new study published this week by researchers from Cornell University, the team of researchers has modeled a new methane-based life form that can metabolize and reproduce, similar to the oxygen-based life forms here on Earth.
Why should our solar system’s planets get all the attention? There are things about our own Moon that we either still don’t know or have just learned about, half a century after 12 human beings walked on it. Other moons may harbor life or contain evidence about incredibly violent events that have changed the very nature of the solar system. A few moons are just plain spectacular, like Charon. What’s Charon, you ask?
