NRAO: Milky Way Explorer Software Tours the Solar System

NRAO's Milky Way Explorer Tours the Solar System

Imagine seeing the Sun, planets, and a myriad other objects in our Solar System as you have never seen them before, in invisible radio light!

That is the experience you will get through the National Radio Astronomy Observatory's (NRAO) newly released Solar System installment of its popular Milky Way Explorer, an online tour of our interstellar neighbourhood guided by the actual astronomers who explore it using radio waves.

Through an entertaining and informative series of videos, NRAO's Science Visualization Team presents multimedia-rich tours of the radio Sun as well as many of the planets, moons, and asteroids that orbit it.

At each stop along the way, planetary radio astronomers reveal the new science and exciting details we have learned about our Solar System neighbours through the use of radio telescopes.

Unlike familiar optical telescopes, which can only study objects illuminated by our Sun and other stars, radio telescopes can see the otherwise invisible cold, dark features in space.

This includes the faint radio light that is naturally emitted by the molecules and chemicals that make up the atmospheres of planets and certain moons in our Solar System.

Radio dishes, when paired with powerful radar transmitters on Earth, can also reveal hidden landscapes, such as the Moon's dust-layered surface and Venus's alien features shrouded behind its thick clouds.

The Milky Way Explorer, which was launched in 2013, also includes dozens more videos showcasing the diverse radio astronomy studies of our spiral island of stars, stellar nurseries, and dark matter.

A third set of interviews and animations is scheduled for 2015 to share more radio astronomy discoveries made inside our Galaxy and among the nearest neighboring galaxies of our Universe.

NASA MAVEN: 'Tour' ancient, wet Mars in YouTube video


NASA's Goddard Space Flight Center has release a YouTube video it says shows how Mars may have looked 4 billion years ago.

When the Red Planet was young, it appears to have had a thick atmosphere that was warm enough to support oceans of liquid water -- a critical ingredient for life -- and the YouTube video shows how the planet could have appeared at the time, the space agency said Wednesday.

Beginning with a flyover of a martian lake, rapidly moving clouds suggest the passage of time and the shift from a warm and wet to a cold and dry climate.

As millions of years fly by the lakes dry up, while the atmosphere gradually transitions from Earth-like blue skies to the dusty pink and tan hues seen on Mars today.

NASA's YouTube "tour" of Mars comes as it prepares to launch its MAVEN spacecraft that will study the planet's atmosphere.

The launch is set for Nov. 18 from Florida's Cape Canaveral Air Force Station.
