Cosmic Journeys – Solar Superstorms

A fury is building on the surface of the Sun – high-velocity jets, a fiery tsunami wave that reaches 100,000 kilometers high, rising loops of electrified gas. What’s driving these strange phenomena? How will they affect planet Earth? Find the answers as we venture into the seething interior of our star.

Solar Superstorms is a major new production that takes viewers into the tangle of magnetic fields and superhot plasma that vent the Sun’s rage in dramatic flares, violent solar tornadoes, and the largest eruptions in the solar system: Coronal Mass Ejections.

The show features one of the most intensive efforts ever made to visualize the inner workings of the sun, including a series of groundbreaking scientific visualizations computed on the giant new supercomputing initiative, Blue Waters, based at the National Center for Supercomputing Applications (NCSA), University of Illinois.

Brace yourself for the onslaught of the next ….Solar Superstorm.

A God’s Eye View of the Universe

What if we could see the universe as a whole? We’ve been trying to see and describe the large scale shape and structure of the universe since the dawn of science. Now, with powerful telescopes and supercomputers we have what earlier generations might have thought was a truly “God’s Eye” view of creation. Those same technologies suggest that our view is still highly limited.

The Fate of Mars’ Atmosphere

There is plenty of evidence that Mars at one time had an atmosphere that allowed water to flow on its surface. What happened to it? To find out, NASA’s MAVEN spacecraft is flying high above the Red Planet with a battery of sensors. While previous Mars orbiters have peered down at the planet’s surface, MAVEN is spending part of its time gazing at the stars, looking for subtle changes in their color as they dip through the limb of Mars and set below the horizon. Such stellar occultations reveal what the atmosphere is made of, and how its composition varies with altitude. MAVEN’s observations are providing the most detailed picture of the Mars upper atmosphere to date, helping scientists understand how Mars turned from a warm and wet planet in its youth, into the forbidding desert that we see today.

Hubble’s Pluto Discoveries

From HubbleCast. Before NASA’s New Horizons probe flew past Pluto in July 2015, almost all of the information scientists had about this mysterious dwarf planet came from observations made by Hubble. What discoveries did Hubble make in the Pluto system and how will the greatest telescope ever built advance our knowledge of this distant, icy world following New Horizons’ flyby?

Magnetism and the Search for Life

From ESO-Cast. Giant telescopes are being used to search for the subtle signs of magnetic fields in other stars and even to map out the star spots on their surfaces. This information is beginning to reveal how and why so many stars, including our own Sun, are magnetic, and what the implications might be for life on Earth and elsewhere in the Universe. Astronomers are beginning to use signs of magnetic fields generated by stars to assess the habitability of planets that orbit them.

Discoveries of a Restless Young Solar System

From Hubblecast. Using images from the NASA/ESA Hubble Space Telescope and ESO’s Very Large Telescope, astronomers have discovered unique and totally unexpected structures within the dusty disc around the star AU Microscopii. These fast-moving wave-like features are unlike anything ever observed, or even predicted. What are they, and what do they tell us about the restless early years of a solar system in the making?

Finding Earth’s Twin

Among the methods astronomers have used to discover extra solar planets, the most successful is a technique called transit photometry. It measures changes in a star’s brightness caused when a planet crosses in front of its star along our line of sight.

Astronomers using NASA’s Kepler Space Telescope have employed this technique to become the most successful planet-hunting spacecraft to date, with more than a thousand established discoveries and many more awaiting confirmation. Future missions carrying improved technology are now in the works.

How much can they tell us about alien planetary systems similar to our own?A great deal, according to a recently published study. It shows that in the best-case scenarios, these upcoming missions could uncover planetary moons, ringed worlds similar to Saturn, and even large collections of asteroids.

Mars: Death of a Planet

This is the story of a discovery made on St. Patrick’s Day, 2015. We learned just how much Mars is at the mercy of our sun. During a solar outburst that hit Mars that day, the NASA spacecraft Maven measured an accelerated loss of molecules in its upper atmosphere.

In its early days, Mars appears to have had enough surface water to cover the entire planet to a depth of 140 meters, and an atmosphere that was thick enough to hold it there. But a more active sun in those days began a long slow process of steadily eroding the Martian air and sending it out into space. The water dried up, and whatever life forms had developed had no chance to thrive and evolve on the surface.

Cinematic Mars

Mars Express, the first planetary mission of the European Space Agency, was sent to the Red Planet in 2003. It sent a lander down to the surface, and although it failed to fully deploy , the orbiter has been taking pictures and mapping the surface ever since. It has produced high-resolution mineralogical maps, radar soundings of permafrost, and probing the composition of the atmosphere.

Its images, now released for general use, show the dramatic landscapes of Mars, sculpted by ancient volcanoes, water flows, and the scouring action of dust storms. Now we an revel in these cinematic images and imagine what it’s like to fly over the surface of Mars.
