• What A Dust Devil Looks Like On Mars

    More than 4,000 Martian days after NASA’s Mars rover Opportunity began exploring the surface of the red planet, the little robot caught sight some something truly stunning. Opportunity snapped a photo of a dust devil swirling in the Meridiani Planun, the rover’s home since it landed on the planet in 2004. Enjoy and share……

  • Why the Universe Needs Dark Energy

    Part 2 Now that we know the universe will continue to expand forever, we can begin to complete the first Friedmann equation, and determine the shape and geometry of our universe. At first glance, it would seem that the equation doesn’t quite add up, and that our universe is a hyperbolic plane. But when we add in the cosmological constant, the equation balances out, and we return to a flat universe. Enjoy and share…………..

  • Will the Universe Expand Forever?

    Will the Universe continue to expand outward or will it succumb to gravity and collapse upon itself? Throughout history, there has been much speculation about what the fate of the universe would be. Many theorized that the universe would eventually succumb to the pull of gravity, and reverse its expansion in what was being called ‘The Big Crunch.’ However, with the help of mathematical equations from Newton, Einstein, and Alexander Friedmann, we now have an answer. Enjoy and share……..

  • Zooming in on the Fornax Galaxy cluster

    This video sequence takes us deep into the faint southern constellation of Fornax (The Furnace). Here we find a rich concentration of bright galaxies — the Fornax Galaxy Cluster. The final very detailed image is a new image of the cluster from the VLT Survey Telescope. Enjoy and share…..

  • 7 Wonders of the Solar System

    The Great Red Spot (GRS) is a persistent anticyclonic storm, 22° south of Jupiter’s equator; observations from Earth establish a minimum storm lifetime between 300 and 400 years. The GRS rotates anticlockwise, with a period of about six Earth days or 14 Jovian days. Its dimensions are 24–40,000 km east-to-west and 12–14,000 km north-to-south. The spot is large enough to contain two or three planets the size of Earth. At the start of 2004, the Great Red Spot had approximately […]

  • A solar storm caused something incredible to happen on Jupiter

    The northern lights here on Earth might seem otherworldly, but the ones on Jupiter are truly out of this world. In a study published in Journal of Geophysical Research – Space Physics, researchers announce that they have observed the effects of a solar storm on Jupiter’s aurora, the planet’s version of our northern lights. It’s the first time the interaction between Jupiter’s aurora and a solar storm, also known a a coronal mass ejection or CME, has been observed. Enjoy […]
