The Sun is more active today than it has been in 8,000 years.
Today is only a short moment from the future. To get there from here, you can follow a preset path that leaves little margin or opportunity for error. Another route is to strike out on your own toward a destination that has few signposts showing the way. John Spencer and Karen Rugg are heading in a very new direction and in their book, they present a comprehensive, near term space industry focused entirely on space tourism. After all, the future is what you make of it.
The Sun is more active today than it has been in 8,000 years, according to new research from the Max Planck Institute. Researchers discovered that a certain isotope of carbon, C-14, depends on the amount of cosmic rays that reach the Earth's surface. When solar activity is high, the Sun's magnetic field provides a shield against these cosmic rays, and when it's low, the Sun lets more cosmic rays reach the Earth. By measuring C-14 levels in dead trees which were buried in the ground, the scientists were able to build up a historic record of solar activity. scientists have found that solar activity levels only slightly influence the Earth's climate and global temperature.
Using the Hubble Space Telescope, Astronomers have located what they think is the burned out star at the heart of Tycho's supernova Remnant, which exploded in 1572. This discovery provides the first direct evidence that these kind of supernovae, called Type 1a, occur when a White Dwarf consumes material from a binary companion until it reaches a certain point and explodes. They discovered the star, which is similar to our own Sun, because it's moving away from the explosion three times faster than other objects in the region - it was sling shotted away when its dancing partner vapourized.
