John P. Millis, Ph.D. for redOrbit.com - Your Universe Online The holy grail of planetary astronomy is to find a solar system that mirrors our own. While a lot of effort has been placed on finding a planet with Earth-like properties – the right size, an atmosphere, the right temperature – are of equal importance in the search for a Sun-like star. Such a glowing orb would need to have a similar mass, temperature, and spectral type. These parameters are somewhat easy to measure, but...

Forces Of Martian Nature
2014-07-11 03:24:38

ESA The surface of Mars is pocked and scarred with giant impact craters and rocky ridges, as shown in this new image from ESA’s Mars Express that borders the giant Hellas basin in the planet’s southern hemisphere. The Hellas basin, some 2300 km across, is the largest visible impact structure in the Solar System, covering the equivalent of just under half the land area of Brazil. The images presented here were taken on 13 January 2014 by the high-resolution stereo camera on Mars...

Distant Earths May Need Balanced Friction Tides To Support Life
2014-07-10 12:52:42

Gerard LeBlond for redOrbit.com - Your Universe Online Friction generates heat and NASA scientists have developed a computer model that shows how friction may help distant Earth-sized planets survive dangerous orbits. Other star systems commonly house Earth-sized planets. To some, friction heat could be destructive, but given the correct amount of heat, it could be helpful in creating conditions to support life. “We found some unexpected good news for planets in vulnerable orbits....

Supernova Explosions Release Building Blocks Of Planet Formation
2014-07-10 10:13:49

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online The formation of planets of stars is still somewhat of a mystery to astronomers. While much progress has been made, particularly in the last few decades, there are still unanswered questions as to how the planetary building blocks form. But now, new research may be closing that knowledge gap. Early in the life of the Universe, the cosmos was dominated by the basic elements of hydrogen and helium, with only trace amounts of...

Ganymede and Jupiter
2014-07-09 05:38:47

April Flowers for redOrbit.com - Your Universe Online Jupiter's moon Ganymede is the largest satellite in our solar system, approximately three-quarters the size of Mars. Ganymede has two types of terrain on the surface: highly cratered dark regions comprising nearly 40 percent of the surface, with the rest being lightly grooved in intricate patterns. A new study, led by researchers with the Southwest Research Institute (SwRI), reveals that the processes which shaped these ridges and...

New Evidence Suggests Mercury Was Formed From A Stellar Collision
2014-07-08 10:50:50

Gerard LeBlond for redOrbit.com - Your Universe Online Planet Mercury has an unusual metal-rich composition which has baffled the scientific community. However, new evidence may have solved this mystery. According to a new study published online in Nature Geoscience on July 6, Mercury along with other space objects in the solar system with an unusual metal-rich composition, may be left over from stellar hit-and-run collisions in the early formation of the solar system. The...

How Solar Cycles Impact Our Weather Here On Earth
2013-01-13 09:10:34

Solar cycles: what are they and why should we care about them? Solar cycles are made up of what are known as solar minimums (min) and solar maximums (max). We refer to a solar min at the time when the sun is not active with many sunspots, while a solar max is just the opposite when we see a large increase in sunspot activity. So how long do solar cycles last? Typically they run on what is known as an 11 year cycle from the max to the min and then start over again anew. As of 2012 we...
