The layout of the solar system is at least moderately atypical. There should be roughly four Earth masses worth of planets inside Mercury’s orbit. And Jupiter, with its large mass, its close-to-circular orbit, and its 10+ year period is an oddball at the 10% (and probably more impressive) level. At the start of the 1990s, […]
Why are scientists so optimistic? The Kepler space telescope gets much of the credit. Before it was launched into orbit in 2009, astronomers couldn't be sure whether planets existed outside our solar system. The search for extraterrestrial...Show More Summary
The puzzling, fascinating surface of Jupiter's icy moon Europa looms large in this newly-reprocessed color view, made from images taken by NASA's Galileo spacecraft in the late 1990s. This is the color view of Europa from Galileo that shows the...
NASA's reprocessed picture of Jupiter's Europa gives us a fresh look at the likeliest place in the solar system for extraterrestrial life.
Some citizens who are concerned about the long-term viability of the electric grid will no doubt want to purchase their own solar systems with inverters and back-up batteries. I won't discourage those who want to do this–the systems may prove to be of assistance. But I see no reason to subsidize these purchases. read more
Because PV panels are able to capture more solar energy when they are pointed directly at the sun, installers may configure systems to optimize output by adjusting the orientation and tilt of a system, or by using mechanisms that track the sun as it traverses the sky. read more
Scientists developed a new method which allows to estimate the magnetic field of a distant exoplanet, i.e., a planet, which is located outside the Solar system and orbits a different star. Moreover, they managed to estimate the value...Show More Summary
Born from the rubble of a violent collision, hurled through space for millions of years and dismembered by the gravity of planets, asteroid Bennu had a tough life in a rough neighborhood: the early solar system. "Bennu's Journey," a new...
The Australian Renewable Energy Agency (ARENA) today announced $452,000 funding for Fulcrum3D to further develop an advanced cloud tracking system. ARENA
This is a great way to think about how big the planets of our solar system are: in terms of fruits. (via boing boing) Tags: astronomy food science space

Now, 22 of the 36 ecovillage homes have solar systems. At least two of these homes are net-zero -- meaning the systems generate as much energy as the homes use over the course of the year for heat, hot water, cooking, lighting and plug loads.
The students from West Virginia University designed and built PEAK, a very cool net-zero energy log cabin for the Solar Decathlon 2013, you may remember my story: Have You Ever Wanted To Live In A Net-Zero Log Cabin? (VIDEO). While visiting their competition home, I noticed that the team members were wearing wrist bands and I Continue reading ?
The country of Bangladesh has installed over 3 million new residential solar energy systems since May, with support coming from the World Bank and other various agencies, according to recent reports. To be exact, the number is 3.1 million...Show More Summary
Chondrites from a meteorite explain why the planets formed so quickly.
We write this after learning that Philae, the plucky explorer our species sent to meet asteroid 67P/ Churyumov-Gerasimenko as it hurls at 340,000 miles per hour through the solar system, has gone to sleep. We aren’t surprised. One could be forgiven for feeling a little dozy after travelling 4bn miles in space, and in a […]
In 1859, a solar storm threw an electromagnetic pulse at Earth so strong, it fried the telegraph system. A whole lot more is on the line now. Bob speaks with Rocky Rawlins of the Survivor Library about his preparations for getting zapped back to a time before computers and an electric grid. http://www.onthemedia.org/story/survivor-library/
Will a planet-dissolving dust cloud wipe out our solar system in December 2014?
A pair of sort-of comets pose a puzzle for astronomers
Planetary scientist involved in early stages of mission says early data could provide information on formation of the solar system.
