Two fundamentally different processes of rocky planet formation exist, but it is unclear which one built the Earth and other terrestrial solar system planets.
Possible scenarios of terrestrial planet formation: in the classic Wetherill-type model of oligarchic growth, the terrestrial planets formed by mutual collisions among Moon- to Mars-sized planetary embryos after the gas disk dissipated and accreted only a small fraction of CC planetesimals, which
Using James Webb Space Telescope For Solar System Research - SpaceRef
In one of the most exciting developments in astronomy in the 21st century, NASA is launching the James Webb Space Telescope (JWST) today--and Northern Arizona University astronomers, planetary astronomers and their students will be using the massive observatory to expand their research and
"Webb is NASA's newest premier space science observatory--destined to be a household name, like its predecessor, Hubble," NASA announced. "This is an Apollo moment for NASA science: Webb will fundamentally alter our understanding of the universe.
California ready to pull the plug on rooftop solar system subsidies – Orange County Register
The one with no solar panels and the escalating electric bill? It’s subsidizing the one with solar panels and the low electric bill, California officials say — and they hope to change that next month.
Right now, rooftop solar owners like Raj Pandey of Irvine get some 40 cents per kilowatt hour for electricity they send to the grid for neighbors to use. That credit would plummet to about 5 cents per kilowatt hour under a proposal heading to the California Public Utilities Commission on Jan.

The Sky this Week: New Year's Planetary Show - Now Habersham
2021 is getting ready to come to a close and the planets are gearing up for a good show in celebration.
But first a quick update on Comet Leonard. Leonard continued to brighten this week with an outburst occurring on the 20th. This likely signaled some breaking up of the comet’s core as it gets closer to the sun.
Light show's solar system put back in order by seven-year-old stargazer | London Free Press
STRATFORD – It took a seven-year-old with a surprisingly expansive knowledge of our solar system to literally put the planets back in order for a holiday lights display here.
On his first visit to the Lights On Stratford winter festival's Journey to the Stars display on Tom Patterson Island, Jaxon Brooks noticed something wasn't quite right with two of the planets.
Don't Install A Smaller Solar System To Get A Higher Feed In Tariff
Finding a high feed-in tariff is becoming harder. Our feed-in-tariff comparison tool makes the job easier, but increasingly electricity retailers are putting system size limits on their most generous solar feed-in rates.
In South East Queensland, New South Wales, and South Australia, some retailers’ highest solar feed-in tariff is only available to systems below a certain size – typically 10 kilowatts. This may tempt you to install a smaller solar system than you might otherwise.
