Astrophysicists classify most meteorites into two categories; the carbonaceous (abbreviated CC) and non-carbonaceous (abbreviated NC) types that rely on nitrogen, oxygen, titanium, nickel, tungsten, molybdenum and ruthenium compositions.
Iron meteorites can be further categorized into magmatic and nonmagmatic features, where the former was formed by fractional crystallization in well mixed molten metallic cores within differentiated asteroids.
Maximum Power Point Tracking: Benefits for your Solar System
Maximum Power Point Tracking (MPPT) greatly increases the capacity of your solar panels. To understand MPPT thoroughly, you must learn how solar PV systems works , especially solar panels .
When the solar cells of your solar PV system are not producing power during the night or on cloudy days, electricity is drawn from the main grid to power your home.

The next full moon will be on Sunday afternoon, Oct. 9, 2022, appearing opposite the Sun in Earth-based longitude at 4:55 p.m. EDT. This will be on Monday morning from the Iran and Gulf Standard Time Zones eastward to the International Date Line.
NASA's Juno Shares First Image From Flyby of Jupiter's Moon Europa
Observations from the spacecraft's pass of the moon provided the first close-up in over two decades of this ocean world, resulting in remarkable imagery and unique science.
The complex, ice-covered surface of Jupiter's moon Europa was captured by NASA's Juno spacecraft during a flyby on Sept. 29, 2022. At closest approach, the spacecraft came within a distance of about 219 miles (352 kilometers).
Alton City Council OKs Special Use Permit For Utility-Scale Solar System Array At Landfill and ...
ALTON - At Wednesday’s City of Alton Council Meeting, members approved Ordinance No. 7856, which grants a special use permit to allow a utility-scale solar system array at the former Alby Street Landfill, and also approved the second reading of Ordinance No.
The special use permit appears to move forward negotiations with Ameresco about a plan to construct a large-scale array site at the former Alby Street Landfill. Negotiations have been going on for a long period of time for this change.
The Milky Way's Spiral Arms May Have Carved Earth's Continents - Scientific American
Mighty forces beyond the solar system billions of years ago might have shaped much of the land beneath our feet today.
“It blows my mind that the continental crust we’re standing on—where the majority of Earth’s biomass is—has a potentially fundamental connection to the cosmos,” says Chris Kirkland, a geologist at Curtin University in Australia and lead author of the paper.
Hurricane Ian: When the power grid goes out, could solar and batteries power your home?
Hurricane Ian's catastrophic winds and flooding are likely to bring long-lasting power outages to large parts of Florida. The storm is the latest in a line of hurricanes and extreme heat and cold events that have knocked out power to millions of Americans in recent years for days at a time.
