Earth formed over 4.5 billion years ago via accretion . Earth’s building blocks were chunks of rock of varying sizes. From dust to planetesimals and everything in between.
But some evidence doesn’t line up well behind that conclusion. A new study says that some of the Earth-forming meteorites came from much further out in the Solar System.
The Solar System is Getting High-Speed Internet
Aquarian Space, the world's first high data rate internet service for the Solar System, announced today they have successfully raised a seed round led by notable Draper Associates, a leader in early-stage venture capital having funded companies such as SpaceX, Tesla and Coinbase.
Aquarian Space is solving this problem by setting up communications between Earth, the Moon, Mars and beyond by building commercial high data rate, high-speed delivery satellite networks enabling 100Mbps Moon to Earth speeds 24/7.
Surprise! We Still Haven't Found Planet Nine
Although the hypothetical object continues to evade detection, a six-year search in millimeter wavelengths has allowed astronomers to rule out an object with Planet Nine's predicted properties in a large swathe of the southern sky.
The search also yielded some candidate objects that might be interesting to follow up in future surveys.
Federal Solar Tax Credit Guide (2022)
Since 2005, the federal government has incentivized homeowners to switch to solar through the solar investment tax credit (ITC), also known as the federal solar tax credit.
To help you take advantage of this perk while it lasts, we at the Home Media reviews team have conducted in-depth research and analysis on the best solar companies in the United States.
High Rare Earth Element Concentrations in Rare Meteoritic Sulfides May Represent New Residual ...
Enstatite chondrites (ECs) are a very reduced (oxygen-poor) type of primitive meteorite in which elements like Fe and S are present mainly as metal and sulfides rather than oxides and sulfates.
A new study of ECs by Tahar Hammouda, Maud Boyet, and Paul Frossard (CNRS, IRD, OPGC, Laboratoire Magmas et Volcans, Université Clermont Auvergne) and Camille Cartier (Université de Lorraine) describes an interesting message from oldhamite (CaS), an unusual mineral found in ECs.
UA to help lead HelioSwarm mission to study solar wind | KJZZ
The superheated matter called plasma makes up most of the visible universe, from stars to nebulas to the northern lights.
Later this decade, the University of Arizona will help lead a mission to study plasma in and around the Earth.
"We're exploring this fundamental process and really, we're only able to do it here in the solar wind," said deputy principal investigator Kristopher Klein, an assistant professor of planetary sciences in UA's Lunar and Planetary Laboratory.
Rivers run through this geomorphologist's research on Earth and beyond | PBS NewsHour
To geomorphologist Taylor Perron, the answers to some of the biggest questions about our solar system are found in the way a landscape changes over time.
Studying a range of topics that at first glance might appear unrelated – from the terrain of Mars to human prehistory – Perron's research group at the Massachusetts Institute of Technology uses landscape to glean clues about the past and future.
LETTER: It's not fair to ask me to pay for your solar panel hobby
For starters, the notion that the rooftop solar industry is dominated by small mom-and-pop businesses does not pass the red face test. Each rooftop installation involves financing about $40,000 for the homeowner. There are already hundreds of installations.
Net metering, the focus of the current argument, is a huge win for the solar companies and a loss for those not jumping on the band wagon. Subsidies through tax credits and transfer of costs to ratepayers without solar systems is the only reason a rooftop solar system makes sense economically.
Lightsail technology billows into the future | Astronomy.com
Lightsails were once a thing of science fiction, evolving through several variations over the last 40 years. Now, science fiction is becoming reality.
Researchers from UCLA and the University of Pennsylvania recently published two papers outlining various shapes and heat-dissipating materials they tested to evaluate lightsails beyond previous limits.
