Don’t get your hopes up – scientists aren’t making Pluto a planet again just yet. But the number of possible planets that we haven’t discovered was recently bumped up to two. Last fall researchers published a study on the mysterious Planet Nine , which could explain the unusual tilt of the sun. Now University of Arizona (UA) scientists think they may have found evidence for yet another planetary mass object – and it could be closer than Planet Nine. Planet Nine – which scientists think might be 10 times Earth’s mass – could be lurking out past Pluto’s orbit. But Planet Nine might not be all we’ve missed in our solar system . Kat Volk and Renu Malhotra of the Lunar and Planetary Laboratory at UA think they’ve found an unknown planet that’s between the mass of Earth and Mars. What gave this potential planet away was the fact it could be controlling the orbital planes of Kuiper Belt objects (KBOs) – a group of space rocks.

Instead, they’re tilted away by around eight degrees, suggesting a mysterious something might be warping their orbital planes. Volk, lead author on a study slated for publication in the Astronomical Journal , said in a statement, “The most likely explanation for our results is that there is some unseen mass. According to our calculations, something as massive as Mars would be needed to cause the warp that we measured.” Why haven’t we yet stumbled across this potentially rather large planet? Volk and Malhotra say we haven’t searched the whole sky for distant objects in the solar system – Planet 10 may have been hiding among the densely packed galactic plane. We might catch a glimpse of Planet 10 when the construction of the Large Synoptic Survey Telescope – an instrument operated by a consortium including UA – is completed, possibly in 2020.

Comments Off on Solar-powered Cloverdale house is made of reclaimed wood from a 1970s kit home

This solar-powered home in Cloverdale, California was built using reclaimed wood from an existing 1970s kit log home. Turnbull Griffin Haesloop Architects utilized existing site elements to create the new 2150-square-foot house with minimal impact on the environment. The owners of the property commissioned the architects to design a sustainable home that’s easy to use and doesn’t disrupt its natural surroundings. Inspired by traditional screened porches , the architects designed a screened-in living space and included the porch in the body of the house as an entry to the guest bedrooms. This double role of the porch reduced the need for circulation and helped keep the footprint of the house to it minimum .

PV-powered heat pumps provide radiant heating or cooling, depending on the weather conditions and seasonal needs. In order to reduce construction costs, the architects reused the wood of the original kit log house as decking, interior and exterior wood paneling. + Turnbull Griffin Haesloop Architects Via Dwell Photos by Matthew Millman

Astrophysicists have long wondered why our sun is tilted at a different angle than the rest of the known solar system . While all eight known planets rotate on a flat plane within only a few degrees of one another, the sun itself appears to be tilted roughly six degrees off of the planets. Now, new research shows that a massive, undiscovered ninth planet at the edge of the solar system might actually be causing the other planets to “wobble” in their orbit around the sun. https://www.youtube.com/watch?v=h72tABvkLAo This isn’t the first time scientists have speculated about the existence of “Planet Nine” – earlier this year researchers from Caltech predicted its existence due to the abnormal bunching of several objects orbiting near Neptune, an effect which could only exist if a large, unknown planet were exerting a gravitational influence. Planet Nine has yet to be observed directly, but more and more evidence is beginning to point to its existence as the answer to some of our solar system’s enduring mysteries. Related: Astronomers may have discovered a ninth planet in our solar system If you’ve never heard about the fact that the planets are slightly off-kilter compared to the sun, you’re not alone. Mike Brown, one of the authors behind the Planet Nine theory, explains, “It’s such a deep-rooted mystery and so difficult to explain that people just don’t talk about it.” The as-yet unseen planet is estimated to be about 10 times the size of Earth, with an orbit 20 times farther from the sun than Neptune . It also appears to orbit about 30 degrees off of the orbital plane of the rest of the solar system – an angle that, along with its massive size, could be slowly pulling objects within the solar system off-balance. That’s not too surprising, considering scientists believe Planet Nine might eventually destabilize the solar system once the sun balloons into a red giant. Related: Mysterious ninth planet could one day tear apart the solar system What is still unknown is exactly how Planet Nine came to occupy its unusual orbit in the first place. It’s possible it may have once sat with the gas giants near Jupiter before being ejected. The gravitation pull of other stellar bodies might have also had an influence at some point in the solar system’s distant past. The new study will be published in an upcoming issue of Astrophysical Journal . Via Phys.org Images via Caltech
