Typical grant sucking exaggerated theories
Stating this all is fact is totally laughable. I enjoy learning about real science findings, but presently, it is all they can do to even determine that maybe there is a planet around a star other than our own by its wobble. Composition of distant objects is only theoretical, even less their gravitational levels. They have no way whatsoever of accurately determining what they are actually made of on their surface (only reflected light wavelengths, which are far from the final word and very crude, they are only a preliminary tool to start from) even less what the supposed planet's core is made of, which is invisible to their instruments, which would affect gravity levels tremendously. As the composition of atmosphere is entirely uncertain as well, temperature levels of this all but invisible "planet" is truly impossible. But all theories are welcome to be reported as fact! After all, no one has the ability to refute them since we can not even get past 2/3 of our own solar system with a lander probe! We are even somewhat in the dark as to the full nature of the composition of our own planets core is, being unable to extract any matter that deep to study hands-on. Even that is theoretical, although the theories are founded on much more study and physical data and may be correct... or not.
Those beautiful multi colored photos of nebulas from Hubble you have seen... were not taken in color, but via time exposed infrared black and white and then colorized after the fact. Additionally, the color is artificially enhanced and often significantly inaccurate even according to what they know the general color to be in some cases. Sometimes with known-red nebulas, they multi color them to make them look prettier. All to stimulate interest - for popular...and financial grant attraction reasons, I suppose. But accurate they aren't - nor is it scientifically accurate to present them as how they really look like at least color-wise. The trend is all too common.
Inferring that the technology exists to determine the makeup, gravity, atmosphere, and temperature of a distant all-but-invisible planet is just like the 5 minute DNA tests on CSI - the technology doesn't exist and therefore the results are fabricated as well. Why they cannot stick to what is known within our technological capabilities (which is often exciting of itself, although not as flashy) and mark theories beyond that as what they are is troubling. But perhaps telling people that they have noticed a wobble in a distant star and that there seems at time to be a blue wavelength light cropping up which might mean a planet that has water, doesn't grab grant funding the same way. Why they don't go all the way and tell us its likely that it is similar to the planet in Avatar, making a pop culture link, I don't understand.
But the vegetable pressure cooker promotional idea might win some interest with the low-carb crowd. That does mean that the planet is likely inhabited entirely by healthy aliens with low cholesterol levels, doesn't it? Perhaps they should add that to the report.
