We can't touch the deep interior of our planet, but we can now see it in the "light" of neutrinos emitted by radioactive elements. Early results suggest our Earth is intriguingly lopsided. 🧪 www.quantamagazine.org/neutrinos-fr...
Lateral variation of mantle geoneutrino signal predicted for a “thermochemical piles” model. Early results seem to confirm this model.

Altair is a nearby A-type star. It is also one of the hottest nearby stars with X-ray emission, probably arising from corona around its equatorial regions, where convective envelope which sustain them persist on this highly oblate star. #art #astronomy #space #spaceart #star #Altair
This artwork depicts a fictional view of Altair's corona seen with SDO AIA camera's 171 Å channel, accompanied by some information.

At the centre is the star; the photosphere is entirely dark, and the corona can be seen as a faint band ringing the star's equator and intermediate latitudes, while the visible pole is dark. The corona is depicted as slightly heterogenous, with dark patches and bright spots scattered across it.

At top left is basic information about Altair (α Aql): mass of 1.86 ± 0.03 Solar masses, radii of 2.008 ± 0.006 Solar radii (equator) / 1.565 ± 0.014 Solar radii (pole), effective temperature of 6780 K (equator) / 8621 K (pole), and rotation period of 7.79 hours.

Top right contains my summary of Altair's coronal properties obtained from Robrade & Schmitt (2009). The coronal surface flux is comparable to solar background corona, the plasma temperature is similar to low activity stars like the Sun and is dominated by quiescent/weakly active regions and open magnetic fields with weak contributions from moderately active regions, and that the coronal structures are small (few %) relative to the star. Altair's X-ray flux varies, arising from both rotational modulation, as well as intrinsic variabilities, eg. emergence and decay of active regions. Flares are not detected, as expected.Same as previous image, although Altair's limb and equator are outlined as solid line and dashed line, respectively.

SwRI-led modeling identifies new scenarios for Moon formation ow.ly/vsjv50ZHN9P
Visualization of planetary bodies showing temperature distribution and gravitational strength with color-coded scales and distance markers.

New Southwest Research Institute-led modeling that accounts for material strength found fundamental changes in how the Moon forms after a giant collision between a Mars-sized impactor and Earth. Simulations that neglect strength (top) produce a debris disk that forms the  Moon over time while those factoring in strength (bottom) can produce an intact Moon. These conditions generally correspond with hotter (top) and colder (bottom) colliding planets, which would generally correspond to earlier versus later collision timing. These conditions could also affect the composition of the Moon and the Earth, which remains an open question in the scientific community.
