    Recent studies suggest that the Moon's interior may still contain a partially molten layer, challenging previous assumptions that it had completely cooled and solidified. Using data from NASA's GRAIL and Lunar Reconnaissance Orbiter missions, researchers detected changes in the Moon's gravity, revealing a low-viscosity zone (LVZ) beneath the solid mantle.

  • Powerful Solar Flare To Trigger Auroras And Possible Communication Disruptions

    Powerful Solar Flare to Trigger Auroras and Possible Communication Disruptions
    • News
    • Astronomy
    A massive X7.1-class solar flare erupted from the sun on October 1, 2024, sending a coronal mass ejection (CME) toward Earth. The resulting geomagnetic storm could trigger auroras visible in lower latitudes than usual and may affect satellite communications and power grids. This flare is the second-most powerful of Solar Cycle 25, reflecting a period of heightened solar activity as the sun nears its solar maximum.

  • NASA’s James Webb Space Telescope’s NIRCam (Near-Infrared Camera) image of the galaxy cluster PLCK G165.7+67.0, also known as G165, on the left shows the magnifying effect a foreground cluster can have on the distant universe beyond. The foreground cluster is 3.6 billion light-years away from Earth. The zoomed region on the right shows supernova H0pe triply imaged (labeled with white dashed circles) due to gravitational lensing. In this image blue represents light at 0.9, 1.15, and 1.5 microns (F090W + F115W + F150W), green is 2.0 and 2.77 microns (F200W + F277W), and red is 3.56, 4.1, and 4.44 microns (F356W + F410M + F444W).
