A positive-polarity coronal hole is approaching the center of the Earth-facing disk. This is the correct polarity for the Russell-McPherron effect for this time of the year, so more south Bz and enhanced geomagnetic effects could be possible from this feature, but we will see!

"The heel toe walk with eyes open was doable, but definitely off my balance game once they had me repeat with eyes closed (shown here). Exponentially better performance even just the next day, such an interesting recovery process! Stay tuned for the week’s recap of science and rehabilitation."

After five years on Mars, Perseverance has traveled almost 25 miles (40 km), and the mission team has been busy testing the rover’s durability and gathering new science findings on the way to a new region nicknamed “Lac de Charmes,” where it will be searching for rocks to sample in the coming year.

This infographic illustrates the distances driven by various rovers on the surface of Earth’s Moon and Mars. Of the vehicles shown, the NASA Mars rovers Perseverance and Curiosity are still operational and moving across the surface; the figures shown for those two are distances driven as of Oct. 11, 2026.

AR 4551 is slowly rotating towards the central meridian. It remains mostly unchanged, a beta region with a decent area (360 MSH). The flare potential remains relatively low, with the SWPC estimating a 15% chance of M-class flares. Jure Atanackov x.com/JAtanackov/s...

For more than a quarter century, unidentified chemical signatures from a white dwarf star have laid dormant in the archive of the NASA/ESA Hubble Space Telescope, until diligent sleuthing by a young astronomer revealed something extraordinary:
White Dwarf HS 0209+0832 over Time (artist’s concept)

In this (not-to-scale) artist’s concept, a lower-mass star like the Sun (1) ages into a puffy red giant star (2) that eventually expels its outer envelope of gas and dust into space, which forms a disk around the bright cinder of its remaining core, called a white dwarf (3). A second-generation planet forms in this disk, orbiting the white dwarf and losing some of its atmosphere back onto the white dwarf’s surface (4).
