Using new tools, astronomers discovered a weird mismatch in surface and p-mode signals that emerged more than a decade ago and has become especially pronounced in the current epoch, Cycle 25, which began in 2019.

The Sun Is Undergoing a Mysterious Change and Nobody Knows Why

Astronomers discovered that magnetic activity in the Sun is being squeezed into a more tightly confined area under its surface, which has implications for space weather forecasts and heliophysics.

Seeing a lot of “red sun” photos that people have taken in the wildfire haze. Here’s a more benign one: it’s an “oops” photo that I snapped while attaching my phone to my telescope to capture some sunspot images a while back. I really like it though!

(But for some reason it won’t open the pod bay doors.)

An image of concentric circles. In the middle is the bright orange-yellow disc of the sun, freckled with sunspots. Around it is a red-orange glow, dimming as it reaches the rim of the telescope eyepiece. The rim itself is a thick black circle. Scattered circular afterimages and lens flares appear here and there. The sun’s appearance here strongly evokes the image of the HAL 9000 computer from the film “2001.”
