Cosmic Spotlight

Eclipse Study Tracks Solar Corona Turbulence

During the April 2024 total solar eclipse, observers caught a rare naked-eye view of the Sun’s prominences and its pearly white corona. University of Hawai’i researchers combined those high-resolution ground images with data from Sun-orbiting missions to map how turbulence moves through the corona and influences space weather. The study shows how energy cascades from large-scale structures down to smaller turbulent eddies, helping explain why the corona is millions of degrees hotter than the Sun’s visible surface. This multi-messenger approach gives scientists a more complete picture of how solar activity builds and travels outward.

Cosmic Deep Dive: How Gravity Shapes a Galaxy’s Disk

If you shrunk the Milky Way to the size of a dinner plate, its disk would be thinner than a single sheet of tissue paper — yet that fragile structure stretches 100,000 light-years across. Here’s what happens when two galaxies pass close enough for their gravity to tug on each other: stars and gas clouds get stretched and warped like taffy, creating the kind of bent disk we see in M106 today. The smaller galaxy doesn’t even need to collide; a near miss can leave lasting ripples that astronomers still detect millions of years later.

Ride along with a star on the outer edge and you’d feel the gentle pull from that distant encounter, slowly changing your orbital path by just a few kilometres per second. Over cosmic timescales those tiny shifts add up, twisting the galaxy’s flat plane into the subtle warp captured in recent images. We can measure these distortions with incredible precision, yet one big mystery remains: exactly how much of a galaxy’s dark matter halo is needed to dampen or amplify these warps.

The answer sits just beyond our current models, waiting for the next generation of telescopes to reveal it.

Spring has officially begun — clear skies and good seeing to everyone chasing the changing constellations tonight.
