Sunspots are cool areas caused by strong surface magnetic fields that inhibit convection. Moreover, strong magnetic fields can alter the average atmospheric structure, degrading our ability to measure stellar masses and ages. Stars that are more active than the Sun have more and stronger dark spots than does the Sun, including on the rotational pole. Doppler imaging, which has so far produced the most...

No Sun-like dynamo on the active star ζ Andromedae from starspot asymmetry
Sunspots are cool areas caused by strong surface magnetic fields that inhibit convection. Moreover, strong magnetic fields can alter the average atmospheric structure, degrading our ability to measure stellar masses and ages. Stars that are more active than the Sun have more and stronger dark spots than does the Sun, including on the rotational pole. Doppler imaging, which has so far produced the most...
‘Death Star Viaduct’ shows Luke Skywalker delivering fatal blast to Seattle’s waterfront roadway
A new drone video wowed us a couple days ago because it was shot inside Seattle’s under-construction SR 99 tunnel. But an altered version on Youtube that includes “Star Wars” footage and Luke Skywalker blowing up the Alaskan Way Viaduct may just win the week.
“Death Star Viaduct” mashes the climatic scene from the original “Star Wars” film with footage of Seattle’s waterfront as well as scenes captured...
Temperate Earth-sized planets transiting a nearby ultracool dwarf star
Star-like objects with effective temperatures of less than 2,700 kelvin are referred to as ‘ultracool dwarfs’. This heterogeneous group includes stars of extremely low mass as well as brown dwarfs (substellar objects not massive enough to sustain hydrogen fusion), and represents about 15 per cent of the population of astronomical objects near the Sun. Core-accretion theory predicts that, given the small masses of these ultracool...
