Hot blue starIts story
Lambda Canis Majoris burns with B-type blue light some 424 light-years away, in a constellation that chases Orion across the winter sky. A few degrees from Sirius —the brightest star visible from Earth— its glow is eclipsed by sheer proximity. It is an example of how the sky's geometry can make modest what would, elsewhere, be a lead.
