Space eye candy: Cool cosmic dust and a bright Orion nebula

eso1321a

This patch of sky holds some of the youngest stars ever found. The ribbon that runs through the centre of the image is made up of dust clouds in the constellation Orion, which holds one of the busiest nearby stellar nurseries. The composite image includes both infrared light at wavelengths too long for the human [...]

Crushed comets give star a dusty belt

Two thousand comets a day collide around nearby star Fomalhaut creating a continually replenished dust belt in the outskirts of the star’s system, according to a new paper recently published in the journal Astronomy & Astrophysics. Fomalhaut is a young star. It is twice as massive as the sun and sits 25 light years away [...]
