Zeta Ophiuchus, a massive star plowing through the gas and dust floating in space. Zeta Oph is a bruiser, with 20 times the Sun’s mass. It’s an incredibly luminous star, blasting out light at a rate 80,000 times higher than the Sun! Even at its distance of 400 light years or so, it should be one of the brightest stars in the sky … yet it actually appears relatively dim to the eye.

Une image spectaculaire Hubble Space Telescope révèle le cœur de la nébuleuse de la Lagune.  Considéré comme un nuage massif de poussière et de gaz incandescents, bombardé par le rayonnement énergétique de nouvelles étoiles, ce nom placide cache une réalité dramatique.

This Hubble image shows RS Puppis, a type of variable star known as a Cepheid variable. RS Puppis is unusual; this variable star is shrouded by thick, dark clouds of dust enabling a phenomenon known as a "light echo" to be shown with stunning clarity. These Hubble observations show the ethereal object embedded in its dusty environment, set against a dark sky filled with background galaxies.
