O panorama espetacular mostra as imediações da estrela Wolf-Rayet, WR 22, na nebulosa de Carina (dir.) e da estrela Eta Carinae (esq.). A imagem também foi composta a partir de La Silla, no Chile. Foto: ESO

This panoramic view combines a new image of the field around the Wolf–Rayet star WR 22 in the Carina Nebula (right) with an earlier picture of the region around the unique star Eta Carinae in the heart of the nebula (left).

A closer look at Orion

A closer look at Orion

The constellation of Orion holds much more than three stars in a row. A deep exposure shows everything from dark nebula to star clusters, all embedded in an extended patch of gaseous wisps in the greater Orion Molecular Cloud Complex.

RCW 38. It is a young star cluster found slightly less than 6,000 light-years away in the constellation Vela. Home to many young, rapidly evolving stars, it is a great place for astronomers to study stellar evolution. Some of these young giants will one day explode as supernovas, seeding the area with material for the next generation of stars.

The California Nebula (also known as NGC 1499.The bright blue star Menkib (to the right of the nebula) most likely is the source of illumination for the nebula.  It is visually 12,700 times brighter than the Sun with absolute magnitude -5.5. If we include the ultraviolet light that emanates from Menkib its total, bolometric, luminosity is 263,000 times that of the Sun. is 30 solar masses and a surface temperature of 35,000 k, making it one of the hottest stars that can be seen with the eye.

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.
