This is a newly released Hubble image of the Lagoon Nebula, otherwise known as Messier 8 and the star cluster NGC 6523. It lies 4,500 light-years away in the constellation Sagittarius. Image credit: NASA, ESA, J. Trauger (Jet Propulson Laboratory).This new NASA/ESA Hubble Space Telescope image shows the Lagoon Nebula, an object with a deceptively tranquil name. The region is filled with intense winds from hot stars, churning funnels of gas, and energetic star formation, all embedded within an intricate haze of gas and pitch-dark dust.
A research team has used the NASA/ESA Hubble Space Telescope’s Cosmic Origins Spectrograph to study a body known as BD+44°493, the brightest known second-generation star in the sky. BD+44°493 is thought to have been enriched by elements from one of the first generation of stars and the researchers detected several elements that had never been seen before in such a star.
This image of the spiral galaxy NGC 3274 comes courtesy of the NASA/ESA Hubble Space Telescope’s Wide Field Camera 3 (WFC3). Hubble’s WFC3 vision spreads from the ultraviolet light through to the near infrared, allowing astronomers to study a wide range of targets, from nearby star formation through to galaxies in the most remote regions of the cosmos.
The placid appearance of NGC 4889 can fool the unsuspecting observer. But the elliptical galaxy, pictured here in front of hundreds of background galaxies, and deeply embedded within the Coma galaxy cluster in this new image from the NASA/ESA Hubble Space Telescope, harbours a dark secret. At its heart lurks one of the most massive black holes ever discovered.
