the impressive image offered by the Hubble telescope

Hubble continues to leave spectacular images. This space telescope orbits outside Earth’s atmosphere, in a circular orbit around planet Earth at 593 kilometers above sea level. It is a collaborative project between NASA and the European Space Agency (ESA) that inaugurated the Great Observatories programme.

One of the latest and striking images that he has provided us is a portion of the open cluster NGC 6530. This appears as a wall of smoke dotted with stars, but it is a collection of several thousand stars located about 4,350 light years from Earth in the constellation Sagittarius.

The cluster lies within the larger Lagoon Nebula, a gigantic interstellar cloud of gas and dust. It is the nebula that gives this image its distinctly smoky appearance; Clouds of interstellar gas and dust stretch across the image.

The astronomers investigated NGC 6530 using Hubble’s Advanced Camera for Surveys and Wide Field Planetary Camera 2. They toured the region hoping to find new examples of proplids, a particular class of illuminated protoplanetary disks that surround newborn stars. The vast majority of known proplids are found in a single region, the nearby Orion Nebula. This makes understanding its origin and lifetime in other astronomical settings challenging.

Hubble’s ability to observe at near-infrared wavelengths, particularly with the Wide Field Camera 3, has made it an indispensable tool for understand the birth of a stars and the origin of exoplanetary systems, reports NASA.

The unprecedented observing capabilities of the new NASA/ESA/CSA James Webb Space Telescope at infrared wavelengths will complement Hubble observations by allowing astronomers to look through the dusty wrappers around newborn stars and investigate the earliest and faintest stages of stellar birth.
