List of first targets for the James Webb Space Telescope

The targets, which NASA announced yesterday were selected by an International committee of scientists from NASA, ESA, CSA and the Space Telescope Science Institute in Maryland, which manages the observatory:

• The Carina Nebula: One of the brightest nebulas -clouds of gas and dust- in the sky is about 7.6K light-years away from Earth in the southern constellation Carina, the Keel. The Carina Nebula is home to the well-known "Pillars of Destruction," long finger-like structures of cosmic gas and dust.

• WASP-96 b: A giant and extremely hot exoplanet and the first known planet with an entirely cloudless atmosphere, WASP-96 b is also the first planet scientists have spotted with such a profoundly strong sodium signature. The planet's mass is quite similar to Saturn's, leading researchers to classify the world as a "hot Saturn."

• Southern Ring Nebula: The Southern Ring or "Eight Burst" nebula, located some 2K light-years from Earth, surrounds a dying star.

• Stephan's Quintet: This compact galaxy group is located in the constellation Pegasus and consists of five galaxies, four of which are closely grouped and expected to merge with one another.

• SMACS J0723.3-7327: The James Webb Space Telescope will use the phenomenon known as gravitational lensing, in which much nearer foreground galaxies magnify and 'bend' light to obtain a deep-field view of extremely distant and faint galaxies.

The observatory recently completed calibration and testing on the third of its four scientific instruments, the Near-Infrared Spectrograph, or NIRSpec. Webb's other instruments include:

• The Near Infrared Camera (NIRCAM), the telescope's primary tool for detecting light from early stars and galaxies. The camera features a coronograph, a tool that can block out the light emanating from stars in order to see the bodies around it.

NIRCAM

• The Mid-Infrared Instrument (MIRI), a combination of a camera and a spectrograph that examines the mid-infrared part of the electromagnetic spectrum.

• The Fine Guidance Sensor/Near Infrared Imager and Slitless Spectrograph (FGS/NIRISS), a tool that can help detect distant, early light sources and identify and analyze exoplanets.
