Very Large Telescope Reveals Low-Mass Bodies in Orion Nebula

Facebook X LinkedIn Email
The HAWK-I IR instrument on the European Southern Observatory’s (ESO) Very Large Telescope (VLT) has been used to produce the deepest and most comprehensive view of the Orion Nebula to date. The striking image reveals an abundance of faint brown dwarfs and isolated planetary-mass objects, and the presence of such low-mass bodies provides insight into the history of star formation within the nebula itself. An image of the Orion Nebula star-formation region obtained from multiple exposures using the HAWK-I IR camera on ESO's Very Large Telescope in Chile. This is the deepest view...Read full article

    astronomy
    The scientific observation of celestial radiation that has reached the vicinity of Earth, and the interpretation of these observations to determine the characteristics of the extraterrestrial bodies and phenomena that have emitted the radiation.
    infrared
    Infrared (IR) refers to the region of the electromagnetic spectrum with wavelengths longer than those of visible light, but shorter than those of microwaves. The infrared spectrum spans wavelengths roughly between 700 nanometers (nm) and 1 millimeter (mm). It is divided into three main subcategories: Near-infrared (NIR): Wavelengths from approximately 700 nm to 1.4 micrometers (µm). Near-infrared light is often used in telecommunications, as well as in various imaging and sensing...
