Fr.: couronne E
A part of the → solar corona defined by the → emission lines of hot gases. These emission lines include the so-called → forbidden lines of the strongly ionized atoms of iron, calcium, and other elements. The E corona is thinner than the → K corona and the → F corona (M.S.: SDE).
Fr.: anneau E
The world's largest → optical and
→ near infrared
telescope, with a diameter of 42 m, to be built by the
→ European Southern Observatory (ESO).
→ First light is foreseen for 2018. The

Eagle Nebula (IC 4703)
Fr.: Nébuleuse de l'Aigle
A prominent → H II region in the constellation → Serpens lying about 2 kpc away from the Sun. It measures about 30' across and surrounds the open cluster → M16 (NGC 6611), which contains at least 20 stars of spectral type B0.5 or earlier, including one 05V. At a projected distance from the cluster of about 2 pc, where the H II region has expanded into surrounding → molecular cloud, a striking → elephant trunk morphology or → pillar results. The nebula is the site of ongoing → star formation, especially in these pillar structures. The Eagle Nebula is often erroneously given the cluster's designation (M16).
