The Elephant’s Trunk nebula, formally known as IC1396A, is a cloud of gas and dust located 2400 light years from Earth in the constellation Cepheus. The Elephant Trunk is part of a larger region of ionized gas illuminated by a nearby massive O-type star (located outside the image to the left). Radiation and winds from this hot star compress and ionize the edges of cloud, resulting in the bright “ionization fronts” seen in this image.
Young stars at very different stages of formation have been found both within and just outside the Elephant’s Trunk. Very young protostars, still accreting material from the surrounding nebula, are located inside the cloud, while fully formed stars have been found just in front of the ionization edges. This suggests that star formation has been proceeding sequentially through the cloud as a result of the ‘triggering’ effects of the hot star (Barentsen, 2011). On the order of 5% of the mass of gas and dust in the cloud has already been turned into protostars (Reach, 2004), and the process is continuing today.

The bright summer Milky Way from Scorpius to Sagittarius and Aquila appear over rocks and sand pipe formations of Kodachrome Basin State Park in Utah, USA.
Also notable in the sky are banded green patches which are airglow; natural emission of the Earth upper atmosphere which is generally faint in the visible lights.

Astronomers using the Hubble Space Telescope have found another moon circling Neptune, a giant planet located about 30 times farther away from the sun than Earth. The new moon was too small to be noticed by Voyager 2′s cameras when it completed its flyby of the planet in 1989. Read more
