She was originally built as the merchant ship SS Hawaiian Packer before her requisition by the U.S. Navy in 1941. Before conversion to a repair ships, Delta briefly served as a U.S. Navy cargo ship .
Delta Aquilae, Latinized from δ Aquilae, is a binary star system in the equatorial constellation of Aquila. It has an apparent visual magnitude of 3.4 [2] and, based upon parallax measurements, is located at a distance of about 50.6 light-years (15.5 parsecs) from Earth. [1] It is drifting closer with a radial velocity of −30 km/s. [6]
t. e. In mathematical analysis, the Dirac delta function (or δ distribution ), also known as the unit impulse, [1] is a generalized function on the real numbers, whose value is zero everywhere except at zero, and whose integral over the entire real line is equal to one. [2] [3] [4] Since there is no function having this property, modelling the ...
Delta Cephei (δ Cep, δ Cephei) is a quadruple star system located approximately 887 light-years away in the northern constellation of Cepheus, the King. At this distance, the visual magnitude of the star is diminished by 0.23 as a result of extinction caused by gas and dust along the line of sight. [5]

Delta Crateris (δ Crt, δ Crateris) is a solitary [8] star in the southern constellation of Crater. With an apparent visual magnitude of 3.56, [2] it is the brightest star [9] in this rather dim constellation. It has an annual parallax shift of 17.017 mas as measured from Earth, [1] indicating Delta Crateris lies at a distance of 192 ly from ...
The Nile Delta at night as seen from the ISS in October 2010. The Nile Delta ( Arabic: دلتا النيل, Delta an-Nīl or simply الدلتا, ad-Delta) is the delta formed in Lower Egypt where the Nile River spreads out and drains into the Mediterranean Sea. [1] It is one of the world's larger deltas—from Alexandria in the west to Port ...
