A Star is Born: Dark-Hued Nebula

The region lies near the southern end of Taurus located on the border of the constellations of Taurus and Perseus more than 400 light-years away. 

A light-year is the distance light travels in one year, or about 6 trillion miles (10 trillion kilometers).

This photo shows the cosmic region known as Sh2-239 and LDN 155, where star formation activity has caused the mix of dust and colors in the nebulas visible here.

The deep colours and dark clouds in this image resemble paintings by some of history's greatest artists.

Astrophotographer Adam Block of the Mt. Lemmon SkyCenter at the University of Arizona was one of the first to capture the nebula in such detail.

He took multiple exposures to collect enough light for an image that would otherwise not be evident to the eye.

"Sh2-239 is my favourite object, because although it is a well-studied nebula, not even professional astronomers have seen it in such detail and in the visible light." Block wrote in an email.

The region lies near the southern end of the constellation Taurus, near the border of the constellation Perseus, more than 400 light-years away.

A light-year is the distance light travels in one year, or about 6 trillion miles (10 trillion kilometers).

The region is often photographed by skywatchers and consists of bright red emission nebulas, star clusters, complex dark nebulas and blue reflected light. The spot is known as a birthplace for stars.

A star develops from a giant, slowly rotating cloud that is made up almost entirely of hydrogen and helium. The process creates new stars and releases cosmic dust and gas.

Ukraine Postpones Delivery Of Taurus-II Launch Vehicle's First Stage To US


Ukraine's state owned company "Yuzhmash" based in eastern city Dnipropetrovsk postponed the delivery of the basic part of the Taurus-II launch vehicle's first stage to a U.S. company, the Ukranian company said in a statement on Tuesday.

"For some technical reasons, the delivery date has been put off to September-October," the statement said.

The delivery was reportedly scheduled for August.

The two-stage launch vehicle is designed to transport loads of up to five tons into low orbit.

In 2008, Ukraine's companies "Yuzhnoye" and "Yuzhmash" signed a long-term contract with U.S. Orbital Sciences Corp. on cooperation in producing Taurus-II rocket till 2019.

According to the document the Ukrainian side is responsible for designing and producing the first stage of the launch vehicle, the U.S. side for the second stage, ground complex and assembly.

The Taurus-II program is funded by NASA.
