The Brightest of Stars

The Brightest of Stars

Swirls of gas and dust reside in this ethereal-looking region of star formation seen by NASA's Hubble Space Telescope. This majestic view, located in the Large Magellanic Cloud (LMC), reveals a region where low-mass, infant stars and their much more massive stellar neighbors reside. A shroud of blue haze gently lingers amid the stars.

Known as LH 95, this is just one of the hundreds of star-forming systems, called associations, located in the LMC some 160,000 light-years distant. Earlier ground-based observations of such systems had only allowed astronomers to study the bright blue giant stars present in these regions. With Hubble's resolution, the low-mass stars can now be analyzed, which will allow for a more accurate calculation of their ages and masses.

The U.S. Navy's test of Vanguard rocket, along with its satellite payload, went hopelessly awry when the rocket failed to develop sufficient thrust and toppled over on the launch pad. The malfunctioning first stage caused vehicle to lose thrust after two seconds.

The Dec. 6, 1957 launch was slated for the U.S. International Geophysical Year program to place satellite in Earth orbit to determine atmospheric density and conduct geodetic measurements.

Self-Portrait

Rick Mastracchio, STS-118 mission specialist, uses a digital camera to expose a photo of his helmet visor during the mission's first planned session of extravehicular activity (EVA) as construction continues on the International Space Station. Also visible in the reflection are components of the station and the docked shuttle.
