Astronomers have at last uncovered newborn stars at the frenzied center of our Milky Way galaxy. The discovery was made using the infrared vision of NASA's Spitzer Space Telescope. The heart of our spiral galaxy is cluttered with stars, dust and gas, and at its very center, a supermassive black hole. Conditions there are harsh, with fierce stellar winds, powerful shock waves and other factors that make it difficult for stars to form. Astronomers have known that stars can form in this chaotic...

The U.S. space agency says its Spitzer Space Telescope is out of the coolant used to chill its infrared instruments and has entered a warm mode of operation. After more than five years of searching the cosmos, the National Aeronautics and Space Administration says Spitzer will warm up slightly, with only two of its infrared detector arrays operating. Spitzer ran out of its liquid helium coolant at 6:11 p.m. EDT Friday. Scientists and engineers will spend the next few weeks recalibrating the...

Scientists have long wondered how tiny silicate crystals, which need sizzling high temperatures to form, have found their way into frozen comets, born in the deep freeze of the solar system's outer edges. The crystals would have begun as non-crystallized silicate particles, part of the mix of gas and dust from which the solar system developed. A team of astronomers believes they have found a new explanation for both where and how these crystals may have been created, by using NASA's Spitzer...

The primary mission of NASA's Spitzer Space Telescope is about to end after more than five and a half years of probing the cosmos with its keen infrared eye. Within about a week of May 12, the telescope is expected to run out of the liquid helium needed to chill some of its instruments to operating temperatures. The end of the coolant will begin a new era for Spitzer. The telescope will start its "warm" mission with two channels of one instrument still working at full capacity. Some of the...

The U.S. space agency says its Spitzer Space Telescope is about to use the last of the coolant that has chilled it for the past 5 1/2 years. The National Aeronautics and Space Administration observatory is predicted to run out of the liquid helium that has kept its infrared detectors at prime operating temperatures of just a few degrees above absolute zero. The helium is expected to be exhausted this month. The spacecraft is in orbit around the sun more than 62 million miles behind Earth....

NASA's Spitzer Space Telescope is about to use its last drop of the coolant that has chilled it for the past five-and-a-half years. On about May 12, give or take a week or so, the observatory is predicted to run out of the liquid helium that has run through its veins, keeping its infrared detectors at frosty operating temperatures of just a few degrees above the coldest temperature possible, called absolute zero. The spacecraft, which is now in orbit around the sun more than 100-million...

An extremely deep Chandra X-ray Observatory image of a region near the center of our galaxy has resolved a long-standing mystery about an X-ray glow along the plane of the galaxy. The glow in the region covered by the Chandra image was discovered to be caused by hundreds of point-like X-ray sources, implying that the glow along the plane of the galaxy is due to millions of such sources. This image shows an infrared view from the Spitzer Space Telescope of the central region of the Milky Way,...

NASA's Galaxy Evolution Explorer Mission marks its sixth anniversary studying galaxies beyond our Milky Way through its sensitive ultraviolet telescope, the only such far-ultraviolet detector in space. The mission studies the shape, brightness, size and distance of galaxies across 10 billion years of cosmic history, giving scientists a wealth of data to help us better understand the origins of the universe. One such object is pictured here, the galaxy NGC598, more commonly known as M33. In...

A team of astronomers from the Instituto Astrofisica Canarias (IAC) have found an interesting shadow cast by a forming star system. Team member Dr Basmah Riaz, an ER fellow for the Marie Curie CONSTELLATION network, will present the results of their work on Thursday 23rd April in a poster at the European Week of Astronomy and Space Science conference at the University of Hertfordshire. In March 2008 the scientists observed the young star (protostar) system 2M171123 in the B59 molecular cloud,...

omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
