Stars in our galaxy may often pump out waves of million-degree gas that make surrounding nebulas glow with x-rays. These new findings could shed light into how planetary systems form—including our own solar system, researchers said. Astrophysicists focused on the Orion Nebula, a cloud of dense and turbulent gas visible to the naked eye in the night sky, right below the belt of the constellation Orion. Four extremely bright and massive stars, called the Trapezium,...

Right in time for the festive season, ESA's XMM-Newton X-ray observatory has discovered a huge cloud of high-temperature gas resting in a spectacular nearby star-forming region, shaped somewhat like the silhouette of Santa Claus. An early present for astronomers, the cloud suggests that hot gas from many star-forming regions leaks into the interstellar medium. The Orion nebula is the nearest dense star-forming region to Earth that contains stars much more massive than the Sun. XMM-Newton's...

Astronomers have long scrutinized the vast and layered clouds of the Orion nebula, an industrious star-making factory visible to the naked eye in the sword of the famous hunter constellation. Yet, Orion is still full of secrets. A new image from NASA's Spitzer Space Telescope probes deep into the clouds of dust that permeate the nebula and its surrounding regions. The striking false-color picture shows pinkish swirls of dust speckled with stars, some of which are orbited by disks of...

NASA -- In one of the most detailed astronomical images ever produced, NASA's Hubble Space Telescope captured an unprecedented look at the Orion Nebula. This turbulent star formation region is one of astronomy's most dramatic and photogenic celestial objects. "Orion is a bustling cauldron of activity. This new large-scale Hubble image of the region reveals a treasure-house of beauty and astonishing detail for comprehensive scientific study," said Jennifer Wiseman, NASA's Hubble program...

Vanderbilt -- For the past few months, Bob O'Dell has been mapping the winds blowing in the Orion Nebula, the closest stellar nursery similar to the one in which the sun was born. New data from the Hubble Orion Heritage Program, a major observational effort by the Hubble Space Telescope in 2004 and 2005, have given the Vanderbilt astronomer the information he needs to measure the stellar winds with unprecedented detail, and he reported his early results on Jan. 11 at the annual meeting of the...

WASHINGTON, D. C. -- New observations of the Orion Nebula at infrared wavelengths reveal that small dust grains located in disks around young stars are growing, taking the initial steps toward forming planets despite bathing in a flood of radiation from highly luminous stars. The properties of dust in disks around young stars plays a pivotal role in understanding star formation and determining the origins of planets in our Solar system and in extrasolar planetary systems as well. The results...

Cambridge, MA -- Meeting this week in Cambridge, Mass., astronomers using the Submillimeter Array (SMA) on Mauna Kea, Hawaii, confirmed, for the first time, that many of the objects termed "proplyds" found in the Orion Nebula do have sufficient material to form new planetary systems like our own. "The SMA is the only telescope that can measure the dust within the Orion proplyds, and thereby assess their true potential for forming planets. This is critical in our understanding of how solar...

Orion Nebula -- Discovered 1610 by Nicholas-Claude Fabri de Peiresc. Located at a distance of about 1,600 (or perhaps 1,500) light years, the Orion Nebula is the brightest diffuse nebula in the sky, visible to the naked eye, and rewarding in telescopes of every size, from the smallest glasses to the greatest Earth-bound observatories and the Hubble Space Telescope. It is the main part of a much larger cloud of gas and dust which extends over 10 degrees well over half the constellation...

Cone Nebula -- The Cone Nebula is a famous nebula in the Orion Arm surrounding the NGC 2264 star cluster. The 'cone' is a triangular dark nebula near the bottom of the nebula. The bright star at the centre of this picture is 15 Monocerotis (or 'S Monocerotis') - it is a quadruple star system consisting of four brilliant blue-white stars (classes O7, B7, B8 and A6) and it is partly responsible for causing the nebula to glow. The distance to the Cone Nebula is well-known, because it has...
