Latest Orion Nebula Stories
A new Rice University-led survey of one of the most active star-forming regions in the galactic neighborhood is helping astronomers better understand the processes that may have contributed to the formation of the sun 4.5 billion years ago. The survey of Carina Nebula is available online in the Astronomical Journal.
Current theories suggest that rocky planets like Earth start their lives as microscopic bits of dust tinier than a grain of sand. However, astronomers have recently discovered that filaments of star-forming gas near the Orion Nebula might be full of pebble-sized particles.
Observations of a Sun-like star through the Herschel Space observatory may have unlocked the mystery of meteorites in our own galaxy, according to European Space Agency (ESA) astronomers.
Stars that are just beginning to coalesce out of cool swaths of dust and gas are showcased in this image from NASA's Spitzer Space Telescope and the Two Micron All Sky Survey (2MASS).
Astronomers have found cosmic clumps so dark, dense and dusty that they throw the deepest shadows ever recorded.
Astronomers have studied two star clusters using NASA's Chandra X-ray Observatory and infrared telescopes and the results show that the simplest ideas for the birth of these clusters cannot work
The prevailing theory on star cluster formation states that gravity causes a giant cloud of gas and dust to condense to concentrations that trigger the ignition of stars at the center of the cloud.
WASHINGTON, May 7, 2014 /PRNewswire-USNewswire/ -- Using data from NASA's Chandra X-ray Observatory and infrared telescopes, astronomers have made an important advance in the understanding of
To celebrate its 24th year in orbit, the NASA/ESA Hubble Space Telescope has released a beautiful new image of part of NGC 2174, also known as the Monkey Head Nebula.
WASHINGTON, March 17, 2014 /PRNewswire-USNewswire/ -- In celebration of the 24th anniversary of the launch of NASA's Hubble Space Telescope, astronomers have captured infrared-light images of
Planetary Nebula -- A planetary nebula is an astronomical object that usually appears nebulous and disk-like in low-resolution observations. Because of this appearance, similar to the appearance of planets in early observations, the "planetary" adjective was attached and has since been retained for historical consistency. According to current observations and models, planetary nebulae in fact have little to do with planets. Instead, as a small star (less than a few times the mass...
Saturn Nebula -- The layers of the Saturn Nebula give a complex picture of how this planetary nebula was created. The above picture, taken in April 1996 and released last week, allows a better understanding of the mysterious process that transformed a low-mass star into a white dwarf star. A computer model indicates that the central star of NGC 7009 first expelled the green gas that now appears barrel shaped. This green gas now confines stellar winds flowing from the central star,...
Owl Nebula -- Dicovered by Pierre Mchain in 1781. The Owl Nebula M97 is one of the fainter objects in Messier's catalog, discovered by Pierre Mchain on February 16, 1781. In his description of this object, Charles Messier also mentions two other nebulous objects that he (and Mchain) have seen at about the same time, but which he had not added in his printed catalog version of 1781 (in the Connaissance des Temps for 1784). As the description is obvious and he added positions by...
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...
Hubble's Variable Nebula -- Hubble's variable nebula is named (like the Hubble telescope itself) after the American astronomer Edwin P. Hubble, who carried out some of the early studies of this object. It is a fan-shaped cloud of gas and dust which is illuminated by R Monocerotis (R Mon), the bright star at the bottom end of the nebula. Dense condensations of dust near the star cast shadows out into the nebula, and as they move the illumination changes, giving rise to the variations first...
