along with observations of dust grains change our understanding of planet formation astronomers said. Observations of the system revealed a dust trap of millimeter-size grains on one side of the star with smaller micrometer-size particles spread evenly throughout the disc.
The particles astronomers said could eventually clump into a comet factory producing kilometer-size rocks such as those found in the Kuiper Belt outside Neptune's orbit.
So far however astronomers can see only the object's effects on the system; there's no direct evidence that it physically exists.
however that has persisted among astronomers for a generation. Within the disc surrounding the star there is higher pressure closer to the star
In the case of Oph IRS 48 the astronomers think that an object with a mass 10 times that of Jupiter is forming vortices at the edge of the system creating an area of high pressure that balances out the high pressure near the star.
-and-egg problem that is bothering some astronomers: How did that massive mysterious object in Oph IRS 48 form?
but few astronomers suspected it would be so obvious in an image. To be so large that you can directly observe that is quite a surprise Armitage said.

The dust astronomers believe is a key phase in the life cycle of stars which are formed in dusty nurseries throughout the cosmos.
Now an international team of astronomers reports key observations that confirm a theory devised by University of Wisconsin-Madison astrophysicist Alexandre Lazarian and Wisconsin graduate student Thiem Hoang.
but promises a new ability for astronomers to use polarized visible and near infrared light to reliably probe the strength
research showsit might be easier than previously thought for a planet to overheat into the scorchingly uninhabitable runaway greenhouse stage according to new research by astronomers at the University of Washington and the University of Victoria published July 28 in the journal Nature Geoscience.
Revisiting this classic planetary science scenario with new computer modeling the astronomers found a lower thermal radiation threshold for the runaway greenhouse process meaning that stage may be easier to initiate than had been thought previously.
Subsequent research the astronomers say is needed in part because their computer modeling was done in a single-column clear-sky model
Still it inspired the astronomers to write As the solar constant increases with time Earth's future is analogous to Venus's past.
Astronomers use polarized light in a number of ways and there are a number of applications for polarimetry in communications and the military.

Rather than finding all of the glowing dust in a doughnut-shaped torus around the black hole as expected the astronomers find that much of it is located above and below the torus.

#Green pea galaxies could help astronomers understand early universethe rare Green pea galaxies discovered by the general public in 2007 could help confirm astronomers'understanding of reionization a pivotal stage in the evolution of the early universe
and in this case they helped the astronomers understand the relationship between the stars and gas in these galaxies.
Jaskot says the Green peas are exciting candidates to help astronomers understand a major milestone in the development of the cosmos 13 billion years ago.
#Hunt for distant planets intensifieswhen astronomers discovered planet GJ 1214b circling a star more than 47 light-years from Earth in 2009 their data presented two possibilities.
#oeit s interesting to note that all the instruments astronomers have used to study exoplanet atmospheres so far were designed never for that#Bean said.#
The discovery by astronomers at the University of California Berkeley and Clarion University in Pennsylvania of six likely comets around distant stars suggests that comets--dubbed exocomets--are just as common in other stellar systems with planets.
and dust#a signature of exoplanets--makes it highly likely they all do said Barry Welsh a research astronomer at UC Berkeley's Space sciences Laboratory.
In 2009 astronomers found a large planet around Î-Pic about 10 times larger than Jupiter.
Astronomers using the National Science Foundation's (NSF) Green Bank Telescope (GBT) have discovered that filaments of star-forming gas near the Orion Nebula may be brimming with pebble-size particles--planetary building blocks 100
The large dust grains seen by the GBT would suggest that at least some protostars may arise in a more nurturing environment for planets said Scott Schnee an astronomer with the National Radio astronomy Observatory (NRAO) in Charlottesville Virginia.
Astronomers speculate that in the next 100000 to 1 million years this area will likely evolve into a new star cluster.
Based on earlier maps of this region made with the IRAM 30 meter radio telescope in Spain the astronomers expected to find a certain brightness to the dust emission
Rather than typical interstellar dust these researchers appear to have detected vast streamers of gravel--essentially a long and winding road in space said NRAO astronomer Jay Lockman who was involved not in these observations.
and there could be other explanations for the bright signature we detected in the emission from the Orion Molecular Cloud concluded Brian Mason an astronomer at the NRAO
Since it contains one of the highest concentrations of protostars of any nearby molecular cloud it will continue to excite the curiosity of astronomers.
Called the Hypatia Catalog after one of the first female astronomers who lived 350 AD in Alexandria the work is critical to understanding the properties of stars how they form
Since it is not possible to physically sample a star to determine its composition astronomers study of the light from the object.
and it is one of the most important tools that an astronomer has for studying the universe.
The most obvious one for astronomers is looking at stars who host extrasolar planets or exoplanets.
How the cosmic dust is formed has long been a mystery to astronomers. The elements themselves are formed out of the glowing hydrogen gas in stars.
#Astronomers complete cosmic dust censusan international team of astronomers has completed a benchmark study of more than 300 galaxies producing the largest census of dust in the local Universe the Herschel Reference Survey.
The two cameras on board the Herschel satellite SPIRE and PACS allowed astronomers to probe different frequencies of dust emission
will help astronomers to further unveil the mystery of cosmic dust in galaxies in the years to come.
and the geologic earthquake evidence coincides with written accounts describing local earthquake damage including damage to Spanish missions in 1838 and in a USGS publication of earthquakes in 1890 catalogued by an astronomer from Lick Observatory.
