Sentences with phrase «cloud near the star»

Such stars are rich in carbon, and it is believed that the fall in brightness is due to the star's emission of carbon, which then condenses to a dense cloud near the star, rather than to a change in luminosity of the star itself.

Now, a team of astronomers has used position and velocity data from the Sloan Digital Sky Survey as well as computer simulations of stellar evolution in the Large Magellanic Cloud (LMC, pictured above), a small satellite galaxy near the Milky Way, to show that these speeding stars may come from there.

Unlike the Solar System where most of the gravitational pull comes from the Sun and is simple to model, it is much harder to describe the gravitational field near the centre of the Galaxy, where millions of stars, vast clouds of dust, and even dark matter swirl about.

Even a near miss of the Oort cloud by a passing star might be enough of a gravitational tug to redirect some comets toward the inner solar system; Gliese 710, by current estimates, will pass right through.

Olsen says the stars share the motion of gas streams near the Large Magellanic Cloud, suggesting that the galaxy tore not only stars but also gas from its lesser neighbor.

This unusually compact cloud of dust and gas near the center of the Milky Way in the direction of the constellation Sagittarius is energized by a hot young star at its core, and it's a veritable alphabet soup of molecules.

This image of the nearby barred spiral galaxy NGC 1672 gives a detailed view of its star - forming cloud, including intense regions of star formation near the ends of the galaxy's central bar.

And yet stars can be observed forming furiously in at least a dozen different major clouds near the center.

Over the next several years, new infrared measurements showed that much of the gas and clouds and even entire stars nearest the center weren't simply rotating with the rest of the galaxy.

For this to occur, outside forces would have to compress the gas clouds near the center of our galaxy to overcome the violent nature of the region and allow gravity to take over and form stars.

Since his prediction, Alfvén waves have been associated with a variety of sources, including nuclear reactors, the gas cloud that envelops comets, laboratory experiments, medical MRI imaging and in the atmosphere of our nearest star — the Sun.

It covers the Orion A molecular cloud, the nearest known massive star factory, lying about 1350 light - years from Earth, and reveals many young stars and other objects normally buried deep inside the dusty clouds.

The Soul Nebula is an open cluster of stars surrounded by a cloud of dust and gas over 150 light - years across and located about 6,500 light - years from Earth in the constellation Cassiopeia, near the Heart Nebula.

Thanks to ALMA, astronomers will be able to make detailed images of stars and planets being born in gas clouds near our Solar System and to better understand how stars, planetary systems and even life itself formed.

A third theory suggests inner Oort cloud objects are captured extrasolar planets from other stars that were near our Sun in its birth cluster.

This orbits places the planet near the inner edge of its host star's habitable zone, where liquid water could exist in liquid form under favorable conditions such as an albedo of 0.52 with an orbital eccentricity of 0.11 and more than 52 percent cloud cover under a sufficiently dense atmosphere of water, carbon dioxide, and molecular nitrogen like Earth's (ESO science release; Pepe et al, 2011; and Kaltenegger et al, 2011 — more below).

Furthermore, the T Tauri star - disk systems within 100 pc of the Sun tend to be older, on average, than the large numbers of star - disk systems that are still found in or near their natal dark clouds.
