Sentences with phrase «nearest galactic»

«Even though the Large Magellanic Cloud is one of our nearest galactic companions, we expect it should share some uncanny chemical similarity with distant, young galaxies from the early universe,» said Marta Sewiło, an astronomer with NASA's Goddard Space Flight Center in Greenbelt, Maryland, and lead author on a paper appearing in the Astrophysical Journal Letters.

One of the nearest galactic neighbors — the Sagittarius dwarf spheroidal — lurks invisibly behind the Milky Way's center.

Ghez says other stars with infrared excesses exist near the galactic center.

One possible cause for the outflows is a star - making frenzy near the galactic center that produces supernovas, which blow out gas.

However, we find a significant variation of the fraction of cool dwarfs with galactic latitude, indicating a target selection bias due to interstellar reddening and the increased contamination by giant stars near the galactic plane.

Most of the radio radiation is in or near the galactic equator.

The dust clouds of the Galaxy are narrowly limited to the plane of the Milky Way, though very low - density dust can be detected even near the galactic poles.

«In fact, given our current understanding of how stars form and the properties of the galactic center, it's [stellar evolution near the galactic center is] not allowed to happen.»

The more distant of these lies some 65,000 light years from the galactic centre, near the outer edge of the Milky Way's outermost arm (arxiv.org/abs/1006.1277).

To take a better galactic census, a team led by astronomer Rodrigo Ibata of the Strasbourg Observatory in France took the most detailed images yet of the space around Andromeda, exposing swarms of faint stars distributed near the galaxy.

Previously, astronomers have used x-ray telescopes to observe strong winds very near the massive black holes at galactic centers (artist's concept, inset) and infrared wavelengths to detect the vast outflows of cool gas (bluish haze in artist's concept, main image) from such galaxies as a whole, but they've never done so in the same galaxy.

Scientists using NASA's Hubble Space Telescope have discovered that the immense halo of gas enveloping the Andromeda galaxy, our nearest massive galactic neighbor, is about six times larger and 1,000 times more massive than previously measured.

So, how can the angular momentum be removed from the gas circling near an active galactic nucleus?

Things are pretty quiet in our part of the Milky Way, but astronomers have long suspected that our home galaxy might be a galactic cannibal, brutalizing and consuming its nearest neighbors.

Also expected in the near future is the Korean Microlensing Network (KMT - Net) that will operate telescopes in South Africa, Chile, and Australia using 1.6 meter telescopes covering 4 square degrees of the galactic bulge.

Then, beyond the Milky Way, there are a bunch of dwarf galaxies that are galactic satellites of the Milky Way (Cannis Major, Sagittarius), but the nearest full - size galaxy is Andromeda, which is two million light years away.

All galaxies, including our own, are believed to be embedded in and surrounded with halos of dark matter, which is what astronomers posit causes stars far from the galactic center to move as fast as those near the center.

Because gravity depends upon mass, you might think that most of a galaxy's mass would lie in the galactic disk or near the center of the disk.

Most of the stars in the central bulge and in the globular clusters of the galactic halo are old, low metals stars, and halo stars account for only 0.1 to 0.2 percent of the stars near Sol.
