Its principal aimis to provide an improved calibration of the local extragalactic distance scale.
Extragalactic astronomy is the branch of astronomy concerned with objects outside the Milky Way galaxy.
More surprising still,spectral analysis suggests that the infant stars have an extragalactic origin.
An extragalactic planet, also known as an extragalactic exoplanet, is a star-bound planet, or rogue planet, located outside of the Milky Way Galaxy.
Astronomer Art Hoag firstasked this question when he chanced upon this unusual extragalactic object.
Thus the observed radiation density(the sky brightness of extragalactic background light) can be independent of finiteness of the universe.
Surveys in the infrared, such as IRAS and 2MASS,have given a more complete picture of the extragalactic sky.
Even so,approximately 10% of the sky remains difficult to survey as extragalactic objects can be confused with stars in the Milky Way.
This question came to light in 1950 whenastronomer Art Hoag chanced upon this unusual extragalactic object.
Key projects involving LOFAR include extragalactic surveys, research into the nature of cosmic rays and studies of space weather.
Bottom line:Supercomputer simulations suggest that each one of us may be made in part from extragalactic matter.
This is in contrast to extragalactic astronomy, which is the study of everything outside our galaxy, including all other galaxies.
These active galactic nuclei(AGN)are among the most dramatic and interesting phenomena in extragalactic astronomy, and puzzling as well.
What we know is that gamma-ray photons from extragalactic sources travel in the universe toward Earth, where they can be absorbed by interacting with the photons from starlight.
Sub-GeV dark matter has been used to explain the positron excess in the galactic center observed by INTEGRAL,excess gamma rays from the galactic center[7] and extragalactic sources.
The Araucaria Project-international science collaboration focused on improving calibration of the extragalactic distance scale based on observations of major distance indicators in several nearby galaxies.
There is a strong direct relationship between a Cepheid's luminosity and pulsation period.[1][2]This makes Cepheids important standard candles for the galactic and extragalactic distance scales.[3].
H II regions can be observed at considerable distances in the universe,and the study of extragalactic H II regions is important in determining the distance and chemical composition of galaxies.
When viewing space from Earth, the attenuation, interstellar dust, and stars in the plane of the Milky Way(the galactic plane)obstruct the view of around 20% of the extragalactic sky at visible wavelengths.
H II regions can be seen out to considerable distances in the universe,and the study of extragalactic H II regions is important in determining the distance and chemical composition of other galaxies.
Research today at the McDonald Observatory encompasses a wide variety of topics and projects, including planetary systems, stars and stellar spectroscopy,the interstellar medium, extragalactic astronomy, and theoretical astronomy.
In the process of setting up the extragalactic distance scale, the greatest difficulty leading to the currently largest contribution on the systematic uncertainty of the Hubble constant lies in the determination of accurate absolute distances to nearby galaxies.
A planet with a mass of at least 1.25 times that of Jupiter had been potentially discovered by the European Southern Observatory(ESO)orbiting a star of extragalactic origin, even though the star now has been absorbed by our own galaxy.
Nonetheless, the Hubble sequenceis still commonly used in the field of extragalactic astronomy and Hubble types are known to correlate with many physically relevant properties of galaxies, such as luminosities, colours, masses(of stars and gas) and star formation rates.[27].
This well-documented event in our own Milky Way Galaxy is probably related to a class of faint stellar explosions in other galaxiesrecognized in recent years by telescopes searching for extragalactic supernovae.
The unidentified infrared emission(UIR or UIE) bands are infrared discrete emissions from circumstellar regions, interstellar media,star-forming regions and extragalactic objects for which the identity of the emitting materials is unknown.
Whether FRB 121102 is a unique object in the currently known sample of FRBs, or all FRBs are capable of repeating,its characterisation is extremely important to understanding fast extragalactic radio transients,” the team writes.

Previously thought to belong to our galaxy at a distance from Earth of about 50,000 light-years, it was discovered in 1994 that M54 most likely belongs to the Sagittarius Dwarf Elliptical Galaxy(SagDEG),[7] making it the first globular cluster formerlythought to be part of our galaxy reassigned to extragalactic status, even if not recognized as such for nearly two and a quarter centuries.
