Since the sun's absolute magnitude is 4. The name signifies that it was the rd object ordered by right ascension of the Third Cambridge Catalog of Radio Sources 3C , published in After accurate positions were obtained using lunar occultation by Cyril Hazard at the Parkes Radio Telescope , [8] the radio source was quickly associated with an optical counterpart, an unresolved stellar object.

In , Maarten Schmidt [5] and Bev Oke [9] published a pair of papers in Nature reporting that 3C has a substantial redshift of 0.

Prior to the discovery of 3C , several other radio sources had been associated with optical counterparts, the first being 3C However, it was not understood what these objects were, since their spectra were unlike those of any known stars.

Its spectrum did not resemble that of any normal stars with typical stellar elements. However, even to this day, the process which gives rise to the X-ray emissions is controversial.

Polarization with coincident orientation has been observed in radio, infrared , and optical light being emitted from the large-scale jet; these emissions are therefore almost certainly synchrotron in nature, [4] radiation that is created by a jet of charged particles moving at relativistic speeds.

Such jets are believed to be created by the interaction of the central black hole and the accretion disk. VLBI radio observations of 3C have revealed proper motion of some of the radio emitting regions, further suggesting the presence of relativistic jets of material.

Situated in the Virgo constellation, It is bright enough to be observed with larger amateur telescopes. Due in part to its radio luminosity and its discovery as the first identified quasar, 3C 's right ascension in the Fifth Fundamental Catalog FK5 is used to standardize the positions of 23 extragalactic radio sources used to define the International Celestial Reference System ICRS.

Given its distance from Earth and visual magnitude, 3C is the most distant celestial object average amateur astronomers are likely to see through their telescopes.

Light from these stars may have been observed in using NASA 's Spitzer Space Telescope , [56] although this observation remains to be confirmed.

The taxonomy of quasars includes various subtypes representing subsets of the quasar population having distinct properties.

Because quasars are extremely distant, bright, and small in apparent size, they are useful reference points in establishing a measurement grid on the sky.

Because they are so distant, they are apparently stationary to our current technology, yet their positions can be measured with the utmost accuracy by very-long-baseline interferometry VLBI.

The positions of most are known to 0. A grouping of two or more quasars on the sky can result from a chance alignment, where the quasars are not physically associated, from actual physical proximity, or from the effects of gravity bending the light of a single quasar into two or more images by gravitational lensing.

When two quasars appear to be very close to each other as seen from Earth separated by a few arcseconds or less , they are commonly referred to as a "double quasar".

When the two are also close together in space i. As quasars are overall rare objects in the universe, the probability of three or more separate quasars being found near the same physical location is very low, and determining whether the system is closely separated physically requires significant observational effort.

The first true triple quasar was found in by observations at the W. Keck Observatory Mauna Kea , Hawaii. When astronomers discovered the third member, they confirmed that the sources were separate and not the result of gravitational lensing.

A multiple-image quasar is a quasar whose light undergoes gravitational lensing , resulting in double, triple or quadruple images of the same quasar.

In this process, lower energy synchrotron light emitted by the jets is inverse Compton scattered by the same beam of relativistic electrons that created them.

When this happens, the photons get a huge energy boost at the expense of the electrons, creating X-rays and gamma-rays.

We can often see radio jets in AGN even if they are not aligned with our line of sight, but normally, in order to detect the highest-energy X-rays and gamma-rays, we have to be looking "straight down the barrel" of the jet.

Many of the spectral and behavioral properties of AGN and quasars depend upon what orientation we're viewing the central engine and jet if any from.

It is believed that AGN will be brighter the more closely the jet is pointed in our direction, and that the quasars are viewed almost straight on.

In cases where the jet is almost exactly aligned with our line of sight, we see the most extreme example of AGN -- a blazar.

Blazars the name is a combination of BL Lac object and quasar are known for their gamma-ray emission, for their mostly featureless optical spectra, and for their rapid optical variability.

But it also has some spectral line features including emission lines of hydrogen in the optical, and iron lines in the X-ray.

The light from 3C is likely a combination of radiation from the accretion disk and from the bright jet. In many cases, we see jets from quasars and other AGN manifested as bright, extended radio galaxies , with fluffy lobes of radio emission billowing out to either side of the central engine.

These radio jets and lobes can sometimes extend for hundreds of kiloparsecs away from the central galaxy.

In most AGN, we only see these jets in radio light, but in principle, jets can generate synchrotron emission at any wavelength, so long as the particles accelerated by the jet have high enough energies -- the higher the energy of the electrons, the higher the energy of the photons you can get out.

In a few particularly energetic systems, we can see the jets emitted by the black hole at nearly every wavelength we look in.

One famous example is the jet of the giant elliptical galaxy Virgo A, or M The small optical jet near the core of this galaxy was detected in the early 20th century, and now radio and X-ray observations of this active galaxy show the jet is present at those wavelengths as well.

Another notable example of this is our Variable "Star" of the Season, 3C You can faintly see it in Digital Sky Survey images of this quasar, pointed directly away from the central source to the southwest.

The jet is perfectly aligned with the radio jet of 3C , and is believed to be synchrotron emission from the same source. The high-energy radiation comes mostly from knots in the jet, where the jet undergoes shocks as it runs into gas surrounding the central engine.

Observing 3C The quasar 3C is a point source around magnitude The long-term light curve of 3C has helped quasar theorists understand the behavior of these objects, and we urgently want the visual community to keep up the good work!

As with many astronomical objects, the light curves of quasars become more and more valuable the longer they get, and your visual observations have made an important contribution to the science of these exciting objects.

We've included the visual light curve, averaged over 1-year intervals for clarity, showing 3C 's behavior over the past 40 years. The quasar varies by a few tenths of a magnitude over its range, and these variations occur on a minimum of year-long timescales.

Previous work, including that of Smith and Hoffleit, showed that variations may even occur on timescales of months ; the visual light curve of the AAVSO hints at these variations because of the occasionally large year-to-year changes that may have shorter-timescale structure.

The maximum size of the varying region is defined as the amount of time it takes for light to travel during the course of the variation -- in this case, a few light months at most.

This shows that the central engine of 3C and indeed all quasars is small, much less than one parsec in diameter.

Like all quasars, 3C has a relatively flat continuum, indicating the high temperature of the continuum source.

What If a Quasar Entered Our Solar System?

If the R. The Declination is how far north or south the object is compared to the celestial equator and is expressed in degrees.

For 3C , the location is 12h 29m Based on the star's spectral type of Q 3C Radius 3C estimated radius has been calculated as being 0.

The Sun's radius is ,km, therefore the star's radius is an estimated , If you need the diameter of the star, you just need to multiple the radius by 2.

The figure is derived at by using the formula from SDSS rather than peer reviewed papers. It has been known to produce widely incorrect figures.

Apparent Magnitude is also known as Visual Magnitude. Using the supplied Parallax value, you would get an absolute magnitude of 5.

Our own Sun is the brightest star and therefore has the lowest of all magnitudes, A faint star will have a high number. Using the original Hipparcos data that was released in , the parallax to the star was given as 3.

If you want that in miles, it is about 5,,,,, The time it will take to travel to this star is dependent on how fast you are going. A minority of quasars show strong radio emission, which is generated by jets of matter moving close to the speed of light.

When viewed downward, these appear as blazars and often have regions that seem to move away from the center faster than the speed of light superluminal expansion.

This is an optical illusion due to the properties of special relativity. Quasar redshifts are measured from the strong spectral lines that dominate their visible and ultraviolet emission spectra.

These lines are brighter than the continuous spectrum. They exhibit Doppler broadening corresponding to mean speed of several percent of the speed of light.

Fast motions strongly indicate a large mass. Emission lines of hydrogen mainly of the Lyman series and Balmer series , helium, carbon, magnesium, iron and oxygen are the brightest lines.

The atoms emitting these lines range from neutral to highly ionized, leaving it highly charged. This wide range of ionization shows that the gas is highly irradiated by the quasar, not merely hot, and not by stars, which cannot produce such a wide range of ionization.

Like all unobscured active galaxies, quasars can be strong X-ray sources. Radio-loud quasars can also produce X-rays and gamma rays by inverse Compton scattering of lower-energy photons by the radio-emitting electrons in the jet.

Quasars also provide some clues as to the end of the Big Bang 's reionization. More recent quasars show no absorption region, but rather their spectra contain a spiky area known as the Lyman-alpha forest ; this indicates that the intergalactic medium has undergone reionization into plasma , and that neutral gas exists only in small clouds.

The intense production of ionizing ultraviolet radiation is also significant, as it would provide a mechanism for reionization to occur as galaxies form.

Quasars show evidence of elements heavier than helium , indicating that galaxies underwent a massive phase of star formation , creating population III stars between the time of the Big Bang and the first observed quasars.

Light from these stars may have been observed in using NASA 's Spitzer Space Telescope , [56] although this observation remains to be confirmed.

The taxonomy of quasars includes various subtypes representing subsets of the quasar population having distinct properties. Because quasars are extremely distant, bright, and small in apparent size, they are useful reference points in establishing a measurement grid on the sky.
