The Young Age Of Globular Clusters The Young Age Of Globular Clusters By Paul Nethercott January 2013 Introduction Globular clusters are considered by evolutionists to be the oldest structures in the universe.1-4 According to a recent astronomy magazine article they are over ten billion years old. 4 When neutron stars are formed they are ejected [kicked] out at hundreds of kilometres per second. The time to escape from the centre to the outer edge is only a few thousand years. If they form only once every million years per cluster there should only be a few in every cluster. Many clusters have hundreds or thousands which indicates youth. This lines up with them being created only a few thousand years ago. A recent article admits this is a problem that evolutionists need to resolve: “There is mounting evidence that as many as 1000 neutron stars (NSs) may be present in some of the richest globular clusters in the Galaxy, which perhaps amounts to more than 10%–20% of the NSs ever formed in each cluster. Such a large NS retention fraction is seemingly at odds with recent estimates of the characteristic “kick” speeds of single radio pulsars in the Galaxy, ranging from roughly 5 to 10 times the central escape speeds of the most massive globular clusters. This retention problem is a long-standing mystery.”5 If we know the radius of the globular cluster and how fast the stars are shot out we can work out escape times. We find the ratio of the stars velocity to the speed of light and multiply the inverse by the radius of the cluster: c t r v (1) T= escape time in years C= Velocity of light, kilometres per second. V= Velocity of neutron star, kilometres per second. R = Radius of the globular cluster in light years In the table below we can see a summary for 148 globular clusters.6 Even at a slow speed of only 50 kilometres per second, the maximum age is only 5.5 million years. Using a very modest speed of 200 kilometres per second would give an average age of only 200 thousand years. The clusters a supposed to be billions of years old! Table 1.

He created a list of distracting objects to avoid while comet hunting. This list now contains over 110 objects, many of which are the most famous astronomical bodies known. The list contains planetary nebula, star clusters, and other galaxies. - Bobby Martinez The Telescope The telescope used to take these images is an Astronomical Consultants and Equipment (ACE) 24- inch (0.61-meter) Ritchey-Chretien reflecting telescope. It has a focal ratio of F6.2 and is supported on a structure independent of the building that houses it. It is equipped with a Finger Lakes 1kx1k CCD camera cooled to -30o C at the Cassegrain focus. It is equipped with dual filter wheels, the first containing UBVRI scientific filters and the second RGBL color filters. Messier 1 Found 6,500 light years away in the constellation of Taurus, the Crab Nebula (known as M1) is a supernova remnant. The original supernova that formed the crab nebula was observed by Chinese, Japanese and Arab astronomers in 1054 AD as an incredibly bright “Guest star” which was visible for over twenty-two months. The supernova that produced the Crab Nebula is thought to have been an evolved star roughly ten times more massive than the Sun.

    VISTA Views a Vast Ball of Stars 9 May 2012

    VISTA views a vast ball of stars 9 May 2012 sphere with a diameter of only about 25 times the distance between the Sun and the nearest star system, Alpha Centauri. About 160 globular clusters have been spotted encircling our galaxy, the Milky Way, mostly toward its bulging centre. The two latest discoveries, made using VISTA, were recently announced. The largest galaxies can have thousands of these rich collections of stars in orbit around them. Observations of globular clusters' stars reveal that they originated around the same time - more than 10 billion years ago - and from the same cloud of gas. As this formative period was just a few billion years after the Big Bang, nearly all of the gas on hand was the simplest, lightest and most common in the cosmos: hydrogen, along with some helium and much smaller amounts of heavier chemical elements such as oxygen and nitrogen. This striking view of the globular star cluster Messier 55 Being made mostly from hydrogen distinguishes in the constellation of Sagittarius (The Archer) was globular cluster residents from stars born in later obtained in infrared light with the VISTA survey eras, like our Sun, that are infused with heavier telescope at ESO's Paranal Observatory in Chile.

"But, first of all, it will be necessary to explain what is our idea of a cluster of stars, and by what means we have obtained it. For an instance, I shall take the phenomenon which presents itself in many clusters: It is that of a number of lucid spots, of equal lustre, scattered over a circular space, in such a manner as to appear gradually more compressed towards the middle; and which compression, in the clusters to which I allude, is generally carried so far, as, by imperceptible degrees, to end in a luminous center, of a resolvable blaze of light."

  • A Basic Requirement for Studying the Heavens Is Determining Where In

    A Basic Requirement for Studying the Heavens Is Determining Where In

    Abasic requirement for studying the heavens is determining where in the sky things are. To specify sky positions, astronomers have developed several coordinate systems. Each uses a coordinate grid projected on to the celestial sphere, in analogy to the geographic coordinate system used on the surface of the Earth. The coordinate systems differ only in their choice of the fundamental plane, which divides the sky into two equal hemispheres along a great circle (the fundamental plane of the geographic system is the Earth's equator) . Each coordinate system is named for its choice of fundamental plane. The equatorial coordinate system is probably the most widely used celestial coordinate system. It is also the one most closely related to the geographic coordinate system, because they use the same fun­ damental plane and the same poles. The projection of the Earth's equator onto the celestial sphere is called the celestial equator. Similarly, projecting the geographic poles on to the celest ial sphere defines the north and south celestial poles. However, there is an important difference between the equatorial and geographic coordinate systems: the geographic system is fixed to the Earth; it rotates as the Earth does . The equatorial system is fixed to the stars, so it appears to rotate across the sky with the stars, but of course it's really the Earth rotating under the fixed sky. The latitudinal (latitude-like) angle of the equatorial system is called declination (Dec for short) . It measures the angle of an object above or below the celestial equator. The longitud inal angle is called the right ascension (RA for short).

Received YYY; in original form ZZZ ABSTRACT Globular clusters (GCs) are the most ancient stellar systems in the Milky Way. There- fore, they play a key role in the understanding of the early chemical and dynamical evolution of our Galaxy. Around 40% of them are placed within ∼ 4 kpc from the Galactic center. In that region, all Galactic components overlap, making their disen- tanglement a challenging task. With Gaia DR2, we have accurate absolute proper mo- tions for the entire sample of known GCs that have been associated with the bulge/bar region. Combining them with distances, from RR Lyrae when available, as well as ra- dial velocities from spectroscopy, we can perform an orbital analysis of the sample, employing a steady Galactic potential with a bar. We applied a clustering algorithm to the orbital parameters apogalactic distance and the maximum vertical excursion from the plane, in order to identify the clusters that have high probability to belong to the bulge/bar, thick disk, inner halo, or outer halo component.

Weiss1 Max-Planck-Institut für Astrophysik, Karl-Schwarzschild-Str. 1, 85748 Garching, Germany e-mail: [meissner;weiss]@mpa-garching.mpg.de Received 3 March 2006 / Accepted 12 June 2006 ABSTRACT Context. Stellar models and the methods for the age determinations of globular clusters are still in need of improvement. Aims. We attempt to obtain a more objective method of age determination based on cluster diagrams, avoiding the introduction of biases due to the preference of one single age indicator. Methods. We compute new stellar evolutionary tracks and derive the dependence of age indicating points along the tracks and isochrone – such as the turn-off or bump location – as a function of age and metallicity. The same critical points are identified in the colour-magnitude diagrams of globular clusters from a homogeneous database. Several age indicators are then fitted simultaneously, and the overall best-fitting isochrone is selected to determine the cluster age. We also determine the goodness-of-fit for different sets of indicators to estimate the confidence level of our results. Results. We find that our isochrones provide no acceptable fit for all age indicators. In particular, the location of the bump and the brightness of the tip of the red giant branch are problematic. On the other hand, the turn-off region is very well reproduced, and restricting the method to indicators depending on it results in trustworthy ages. Using an alternative set of isochrones improves the situation, but neither leads to an acceptable global fit.

See the NASA- processed image and other Messier objects at: https://www.nasa.gov/content/goddard/hubble-s- messier-catalog. Provided by NASA's Goddard Space Flight Center Hubble image of Messier 75, taken with the telescope's Advanced Camera for Surveys. Credit: ESA/Hubble & NASA, F. Ferraro et al. This sparkling burst of stars is Messier 75. It is a globular cluster: a spherical collection of stars bound together by gravity. Clusters like this orbit around galaxies and typically reside in their outer and less-crowded areas, gathering to form dense communities in the galactic suburbs. Messier 75 lies in our Milky Way galaxy in the constellation of Sagittarius (the Archer), around 67,000 light-years away from Earth. The majority of the cluster's stars, about 400,000 in total, are found in its core; it is one of the most densely populated clusters ever found, with a phenomenal luminosity of some 180,000 times that of the Sun. No wonder it photographs so well! Discovered in 1780 by Pierre Méchain, Messier 75 was also observed by Charles Messier and added to his catalog later that year. This image of Messier 75 was captured by the NASA/ESA Hubble Space Telescope's Advanced Camera for Surveys.
