Globular cluster

1ml per sample. The samples were incubated at 4⁰C overnight. The following day, the samples were washed with DPBS at 4⁰C and then washed with 2ml 1 perm buffer twice. Anti-mouse Foxp3- PE Ab was added in a 1:100 dilution for 30 mins at 4⁰C. The samples were washed with perm buffer and resuspend in DPBS for flow cytometry analysis.

open clusters, globular clusters exist as far greater, spherical collections of aged stars that contain many low mass stars, sometimes numbering among the thousands. Globular clusters are more commonly found among a galaxy’s centre where the vast majority of stars are. It is thought that globular clusters arise from large gas clouds early in the creation of our universe and they assist the formation of greater galaxies. (Sparrow, G 2011, p. 180). Omega Centauri is a large globular cluster with…

The most famous celestial bond, except for the rings of Saturn, is the Ring Nebula or also known as M57. The Ring Nebula is 2,000 light years away and as seen on Earth the nebula looks like a donut-like ring wrapped around the middle of a football shaped cloud of glowing gas. It’s about one light year across and the glowing light the Ring Nebula produces is not coming from the planets but rather from the hot central star ionizes atoms in the gas forming intense ultraviolent light. As seen…

Nebula, showcase an assortment of colours twisted in a variety of puzzling shapes. There are also globular and open star clusters, which are giant groups of stars. The main difference comes down to the number of stars in each cluster, with a globular cluster containing tens of thousands of stars while open clusters contain merely hundreds to thousands of stars. My favourite, the Jewel Box open star cluster accommodates just over one hundred gems of the night sky. Walt Whitman summarises my…

SCORPIUS Scorpius, also known as Scorpio. Its name is Latin for Scorpion. It lies between Libra to the west and Sagittarius to the east. Scorpius is a large constellation in the southern hemisphere near the centre of the Milky Way. In Greek mythology, Scorpion was sent by Artemis, the goddess of hunting and her mother, Leto, to protect all the creatures since Orion said that he would kill all the creatures on the earth. After a battle, Scorpion killed Orion. Later, Zeus sent Scorpion into…

ancient stars, globular clusters, that orbit the halo of our galaxy. Along with the billions of stars and planets, the Milky Way also contains many solar systems and smaller black holes, although scientists do not have much proof of such existences, scientists can reasonably explain their hidden presence. 2.…

NGC 584 is an elliptical galaxy in the constellation Cetus. The galaxy was discovered on 10 September 1785 by the German-British astronomer William Herschel. Number 20 in the Herschel 400 list is NGC 584. NGC 584 is a moderately large and bright elliptical galaxy in Cetus. In an 18 inch telescope it appears as an elongated patch of light with a bright center. The two bright galaxies either side of NGC 584 are the 13.2 magnitude NGC 582; (left) and the 15.2 magnitude PGC 1028168. (Right). While…

better picture of the typical architecture of spiral galaxies. Though the galaxy is 11.6 million light-years away, the vision of the NASA/ESA Hubble Space Telescope is so sharp that it can resolve individual stars, along with open star clusters, globular star clusters, and even glowing regions of fluorescent gas. The spiral arms, which wind all the way down into the nucleus, are made up of young, bluish, hot stars formed in the past few million years. They also host a population of stars formed…

Rebecca McKenney Frontiers of Astronomy Mrs. Alburg 26 April 2017 Our Galactic Universe 1. Galaxies can be as large as a few thousand to several hundreds of thousands of light years across. 2. Astronomers, at the time this was released, believe that there are over a hundred billion galaxies in the universe. 3. It is estimated that a light year is 5.88 trillion miles. 4. Galaxies come in three different main type shapes. There are spiral, elliptical, and irregular. 5. Spiral galaxies…

CYGNUS One of the most prominent constellations in the night sky, and one of the most involved and eventful regions of space, the Cygnus constellation and its surrounds are fascinating, and a worthwhile talking point for many a topic. Occupying an area of 804 square degrees, Cygnus is the 16th largest constellation in the night sky; it lies in the fourth quadrant of the northern hemisphere, with right ascension at 20.62, and declination at +42.03: in other words, if you were in the northern…
