Our children may never know the revolutionary pleasure the videogame Halo: Combat Evolved was when it appeared with a story, plot and overall entertainment value that put everything else to shame. But the universe won’t. We found Halo. In a manner of speaking. Astronomers and the general public have been inspired by the amalgam of structures discovered in deep space, however, today they announced the existence of an unimaginably massive structure composed of a loose ellipse of galaxies, roughly 5 billion light years in diameter.
This intergalactic halo was limned indirectly by 9 observed gamma-ray bursts, and has been triangulated at about 7 billion light years’ distance. From the ground, the ring spans a distance that’s 70 times the diameter

When it’s born, the black hole releases spectacular beams of energy coming out at a normal angle with respect to the black hole’s rotation. If earth is lucky (or unlucky) enough to be aligned with these beams, a climactic signal registers on scientists’ equipment, and with the information contained in the signal (e.g., direction, magnitude, dissipation), astronomers are able to ascertain the distance and location of the gamma-ray …show more content…
This is actually a precept of the science, called the “Cosmological Principle,” and it’s already found ground in the form of NASA’s Wilkinson Microwave Anisotropy Probe (WMAP) and Europe’s Planck Space Telescope, both of which catalogue cosmic microwave background (CMB) radiation.
Until recently, the upper-limit for cosmic structures was 1.2 billion light-years across, but this gamma-ray burst halo is 5 times the size of that limit. That’s a theoretical discrepancy no trade could ignore. What’s more, another structure of gamma-ray bursts was discovered, spanning a distance of 10 billion light-years.
What madness is responsible for this super-geometry? Some macro-cosmology holds that there are areas of our universe which clump together in web-like strands that flow for billions of light-years, creating “holes” in the universe, where little to no matter or energy is present. But presently, this newest structure creates a super-void that puts even the most superlative absences to
Halo: Reach is a first-person shooter video game developed by Bungie, published by Microsoft Game Studios, and released on September 14, 2010, for the Xbox 360 video game console. Players control Noble Six, a member of an elite supersoldier squad, when the human world known as Reach is attacked in the year 2552 by the alien Covenant. Developed after the 2007 release of Halo 3, the game is a prequel to the original Halo game trilogy. Reach 's music was composed by longtime Halo composers Martin O'Donnell and Michael Salvatori, who aimed for a more somber sound to match the story. Reach was announced at the Electronic Entertainment Expo 2009 in Los Angeles. It grossed $200 million on its launch day, setting a new record for the franchise. The
Scientists using NASA's Hubble Space Telescope have discovered that the i halo of gas enveloping the Andromeda galaxy, our nearest massive neighbor, is about six times larger and 1,000 times more massive than previously measured. The dark, nearly invisible halo stretches about a million light-years from its host galaxy, halfway to our own Milky Way galaxy. One of the most common types of galaxies in the universe.
Throughout the modern era of astronomy, a single type of celestial object has puzzled astronomers more than any other. Black holes, whose existence was only verified in the early 1990’s, have fascinated scientists ever since Einstein first proposed the theoretical concept in the 1930’s. A black hole is an object so tiny, but also so dense, that it has the power to pull planets, stars, and even light into its core, and ultimately destroy everything in its path. Over the past decade much has been discovered about these enigmas of space and time; however, many of these recent discoveries lead to more unanswered questions. Nevertheless, the basic life cycle of a black hole is now understood in ways thought to be impossible only twenty years
Elizabeth Gibney discusses the history of fast radio bursts and astronomer’s strategy to finding them in the universe in her article, “Fast Radio Bursts are Astronomy’s Next Big Thing.” She begins by defining fast radio bursts as “fleeting blasts of energetic cosmic radiation of unknown cause.” (Gibney) Gibney briefly reviles that even though FBRs were discovered a decade ago, the phenomenon has just recently been accepted as genuine.
Distributed over 90 sq. deg. of the sky, they lie from 4 to 23 kpc from the Sun. The most significant group of RRLS is the Virgo Stellar Stream which is composed of at least 10 RRLS and 3 BHB stars. It has a mean distance of 19.6 kpc and a mean radial velocity Vgsr = 128 km/s, as estimated from its RRLS members. With the revised velocities reported here, there is no longer an offset in velocity between the RRLS in the VSS and the prominent peak in the velocities of main-sequence turnoff stars reported by Newberg et al in the same direction and at a similar distance. The location in phase space of two other groups suggests a possible connection with the VSS, which cannot be discarded at this point, although the turnoff colors of the VSS and group H, as identified from Newberg. Two more groups are found at mean distances of 19 and 5.7 kpc, and mean radial velocities of -94 and 32 km/s. None of our groups seems to relate to streams. The excess of stars observed in Virgo appears to be composed of several halo substructures along the same line of
multitudes something well known to astronomers: On the scale of worlds—to say nothing of stars
Images of the galaxy in the radio portion of the electromagnetic spectrum show two jets protruding in opposite directions from the galaxy's center. These jets extend many times the width of the portion of the host galaxy which emits radiation at visible wavelengths.[5] At the ends of the jets are two lobes with "hot spots" of more intense radiation at their edges. These hot spots are formed when material from the jets collides with the surrounding intergalactic medium.[6]
First observed in the early 70's \citep{Giacconi71, Tananbaum72}, the APPs are the brightest objects in the X-ray sky. Their powerful electromagnetic radiation is powered by the gravitational potential energy of the accreted matter. The accreting matter is directed by the magnetosphere onto the the magnetic poles of the star, thereby increasing its energy and angular momentum in the process. The rapid slowdown of the accreting matter at the polar surface of the star releases gravitational potential energy as X-rays, and the rotation of these X-ray hot spots across our line of sight gives rise to the observed periodic
By observing a brown dwarf 20 light-years away using both radio and optical telescopes, a team led by Gregg Hallinan, assistant professor of astronomy at Caltech, has found another feature that makes these so-called failed stars more like supersized planets, they host powerful auroras near their magnetic poles.
The Gamma-Ray Spectrometer or GRS instrument had three detector systems that measured the spectra of flare X-rays and gamma rays which showed that gamma ray emission from even modest flares was common and that particles are accelerated in flares to high energies in just a few
The Tadpole Galaxy is a disrupted barred spiral galaxy that is 420 million light-years from Earth towards Draco. It has a trail of stars about 280,000 light-years long and big, bright blue star clusters. Numerous young blue stars and star clusters, created by the galaxy collision, are seen in the spiral arms, as well as in the long tidal tail of stars. Each of these clusters contains up to a million stars and will redden with age to become in time globular clusters similar to those found in essentially all halos of large galaxies, including our own Milky Way. It is said that a more compact intruder galaxy crossed in front of the Tadpole Galaxy and was slung around behind the Tadpole by their mutual gravitational attraction. During this encounter,
Harper Lee’s classic, To Kill a Mockingbird, aims to portray the inequality and discrimination that ran rampant during the Jim Crow/Civil Rights era. It does so by showing the results of such discrimination through the eyes of a 6 year old child, Scout Finch. At the time, many expressed their displeasure of this viewpoint, but this was not the only reason the book was banned in many states. First of all, the heavily featured rape trial of Tom Robinson touched on a very tender subject in the United States at the time. In the 30’s and 40’s the role of women in society was generally accepted to be that of a homemaker, resulting in minimal discussion and thought on the subjects of rape and female sexuality.
In Vincent Van Gogh’s “Starry Night” he used five of the seven elements of art, including Space, color, line, texture, and shape/form to create a beautiful masterpiece. The art work goes into great detail, showing a small town, which uses shape/form and gives a satisfying setting and gives very much detail. The element line is what is used to create the art piece. The mood of the artwork, the sky, is created by using lines, “line is the most prominent elements in this painting,” Many different lines are put together, to create the sky, and the effect of the stars. He uses long, organic, short, sharp, and many other lines.
Billions of these strange dark matter particles pass through everything they encounter each second including Earth (Redd 2014). Dark matter is thought to be so massive its weight has the power to influence the galaxies, how they form and how fast they spin as Fritz Zwicky discovered (Dark Matter; The Undetectable Mass 2014). Dark mater’s presence is everywhere, there are many suspects but
The Helix Nebula also known as The Helix, NGC 7293, God’s Eye, and the Eye of Sauron, is a planetary nebula. It is around 10,000 years old. It is approximately 650 light-years from Earth and it spans about 2.5 to 3 light-years across. This intricately shaped planetary nebula is also located in the constellation of Aquarius. The Helix is a very interesting, complex planetary nebula to understand. Scientists
