Who or what is responsible for the black blobs shown in this shot taken by the Hubble Space Telescope? In cold, thick molecular clouds, the process of star formation is taking place. Using visible light, the top panorama depicts our perspective of the Milky Way from all directions as it appears in the visible spectrum. The creation of the Milky Way Galaxy is shown in these series of artworks.
What was the process through which the Hubble Space Telescope captured its first image?
- A region so tiny that the light acquired by the telescope over the course of 10 consecutive days is similar to the quantity of sky seen through the eye of a needle held at arms length. This image, dubbed the ” Hubble Deep Field,” was the first in a series of photographs that came to be known as the Hubble Deep Field images.

What are the basic characteristics of stars orbits in the disk halo and bulge of our galaxy?
Explanation: The orbits of the disks are more or less circular, and they all lie close to the plane. With the exception of a small amount of up- and-down motion, the disk stars orbit in circles with the same orientation. The orbits of the halo and bulge are substantially less well-organized: they range from spherical to extremely elliptical in shape, and they do not lie on a plane.
Which one is located closest to a place where evidence suggests we would find a 4 million solar mass black hole?
Which of the four designated stars is the most closely associated with a location where evidence says we might be able to detect a black hole with a mass of 4 million solar masses? Two sources of strong evidence supporting the presence of a huge black hole are the orbits of stars around the galactic center, as well as radio and X-ray radiation from the surrounding plasma.
What kind of star is most likely to be found in the halo?
They are known to as population II stars since they are old and have little heavy elements. They may be found in the halo and in globular clusters. Individual population I stars have higher concentrations of heavy elements than stars in globular clusters or haloes, and are often younger and more widespread throughout the disk, with a particular concentration near the spiral arms.
What can we learn about Sgr A by analyzing these orbits?
What can we infer about Sgr A’s orbits by examining these data points? We can determine the mass of the black hole in the galactic core based on the orbits of stars in the galactic center, which we see. Rank the following sites in order of their distance from the center of the Milky Way Galaxy, starting with the farthest and working your way closer.
What are the basic characteristics of stars orbits in the disk halo and bulge of our galaxy quizlet?
What are the fundamental properties of the orbits of stars in our galaxy’s disk, halo, and bulge regions? The disk stars have orbits that are approximately round in shape. They exhibit vertical movements out of the plane, giving the impression that they are bobbling up and down, yet they never appear to be “too far” away from the disk.
How do the orbits of disk stars and halo stars differ?
What is the reason for the differences in their orbits? Disk stars and halo stars orbit the galactic center at various inclinations because halo stars are spherical and disk stars are basically flat, whereas disk stars and halo stars orbit the galactic center at distinct inclinations.
Where are black holes located?
Supermassive black holes, according to astronomers, are believed to lurk at the heart of practically all major galaxies, including our own Milky Way. Their presence can be detected by astronomers by keeping an eye out for their impacts on neighboring stars and gas.
Why are black holes at the center of galaxies?
According to popular belief, they reside in the core of every galaxy because they have such gravitational force and strength that they can draw the rest of the dust, asteroids, planets, and suns into their gravitational gravity gravitational pull. Everything that is just far enough away will come together to create the galaxy, while everything else will become meal for the black hole.
How many black holes are in our galaxy?
There are approximately 100 billion stars in the Milky Way galaxy. It is estimated that one out of every thousand newly formed stars will be big enough to become a black hole. As a result, our galaxy must contain around 100 million black holes of star mass. The vast majority of them are invisible to humans, and just a handful have been identified thus far.
What is the evidence for dark matter in our galaxy?
The presence of dark matter has been confirmed via gravitational lensing and X-ray emission from giant galaxy clusters, among other methods. Galaxies and clusters of galaxies contain around ten times the amount of dark matter found in the universe’s light stuff.
Where are population 2 stars found?
Stars like RR Lyrae, as well as stars from the Population II, may be found in the halos of spiral galaxies and in globular clusters across the Milky Way galaxy system. In addition to elliptical galaxies, large numbers of these objects may be seen there as well.
What is found almost exclusively in the disk of the Milky Way?
The Milky Way galaxy is depicted in this figure. A population I star is defined as one that is located nearly entirely in the Galactic disk. The O, B, and open cluster stars are examples of population I stars. The Galactic Bulge, Galactic Halo, and globular clusters are all dominated by stars from the second generation of the Sun. A kiloparsec (kpc) is approximately 3,262 light years in length.
What was the name of the orbiting telescope that helped explore space by taking images like this one?
The Hubble Space Telescope orbits the Earth once every 95 minutes, completing one full circle.
Which telescope discovered these bubbles?
Fermi Bubbles are so named because they were found by the Fermi Gamma-Ray Space Telescope in 2010 and have since gained widespread attention. Each of these bubbles is massive, stretching out for around 50,000 light years from the Milky Way’s disk and traveling at a speed of millions of miles per hour.
What kind of object do we think lies in the center of the Milky Way galaxy?
A spectacular phenomenon may be found near the galactic nucleus: a gigantic black hole surrounded by an accretion disk of high-temperature plasma, which is the most massive object known to science. Because of the dense layer of dust that separates the core object from the surrounding material at optical wavelengths, neither the central object nor any of the material immediately around it can be detected at these wavelengths.
