What is the distance between Jupiter and the sun? How far are the outer planets from the Sun? How long is the Earth's orbit? How fast does the Hubble Telescope travel? Approximately how long does it take the sun to orbit the center of the milky way galaxy?
There is a strong belief that many comet's furthest point from the Sun lies around 50,000 A.U., roughly 1 Light Year or 50,000 times the distance between Earth and the Sun. Apart from being associated with the Oort Cloud, Jan also calculated that the centre of the Milky Way is 30,...
A real breakthrough in parallax measurement and therefore in determining distances of stars in our galaxy, theMilky Way, came with a mission calledHipparchos, after the ancient Greek astronomer that first used the method to estimate the distance of the moon. This mission, launched by ESA in 1...
When man began to search the skies,he saw a lot of things.In the universe,the earth seemed to be just a small bit of dust.It is only a small planet,and travels around the sun.The sun together with its planets,travels in the Milky Way,our galaxy.The Milky Way has about thirty ...
Accurate astronomical distance determination is crucial for all fields in astrophysics, from Galactic to cosmological scales. Despite, or perhaps because of, significant efforts to determine accurate distances, using a wide range of methods, tracers, and techniques, an internally consistent astronomical di...
What is the angular distance between the moon and procyon? How far away can the Hubble Telescope see? What are some features of the Hubble Telescope? What is X-ray astronomy used for? Explain how do astronomers observe the spiral structure of the ...
NIR data will allow us to (1) Explore the recent correlation between optical luminosity and host galaxy mass; (2) Improve our understanding of intrinsic colors of SNeIa; (3) Compare high- resolution NIR spectra and photometry; (4) Study the nature of dust in galaxies beyond our Milky Way....
systems like our own Milky Way. With the discovery of Cepheids in the Andromeda Galaxy by Edwin Hubble in 1926 and the determination of the huge distances to external galaxies like our own, it finally became clear that the Milky Way is only the nearest of these “Island ...
The distance between the planets and the sun is measured in the unit of AU (Astronomical Unit). The distance between the earth and the sun is considered as 1.000 AU. The distance between the sun and the mercury planet is 0.387 AU. Likewise, other planet's distance is also represented ...
Andromeda Galaxy, great spiral galaxy in the constellation Andromeda, the nearest large galaxy. It is one of the few visible to the unaided eye, appearing as a milky blur. The Andromeda Galaxy is located about 2,480,000 light-years from Earth, and its di
