Redshift (and blueshift) may be characterized by the relative difference between the observed and emitted wavelengths (or frequency) of an object. In astronomy, it is customary to refer to this change using a dimensionless quantity called z.
The astronomical unit of mass is the mass of the Sun (S). The astronomical unit of length is that length (A) for which the Gaussian gravitational constant (k) takes the value 0.017 202 098 95 when the units of measurement are the astronomical units of length, mass and time.

The apparent brightness of a star depends on both its luminosity and its distance from Earth. Thus, the determination of apparent brightness and measurement of the distance to a star provide enough information to calculate its luminosity.
Located in the constellation Virgo, this galaxy is approximately 59 million light-years away from Earth and has a magnitude of 9.5. M90 is believed to be breaking away from the rest of the galaxies in the Virgo cluster and is one of the few galaxies traveling toward our Milky Way galaxy, not away.
The first major update to the NGC is the Index Catalogue of Nebulae and Clusters of Stars (abbreviated as IC), published in two parts by Dreyer in 1895 (IC I, containing 1,520 objects) and 1908 (IC II, containing 3,866 objects).
Astronomical Glossary. H. Chemical symbol for hydrogen. The most abundant chemical in the universe. H2is the symbol for the molecular hydrogen molecule which is abundant in giant clouds in our galaxy and can be detected by its infrared spectrum.
A: It's hard to get rich by being an astronomer, but most astronomers make enough money to live comfortably. The amount astronomers are paid depends on where the astronomer is working, how much experience the astronomer has, and even how prestigious the astronomer is.
On a daily basis, astronomers spend most of their time doing one of two things – analysing the data they've collected or researching what is happening and being discovered in their niche area of astronomy by reading other astronomers published papers. A theoretical astronomer generally doesn't use a telescope at all.
With solid training though, an astronomer could switch to a completely different job (a stock market analyst, an engineer) more readily than those in many other disciplines. But personally I consider it a good career, because one gets to ask many questions, and occasionally to answer some of them.
First of all, the majority of PhD astronomers/astrophysicists are still working in the field. So while it is a small field, there are definitely job opportunities to continue. These include academia, government agencies, and policy. But even if you leave the field, your opportunities are quite good.
Astronomers in research positions need advanced college degrees. Most aspiring astronomers begin their college-level studies in physics, though some earn a bachelor's degree in astronomy.
Salaries vary according to education, experience, and the type of employer. The median annual salary of astronomers was $97,320 in 2004. Benefits usually include paid holidays and vacations, health insurance, and pension plans.
The most important subjects to learn to become an astronomer, are physics, maths, and chemistry. Take everyone of these you can in high school, if you are thinking of pursuing astronomy (or any other “hard science”) in University. It will take some real hard work, but it is not difficult, per say.
Astronomy can be a very difficult major since upper-level physics is required, in addition to the (more interesting) astronomy courses. Definitely only take the major if you are really interested in physics. If you're just interested in learning about planets, solar systems, etc, consider taking it as a minor.
The starting salaries for astronomers or astrophysicists in postdoctoral research posts are normally in the range of £26,000 to £39,000 a year. Senior (or advanced) researchers and university lecturers earn up to £60,000 a year.
It is a spiral galaxy (like our galaxy, the Milky Way). It can just be seen with the naked eye. MACHO stands for Massive Compact Halo Object. MACHOs are objects that could account for some (or all) of the dark matter in the halos of galaxies, like white dwarfs, neutron stars, and black holes.

- Galactic Cannibalism. The Sagittarius Dwarf Galaxy will probably not be the first galaxy that has been 'eaten' by our galaxy.

In astronomy, magnitude is a unitless measure of the brightness of an object in a defined passband, often in the visible or infrared spectrum, but sometimes across all wavelengths. The brighter an object appears, the lower the value of its magnitude, with the brightest objects reaching negative values.
Magnitude, in astronomy, measure of the brightness of a star or other celestial body. The brighter the object, the lower the number assigned as a magnitude. In ancient times, stars were ranked in six magnitude classes, the first magnitude class containing the brightest stars.
The parsec (symbol: pc) is a unit of length used to measure the large distances to astronomical objects outside the Solar System. A parsec is obtained by the use of parallax and trigonometry, and is defined as the distance at which one astronomical unit subtends an angle of one arcsecond (13600 of a degree).
