Star - Positions, Magnitude, Classification: Accurate observations of stellar positions are essential to many problems of astronomy. Positions of the brighter stars can be measured very accurately in the equatorial system (the coordinates of which are called right ascension [α, or RA] and declination [δ, or DEC] and are given for some epoch—for example, 1950.0 or, currently, 2000.0).
Question: Part A If you are stargazing at a 30 degree latitude in the northern hemisphere, which of the following stars will be visible all year round? none of the above stars C and B. star D. at a declination of 10 degrees. star C. at a declination of 90 degrees. star A at a declination of 35 degrees star B. at a declination of 75 degrees Submit Request Answer
These stars have typical surface temperatures around 4000 K. As we will see, globular clusters are among the oldest parts of our Milky Way Galaxy. Figure [Math Processing Error] 22.2. 1 Omega Centauri. (a) Located at about 16,000 light-years away, Omega Centauri is the most massive globular cluster in our Galaxy.

The 30th parallel north is a circle of latitude that is 30 degrees north of the Earth's equatorial plane. It stands one-third of the way between the equator and the North Pole and crosses Africa, Asia, the Pacific Ocean, North America and the Atlantic Ocean. The parallel is used in some contexts to delineate Europe or what is associated with the continent of Europe as a southernmost limit, e.g
The Galactic Coordinate system is a longitude-latitude coordinate system that is used to define the positions of objects in space, most commonly objects within our own galaxy. It uses the center of our galaxy as the focal point (i.e., where we consider $(0^{\circ},\:0^{\circ})$), much like we use the position just off Africa as the focal point
The general categories are O, B, A, F, G, K, M, R, N, T, Y, and group stars (and stellar objects) by their temperatures, luminosities, and colors. For example, O- and B-type stars are blue-looking and are generally among the hottest stars – between 30-40,000 Kelvin. A-type stars are blue-white and have temperatures around 9,500 K.
The history of longitude describes the centuries-long effort by astronomers, cartographers and navigators to discover a means of determining the longitude of any given place on Earth. The measurement of longitude is important to both cartography and navigation. In particular, for safe ocean navigation, knowledge of both latitude and longitude
The stars of the night we met. We met under these stars. Under our lucky stars. The moment of our first kiss. The moment I fell in love with you. I thank the stars for you. When we first met. Love you to the moon and back. You are my Sun, my Moon, and all my stars.

Apparent magnitude: -0.30; Surface Temperature: 4286±30[7] K; Coordinates: 14h 15m 39s RA, +19° 10′ 56” DE; Arcturus The Red Giant . Arcturus is an evolved and aging red giant star that is 25 times larger than our sun. Since the energy of this star is spread across such a large surface area, the surface temperature is generally cooler.
Get the coordinates of a place. On your computer, open Google Maps . Right-click the place or area on the map. This will open a pop-up window. You can find your latitude and longitude in decimal format at the top. To copy the coordinates automatically, left click on the latitude and longitude.
The rate of motion is steady, so simple multiplication or division allows us to calculate the angle for any other time period: 5° in 20 minutes, 7.5° in 30 minutes, 15° in an hour. Over a full 24-hour day, the angle of rotation would be. 15° × 24 = 360°. The stars therefore complete a full circle (360°) in 24 hours.
The map below shows if you are located on the high, the middle, or the low latitudes. We can conclude that the middle latitudes need a Kp-index from about 4 to 7 depending on where you are. Belgium for example which is on the middle latitudes but close the lower latitudes would need a Kp-index of 7 for aurora on the horizon.
