Question: When was the star in Draco that is visible primarily in the northern hemisphere discovered? Passage:Like the star Epsilon Draconis in the constellation of Draco, Beta Cephei is visible primarily in the northern hemisphere, given its extreme northern declination of 70 degrees and 34 minutes. It is nevertheless visible to most observers throughout the world reaching as far south as cities like Harare in Zimbabwe, Santa Cruz de la Sierra in Bolivia or other settlements north 19South latitude. It is circumpolar throughout all of Europe, northern Asia, and North American cities as far south as Guadalajara in west central Mexico. All other locations around the globe having a latitude greater than 20North will notice that the star is always visible in the night sky. Because Beta Cephei is a faint third magnitude star, it may be difficult to identify in most light polluted cities, though in rural locations the star should be easily observable.

Question: When was the country that was represented particularly well in the hip hop movement founded? Passage:Latinos, particularly Puerto Ricans, were at the forefront of the hip hop movement, however; they have often been forgotten in conversation. Nonetheless, we can see the presence and influence of Latinos in hip hop when we think about artist like: Africa Bambaataa & the members of the Zulu Nation (1960s), Latino DJ, DJ Disco Wiz (aka first Latino DJ in hip hop) & DJ Grandmaster Caz came together to form the Mighty Force (1974), DJ Charlie Chase of the Cold Crush Brothers (1975), Lee Quinones & Lady Pink (1970s), and various others have allowed for Latinos to have a part in hip hop culture and hip hop history. Latina's also had a huge role in hip hop, women who were not on the hip hop stage take part in: the influence and making of music and hip hop performance, dancing of music, and graffiti art. Today we see Latinas like: La Caballota aka Ivy Queen (1995), Ana Bijoux (1995), Angie Martinez: "The Voice of New York" (1996), Hurricane G aka Gloria Rodriguez (1997), Mala Rodriguez (1990s), Lisa M: "The Queen of Spanish Rap" (1988), Nina Dioz (2009), Snow Tha Product aka Claudia Feliciano (2011), Melony Redondo: MelyMel (2018) have been women who have all taken the stage and made their mark as Latina and Afro-Latina rappers/artist in the hip hop world.

Question: What other comic book series did the person who penciled issue #18 of marvel Super-Heroes work on? Passage:Vance Astro first appeared as a founding member of the Guardians of the Galaxy. According to Roy Thomas, all of the Guardians of the Galaxy were created in a conference between Arnold Drake and Stan Lee, but it remains uncertain whether each individual character was created by Drake, Lee, or both. The Guardians of the Galaxy debuted in the partial reprint title Marvel Super-Heroes with issue #18 (Jan. 1969), written by Drake and penciled by Gene Colan. After five years' absence, he was revived in several Marvel titles: Marvel Two-In-One #4-5 (July-Sept. 1974), Giant Size Defenders #5, and Defenders #26-29 (July-Nov. 1975). In each case, other heroes such as Captain America, the Thing, and the Defenders aid Astro and the Guardians against the alien Badoon. The first story established that if Vance Astro's containment suit were breached, he would age 1,000 years in a second. This drew numerous queries from readers, and the letters page in Marvel Two-in-One #7 responded by stating that Vance feeds and defecates intravenously. The Guardians were also featured in Marvel Presents #3-12 (Feb. 1976 - Aug. 1977).
