The best time of year to observe the stars and deep sky objects in Gemini is during the month of February, when the constellation is prominent in the evening sky. This courseware module is offered as part of the Repository of Open and Affordable Materials at Penn State.. The presence of this field suggests that Pollux was once an Ap star with a much stronger magnetic field. In Greek mythology, Pollux was one of two brothers who appeared prominently among Jasons Argonauts. The stars spectrum served as one of the stable anchor points by which other stars were classified. Plus, at only 240 light-years away, Spica would put on a display, possibly brighter than a full Moon. "It will depend on whether what remains on the inside is an active pulsar, a very. In the simplest terms, that means its going to explode in an extremely dramatic way, easily visible from Earth. Letter N represents the North Pole. The list includes massive WolfRayet stars, which may become Type Ib/Ic supernovae. Pollux lies at a distance of 33.78 light years from Earth. 25.
