M34 can be resolved with good eyesight but is best viewed using a telescope at low magnifications. IC 348 is a somewhat young open cluster that is still contained within the nebula from which its stars formed. It is located about 1,027 light-years from Earth, is about 2 million years old, [74] and contains many stars with circumstellar disks. [75]
The location of this mythical place may simply be a convention to show that a magically distant chthonic land of myth was intended in the remote past. [35] After Persephone had disappeared, Demeter searched for her all over the earth with Hecate's torches. In most versions, she forbids the earth to produce, or she neglects the earth and, in the ...

An asteroid in our solar system will temporarily block the light of Betelgeuse, one of the brightest stars in the night sky, Monday evening and early Tuesday morning.
In 2016, the International Astronomical Union (IAU) organized a Working Group on Star Names (WGSN) [2] to catalog and standardize proper names for stars. The WGSN's first bulletin, dated July 2016, [3] included a table of 125 stars comprising the first two batches of names approved by the WGSN (on 30 June and 20 July 2016) together with names of stars adopted by the IAU Executive Committee ...
In astronomy, coordinate systems are used for specifying positions of celestial objects (satellites, planets, stars, galaxies, etc.) relative to a given reference frame, based on physical reference points available to a situated observer (e.g. the true horizon and north to an observer on Earth's surface).

Rapidly-rotating 20 M ☉ stars take 9.3 million years to reach the red supergiant stage, while 20 M ☉ stars with slow rotation take only 8.1 million years. [173] These are the best estimates of Betelgeuse's current age, as the time since its zero age main sequence stage is estimated to be 8.0–8.5 million years as a 20 M ☉ star with no ...
Following this pattern, several hypothetical bodies were given names: Vulcan for a planet within the orbit of Mercury; Phaeton for a planet between Mars and Jupiter that was believed to be the precursor of the asteroids; Themis for a moon of Saturn; and Persephone, and several other names, for a trans-Plutonian planet.
