Discussion Overview

The discussion revolves around the exploration of the night sky using Google Sky, specifically focusing on identifying celestial objects near the Moon and the Sun's relationship to constellations. Participants share observations and insights about specific stars and galaxies, as well as the nature of constellations.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant questions what a bright object near the Moon is, leading to a discussion about the star Spica, identified as the brightest star in Virgo.
  • Another participant describes the Sombrero Galaxy, suggesting that it can be found near Spica in the Google Sky image.
  • Some participants note that the Moon's position changes against the stars, which can make it difficult to locate it in the sky image.
  • A question is raised about whether the Sun is considered a star within any constellation.
  • A later reply clarifies that the Sun is not part of a constellation due to its position in the solar system and its changing location relative to the stars.

Areas of Agreement / Disagreement

Participants express differing views on the Sun's relationship to constellations, with some agreeing that it is not part of any constellation while others provide historical context for the concept of constellations.

Contextual Notes

There is a lack of consensus on the classification of the Sun in relation to constellations, and the discussion includes varying interpretations of celestial observations.

I don't see the moon anywhere there, but the google sky image is centered on the bright star Spica -- also "Alpha Virginis"; the brightest star in the constellation of Virgo. It's the 16th brightest star in the sky.

Postscript. Now let's really have fun. There's something else in that google sky image well worth a closer look... a MUCH closer look.

Starting from that sky image, go across to your right. It is at about "12 hr 40min" on the horizontal axis, and -11deg 37' on the vertical scale -- almost aligned with Spica, vertically. There's a star, which might look a bit fuzzy.

Double click on it to zoom in... the impression of fuzzyness should increase.
And again -- definitely something of a blob. Keep clicking; you're in for a treat.

This is the Sombreros galaxy; one of the really beautiful spiral galaxies, with very dusty lanes and a large bright center. Either try finding it yourself starting out from Spica in the link above, or you can jump right there with this link

Thanks -- found it! I guess it is not placed there by default because it keeps moving against the stars.
 
Is sun a star in any constellation?
 
Hi there,

I am not a pro in constellation, but the Sun is not part of or into a constellation.

You have to understand where the idea of constellation comes. When our ancesters were looking at the sky (at night) they thought that it was a roof with stars hanging from it. They also noticed that these stars were "motionless" from one another. Therefore, they thought of arranging and defining the sky from the different shapes the stars were forming. Enough of this history bull crap.

The Sun being part of (and the center) our solar system, it's relative position in the skye will keep on changing compared to the stars. Therefore, the sun will eventually cross the constellation from the ecliptic (for which there are twelve), but that's it.

Cheers
 
thanks...
