Chromoscope is a nice toy. Pressing 'L' shows the constellations as guide.

There's a bright X-ray source between Ophiuchus, Libra and Scorpius. In Hydrogen-Alpha there are two circular formations to the right and left of it. Are the latter formed by polar jets from the former, and what is that object?

  • $\begingroup$ I haven't found any info yet, but it looks more like a prominent X-ray source surrounded by a disk that's absorbing the X-rays. I'm guessing that black means no X-rays, but there's so much background noise it's hard to get a baseline. $\endgroup$ – HDE 226868 Dec 2 '14 at 0:28
  • $\begingroup$ Assuming that that thing is a disk, I wouldn't think those formations are related, because they're at odd angles - they're not on the same level as the disk, but they're not coming from the poles, either. They seem to be related to nearby stars - see how they're centered around stars? They're not unique to this object. $\endgroup$ – HDE 226868 Dec 2 '14 at 0:30
  • $\begingroup$ Guess #1: Scorpius X-1. $\endgroup$ – HDE 226868 Dec 2 '14 at 0:38
  • $\begingroup$ @HDE226868 At the huge distance of Scorpius X-1, the three formations can't be related. Please make it an answer, if you're sure ;-) $\endgroup$ – LocalFluff Dec 2 '14 at 0:46
  • $\begingroup$ I'm far from sure. . . I'm fairly certain the formations aren't related, though. $\endgroup$ – HDE 226868 Dec 2 '14 at 0:47

The source is Sco X-1. It is a point source of X-rays.

I'll have get back to you on why it looks that way in chromoscope, but it looks incorrect to me.
