... October 4, 1995 . The Sun Spews X-rays . Credit: Yohkoh Soft X-ray Telescope , ISAS , Japan . Explanation: Our Sun is really very hot. The Sun's outer atmosphere is so hot that it emits much light in the X-ray band, which was unexpected. X-rays are usually emitted from objects having a temperature in the millions of degrees, not the mere thousands of degrees of the Sun's surface. The above X-ray picture shows the Sun one particularly active day in August of 1992. ...

DISCLAIMER: The larger the aperture, the more light a telescope will gather and the fainter the object you can see. Here is a range of magnitudes you might expect to see. Given excellent sky conditions and good optics, a well trained eye can sometimes add up to 0.8 magnitude to these values. Limiting Magnitude depends on much more than the instruments aperture. ... One formula is for aperture in inches the other is for aperture in millimeters. ... Aperture (inches) . ... 15.2 . ...

The first stars, known as Population III, produced the first heavy elements, thereby enriching their surrounding pristine gas. However, all previous detections of metals in intergalactic gas clouds find a heavy element enrichment at least 1/1000 times that of the solar environment, which is higher than expected for remnants of Population III stars. ... Finally, I will summarise the prospects for finding similar systems in future surveys. ...

... We compare our results with the GRANAT X-ray observations of the Galactic center (Churazov et al. ... It is instructive to compare our results for the Galactic center starburst with what might be expected for a continuous star formation, with the average rate characteristic for the whole Galaxy. For this continuous star formation model, we would expect to observe in the region of around the Galactic center about 10% of the total number of X-ray sources in the Galaxy. ...
