I'm using the Revolution Imager to generate video frames and stacking them real-time with SharpCap for viewing at the 'scope. It was discovered in 2008 and was announced at the time. Something is odd here. So why are there so many blue stars in this picture? The habitable zone for Alpha Centauri B would be a little bit closer to the star, at roughly 0.7 astronomical units, or 100 million kilometres, which is about the same distance as that between the Sun and Venus. To give idea of size, the Sun is 99.86% the mass of the solar system. and he'll do it without the high-class devils even realizing it. Seeming to belong to two constellations at the same time, poor 10 UMa is the victim of shifting constellation boundaries. Also known as the Needle Galaxy for its narrow profile, bright NGC 4565 is a stop on many telescopic tours of the northern sky, in the faint but well-groomed constellation Coma Berenices. High-resolution, high signal-to-noise spectroscopic observations at H-alpha of the helium-weak star 36 Lyncis (HD 79158) confirm the lack of emission and lack of line asymmetry reported earlier . It is a periodically conspicuous reddish object in the night sky. As the sun ages and grows hotter there is a simple method (besides carbon nanotube sunscreens) to address the issuee.
