Now that Spring has sprung, which is up for debate. Our temps here in Vermont have been up and down this week. On Monday, we had sunny skies,and high temps near 80 degrees F. By Wednesday,those temps were seemingly a long ago memory,with high temps of 32 Degrees F. Might I also add that we had received 1″ of fresh snow,and a low Wednesday morning of 16 degrees. Note: Our temps have rebounded and is now a balmy 48 degrees. Sorry, that was just a little bit of venting!. Ok,back to the post. As everyone knows, Mars is putting on quite a show in the early evenings,and with clear skies is not disappointing. I have imaged every planet in our solar system over the years,and most have been easy imaging except for one. That’s right…… Mars!. It seems that the Roman God of war doesn’t like it photo taken!. I have made attempts many times,with the same results. The fuzzy blob blues!. Being in a climate that is transitioning from Winter to Spring, having clear,clean skies is a novelty. Last night was just that novelty,even for a short period of time. I stepped out early last night,and noticed clearing skies. ...

For the first time, astronomers have seen a double star brighten rather than fade when one star passes in front of its companion. Predicted decades ago, the phenomenon arises from gravitational microlensing as the great surface gravity of a white-dwarf star magnifies its partner's light. The discovery by US researchers raises the hope that we will someday catch a neutron star or black hole doing the same thing, which would lend new insight into these extreme objects. Many star systems are double, having two stars that orbit each other. In some cases, the orbit aligns edge-on to our line of sight, so that one star periodically eclipses the other and dims the light that we see. Astronomers have known of these eclipsing binaries for centuries. The best example is Algol – Arabic for "the ghoul" – which medieval astrologers considered to be the most dangerous star in the sky, probably because they knew that its light flickers. In 1782 British astronomer Edward Pigott correctly explained why Algol dims.It was not unitl 1973 that Swiss astronomer André Maeder predicted that some binaries should exhibit the opposite phenomenon. According to both Newton's theory of gravity and Einstein's general theory of relativity, mass ...

Question: I can’t get seem to find a thoughtful yet scientific answer to this question, I was hoping you could help. I hope this doesn’t sound dumb, I don’t mean it to be. When we look at the night sky, we see a blanket of stars. They seem very close together and crowed in the sky. I know some of them may not even still exist, just the light still coming from them over millions of light years away, in some cases. But how is it that we can see stars that appear to be so close together but in fact are at least light years away from one another, with the naked eye from earth, no less? And stars from one side of the night time horizon to the other have to be billions of light years apart, right? How can we see objects so far away with the naked eye? If we use our suns size and scale it to stars we see in the sky, millions of light years away we should not be able to see them at all, right? I just don’t get it! Is there some phenomenon I’m not understanding? – Tim Answer: For ...
