Pioneer cover

From the press release: From the moment he is handed a possibility of making the first alien contact, Saunders Maxwell decides he will do it, even if doing so takes him through hell and back.

 
Unfortunately, that is exactly where that journey takes him.

 
The vision that Zimmerman paints of vibrant human colonies on the Moon, Mars, the asteroids, and beyond, indomitably fighting the harsh lifeless environment of space to build new societies, captures perfectly the emerging space race we see today.


He also captures in Pioneer the heart of the human spirit, willing to push forward no matter the odds, no matter the cost. It is that spirit that will make the exploration of the heavens possible, forever, into the never-ending future.

 
Available everywhere for $3.99 (before discount) at amazon, Barnes & Noble, all ebook vendors, or direct from the ebook publisher, ebookit.
 

Betelguese fades a full magnitude

Long term observations of the red giant star Betelguese have found it to have faded a full magnitude in the past few months, dropping it from 6th brightest in the sky to the 21st.

You will see a lot of bad journalism related to this story, hyping the fact that Betelguese is considered one of the top nearby stars to someday in the far future go supernovae. However, the recent change in brightness is unlikely related to this and is nothing unusual, as the star fluctuates regularly.

The current faintness of Betelgeuse appears to arise from the coincidence of the star being near the minimum light of the ~5.9-yr light-cycle as well as near, the deeper than usual, minimum of the ~425-d period.

The star is definitely interesting, because it is so large (if placed in our solar system its surface would be around the orbit of Jupiter) and so defuse, more like a partly filled gasbag. However, the odds of it going supernovae in the near future is quite unlikely.

    Thanks for the critique!

    Clearly, the dimming was actually caused by the smoke from the attack ships on fire off the shoulder of Orion. This is 2019 after all!

  • David – nice!

    I thought the ‘bad journalism’ might be stories that Betelguese is an ‘indicator star’, and a warning that humans are harming the galaxy.

  • Ken

    David, very nice!

    Blair Ivey, it’s likely related to retreating glaciers /sarc

    David–
    excellent cultural reference!

    The stars are going out.

    One factual question: As Betelguese dims, is it also getting redder? This would not be atypical, but I have not seen any
    discussion of this.

    I first read the “Nine Billion Names of God” as a teenager and it knocked my socks off as I discovered that Science Fiction was more than Space Opera. Further in the paperback was “The Star” – which I consider the most horrifying Christmas Story of all time. The combination caused JBS Haldane to tell him that if he had been more consistent in his religious views as expressed in his stories, he would have been a serious public menace.

    The constellation of Orion is my favourite, and spectacular here in the winter, in a reasonable dark area the nebula is clearly visible with the naked eye.
    Unfortunately so far this winter the sky has been overcast every time I have been outside in the evening, but when we finally get a clear sky it will be interesting to see if the dimming is noticeable… I actually hope so.. of course we see the planets change position, and the phases of the moon etc… But to see with the naked eye another star change would be kinda cool.
    ( And if course we should all keep fingers crossed it does go Nova… Then I could show my daughter what she is named after…)

    Lee,

    Learn to find the star Algol (Beta Persei) in the constellation of Perseus. It is an eclipsing binary star with an orbital period of 2.86 days. It’s not hard to find predictions for the middle of the eclipse when the star is a little more than 2.5 times fainter than when it isn’t in eclipse. There’s a star near it which is about the same brightness as when Algol is in maximum eclipse so it’s easy to tell when Algol is normal brightness or not. The difference is quite striking even to the naked eye. It’s been called the Demon Star for thousands of years.

    @ Paul Sventek, thank you my friend!!! I’m mostly into planetary viewing.. I only have a hodgepodge 4″ refractor built from a Soviet era extremely huge telescopic photo lens, an interesting combination of prisms and some old microscope lenses… But it works…
    Now I have something extra solar to get excited about, and a project for the kids to at the very least get kudos in science about!!
    A very good year to you my friend… And thank you once more!!!

  • pzatchok

    Its another one of those extra-terrestrial constructs that blocks out some of the light coming from a few stars.

    They are building fleets. Fleets the size of solar systems.

    Or someone forgot to pay the power bill.
