Twin Black Holes inside a single star - how weird is that?!

Two weeks ago I reported what could very well be the greatest 'history making' discovery in the past 100 years - the evidence of Gravitational Waves.  These waves, produced by the merger of two massive black holes, were detected by the Laser Interferometer Gravitational-wave Observatory (LIGO) instrument in September. Now it appears that the two black holes might have resided inside a single, massive star whose death generated the gamma-ray burst.

Twin comets approach closely in March

Some of you might already know that one of my favorite activities as an amateur astronomer is to image comets.  Well, just found out that not one, but two new comets are heading our way.  Unfortunately they will be very difficult (probably impossible) to see with the naked eye.  No matter, I'll be out as soon as I get a chance and conditions are right and capture these beauties.  Probably won't make for a fancy picture, but just the fact that I caught them in an image against a starfield is good enough for me.

Details can be found at EarthSky.

Won't this weather ever clear?

Well I'm still waiting for a run of clear skies, preferably without the near full moon in the way.  The only two nights that were favorable a week or so ago I was sick, or had other plans.

On the night of February 11th - 12th I did manage to get the scope setup and start my imaging run for the second of three awards on Astronomy Forums for imaging the Messier objects.  There are 110 of them total (109 by some counts since one may be a duplicate - M101, a spiral galaxy may have been misidentified as another object M102).  The idea behind the awards is to recognize astro imagers success in the field by photographing the whole set of Messier objects.  You get an award for the first 40, then one for the next 40, and finally one for the complete set.  Of course the first 40 is fairly easy as we usually go for the 'low hanging fruit'.  I completed my first 40 last year.

So it was off to image M95 and M96.  M95 is a barred spiral galaxy in the constellation Leo, the lion.  M96 is a nearby galaxy almost in the same field of view of my camera.  I set up the scope to automate the imaging of both galaxies during the night while I, of course, slept, since the next day was a work day.  I had planned to take 30 subs of each object, each one an exposure of 3min. 

When I checked the image capture on the morning of the 12th I discovered that I actually got 60 subs of M95 and none of M96.  After examination of the software logs later that day I noticed I had entered the commands to the scope incorrectly, and alas the issue was not with faulty software, but with faulty human operator :)

Anyway, I did get a pretty good image of M95, and as soon as the skies clear and the moon leaves I'll go for M96 again. 

The object centering function is still not working correctly (and I really believe it is a software or hardware problem this time and not human error) so I had to crop the image a bit.

Rosetta’s lander faces eternal hibernation

Philae ... So long and farewell!

With absolute silence since its last call to mother ship Rosetta back in July, the Philae lander is facing conditions on Comet 67P/Churyumov-Gerasimenko that make it extremely unlikely that it will recover and 'phone home' once more.  But much of the science that was planned was completed, and Philae's landing was still an amazing feat; an accomplishment that made history.

Big News!!! Einstein's gravitational waves 'seen' from black holes

Wow.  About 100 years since Einstein theorized gravitational waves they are finally observed.

Scientists are claiming a stunning discovery in their quest to fully understand gravity.

They have observed the warping of space-time generated by the collision of two black holes more than a billion light-years from Earth.

The international team says the first detection of these gravitational waves will usher in a new era for astronomy.

It is the culmination of decades of searching and could ultimately offer a window on the Big Bang.
The research, by the LIGO Collaboration, has been published today in the journal Physical Review Letters.

Small Asteroid to Pass Close to Earth March 5

A small asteroid that two years ago flew past Earth at a comfortable distance of about 1.3 million miles (2 million kilometers) will safely fly by our planet again in a few weeks, though this time it may be much closer.
During the upcoming March 5 flyby, asteroid 2013 TX68 could fly past Earth as far out as 9 million miles (14 million kilometers) or as close as 11,000 miles (17,000 kilometers).
