Those Two Bright Objects In The Sky Over New Hampshire — One Is Venus, The Other Sirius.

Just got in from walking the dogs. WOW. The night sky is bright and CRISP. Haven’t seen it this vivid in a longtime and I go out, at night, MULTIPLE times, including a 20-minute walk around 11pm.

Sirius was very noticeable below Orion. Sirius, is the Dog Star — the brightest star in the night sky. It is actually brighter than Jupiter. This serious brightness of Sirius is due to two factors: it is relatively nearby and it is big — twice as big as the Sun. It is 8.6 light years away. So what we are seeing now is what Sirius was doing 8 years 7 months ago.

On the other side of Orion, impossible to miss, shining bright is Venus.

A few months ago, the bright light was Jupiter. Now, in March, Jupiter has become a MORNING planet. I do not see anything in the morning sky. I try NOT to wake up much before 8:30am. It is NOT civilized or right to do so earlier. I need my sleep, thank you.

Betelgeuse (In Orion) Has Indeed NOTICEABLY Got Brighter In The Last Few Days.

by Anura Guruge


Click to ENLARGE. Betelgeuse is the ORANGE dot, top left above the three stars making up the belt. You can definitely see that it is orange.

I like Betelgeuse and Rigel — the two brightest stars in Orion, the former above the belt and the latter below.

In the Winter, in New Hampshire, I see Orion in the night sky whenever it is cloudfree.

I have been checking on Betelgeuse. It would be quite something to see a Supernova.

I go out, at night, walking, TWICE a night. So, if it is cloudfree, I can observe the heavens.

I too had noticed that Betelgeuse had got brighter, and more orange, in the last few days.

Then, I started seeing the media reports. So, I was not alone.

Just wanted to keep you in the loop. Go out and look up. It is quite the sight.

What Has Happened Or What Will Happen To Betelgeuse (In Orion) — When It Is 700 Light-Years Away.

As soon as I saw the headline in the U.K. ‘Daily Mail’ I knew it was going to be amusing. To be fair, and to their credit, they did make a decent enough fist of trying to explain the ‘dilemma’.

And what is that ‘dilemma’. When we are talking about stars, including our own Sun, we have to factor in the delay it takes for light from it to reach us. In the case of the Sun it takes 8 minutes and 20 seconds. Has to do with the enormous distances involved and the speed of light (which, though very fast, is only ‘that’ fast). So, if something was to happen to the Sun it would be 8 minutes and 20 seconds before we saw anything. Just the laws of physics.

Betelgeuse is ~640 light years away. That means it takes light from Betelgeuse ~640 years to arrive to us, on Earth.

So, we are seeing Betelgeuse as it was ~640 years ago!

Think about that.

When looking at stars we are always looking way back … into history.

We just have NO, NO, NO WAY of knowing what is happening at Betelgeuse right now.

All we see is what happened ~640 years ago.

So, it is difficult to write about ‘future’ events involving stars. The event might have already happened! We just don’t know.

That is the problem with this article. Betelgeuse could have already exploded — without us knowing.

Think about it. It is cool. SMILE.


P.S., All the stars that make up Orion are not the same distance away from us!

Betelgeuse is much closer than most of the others in that constellation! Something else to think about.

That Bright ‘Star’ Above The Moon Tonight, Over New Hampshire, Is Jupiter. It Was Alongside Yesterday. Looks Like Venus, But It Is Not.

Yes, earlier in the month it was Venus that was close to the Moon.

Now it is Jupiter, because they all move about — nothing stays still up there.

Venus is still around and visible in the Southwest sky, very close to the horizon, but setting BELOW the horizon by 7:30 pm. 5:30 pm, directly SW, is a good time to see Venus.

Enjoy Jupiter. It was spectacular last night — beautiful opposite conjunction with the full Moon. Today it will be above the Moon. While you are at it take a gander at Orion and soak in its grandeur.

The Other Bright ‘Star’ In The Night Sky, Over NH, Is ‘Sirius’, Low To The East, Below Jupiter.

Jupiter, given that it is invariably higher in the sky, will most likely be the bright object that first arouses your curiosity and awe.

If it is later in the night you might see a very bright, burning WHITE star, close to the tree line, maybe even glimpsed through the trees in the East. That would be Sirius, the Dog Star — the brightest star in the night sky. It is actually brighter than Jupiter. This serious brightness of Sirius is due to two factors: it is relatively nearby and it is big — twice as big as the Sun. It is 8.6 light years away. So what we are seeing now, in December 2012, is what Sirius was doing 8 years 7 months ago.

Many never think about this. Light thought it travels fast, still has a speed limit. So if an object is far away, it does take time before light from that object gets to us. Even Sun light takes 8.3 minutes to reach us. The light from Jupiter (i.e., sunlight reflected off Jupiter’s gaseous, yellowish atmosphere) takes nearly 35 minutes to reach us. So in reality when we look up and see Jupiter, we are not actually seeing Jupiter in ‘real time’. We are seeing Jupiter as it was 34.9 minutes ago. Think about that. You can have fun pondering this. ‘Rigel‘, the bright white star that makes up the leg of Orion, is ~860 light years away. So what we are seeing is light that left Rigel 860 years ago. For all we know Rigel could have exploded — supernovaed. It would be 860 years before we would see it.

So the next time you look up at the night sky remember that much of what you are seeing is in time lapse. Light that was there sometime before.
