Fragments Of Comet C/2019 Y4 (ATLAS) Start To Brighten, Per Ace Comet Hunter Terry Lovejoy.

The first set of imaging is by veteran comet hunter Terry Lovejoy — who has discovered 6 comets. He knows his stuff & his forte is astrophotography. His pictures show that one fragment has brightened noticeably. This could be because it is getting ever closer to the Sun and as such continuing to become more ‘active’ — i.e., ‘evaporate’ giving out gases.

The comet has definitely fragmented. Of that there is no doubt or debate. The ‘orange’ Hubble picture shows 4-fragments and JPL (2nd image) already lists 5.

As the orbital diagram shows the ‘comet’ — or to be more precise — the fragments are still a longways out and we are moving away.

The fragments may be bright, but they are SMALL. So naked-eye visibility is questionable.

Hubble Imaging Shows Comet C/2019 Y4 (ATLAS), Alas, Continuing To Fragment.

C/2019 Y4 (ATLAS), as I told you last week, has started to fragment.


Some very clear & graphic imaging on C/2019 Y4 (ATLAS) from Hubble.

You can clearly see that it continues to break-up. It will NOT be naked-eye visible. SORRY.

Hopefully C/2020 F8 (SWAN) will step in. I am keeping an eye — quite literally.

Think – Today: Why Is The U.S. Presidential Inauguration Always On January 20, Irrespective Of The Day Of Week?

by Anura Guruge


thinktodaybanner
bill_clintonThe next one will be, rain or shine, and whether it falls on a Sunday or Wednesday, on January 20, 2017. Why is it always (as far as you can remember) always on January 20? Why?


Think first, then research, then THINK again. Think for the pleasure of thinking.


Yesterday’s ‘Think’: “Famous early 20th century scientists and Google” — We will never know the answer, one way or another. All we can do is speculate, and there are pros and cons (so to speak). Some of these famous scientists, Einstein for one, were original thinkers. They didn’t rely too much upon prior work done by others. By that was not an absolute. At some point in their life they must have done some research to get to where they were — and Google could have helped. There is also the matter that, ‘then’ compared to now, there wasn’t as much of a body of prior work that they could have called upon — with or without Google. But it is also true that there were numerous situations where a scientist would spend years solving a problem only discover that somebody else had already solved it unbeknownst to them! Google could have minimized that. It is also the case that scientists were sometimes totally unaware of germane published work done by their contemporaries. It is claimed that Hubble (the famed cosmologist) went for years without being aware of Einstein’s work. Google could have helped. So, we will never know. Then there is the matter that Google can be a huge distraction and thus a potential time-waster! On balance, though, it might be safe to say that Google probably could have helped these famous scientists.

Comet ISON prospects, quite literally, are getting brighter by the day.

It is intact and is becoming more ‘active’, i.e., spewing out more gas and dust which is what leads to the coma and tail, by the minute.

Right now it is travelling at more than 10 miles PER SECOND. That is in excess of 38,000 miles per hours. So it is getting closer to the Sun at a very fast clip.

Ameteur astronomers using backyard telescopes are capturing some amazing pictures. Check this one from October 5, from Austria (that is in Europe).

On November 2, 2013, i.e., next week, it will cross Earth’s orbit for the first time, i.e., inbound (towards Sun) crossing. Check this post for orbital diagram.

But, on that day Earth is way off to the right — 112 MILLION miles away, that is 1.2 x the Earth-Sun distance.

So, we will not be able to see Comet ISON, naked eye, on November 2.

The EARLIEST possibility for a potential glimpse is November 17 — some of this also having to do with moonlight getting in the way.

Closer to the 17th, as things become more clear, I will post an update.

Enjoy.

It might not be the ‘Comet of the Century’, but it is still on track to be one heck of a comet.

 

 

Comet ISON, C/2012 S1, Looking Very Promising As It Hurtles Towards The Sun; Naked Eye Visible In A Few Weeks.

Looking good. Very promising. I am still very hopeful.

I never lost faith. I knew that the naysayers where just seeking their 15 minutes of publicity.

Should be naked eye visible by the November 10, 2013, I reckon.

Judging by my book sales curiosity is piquing if not peaking.

I am doing presentations on ISON at the Taylor Community (in Laconia) and at the Alton Public Library during the first week in November. I will post more details soon. So, if you are interested, come to one of those. Would love to see you. I am also speaking at Portsmouth Rotary, but that is after Thanksgiving.
