Mercury’s Transit Of The Sun As Seen Over New Hampshire — November 11, 2019.

This is what we saw!

The Sun was up there but behind some impressively thick clouds.

I was hoping that we might get a break. No such luck.

Well, I will not be around for the next one so I will never see this phenomenon again. C’est la vie.

But, I at least have seen one transit. Venus transit across the Sun on June 5, 2012.

This is what it should have looked like.

I know. I do know my astronomy. SMILE.

Just for YOU. Smile.

This Latest Interstellar Comet, 2I/Borisov, Is By NO Means The Only Comet To Spew Cyanide Gas. Quite Common!

by Anura Guruge

From ‘Google News’. It was BIG in … astronomy news.

Click to ENLARGE. From my ‘Comets 101’ book. Link below.

Yes, everybody is trying to cash in on this Interstellar Comet — supposedly the second we have discovered (albeit, both in the last 2-years). When I saw the headlines about cyanide it made me smile. I knew that cyanide was not uncommon in comets.

Recall Halley’s comet that comes around every 75-76 years. In the early 20th century there was a scare that folks would die from the cyanide that was emanating from its tail. Well nobody did.

So, please don’t get excited about this cyanide. It will NOT kill you or anybody else.

Has a ton of good information about comets.

Mercury Will Transit The Sun On November 11, 2019 — Remembrance Day, At That.

by Anura Guruge

YOU  will need Eclipse Glasses.

A ‘transit‘ in astronomy is when celestial body passes in front of another. In this case, it will be Mercury passing in front of the Sun — and we, in New England, will have front-row seats for it, and, moreover, it will be in the morning, around 10 am Eastern. The only thing that can spoil it for us is the weather. I will keep you posted.

Given that this is a solar transit, it is kind of like a solar eclipse — like the BIG one we had in August 2017. And as with a solar eclipse you MUST HAVE eclipse glasses IF you are going to look at the Sun. They are cheap enough. Better get some now. I still have mine from 2017.

That it is on Remembrance Day — my Poppy Day — makes it even more special. WOW.

TWO ‘Interstellar Comets’ In Less Than 2-Years — And We Have Never Seen ANY Before?

I will grant that this new comet, C/2019 Q4 (Borisov), does have more of an intriguing orbital path than did C/2017 U1.

But, I am not willing to RUSH to the conclusion that it is interstellar — i.e., it did NOT originate in our own Oort cloud. Still very early days. That it is travelling too fast to be bound to the Sun is interesting.

I was not convinced about A/2017 U1 (ʻOumuamua) being interstellar and now others are joining in. SMILE. I do know some about comets.

All I am saying, for now, is don’t rush to a conclusion. Let’s study this puppy a bit more.

Definitely not going to be GREAT comet. It will be very far from the Sun. Twice as far as the Earth is to the Sun. So, unlikely that it will be very bright or sport a spectacular tail.

Just wanted to keep YOU in the loop. But, stay tuned.

‘Black Moon’ Today, July 31, 2019, & How It Differs From A ‘Blue Moon’.

by Anura Guruge

The Key Difference:

Black Moon has to be a NEW Moon.

Blue Moon has to a FULL Moon.

Other than that they both refer to an ‘EXTRA’ moon in a given ‘month’.

‘Blue Moon‘ can mean one of two things:

1. Second full moon within the same calendar month.

2. Third full moon during an astronomical season that has four full moons; an astronomical season in this context being the 3-month period between an equinox and a solstice, e.g., 3-months between the March Spring Equinox and the June Summer Solstice.

‘Black Moon‘, DITTO, but when it applies to a NEW MOON.

So, it means:

1. Second NEW moon within the same calendar month — as is the case this month, i.e., July 2019.

2. Third NEW moon during an astronomical season that has four full moons; an astronomical season in this context being the 3-month period between an equinox and a solstice, e.g., 3-months between the March Spring Equinox and the June Summer Solstice.

Both are rare events.

Furthermore, today’s Black Moon is a Supermoon — i.e., it is closer to Earth than normal.

Did You Know That ‘AOC’, Alexandria Ocasio-Cortez, Has An Asteroid Named After Her?

by Anura Guruge

Donald Trump will be SO, SO livid IF he ever finds out.

So don’t tell him. OK? Our secret.

23238 Ocasio-Cortez (2000 WU111)

This wasn’t recent either! It was named after her c. 2007 — eleven years ahead of her being elected to the United States House of Representatives.

This is pretty impressive stuff. She got this honor, because as a high school senior (aged 18), from Yorktown High School [Yorktown Heights, New York], in 2007, she won second place in the 2007 ‘Intel International Science and Engineering Fair’ for her microbiology project. Wow.

I really don’t know much about her. Did not even suspect this.

Trump will now want Jupiter renamed after him. But, maybe NOT Jupiter. Mars would be more appropriate and it is a GOOD COLOR match.

The asteroid itself had been discovered in 2000 at the Lincoln Laboratory.

A pretty common or garden asteroid in the asteroid belt. Nothing special. Decent size. Just over a mile across. So, not huge, but not tiny either.

Apollo 11 Rocket Launch Projected Onto Washington Monument For The 50th Anniversary — Must See Video.

by Anura Guruge

This is pretty special. I wanted to make sure that YOU hadn’t missed it.

Quite a few videos, of varying length, on YouTube. Take your pick.

Bravo. I am impressed. I am cool for my tax dollars to be used for this.
