Light echoes around RS Puppis
This time-lapse video uses observations from the NASA/ESA Hubble Space Telescope over a number of weeks to show the variable star RS Puppis and its environment. A stunning example of a phenomenon known as a light echo can be seen around the star, creating the illusion of gas clouds expanding out from RS Puppis.
The observations were taken between over a period of five weeks in 2010, and capture the variable star at different stages in its roughly 41-day cycle. The short video is repeated several times to emphasise the light echo mechanism more clearly.

Brightest and fastest-growing: Astronomers identify record-breaking quasar
Using the European Southern Observatory's (ESO) Very Large Telescope (VLT), astronomers have characterized a bright quasar, finding it to be not only the brightest of its kind but also the most luminous object ever observed. Quasars are the bright cores of distant galaxies, and supermassive...
Saturn and Mercury both behind the sun today
Saturn and Mercury will be in superior conjunction. That is, they will both be in line with Earth on the far side of the sun. Unlike some other conjunctions, this won’t be visible in Earth’s sky due to the brightness of the sun. But we can see this event if we take a look at the imagery from the SOHO spacecraft’s LASCO C3 instrument. Check it out in the video; Mercury is coming in from the solar west (right), and Saturn from the solar east (left). Though Saturn has a diameter more than 20 times that of Mercury, it’s so much further away from us that it appears the smaller and dimmer of the two. Conjunctions really put things in perspective!

A ‘new star’ from a nova outburst is expected soon

▪︎ A famous, distant variable star called T Coronae Borealis is predicted to become visible to the unaided eye in 2024.
▪︎ It could be a once-in-a-lifetime viewing opportunity to view the star, since it waxes in brightness – becoming visible in our skies as a nova or “new” star – only about every 80 years.
▪︎ This star last erupted in 1946. And astronomers believe it will do so again between February and September 2024. Find its constellation now. Then prepare to be amazed when the “new” star, or nova, pops into view.
A nova could trigger a new star soon
T Coronae Borealis, or T CrB, is located 3,000 light-years away from Earth. It is a recurring nova with outbursts about every 80 years. Its last outburst was in 1946, and astronomers believe another will occur between February and September 2024.The star system, normally magnitude +10, is far too dim to see with the unaided eye. After the nova occurs, it will jump to around magnitude +2. That is roughly the same brightness to the North Star, Polaris.
Once its brightness peaks, it should be visible to the unaided eye for several days and just over a week with binoculars before it dims again, possibly for another 80 years.

Just when is the first of the year …
I watch the first of the year in several countries, notably the first of the year on the Gregorian calendar which much of the world recognizes, another is the Chinese first of the year that happened on February 10 this year on the Gregorian calendar. I’m sure that others have noticed this but the new year in old and ancient times was not this way, it started much later, here is a quote …
‘The oldest recorded new year festivities date back to 2000 B.C. in ancient Mesopotamia, where Iraq is now. Called akitu, the festival, which could last for up to 12 days, started on the day of the first new moon after the spring equinox—the day when sunlight and darkness are equally long. It usually fell around March.’
This make sense to me, the first of the year is typically a party, not that I mind partying in the middle of winter, but springtime seems to me to be a better time to have a party, especially in olden times, much warmer than the middle of winter when you are trying to wrap up to keep warm. Another quote for you …
‘During the spring equinox, the Earth's axis and its orbit line up so that both hemispheres get an equal amount of sunlight. The word equinox comes from two Latin words meaning equal and night.’
This year March 19 was the spring equinox, the new moon in March was on March 10 which is before the equinox. That makes the next new moon happening on April 9 is this new moon this year.
Goodness, this makes the first day of the ancient Mesopotamian exactly on the same day we are having a eclipse. Now the C’s have stated ‘After the first of the year’ in the transcripts, is this the first of the year that they are talking about. Coincidence comes to mind, you make the call. As for me, I will be watching …
And since I have your attention, here are the planetary positions for this date. One thing to note is that when Venus swings around next year around this time and comes close to Earth, we will be near Mars. Could be a nice alignment then. (Source: Solar System Live (fourmilab.ch) Here are the plots for April 9th this year …
Now bear with me as I go a little out of the box here, this is from Pierre’s understanding of the solar system.
You as a person have a home or a location that you call your birthplace, you have a connection to it in varied ways. Now I relate this to the slaves that were stolen from their homes in Africa, do you think that they forgot their homes, you better believe they didn’t, they still have a connection to their homes even throughout the generations.
Now I am lucky as I am still in the place I call home from one year old and I find a connection here, unfortunately it is not my birthplace. I have been back to my birthplace, I see no connection to it.
Now Pierre came up with the theory that Venus as a comet caused a bit of distress in our solar system. In his theory, Venus stole quite a bit of material from Mars and deposited it here on Earth through cataclysmic events. This material that we received from Mars, mostly water, has a soul and I would expect that it still remembers it’s home. And as we get close to Mars, it calls out to this material and may call it to come home, a physical impossibility but I still believe there a connection as we get near it.
Now it just happens that we will be swinging around the sun and by each other sometime later this year and lasting for months after that. This time next year we will be past it. but during this time I believe that Mars will be calling its material home, not that it will happen, as I said it is a physical impossibility. But what if this material feels this pressure and rebels? Just think on this as we move further into this year.
Ta Ta for now and hold onto your britches, it could be a roller coaster ride starting with this Eclipse next month. Haiku …

Why would this coming Mars transit close to Earth next year be any different than all the others before? It happens about every 3 years that Earth and Mars pass close to each other.

Quote:
'Every 2.4 million years, Mars's orbit comes close enough to Earth that its gravity can affect it, tilting Earth's usual path and orientation. This orbital shift causes Earth to be exposed to more sunlight, warming the climate, which, in turn, stirs up ocean currents and makes them stronger.'
Yes, but now it is being noticed, here are a few stories of this.

SPIRALING COMET: Shapeshifting Comet 12P/Pons-Brooks has been a devil, ,a Romulan Warbird, a Millennium Falcon--and now it's a lawn sprinkler. Michael Jaeger photographed the comet's spiralling core from his backyard observatory in Martinsberg, Austria:
Jaeger assembled this movie from a series of pictures he took during the first week of March. Researchers believe that an "ice geyser" on the comet's surface erupted Feb 29th, spewing a reflective plume of space-cold gas and dust into comet's atmosphere. Jaeger's animation shows that plume bent into a spiral shape by the spin of the comet's core.
Comet 12P is currently located in the constellation Pisces, about 15 degrees above the western horizon after sunset for most observers in the northern hemisphere. Shining as brightly as a 5th magnitude star, it is a relatively easy target for backyard telescopes.
Tthe comet will be fairly close to the sun during the total solar eclipse of April 8, 2024.
Dr C. Alex Young said:
No matter how many minutes totality lasts, it will feel like it’s flying by. So drink up as much of the view as you can. Whether you want to tear your eyes away from the eclipsed sun to look around is up to you. During the total eclipse, when the sky darkens, you’ll see the brightest planet Venus pop into view on one side of the sun. On the other side of the sun, you’ll find the second-brightest planet, Jupiter. And if Comet Pons-Brooks is bright enough, you’ll see it between Jupiter and the sun, but closer to Jupiter.
So "the devil" and "the god" will be together to witness the eclipse.

I thought the
State of Emergency in some states/counties at US due the next Eclipse was exagerating much. As if is the only one for ever happening.
In Mexico, some states are going to cancel classes, I suppose it is understandable that way every parent can prevent their children from looking directly at the sun. My sister is thinking of not sending her son to school because of that precisely.
But... But? Changing path a week before?, I thought I fall in some sort of April's Fool thingy, it turns out that some media are saying just that.

Does anyone knows him or are aware of this path change?
I find it weird? I mean shouldn't we had known about the radious of de Sun before? I would remember, I think?
This year is shaping up to be the year of disbelief and confusion, I have had several already.
