Eclipse Definition and 123 Threads

hello : i am reviewing my undergraduate physics classes , during my free time , taking a look on CS106 from stanford programming mythology , but i dont know how to use the eclips program , for example when i write a code using that provided in the course , the libraries seems missing from...

Once decades ago I watched a movie where solar eclipse made a woman vanished standing in a tree. Then she appeared during the next solar eclipse. Anyone remember the title of the movie? I'd like to watch any solar eclipse movie where portals were opened during the eclipse. Do you have any in...

We can: 0) watch the eclipse unfold with our ISO approved eclipse glasses 1) listen for insects chirping as they think night has fallen 2) make a pinhole camera from a shoe box 3) wear red and green clothing to see how our perception changes in the twilight of the eclipse (to witness the...

I want to write a story about a planet that has yearlong eclipse that how its natives and ecology adapt to this celestial condition. I am just wondering how realistic/feasible it is for some planet to have a moon in stable orbit producing eclipse for 1-3 years, every 70-100 years.

I got myself some glasses for the upcoming solar eclipse, but they are very dark! They work fine for looking at the Sun in all its glory, but I suspect I won't ne able to see anything of interest during the eclipse. Does anyone have experience filtering out the harmful UV while still being...

The upcoming conjunction of Jupiter & Saturn has got me thinking. I wonder if it has ever been observed (and hopefully photographed) of one planet's disc even partially taking over another's. I have seen a photo of Saturn doing this with the Moon, but I don't think I've ever seen one of a pair...

would spectators be able to see it? How about with 12X binoculars? https://www.nytimes.com/2020/09/15/science/sun-solar-cycle.html

Hypothetical: Approximately how far from Earth would a star the size of the sun have to be for an object the size of a quantum particle to cause a total eclipse of that star when orbiting the Earth at a distance equal to that of Earth to the center fro the moon?

This might be total nonsense, but the thought popped into my head while I was trying to get to sleep, so I thought I see if I could find any advanced help with the following hypothetical: If light were instantaneous, how far from Earth would the sun have to be to cause a quark orbiting in place...

Was there a published report of exactly which stars which were supposed to be at position A but were observed at position B, etc.?

Is the reason you can make out the shape of the sun and the moon is because the gaps between the leaves cause the light to be photons instead of waves?

There will be a solar eclipse on 26th December that can be viewed from my city. In addition to buying safety glasses, I also want to prepare my camera, if possible. The camera is a Panasonic FZ-70. I have a UV protector and four ND filters - 2, 4, 8, 16. I am also buying a circular polarizer...

There is the famous experiment of measuring the "movement" of a star close to the sun during an eclipse. The stars position is determined before the disc of the sun moves just under it and than the position is again measured when the sun moves just "under" the star. The star will have appeared...

From my understanding, for an observer to see a total solar eclipse, 1) the Moon's orbit has to be near aligned with the Earth's Orbit, 2)such that the New moon's Umbra falls on Earth, and 3) the observer must be within this cast umbra. But for a partial solar eclipse, since the Penumbra of the...

This is my understanding.

I see that South America (Chile/Argentina) will be getting a total solar eclipse this winter (i.e., winter there) and then another one only 17 months later that seems to be along the same type of path, albeit a little bit south. This can't be very common...

Sirius, the brightest star in the sky, might be eclipsed by an asteroid in a few days: https://www.skyandtelescope.com/observing/will-sirius-disappear/ Can a 7-kilometer-wide asteroid make Sirius disappear? You bet it can. That just might happen on Monday night, February 18th. That evening...

(For reference, I am around coordinates ( +30 , -90 ), and this is the January 2019 lunar eclipse.) I am typing this at supposedly mid-eclipse, and yet I see a thin crescent of white (ash?) along one side. It seems that the Moon should be well within the umbra at this point.

Anyone else watching the lunar eclipse tonight? It starts at about 9:30PM EST, with totality at 11:41. It's cold and windy in PA, but at least it's mostly clear. Here's a couple of pre-eclipse photos:

Dear All Concerns Black Hole is formed at the end of life of a big star. The mass of such star should be equal to 5-10 solar masses. But I am imaging very small moving black hole coming to our solar system and passing between our Earth planet and the sun thereby creating solar eclipse of unique...

It seems that a partial solar eclipse is one in which the eclipse circle never completely rises, and it essentially is only a sunrise or sunset eclipse, with the point at which it goes from sunrise to sunset being that location in the polar region where the eclipse is at "high noon" but which it...

Can total lunar eclipse and partial lunar eclipse be happened at the same time? So, do we call it partial lunar eclipse when the total lunar eclipse happen just before?

Hello, I don't see any other post about tonight's full moon and lunar eclipse, so I thought I would mention it.

Did the 2017 eclipse prove Einstein was right or the jury is still out? I can't find any references to the new measurements and what they proved (or did not).

What can we learn from a solar eclipse that the NASA IRIS program doesn't tell us? (and why)

I observed the eclipse from Washington DC area yesterday. I have a few questions. from the eclipse map and youtube clips ppl uploaded, the eclipse starts in Oregon and sweep across states. questions: 1. I know Earth rotate around itself from west towards east every 24 hrs, is this the main...

Why didn't the Earth get dark? Apparently, even in a total eclipse the moon doesn't block out the total circumference of the sun. Is it a matter of geometry?

Hi there, I've watched this video: . I have been curious the whole day why the eclipse path seems to be curved and obviously in our latitude. Is it because of both the moon's orbital plane and the tilt of the Earth's axis? If it went across the US, that is a lot more than 5 degrees (moon...

How accurate do you think NASA's eclipse calculations are? Will that aircraft provide accurate moon trajectory?

Hello MHB Community! :D As I'm sure most of you who live in the U.S. are aware, we will be witness to a solar eclipse on the 21st of August and the path of totality will cut across the continental U.S.: I live in NE Florida, and will experience almost 90% obscurity, but I have family in TN...

How long does it take for the temperature on Earth to cool down after the sun has set? I want to know if the total solar eclipse will change the temperature.

I am from Michigan, I read about the August 2017 eclipse and it's not passing through my home state. I was wondering, is there any formula or even just general common sense that will say if their will ever be a Eclipse in Michigan? I don't care if it's a solar OR lunar eclipse. Will there be an...

I think I may be heading to Makanda Illinois, on August 21, for the Eclipse. (Where I live in Michigan, it will only be about 80% - I want the full effect...) In all likelihood, considering my age, and how mobile I may be by the next time there is a full eclipse in the US, I have decided I...

Dear group, I am using Eclipse in the Ubuntu operation system and trying to print out this data from the begin to the string "END OF HEADER" but I do not understand why it did not give me the one as I expected. I also used this file "albe0320_1.17n" to test and it worked, but the file that I...

during solar eclipse , moon's shadow on Earth is almost a point [267 km which is a 0.00000523 % of Earth's surface area] which means that sun light must bend, if it is not bending then we would never get a point shadow of moon on earth. now the question arises why sun light bends, is it a...

I've been waiting for this for a long time and it's just a little more than a year away now. This will be the opportunity of a lifetime for people in the U.S. The 2017 solar eclipse will be visible across the width of the entire U.S! The points of Greatest Eclipse and Greatest Duration are...

Dear all, I have been reading through this article about how often different types of eclipse (eclipse cycles) can occur. I'm presuming that all fictional eclipses have to be variations of these? Even with a fictional planet/moon/solar system? But what if the desired recurrence of an eclipse...

Below is the link to the Lunar super eclipse Sept. 27th. It won't happen again until 2033. http://finance.yahoo.com/news/theres-rare-supermoon-total-lunar-205421688.html?amp;soc_trk=ma&soc_src=mail&soc_trk=ma

Hi, Just wondering: The lunar orbit around the Earth is tilted 5.1 degree with respect to the Earth's orbit around the sun (as described in the video), so only at 2 times during the year the Earth is aligned with the sun such that lunar eclipses can happen IF the moon is behind the Earth...

I was wondering whether there is an actual scientific point of taking ground-based photographs of the Solar corona during total eclipses on Earth. It seems to attract a lot of attention from well equipped amateurs around the world and the pictures of the fine plasma structure surely look great...

Just to let everyone know here in the UK we are waiting expectantly for the Solar Eclipse tomorrow morning - max at around 9.30am. 98% coverage in the north of Scotland and the Orkneys, Hebrides and Shetland islands, 85% down here in the south. The totality shadow crosses from the North...

If solar eclipse occurs at 12h 12m 12s actually. Then at what time one will see it on earth. Will the speed of light affect the time if moon starts covering sun at 12 h 12 m 12s when one will see covering on earth? at what time? I just want to know I am just curious do you think the time taken...

Homework Statement Assume two stars are in circular orbit around a mutual center of mass and are separated by d = a. Assume angle of inclination is i and stellar radii are r1 and r2. Find an expression for the smallest angle of inclination that will just barely produce an eclipse. Homework...
