You are standing on the Earth. The Sun is between you and the constellation Aries. Which constellation?

will the Sun be blocking in 6 hours. Explain please!You are standing on the Earth. The Sun is between you and the constellation Aries. Which constellation?In 6 hours the sun would still be in Aries. The sun moves across a plane in the sky called the ecliptic. The backdrop to the ecliptic are the 12 zodiac constellations. It takes 12 months for the earth to revolve around the sun, so the sun spends 1 month in each zodiac constellation.

What is the brightest star in the constellation aries?

Hamal (Alpha Arietis). Climbing the eastern sky in northern Autumn, Aries presents a small flat triangle below Andromeda dominated by mid-second-magnitude (2.00) Hamal. The name, directly from Arabic, means "the lamb," rather obviously standing in for the whole constellation of the Ram. The vernal equinox, the point, where the solar path crosses the celestial equator, is in Pisces south of the west edge of the Great Square of Pegasus. Over 2000 years ago, however, it was in Aries, having shifted westward into Pisces because of precession, the 26,000 year wobble of the Earth's axis. Around the time of Homer, the equinox was situated only nine degrees south of Hamal, allowing us to personalize the time that has passed since the Iliad and Odyssey were written. True to formal form, Bayer called Hamal the Alpha star and the second brightest ( Sheratan) Beta, but then quite broke down as the third brightest ( Flamsteed 41) has no Greek letter at all. Hamal is a warmish class K orange giant star. At a distance of 66 light years, it shines (allowing for infrared radiation) 90 times more brightly than our Sun. From this figure and an accurate temperature of 4590 Kelvin, the star is calculated to be 15.0 times the solar diameter. Hamal is characterized mostly by being so very normal, at least as far as a dying giant about twice the solar mass can be. Very little about it is unusual except for a mild deficiency in metals compared with the Sun. That in itself makes it rather valuable as a comparison for other stars. It has the honor of having (along with Shedar, Alpha Cassiopeiae) the most accurately-measured angular diameter, 0.00680 seconds of arc (a penny 60 kilometers away), from which we find another value for true diameter of 14.7 solar, beautifully in accord with that found from temperature and luminosity. This precise measurement allowed the detection of Hamal's "limb darkening." As a gaseous sphere, the Sun is slightly darker at the edge (its "limb") than at the center, the result of our not looking as deeply into the solar gases. Similar limb darkening can be detected in the members of eclipsing stars as they get in front of each other. Hamal is one of the select few single stars for which limb darkening has been seen, showing that we are not far from observing features on the surfaces of at least some of our stellar neighbors.What is the brightest star in the constellation aries?Its quite amazing how much information can be found online with just a bit of searching.



The brightest star in the constellation is Alpha Arietis (also called Hamal, Hemal, Hamul, Ras Hammel, El Nath) at magnitude 2.01.

It is a K-type giant star, slightly cooler than the sun at 4,590 K. It is 15 times the diameter of our sun, has twice the mass of our sun, and is about 90 times intrinsically brighter than our sun.

At a distance of 66 light years, it is the 47th brightest star in our skies.

Tell me about the constellation Gemini Twins!?

I am doing a project on that constellation and I need a good site to get information from!

Please answer to this if you know a site!

Thank you very much!Tell me about the constellation Gemini Twins!?http://www.stellarium.org/

Who discovered the constellation virgo and when?

When and who discovered the constellation virgo.

Full name pleaseWho discovered the constellation virgo and when?Constellations aren't discovered, they're invented. Someone picks out a pattern in the stars and makes up a story about it. This has probably been going on since the invention of language. Many ancient cultures recognized the pattern we know as Virgo, including the Indians, Egyptians, and Babylonians. Interestingly, many of them associated the pattern with a fertility goddess or other female deity.



The patterns we use now evolved over many centuries, so it is impossible, for all the prominent northern constellations, to attribute them to any one person. The exceptions are the southern constellations, many of which were named by Nicolas Lacaille, and some of the minor constellations of faint stars.



Or, you could say all the constellations were invented by Eug猫ne Delporte. He produced the 1930 proposal for defining constellation boundaries that was accepted as official by the International Astronomical Union (IAU).Who discovered the constellation virgo and when?As knowledge of astronomy pre-dates written history, the full name of the first person to point out that particular pattern of stars in the night sky, isn't something you'll ever be able to know.

So why did Obama cancel the constellation project to send us back to the moon and possibly mars?

http://www.nytimes.com/2010/02/02/scienc鈥?/a>So why did Obama cancel the constellation project to send us back to the moon and possibly mars?Because obama is a moron and he doesnt know what he is doing.So why did Obama cancel the constellation project to send us back to the moon and possibly mars?
I thought conservatives were about less spending???So why did Obama cancel the constellation project to send us back to the moon and possibly mars?He wants to use that money to promote his socialist agendas..
I don't know, because tax payer money is being spent on stupid things like healthcare , 2 wars, and a shitttty economySo why did Obama cancel the constellation project to send us back to the moon and possibly mars?Healthcare and a socialist agenda are more important that anything like that.So why did Obama cancel the constellation project to send us back to the moon and possibly mars?
I thought you guys didn't like science.
Fiscal conservation.





Look it up if you have forgotten what it looks like!!So why did Obama cancel the constellation project to send us back to the moon and possibly mars?
And if he hadn't you would be wailin', "Why is Obama wasting all of that money going to Mars".



Y'know... the way y'all think is not the mystery that you think it is.
On this I agree with BO. It may be the only thing. The space program is a waste of money; always has been and always will be.
Did he do that? Good for him! What a huge waste of money! Sure it would be cool, but it is not worth an unlimited amount of money.
The astronauts have already been there and gathered the required data, now it is onward for additional space exploration. We the people of course have not received the 'real information", so it is hard to justify any additonal space travel for "no reasonable return". Cover-up? probably. Isn't that the usual modus operandi?
It's not an entitlement program, and there's no way to tax it. It also would demonstrate America's technological superiority. Mustn't have that.



It also proves this guy is no JFK!
President Obama is calling on NASA to cancel the program that was to return humans to the Moon by 2020, and focus instead on radically new space technologies.





pay special attention here: and focus instead on radically new space technologies.





get it new technology,no different than retiring old jets.



Did you read this article or just the head line? The above was the first paragraph!!

How'd you miss it?
Something like 25% of our GDP went into the moon program - you got that kind of money?

The moon program was the REASON for the very high taxes in the late 60's and early 70's - you guys would flip out if Obama asked you for even one cent in taxes to pay for them. You know that right?

And nobody's landing on mars - not and coming back anyway, the logistics are a nightmare, it will never happen until we invent a completely NEW kind of power source, guaranteed!

Can sm1 plzz tel the location frm which constellation ursa major is visible,wen is it visible?

i only respond to people who post questions that i can actually readCan sm1 plzz tel the location frm which constellation ursa major is visible,wen is it visible?ouch :S that hurt my eyes. Please do your own home work!Can sm1 plzz tel the location frm which constellation ursa major is visible,wen is it visible?
I understand what you are writing, but it is extremely distressful to see it written like that. If I can suggest it, why don't you use an ENGLISH dictionary if you cannot spell the words correctly, it will make it much easier to read your question.

Which constellation will Mars go in retrograde this late autumn?? and for how long?

and when will it go back again?



also, can anyone explain, when it goes retrograde, like it is passing a car it seems like it is falling back?



but what about when it goes forward again?



i dont understand that part.



anyone can explain what is happening when it seems to go back and then forward again?



and again when will it do this?



please explain.Which constellation will Mars go in retrograde this late autumn?? and for how long?Mars goes stationary in Leo by mid/late December 2009, then slowly move retrograde around xmas eve. Retrograde motion will continue and somewhat faster as Mars moves to opposition on January 29, 2010. Mars will be just north east of the M44 the "Beehive" star cluster in Cancer. On Feb 4 Mars will be about 2 degrees north of M44.



Retrograde motion will continue as Mars moves through Cancer but will slow down and go stationary once more in early March. By the middle of March Mars will be moving forward ("prograde").



What causes this? Retrograde and stationary motion in a planet is APPARENT ONLY. What we see is a parallax effect from the motions of both our Earth and Mars (the other planets show similar motions, though when you get far out from the Sun these motions are small).



When you are seated in a car or bus (mainly that someone else is driving) especially on a multi-lane highway or freeway, look out the window and observe how other cars that you approach and then pass appear to move against distant landmarks or mountains behind. Clearly they are moving forward just as you are. Yet as you approach them they start to slow down relative to the background and then begin to move backwards from your perspective.



As you pass the other car(s) they continue to move backwards. The road starts to curve (the orbits of the planets are curved remember) away as the other cars now some distance behind us slow their apparent backwards movement and then begin to move forwards again relative to the background.



Think also of racetrack footage from the driver's point of view. As the car approaches slower moving cars they appear to move backwards as the car passes them.Which constellation will Mars go in retrograde this late autumn?? and for how long?I have no idea what all that means but i can tell you I'm about to eat a Mars Bar and that will take a few hours to pass.Which constellation will Mars go in retrograde this late autumn?? and for how long?Things we know.

Retrograde refers to a backward revolution or orbit. The planets revolve around the sun. The sun passes through the sky.

The constellations refer to the 13 (now 14, actually) signs of the zodiac.

Something we can infer.

Since Mars doesn't have a retrograde rotation, it must refer to the apparent direction mars travels in the sky (while orbiting the sun).



Sun travels through sky, mars travels around the sun (while it's traveling through the sky). So mars goes forward, then backwards, while traveling across the sky. Check when it is using whatever program you're using.
