Constellations

Constellations have fascinated astronomers for centuries. They are arbitrary formations of stars perceived as a figure or design, especially one of 88 recognized groups named after characters from classical mythology and various common animals and objects. Questions about the various constellations of stars are what this category is all about.

3,677 Questions

The number of constellations in the whole sky is?

The sky is divided into 88 separate constellations. However, new constellations have not been made up for hundreds of years, and when new stars are discovered they are simply thought of as being included with whichever constellation they are closest to.

How old is Orion nebula?

A Stellar Nebula is the dying core of a star surrounded by new stars. The dying core could be several different ages depending on what type of star it is and where it is on the H-R diagram. Red stars are the coolest, then Orange/Yellow (our sun), Then the hottest is blue. Another thing that comes to factor is how large the star was. Larger stars burn fuel faster then smaller ones and therefore have a shorter life. A Stellar Nebula is the first stage in the life cycle of a star.

What are the stars the three stars on this hunters belt?

The three stars that compose the hunters belt in the constellation of Orion are: Alnitak, Alnilam and Mintaka. They are 800 light-years, 1340 light-years and 915 light-years away from us respectively (but, of course, from earths perspective they are in a neat line).

Which constellation is directly overhead in spring?

That's going to depend on where you are on Earth (your latitude), and on what

date you decide to look, and on what time of day or night. You may not have

noticed that everything in the sky rotates, and every star rises, crosses the sky,

and sets, just like the sun and the moon do, and each star rises about 4 minutes

earlier every night than it did the night before. Whatever is directly overhead now,

won't be in a half hour from now.

Why can you not see the big dipper in Texas?

If you're anywhere south of about 35 degrees north latitude, then at least part of

the Big Dipper rises and sets; that is, there are some parts of some nights when

not all of its stars are visible.

If you're farther south than about 40 degrees south latitude, then none of the stars

in the Big Dipper is ever visible to you.

Why does some stars seem to wobble around in the sky.especially the one south east of the big dipper?

The description of "wobble" really doesn't paint a picture that's clear enough to

suggest what you're actually seeing.

If you see anything in the sky that appears to move with respect to stars, then

that object is either the sun, or else it's not a star. It could be a planet, an asteroid,

a comet, a meteor, the Earth's moon, or an artificial satellite.

"Southeast of the Big Dipper" also doesn't help. The Big Dipper ... and every other

pattern of stars ... either rotates half-way around the pole or else crosses the entire

sky, every night.

Constellations are named after?

These are different questions. The constellations were created from the imaginations of the people who observed the stars. Most of our "standard" northern hemisphere constellations were from Greek or Roman mythology.

Many of the southern hemisphere constellations were named by European sailors and navigators as they first sailed into southern waters. Note the nautical themed constellation names like "Sextans" and "Telescopium" and "Cetus", the whale.

The International Astronomical Union standardized all of the constellations, and assigned every visible star to one, and ONLY one, constellation.

When is the best time to see the constellation Bootes?

The hours of darkness, that is, the night-time, is the best time.

Bootes is somewhere in the sky at some time of every night

from roughly mid-December until mid-September.

Within that part of the year, the time that best suits your individual

preferences depends on what time and in what directrion, you like

to look for it.

For example, if you like to see it due south, high in the sky on your

local meridian, at 9 PM just as the sun sets, then mid-June is best.

How was big dipper made?

The big dipper is shaped like a pan, which in the past was called a dipper. Dippers were used to scoop up water. It gets the big part from being bigger than the little dipper, another constellation.

In what constletion do you find the little dipper?

The Little Dipper is an "asterism" ... a recognizable pattern of stars that doesn't include the entire constellation ... in the constellation of "Ursa Minor" (the "Little Bear"). In most of the USA, the Little Dipper is visible at any time of any night of the year, in the northern sky. The end of its 'handle' is Polaris, the North Star, which appears to never move. The handle remains nailed to the North Star, and the dipper spins around it like the hand of a clock, once in 24 hours.

Who saw the constellation Big Dipper first?

There is almost certainly no record of this. The Big Dipper is part of Ursa Major and the Little Dipper is Ursa Minor. Given the latin names and the fact that both are easily visible with the naked eye means that they would have been discovered millenia ago.

How did the ancient Greeks explain constellations?

Many of the constellations were related to myths. Generally the figure was important enough either to the gods or to humanity that the gods granted them immortality by being placed in the heavens. An example is Ursa Major and minor (the Big and Little Dippers). According to Greek myth, Zeus had an affair with a nymph named Kallisto. He disguised himself as Artemis and forced himself on her. When it was discovered that she was pregnant, Artemis expelled her. She gave birth to Arcas (progenitor of the Arcadians). Zeus discovered what happened and transformed her into a bear. Many years later, she came upon her son while hunting, and he raised his spear to fell her as she approached to embrace him. Zeus immediately intervened and placed mother and son among the stars.
