We hope you don't sit at your computer when there's a perfectly beautiful night-sky outside to observe!

Don't forget: the tools throughout this site are intended to help you observe the real sky!

One of the best (and most fun) ways of learning the constellations is by using CELESTIA!  (1.6.x)  Then go view them in your sky!

Are you unfamiliar with our 1.6.x and 1.4.1 links?  For an explanation  click here.

1.     New MoonsNew Moons essentially rise and set with the Sun and reflect no sunlight toward Earth.  So they do not impede Deep Sky Observing all night.

2.     Waxing Crescent MoonsWaxing Crescent Moons generally
rise between sunrise and "local
noon".  Setting between sunset
and "local midnight", they are up
and impede Deep Sky Observing
early in the evening.

3.     1st Qtr Moons1st Qtr Moons generally rise near "local noon".  Setting near "local midnight", they are up and impede Deep Sky Observing for the first
half of the night.

4.     Waxing Gibbous MoonsWaxing Gibbous Moons generally
rise between "local noon" and sun-
set.  Setting between "local midnight"
and sunrise, they are up and
impede Deep Sky Observing from
sunset through the early morning.

5.     Full MoonsFull Moons generally rise near
sunset, then set near sunrise.  So
they are up and impede Deep Sky Observing all night long.

6.     Waning Gibbous MoonsWaning Gibbous Moons generally
rise between sunset and "local
midnight".  Setting between sunrise and "local noon", they are up and impede Deep Sky Observing in the
late evening through sunrise.

7.     Last Qtr MoonsLast Qtr Moons generally rise near "local midnight" and set near "local noon", allowing Deep Sky Observing only during the first half of the night.

8.     Waning Crescent MoonsWaning Crescent Moons generally
rise between "local midnight" and
sunrise.  Setting between "local
noon" and sunset, they are up and

CELESTIAL EQUATOR AND ECLIPTIC

Below, scroll the sky map to the right and left to view the current circumstances along the Celestial Equator (aqua line) and the Ecliptic (red line).  You will notice that the Ecliptic is plotted in line segments, as the sky map is a composite, built up right to left of several segments, each accurate.  Remember: east and west appear reversed because you are looking up, not down.

Note that you may click on the name or symbol of any object in the above legend, which opens a separate page for that object.  This will show the object centered and zoomed-in on a map of a smaller, more detailed portion of the sky.

You will quickly find the locations of the Sun, the Moon, the major planets and dwarf-planet Pluto in the constel- lations of the zodiac, i.e. the constellations in which the Ecliptic lies.  The plane of Earth's orbit, the Ecliptic is generally regarded as the plane of the Solar System, and it is usually the most active part of the sky.  With this map and a  Larger More Detailed Version, which both open centered on the Vernal (March) Equinox (), you will be able to keep track of the long-term motions of the Sun, the Moon, the major planets and Pluto, in- cluding when they move past each other or past major stars.  For a slightly different perspective on this part of the sky, also see our  Sun's Apparent Motion along the Ecliptic  and  Sun's Location on the Ecliptic  pages.

THE MESSIER OBJECTS

The Messier objects rank among the all-time favorites of avid sky viewers!  This is because they can easily be viewed in small telescopes (as small as 4" aperature).  They thus include some of the most famous sky objects, many of which are known even to non-sky-enthusiasts.  M31, for example, is the famous Andromeda Galaxy and M42 is the Orion Nebula.

Here is a link to the SEDS site's excellent  Interactive Messier Objects page.  Clicking on each object's image leads you to loads of images and info, including its coordinates and diagrams to help you find it in the sky.

DEEP-SKY OBJECTS (DSO's)

The term "deep-sky objects" (DSO's) typically refers to celestial "groupings" or "formations" that are neither ordinary stellar systems nor members of any solar system.  These include star clusters, nebulae and galaxies, and they offer sky viewers some of the most captivating observations possible.  For example, the 110 Messier objects are all deep-sky objects.  But there are also myriads of others!

The New General Catalogue of Nebulae and Clusters of Stars (abbreviated "NGC") and the Index Catalogue (abbreviated "IC") are two standard references that offer lists of thousands of deep-sky objects.  (The Messier Objects are also included in the NGC.)

The SEDS site's  Interactive NGC Catalog Online  offers one of the best portals to information about deep-sky objects.

Wikipedia's  New General Catalogue  and  IC Objects  pages are also good sources of information about deep-sky objects.

Also check out  our own Deep-Sky Objects page.

OBSERVING PROGRAMS

Okay, we know it; the Universe is a "biggggggg" place!  So, at times, deciding which of the sky's innumerable marvels you want to observe can seem a bit daunting.  Would you like some help?  The  Astronomical League  has established some terrific  Observing Programs  to help you get the most out of your sky viewing.

VIEWING CONSIDERATIONS

THE EFFECTS OF TWILIGHT


HORIZON EFFECT


ESTIMATING ANGULAR DISTANCES

Since your hand is always "handy", you can use these rules of thumb (so to speak) to estimate how far apart objects appear in the sky.  Views are of your hand held out with your arm fully extended.

Another very useful benchmark to remember is this: a U.S. penny held 43 inches from your eye subtends an angle of 1° (one degree).


PARALLAX

Parallax is the apparent displacement of a closer object relative to a farther object as we change the position from which we view them.  Here's a nice little interactive that demonstrates  Parallax.

SKY-VIEWING
FUN FACTS

Though farther objects may be reported when viewing is exceptional, the Andromeda galaxy, M 31, is considered
to be the farthest object that can normally be seen by the naked eye!  It is roughly 2½ million light-years away!

Estimates place the number of stars visible to the naked eye at about 6,000!  That is over the entire 360° sky.

Apparent magnitude tells us how bright an object looks from Earth.  A bit like golf, where a lower score is best, brighter sky objects have lower apparent magnitudes!  For example, the Sun has an apparent magnitude of about -27 ("minus" 27).  Contrast this with Pluto, which has an average apparent magnitude of about +15 ("plus" 15)!

The un-assisted human eye, also called the "naked eye", can typically distinguish sky objects whose apparent magnitudes are +6.5 or less.  All observation of the sky was limited to this until the early 1600's, when the first telescopes were invented!

An 8" telescope can enable the viewing of objects with apparent magnitudes which exceed +14!
