Times For Emerging Crescent Moons
Below are times for viewing Crescent Moons in UT for Dublin, Ireland. Crescent data is specific for your location but adding your timezone offset from GMT to the Sunset and Moonset times will give you an idea of when the Moon is visible locally. The amount of time you have to see a crescent and what percentage of the Moon is illuminated will be somewhat different for where you live. LunarPhase Pro will calculate all this information specifically for your location. The data in the screenshot below was generated by the software.

Events for March 2017

In case you’re not aware, Jack Horkheimer, who used to produce these Star Gazer videos, died on August 20, 2010 and staff at the Miami Planetarium have been producing them in his place since then.

What Messier Objects Are Visible Tonight (March):

A list of messier objects visible this month. All are possible with binoculars, most are easy even with small binoculars.

This month we will look for 10 objects, 8 open clusters in the southern
milky way and a pair of galaxies, all are within reach of binoculars.
The open clusters are easy binocular targets and most are visible with
the naked eye. M81 and M82 are difficult binocular targets that offer
a stunning telescopic view.

M41

This cluster in Canis Major is visible as a hazy patch to the
naked eye just below Sirius. M41 is resolvable in binoculars and
appears fairly loose in telescopes at low power.

M93

This is a small fuzzy patch of light in Puppis, partially
resolvable in binoculars. The hardest part of finding this cluster in
binoculars is picking it out of a fairly rich region of the milky way.
Use low power to examine this cluster and the surrounding richness in
a telescope. Medium power provides a nice view of the cluster itself.

M47

A bright cluster in Puppis, easily visible as a hazy patch to the
naked eye. Binoculars will show a large hazy patch with many stars
resolvable. Telescopes show a fairly loose cluster with stars of wide
variety of magnitudes.

M46

This cluster is right next to M47 and is also visible to the
naked eye. In binoculars M46 appears as a large hazy patch with no
stars resolvable, giving a nice contrast to M47. In telescopes at
low powers this cluster evenly fills the eyepiece. While you are here
go to medium or high power and look for the planetary nebula NGC2438.
It will appear as a faint uneven ring, with a blue/green color.

M50

An open cluster in Monoceros. This is a small hazy patch in
binoculars, partially resolvable. Like M93, the richness of the
surrounding field is the only difficulty in finding this object.
This is a fairly tight cluster at low power in a telescope.

M48

Moving on to Hydra, we find another naked eye cluster. M48 is
a large fuzzy patch in binoculars, partially resolvable. Use low to
medium power in your telescope for a spectacular view.

M67

In the southeast portion of Cancer is another open cluster,
barely visible as a fuzzy patch to the naked eye. Binoculars show
M67 as a large hazy patch of light, similar to M46. Use low power
to resolve this large, rich cluster in a telescope.

M44

Known as the Praesepe or Beehive Cluster, this open cluster
is easily visible to the naked eye as a large, fuzzy patch bigger
than the moon. Binoculars or rich field telescopes provide the
best view of M44.

M81,
M82

This pair of galaxies in Ursa Major are very possible to
see in binoculars, they look like a pair of fuzzy stars. Both
galaxies will fit into the same low power telescope field. M81 will
appear as a large oval gray patch of light. M82 is a pencil like
streak of light next to and perpendicular to the long axis of M81.

Giant storms swirl through the clouds of Jupiter in this false-color image from Juno, a spacecraft that is orbiting the giant planet. The storms include a bright swirl at lower left, and what looks like a dark "hole" at lower right. Juno is expected to sweep just 2,700 miles (4,400 km) above Jupi...

Growth Spurt

27 Mar 2017 at 12:00am

One of the most impressive galaxies around climbs high across the south on spring nights. M87 is a giant elliptical galaxy, so it looks like a fuzzy rugby ball, with no spiral arms or other major features. It’s in the east at nightfall, and is visible through a small telescope.

M87 contains sever...

Busy Galaxy

26 Mar 2017 at 12:00am

M82 is one of the most vigorous galaxies around, as this Hubble Space Telescope composite image attests. Winds from hot young stars, as well as powerful stellar explosions, blast debris away from the galaxy's disk (red filaments). The galaxy is giving birth to stars at about five times the rate o...

Satellite Predictions and Visibility

NASA Skywatch
NASA SkyWatch is a web-based Java application that provides sky watchers worldwide with a picture of when and where the International Space Station, the space shuttle and other spacecraft can be seen with the unaided eye as they pass overhead.

Heavens Above
Provides all the information you need to observe satellites such as the International Space Station and the Space Shuttle, spectacular events such as the dazzlingly bright flares from Iridium satellites as well as a wealth of other spaceflight and astronomical information.

Online Skymaps and Charts

Your Sky
An interactive planetarium run by Fourmilab. You can produce maps for any time and date, viewpoint, and observing location. If you enter the orbital elements of an asteroid or comet, Your Sky will compute its current position and plot it on the map. Each map is accompanied by an ephemeris for the Sun, Moon, planets, and any tracked asteroid or comet. A control panel permits customization of which objects are plotted, limiting magnitudes, colour scheme, image size, and other parameters.

Heavens Above
Provides a range of charts and information, including sky charts for your location (which you’ll have to specify).
