Partial Solar Eclipse for North American Skies

Check out this map for your location and see how much of the sun the moon's shadow will be biting away.

On late Thursday afternoon, North American skies will be graced with a most beautiful sight as the moon’s shadow appears to bite into the sun.

An eclipse of the sun occurs when the Earth, moon and sun line up. However, unlike a total eclipse where the entire face of the sun is covered up by the moon passing in between, on Thursday only part of the sun will be covered by the moon. Depending on where you are, anywhere from 18% to 81% of the sun will appear hidden from view.

For more details about this event click here for my Geekquinox article.

Be very careful and please do not look at the sun directly with the naked eye.  For safely viewing the eclipse, please consult my National Geographic article.

Eye of Bull Watches Moon

On Saturday, October 11, the moon slides next to the bright orange star Aldebaran.

Also known as the Eye of the Bull, this orange giant star is located 68 light-years away but will appear only three degrees away from our natural satellite, which is equal to the width of your three middle fingers held together at arm’s length.

Views through binoculars will be particularly pretty as the moon will appear to lie right in the middle of the distinct V-shaped star cluster, the Hyades.

Luna Looks Upon Sisters

As the gibbous moon wanes in the eastern sky on Friday, October 10, it can act as a guide to finding the Seven Sisters.

Nestled in the constellation, Taurus, the Bull, the Pleiades or Seven Sisters is an open star cluster that can be seen by the naked eye in suburban skies. Sitting about 400 light-years away, this deep-sky treasure appears to be a fuzzy patch to the naked eye, but with a pair of binoculars or a small telescope this tiny cloud turns into stunning jewels.

When you find the moon, look to the left to find this cluster just ten degrees away, equal to the width of your fist held at arm’s length.

Blood Red Moon Shines

Written by The Night Sky Guy on October 7, 2014 – 2:11 pm -

Head out just before dawn to see your own blood red moon Wednesday, Oct. 8. Total lunar eclipse seen April 2014 by Tomruen from California.

Total lunar eclipse as seen April 2014 by Tomruen from California.

On the morning of Wednesday, October 8 the moon will turn blood red, just in time for an early Halloween treat.

Just before the sun rises, the moon will be eclipsed by our planet’s shadow. Starting at about 5:15 am EDT the moon will look as if little bites of lunar cheese are eaten away by a hungry celestial mouse and will appear to be slowly disappearing. As the eclipse reaches totality, a ruddy hue will appear across the surface of the moon. The moon is not really turning red, of course, this change in colour is due to dust particles in our atmosphere. This strange and magical transformation will occur at about 6:25 am EDT.

Eastern North America will not get a chance to see the moon regain it’s full girth as this eclipse coincides with the rising of the sun and the setting of the moon. However, skywatchers in the west will be able to see the moon reappear. For more information about lunar eclipse viewing in your area, check out my National Geographic article.

If you miss this one, don’t worry, you will be treated to another total lunar eclipse on April 4th, 2015.

Stay tuned for the sun’s turn on October 23 for a partial solar eclipse. You will need to protect your eyes for that event. You can buy them at Astronomers Without Borders, a non-profit organization, at a 15% discount, just in time for the big event.

Hungry Galaxies Gobble to Grow

In the universe, it’s survival of the largest! Instead of growing younger stars, galaxies tend to cannibalize smaller neighbouring galaxies.

All galaxies start small and gather gas which can in turn become new stars. As more and more mass accumulates, galaxies grow and gain more gravitational strength and therefore more easily pull in their neighbours.

To be gobbled or not to be gobbled? Our own Milky Way is measured to be a on the obese size growing as it snacks on stray star islands, in fact, research shows that we haven’t had a galactic meal for a long time. Although in about 4 billion years, we could be chomping on such neighbours as the Large and Small Magellenic clouds, two nearby dwarf galaxies.

However, we better be on the look out as tables may turn, we may fall victim to big brother Andromeda galaxy found some 2.6 million light-years away from Earth. This won’t be happening any time soon, though, maybe in about 5 billion years.

For more about this and how your can see your own gobbling galaxy, check out National Geographic’s Star Struck Blog.

Celebrate the First Day of Autumn!

Written by The Night Sky Guy on September 24, 2014 – 12:26 pm -

moon equinoxAutumn officially started on Monday, September 22 at 10:29 pm EDT in the Northern Hemisphere and spring in our Southern counterpart.

As the Earth’s axis tilts back and forth away or toward the sun, it results in our changing seasons, however, during the Equinox the Earth’s axis is not tilted. As the name implies – Equi meaning Equal and nox meaning night causes an equal amount of hours of daylight as those as night.

Our galactic neighbourhood contains some hundred million billion suns (100 quadrillion) and stretches some 500 million light years across. Our solar system sits about the third of the way from our galaxy’s centre – about 28,000 light years distant.

Swan Reaches for Dumbbell

Written by The Night Sky Guy on September 17, 2014 – 9:00 am -

Swan reaches for Dumbbell
Sky-watchers who have small telescopes or binoculars will have a little help from the flying swan on Thursday, September 18 to glance at the Dumbbell nebula.
Those who are live in mid-northern latitudes can look straight overhead to find Cygnus, the swan, also known as the Northern Cross, this bright pattern is easy to see this time of the year, even in the light-polluted suburbs.
Using binocular, scan just one field of view below Albireo, which marks the head of the swan. About 8 degrees under you might notice a faint, tiny cloudlike spot known as the Dumbbell Nebula or Messier 27.
Shining at magnitude 7.3, it is an easy target for even small backyard telescopes. With its double-lobed shape, it looks a lot like its name implies.

Uranus Paired with Moon

Written by The Night Sky Guy on September 10, 2014 – 2:18 pm -

uranus-clouds-nasa-esaOn Wednesday night sky-watchers in eastern Canada, Greenland, and parts of Siberia will see Uranus hide behind the moon.

This occultation will begin at 8 p.m. when the moon is still at the horizon and then reappear at 8:40 p.m. Looking so low to the horizon will be challenging as skywatchers will need a clear line of sight toward the eastern horizon. So take out your binoculars or telescopes and try this low lying peek-a-boo.
