Two Sun/Earth alignments, and plumbing the depths for Pluto

This week’s “Eyes on the Sky” details who is best situated to see the lunar eclipse of June 4, how nearly everyone worldwide can watch the Venus Transit of June 5 (or 6th, depending on your location in the world – also see links below last week’s video), as well as a really difficult challenge: PLUTO!  This 14th magnitude icy body revolves around our Sun at nearly 3 billion miles distance; can you spot this tiny, dim speck in Sagittarius?  This week’s video shows you how to learn the area it’s in, some fantastic clusters you can see easily even with binoculars from light polluted areas, and when to look to try and find the 9th plan…. errr – previously-the-9th-planet.  (See link to PDF finder chart, below).  Check it out, and “see what’s up” in the sky this week.

Venus Transit: Transit lunar craters, transit history, and more

The Transit of Venus across the face of the Sun only occurs twice every 100+ years.  On June 5/6 (depending on where you are in the world; it will be on the 5th in the United States), the last chance humans will have to see the disk of Venus transit across the face of the Sun will occur.  Accurately calculating the times the transit occurred in the past helped astronomers hundreds of years ago to calculate the distance from the Earth to the Sun, also known as the Astronomical Unit (AU).  Because these transit viewings and calculations were so important to understanding the size of our own solar system, quite a few craters on the Moon have been named after astronomers of the past involved in these efforts.  This week’s video takes a look at some of these craters, astronomers, and prepares you for this last-in-our-lifetime transit.  Check it out, and “see what’s up” in the sky this week.

Lots of links about the Venus Transit

Eyes on the Sky’s solar safety video can be seen here, along with ways to make safe solar viewing equipment.

Here’s how to safely photograph the transit.

Two crescents on the 22nd; Hunting in the Dragon

With the Venus Transit just a couple weeks away, the brilliant point of light in the western sky is sinking towards the horizon.  And given the recent solar eclipse seen by much of the Pacific area of the world on the 20th, the Moon is just past new, and pays a visit to the planet.  Check out how these two crescents can be seen easily from most any location.

Looking to the north, we find the constellation of Draco the dragon.  Though dimmer overall than many of the more prominent constellations, it’s location near the Big Dipper and the bright star Vega means that we can go hunting for some interesting objects with binoculars and telescopes.  For a star charts of the Draco region, click here and download Star Charts #1 and #6.  And don’t miss Saturn near a couple of brighter stars in Virgo, neatly framed in a wide-field telescopic view.  Check it out, and “see what’s up” in the sky this week.

Binocular binaries in Bootes; May 20 solar eclipse

Last week’s video showed a number of double stars that can be spotted in the “ice cream cone” shaped constellation of Bootes, the Herdsman.  This week there are more double stars to see there – all of them easy, and all can be seen naked eye or with binoculars.  Check out these great color-contrast objects this week.  And on May 20th, an annular solar eclipse will occur, and many in the western United States will have a chance to view parts or all of it.  Be sure to see the week’s “Eyes on the Sky” for when to view it, and how to view it safely (DO NOT look at the Sun directly during the eclipse!).  Wishing you clear and dark skies (well, except for the eclipse)!

You can find more information about the May 20 solar eclipse on NASA’s website.

View the solar eclipse safely by making a simple pinhole solar viewer.

Mars and more Messiers; Bootes doubles up

Mars makes moves heading out of Leo starting this week, but not before it gives us one last pointer to the Leo Triplet of M95, M96 and M105.  Faint galaxies all, but worth attempting if they have been difficult to find previously for you.  If that challenge is a bit too much for your skies, take a whirl back over to Bootes, and see “double” with some double stars lurking in the Herdsman.  Wishing you clear and dark skies!

Venus at brightest; a celestial time trip(let)

Venus will be taking center stage in about a month when it transits across the face of the Sun for the last time in 105 years.  But it manages to steal the spotlight by outshining everything else in the sky except the Sun and the Moon.  Learn how to spot its phases with a a telescope, or catch the brilliant planet’s dazzling glow near a fairly bright star in Taurus, which will look quite dim in comparison.

Later in the week, the nearly Full Moon glides by Saturn and Spica.  These three objects are vastly different distances from each other, and contemplating the time differences of light from each is a pretty cool exercise to consider.  Use a telescope to spot Saturn’s rings.  Wishing you clear and dark skies!

Luna splits Beauty and the Bull; an eye on Cor Caroli

Early this week, the Moon splits some well-known star clusters, and visits the brightest planet.  Don’t miss the interesting take on earthshine, as the time it takes for light to reach your eye from the Moon really can vary by several seconds, even while looking at the same Moon!

Close to overhead this time of year just south of the Big Dipper, and therefore visible from most any location for stargazing – even in cities – is the small constellation Canes Venatici, which harbors some great objects that can be spotted with simple binoculars or small telescopes.  Cor Caroli, the star named after England’s Charles 1, is a central highlight of this week’s video.  Wishing you clear and dark skies!

Catch a couple crescents and eyeing Orion

Late waning and early waxing (i.e., very thin) crescent Moons are beautiful sights, but can be tough to spot and see.  Eyes on the Sky will show you where to look in the early morning this week to see the slender waning crescent Moon in the eastern sky, then where to look again as the Moon reappears in the evening western sky.

Orion is fading into the southwestern evening sky, but still remains high enough while it is dark to spot some interesting double stars spotted with binoculars or with a small telescope.  Don’t miss the 3-D “zoom in” perspective of Orion’s belt stars, which all appear to be in a line and of equal distance – check out the surprising result of zooming in!  And lastly, with the “Mayan calendar” hype occurring, learn a bit about what the Maya saw in this part of the sky too.
