Moons Drop Shadows on Jupiter

Written by The Night Sky Guy on January 9, 2016 – 3:41 pm -

Sunday night watch the shadows of 3 major moons of Jupiter drop their shadows onto the surface of the gas giant.

Late on Sunday, January 10, and into the overnight hours, telescope users can watch as Jupiter’s three largest moons travel in front of the largest planet in the solar system.

The sky show begins at 11:37 p.m. ET, when Europa’s tiny disk begins its trek across the planet, a journey that ends at 2:21 a.m. ET on Monday. Calisto then starts its transit at 3:04 a.m. ET, followed by Io’s shadow, which will touch the gas giant’s disk at 4:22 a.m. ET. Finally Io itself will begin to move in front of the planet at 5:27 a.m. ET.

All this action takes place so far away that the sunlight reflected off Jupiter and its moons takes 41 minutes to reach our eyes here on Earth.

Sliver Moon Snuggles King

The King of the Planets joins the whisker-thin moon as the top a Venus/Mars pairing on November 6.

The morning of Friday, November 6, the moon will shrink to a crescent, snuggling up to the right of Jupiter, the king of the planets. 

The pair will be very eye-catching at only two degrees apart, equal to the width of four lunar disks. Adding to the beauty will be the Venus-Mars pair, hanging just ten degrees below.

Amazing Stargazing Sights This Week

On this very special week we celebrate Valentine’s Day the sky is full of romance too with the moon pointing to a giant  lion’s heart and the mythical goddess of love shining at its most brilliant.

Over the course of the next few days there is a whole line-up of stargazing targets for both the unaided eyes to backyard telescopes.

The brightest planets in the sky remain both Jupiter and Venus. Meanwhile you can still catch Mercury as it is fading fast low in the evening twilight in the southwest horizon.  Your best chance to see the innermost planet now is with binoculars.

Mars aficionados will have to wait until near midnight for it to rise in the east and will be at its highest in the south in the pre-dawn hours. If you have good atmospheric conditions a telescope will show off some of its largest surface features. Best views of the Red Planet though will be in April when its apparent diameter will be 50% wider.

Finally Saturn rises around local 1 am  and climbs to its highest point in the southern sky by dawn.  You can get a two-for-one deal since Mars will be its far right.

Get all your observing details for these and other sky events this week at my weekly skywatching column at National Geographic News.

Look Up At Planet Sky Show

Written by The Night Sky Guy on May 24, 2013 – 2:02 pm -

Skywatchers around the world get set to see a striking triple planetary meetup in the evening skies the likes of which won’t be repeated until 2026.

From May 24 to 27, Mercury, Venus, and Jupiter will appear to converge in the low northwest sky after sunset and all you need to see this event are just your eyes!

The best part of the show will be on May 26th when all three planets are huddled together in a tight triangular formation. Check the image below for what it will look like in your low northwestern sky.

Jupiter joins Moon in the Evening Sky

Written by The Night Sky Guy on April 12, 2013 – 9:20 pm -

If you have clear skies in your neck of the woods over the weekend of April 13th then step outside and look west for a beautiful pairing between the Moon and some of the brightest stars and planet in the night sky.

While conjunctions like thee are not rare by any means, they do make for a great opportunity to track down some celestial objects that otherwise may be a challenge to find for beginner stargazers.  And for those more experienced navigating the heavens, this cosmic close encounter makes for a pretty photo op.

Jupiter Hit by Meteor Again!

Written by The Night Sky Guy on September 13, 2012 – 2:22 pm -

Early Monday morning two American amateur astronomers  independently spotted a bright flash of light in the upper cloud-deck of Jupiter – the fourth impact on the gas giant discovered in just the last three years.

Early suspicion by astronomers is that a meteor or comet had hit the atmosphere of the planet – and the fact that it was visible from Earth through backyard telescopes more than 730 million km away – indicates it was probably a significant event.

Read the rest of my Jupiter explosion story at National Geographic News

Check out the actual 2-second video frames of the impact on Jupiter this week as captured by a webcam attached to a 12″ LX200 Meade telescope by a backyard astronomer in Dallas, Texas.

Perseids Meteor Peak Tonite and Hit Moon!

Written by The Night Sky Guy on August 11, 2012 – 12:30 pm -

Warm summer nights and awe-inspiring shooting stars are an unbeatable combination! That’s why skywatchers look forward to the annual Perseid meteor shower. Visible with the naked eye from the city to cottage country, dozens of “shooting stars” will light up the late-night skies. With the waning crescent moon rising above the horizon only around 1 am tonight, the peak date of August 11th, this cosmic light show will surely put on an impressive display. Skywatchers get to see a flurry of shooting stars start 10 pm with rates increasing until pre-dawn hours Sunday. Anywhere from 20 to 80 shooting stars per hour depending on local sky conditions.

Here is my Night Sky episode that talks all about the shower and some bonus planets that are joining the show too!

EXTRA:  Sky-watchers with backyard telescopes, though, might join NASA in training their lenses on the moon for an elusive, potentially flashy Perseid sideshow.

Read my National Geographic observers guide for more information on how some backyard telescope owners watch Persieds actually impact the moon!… http://news.nationalgeographic.com/news/2012/08/120810-perseid-meteor-shower-perseids-science-space-astronomy/

It’s worth waking up early these days to check out the amazing view in the eastern sky at dawn. Venus dominates the sky, while Jupiter to its upper right and the Pleiades star cluster complete the picture postcard view!.

Astrophotographer Marc Ricard captured the cosmic scene this week from Warkworth, Ontario using a Canon 60D DSLR with a single 19 second exposure and 35mm, f/1.4 lens. Look carefully and you can even see the strong light from Venus illuminating the clouds in front of it! Wow! The goddess of love is burning bright now.

Shots of the Sunset Show this Week

Written by The Night Sky Guy on March 27, 2012 – 11:28 am -

In Montreal,  Canada, where I am based skies are about 60% cloudy so chances are usually that I miss an astronomical event but this week I have been blessed with some clear skies and managed to catch at least some of the planet-moon show going on in the western sky at sunset.  Here are a couple of my attempts at capturing the cosmic beauty of the Venus-moon conjunction of March 26, 2012.
