 “The Hubble Space Telescope shows a rare view of a pair of overlapping galaxies, called NGC 3314. The two galaxies look as if they are colliding, but they are actually separated by tens of millions of light-years, or about ten times the distance between our Milky Way and the neighboring Andromeda galaxy. The chance alignment of the two galaxies, as seen from Earth, gives a unique look at the silhouetted spiral arms in the closer face-on spiral, NGC 3314A.” ~ from the Nasa website.

If you look in the northern hemisphere’s summertime sky, you’ll see the lovely swan winging through the night.  This image of Cygnus-X ( a giant star-forming region in the Milky Way) was captured by the Herschel Telescope with combined infrared data.  Herschel is a European Space Agency mission.  Its science instruments are provided by a consortia of European institutes, and NASA is a participant in Herschel.

This image of the Large Magellanic Cloud (dwarf satellite galaxy of the Milky Way) was taken by the NASA/ESA Hubble Space Telescope’s Wide Field Planetary Camera 2.  This loose star cluster — known as a stellar grouping — is classified as an OB association.  OB’s usually contain 10-100 high mass stars with brilliant but short lives.  Speculations is that most of the Milky Way’s stars were created in OB associations.

This gorgeous image was taken by the Herschel Space Observatory, using a photoconductor array camera and spectrometer, spectral and photometric imaging receiver and XMM-Newton (space satellite).  What you are seeing here is the intensely cold nebula’s gas and dust emissions.

You can read a more in-depth, scientific explanation here on the NASA website.  Herschel and XMM-Newton are both European Space Agency missions.  The Jet Propulsion Laboratory in Pasadena, California contributed mission-enabling technology for two of Herschel’s science instruments.

Hot Stars So Close Yet So Far Away

January 17, 2012 at 12:32 pm | Posted in Astronomy, Regular Feature, Science News | Leave a comment

Close but far as in the next galaxy over.  The satellite galaxies, the Magellanic Clouds visible in the southern skies, have a couple of excitable beauties in their midst.  AB7, a binary star, has very strong stellar winds that continuously eject energy particles from 10 to 1,000 times more intensely than our own star, the sun.  You definitely don’t want to get too close to this pair because AB7 is hotter than you can handle; as in surface temperatures that exceed 120,000 degrees.

The green filament visible in the upper left just outside the clouds are the remains of a super nova explosion.

NASA Allows You To Explore The Solar System

For Science Tuesday this week I wanted to share with our readers this incredible new tool from NASA that allows you to explore the solar system using a phenomenal new interactive 3D program. The program is named “Eyes On The Solar System” and allows you to follow all deep space probes launched from Earth. You can pan around the solar system and follow each craft to every planet or moon it has visited. You can observe as the various craft enter or break orbit of each body they visit along the way.

You are required to download and install an additional plug-in for your web browser to use the program. It took me all of a minute to accomplish this simple task and when you begin using the program it becomes evident why the plug-in is necessary. I don’t think the team that built IE8 or Firefox 6 quite had this in mind.

Getting up close and personal with one of my favorite planetary systems.

Watch Today’s Lunar Eclipse From Anywhere – Thanks Google

Call this a “Science Tuesday Supplemental”. It’s supplemental because it’s Wednesday. After calling the cosmos and being turned down in my request to move today’s lunar eclipse to either a Tuesday or Thursday, as those are the normal days for our real science reports here on Roqoo Depot, I’ve decided that this was too big an event to let slide. Thus, we have our supplemental report.

In order to allow everyone on Earth with an internet connection to view today’s Lunar eclipse, scheduled to begin at 11:20 PDT (2:20 EDT) the good folks at Google will be providing a variety of viewing options for North American astronomy enthusiasts who will sadly miss the event due to daylight.

Your first option would be to watch the live streaming video on the Google Youtube channel which can be accessed by clicking here.

Another method of viewing would by via the Slooh Space Camera app for Android phone users. You can download the app by clicking here.

Last but not least, you can view from your computer desktop by simply downloading and installing Google Earth to your computer. You will find the download page by clicking here.

While watching the livestream on Youtube seems to be the easiest way to watch today’s awesome astronomical attraction, I suggest either the Slooh app or Google Earth for anyone with a real interest in viewing images of our planet and the space around it on a regular basis.

So for you lucky folks around the world who will see the eclipse in real time, live and in person, enjoy the show you lunatics. Those of us here in North America will have to enjoy the show on line.

Eyes On The Sky – This Month in Astronomy – June 2011

The Lonely Shepherd

Quick!  Name a constellation.  Which one comes to mind?  The Big Dipper?  Leo?  The Gemini twins?  Orion?  Perhaps Draco the Dragon or Perseus?  Hercules the Hero?  The teapot-shaped Sagittarius?  Cassiopeia? Or maybe the beautiful Andromeda?

Ask people to make a list of constellations they know or have at least heard of, and the name  Boötes probably wouldn’t appear in the top 10.  Or even the top 20.  In fact, it probably wouldn’t appear on most people’s lists at all.  It is without a doubt one of the most overlooked, most forgotten of the modern constellation.  A lonely shepherd wandering the skies.

Boötes (pronounced boh-OH-teez) is a prominent constellation in the late Spring and early Summer.   Although it seems to have fallen into obscurity with the passage of time, it is one of the oldest constellations ever documented and has a variety of myths and legend associated with it.  An Arab legend sees the circumpolar stars as a flock of sheep and Boötes as their shepherd. Other early civilizations in the Mediterranean and Middle East saw Boötes as a herdsman, cart driver, or plowman.  Greek mythology had several references to the constellation.  In some legends it represented the son of Zeus and a nymph, Callisto.  Homer referred to Boötes in his epic story The Odyssey.   And some of civilization’s earliest star-charts show Boötes as a running figure holding a spear.

To modern star-gazers like us, Boötes is easily recognized as the shape of a kite with its bright Alpha star Arcturus anchoring the constellation at the point of the kite where the tail is attached. Arcturus is a red giant star only 36 light-years away from our own humble home.  It is the fourth brightest star in our night sky.

The easiest way to locate the constellation is to locate Arcturus using a favourite star-hopping phrase:  Arc to Arcturus!  How do you Arc to Arcturus?  Locate the Big Dipper which is directly overhead in our June sky. Follow the handle’s arc shape past the last star, straight on through to the brightest star you can spot along the line of that imaginary arc, and you’ll have found Arcturus. From there, the rest of the constellation should be easy to assemble: the body of the kite shape comprised of the five stars above Arcturus, as well as the tail of the kite – one star on Arcturus’s either side.

Other Heavenly Happenings

The constellation Boötes is the radiant point of a meteor shower this month.  While not one of the showiest of meteor showers, the best viewing for this herd of shooting stars will be the early hours of the morning June 27th and 28th.

For those who own a telescope, Saturn is a sight to behold this season as our view of the gaps between the planet’s rings becomes more prominent.  For those without a telescope, Saturn – though a distant planet – is definitely visible to the naked eye. Through June it appears in the constellation Virgo, to the right of Virgo’s alpha star Spica (pronounced spEE-kah).  To find Spica, use the star-hopping technique you used to Arc to Arcturus.  Continue the arc down toward the south-west horizon and Speed on to Spica.

Finally, the planetary summit which gathered on the low Eastern Horizon in May is coming to an end.  Jupiter will break away from the group and start a dramatic ascent throughout June.  If you are late to bed or an early riser, look for this spectacular point of light in the Eastern sky a few hours before sunrise.  It will be unmistakable and breathtaking.  No matter the season, the King of Planets never fails to put on a show!
