Happy 20th, Hubble – and Thank you!

Saturday, April 24th, 2010

On this last day of the month that celebrates the Hubble Space Telescope‘s 20th Anniversary, as our own little “thank you” for a mission that has so eloquently revealed the magnificent cosmos to a curious space-faring species in one little corner of the Universe – we present our favorite Hubble image and why it is our favorite.  Of course, because there are two of us, we have two favorite images.

The first is Rob’s favorite – Hubble’s 1995 “Deepest View of the Universe“:

“My favorite Hubble picture is an image I think about ALL the time.   When Tavi asked me what my favorite was, it didn’t occur to me that a permanent fixture in my imagination, is that favorite image.  This picture has changed the way I look at the nighttime sky and the way I look at us here, on this wet, rocky world.  It makes my heart pound and my intuition ring inside me like a big church bell.  To me, it is one of the most important images ever taken.

I heard the size of the FOV described as this: take a tennis ball and view it 100 meters away, that is the area of sky contained in the Hubble Deep Field image.  Sometimes at night, when it is moonless and I am staring at the target area, near Megrez in Ursa Major, I think about how that image extends everywhere around us.”

The second is Tavi’s favorite – Hubble’s 2009 “Butterfly Emerges from Stellar Demise“:

“At first glance, Hubble’s “Butterfly Emerges from Stellar Demise” reveals the stunning complexity of a dying star; but it is the date of this image that reveals an even greater saga – the stories of yesterday’s aspirations and heartaches, today’s determination, and tomorrow’s promises.

“Butterfly Emerges from Stellar Demise” was acquired on July 27, 2009 – a full six-and-a-half years after the tragedy that originally grounded NASA’s Servicing Mission 4, just two months after that mission was finally accomplished, and a mere six days after Rob and I had the distinct privilege of meeting the very astronauts who installed the camera that took this image.

I was twenty-five years old the day that the Hubble Space Telescope was let loose from the hands of mission STS-31.  I knew virtually nothing about Space and the Universe, and I’d looked through a telescope only once in my life – a borrowed dimestore version to get a closer look at “that unusual star” on my west Florida horizon.  Back then, my interests were centered on exploring the wild environment of Florida and basking in the serenity of the Gulf of Mexico.  It never even occurred to me that there might be a more fascinating world beyond this planet – much less, that it would ever be within my reach.

Then, in 2002, I happened upon Hubble’s 1999 image of the Ring Nebula, “Looking Down a Barrel of Gas at a Doomed Star.” It was just the image, with no real description – a mere glimpse into an entirely foreign world – but I was immediately intrigued.  From that moment on, I sought a way to explore this new horizon, to somehow become part of it.  I started slowly, with a pawnshop telescope, but always, I had that image in my mind and my mind on the Universe.

Today, I am immersed in all things Space, with a primary focus on encouraging others to “look up.”  I know that, like me, there are many souls who’ve never imagined the intricate splendor that is our Universe, and that it takes but a sprinkling of stardust, a gentle nudge, to open their eyes the way that Hubble opened mine.

Just as one brilliantly fading star evolves into the promise of many new stars, “Butterfly Emerges from Stellar Demise” embodies the past reaching out to inspire the future.  And it is Hubble that puts that splendid vision of rebirth into our hands.”

Through Hubble’s eyes, we are encouraged to look beyond the boundaries of this small, beautiful planet to experience the wonders of an entire Universe.  To all the people behind the Hubble Space Telescope – from those who first dreamed of it, to the NASA and ESA Teams who made it happen, to the individuals who share the images with the world – I express my humblest and deepest gratitude.

Happy 20th Anniversary, Hubble – and thank you, Team Hubble.

12/23/2009 Update: Video archive of this webcast can be found here.

Throughout billions of years, the Moon has held an intrinsic practical and emotional bond with our planet.  Sadly, we are losing the human connection as we keep our eyes fixed on the material and social noise of today’s world.

Every once in a while, something special comes along to remind us to pause and look up at Luna, to consider that constant, though oft-forgot, guidepost for all living things on Earth.

We are proud to announce our next AFM*Radio special event, an audio/visual presentation, Moon-Walking with Rob Self-PiersonJoin us next Tuesday night, Dec. 23 0100 UTC (Dec. 22 8pm ET), when Rob Self-Pierson stops by to discuss his “MoonWalking” experiences and his upcoming Blue Moon Walk.  We’ll feature images, video, an interactive chatroom, and details about how you can participate in commemorating the last Blue Moon of this decade!

Look Up, Log In, or Listen: An Exciting Week of Astronomy!

Monday, October 19th, 2009

If you ever needed an excuse to go out and look up at the night sky, this week is it .  In fact, astronomy is so hot right now, you can even stay inside and enjoy many of this week’s events right from your computer!

meteors2

Moon-less Nights … First, the frosting on the cake (I always did like dessert, first) … We had a New Moon last Saturday evening!  That means a lovely crescent Moon at sunset and “moon-less” nights for darker skies!  Perfect timing for a week full of astronomy opportunities!

Moons You’ll Like … Jupiter’s Galilean satellites are putting on a show this week, with three occultations for eastern North America.  No doubt you’ve noticed Jupiter as that brightest “star” on your south horizon after sunset.  Even smaller binoculars will reveal the giant planet’s four largest moons, but you will need a telescope to fully appreciate the occultation events.

Shooting Stars … Those aren’t stars – they’re comet debris!  Heralding in this exciting week, the Orionids Meteor Shower is in full display right now.  Maximum occurs over the next three mornings, with peak expected on Oct. 21st (late Tuesday night / early Wednesday morning.)  Named for its apparent point of origin – the radiant is just east of Orion’s Betelgeuse – this shower is the second of two yearly passes through the debris trail of Comet Halley.  Currently, Orion rises around 11pm local time, so your best observing will be after midnight.  While the Orionids is not an especially prolific shower (20-30 zhr,) it is consistent and the streaks are distinctively quick and bright.  This year should offer an especially nice show with those moon-less nights.

Counting Stars … The Great World Wide Star Count winds down this week.  Counting stars is another activity best done on a moon-less night.  This citizen science event is a fun and easy way to learn more about the night sky, raise awareness about light pollution, and participate in the International Year of Astronomy 2009.

A Sky Full of Stars … On Wednesday evening, Rob and I will host a special edition of A Sky Full of Stars on AFM*Radio.  We’ll feature guests Adrian West, of the Newbury Astronomical Society (@NewburyAS), and young astronomer-extraordinaire Elias Jordan (@ksastro) to talk about some exciting upcoming astronomy events, including this year’s second Twitter MoonWatch and the IYA 2009′s  Galilean Nights.  The live show airs Oct. 21st at 8pm EDT (Oct. 22nd, 00:00 UTC)  – we’ll post the podcast version here and at Astronomy.FM.

Star-Filled Nights … Speaking of Galilean Nights, Astronomy.FM is celebrating with two special events this week.  First, they want to help you capture the stars with free imaging sessions from Global-Rental-A-Scopes.  Then, on Saturday evening, the Marleen Bryan and I will feature all things Galileo, with a special Galilean Nights edition of the DeepSkyDivas.  If you haven’t yet checked out Astronomy.FM, this is a good time to do it.  AFM offers an enthusiastic international community, a members forum, radio events, a daily Amateur Astronomer Picture of the Day (AAPOD), and regularly-updated space and astronomy news.  The DeepSky Divas airs, live, Oct. 24th at 9pm EDT (Oct. 25th, 01:00 UTC).

A Red Planet … While you’re out watching for meteors, see if you can spot the planet Mars, directly beneath Gemini’s Castor and Pollux.  Currently, Mars rises around midnight, about an hour behind Orion.  As you look at Mars, consider this – there are currently five crafts exploring our red neighbor.  Three crafts are orbiting the planet and another two are roaming its surface.

Morning Planets … Venus and Saturn grace the morning sky this week.  You’ll find the two together on your east horizon in the hour before sunrise.  Take advantage of this opportunity to see Venus before it leaves the morning sky next month.

Close Calls … Last but least  – this event is one that you can’t see, but it is something you’ll probably find very interesting.  Seventeen near-Earth-objects (NEO) will be passing our planet this week; thirteen were discovered just this year.  Seven of the seventeen will pass within just 10 lunar distances (LD) – the closest of those passed at a mere 2.5 LD last night!  Most of this week’s NEOs are smaller objects, measuring tens of meters wide.  Only two are considered larger objects, with the largest being 1.7 km – 3.8 km.

So, there you have it – opportunities to Look Up, Log In, and Listen – all with an eye on the stars!

Venus/Saturn Conjunction!

Sunday, October 11th, 2009

12VenusSaturnMercuryTomorrow’s sunrise sky offers a special treat for early risers.  Not only will four bright planets be visible, two of those planets will appear less than 1/2 degree from each other, and another will be less than 3 degrees from the waning crescent Moon.

Just before sunrise, watch for Venus and Saturn to rise as a pair on your East horizon, with Mercury rising very close behind.  Looking straight overhead, you’ll find ruddy Mars with a 38% illuminated Moon.  That bright star to the pair’s right is Canis Minor’s brightest star, Procyon; while the night sky’s brightest star, Sirius, is positioned just a little further right, or towards your West horizon.  Dropping straight down from Sirius, to your South horizon, you’ll find the 2nd brightest star in the night sky, constellation Carina’s Canopus.

Independence Moon

Monday, July 6th, 2009

Just a quick image of the near-Full Moon, on the cusp of our country’s Independence Day.  I’m glad I thought to grab this shot late Friday evening, as clouds, rain, and an eye on fireworks have since prevented any good images.  If you look closely along the terminator, you can see Crater Aristarchus peeking out from the dark.  (Click the image for a larger version.)

Capturing a spacecraft – LCROSS in Bootes!

Thursday, July 2nd, 2009

Yesterday, I was inspired by this video (posted on the SpaceWeather website,) to try for an image of NASA’s LCROSS craft as it passed through the constellation Bootes.  Not having my own imaging setup, I accessed the Slooh remote observatory off the coast of NW Africa and managed two images to create a short video.  Unfortunately, the imaging parameters at that particular observatory allow for images no less than ten minutes apart, so my video is not as good as I had hoped.  Nonetheless, it is an exciting experienced to have imaged a NASA spacecraft at such a great distance, especially one that will intentionally impact the Moon.  (You can click the image for the 2-frame animated version.)
