Are there any good websites to watch astronomy documentaries online?

Posted in Astronomy on March 29th, 2010 by admin

I love watching astronomy shows about things like the big bang or black holes on the science and discovery channel. Is there a website where I can watch documentaries like this?

Youtube: This channel has plenty of Astronomy videos : http://www.youtube.com/profile?user=Zuke696&view=videos

Very Large Telescope

Posted in Telescopes on March 27th, 2010 by admin

Every night, all year round, the ESO Very Large Telescope, or VLT, opens its four giant eyes to scrutinise the beautiful southern skies. Each eye is a huge mirror, 8.2 metres in diameter, that gathers the light of the night sky, and reflects it into optical systems that form ultra-sharp images of the Universe. But keeping the VLT’s eyes clear requires each mirror to be cleaned and recoated occasionally, a delicate and complex procedure.

What Device do largest telescopes in world use to collect as much light as possible?

Posted in Telescopes on March 22nd, 2010 by admin

The largest visible-light Telescopes in the world use what device to collect as much light as possible before the light is brought to a focus (to act as the light bucket)?

A. a lens
B. a spectroscope
C. a CCD
D. a mirror
E. a valley in Puerto Rico

a mirror.

How can I get people to appreciate astronomy more?

Posted in Astronomy on March 22nd, 2010 by admin

I’m in the 6th grade. I love astronomy, but no one else seems to appreciate it. Can you help?

You could join a local astronomy club, or start one at your school (but there’s usually one in most communities). Those guys (and a few gals) usually have some pretty cool Telescopes and are happy to teach people about Astronomy.

Spitzer Space Telescope: The Musical

Posted in Telescopes on March 20th, 2010 by admin

A singing NASA supervisor uses song to explain about NASA’s Spitzer Space Telescope, and how infrared Astronomy differs from visible-light Telescopes like Hubble. Starring Danny Tieger (“My Universe Revolves Around You”), Buffy Henshaw (“Behind the Scenes: When Galaxies Collide”), and Tom Phillips as Flunky #2.

NASA’s Spitzer Space Telescope

Additional imagery sources include:
Hubble Space Telescope
Chandra X-ray Observatory
_________________________

LYRICS:

Spitzer was launched in 2003
The 4th of NASA’s Great Observatories
On an Earth-trailing orbit with its back to the sun
3 eyes to the sky with coolant for one.
Its 66 million miles away
Because the heat from the Earth would affect the display
Were talking sensitive instruments, keep it streaming on course
for its deep space heat-tracing gaze at the Universe

CHORUS
Infrared
Capturing the heat instead
There is light form the sky that we can’t see
In the darkest parts of the galaxy
With Spitzer’s spectrum
We can detect them
Easily

Spitzers greatest gift to the viewing community
s the ability to see through the dust clouds that literally
Block the view of other telescopes
Unless that dust gets busted they stand no hope
Of seeing what we can, Were NASAs greatest addition
But you didnt hear it from me ’cause it aint a competition,
Yeah, were working together, combining forces for the mission
of a better sense of interstellar cosmic composition

CHORUS

Visible light Visible light
We can only see the stars if the stars shine bright
Infrared, (yeah) infrared
Depends on the energy in heat thats shed.

Spitzers pulling pictures like the paparazzi
Though the coolant ran out, so we cant use all three
Weve got notable photos, and even bros know it shows
The secrets of Universe are fully exposed
Like some extrasolar planets, does get you a going
‘Cause the heat from those planets has its own faint glowing
If there are half as many planets around the stars weve found
Its a million times more likely theyve got life spinning ’round
Am I blowing your mind? Are you listening to me?
Were the white coat crew that mapped our galaxy
So youre joining the team, thats hot in the head
Hooked on looking for the cooking bits of orange and red.

CHORUS

Astronomy in the Tetons

Posted in Astronomy on March 20th, 2010 by admin

Headed south and managed to find a great secluded spot for astro in the Tetons.

Friday 21th Aug 2009
After much thought of whether to head onto Butte or back to Great Falls, Falls won, simply as I new the lay of the land there. I knew there was a walmart which was the first stop to buy a portable hairdryer. Second was onto starbux where I rendered and uploaded another movie. Shortly after midday I started the trek down to Butte. When I got there I was disappointed to find the Sears I was heading to had no auto. Picked up fuel and food and headed on down to Idaho falls. Got there about 6pm and was surprised that their sears was still going. Got an oil change and tyre rotation (up to ca 10k miles). Then onto the pass of the tetons where I hoped to find a nice observing site. I got VERY luck and found a fantastic place. There are two passes between Idaho Falls and Jackson. The first and smaller one was the one I stopped on and was surprised to find a good quality dirt road leading out back (thats great as it got me off the main road, which turned out to have traffic on it throughout the night). Set the scope up and collimated. Jupiter looked good and the seeing, while showing some turbulence was pretty good. By midnight the milkyway formed a glowing arch over the velvety black celestial sphere. I set the camera up firstly on andromeda, then moved to M33, the triffid nebula and M51. After that I was getting tired and so set up the timelapse on Jupiter (taking a frame a second). The tracking was still slipping periodically and I had to somewhat babysit the tracking. The terrain was not good for the night wanders and hunters in that it was open and very still, such that it was impossible to approach without making noise in the dry grass. However one incident got me out of my chair quickly. Initially I heard a sound like something big breathing, but wasnt certain, then a few seconds later something like a large snort a hundred or so meters away. I scanned the surrounding eagerly and purposefully, ready at a second notice to head for the security of the car, but my flashlights revealed nothing and I heard nothing else. Then about 4ish there was a multitude of howling across the valley, the night hunters were at work, and moving around too, I could hear the canine vocalization moving around the tree covered hills opposite. There are wolves in the tetons, and I was alone on a hilltop. Orion rose brilliantly just before dawn, and as the seeing on Jupiter was now terrible I gave it a go, and for only the second time in my life, I captured the horsehead nebula! Also took a brief look at Mars and Venus, but one was rather small, and the other rather bright. By then the sky was lighting up with vibrant pastel colors and I packed up and headed down to the pass carpark where I looked for a place that would get some shade from the firey sun that would soon rise, and I went to sleep just before dawn.

Saturday 22th Aug 2009
Back to Idaho falls and spent day processing piccies of timelapse. Had taken a piccie per second with the webcam, and using registax 20-40 frames gave a very good result. However was it labor intensive. I couldnt figure out any way to automate it (well I could have done, but if its a one off, writing the automation would take longer than just doing in the labor intensive way. The result blew away previous results, but by the time I was finishing up it was dusk in Idaho falls. By chance there was a walmart out back of the starbux so I just went for a wander (I was tired after a day of CPU work) and to my surprise found something that would do the AV record for the plane only 80 bux too! I bought it (last one) but after an hour or so of messing with it in the car worked out that it wouldnt sync up with the feed. Plus it died with loss of signal (same as the HD aiptek). Headed back to the pass but it was seeing (a good thing too as I was not really in any state to do anything). Slept on pass I had done the astro on the night before.

What are the different types of land based telescopes and space telescopes?

Posted in Telescopes on March 15th, 2010 by admin

I ma doing this for science coursework. I ened it by the the end of this lesson
what are the different types of land based telescopes?
what are the different type sof space telescopes?
please help!

When we observe, we usually observe a portion of the electromagnetic spectrum.

Ground Based Telescopes — Are easy to build, but hindered by the fact that much of the EM spectrum is blocked by the earth’s atmosphere:

Radio Telescopes — Observe Radio Waves. These are the "big dishes out in the desert"
Submilimeter Telescopes — Observe just above radio waves.
Optical Telescopes — These are what live in domes. There are two main types:
     Reflecting Telescopes — Use giant mirrors. These are the only "large" modern telescopes, and are being built with single mirrors as large as 8.6 meters and multiple mirrors as large as 30+m.
     Refracting Telescopes — These use lenses (like a spyglass or binoculars). These have fallen out of favor, as they are hard to build and introduce problems in the incoming light. The largest in the world in only about 40 inches.

Unlike ground based telescopes, space based telescopes can observe all the bands, including those that don’t penetrate the earth’s atmosphere.

Space Based Telescopes:

Radio — None currently deployed
Infrared — Detects "heat" from distant object
Optical — Takes pictures. Example: Hubble. These are all reflectors, there are no (major) space based refractors.
Ultraviolet — Just above the optical band.
X-Ray/Gamma-Ray — These are super high energy particles from stars. They can only be observed from space, as our atmosphere blocks them.

Finally, stretching the definition of telescope, there are super giant tanks of extremely pure water (or other compounds) buried miles under the earth’s surface. These can be used to detect non-electromagnetic radiation (neutrinos). These aren’t telescopes, per se, but they can detect the outpouring of neutrinos from fusion in the hearts of stars.

What are some astronomy projects I could do?

Posted in Astronomy on March 15th, 2010 by admin

I am going to do a science project for a scholarship and I’m not quite sure what I want to do. I really like Astronomy so I think that would be fun. It can be biology, earth science, or astronomy (anything that’s natural). Do you have any suggestions on a project I could do preferably an astronomy one?
