Jupiter through a 150mm F5 telescope Astronomy and Astrophotography are amazing when getting good weather. Here we see Jupiter at 2009-07-28 03:33 UT. The Great Red Spot (GRS) is visible near the center of the planet. First sequence shows Jupiter crossing the field because of sideral motion. Second sequence shows Jupiter centered in the FOV after aligned with Registax 5. Final sequence shows the Jupiter resulting picture after stacking every subframe and doing some post-processing with Paint Shop Pro 9. The effective resolution reached may be near 1 arcsecond, and it is almost the maximum resolution available for such kind of telescopes. More info at

Hubble Update 10 {2nd of June 2010}: Restless Star Cluster NGC 3603 One of my favourite places in the Universe, NGC 3603 is a stunning stellar cluster with many secrets to be unfolded like the one in this video. Here's the update: 02-June-2010 By exploiting the exquisite image quality of the NASA/ESA Hubble Space Telescope and comparing two observations made ten years apart astronomers have, for the first time, managed to measure the tiny motions of several hundred young stars within the central cluster of the star-forming region NGC 3603. The team was surprised to find that the stars are moving in ways that are at odds with the current understanding of how such clusters evolve. The stars in the cluster have not "settled down" as expected. With a mass of more than 10 000 suns packed into a volume with a diameter of a mere three light-years, the massive young star cluster in the nebula NGC 3603 is one of the most compact stellar clusters in the Milky Way [1] and an ideal place to test theories for their formation. A team of astronomers from the Max-Planck Institute for Astronomy in Heidelberg and the University of Cologne led by Wolfgang Brandner (MPIA) wanted to track the movement of the cluster's many stars. Such a study could reveal whether the stars were in the process of drifting apart, or about to settle down. The cluster, formally known as the NGC 3603 Young Cluster, is about 20 000 light-years from the Sun which makes these measurements extraordinarily difficult. It is necessary to compare images that were made years or even ...
Titan Occulting Binary Stars (NV0435215+200905) - Faster clip See more at "What might look like Pac Man swallowing a dot is actually Saturn's moon Titan occulting (passing in front of) a binary star system (named NV0435215+200905).

Because fantastic resolving power of the Hale using adaptive optics you can see that the light of the star nearest to Titan is being refracted by Titan's dense atmosphere. Such events are rare, but valuable. The starlight as it is seen passing through Titan's atmosphere is essentially a probe providing clues as to the density, temperature and wind patterns of this distant world. The team of astronomers (Antonin Bouchez, Michael E. Brown, Mitchell Troy, Rick S. Burruss, Richard G. Dekany and Robert A.

Sun raises 2 days early in Greenland. Due to Glacial Melting (Lower Horizon) ? The latest thing going around the internet today is that the Sun rose on in a small burg called Ilulissat in Greenland on January 11th. Ilulissat is north of the arctic circle so it experiences 24 hours of darkness for several weeks. Nothing unusual there. The unusual part is that the Sun usually rises again on January 13th. Therefore, the Sun came back two days early and the question is why. The first thing to do is to verify the claims is true. I checked out the NOAA Sunrise/Sunset calculator (after finding what I think is the lat/long of Ilulissat. There are lots of places with similar names in Greenland!) and the US Naval Observatory. Sure enough, January 12th, no sunrise. January 13th, there is a sunrise and a very short day. Okay, NOAA and USNO agree with the prediction and they are pretty reputable in such matters. The next thing is to verify the observation. This part is much trickier. The story has gone viral on the web. The best I can tell, it started with a story in the Daily Mail. Read it and you can see the details of who made the observations and where are pretty sketchy...okay, non-existant. No mention of the time of the observation, how long the Sun stayed up, location of observation, azimuth of the Sun (I don't consider the stock photo they used in the story to have any bearing on anything) or who made the observation. A photo of the sunrise with an identifiable landmark would have been REALLY useful! Now on to the possible why (assuming it really ...

2000 Light Years From Home The light-year is often used to measure distances to stars and other distances on a galactic scale, especially in non-specialist and popular science publications. The preferred unit in astrometry is the parsec, because it can be more easily derived from, and compared with, observational data. The parsec is defined as the distance at which an object will appear to move one arcsecond of parallax when the observer moves one astronomical unit perpendicular to the line of sight to the observer, and is equal to approximately 3.26 light-years. However because infinity goes in both directions growing larger or shrinking smaller "4-D" is used as an abstract concept derived by generalizing the rules of three-dimensional space. It has been studied by moronic mathematicians and philosophers for almost two hundred years, both for its own interest and for the insights it offered into mathematics and related fields. Algebraically it is generated by applying the rules of vectors and coordinate geometry to a space with four dimensions. In particular a vector with four elements "a 4-tuple" can be used to represent a position in four-dimensional space. The space is a Euclidean space, so has a metric and norm, and so all directions are treated as the same: the additional dimension is indistinguishable from the other three. In modern physics, space and time are unified in a four-dimensional Minkowski continuum called spacetime, whose metric treats the time dimension differently from the three ...
Albert Michelson 20-foot Interferometer Albert Michelson measured the diameters of Jupiter's moons by interferometry in the early 1890's in order to test the technique. Using the 12-inch refractor at California's Lick Observatory he covered the lens with a large screen that had two holes ("pick-off points") at separations of up to 12 inches to simulate different baselines. The diameters of the satellites were determined to be on the order of one arc second, which is approximately correct. By 1919, knowing that the diameters of stars appeared much smaller because of their great distances from Earth, Michelson and Francis Pease designed and built the 20-foot Stellar Interferometer. Here the 20 feet refers to the maximum baseline of the pick-off mirrors. It was installed atop the 100-inch telescope (shown above), the largest telescope in the world at the time. The maximum baseline possible was 20 feet because anything longer would hit the interior of the dome as the telescope moved from one part of the sky to another. The design of this instrument and the perforated screen used at Lick Observatory were the idea of the French scientist Hippolyte Fizeau (1819-1896), who was also the first person to measure the speed of light in a laboratory. In effect, the 100-inch telescope was being used as a large and stable optical bench capable of being pointed at different parts of the sky. The 100-inch telescope has a long history of being used in this way -- the natural guide star adaptive optics instrument on the 100-inch ...
Evidence of an Old Universe - The Light Echoes of Supernova 1987a - p4. Conclusions References: The main source I used for the method and maths used to calculate the distance to Supernova 1987A was: articles.adsabs.harvard.edu That article is referenced by Wikipedia in it's main article on SN 1987A which is: Two more wikipedia articles used in the making of these videos were the one on the speed of sound in air: and the one on the speed of light: No wikipedia articles were harmed during the making of this video. I departed quite a lot from my original script in these videos. I also had a problem with the length, I thought I could explain everything in two videos, but in the end it took 4 and I may add two more if these get a positive response (I think they are my best videos yet, not for the style, but I am very happy with the content). If I do add two more videos one will be a kind of trailer, or summary, and the other will go into further details for those who want more of the story. Anyway, for what it's worth, here is the section of the original script matching this video, but it's not a good match for what I actually say: The astronomers also measured the angular magnitude of the rings radius as about 0.81 of an arc second. Thats a very small angle. Each degree is divided into 60 arc minutes and each arc minute into 60 arc seconds. So 0.81 arc seconds is less than one 4000th of a degree, or more accurately its: 0.000225 of a degree. My thumb is about 2.5 cm across so it would have to be about 6.4 Km ...

Jupiter-4-25-05-01ll.avi Retrospective look at the planet Jupiter as the Great Red Spot is transiting. To the right of Jupiter, you may see a tiny Galilean moon popping into and out of view. This is caused by atmospheric instability that causes the resolution of the image to drop below 1 arc second, which is the apparent diameter of the moon. When this happens the image of Jupiter becomes blurred as well, and details smaller than 1 arc second are lost temporarily. 1 arc second is about 1/40th the apparent diameter of Jupiter when viewed from earth. This video was made with a Celestron C8 Schmidt-Cassegrain reflector at f/10. The image was captured using a Phillips webcam adapted to sit in the focal plane of the telescope.

Aero-TV: Avionics Tip Of The Week - Aspen 2.2 Software Upgrade Latest Revision Adds New Capabilities Aspen Avionics introduced version 2.2 software for its popular Evolution EFD at the 53rd annual AEA Convention and trade show in April, adding some new user-friendly features that increase functionality and decrease ***pit workload. Brad Hayden, Aspen's Vice President for Marketing, said that company is now starting to take its "product roadmap" to the next step, building new products for new markets based on the EFD1000 hardware and software, with both the fixed and rotary wing markets showing interest. The version 2.2 software for EFD1000 will include some significant new features, including navmap panning. The feature uses a "gunsight" which the pilot can place over an object or non-object and retrieve information about the targeted item. A second panning function allows scrolling off the map being displayed. Hayden said there are now multiple paths to the same information. For those pilots who prefer to go through the menus to get information, they can still do that, or use the "gunsight" panning function. "One of the things we really strive to do," Hayden said, "is build a product that conforms to the pilot, and not the other way around." Later this year, Aspen plans to start shipping a backup display, which is essentially an EFD1000 in landscape orientation. It will include seven backup "instruments" in one unit, including attitude, altitude, airspeed, VSI, HSI, GPS flight plan, and GPS steering. Aspen also plans to make a ...

Millennium Simulation: "The Largest Model of Our Universe" The most current estimates guess that there are 125 to 200 billion galaxies in the Universe, each of which has hundreds of billions of stars. A recent German supercomputer simulation put that number even higher: 500 billion. In other words, there could be a galaxy out there for every star in the Milky Way.. The Millennium Run simulation starts with the initial state of the Universe, where the Cosmic background radiation was created. Its properties are well known by satellite experiments and serve as the starting point for the corresponding matter distribution. Using the physical laws of the currently known cosmologies, the evolution of matter as galaxies and black holes is simulated and recorded. This simulation was created and executed for the first time in 2005 by the Virgo consortium, an international group of astrophysicists from Germany, the UK, Canada, Japan and the USA. PLEASE READ: I screwed up! The Andromeda Galaxy is our closest: "spiral galaxy" (like our galaxy). Canis Major dwarf galaxy is the closest galaxy to the Milky Way. The three nearest known stars are gravitationally bound in a system commonly called Alpha Centauri. The two larger stars, said to be Sun-like, are named Alpha Centauri A and B. The nearest to us is the littlest and is called Proxima Centauri. It is classified as a red dwarf and contains just a fraction of the mass of our Sun. The three-star system is 4.36 light-years away, meaning light requires 4.36 years to travel from the stars to ...

Permutations and Derangements This video asks a question in simple combinatorics and works towards the answer, deriving a recursion relation for the number of ways to order n soldiers, when none is allowed to go in their correct position. The recursion relation is D(n) = (n-1)(D(n-1) + D(n-2)) To explore this problem beyond the simple recursion relation, see my related blog post:
Simulation of our Universe showing in large scale The Virgo consortium, an international group of astrophysicists from the UK, Germany, Japan, Canada and the USA has today (June 2nd) released first results from the largest and most realistic simulation ever of the growth of cosmic structure and the formation of galaxies and quasars. In a paper published in Nature, the Virgo Consortium shows how comparing such simulated data to large observational surveys can reveal the physical processes underlying the build-up of real galaxies and black holes. PLEASE READ: A parsec (symbol pc) is a unit of length used in astronomy. The length of the parsec is based on the method of trigonometric parallax, one of the oldest methods for measuring the distances to stars. The name parsec stands for "parallax of one second of arc", and one parsec is defined to be the distance from the Earth to a star that has a parallax of 1 arcsecond. The actual length of a parsec is approximately 3.262 light-years. the Andromeda Galaxy is 0.77 Mpc away from the Earth. the nearest large galaxy cluster, the Virgo Cluster, is about 18 Mpc away from the Earth. the galaxy RXJ1242-11, observed to have a supermassive black hole core similar to the Milky Way's, is about 200 Mpc away from the Earth. the particle horizon (the observable part of the universe) has a radius of about 14 Gpc. One gigaparsec (Gpc) is one billion parsecs — one of the largest distance measures commonly used. One gigaparsec is about 3.262 billion light-years.
