Deep Sky Colors - Astrophotography by Rogelio Bernal Andreo A video map of motions in the nearby universe ( —An international team of researchers, including University of Hawaii at Manoa astronomer Brent Tully, has mapped the motions of structures of the nearby universe in greater detail than ever before. The maps are presented as a video, which provides a dynamic three-dimensional representation of the universe through the use of rotation, panning, and zooming. The video was announced last week at the conference "Cosmic Flows: Observations and Simulations" in Marseille, France, that honored the career and 70th birthday of Tully. The Cosmic Flows project has mapped visible and dark matter densities around our Milky Way galaxy up to a distance of 300 million light-years. The large-scale structure of the universe is a complex web of clusters, filaments, and voids. Just as the movement of tectonic plates reveals the properties of Earth's interior, the movements of the galaxies reveal information about the main constituents of the Universe: dark energy and dark matter.

Astronomy Sky Condition This web site gives access to up-to-date meteorological forecasts in order to provide astronomers with information to plan their sky observation activities. The forecasts cover North America and are produced by the numerical weather prediction models that execute at the Canadian Meteorological Center.The following forecast parameters are available in real time: forecasts of cloud, surface winds, temperatures and humidity as well as more specific parameters such as seeing forecasts and sky transparency. Cloud forecastCloud forecasts at hourly intervals up to 48 hours.These forecasts can be interpreted in the same way as satellite pictures in the visible spectrum. Seeing forecastSeeing forecasts at 3-hourly intervals up to 48 hours. Sky transparency forecastSky transparency forecast at hourly intervals up to 48 hours.Observing deep sky objects such as faint galaxies and nebulae requires excellent sky transparency.

100,000 Stars How to Shoot the Night Sky (Introduction to Astrophotography) The following post on photographing the night sky is by jgomez65 – one of dPS’s forum members. Several people asked me to post a simple tutorial on how I took some night sky pictures. I am not an astrophotographer in any way, shape or form, nor do I have any expensive equipment. Anyway, here is how I did it. 1. You need a camera that has manual exposure mode. You will also need a remote control or a shutter release cable in order to minimize shaking the camera when taking the pictures. You will definitely need a tripod 2. The darker the place, the better it is. 3. First, try to use a lens with a large aperture. Next, set your camera at a high ISO. Finally, in order to avoid the star trail (that is avoiding capturing the movement of the stars as the earth rotates) you have to use the RULE of 600 which is very easy: Divide 600 by the focal length of the lens you are using. 4. Tip: Every time I am done with a set of pictures, I place my hand in front of the lens and take another picture. 5.

Hubble Telescope Reveals Deepest View of Universe Ever The Hubble Space Telescope has captured the farthest-ever view into the universe, a photo that reveals thousands of galaxies billions of light-years away. The picture, called eXtreme Deep Field, or XDF, combines 10 years of Hubble telescope views of one patch of sky. Only the accumulated light gathered over so many observation sessions can reveal such distant objects, some of which are one ten-billionth the brightness that the human eye can see. The photo is a sequel to the original "Hubble Ultra Deep Field," a picture the Hubble Space Telescope took in 2003 and 2004 that collected light over many hours to reveal thousands of distant galaxies in what was the deepest view of the universe so far. This image compares the angular size of the Hubble Extreme Deep Field survey to the angular size of the full Moon. The photo reveals a wide range of galaxies, from spirals that are Milky Way-lookalikes, to hazy reddish blobs that are the result of collisions between galaxies.

Nanaimo Clear Sky Chart It's the astronomer's forecast. At a glance, it shows when it will be cloudy or clear for up to the next two days. It's a prediction of when Nanaimo, BC, will have good weather for astronomical observing. The data comes from a forecast model developed by Allan Rahill of the Canadian Meteorological Center. CMC's numerical weather forecasts are unique because they are specifically designed for astronomers. But they have 763 forecast maps. So, I (Attilla Danko) wrote a script to generate the images like the one above which summarizes CMC's forecast images just for Nanaimo and the surroundings out to about 15 Kms. There are charts for 5162 locations. Summary: In the rows labeled "sky conditions", find a column of blue blocks. Details: Read the image from left to right. The line, labeled Cloud Cover forecasts total cloud cover. CMC's text page explaining this forecast is here. The line, labeled Transparency, forecasts the transparency of the air. This forecasts ground-level relative humidity.

Hubble zooms in on a space oddity | Press Releases A strange, glowing green cloud of gas that has mystified astronomers since its discovery in 2007 has been studied by Hubble. The cloud of gas is lit up by the bright light of a nearby quasar, and shows signs of ongoing star formation. One of the strangest space objects ever seen is being scrutinised by the penetrating vision of the NASA/ESA Hubble Space Telescope. A mysterious, glowing green blob of gas is floating in space near a spiral galaxy. The Hubble revelations are the latest finds in an ongoing probe of Hanny’s Voorwerp (Hanny’s Object in Dutch). In the sharpest view yet of Hanny’s Voorwerp, Hubble’s Wide Field Camera 3 and Advanced Camera for Surveys have uncovered star birth in a region of the green object that faces the spiral galaxy IC 2497, located about 650 million light-years from Earth. The greenish Voorwerp is visible because a searchlight beam of light from the galaxy’s core has illuminated it. Notes Links Contacts

Total Solar Eclipse 2012 photos, near Mount Carbine, Queensland, Australia November 14, Queensland, Australia Homepage Astrophotos Australia 2012 photos Purchase Photos! Total Solar Eclipse of November 14, 2012, as seen from a hilltop about 20 miles west of the Outback town of Mount Carbine, Queensland, along the Mulligan Highway (Peninsula Development Road), a road only paved in recent years. Heading inland to get away from coastal showers and clouds which were promising to interfere with the viewing, we drove some 150 miles into the outback to find a good spot the day before and settled upon a remote hillside, up along a dirt track that pulled away from the main road. The location was about 40 miles inland, and 67 miles from Cairns, as the crow flies. About 20 other cars camped out here as well under very dark skies. Astronomy Picture of the Day!

Le mystérieux bourdonnement de la Voie Lactée — Atra Materia Fr Posted on février 14, 2012 by Ashley Corbion . Des chercheurs viennent de découvrir un mystérieux « bourdonnement » au coeur de notre galaxie: elle émet une importante quantité de rayonnement micro-onde, et pour l’instant son origine demeure totalement inconnue. Aussi, de nouvelles « îles » de monoxyde de carbone froid ont été découvertes, aidant les astronomes à identifier les régions où se forment de nouvelles étoiles. Le satellite Planck a été lancé en 2009 avec pour objectif l’étude du fond diffus cosmologique, afin de délivrer des données plus précises que son prédécesseur WMAP. Planck ne se cantonne pas à l’étude du rayonnement micro-onde de l’Univers naissant, il établit également une cartographie précise recouvrant la totalité du ciel ainsi que notre galaxie. © ESA/Planck Collaboration Hier, lors d’une conférence internationale à Bologne en Italie, les scientifiques en charge de la mission Planck ont présenté les résultats intermédiaires de celle-ci.

Top 100 Astronomers You’ve Probably Never Heard Of How many of the faces above do you recognise? For a long time, I’ve wanted to investigate the the “who’s who” of astronomy via the literature but haven’t had the means. I’ve teamed up with Andy Casey who has written a neat ADS-python module to access the ADS publication database. It is still early days at the moment so we’ve mainly been brainstorming but we figured we should start with the basics: most cited astronomers. There will be more posts to follow as we have more ideas under construction. For this exercise I just needed the raw list of names and citation count. If you clone the initial script and simply add the following snippet, it will search Google images and download the first 3 images it finds. Then after using opencv to do facial recognition, one can extract the faces in the appropriate images. It must be said that though raw citation count is not necessarily and indicator of ‘the best astronomer’ it is one such measure the academic community uses to quantify “influence”.
