I'm looking at Cartes du Ciel ( ) which might have that capability, but if so, I haven't yet figured out how to enable it.

Simply enter your location, either via zip code, city, or latitude/longitude, and find out what's up in your sky tonight Change the horizon view by dragging the green square on the full-sky chart. the latest night-sky events, astronomy news, astrophotography and observing tips. Chart the stars and planets visible to the unaided eye from any location, at any time of day or night, on any date between the years 1600 to 2400. Mercury keeps fading this week, from magnitude +0.2 to +1.0. As the sky darkens, Mercury will come into view about 8 above Venus as shown below. The first of them you may spot is Venus, bright at magnitude 3.9, very low exactly west-northwest. Unless otherwise stated, postage and handling charges are 5.00 for one item, 10 for 2 items and 15 for 3 or more items. This week, find Mercury and Venus low in the west-northwest in twilight.

I'd like to be able to specify a range of RA and declination and get that chart.Ĭan anyone suggest any free star chart printing software that can print similar output for any desired sector of the sky? current status check is already running. HOW TO ORDER: To order any of the products below, please call (02) 9439 1955 (9am to 5pm, Sydney time) with your credit card details handy, or use the order form in the current issue of Australian Sky & Telescope magazine. I like the general format of the Millennium Star Atlas - black stars on a white sky background, and with horizontal lines representing 1 degree of declination and vertical lines representing 4 minutes of RA (see sample page at ).

But there's such a richness of offerings that I'm having trouble figuring out which of those, if any, can produce printable charts in the format that I'm looking for. However, it is still only a fudge factor, and such things are inherently uncertain.I've been looking for sources of printable electronic star charts - there seem to be many different ones available, either as part of planetarium software or just plain charting packages. I think he did a perfectly reasonable job in deriving the best-guess fudge factor for this. 'He basically takes an observed luminosity-based, and thus already soft, mass estimate of 130 solar masses for a single star, and then applies some fudge factor to get 150 solar masses. 'My concern is the firmness which Figer attaches to his 150-solar-mass upper limit,' says University of Florida astronomer Steve Eikenberry. Find astronomy books, star atlases, solar system globes, and magazines all the astronomy resources you need to learn about and enjoy the hobby and passion of stargazing. 'The existence of a sharp cutoff has not been demonstrated observationally with such significance before.' 'The 100- to 150-solar-mass range has indeed been talked about as a limit for a long time, but theory does not derive it with any precision,' says University of California, Santa Cruz astrophysicist Stan Woosley. the bright star Pollux will appear 6 Sky and Telescope recommends trying. His result is consistent with studies of nine other young star clusters by a group led by Sally Oey (University of Michigan). listing the years observing highlights We start with a 1-day old Moon on. Comprising 8 laminated pages, each 23 x 33cm, it features: A. Adopting a conservative approach, Figer concludes that this 2-million-year-old cluster produced no stars greater than 150 solar masses. The latest edition of this fantastic Australian-produced lunar observing set is now available. The cluster, known as the Arches Cluster, resides near the galactic center and contains thousands of stars, some of which shine with millions of times the intensity of the Sun.

The most luminous (and hence most massive) stars in the cluster show a sharp cutoff in initial mass at about 130 solar masses. To fix this, clear your local DNS cache to make sure that you grab the most recent cache that your ISP has. In the early nineties ASRB published a small rotational sky chart for amateur use. Figer (Space Telescope Science Institute) presents Hubble Space Telescope observations of the richest young star cluster in the Milky Way Galaxy. SKYANDTELESCOPE.COM OBSERVING SKYCHART FULL. Such design was good enough for amateur observations until mneties. In a paper published this week in the British journal Nature, Donald F. Now, astronomers have observational evidence that this thinking is largely correct. Stars above this mass limit should generate so much light that the sheer pressure of their own radiation blows off enormous amounts of mass, quickly whittling them down to 100 to 150 solar masses. In recent decades, many astronomers believed that limit was somewhere in the neighborhood of 100 to 150 solar masses for stars forming in the modern-day universe. Advertising Information Sky & Telescope MagazineĪstronomers have long wondered what is the upper mass limit for stars.
