Ticking Stellar Time Bomb Identified [Cerro Paranal, Chile]

AndesEbla — Tue, 17 Nov 2009 13:10:58 GMT

Using ESO’s Very Large Telescope (Cerro Paranal, Chile) and its ability to obtain images as sharp as if taken from space, astronomers have made the first time-lapse movie of a rather unusual shell ejected by a “vampire star”, which in November 2000 underwent an outburst after gulping down part of its companion’s matter.

The expanding shell around V445 Puppis

Using the NACO adaptive optics instrument on ESO’s Very Large Telescope astronomers have made the first time-lapse movie of a bipolar shell ejected by a “vampire star”, which underwent an outburst after gulping down part of its companion’s matter. This enabled them to determine the distance and intrinsic brightness of the object. It appears that this system is a prime candidate to be one of the long-sought progenitors of the exploding stars known as Type Ia supernovae, critical for the study of dark energy. The images of V445 Puppis cover a time span of two years. The images unambiguously show a bipolar shell, initially with a very narrow waist, with lobes on each side. Two knots are also seen at either extreme end of the shell, which appear to move at about 30 million kilometers per hour. The shell — unlike any previously observed for a nova — is itself moving at about 24 million kilometers per hour. A thick disc of dust, which must have been produced during the last outburst, obscures the central couple of stars. The release [ESO Science Release 43/09], images and videos are available on:

Exoplanets Clue to Sun's Curious Chemistry (La Silla)

AndesEbla — Wed, 11 Nov 2009 19:35:49 GMT

"Dear all,

A ground-breaking census of 500 stars, 70 of which are known to host
planets, has successfully linked the long-standing "lithium mystery"
observed in the Sun to the presence of planetary systems. Using ESO's
successful HARPS spectrograph, a team of astronomers has found that
Sun-like stars that host planets have destroyed their lithium much more
efficiently than "planet-free" stars. This finding does not only shed
light on the lack of lithium in our star, but also provides astronomers
with a very efficient way of finding stars with planetary systems.

The release, images and videos are available on

Leonids and black holes

androseeker — Mon, 09 Nov 2009 07:56:32 GMT

I haven't seen much about the leonids here. Am I looking in the wrong place? Might be a really good show. Last one I saw, '02(?), was about 600 in three hours. Amazing! / Re: black holes (thank you John Wheeler), if a super-massive black hole is absorbing the mass of a galaxy, will it eventually cause the entire mass of that galaxy to gravitate inward and be totally absorbed? Is there a limit to how much it can accrete before it burps out a particle jet? "No thanks, I couldn't eat another bite.."

Flashback to summer

aries_poland — Wed, 04 Nov 2009 16:56:34 GMT

Summer in 2009 was wonderful to me, in terms of astronomy observations from my backyard :) I Observed all time I had on holiday - from end of June to end of August, of course when weather was good. Milky way, mythological constelations and short, bright nights, that was something magical! In that time, I maked few astro-sketches what I saw in telescope and binocular:

Forgive me, I'm not talented ;) Excellent polish astro-sketches you can see at this forum:

Gravitational Lens - Captured with Orion XX12i

Little Rock AFB — Sun, 25 Oct 2009 01:26:50 GMT

Amazing news (to me anyway),

The Orion XX12 telescope is "The Heat" as I was able to find the Gravitational Lens (Magnitude 15.5 !!) near Algenib in Pegasus. It was only a faint brown smudge...but I'm still floored I was able to see it!

I used a TeleVue 6mm Ethos. Love my XX12...hug!

SN 2009ig

DaveMitsky — Wed, 02 Sep 2009 18:07:21 GMT

A "bright" supernova, SN 2009ig, was discovered recently in NGC 1015, a 12th magnitude galaxy in Cetus. At 13th magnitude, this type Ia supernova should be fairly easy to see with a moderately large amateur telescope. An image is posted at http://astrosurf.com/jmllapasset/pubb/im_2009/2009_1/09igLL_C200908310242.jpg

A Supernova Duet in NGC 1448 from Cerro Paranal

AndesEbla — Wed, 21 Oct 2009 23:57:45 GMT

ESO picture of the week:

"Portrayed in this beautiful image is the spiral galaxy NGC 1448, with a prominent disc of young and very bright stars surrounding its small, shining core. Located about 60 million light-years away from the Sun, this galaxy has recently been a prolific factory of supernovae, the dramatic explosions that mark the death of stars: after a first one observed in this galaxy in 1983, two more have been discovered during the past decade.

Visible as a red dot inside the disc, in the upper right part of the image, is the supernova observed in 2003 (SN 2003hn), whereas another one, detected in 2001 (SN 2001el), can be noticed as a tiny blue dot in the central part of the image, just below the galaxy's core. If captured at the peak of the explosion, a supernova might be as bright as the whole galaxy that hosts it.

This image was obtained using the FORS instrument mounted on one of the 8.2-metre telescopes of ESO's Very Large Telescope on top of Cerro Paranal, Chile. It combines exposures taken through three filters (B, V, R) on several occasions, between July 2002 and the end of November 2003. The field of view is 7 arcminutes."

Ic 1396

steve421 — Mon, 19 Oct 2009 14:45:42 GMT

Hi All,

I was out last night doing some viewing, It was a pretty good seeing night under my moderate LP skies and I was looking for IC 1396. I first looked for u cephie (garnet star) and it didn't look red to me at all, but a bright didtant star. Under my LP skies I can just make out the house shape of cephieus, minus a corner star. Anyways I was able to see the star cluster of 1396, but no nebular. I tried averted vision and if I used my imagination I may have seen something, but can not be confident that I did. At one point I did see something move across the sky quite quickly which looked like a star moving so I think it may have either been a meteor or an asteroid, but it didn't stay in view long.

My question is this, I know I won't see the detail that are in the photos of ic 1396 but I would like to see the nebulae itself. I am using a 32mm eyepiece which gives me about 21x. Is this enough mag or should I go up? I am not using any filters although I will probally get the Zhumell kit advertised for $99. If anyone has any suggestions on how I may get a better view of nebulars I would really appreciate it. I right now am using a 60mm refractor. I know this is pushing the limits of the scope but right now I can not afford a better one.

Thanks for all your help

32 new exoplanets! From La Silla - Chile

AndesEbla — Mon, 19 Oct 2009 13:30:49 GMT

Today, at an international ESO/CAUP exoplanet conference in Porto, the team who built the High Accuracy Radial Velocity Planet Searcher, better known as HARPS, the spectrograph for ESO's 3.6-metre telescope, reports on the incredible discovery of some 32 new exoplanets, cementing HARPS's position as the world's foremost exoplanet hunter. This result also increases the number of known low-mass planets by an impressive 30%. Over the past five years HARPS has spotted more than 75 of the roughly 400 or so exoplanets now known.

On 19 October 2009, the team who built the High Accuracy Radial Velocity Planet Searcher, better known as HARPS, the spectrograph for ESO’s 3.6-metre telescope, reported on the incredible discovery of some 32 new exoplanets, cementing HARPS’s position as the world’s foremost exoplanet hunter. One of these is surrounding the star Gliese 667 C, which belongs to a triple system. The 6 Earth-mass exoplanet circulates around its low-mass host star at a distance equal to only 1/20th of the Earth-Sun distance. The host star is a companion to two other low-mass stars, which are seen here in the distance.

The Milky Way's Tiny but Tough Galactic Neighbour: Barnard's Galaxy [From La Silla - Chile]

AndesEbla — Wed, 14 Oct 2009 13:42:57 GMT

Today ESO announces the release of a stunning new image of one of our nearest galactic neighbours, Barnard's Galaxy, also known as NGC 6822. The galaxy contains regions of rich star formation and curious nebulae, such as the bubble clearly visible in the upper left of this remarkable vista. Astronomers classify NGC 6822 as an irregular dwarf galaxy because of its odd shape and relatively diminutive size by galactic standards. The strange shapes of these cosmic misfits help researchers understand how galaxies interact, evolve and occasionally "cannibalise" each other, leaving behind radiant, star-filled scraps.

A 340-million pixel starscape from Cerro Paranal Astronomical Observatory, Chile

AndesEbla — Tue, 22 Sep 2009 22:12:54 GMT

Fresh wonderful news from ESO (Chile): "The second of three images of ESO’s GigaGalaxy Zoom project is a new and wonderful 340-million-pixel vista of the central parts of our galactic home, a 34 by 20-degree wide image that provides us with a view as experienced by amateur astronomers around the world. Taken by Bes Stéphane Guisard, an ESO engineer and world-renowned astrophotographer, from Cerro Paranal, home of ESO’s Very Large Telescope, this second image directly benefits from the quality of Paranal’s sky, one of the best on the planet. The image shows the region spanning the sky from the constellation of Sagittarius (the Archer) to Scorpius (the Scorpion). The very colourful Rho Ophiuchi and Antares region features prominently to the right, as well as much darker areas, such as the Pipe and Snake Nebulae. The dusty lane of our Milky Way runs obliquely through the image, dotted with remarkable bright, reddish nebulae, such as the Lagoon and the Trifid Nebulae, as well as NGC 6357 and NGC 6334. This dark lane also hosts the very centre of our Galaxy, where a supermassive black hole is lurking. The image was obtained by observing with a 10-cm Takahashi FSQ106Ed f/3.6 telescope and a SBIG STL CCD camera, using a NJP160 mount. Images were collected through three different filters (B, V and R) and then stitched together. This mosaic was assembled from 52 different sky fields made from about 1200 individual images totalling 200 hours exposure time, with the final image having a size of 24 403 x 13 973 pixels. Note that the final, full resolution image is only available through Stéphane Guisard."

Hey, I'm pretty new in astrophotography and astronomy at all, few days ago I took 13 pictures of M13 in 30sec and stacked them with IRIS 5.5 Telescope I used http://telescope.bg/bg_celestron/img/c914sgtxltb.gif (ADVANCED C91/4-SGT (XLT) D235 F2350, f/10) and Canon 350D. So I wondered if these pictures are enough good for this technics or I can do pictures better, also after using software IRIS I did not use any other program to make photo better and even that it looks a little bit like I did it on photoshop. So please see and give your opinion http://photos-b.ak.fbcdn.net/hphotos-ak-snc1/hs194.snc1/6529_1033614257636_1743835481_58537_1896919_n.jpg thanx :)
