I want to see the Goldfish. Ok I spent five minutes looking for it until I re-read the press release and the bit about it being just out of view. Larger and full-res versions availble at the link below.
BTW, I LOVE the title from ESA for selfish reasons. LOL.
From ESA Spaceinimages (The Tadpole and the Wriggler):
A bright blue tadpole appears to swim through the inky blackness of space. Known as IRAS 20324+4057 but dubbed “the Tadpole”, this clump of gas and dust has given birth to a bright protostar, one of the earliest steps in building a star.
There are actually multiple protostars within this tadpole’s ‘head’, but the glowing yellow one in this image is the most luminous and massive. When this protostar has gathered together enough mass from its surroundings, it will eventually emerge as a fully-fledged young star.
Hubble’s latest look at comet C/2013 A1 (Siding Spring) on its way to a close encounter with Mars.
Hubble gives us this updated image of C/2013 A1 (Siding Spring). The image is all the better knowing the comet is somewhere around a magnitude 18 or so making it thousands of times fainter than we can see. Clicking the image will take you to Hubblesite. Clicking here will take you directly to the Comet C/2013 A1 (Siding Spring)image page at Hubblesite.
Comet Siding Spring is plunging toward the Sun along a roughly 1-million-year orbit. The comet, discovered in 2013, was within the radius of Jupiter’s orbit when the Hubble Space Telescope photographed it on March 11, 2014. Hubble resolves two jets of dust coming from the solid icy nucleus. These persistent jets were first seen in Hubble pictures taken on Oct. 29, 2013. The feature should allow astronomers to measure the direction of the nucleus’s pole, and hence, rotation axis. The comet will make its closest approach to our Sun on Oct. 25, 2014, at a distance of 130 million miles, well outside Earth’s orbit. On its inbound leg, Comet Siding Spring will pass within 84,000 miles of Mars on Oct. 19, 2014, which is less than half the Moon’s distance from Earth. The comet is not expected to become bright enough to be seen by the naked eye.

We are looking at a binary star system or rather what is left of a binary star system after one of the stars goes supernova. The surviving star is hidden the debris field of the supernova but it survived the explosion. I have to wonder what that star is going through, I’d be surprised if it wasn’t undergoing changes because of the explosion, I can picture siesmic waves ringing through it. We will probably never know for sure.
The image above is a composite of contributions from the Chandra X-ray Observatory and other telescopes including those in Chili and the Digitized Sky Survey.
There are desktop sizes to the image and they are wonderful! You can get them and read the details on DEM L241 here.
From ESA’s Space in Images this amazing Hubble image of the Monkey Head Nebula (in Orion) – the link has full-res versions of the image.
Hubble was launched on 24 April 1990, coming up on 24 years. The last servicing mission to Hubble was in 2009 which hopefully will extend the life of Hubble until 2021. I should note the expected life of Hubble after the servicing is published to be 2014 to 2021 – hopefully closer to the latter.
The James Webb Telescope is expected to launch in 2018.
About the image (from ESA):
Each year the NASA/ESA Hubble Space Telescope releases a brand new image to celebrate its birthday. This year, the subject of its 24th celebratory snap is part of the Monkey Head Nebula, last viewed by Hubble in 2001, creating a stunning image released in 2011.
Otherwise known as NGC 2174, this cloud of gas and dust lies about 6400 light-years away in the constellation of Orion (The Hunter). Nebulas like this one are popular targets for Hubble – their colourful plumes of gas and fiery bright stars create ethereally beautiful pictures, such as the telescope’s 22nd and 23rd anniversary images of the Tarantula and Horsehead nebulas.

The Interstellar Butterfly is Hubble’s Picture of the Week. Robert’s 22 is just another name for the nebula. This is what happens to a star like our own Sun as it ends its life. Stars of this size don’t blow up, rather they shed their envelopes and produce nebulae of various shapes and all beautiful.
The lobes in Roberts 22 have some outflows said to move at 450 km/s, that’s like a million miles per hour!
Pay a visit to the site and see a great archive of images.
Here’s the caption to the image:
They say the flap of a butterfly’s wings can set off a tornado on the other side of the world. But what happens when a butterfly flaps its wings in the depths of space?
This cosmic butterfly is a nebula known as AFGL 4104, or Roberts 22. Caused by a star that is nearing the end of its life and has shrugged off its outer layers, the nebula emerges as a cosmic chrysalis to produce this striking sight. Studies of the lobes of Roberts 22 have shown an amazingly complex structure, with countless intersecting loops and filaments.
A butterfly’s life span is counted in weeks; although on a much longer timescale, this stage of life for Roberts 22 is also transient. It is currently a preplanetary nebula, a short-lived phase that begins once a dying star has pushed much of the material in its outer layers into space, and ends once this stellar remnant becomes hot enough to ionise the surrounding gas clouds and make them glow. About 400 years ago, the star at the centre of Roberts 22 shed its outer shells, which raced outwards to form this butterfly. The central star will soon be hot enough to ionise the surrounding gas, and it will evolve into a fully fledged planetary nebula.

Nice! This is Herschel’s look at NGC 7538 a giant cloud of hydrogen and bits of dust – a stellar nursery. The dust also shines in the far-infrared which works out great for Herschel, ESA’s far-infrared space observatory.
Have a look at the Simbad page for NGC 7538 for a different view of it (optical I think).
Be sure to pay a visit to ESA’s Star factory NGC 7538 for the particulars.

Back on 23 January I did a post on the supernova in M82. Hubblesite just released a stunning picture of it. Wow, just look at that!
See the picture above and more at the Hubblesite.
The Hubble team have been watching hundreds of individual stars in the the Large Magellanic Cloud (LMC) over the past seven years and have mapped out their movements. What they got for their “trouble” is a precise measurement of the rotation of the galaxy! This is a first too.
The answer? The LMC rotates once every 250 million years, about the same as our solar system does in the Milky Way.

On 5 April and 20 May 2013 Saturn was on the receiving end of blast of solar wind. The electrons in the solar wind and collided with hydrogen molecules and an aurora resulted.
Between the Cassini spacecraft and the Hubble Space Telescope a series of ultraviolet and infrared images were taken and put into video form.
BTW: Snowing here, 300 to 360 mm expected overnight.
A new look at Centaurus A.Image credit: X-ray: NASA/CXC/U. Birmingham/M. Burke et al.
Centaurus A is always a treat to see in a good image. This Chandra image gives us an especially good look at those huge jets of material being rejected by the supermassive blackhole at the center of the galaxy.
This image shows those bubble structures too.
Just weeks after NASA’s Chandra X-ray Observatory began operations in 1999, the telescope pointed at Centaurus A (Cen A, for short). This galaxy, at a distance of about 12 million light years from Earth, contains a gargantuan jet blasting away from a central supermassive black hole.
Since then, Chandra has returned its attention to this galaxy, each time gathering more data. And, like an old family photo that has been digitally restored, new processing techniques are providing astronomers with a new look at this old galactic friend.
