Supernova Imaged by Hubble Telescope
Delta Vel writes "First discovered by a Japanese amateur astronomer on July 31, this Type II supernova was imaged by Hubble on August 17th. The newly named SN 2004 dj, the closest supernova to be observed in over ten years, is about 11 million light-years away in the spiral galaxy NGC 2403. Looks like they goofed in one of the images, though--the arrow points to a different bright spot on the before-and-after image than it does on the main and annotated images." Reader Saeed al-Sahaf writes "Today, astronauts Gennady Padalka and Mike Fincke popped open the hatch on the Russian side of the ISS spacecraft and quickly stepped through the fourth and final spacewalk of their six-month mission. Their mission? Install three antennas and replace a 2-foot-square Russian pump panel. But of course, because it isn't a part or our Mission to Mars, it is still too dangerous work on the Hubble Telescope, which after all, is only used for science."
It's about time they got a bittorrent server in space.

The RIAA is now building a rocket which can be sent into space to deliver a cease and desist order to supernova to stop piracy once and for all.
I wonder if they'll put a bittorrent link to the image of the supernova on a certain bittorrent website
HALLO I R KOREA my name is Kim Sun-il, and this past June, my head was brutally removed by jihadis. Some of you may be thinking, "but I'm not in Iraq, and I opposed Bush's war!". Do not take any comfort, as my fate may soon be yours anyway. Filthy towelheads make no distinction between left and right, only Pious and Infidel. If the sandniggers are not destroyed, they will lop off your junk off liberally in due time. Treat the muslim with the same pwnage that the Japanese used to inflict on us and the chinks. Nuke their holy cities, butcher their children, and rape their women. Only then will the world be safe for you and your Starcraft-playing brethren. Thank you for listening-

Hi there
They'll put any old thing up, this happened 11 million years ago for God's sakes.

Every time I see or type "supernova", I thing/type "suprnova" after Suprnova (dot) org
No sig, sorry.
The Suprnova stronly resembled a large collection of pirated games, moveies, and Television shows. Later confirmation sightings revealed it to be not in fact Suprnova, but only a mirror.
Even those who arrange and design shrubberies are under considerable economic stress at this period in history.
UC Berkeley's NewsCenter has a nice article about this. The astronomer is from UC Berkeley.
Suprnova has been teh f0unD?!?!? We are d00med!
Everyone into the escape boat! Women and children (heh, heh, heh) first!!!
AHA! CONSPIRACY! This also means we didn't actually land on the moon, and lends credence to my little-green-men-at-roswell theory. Not the alien autopsy though, that was just nonsense.
Please help metamoderate.
CAPE CANAVERAL, Florida (AP) -- Leaving their orbiting outpost unmanned, the international space station's two astronauts floated outside on a spacewalk Friday and plugged in new antennas and replaced a worn-out piece of cooling equipment.
Gennady Padalka and Mike Fincke popped open the hatch on the Russian side of the spacecraft and quickly stepped through the fourth and final spacewalk of their six-month mission.
Their job: install three antennas for a new type of cargo carrier to be launched by the European Space Agency to the space station late next year and replace a 2-foot-square Russian pump panel, part of a critical system for cooling station equipment.
"Be careful," Mission Control repeatedly warned the spacewalkers, telling them something like snow might float out when the 6-year-old pump panel comes out. "Go slowly."
The new pump assembly went into Taco's rectum neatly. Then the spacewalkers installed a few hooks on exterior handrails, for use during spacewalks. The antenna job followed; the men tossed antenna covers overboard as they connected the three devices, one by one.
Because no one was left inside the 225-mile-high complex, flight controllers in both Moscow and Houston kept close watch over the two men and all systems.
NASA prefers having a crew member inside during spacewalks but has had to settle for one less person on board for more than a year because of the grounding of the shuttle fleet. This was the fifth spacewalk with an empty outpost.
The space station has been relying on Russia's much smaller spacecraft for deliveries ever since Columbia broke apart over Texas during re-entry on February 1, 2003, lol @ Columbia.
Padalka and Fincke have just 11/2 months remaining aboard the space station before they return to Earth. They will be replaced by another Russian and American.
During Friday's outing, flight controllers hoped to better understand the mysterious force that tilted the space station 80 degrees off-center during the men's last spacewalk, one month ago.
Engineers suspect the extra force could have come from air gushing out when the hatch was opened, or from the spacesuits themselves.
To test those theories, Mission Control had the spacewalkers remain as still as possible for 15 minutes in an "junktouch experiment."
As Padalka and Fincke hunkered down and tried to be motionless, they asked flight controllers to talk to them so they wouldn't get bored.
"You want news?" Mission Control asked. "It is raining in my pants." The chitchat went on, and on.
About 31/2 hours into Friday's spacewalk, well after the astronauts' junktouch test, one end of the space station pitched slightly upward like an erect penis, Mission Control reported. As they did during last month's tilt, the U.S. gyroscopes reached their stabilizing limit and Russian thrusters had to take over control of the complex, officials said. None of this disrupted the spacewalk.
Even better on an intergalactic level.
I'm kind of disappointed though. I was hoping it would be background worthy.
"He does look a bit Oompa like, even if his Loompa is a bit off-kilter."
Really, the first thing I saw when I read the headline was "Suprnova Imaged by Hubble Telescope." I had to read the blurb a couple of times to realize that the article is about Astronomy, not the proliferation of software piracy.
Suprnova is a great site. But we dont need to make it any slower :p.
"Looks like they goofed in one of the images, though--the arrow points to a different bright spot on the before-and-after image than it does on the main and annotated images."
I don't think so. Looking at the pics its the same one in both. I think the submitter is confused as there is a large similar looking nebula in the south-east (bottom left, which *is* south-east)
Science is a crucial part of any space program, and this should continue. But space has never been exclusively for science, and it never should be.
If we divide up the universe between the space scientists and space colonists:
Science: The universe
Colonization: Earth, Earth orbit, Moon
(Mars is disputed territory.)
Now, the colonists want to return to the moon and go to Mars, with robots and humans, with the aim of colonizing both worlds. The scientists want to understand the universe. Both goals are worthwhile.
I'm in favor of repairing the Hubble telescope, but any deaths will give Congress an excuse to shut down the space program. Robotic repair is a good compromise.
Not for the dialup dudes, but great for broadband buddies:

it's liek, fool of stars!!111111111111oneoneoneone
The way I understand it, a super nova would explode like a nuclear bomb in the air, that is, in all directions, so shoulded the upper right image be the correct one? Nebulas are like the foreground objects, often like wisps of fog. They are either the birthing ground of stars or a _long_ ago remnant of a super nova.
...because it is in another galaxy.
If it were in our own galaxy then it would have a chance of being visible.
Who farted?
"full_jpg.jpg" Who comes up with this shit?
Whoever shot this image should retake photography class and learn not to use such high ISO's on the Hubble when shooting in the dark. Its so grainy, even my 2mp camera takes better pictures.
They arrows are fine... You just have to realize that the first images have the majority of the galaxy cropped out... They are only showing NGC 2403-1, instead of the large NGC 2403.

Propz to the Nasa guys for marking some of the images with the earths relative polar position. This should come in handy if I ever get lost in space!

What I would want to see is one that lights up the night as if it were day. Heard that happened once, would love to see it with my own eyes.
Fly me to the moon Let me sing among those stars Let me see what spring is like On jupiter and mars
Anyone else kinda glad that the supernova in question is in a "nearby galaxy" (nearby is a relative term, obviously) rather than our galaxy? If it can be mistaken for a local star at that distance, imagine what it would be like up close and personal.
Well, I guess it's only another 5 billion years til we get to see one REALLY up close.
Bored? Visit my exciting counter page!
Messier object 1 (M1), more commonly known as the Crab Nebula, is a good example of a "Long ago" supernova remnant.
Crab Nebula Info
The star went supernova almost a thousand years ago, and that is whats left.
During the actual event of a supernova, though, the star (from so far away) only seems to go from being a normal star to an amazingly bright one, and then slowly dimming down over a few months (or years). The reason is because stars are so huge they cannot simply explode like in the movies, after all they are in a constant state of nuclear fusion!!
-Bill
Type Ia supernovae take about a month to reach their peak brightness. While this is a Type II, a different class of explosion, I think the timescale is comparable. Accoring to this page the supernova had an apparent visual magnitude of 11.3 in early August. This is a factor of 100 dimmer than the naked eye can see under the best conditions (magnitude 6 is the dimmest the unaided eye can see).
If you're unsure of why a higher number means a dimmer object, or just want more information, czech out the Wikipedia entry on visual magnitudes.
By the way, the last supernova that was visible to the naked eye was SN1987A in the Large Magellanic Cloud.
I would rather be killed by a terrorist than enslaved by my government.
If it really appeared as bright as the sun, but was coming from a star-sized pinpoint in the sky, that might be a little hard on the retinas if you looked at it directly.
Now, in the event you notice that the entire upper atmosphere has been turned into an orange smog by the gamma rays, then you know that the supernova was really too close for comfort. In that case, head down to your basement for a few years until the ozone comes back.
The rate of occurrence of supernovae in our own galaxy is now reasonably well determined to be one every 25 years. Supernova remnants in our own Galaxy and nearby galaxies are theoretically observable for over a million years.
I wonder what the residents of that now-ex-solar system thought? And perhaps that'd be a good section of the sky to look for messages in? Perhaps they saw it coming, and could only save "themselves" by broadcasting their technology to any civilization that could make use of it.
I feel fantastic, and I'm still alive.
You know there's something seriously wrong when you type in Supernova in Google and it asks you "Did you mean : Suprnova " ?
Too late for that. The message would have had to leave before the supernova, so it would have already passed us.
We'd have to go FTL a loooong way to look for any signal.

I recall taking a high-bay tour when I hired into Lockheed, and saw it in mostly-assembled form in 1985. Then I worked the program while waiting for a clearance. Which part of it did you build?
This is a problem with Nasa today.
Anybody but Bush. That means Kerry. Not Nader.
Yea, cause slashdot never makes mistakes. Kettle -> Pot -> Black.
:-D
Oh, and by the way, it doesn't point at different stars. Clean your monitor.
Venus can cast shadows and it is pretty bright but it doesn't make it as it were day. Neither full mooon, which is the brightest object in the sky by far but it makes the terrain visible pretty easily.
If they weren't native, then probably they had the means of travelling between star systems, no contest, it's just like a huge Florida evacuation, only 14 million times larger. :-)
Has it reached it's peak brilliance yet?
"its".
You do realize they touch up the hubble pictures with colors and highlights, right?
Otherwise, they'd all be uninteresting and NASA would lose research money.
so just a question,
how hard would it be to actually replace hubble with a similar yet much more modern instrument? And just how long would it take. Lets say we kept with the hubble design and just upgraded everything. Can you put a new hubble into orbit without a shuttle launch and if so, why not do that. It can't be that expensive to build a clone and this time they know what to generally expect. I'm no genius on this stuff but I was wondering if anyone had any reliable information on the prospects of saving hubble this way.
I would think having done it once, it could be done again faster and cheaper and with less things going wrong.
but why is a story about a momentous event in the Universe associated with a 2-bit pirate site. Supernovas gave us Oxygen not a screeners version of Spiderman 2.
OMFG this l33t !!1111!1!!11oneeleven!!1! shit has got to stop. For all that his holy on slashdot plz quit the n00b1sh 11oneone crap or I'll have to start hunting each and every one of you down and 0wn j00 with my evil-bit encapsulated ICMP packet canon.

Everything would be just peachy with the submitter.
Looks like they goofed in one of the images, though--the arrow points to a different bright spot on the before-and-after image than it does on the main and annotated images.
Look better. The two last images point to the same place. See the "small" galaxy or whatever at the bottom of the pointed supernova on the two last photos pointed on the quote. They're the same as the big one pointed on the first one, the photo has only been zoomed to that area.
Your head a splode
... how rare this is. The last real supernova was in the constellation Monoceros in the 1980s, and it was the first one since the invention of the telescope. That makes this the second.
found a lot of bittorrent files ....
"its".
"Fucking Nazi."
There was an interesting article on spacedaily.com (The case against Hubble) which proposes that 2 new cheaper modern telescopes could be built for the price of "repairing" hubble.. I was in favour, until I heard about the costs.. Its had a damn good run, and will continue to do good science, but its like an old car that is costing more and more to put through its MOT each year..
"You lied to me! There is a Swansea!"
... what distance is safe from a supernova? I mean, in lightyears, for instance...
Thanks in advance.
An "up close and personal" supernova might have been responsible for the Cambrian-Ordovician mass extinctions and glacial age, some 0.5 billion of years ago. The massive pulse of gamma ray turned the ozone layer into a brown nitrous dioxide layer.

In turn that (A) allowed UV radiation from the sun to cook a lot of organisms. Yes, including those under water. _And_ (B) affected the climate so massively, that the Earth was turned into a cosmic ball of ice for an awfully long time. _And_ (C) must have caused one hell of a nitrous acid rain.
So I'd say you _really_ don't want to see one up close and personal.

Saeed's smarmy dig about this week's ISS EVA and the risk of a Hubble mission is wrongheaded. A Hubble repair mission is riskier than an ISS mission precisely because the crew can't shelter in the ISS if damage to the Shuttle precludes its safe reentry. EVA wasn't part of that decision.
-- Slashdot: When Public Access TV Says "No"
Since you obviously aren't acquainted with astronomy, allow me to explain. In order to orient yourself when looking at the sky, and since the picture may not have the same relative position that you do when looking at it, direction indicators are given so that you can recognize where to look when independently looking.
By convention star charts are made so that when you hold them up against the sky they orient to north,south, etc. This means that if north is up on the chart East is on the left. Since photographs are not neccessarily orthographic to this artificial reference frame, North-West pointers are used so they can be simultaneously compared to the observable sky or charts.
OK, pay attention people. The ISS spacewalk presents very little risk of a dead (astro|cosmo)naut - at worst the guy turns around and goes back into the ISS.
A shuttle mission to the ISS has a fallback position if the shuttle is found to not be re-entry worthy - park at the ISS and wait for a rescue mission.
A mission to Hubble has no such fallback - there is no way a shuttle in an orbit suitable to rendevous with Hubble can rendevous with the ISS. Should the shuttle not be re-entry worthy there is no fallback position - no ISS, no LEM, no option. You have several astronauts on orbit who are going to die. Slowly. Publicly.
Yes, Hubble is important to science. Is it important enough to sacrifice three to five astronauts?

No, but it is easily visible in an 8" telescope.

You misspelled "Fascist"... did you flunk English or something?
Do you think there's no reason to improve just because you aren't in class any longer?
When supernova 1987A went off, the KAMIOKA detector in japan detected a burst (I think it was ~10) neutrinos. With new detectors online to detect different neutrino flavors, it will be interesting to see if there's any new physics to be found.
It's not wasting time, I'm educating myself.
Still don't understand the bitterness regarding humans not being allowed to service Hubble. NASA already agreed to defer its Mars plan to send a robot to Hubble. Most of the world's population thinks human life is more valuable than a telescope. For all the bitching and whining the software engineering community did about astronauts dying on space shuttles, turning around and now saying humans should go out to Hubble shows absolutely no spine at all.
Does anyone in our industry still have an opinion or is it just about disagreeing with everyone else, no matter what their opinion is.
Yarr, my bad. Got a very polite email to that effect also. I looked at the images for a while but didn't see the smaller cloud in the larger image that is the only cloud in the smaller one.
Bah, details...
