Hubble portrays a dusty spiral galaxy

ScienceDaily (Sep. 30, 2012) ? The NASA/ESA Hubble Space Telescope has provided another outstanding image of a nearby galaxy -- NGC 4183, seen with a beautiful backdrop of distant galaxies and nearby stars. Located about 55 million light-years from the sun and spanning about eighty thousand light-years, NGC 4183 is a little smaller than the Milky Way. This galaxy, which belongs to the Ursa Major Group, lies in the northern constellation of Canes Venatici (The Hunting Dogs).

NGC 4183 is a spiral galaxy with a faint core and an open spiral structure. Unfortunately, this galaxy is viewed edge-on from Earth, and we cannot fully appreciate its spiral arms. But we can admire its galactic disk.

The disks of galaxies are mainly composed of gas, dust and stars. There is evidence of dust over the galactic plane, visible as dark intricate filaments that block the visible light from the core of the galaxy. In addition, recent studies suggest that this galaxy may have a bar structure. Galactic bars are thought to act as a mechanism that channels gas from the spiral arms to the center, enhancing star formation, which is typically more pronounced in the spiral arms than in the bulge of the galaxy.

British astronomer William Herschel first observed NGC 4183 on 14 January 1778.

This picture was created from visible and infrared images taken with the Wide Field Channel of the Advanced Camera for Surveys. The field of view is approximately 3.4 arcminutes wide.

This image uses data identified by Luca Limatola in the Hubble's Hidden Treasures image processing competition.

Israelis are prepared ? and not ? for an Iran attack

Bernat Armangue / AP

An Israeli woman talks on the phone after collecting gas masks for her family in a shopping mall in Jerusalem in this Aug. 22 photo.

By Martin Fletcher, NBC News correspondent

TEL AVIV ? Did you know:

  • If a bomb explodes near you with a little bang, that's a sign it is carrying chemical or biological weapons? A loud bang means a conventional warhead.
  • If an attack is chemical, you will know right away? But if it's biological you'll only find out after a few days.
  • If it is nuclear, you should lie down and cover your head? And don't get up when the first blast wave passes over you because it will be followed by a second wave.

Useful, eh?

All these facts are good to know if you are in Israel and war with Iran, and its proxies Hezbollah and Hamas, were to break out around you.

Report: Iran mulls 'pre-emptive attack' against Israel; commander warns of 'World War III'

Or if something happened with Syria, Iran's ally, which has large stockpiles of biological and conventional weapons.

With the latest opinion polls showing that half of Israelis fear for the continued existence of their state if war breaks out with Iran, and with more than half rating the chance of such a war within a year as "medium" or "high,? the more you know about what the war would entail, the better.

In an attempt to convey what he sees as a threat to Israel's existence, Israel's Prime Minister Benjamin Netanyahu used a cartoon to illustrate how close he says Iran is to developing a nuclear weapon. In a speech at the United Nations General Assembly he asked the world to help stop them. NBC's Andrea Mitchell reports.

Here are some more facts:

  • If you suck a bead made of castor oil, it could kill you. It contains ricin, a lethal poison.
  • After Chernobyl, it took 25 years before Welsh sheep could be eaten because the nuclear radiation settled over Wales as it drifted most of the way round the world.
  • And cigarettes contain polonium 210, the poison used to murder the Soviet ex-spy Alexander Litvinenko.

Probably no country in the world is as prepared as Israel for such an attack, with every home built in the last 21 years possessing a mandatory bomb shelter. City centers have vast public shelters with special rooms set up for non-conventional attacks. And citizens are instructed in how to protect their bomb shelters against chemical and biological warfare.

Mistakes happen
But mistakes can happen, as I can personally attest.?

One evening in the winter of 1991 during the first Gulf War, with Iraqi Scud missiles rocketing over Jordan toward Israel, the bomb alarm sounded. My family quickly locked themselves in our bomb shelter, and I raced through the dark, silent streets to broadcast from our NBC News studio.

Israel's Netanyahu: Draw 'clear red line' to stop Iran from getting nuclear weapons

This had become routine. I spent all night in the studio, responding to the many alarms, and went home around 5a.m. I didn't check on the family because I knew where the Scuds had fallen and none were near my home.

This one time, however, with 30 minutes to go before my next live broadcast hit, I had a sense that something was wrong. For the first time after an attack, I called home to see how my wife and my three sons, all aged below six, were faring.

Israeli Prime Minister Benjamin Netanyahu tells the UN general assembly Thursday that sanctions are not stopping Iran's nuclear program.

No answer. I called again. No answer. Twenty-five minutes to go before my next ?live hit? on TV with Tom Brokaw. I felt sick with worry. What could have happened?

I ran downstairs, jumped into my car and raced home. I figured a 10-minute drive, five minutes at home and 10 minutes back, I'd be in the studio with seconds to spare.

Life-saving decision
Ends up, because of that calculation, I saved my family's lives.

When the all-clear sounded, my wife, our three sons, my sister-in-law and the dog, a schnauzer called Tofi, couldn't get out of the shelter.

The heavy steel lock would not budge. They hung on it and pulled and tried and tried but could not open the door. When I arrived home, about two hours after they had entered the bomb shelter, I heard faint cries of "help, help."

Instead of pushing the handle up, they had been pulling it down, locking it instead of opening it.

I was able to open the door from the outside and all was well.

But if I had stuck to my usual routine and not called home and just returned at 5 a.m., after leaving them at 8 p.m. the night before, they would have been dead.

It's simple math: An adult breathes about one cubic meter of air per hour, children more. Five people in a small room of about nine cubic meters would begin to lose air after two hours. Seven hours? They'd have all been dead.

A miracle? Sixth sense? Whatever, it's a warning of what can go wrong in times of stress. And however prepared Israelis are for what awaits them, accidents happen. When Iraq attacked Israel in 1991, far more people died of heart attacks than Scud rockets.

Country on edge
Since that time, every apartment built in Israel must have a blast-proof room that protects citizens from conventional blasts and also, with plastic and tape, can protect against chemical and biological weapons too. Walls and doors are approximately 8-12 inches thick and doors and windows are airtight.

Every citizen has, in theory, a gas mask. In practice, there aren't enough to go around.

Everybody asks, do you think there will be war with Iran? Nobody knows, and if you see Israel?s crowded cafes, the bustling streets, the crammed beaches, you may think that nobody cares.

Yet Israel is a country on edge. Most seem to have bought Prime Minister Benjamin Netanyahu?s line that the price to pay to stop Iran from building a nuclear bomb is much lower than the price to be paid if Iran has the bomb.

Fueling those thoughts are memories of what happened when the Nazis killed 6 million Jews. Today, there are approximately 6 million Jews in Israel. Few Israelis can argue against Netanyahu's insistence of: Never again.

And yet, I don't know anyone here who has prepared their bomb shelter. They're all a mess, used to store boxes, suitcases, footballs and wine. They are used as computer rooms, bicycle storage, play rooms. The attitude is, for the most part, we'll worry about it when the time comes.

Until then, live life.

SpaceX tests rocket engines for liftoff

SpaceX

SpaceX's Falcon 9 rocket fires its engines on a Cape Canaveral launch pad during Saturday's successful static fire test, in preparation for an Oct. 7 launch to the International Space Station.

By Alan Boyle

SpaceX says it successfully test-fired the engines on its Falcon 9 rocket today in preparation for Oct. 7's scheduled liftoff of the California-based company's first official cargo delivery to the International Space Station.

The static-fire test at Cape Canaveral Air Force Station in Florida was considered the "last major test" in advance of the launch, SpaceX said in a Twitter update. The rocket was held down while its nine Merlin engines blazed for a couple of seconds on the pad, at the end of a computer-controlled fueling sequence. Data from the test will be analyzed in advance of the scheduled launch at 8:34 p.m. ET on Oct. 7.


This will be the first launch under the terms of a 12-flight, $1.6 billion NASA contract to resupply the space station. In May, a SpaceX Falcon 9 rocket sent an unmanned Dragon capsule to its first space station hookup, during a NASA-funded demonstration flight. The success of that mission cleared the way for cargo flights to begin in earnest.

Another company, Orbital Sciences Corp., is working on its own launch system for supplying the space station: The first stage of Orbital's Antares rocket is due to roll out next week in preparation for a hold-down test on its Virginia launch pad.

SpaceX is also working on a modified version of the Dragon capsule that could be used to transfer NASA astronauts to and from the space station, beginning in the 2015-2017 time frame. That effort falls under a separate NASA program that is also funding spaceship development efforts by the Boeing Co. and Sierra Nevada Corp.

Watch this brief video of today's static-fire test:

Galaxy Note 2 release nears as multiple variants stroll through FCC (Verizon, AT&T and T-Mobile)


The Samsung Galaxy Note 2 has placed itself among the most anticipated devices of the year. This is despite its different, larger form-factor, which manufacturers tried to introduce before, but failed to do so right. Of course, the announcement invitations are enough proof that the device is coming to the US soon, but here is a bit more to get excited about ? FCC filings.

There are 3 versions of the ?phablet? strolling through the Federal Communications Commission, all headed to their relative major carrier ? AT&T, Verizon and T-Mobile. We have the SGH-i317 for AT&T, the SCH-i605 for Verizon and the SGH-T889 for Verizon. All come with LTE-compatible radios. Even the T-Mobile version, which hasn?t yet launched its upcoming LTE network (some good future-proofing).

There is a bit of bad news attached to this FCC filing, though. Samsung made it seem like they were finally improving their strategy with the faster and headache-less Galaxy S3 release, but it seems we are back to the older ways. All carriers have the same Galaxy S3 variant with identical specs (except radios), which was not the case with the Galaxy S and S2.

Yes, there seem to be completely different versions of the Galaxy Note 2 coming to the states. Internals should be relatively similar, but differences in aesthetics can bring many issues. For one, it creates major compatibility issues with accessories. One may also not be satisfied with the variant dedicated to one?s carrier, making us go through the hassle of switching carriers (or conforming with a ?lesser? variant).

Well, at least it looks like this release will be much speedier. This was our major grunt about multiple device variants ? it usually causes device releases to be delayed. Everything seems to be going smoothly this time, so let?s wait until October 24th for the official announcement and see what Sammy has for us.
