Success! Engineers Cheer as Particles Blast Around LHC

Protons are currently being accelerated close to the speed of light in the LHC (CERN) — The new European proton superhighway (CERN)

The biggest experiment ever conceived by mankind was powered up today (Wednesday morning, GMT) and successfully circulated the first beam of protons. This is the first step toward LHC particles attaining relativistic velocities, completing 11,000 laps of the 27 km (17 mile) Large Hadron Collider (LHC) per second. This incredible feat of accelerator engineering is unparalleled, eventually allowing two counter-rotating beams of particles to be focused and collided within scales previously unimaginable. It is hoped the LHC will accelerate particles to such high energies that 14 TeV collisions will be possible by 2010, possibly revealing undiscovered particles, including the much sought-after Higgs Boson.

Although today is a hugely significant time for science (and a historic one for mankind), the first collisions will take place in October; today is a “dry run,” allowing the protons to circulate one-way. According to sources, today’s protons were accelerated around the instrument without issue, prompting LHC engineers to cheer when it was confirmed everything was on track…

Astroengine is Now Bulletproof: Upgrade to WordPress 2.6.2

WordPress released a minor upgrade today for any blog running version 2.6. Although it’s not a huge deal, it is worth doing if your WordPress installation allows open registration. Although this isn’t necessarily a security risk, there is the possibility that a hacker could exploit a WordPress function to reset admin passwords to a randomly generated one, therefore freezing the administrator out of their website. The hacker doesn’t know the new password either, so this loophole is more of a frustration than anything else. Still, it would be a bugger if that happened, so Astroengine is now bulletproof with v2.6.2…

Once again, I used the automatic upgrade plugin created by Keith Dsouza and it performed flawlessly, backing everything up and then installing the whole lot over the top. Superb.

Carnival of Space Week 69 – Free Space (Discovery)

This week’s Carnival of Space is being hosted by Irene Klotz over at the Discovery blog Free Space. There’s a great format this time, going from A-Z of all the submitted stories from across the space blogosphere, so be sure to check it out!

I was really slack this time and neglected to enter any of my Astroengine.com articles (*slaps wrist*), but I’ll be sure to get back on task in time for Week 70!

Listen to “10 Mysteries of the Solar System” With Captain Jack on Paranormal Radio

Paranormal Radio with Captain Jack logo

The recording of the September 1st Paranormal Radio show featuring Captain Jack and myself is now available for your listening pleasure. The show was entitled “Ten Mysteries of the Solar System” and it related to an article of the same name I wrote for the Universe Today on August 18th. It was great to be asked back to the show for the fourth time, and it looks like I might have a regular slot! As Jack said toward the end of the show, I am rapidly becoming PR’s resident “myth buster” – I am very honoured to have been given this task! Hopefully I’ll be appearing monthly to discuss the weird and wonderful goings on in our Universe, and Jack is a fantastic host, so we often go off on a tangent (as can be witnessed in this 3-hour show, I think it took me an hour just to talk about the first two mysteries of the ten!).

A Statement By Professor Brian Cox

Professor Brian Cox. Awesome. (Dave Pearson - http://tinyurl.com/62g84q) — Professor Brian Cox. Awesome. (Dave Pearson – http://tinyurl.com/62g84q)

On writing the article “Anyone Who Thinks the LHC Will Destroy the World is a Tw*t.” on Astroengine.com, I had no idea it would hit the front page of Digg.com and generate thousands of hits (booting Astroengine offline for 20 minutes). I wrote the supportive post as I believe Brian’s quote (from the Telegraph website), summed up the strain particle physicists are beginning to feel.

The original quote could be misconstrued as being offensive, but I believe the vast majority understood what he was saying. Brian was responding to reports that LHC scientists had received death threats in the run-up to the September 10th start date of the particle accelerator. With a combination of disinformation being spread by certain ill-informed individuals, media hype and mass hysteria, a solid statement was needed by a leading physicist to tame the unnecessary fear being whipped up.

I’ve been banging on about how safe the LHC is for some time, and I even vowed not to post another LHC doomsday debunking article as, quite frankly, I’m sick to death with the idiotic claims that micro-black holes, stranglets or gremlins could be produced by the LHC. The fact is that there is no danger and Brian explains why…

“Anyone Who Thinks the LHC Will Destroy the World is a Twat.”

Brian Cox giving an inspiring talk (TED)

I’m a huge fan of Brian Cox. He’s often referred to as the “rockstar of physics,” which is a big complement considering the stereotypical physicist in everyone’s mind. From the get-go you know that Professor Cox is a guy you want in your laboratory, and you can see why from this excellent TED lecture he gave in Monterey, CA, this year. He is a tireless advocate of communicating science to the world and his outreach style is second-to-none. But like many modern scientists who are working on cutting-edge research, they are often at the mercy of public misconception, media hype and personal attacks. So when I hear news that some Large Hadron Collider (LHC) physicists are receiving death threats, I lose my faith in humanity…

Last Look at GOCE Before Being Sealed Inside Rockot

The last look at GOCE before it is packed away inside the rocket two half-shells (ESA)

As you probably know, I am a huge fan of the Gravity field and steady-state Ocean Circulation Explorer (GOCE) as it is the sleekest, most aesthetically pleasing spacecraft I have ever seen. Rather than looking like a generic satellite, GOCE has been constructed in the shape of an aerodynamic spaceship as its orbit is so low that atmospheric drag will be a factor. Adding to the wow! factor is the GOCE ion engine giving a small but steady thrust to make sure GOCE doesn’t lose altitude during its Sun-synchronous orbit. Combine all these factors with the incredibly advanced science it will be carrying out during its 20 month lifetime, this is about as advanced as a terrestrial satellite can get.

So, ahead of its launch on September 10th, GOCE has been packed safely inside the Breeze-KM Upper Stage at the Plesetsk Cosmodrome in northern Russia. Next time the craft sees light will be three-minutes after launch in six days time…

Listen to the July 29th Discussion with Walter Wagner on Paranormal Radio

Paranormal Radio with Captain Jack logo

Over a month ago, I was asked to be a surprise guest over on Paranormal Radio with Captain Jack. And what was the discussion? Walter Wagner was on air discussing his “Doomsday Suit” against the US partners of the Large Hadron Collider at CERN and I had the great opportunity to put some questions to him. Critically for me, at about 99 minutes into the three-hour show (as I make my entrance), I ask Walter about his previous attempts at suing other particle accelerators (such as the Relativistic Heavy Ion Collider – RHIC – back in 1999). From that point on I believe the validity of the current LHC lawsuit seemed purely academic, but it certainly made for some great discussion.

Walter put across his views in a coherent and knowledgeable way and I made a point that scientists need to be challenged so the LHC can be fully justified (but I did also point out that filing a lawsuit might have pushed it a little too far). Although enjoyable, Walter didn’t convince me to change my views…

(Listen out for how many times I say “speculative”…)

CryoSat-2, a Satellite that Looks Like a Shed, Doing Science in the Freezer

Cryosat-2. Resembles something Da Vinci would design (ESA) — Cryosat-2. Resembles something Da Vinci would have designed (ESA)

ESA Cryosat-2 is set for launch in 2009 and it is the second attempt at getting the technology into orbit. Back in 2005, the original CryoSat was lost after a rocket malfunction caused it to fall short of the desired orbit, but much like the Phoenix Mars Lander story (i.e. it rose from the ashes of the lost Mars Polar Lander mission, recycled spare parts and reassembled the robot), Cryosat will fly once more. So what makes this mission so important? Well, it will carry out an essential three-year survey, measuring the thickness of global ice sheets.

But why am I really mentioning it? Like many ESA missions, the designs of their satellites and robots are so cool, and Cryosat-2 is no different. From some angles it looks like a sturdy intergalactic battleship, from others it looks like it was painstakingly designed by Da Vinci. Sometimes it even looks like a flying shed. In my books, that’s one interesting satellite. The science isn’t bad either…

A Strange Connection: Could Nuclear Decay Rates be Influenced by Distance From the Sun?

The decay rate of the radioactive isotope 32Si appears to correlate with orbital distance from the Sun (Jenkins et al. 2008)

Wouldn’t you think that the decay rates of isotopes found on Earth would remain fairly constant under controlled conditions? Statistically-speaking one would be able to make a pretty good prediction about a radioactive element’s decay rate at any point in the future, regardless of external influences. However, a group of researchers have found the radioisotope decay rates of radium (²²⁶Ra) and silicon (³²Si) varies periodically. This may not seem strange at first, but when measured, this fluctuation in decay rate has a period of approximately a year. Does this relate to the Earth’s position in its orbit? Does this mean radioactive decay rates are influenced depending on how far the element is from the Sun? Perhaps decay rates are not as predictable as we think…
