If There’s an Alien Race Living on our Doorstep, Why Can’t We Hear Them?

As I was watching Battlestar Galactica last night, I was thinking about the lack of alien civilizations in the show. To be honest, I tire easily of humanoid alien beings with curiously shaped heads synonymous with Star Trek et al., so I’m loving the fact a far-off human colony created their own evil race, the Cylons. So far, so good, I’m getting sucked into BSG (will it be as good as, or even better than Bablyon 5? That has yet to be seen, but it looks promising).

These thoughts took me back to an Astroengine article I wrote in November with my usual gripe about our obsession for looking under rocks on Mars (The Search For Life, What’s the Point?). I reached the conclusion that I’d much rather be pottering around in an empty cosmos, devoid of life, than bumping into an angry neighbour who wants to probe/assimilate/hybridize me. Science fiction musings I know, but it isn’t that far from some of the conclusions that could arrive from using the famous Drake equation that underpins our incessant search for intelligent extraterrestrial life.

Today, I was referred to some research addressing the Fermi Paradox, although we haven’t heard from our extra-terrestrial neighbours yet, doesn’t mean they’re not transmitting. The galaxy could be teeming with intelligent aliens, but we just can’t hear them

When the Space Hotel’s a Rockin’…

Guest article by Greg Fish (blog: world of weird things)

You can’t go on vacation any more without your video camera, especially if you’re going some place spectacular and exciting. When the new wave of space tourists soars into orbit, they’re going to come back with some spectacular home movies. Some of them may be a lot steamier than others because there’s bound to be a couple just itching to be the first humans to have sex in space and capture it on high definition video to bolster their claim to fame. Yes, sex in space in inevitable and the moment people finally get a little privacy and a little room in which to play (something that’s missing on today’s space missions), it’s going to happen.

But before you rush to reinvent the Kama Sutra in 360 degree freedom, a few tips for you aspiring 60+ mile high club members…

2012 Fear = Money: Sony Pictures Cashes In

ihc

Another day, another inbox with three emails asking me about what this 2012 “thing” is all about.

Another two from concerned (but now relieved) readers and one (from late last night) calling me a fudging idiot (edit the italicized word). I had no idea that my 2012 articles on the Universe Today (and the growing number on Astroengine) would evoke such a spirited and sustained barrage of hate/love/relief mail. I’m a scientist, first and foremost, I’m not used to this kind of attention.

Seriously though, this 2012 insanity needs to calm down. Admittedly, telling “believers” there is nothing to fear about the Mayan calendar coming to the end (or the hopelessly flawed Bible Code is nonsense) is a bit like waving a red cloth in front of a pissed off bull, and any hope that we wont be barraged by doomsday hysteria in 2012 is a lost cause (in my opinion). But mainstream media really needs to lay off the scaremongering tactics.

I can deal with the crackpots, greedy authors, pseudo-science liars, misinformed and weak-minded “YouTube Scientists” spreading prophecies of doomsday, linking ancient prophecy (that has a non-existent prediction:proof ratio by the way) with modern science. But when Sony Pictures jump on the 2012 juggernaut, I think we can forget about having any sanity in the run-up to December 21st 2012.

Enter the Institute for Human Continuity, a Sony Pictures viral campaign…

Why Are Clandestine Space Launches So Sexy?

A Delta IV Heavy launches... but to where? (AFSC)
A Delta IV Heavy launches... but to where? (AFSC)

Last weekend (Saturday, Jan. 17th), one of the most powerful rockets on the planet thundered to life at Cape Canaveral Air Force Station, carrying something into space. Although the world has a good idea as to what this something was, it was a reminder that even during these times of intense media scrutiny and the guise of government transparency that there is a lot going on in space that we may never know about. However, far from clandestine launches at the dead of night being a bad thing, they appear to whet the worlds appetite for finding out more about the top secret military payloads routinely being put into orbit…

Is the Universe a Holographic Projection?

Could our cosmos be a projection from the edge of the observable Universe?

Sounds like a silly question, but scientists are seriously taking on this idea. As it happens, a gravitational wave detector in Germany is turning up null results on the gravitational wave detection front (no surprises there), but it may have discovered something even more fundamental than a ripple in space-time. The spurious noise being detected at the GEO600 experiment has foxed physicists for some time. However, a particle physicist from the accelerator facility Fermilab has stepped in with his suspicion that the GEO600 “noise” may not be just annoying static, it might be the quantum structure of space-time itself

Oh No! Rocket Launches Are Bad for the Environment? We’d Better Stay at Home Then

A small environmental impact, Falcon 1 launches in September 2008 (SpaceX)
A small environmental impact, Falcon 1 launches in September 2008 (SpaceX)

For every article written about the amazing advances in space vehicle technology, there are two negative comments about the pointlessness of space exploration.What’s the point?“, “We have war, famine, poverty and human suffering around the world, why invest billions on space?“, “What’s space exploration ever done for me?“. However, today, after I wrote a pretty innocuous article about the awesome SpaceX Falcon 9 rocket being hoisted vertically on the launchpad at Cape Canaveral, I get a comment (anonymous, naturally) starting off with, “This launch and others like it should be halted indefinitely until it’s carbon footprint and environmental impact can be accounted for.” The commenter then goes into something about making an environmental assessment, levying SpaceX’s taxes and setting up a board of environmental scientists. Oh please.

On the one hand, I’m impressed by this person’s spirited stand against environmental damage, carbon emissions and global warming, but on the other, this is probably one of the most misplaced environmentalism attacks I have seen to date. There are extremists on both sides of the “green” debate, but the last thing we need is an attack against the only answer we have to fight climate change. And that answer comes in the form of a cigar shaped polluter, blasting into Earth orbit; whether you like it or not, it is a necessary (yet small) evil…

Magnetars Born Through Quark Star Switch?

If you thought neutron stars and magnetars were exotic, think again. In studies of magnetars that occasionally blink to life, generating an intense blast of X-rays and gamma-rays, astronomers have been at a loss to explain why these objects have such strong magnetic fields. After all, after a supernova, a neutron star remnant conserves the angular momentum and magnetic field of the parent massive star; it is therefore a rapidly spinning, magnetically dominant entity, often observed emitting intense radiation from its poles (a.k.a. a pulsar).

However, magnetars (the most magnetically powerful objects observed in the Universe) do not have such a reasonable explanation for their magnetic field, it is simply too strong.

During the AAS conference last week, one scientist presented his research, possibly indicating another state of matter may be at play. A massive neutron star may pass through a “quark star phase”, kick starting a mechanism known as colour ferromagnetism

Small but Mighty: KPD 0005+5106, the 200,000K White Dwarf

Sirius B1 - one of the more famous white dwarf stars (Frank Gregorio)

A white dwarf called KPD 0005+5106 has been identified as the hottest star observed, ever. KPD 0005+5106 lives in the globular cluster M4, 7,200 light years away, and astronomers have always been intrigued by this stellar lightweight as its emissions have previously hinted it was quite toasty. Now, astronomers using data from the defunct NASA Far-Ultraviolet Spectroscopic Explorer (FUSE), have studied the white dwarf in more detail. KPD 0005+5106 emits radiation in the far-ultraviolet, indicating that its surface has a temperature of 200,000K. This is an unprecedented discovery, far-ultraviolet emissions are usually reserved for superheated stellar coronae. It may be small, but it’s a record-breaker

The Link Between Beer and the Colonization of Space

A Japanese brewery has successfully produced 100 litres of Space Beer. Hurrah!

The beer won’t actually be consumed in space (which seems a shame somehow), but it was made totally from barley grown on the International Space Station. For a lucky few, 60 people will get to sample the beer in Tokyo next month. So, what can they expect?

Alas, there won’t be much difference between the Sapporo Brewery’s 100% space barley brew when compared with a terrestrial grain as there is no measured difference in the DNA of barley grown in space when compared with barley grown on Earth. Therefore I doubt there will be any “eureka!” moment for the alcoholic beverage industry and therefore no immediate plans to launch a micro(gravity)brewery into orbit…

That said, this isn’t just a publicity stunt. The barley was grown as part of a joint Japanese/Russian experiment to test the suitability of certain crops to be grown in space. Along with the barley; wheat, peas and lettuce were also harvested. In previous tests, a Canadian research paper was presented revealing no difference between the DNA of barley grown in space when compared to the stuff grown on Earth. Although this kinda takes away from the possibility that space barley could make a better beer, it is reassuring to know that terrestrial foodstuffs can be grown in space with minimal risk of mutation (and possible hazardous side effects to space traveller’s health). Obviously more work will need to be done, with several generations of the same plant re-cultivated and harvested, but these first results are very exciting.

Hold on. Exciting? Why?

This is another step in the direction of a reduced dependence on Earth for the supply of food. If a Japanese brewery can produce 100 litres of beer from ingredients grown in space, we’ve made an important leap into the production of other consumables from ingredients grown in space. Imagine what this means for the future of mankind when we begin setting up colonies on the Moon and, eventually (in my lifetime I hope!) on Mars. The vision of cultivating food on other planets becomes one step closer to reality.

This is one of the International Space Station’s key strengths. It is a long-term scientific mission to assess man’s adaptability to a space-based environment. Growing barley in space is therefore not a commercial venture (Sapporo is not selling any of the Space Beer it produces, although the company will most certainly profit from some good exposure in the media), it is a critical step in our space-faring ability. Add this success to the recent installation of the urine recycling system added as part of the STS-126 shuttle mission to the ISS and you can see that we are beginning to cut the umbilical cord that prevents long-term manned space travel.

Hopefully, within 20 years, these techniques will have been perfected, allowing mankind to begin work on other planets, ultimately setting up self-sustaining colonies throughout the Solar System.

And all this excitement from the production of a small quantity of Space Beer…

The Cancer Spreads: Mars Science Laboratory Delayed Until 2011

The Mars Science Laboratory (MSL) project is failing. But it is not suffering from technical failure en-route to the Red Planet, it hasn’t gotten itself stuck in a Martian sand-trap, it hasn’t even fallen foul of the “Galactic Ghoul”; the MSL is suffering from an overlooked space exploration hazard: bad management. According to today’s (not unexpected) NASA announcement, the MSL will not be launched until 2011.

I had a very bad feeling about today’s press conference, and it looks like my fears were justified. Due to technical difficulties, the launch of the MSL is being delayed by two years, as the overrun will ensure the mission misses the next Mars launch window. So I have to ask: why is an over-budget, behind schedule, poorly managed mission being allowed to sap the budgets of other NASA programs when the solution is so obvious?
