No Mistaking Astronomical Objects

“I’d rather be a could-be if I cannot be an are; because a could-be is a maybe who is reaching for a star. I’d rather be a has-been than a might-have-been, by far; for a might have-been has never been, but a has was once an are.” -Milton Berle Welcome to Messier Monday, where we pick…

“Men… have had the vanity to pretend that the world creation was made for them, whilst in reality the whole creation does not suspect their existence.” -Camille Flammarion Welcome to the latest — and most controversial – Messier Monday, where each week, I’ll take a look at one of the 110 deep-sky objects that make up…

“This nebula had such a resemblance to a comet in its form and brightness that I endeavored to find others, so that astronomers would not confuse these same nebulae with comets just beginning to shine.” -Charles Messier Let’s take a journey back in time to when our known Universe was a lot smaller. The only…

On Starts With a Bang, Ethan Siegel makes headway on his tour of "110 spectacular deep-sky objects" first cataloged by Charles Messier in 1758. Before powerful telescopes were developed, the heavens consisted of the sun, moon, stars, a few bright planets, and the rare passing comet. Comets were actively sought by men like Messier, who one night saw a bright smudge—too ill-defined to be a star—that "neither brightened nor changed position nor altered in appearance over the subsequent nights." He had spotted the beautiful Crab Nebula, an expanding lacework of stardust blown out by a supernova within our own galaxy. Unknown to Messier, some of his nebulae were entirely different galaxies, millions of light years distant, a structure scarcely conceived of in the 18th century (and not proven, on the basis of redshift, until 1912). Other Messier objects turn out to be spectacular star clusters, such as M13, which contains about 300,000 stars "from Sun-like ones down to red dwarfs and white dwarfs, a few blue stragglers (common to globulars), and a few red giant stars" within a diameter of 145 light years. But all these wonders of the universe looked about the same to Messier: things not to confuse with comets, ice orbiting the sun.

Last spring, the All England Squid Fishing Championships took place, in which hundreds of fishermen strove to catch the largest squid. Unfortunately, the weather was not conducive to good fishing, and they caught nothing. Well, except for one person who discovered this cute little guy cling to his jig. The winner! This gives me hope.…

If you havent heard, Richard Dawkins is cruising around Antarctica right now– Theyve upgraded internet abilities since I went, so he has been able to upload some Tweets and some photographs to flicker: I want to go back so goddamn badly, seeing these pics makes me sad.  Its like seeing an ex youre still in…

Check out this “sculpure” of a spider discovered by Biologist Phil Torres, created by what may be a new species of Cyclosa found in the Peruvian Amazon.

“Stuff your eyes with wonder, live as if you’d drop dead in ten seconds. See the world. It’s more fantastic than any dream made or paid for in factories.” -Ray Bradbury It wasn’t all that long ago — back when I was a boy — that the only planets we knew of were the ones in…

The wonderful Curiosity rover on Mars has been much in the news lately, but let’s not forget about the previous rover generation! Opportunity landed on Mars nine Earth calendar years ago today on 25 January, and it still works fine. Its mate Spirit was mobile on the Red Planet for over five years and then…

P points me at “Wikipedia knowledge: air-forger Connolley: The man who rewrote our worldview” and so on [cite. Not even original there; earlier at here]. I’m reading it via google translate, of course. Its mostly a re-hash of the Solomon nonsense which I discussed in A child’s garden of wikipedia, part I. Obviously, the bit…

Permaculture books telling you how to grow things abound.   They are many, varied and wonderful.  For some reason, however, permaculture books telling you how to EAT what you grow in interesting, creative and delicious ways are not, in fact, very abundant.   This is a pretty serious gap, given that in many cases, it…

Following on discussion arising from this post, here is a revised discussion of throwing in human evolution. The question of diversity in science, and more specifically, success for women, is often discussed in relation to bench or lab oriented fields. If you read the blogs that cover this sort of topic, they are very often…

The evidence from palaeoanthropology suggests that in the past humans were about the stature they are now, with more sexual dimporphism than now, with similar or larger brains than they have now, and used technology at the same level of sophistication as many later humans. Scientists argue over the degree to which modern day language…

I saw something odd in Marrakech recently. Along the main avenues there was a considerable amount of construction going on. But also properties right next door that had clearly been vacated years ago without receiving new buildings. And newish buildings and shop space that were boarded up. Freshly painted fronts of closed restaurants that looked…

As I hinted obliquely a little while back, I don’t have a terribly high opinion of Wall Street or Wall Street traders. Given that, I’m not the most obvious audience for a book titled The Physics of Wall Street, and truth be told, I wouldn’t’ve picked it up on my own. The publisher sent me…

It is an indisputable axiom that everything tastes better with bacon. Well, almost everything. As much as I love bacon, whenever I watch one of those cooking competition shows on the Food Network, like Iron Chef America, in which the secret ingredient is bacon, I can’t figure out how putting bacon in ice cream works.…

The Swedish Skeptics have announced their annual awards for 2012. Both the Enlightener award and the Deceiver award are given to the editorial staff of programmes on Swedish national radio. Medierna is a weekly media criticism show. They roast journalists in an excellently skeptical fashion and have during the year touched upon mistreatment of subjects…

If there’s one claim that practitioners of “holistic” medicine frequently make, it’s that “complementary and alternative medicine” (CAM) or “integrative medicine” or whatever the term du jour for the combining of quackery with science-based medicine is these days is allegedly so much better than “conventional” or “allopathic” medicine (or whatever disparaging term “holistic practitioners” prefer)…

Another list for your reading, gift-giving and collection development pleasure. Every year for the last bunch of years I’ve been linking to and posting about all the “year’s best sciencey books” lists that appear in various media outlets and shining a bit of light on the best of the year. All the previous 2012 lists…

Nothing like a little engineering humour to get the year off to a good start! This is one of my favourite engineer jokes, one that’s been kicking around the web for quite a while. I’m not sure the original source, but this is there I found it for today’s post. If you know the original…

Jobs

Workers in Travis County, Texas, are celebrating what advocates are calling a landmark victory, after local leaders voted to ensure that economic incentive deals benefit both big business and workers.

The collective experience of domestic workers — house cleaners, nannies and caregivers — often remains hidden from view. But a new survey has pulled back the curtain on the conditions and experiences domestic workers face, documenting issues such as wage exploitation, preventable on-the-job injuries and the little — if any — power domestic workers have in improving their work environments.

Exploring reliable links between work and depression, which is a significant health and economic burden for individuals as well as society, is somewhat murky. But a new study published in the American Journal of Public Health used two analytic strategies to address such criticism.
