What’s a Higgs Boson, Anyway?

With the science world all abuzz in anticipation of tomorrow’s official announcement from CERN in regards to its hunt for the Higgs, some of you may be wondering, “what’s a Higgs?” And for that matter, what’s a boson?

The video above, released a couple of months ago by the talented Jorge Cham at PHDcomics, gives a entertaining run-down of subatomic particles, how they interact and how, if it exists — which, by now, many are sure it does — the Higgs relates to them.

It’s the 7-minutes course in particle physics you’ll wish you had taken in college (unless you’re a particle physicist in which case… well, you’d still probably have enjoyed it.)

For over 50 years, award-winning space and astronomy artist David A. Hardy has taken us to places we could only dream of visiting. His career started before the first planetary probes blasted off from Earth to travel to destinations in our solar system and before space telescopes viewed distant places in our Universe. It is striking to view his early work and to see how accurately he depicted distant vistas and landscapes, and surely, his paintings of orbiting space stations and bases on the Moon and Mars have inspired generations of hopeful space travelers.

Hardy published his first work in 1952 when he was just 15. He has since illustrated and produced covers for dozens of science and science fiction books and magazines. He has written and illustrated his own books and has worked with astronomy and space legends like Patrick Moore, Arthur C. Clarke, Carl Sagan, Wernher von Braun, and Isaac Asimov. His work has been exhibited around the world, including at the National Air & Space Museum in Washington, D.C. which houses two of his paintings.

Universe Today is proud to announce that Hardy has helped us update the banner at the top of our website (originally designed by Christopher Sisk) to make it more astronomically accurate.

Hardy has also recently debuted his own new website where visitors can peruse and learn more about his work, and buy prints and other items.

We had the chance to talk with Hardy about his enduring space art and career:

'Skiing on Europa' by David A. Hardy, 1981. Used by permission.

Universe Today: When you first started your space art, there weren’t images from Voyager, Cassini, Hubble, etc. to give you ideas for planetary surfaces and colored space views. What was your inspiration?

David Hardy: I got to look through a telescope when I was about 16. You only have to see the long shadows creeping across a lunar crater to know that this is a world. But I also found the book ‘The Conquest of Space‘ in my local library, and Chesley Bonestell’s photographic paintings of the Moon and planets just blew me away! I knew that I wanted to produce pictures that would show people what it’s really like out there — not just as rather blurry discs of light through a telescope.

UT: And now that we have such spacecraft sending back amazing images, how has that changed your art, or how have the space images inspired you?

Hardy: I was lucky to start when I did, because in 1957 we had Sputnik, and then the exploration of space really started. We started getting photos of the Earth from space, and of the Moon from probes and orbiters, then of Mars, and eventually from the outer planets. Each of these made it possible to produce better and more realistic and accurate paintings of these worlds.

'Ferry Rocket and Space Station' by David A. Hardy. Used by permission. Hardy’s description: ‘A wheel-shaped space station as designed by Wernher von Braun, and a dumbbell-shaped deep-space vehicle designed by Arthur C. Clarke to travel out to Mars and beyond. The only photographs of the Earth from space at this time were a few black-and-white ones from captured German V-2s.’

UT: We are amazed at your early work — you were so young and doing such amazing space art! How does it feel to have inspired several generations of people? — Surely your art has driven many to say, “I want to go there!”

Hardy: I certainly hope so — that was the idea! In 1954 I met the astronomer Patrick Moore, who asked me to illustrate a new book in 1954, and we have continued to work together until the present day. Back then we wanted to so a sort of British version of The Conquest of Space, which we called ‘The Challenge of the Stars.’ In the 1950s we couldn’t find a publisher — they all said it was ‘too speculative!’ But a book with that title was published in 1972; ironically (and unbelievably), just when humans visited the Moon for the last time. We had hoped that the first Moon-landings would lead to a base, and that we would go on to Mars, but for all sorts of reasons (mainly political) this never happened. In 2004 Patrick and I produced a book called ‘Futures: 50 Years in Space,’ celebrating our 50 years together. It was subtitled: ‘The Challenge of the Stars: What we thought then –What we know now.’

I quite often find that younger space artists tell me they were influenced by The Challenge of the Stars, just as I was influenced by The Conquest of Space, and this is a great honour.

'Mars From Deimos' 1956. Credit: David A. Hardy. Used by permission. Hardy's description: 'The dumbell-shaped spaceship (designed by Arthur C. Clarke) shown in the previous 'space station' image has arrived, touching down lightly in the low gravity of Mars's little outer moon, Deimos. The polar cap is clearly visible, and at that time it was still considered possible that the dark areas on Mars were caused by vegetation, fed by the melting caps. On the right of the planet is Phobos, the inner moon.'

UT: What places on Earth have most inspired your art?

Hardy: I’m a past President (and now European VP) of the International Association of Astronomical Artists (IAAA; www.iaaa.org), and we hold workshops in the most ‘alien’ parts of Planet Earth. Through these I have been to the volcanoes of Hawaii and Iceland, to Death Valley CA, the Grand Canyon and Meteor Crater, AZ, to Nicaragua. . . all of these provide not just inspiration but analogues of other worlds like Mars, Io or Triton, so that we can make our work more believable and authentic — as well as more beautiful, hopefully.

UT: How has technology changed how you do your work?

Hardy: I have always kept up with new technology, making use of xeroxes, photography (I used to do all my own darkroom work and processing), and most recently computers. I got an Atari ST with 512k (yes, K!) of RAM in 1986, and my first Mac in 1991. I use Photoshop daily, but I use hardly any 3D techniques, apart from Terragen to produce basic landscapes and Poser for figures. I do feel that 3D digital techniques can make art more impersonal; it can be difficult or impossible to know who created it! And I still enjoy painting in acrylics, especially large works on which I can use ‘impasto’ –laying on paint thickly with a palette knife and introducing textures that cannot be produced digitally!

'Antares 2' by David A. Hardy, shows a landscape looking up at the red supergiant star, which we see in Scorpio and is one of the biggest and brightest stars known. It has a small bluish companion, Antares B.

UT: Your new website is a joy to peruse — how does technology/the internet help you to share your work?

Hardy: Thank you. It is hard now to remember how we used to work when we were limited to sending work by mail, or faxing sketches and so on. The ability to send first a low-res jpeg for approval, and then a high-res one to appear in a book or on a magazine cover, is one of the main advantages, and indeed great joys, of this new technology.

UT: I imagine an artist as a person working alone. However, you are part of a group of artists and are involved heavily in the Association of Science Fiction and Fantasy Artists. How helpful is it to have associations with fellow artists?

Hardy: It is true that until 1988, when I met other IAAA artists (both US, Canadian and, then, Soviet, including cosmonaut Alexei Leonov) in Iceland I had considered myself something of a lone wolf. So it was almost like ‘coming out of the closet’ to meet other artists who were on the same wavelength, and could exchange notes, hints and tips.

'Ice Moon' by David Hardy. Used by permission.

UT: Do you have a favorite image that you’ve created?

Hardy: Usually the last! Which in this case is a commission for a metre-wide painting on canvas called ‘Ice Moon’. I put this on Facebook, where it has received around 100 comments and ‘likes’ — all favourable, I’m glad to say. It can be seen there on my page, or on my own website, www.astroart.org (UT note: this is a painting in acrylics on stretched canvas, with the description,”A blue ice moon of a gas giant, with a derelict spaceship which shouldn’t look like a spaceship at first glance.”)

UT: Anything else you feel is important for people to know about your work?

Hardy: I do feel that it’s quite important for people to understand the difference between astronomical or space art, and SF (‘sci-fi’) or fantasy art. The latter can use a lot more imagination, but often contains very little science — and often gets it quite wrong. I also produce a lot of SF work, which can be seen on my site, and have done around 70 covers for ‘The Magazine of Fantasy & Science Fiction’ since 1971, and many for ‘Analog’. I’m Vice President of the Association of Science Fiction & Fantasy Artists (ASFA; www.asfa-art.org ) too. But I always make sure that my science is right! I would also like to see space art more widely accepted in art galleries, and in the Art world in general; we do tend to feel marginalised.

UT: Thank you for providing Universe Today with a more “accurate” banner — we really appreciate your contribution to our site!

Hardy: My pleasure.

Planetary Bake Sale and Car Wash to Support Exploration of the Solar System

Would you support a car wash or bake sale for planetary science?

[/caption]

Across the country, planetary scientists and students are planning for an upcoming bake sale and car wash on June 9, 2012. The event is in response to the 21% proposed budget cuts to planetary exploration, and while the volunteer bakers and washers will take donations, the main idea is to get the word out to the general public about the proposed budget slashing, and to ask people to send letters to their representatives. “Take Social Action and Participate,” says the event website. “Help Protect the NASA Planetary Budget from Cuts!”

The event was organized by Alan Stern, Principal Investigator of the New Horizons mission and former Associate Administrator of NASA’s Science Mission Directorate. There are several institutions across the US who already have events planned, (see here for planned events) and Stern is hoping for more events to be added. There’s even a ‘cookbook’ of ideas and instructions for how to host an event.

The event is supported by the Division for Planetary Sciences (DPS) of the American Astronomical Society, the world’s largest professional association of planetary scientists, which urges Congress to support and fund a vigorous planetary science program as recommended by the National Research Council. “We strongly believe that the robotic exploration of the solar system resonates with the American people; it is something that NASA needs to be doing and doing exceptionally well, and it is something the American people will support even in tight budget times,” the DPS said in a statement.

At the Lunar and Planetary Science Conference in March, Steve Squyres, Principal Investigator of the Mars Exploration Rovers and chair of the recent National Research Council (NRC) Decadal Survey for planetary science, said that for the planetary science budget to be restored, it would be crucial for the scientific community to respond in a unified fashion. “I’ve spent a lot of time looking at the budget, and as bad as it looks, they are looking for reasons to cut even further. There just is not enough money. What we just cannot do, we can’t give anyone reasons to cut even further. There are people looking to do that. We must respond as a unified voice.”

This bake sale and carwash is an attempt to have a unified voice across the country of showing how devastating the cuts would be for the future of NASA’s overall vision. President Obama has stated he will see astronauts on Mars in his lifetime, so the plan to put the Mars program essentially on hold is perplexing.

Additionally, the job losses and “institutional knowledge” losses would be devastating. “A 20% budget cut will likely equal 20% loss of jobs,” one commenter from the audience at the LPSC NASA Night event said. “People who land missions on Mars will lose their jobs, and when we get to the stage of landing humans on Mars, those with the know-how won’t be there.”

Why Are Astronauts Weightless in Space?

Most of our regular readers understand why astronauts and objects appear to float around on the International Space Station, but there are some misconceptions and preconceived notions out there on this topic that aren’t true and which don’t represent a very good understanding of physics! This video provides an entertaining look at some of the ideas people have about the zero-gravity environment on board an orbiting spacecraft, and shows why the astronauts actually appear weightless.

But let’s discuss it, too:

See Soundwaves in Space

What fun! The science officer aboard the International Space Station, Don Pettit, does some simple but amazing science in his series, Science Off the Sphere. In his latest video, Pettit allows us to ‘see’ sound waves in space.

“I’m amazed at how much fun you can with something as simple as a set of speakers from your laptop computer and a splash of water,” said Pettit who added that he wanted to see how sound waves would affect water droplets “without the complications of gravity.”

Make sure you watch to the very end to rock out with Pettit and see the variations between the woofer and tweeter on the speaker and how the different sounds affect the water drops.

We Really Hope ET is Out There, But There’s Not Enough Scientific Evidence, Researchers Say

For many of us who grew up listening to Carl Sagan, watching robotic spacecraft travel to other worlds, and indulging in science fiction books and movies, it’s a given: one day we’ll find life somewhere else in the solar system or Universe. But are we being too optimistic? Two researchers say that our hopes and expectations of finding ET might be based more on optimism than scientific evidence, and the recent discoveries of exoplanets that might be similar to Earth are probably getting everyone’s hopes up too high.

Astrophysicist Edwin Turner from Princeton and researcher David Spiegel from the Institute for Advanced Study say the idea that life has or could arise in an another Earth-like environment has only a small amount of supporting evidence, most of it extrapolated from what is known about abiogenesis, or the emergence of life, on early Earth. Their research says the expectations of life cropping up on exoplanets are largely based on the assumption that it would or will happen if the same conditions as Earth exist elsewhere.

Using a Bayesian analysis — which weighs how much of a scientific conclusion stems from actual data and how much comes from the prior assumptions of the scientist — the duo concluded that current knowledge about life on other planets suggests Earth might be a cosmic aberration, where life took shape unusually fast and furious. If so, then the chances of the average terrestrial planet hosting life would be low.

“Fossil evidence suggests that life began very early in Earth’s history and that has led people to determine that life might be quite common in the universe because it happened so quickly here, but the knowledge about life on Earth simply doesn’t reveal much about the actual probability of life on other planets,” Turner said.

So, if a scientist starts out assuming that the chances of life existing on another planet is as large as on Earth, then their scientific results will be presented in a way that supports that likelihood, Turner said.

“Information about that probability comes largely from the assumptions scientists have going in, and some of the most optimistic conclusions have been based almost entirely on those assumptions,” he said.

Therefore, with all the exoplanets being found, and as our discoveries have become more and more enticingly Earth-like, these planets have our knowledge of life on Earth projected onto them, the researchers said.

How does an exoplanet researcher feel about this? Turner and Spiegel found a sympathetic soul in Joshua Winn from the Massachusetts Institute of Technology, who said that the two cast convincing doubt on a prominent basis for expecting extraterrestrial life.

“There is a commonly heard argument that life must be common or else it would not have arisen so quickly after the surface of the Earth cooled,” Winn said. “This argument seems persuasive on its face, but Spiegel and Turner have shown it doesn’t stand up to a rigorous statistical examination — with a sample of only one life-bearing planet, one cannot even get a ballpark estimate of the abundance of life in the universe.

It is true that science is about facts — not about what your gut feelings are. But there’s a strong argument that we need inspiration to do the best, most engaging science. Writer Andrew Zimmerman Jones blogged today at PBS about how many scientists were spurred to follow their careers by reading science fiction when they were young.

“The finest science fiction is inspired by the same thing that has inspired the greatest science discoveries throughout the ages: optimism for the future,” wrote Jones.

And perhaps that is what is mostly behind our hopes for finding ET: optimism for the future of the human race, that we really could one day travel to other worlds, and find new friends — “to explore strange new worlds, to seek out new life and new civilizations, to boldly go where no one has gone before…”

Turner and Spiegel do say they are not making judgments, but just analyzing existing data that suggests the debate about the existence of life on other planets is framed largely by the prior assumptions of the participants.

“It could easily be that life came about on Earth one way, but came about on other planets in other ways, if it came about at all,” Turner said. “The best way to find out, of course, is to look. But I don’t think we’ll know by debating the process of how life came about on Earth.”
