The post National Science Week: Memes, blogs and videos: how social media has transformed the way we communicate science appeared first on Australian Science.
]]>Phil Plait – (AKA @BadAstronomer) an astronomer, writer and popular science blogger, Elise Andrew – Creator of I Fucking Love Science on Facebook; Henry Reich – Creator of MinutePhysics and MinuteEarth YouTube channels; Mitchell Moffit & Gregory Brown – Creators of AsapSCIENCE YouTube channel; Destin Sandlin – Creater of SmarterEveryDay YouTube channel; and Chris Cassella – Managing Director of Science Alert.
It really was a stellar ‘cast’ who have a combined social media reach of well over 100 million people per week. So what did these ‘giants’ of social media have to say about science communication? Well they said a lot, so I can only cover the highlights here. For a start – they all agreed – anyone can be a ‘science communicator’. You don’t have to be a scientist, or journalist or writer to be an effective science communicator, you just need to have a passion for science, and the time and ability to pass that information onto others. So what do the panel members think makes their science communication successful, and what can they suggest to someone interested in science communication?
Let’s start with Phil Plait, astronomer, author and science blogger who thinks that ‘all science is entertaining’! Phil selects topics for his blog based on what he’s excited by, not so much on what he thinks others want to see. Phil explained that his philosophy is that if he’s excited about it, other people will be excited about it. He recognises that people are often interested in the scary stuff, so he wrote ‘Death from the Skies’, where he talks about all the stuff that could kill us; blackholes, magnetic flares, supernovas, and killer asteroids. He recommends putting your own spin on a topic, if every one else is talking about it, you need differentiate yourself from everyone else.
In contrast to Phil, Elise Andrews, creator of the enormously popular I Fucking Love Science Facebook page, really didn’t start off with an idea of ‘doing’ social media. Elise manages a page with 6.4 million followers on her own, and admits that the task takes up all of her time. Elise’s tip is to use the Facebook scheduling function, which helps dramatically with maintaining content in a global 24 hour information cycle. She stressed that the viral nature of social media means that it’s one of the few ways we have to get the message of science and science communication in front of people who wouldn’t normally seek out science-related material. When asked about the contentious name of her page, Elise responded ‘the name of your page is important, you need a name you can’t not look at!’
Minute Physics creator Henry Reich has a background in physics, so that’s why he focuses on physics – he understands it and he wants others to understand it. Henry believes that traditional teaching of physics/science is classical and boring to most people, which is a shame, because right now current physics is focused on really cool stuff like the big bang, string theory, quantum theory, etc. When deciding on a topic Henry tries to focus on the cool stuff, he then tries to explain it in a way that is simple and fun – but remains true to the science. Minute Physics videos are restricted to a minute or two – that makes Henry focus on what is important and condenses the message – there’s no room for extraneous material or ‘fluff’, and that keeps the attention of the viewer.
AsapSCIENCE creators Mitchell and Gregory, who also have a YouTube channel agree that the traditional way of teaching science can be seen as boring and dry. They believe the message in traditional classroom learning is ‘goal focused’ rather than focusing on the details of the science. So when they pick a topic, they ask a question like ‘Why do we age?’ rather than starting with detailed descriptions of cell division and DNA replication, etc.. This makes the message more relatable, rather than what often happens in a classroom setting with it being very dry and overwhelming. Incorporating entertainment is a vital part of effectively communicating the message – it helps to overcome the reputation of science as being dry and boring, and overly serious.
The third member of the panel that has his own YouTube channel is Destin Sandlin, creator of Smarter Every Day. Although Destin has an engineering background – B.Sc. in Mechanical Engineering, M.Sc. in Aeronautical Engineering – he takes the approach that he’s just an average guy who is trying to figure something out that he doesn’t know. This allows him to take his viewers on a journey from unknowing to discovery to knowing. In crafting his videos he looks for the “Aha!” moment – the point at which you go from not-knowing to knowing how something works or what caused it to happen. Destin’s videos are progressive – each one starts off with simple concepts, gets progressively harder, until it spikes with a serious point, before it reaches its conclusion. He believes that each video needs to cater for all levels of viewer and should have something interesting for everyone.
Lastly, Science Alert Managing Director Chris Cassella, says that Science Alert started as a website promoting Australian science, since Australian scientific accomplishments are under-represented in the media and community awareness. Chris started to use Facebook to drive traffic to the website, although things didn’t quite work out that way. The Facebook page didn’t drive much traffic to the website, but there was fantastic engagement on Facebook – he then realised that Facebook itself was a better delivery medium. He recommends that sites mix up the serious science content with humorous memes, jokes, etc which breaks up the stream and helps keep people engaged.
During the Q&A session at the end of the panel, an audience member asked the panel for their advice to scientists on what they can do to help assist science popularisers to get the message out about new research. The immediate and very strong message from all panelists was, “publish your results in open access journals!” So often, they would love to link to new research, but linking to a paywalled paper or article creates a deluge of complaints from their audience – so they can’t do it.
So there’s a lot of information to take away from this group of committed science enthusiasts and communicators, but here’s a few tips:
– Be passionate about the science you love, whether it’s biology, physics, astronomy or chemistry – if you’re passionate about it, your enthusiasm will be passed on to your listeners/viewers.
– The advent of social media and platforms like Facebook, Twitter and YouTube means that you no longer need to have a lot of money or resources to be an effective science communicator, you can start with a laptop and internet connection and you’re on your way.
– You don’t need top notch equipment, ‘Hollywood’ style special effects or eye-wateringly expensive graphics to produce your own YouTube videos.
– Make sure you get your science facts right, but if you make a mistake, correct it, be transparent about it, and move on.

The post Postcard from Spitzer: weather on 2M2228 is hot and cloudy appeared first on Australian Science.
]]>Not that 2MASSJ22282889-431026 (or 2M2228 as it is known in The Astrophysical Journal Letters) will appear on a travel itinerary anytime soon. For 2M2228 is a brown dwarf, 39.1 light years from earth. Brown dwarves form out of condensing gas, as stars do, but lack the mass to fuse hydrogen atoms and produce energy. Instead, these objects, which some call failed stars, are more similar to gas planets, such as Jupiter and Saturn, with their complex, varied atmospheres. Although brown dwarves are cool relative to other stars, they are actually hot by earthly standards. This particular object is about 600 to 700 degrees Celsius.
The atmosphere of 2M2228
Astronomers using NASA’s Spitzer and Hubble space telescopes have probed the stormy atmosphere of this brown dwarf, creating the most detailed “weather map” yet for this class of cool, star-like orbs. “With Hubble and Spitzer, we were able to look at different atmospheric layers of a brown dwarf, similar to the way doctors use medical imaging techniques to study the different tissues in your body,” said Daniel Apai, the principal investigator of the research at the University of Arizona in Tucson.
But more surprising, the team also found the timing of this change in brightness depended on whether they looked using different wavelengths of infrared light.
These variations are the result of different layers or patches of material swirling around the brown dwarf in windy storms as large as Earth itself. Spitzer and Hubble see different atmospheric layers because certain infrared wavelengths are blocked by vapors of water and methane high up, while other infrared wavelengths emerge from much deeper layers.
The new research is a stepping-stone toward a better understanding not only of brown dwarves, but also of the atmospheres of planets beyond our solar system.
Into the red: the Spitzer space telescope
The Spitzer Space Telescope is the final mission in NASA’s Great Observatories Program – a family of four space-based observatories, each observing the Universe in a different kind of light. The other missions in the program include the visible-light Hubble Space Telescope, Compton Gamma-Ray Observatory, and the Chandra X-Ray Observatory.
The Spitzer Space Telescope consists of a 0.85-meter diameter telescope and three cryogenically-cooled science instruments which perform imaging and spectroscopy in the 3 – 180 micron wavelength range. Since infrared is primarily heat radiation, detectors are most sensitive to infrared light when they are kept extremely cold. Using the latest in large-format detector arrays, Spitzer is able to make observations that are more sensitive than any previous mission. Spitzer’s mission lifetime requirement was 2.5 years, then extended this to 5-years. Spitzer .
Launched on August 25, 2003 Spitzer is now more than 9 years into its mission, and orbits around the sun more than 100-million kilometers behind Earth. It has heated up just a bit – its instruments have warmed up from -271 Celsius to -242 Celsius. This is still way colder than a chunk of ice at 0 Celsius. More importantly, it is still cold enough for some of Spitzer’s infrared detectors to keep on probing the cosmos for at least two more years; the project funding has been extended to 2016.
Spitzer is the largest infrared telescope ever launched into space. Its highly sensitive instruments allow scientists to peer into cosmic regions that are hidden from optical telescopes, including dusty stellar nurseries, the centres of galaxies, and newly forming planetary systems. Spitzer’s infrared eyes also allows astronomers see cooler objects in space, like brown dwarves, extrasolar planets, giant molecular clouds, and organic molecules that may hold the secret to life on other planets.
Instead of orbiting Earth itself, the observatory trails behind Earth as it orbits the Sun and drifts away from us at about 1/10th of one astronomical unit per year.
This innovative orbit lets nature cool the telescope, allowing the observatory to operate for around 5.5 years using 360 litres of liquid helium coolant. In comparison, Spitzer’s predecessor, the Infrared Astronomical Satellite, used 520 litres of cryogen in only 10 months.
This unique orbital trajectory also keeps the observatory away from much of Earth’s heat, which can reach 250 Kelvin (-23 Celsius) for satellites and spacecraft in more conventional near-Earth orbits.
More scientific duets: the asteroid belt of Vega
Like a gracefully aging rock star Spitzer is reveling in duets. It has also teamed up with the European Space Agency‘s Herschel Space Observatory. Using data from both astronomers have discovered what appears to be a large asteroid belts around the star Vega, the second brightest star in northern night skies.
The data are consistent with the star having an inner, warm belt and outer, cool belt separated by a gap. The discovery of this asteroid belt-like band of debris around Vega makes the star similar to another observed star called Fomalhaut. Again this formation is similar to the asteroid and Kuiper belts in our own solar system.
What is maintaining the gap between the warm and cool belts around Vega and Fomalhaut? The results strongly suggest the answer is multiple planets. Our solar system’s asteroid belt, which lies between Mars and Jupiter, is maintained by the gravity of the terrestrial planets and the giant planets, and the outer Kuiper belt is sculpted by the giant planets.
“Our findings (accepted for publication in the Astrophysical Journal) echo recent results showing multiple-planet systems are common beyond our sun,” said Kate Su, an astronomer at the Steward Observatory at the University of Arizona, Tucson.
Vega and Fomalhaut are similar in other ways. Both are about twice the mass of our sun and burn a hotter, bluer color in visible light. Both stars are relatively nearby, at about 25 light-years away. Fomalhaut is thought to be around 400 million years old, but Vega could be closer to its 600 millionth birthday. For comparison our sun is 4,600 million years old. Fomalhaut has a single candidate planet orbiting it, Fomalhaut b, which orbits at the inner edge of its cometary belt.
The Herschel and Spitzer telescopes detected infrared light emitted by warm and cold dust in discrete bands around Vega and Fomalhaut, discovering the new asteroid belt around Vega and confirming the existence of the other belts around both stars. Comets and the collisions of rocky chunks replenish the dust in these bands. The inner belts in these systems cannot be seen in visible light because the glare of their stars outshines them.
It would seem that Spitzer has quite a bit more productive and novel scientific life, including duets, left in it yet.
