I’ve come to the hard decision that it’s time to put Steve Cross Loves Music and Science to rest. Don’t worry, I still love music and science! I just don’t have time to blog about it anymore. The natural progression of life, relationships, commitments, etc… has forced me to re-organize priorities. That’s not a bad thing, it just means that blogging has to take a backseat to more important things. So, this is the end of this blog! I’ll keep the domain for the foreseeable future, and everything will remain archived as-is. Everything has a a life cycle, and this blog has reached the end.
This is not the end of me sharing this type of content on the internet, however! I do intend to share more science articles, links, tidbits, etc… on my Facebook and Twitter feeds, so follow me there. This will allow me to still share my interests and love of music & science with whomever is willing to listen. I’m also on Instagram, so follow me there for more visual content.
I also have other blog ideas that I’ve been milling around for a while, but I’m keeping that under wraps until I officially decide what I’m doing. If and when that comes to fruition, it will be made public via my Twitter and Facebook.
Whether you’ve just started following me or have been for many years, I hope you learned something, gained something, or otherwise benefited from this blog!
It’s been quite a while since I posted much of anything weather-related, but now is as good a time as any! Our middle TN National Weather Service office started a Facebook page a while back, and I’ve been loving the hell out of it. Let’s face it, the weather service has always had a bit of an image problem. I’d be willing to bet that when most people think of the NWS, they think of a boring office with a bunch of crotchety old dudes staring at weather maps & computer screens. But in reality, the meteorologists are dedicated and passionate scientists who truly love what they do, and they enjoy talking about weather on a more conversational level, too! That’s exactly what their Facebook page is for, and it’s filled with tons of interesting factoids, tidbits, and more humanized/conversational information about the forecast. The forecasters are on there quite often, and are very good about responding to comments or questions posted. They also just closed submissions on a summer weather photo contest, and you can browse through the album and vote on your favorites. The photo with the most likes as of June 20th will be declared the winner. So check out their Facebook page and Like it. Even if you’re not as big of a weather nerd as I am, I promise you will learn something interesting if you Like the page and follow their posts!
Speaking of weather, I’m looking forward to the very favorable forecast for this year’s Bonnaroo! I will be there taking photos for the Scene as I have for the last 5 years, and thus I’m issuing my yearly Bonnaroo posting disclaimer: *This will be my last post before Bonnaroo, and posting will resume sometime early next week.* Be sure to follow our coverage and photos over at the Nashville Cream! Also, my girlfriend Lauren will be there with me blogging about the new & improved food options on her blog Old Red Boots, so follow her coverage to see the festival through the eyes of a foodie. But back to the weather- while it’d be nearly impossible to beat last year’s utterly euphoric Bonnaroo weather, this year’s forecast looks very good. Thursday is a little iffy as there’s currently a 30% chance of showers & storms, and the Storm Prediction Center has Manchester right on the edge of their ‘Slight Risk’ area for severe weather in their convective outlook. BUT, that activity should be pretty scattered/isolated so the risk is still pretty low. Friday & Saturday are damn-near perfect, however- sunny skies with mid to upper 80s for highs and low to mid 60s for lows- very similar to last year! That temperature span also suggests lower humidity! Sunday will be a little hotter with highs in the upper 80s and Sunday night brings back a 20% chance of showers. Overall, you really couldn’t ask for a better Bonnaroo weather forecast. See you here next week!
Here’s an interesting tidbit that came across my radar today: A very illusive and rare meteor shower may flare up tonight for the first time since 1930! On June 11th of that year, a small group of astronomers reported a short-lived meteor shower that was sought out in subsequent years, but never seen again. Now an astronomer named Peter Jenniskens with NASA and SETI has suggested that Earth is passing through the same comet trail it did back in 1930, and thus we could see this rare outburst, called the Gamma Delphinids, again- TONIGHT. Fortunately the moon will have set several hours before the expected peak between 2:30 and 4:30am CDT, leaving only the weather to stand in the way of getting to witness this rare event. I must point out, however, that scientists aren’t nearly as certain about this meteor shower as they are about the more reliable yearly showers such as the Leonids, Geminids, Perseids, etc… So if you’re a fan of meteor showers and have the will power to get up in the wee hours and sit outside to watch, tonight could reward your efforts with a show not seen in 83 years.

In other science news, more evidence of normal, habitable water on the ancient Mars surface was discovered recently. You’re probably thinking this discovery came from the Curiosity rover, but it actually came from Opportunity, one of the twin rovers that landed on Mars in 2004. Opportunity’s team sent her to investigate an interesting rock outcropping, and they found evidence of certain clay minerals that could only have formed in water that would be habitable to life as we know it. This discovery is right in line with Curiosity’s findings from February, and strongly supports the theory that Mars once had running water on the surface, and might have even supported microbial life! As Curiosity keeps trekking toward Mount Sharp, the rover will keep looking for these same minerals to help paint a clearer picture of Mars’ watery past. (Via New Scientist)
NASA’s Curiosity rover is back to work on Mars, after a few weeks of radio silence due to Mars’ being behind the Sun from Earth’s perspective. The photo above shows a new hole created by Curiosity’s drill, and scientists hope that the analysis of the samples taken from this hole will match up with, or at least support, the exciting results of the previous drilled rock analysis back in February. Those results suggested that Mars’ surface was once habitable for microbial life as we know it. The results of the analysis will no doubt be released in the next few weeks, before Curiosity begins the long drive to its ultimate destination, a huge layered mountain known as Mt. Sharp.

Warning: If you are one who is prone to getting sucked into rabbit holes of Wikipedia links and losing all sense of productivity, I highly recommend you DO NOT read this article while at work! Wikipedia has a really awesome, really addictive list of common misconceptions. Don’t say I didn’t warn you! (Via Kottke.org)
Some sad news from NASA: the immensely successful Kepler Mission in danger. The space-based planet hunting telescope has suffered another malfunction with one of its reaction wheels. The craft had four of these wheels to begin with, and they are responsible for keeping the spacecraft correctly oriented. It lost one of the wheels last year, but can still survive with three. Now that another wheel has stopped functioning, it will be nearly impossible for engineers to keep Kepler correctly pointed at the small patch of sky it’s been staring at since the mission began. NASA engineers think they can devise a way to use the spacecraft’s thrusters to coarsely aim it in the right direction, but since the process of analyzing Kepler’s observations is so painstaking and tedious, coarse alignments may not be accurate enough to keep the mission running normally. NASA engineers also haven’t given up on getting the wheel working again, so we’ll have to wait and see how this pans out. Even if Kepler dies, the mission has already been a huge success and there are several other new planet hunting missions in the works.

It’s been way too long since I last posted anything science-related. Photographing weddings, playing in two bands, and working a day job has eaten up all of my spare time lately! But I’ve found enough time to bring you some exciting updates and cool videos today.
Above is a comparison of the 5 newly confirmed exoplanets in the Kepler-62 system. The Kepler mission also confirmed an exoplanet around another star, Kepler-69, but that one isn’t nearly as interesting as the Kepler-62 system. Specifically, Kepler-62e and 62f are very exciting because they are officially the smallest potentially habitable exoplanets discovered to date! 62e and 62f are about 1.6 and 1.4 times the size of Earth, respectively. Based on our best computer models for planetary formation and evolution, scientists estimate that 62e is probably cloudy and quite warm, while 62f is probably covered in water and quite cooler, possibly even covered in ice. But different atmospheric conditions could change that significantly… there’s no way (yet) to know for sure. For more on this exciting discovery check out Universe Today and Bad Astronomy.
In related news: Building on the awesome success of the Kepler mission, NASA has announced its next exoplanet-hunting mission, the Transiting Exoplanet Survey Satellite, or TESS. Scheduled for launch in 2017, this new space-based telescope will look for exoplanets in the same way the Kepler mission has been, but it will use four wide-angle telescopes to look at a much broader part of the sky.
Now for the video goods. These are both very cool short segments from Canadian astronaut and current ISS commander Chris Hadfield.
This one is a mesmerizing demonstration of how water behaves in a zero-gravity environment by wringing out a wet washcloth:
And this one is Chris talking about possibly the coolest aspect of being in the ISS- taking breathtaking photographs of Earth from the ISS’s cupola:
Fuck yes! That’s all I can think right now about the awesome news that came from NASA a few hours ago. The Curiosity rover has found evidence in samples of rock gathered a few weeks ago that Mars once had an environment suitable for microbial life. The rover drilled out samples from inside a rock in an area dubbed “Yellowknife Bay” by mission scientists. Those powder samples where then analyzed by specialized instruments on board, and the results showed that sulfur, nitrogen, oxygen, hydrogen, phosphorus, and carbon are all present in the rock. The range of minerals actually surprised the mission scientists, who weren’t expecting to find quite such a wide range of minerals.
“Were conditions on Mars ever suitable for life?” is one of the core questions the Curiosity mission, and now that question has been answered with a big YES. This is very exciting news, and hopefully there will be even more clues into Mars’ past discovered on this mission. For the full report, check out the press release on NASA’s website.
In other, less-exciting science news, beware of media reports claiming that fossils of diatoms (microscopic plant life) were recently found inside a meteorite. The claims come from Chandra Wickramasinghe, who is a scientist known for outlandish claims that don’t stand up to real scientific scrutiny, and are largely intended to stir controversy. This latest report claims that the fossilized diatoms were found inside a fragment of a meteorite that fell over Sri Lanka in 2012. Except they don’t prove that a) the sample was from said meteorite, or b) that the sample was from a meteorite at all! Also diatoms are EVERYWHERE on earth, and can very quickly contaminate any meteorites that make it to the surface. Thankfully there are skeptics like Dr. Phil Plait out there who regularly and thoroughly debunk such things when they pop up. Head over to his blog Bad Astronomy to read more on how Wickramasinghe’s experiments were flawed, and why his claims just don’t hold water.
