ET Amazon Device Deals: Amazon Echo Show 8 for $69, Ring Video Doorbell 3 w/ Echo Show 5 for $149

Amazon is once again running sales on many of its own products with prices that match what we saw during Prime Day. In addition to Amazon’s Echo Show and Fire TV devices, you can also save on Amazon’s Kindle and some Ring Video Doorbell home security cameras.

Amazon Echo Show 8 ($69.99)

Amazon’s Echo Show 8 features an 8-inch HD display and is compatible with a wide range of Amazon- and Alexa-enabled services. It can work as a display for home security devices like Ring’s video doorbell, and it can be used for calling people and numerous other functions. I personally like to use mine for watching YouTube videos before bed and for listening to music. The Echo Show 8 typically costs $164.98, but you buy it now from Amazon marked down to $69.99.

Ring Video Doorbell 3 w/ Echo Show 5 ($149.99)

Ring’s new Video Doorbell 3 features a 1080p HD video camera and it has built-in speakers and a microphone. Compared with the older Video Doorbell 2, this device has upgraded motion detection, and it also comes with an Amazon Echo Show 5. The Echo Show 5 is a useful addition to have with the Doorbell 3 as it can be used to display footage from the Doorbell 3’s camera and it can also be used to talk to whoever is at the door. You can get it now from Amazon marked down from $289.98 to $149.99.

Amazon Fire TV Stick Lite ($17.99)

Amazon’s new Fire TV Stick Lite is essentially the same as the company’s regular Fire TV Stick. The key difference is that this model comes with a less advanced remote and can’t control your TV. This is a minor inconvenience, but if you’re looking for a cheaper alternative to the Fire TV Stick then you just found it. Amazon set this device with an MSRP of $29.99, but you can get it now for a limited time for just $17.99.

Amazon Kindle — Newest Edition w/ Built-in Front Light + 3-Month Kindle Unlimited Subscription ($59.99)

Amazon’s newest Kindle comes with a built-in front light, a high-quality 167ppi display, and a battery that can last for weeks without needing to be recharged. For a limited time, you can get this Kindle along with a three-month subscription to Kindle Unlimited marked down from $89.99 to just $59.99. It should be noted, however, that this version is ad supported and it will have a few ads.

NASA Discovers Vital Organic Molecule on Titan

Titan might be just one of dozens of Saturnian moons, but it’s one of the most fascinating objects in the solar system regardless. Astronomers often refer to Titan as a planet-like moon — it’s larger than Mercury and has a thick atmosphere like Earth and Venus. The environment is not hospitable to human life, but scientists have still found numerous intriguing organic compounds. In the latest analysis, researchers from NASA have identified an important, highly reactive organic molecule in Titan’s atmosphere. Its presence suggests the moon could support chemical processes that we usually associate with life.

A thick organonitrogen haze obscures the surface of Titan, but scientists were shocked to see how varied and planet-like it was under all the clouds. Titan is the only object in the solar system aside from Earth that has permanent bodies of liquid on the surface. On Earth, the liquid is water, but the seas on Titan are composed of liquid hydrocarbons. However, just because humans wouldn’t be at home on Titan doesn’t mean the moon is completely uninhabitable.

The NASA team used the Atacama Large Millimeter/submillimeter Array (ALMA) to probe Titan’s murky atmosphere to better understand its complex chemical composition, and the researchers spotted a molecule known as cyclopropenylidene (C3H2). The team says this discovery has the potential to open up new arms of chemistry on Titan, many of them associated with life. Cyclopropenylidene is what’s known as a cyclic or “closed-loop” molecule similar to benzene, and for the record, scientists have known benzene exists on Titan since 2003. Cyclic molecules are a vital piece of organic chemistry and might even be precursors to life.

Titan isn’t the only place we’ve found cyclopropenylidene — it’s also a common constituent of molecular clouds drifting through space. However, this is the first time it’s been detected in an atmosphere. The molecules floating in space are too cold and far apart to facilitate chemical reactions, but on Titan, cyclopropenylidene could form molecules very much like the nucleobases of DNA.

The more we learn about Titan, the more fascinating its chemistry becomes. We may be looking at a mixture of molecules not unlike those that gave rise to life on Earth. Unfortunately, it’s hard to study Titan from so far away. NASA hopes to launch a mission to Titan in the late 2020s that can explore these questions in detail. The Dragonfly lander should arrive on Titan in 2034, based on current projections. This drone will fly between multiple sites on the surface, using its instruments to probe the moon for compounds of scientific interest.
