Better Science Through Data Simulation

Today's #HubbleHangout  starts in 45 minutes! 

Join +Tony Darnell, Dr. +Carol Christian and me from the +Hubble Space Telescope as we discuss "Mocking the Universe," a recent workshop held at the +Space Telescope Science Institute with astronomers using astrophysical data to make computer simulations that better help us observe and understand the Universe.

We go live at 3pm Eastern/Noon Pacific.

How to Protect Yourself from "Stagefright"

Well, this is just horrifying. The Hangouts app is most vulnerable to this bug; you don't have to do anything but receive an MMS message to be exploited. The Messaging app is almost as bad: you have to view the message, but you'll be exploited even if you don't tap the attachment. Since you must generally view the message to determine whether it has an attachment, that level of resistance has limited value.

Google has already made security patches available to vendors and carriers, but the phone ecosystem being what it is, they won't arrive on your phone for a long time if ever. (I'm not sure why this can't be worked around with an update to the Hangouts and Messaging apps themselves, but I'm sure if it were that easy, they'd have done it already.) Meanwhile, protecting yourself from the bug -- code-named "Stagefright," after the Android library it exploits -- is up to you.

Now, I'm not pretending to be a phone security expert. And I'm not speaking for Google here. (I don't get paid anywhere near enough to do that job, thank you.) But I learned that the app TextSecure isn't vulnerable to this bug: it downloads the attacker's file only if you actually tap the attachment to open it, which is as it should be. As a bonus, you can later set up to exchange cryptographically secure messages with other TextSecure users (and with Signal users on iOS), further thwarting the NSA.

So here's what I believe you can do to avoid this bug. The instructions below might vary somewhat by Android version; they work for my phones, but might need some modification for yours. Updates in the comments would be welcome!

First, install TextSecure. You can get it from the Google Play App Store as usual, or from Google's Play Store Web site, which will let you install it on your phone: https://play.google.com/store/apps/details?id=org.thoughtcrime.securesms&hl=en

Second, make TextSecure your default SMS/MMS app: Settings -> "More ..." -> Default SMS app. Select TextSecure from the popup list.

You are now done. Phew! But read on for how to get bonus points.

For Bonus Points

Before I switched to TextSecure, I figured it was probably also a good idea to disable auto-download of MMS messages in both Hangouts and Messaging, just in case. (You can also do these steps after you've installed TextSecure as above, if you've already done that.)

In Hangouts: 1. Menu (three horizontal bars at upper left) -> Settings. 2. If Hangouts isn't already your SMS app, you need to tap "SMS disabled" and say "Yes"; otherwise, the menu item should already say "SMS enabled" and you can skip this step. 3. Uncheck "Auto retrieve MMS."

In Messaging: 1. Menu (three dots at bottom right) -> Settings. 2. If Messaging isn't already your SMS app, you need to tap "SMS Disabled" and say "Yes"; otherwise, the menu item should already say "SMS Enabled" and you can skip this step. 3. Uncheck "Auto-retrieve."

Crucially, as the last step, switch back to TextSecure as your default SMS app, as described above.

Boy, does this situation suck. It reminds me of the bad old days of Windows viruses ("don't click on that link you got in email!"). The engineering failure behind it isn't as stupid as those were -- it's a somewhat more sophisticated kind of error -- but the end result for users is basically the same.

Oy vey. :-(
A security gap on the most popular smartphone operating system was discovered by security experts in a lab and is so far not widely exploited. It would let malicious code take over a phone instantly.

Researchers using +NASA  +Hubble Space Telescope  have detected a stratosphere and temperature inversion in the atmosphere of a planet several times the mass of Jupiter, called WASP-33b.

Earth's stratosphere sits above the troposphere, the turbulent, active-weather region that reaches from the ground to the altitude where nearly all clouds top out. In the troposphere, the temperature is warmer at the bottom — ground level — and cools down at higher altitudes. The stratosphere is just the opposite: There, the temperature rises at higher altitudes. This is called a temperature inversion, and it happens because ozone in the stratosphere absorbs some of the sun's radiation, preventing it from reaching the surface and warming this layer of the atmosphere. Similar temperature inversions occur in the stratospheres of other planets in our solar system, such as Jupiter and Saturn.

But WASP-33b is so close to its star that its atmosphere is a scathing 10,000 degrees Fahrenheit, and its atmosphere is so hot the planet might actually have titanium oxide rain.

Please join +Tony Darnell Dr, +Carol Christian and +Scott Lewis as they discuss the atmosphere of this Jupiter-sized #exoplanet with the astronomers who made the observations.

Tonight! 7pm Pacific: talking Einstein & relativity at KPCC in Pasadena. Livestream here: http://www.scpr.org/events/2015/07/22/1735/e--mc2/
Relativity.  It's nearly as famous as the physicist who rocked the world when he revealed it, first with the special theory in 1905, and then with his General Theory of Relativity published November 25, 1915.

Thunderstorms in Los Angeles

I spent the morning reading Asimov and drinking coffee. It then began to rain a bit and was incredibly soothing.

Within 20 minutes it turned into a downpour and started to thunderstorm with LOTS of lightning and thunder. It's like I was a kid on Christmas.

Went up to the balcony to grab a quick shot. Only in #LA do you get blue skies while simultaneously raining with thunder and lightning.

We just had 2 hours that looked like a tropical storm north of Chicago, and I happen to work outside. Love the lightning and thunder too...too bad the customers don't.

We're live!! 
 
Have you ever wondered how astronomers simulate the large-scale structure of the universe?  How do they answer questions like, 'What will #JWST show us?' or 'What can we expect to learn from #WFIRST ?'

The Space Telescope Science Institute is hosting a mini-workshop this week featuring techniques for simulating the universe where they delve into these questions and many more.

This workshop will focus on the interface of models and survey design: how can we best inject and extract astrophysical insight into and from data simulations?

One of the main aims is to identify common ground between various ongoing data simulation efforts associated with diverse facilities on the ground and in space (e.g., ELTs, JWST, LSST, PanSTARRS, WFIRST, ALMA, Euclid etc.).

Please join +Tony Darnell Dr +Carol Christian and +Scott Lewis as they discuss simulating the universe with astronomers +Molly Peeples and Joshua Peek.  We look forward to hearing your comments and questions as well!

Hubble finds interesting characteristics in exoplanet atmospheres!

The more we study exoplanets, the more and more we see similarities between our home and those worlds light-years away from us.

WASP-33b has some extremely interesting atmospheric characteristics and is the topic of tomorrow's ‪#‎HubbleHangout‬ with the +Hubble Space Telescope team: +Tony Darnell, Dr. +Carol Christian and +Scott Lewis as well as the scientists involved in the discovery!

#Space   #Science   #Hubble25   #Exoplanet   #WASP33b   #Hubble  
The exoplanet WASP-33b's atmosphere's been observed by the Hubble Space Telescope and scientists have discovered some extremely interesting characteristics in its atmosphere! Tune in for the #HubbleHangout on Thursday, 23 July 2015 to see the live discussion with the Hubble team and the scientists involved!

Hubble discovers intriguing atmosphere on exoplanet!

Tomorrow's #HubbleHangout  is delving into the wondrous world of exoplanets and their atmospheres. 

The +Hubble Space Telescope has detected not only a stratosphere on the exoplanet WASP-33b, but has noticed some interesting properties within it. There's a temperature inversion in its stratosphere, very similar to how our own atmosphere works, as well as Jupiter's and Saturn's!

Join +Tony Darnell, +Carol Christian and me tomorrow at noon Pacific, 3pm Eastern as we host the show with the phenomenal astronomers who used #Hubbl  to make the observations.

Dinner is served!

Well my kitchen is completely put together now, except for maybe a few non-important things I'll pick up in the next few weeks.

Glad to get back to cooking simple meals for myself in my new apartment.

And then for dessert, I'll be having white peaches, black plums, raspberries and blackberries with Greek yogurt.
