The Future Is Kelp

Navigating Space by the Stars

A sextant is a tool for measuring the angular altitude of a star above the horizon and has helped guide sailors across oceans for centuries. It is now being tested aboard the International Space Station as a potential emergency navigation tool for guiding future spacecraft across the cosmos. The Sextant Navigation investigation will test the use of a hand-held sextant that utilizes star sighting in microgravity.

Candle + Book Giveaway

Hey everyone! The Literary Snob is teaming up with The Happy Bard Candle Co. to do a double giveaway this September. We’re all on the same trivia team in the real world (Sean Bean Lives!) and I absolutely love Happy Bard’s literary inspired candles. They’re about to release their next line of literary candles and one of the new scents will be a fan submission! So we’re holding a contest and double giveaway to find the fairest combo in the land. 

Reblog this post with your submission for a literary candle scent. You can send in as many submissions as your heart desires and tag anyone who dreams of being a candle virtuoso. The Happy Bard Candle Co. will pick their favorite submission at the end of the contest, create the candle, and send it to you! Plus I will send the winner one of the newly released Vintage Minis of your choice.

GIVEAWAY RULES

Have fun and be creative!

RULES

There is no limit on submissions, so reblog away! Currently, The Happy Bard Candle Co. cannot ship internationally, so anybody can participate but only those in the U.S. can win. Contest ends Saturday, Sept. 30 at midnight.

We look forward to seeing what everyone comes up with! Plus I might throw in an extra prize for whoever makes me laugh the hardest. Good luck!

This is why you should always speak your mind

I made the top comment on the Star Wars Facebook, criticizing the Benioff and Weiss hire.

I present: comments from three hundred upset men (and women!) and why none of them have shaken my belief in how bad a hire this is.

I knew my remark would be unpopular and met with nasty comments, misguided statements about Game of Thrones and the film industry, insinuations that there aren’t any good women or nonwhite directions, couple of lewd comments about my sex life. There is truth to the adage: Facebook is a cesspool.

What I didn’t know is that I would get enough attention to make the top comment.

At the time of writing, sixty hours after initial posting, it’s running a little less than 80% laugh reactions—so, people thinking I’m a moron—and it’s running about 1,100 reactions and 324 replies.

Unfortunately for my would-be adversaries, I don’t debate on Facebook and it is a favorite pastime to read the vitriol and mediocre hash slung in my direction as if it’ll have any effect on my self-esteem. Fortunately, you don’t have to do the same. I present: the major response patterns and why they don’t hold any water.

He always fell for puppies.

If you’re looking for cute you’ve come to the right place! Thanks to the Naval Photographic Center, which filmed many of President Ford’s activities, we have footage of Liberty’s puppies playing in the White House Rose Garden. President Ford, Mrs. Ford, and Susan had a photo shoot with the little golden retrievers on November 5, 1975, followed by frolicking and general adorableness.

We’ve highlighted some of our favorite moments above. Watch the full video and pick your own!

I wonder what affect these types of events have on human perceptions

September 2017 Was 🔥 on the Sun

The Sun started September 2017 with flair, emitting 31 sizable solar flares and releasing several powerful coronal mass ejections, or CMEs, between Sept. 6-10.

Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth’s atmosphere to physically affect humans on the ground, however — when intense enough — they can disturb the atmosphere in the layer where GPS and communications signals travel. 

CMEs are massive clouds of solar material and magnetic fields that erupt from the Sun at incredible speeds. Depending on the direction they’re traveling in, CMEs can spark powerful geomagnetic storms in Earth’s magnetic field.

As always, we and our partners had many missions observing the Sun from both Earth and space, enabling scientists to study these events from multiple perspectives. With this integrated picture of solar activity, scientists can better track the evolution of solar eruptions and work toward improving our understanding of space weather.

The National Oceanic and Atmospheric Administration (NOAA)’s Geostationary Operational Environmental Satellite-16, or GOES-16, watches the Sun’s upper atmosphere — called the corona — at six different wavelengths, allowing it to observe a wide range of solar phenomena. GOES-16 caught this footage of an X9.3 flare on Sept. 6, 2017. 

This was the most intense flare recorded during the current 11-year solar cycle. X-class denotes the most intense flares, while the number provides more information about its strength. An X2 is twice as intense as an X1, an X3 is three times as intense, and so on. GOES also detected solar energetic particles associated with this activity.

Our Solar Dynamics Observatory captured these images of X2.2 and X9.3 flares on Sept. 6, 2017, in a wavelength of extreme ultraviolet light that shows solar material heated to over one million degrees Fahrenheit.

JAXA/NASA’s Hinode caught this video of an X8.2 flare on Sept. 10, 2017, the second largest flare of this solar cycle, with its X-ray Telescope. The instrument captures X-ray images of the corona to help scientists link changes in the Sun’s magnetic field to explosive solar events like this flare.

Key instruments aboard our Solar and Terrestrial Relations Observatory, or STEREO, include a pair of coronagraphs — instruments that use a metal disk called an occulting disk to study the corona. The occulting disk blocks the Sun’s bright light, making it possible to discern the detailed features of the Sun’s outer atmosphere and track coronal mass ejections as they erupt from the Sun.

On Sept. 9, 2017, STEREO watched a CME erupt from the Sun. The next day, STEREO observed an even bigger CME. The Sept. 10 CME traveled away from the Sun at calculated speeds as high as 7 million mph, and was one of the fastest CMEs ever recorded. The CME was not Earth-directed: It side-swiped Earth’s magnetic field, and therefore did not cause significant geomagnetic activity. Mercury is in view as the bright white dot moving leftwards in the frame.

Like STEREO, ESA/NASA’s Solar and Heliospheric Observatory, or SOHO, uses a coronagraph to track solar storms. SOHO also observed the CMEs that occurred during Sept. 9-10, 2017; multiple views provide more information for space weather models. As the CME expands beyond SOHO’s field of view, a flurry of what looks like snow floods the frame. These are high-energy particles flung out ahead of the CME at near-light speeds that struck SOHO’s imager.

Our Interface Region Imaging Spectrometer, or IRIS, captured this video on Sept. 10, 2017, showing jets of solar material swimming down toward the Sun’s surface. These structures are sometimes observed in the corona during solar flares, and this particular set was associated with the X8.2 flare of the same day.  

Our Solar Radiation and Climate Experiment, or SORCE, collected the above data on total solar irradiance, the total amount of the Sun’s radiant energy, throughout Sept. 2017. While the Sun produced high levels of extreme ultraviolet light, SORCE actually detected a dip in total irradiance during the month’s intense solar activity. 

A possible explanation for this observation is that over the active regions — where solar flares originate — the darkening effect of sunspots is greater than the brightening effect of the flare’s extreme ultraviolet emissions. As a result, the total solar irradiance suddenly dropped during the flare events. 

Scientists gather long-term solar irradiance data in order to understand not only our dynamic star, but also its relationship to Earth’s environment and climate. We are ready to launch the Total Spectral solar Irradiance Sensor-1, or TSIS-1, this December to continue making total solar irradiance measurements.

The intense solar activity also sparked global aurora on Mars more than 25 times brighter than any previously seen by NASA’s Mars Atmosphere and Volatile Evolution, or MAVEN, mission. MAVEN studies the Martian atmosphere’s interaction with the solar wind, the constant flow of charged particles from the Sun. These images from MAVEN’s Imaging Ultraviolet Spectrograph show the appearance of bright aurora on Mars during the September solar storm. The purple-white colors show the intensity of ultraviolet light on Mars’ night side before (left) and during (right) the event.
