Ever wondered what Hawaii’s famous waves look like from the inside? Marco Mitre, a photographer and noncommissioned officer in the U.S. Army, shares the beauty of the coast along the Hawaiian island of Oahu. The spectacular palette of colors from the waves reflecting the summer sun is enough to transport you to dreams of the tropical Pacific. (Caters News)
Obviously this death wave is coming and it’s put people in various places where they’re going to have to remain for years,” he tells us. “Whether or not that indicates a time jump, we certainly are going to find these characters either on the ground or—if, in fact, anybody makes it to space—in space, or perhaps even stuck on the ground, having changed. [Everyone is] having to deal with a very, very different planet,” Rothenberg says. “There is no survivable spaces on this planet after the death wave rolls past so I think that sets up for a really intense story in the bunker where we know 1200 people are safe–at least from outside threats. And you know, the same thing will go for any survivors wherever they happen to be. It’s going to be a changed landscape literally and figuratively and psychologically.
ASTRONOMERS MAKE THE LARGEST MAP OF THE UNIVERSE YET
Astronomers with the Sloan Digital Sky Survey (SDSS) have created the first map of the large-scale structure of the universe based entirely on the positions of quasars. Quasars are the incredibly bright and distant points of light powered by supermassive black holes.
“Because quasars are so bright, we can see them all the way across the universe,” said Ashley Ross of the Ohio State University, the co-leader of the study. “That makes them the ideal objects to use to make the biggest map yet.”
The amazing brightness of quasars is due to the supermassive black holes found at their centers. As matter and energy fall into a quasar’s black hole, they heat up to incredible temperatures and begin to glow. It is this bright glow that is detected by a dedicated 2.5-meter telescope here on Earth.
“These quasars are so far away that their light left them when the universe was between three and seven billion years old, long before the Earth even existed,” said Gongbo Zhao from the National Astronomical Observatories of Chinese Academy of Sciences, the study’s other co-leader.
To make their map, scientists used the Sloan Foundation Telescope to observe an unprecedented number of quasars. During the first two years of the SDSS’s Extended Baryon Oscillation Spectroscopic Survey (eBOSS), astronomers measured accurate three-dimensional positions for more than 147,000 quasars.
The telescope’s observations gave the team the quasars’ distances, which they used to create a three-dimensional map of where the quasars are. But to use the map to understand the expansion history of the universe, they had to go a step further, using a clever technique involving studying “baryon acoustic oscillations” (BAOs). BAOs are the present-day imprint of sound waves which travelled through the early universe, when it was much hotter and denser than the universe we see today. But when the universe was 380,000 years old, conditions changed suddenly and the sound waves became “frozen” in place. These frozen waves are left imprinted in the three-dimensional structure of the universe we see today.
The good news about these frozen waves – the original baryon acoustic oscillations – is that the process that produced them is simple. Thus, we have a good understanding of what BAOs must have looked like at that ancient time. When we look at the three-dimensional structure of the universe today, it contains these same BAOs grown out to a huge scale by the expansion of the universe. The observed size of the BAO can be used as a “standard ruler” to measure distances. Just as by using the apparent angle of a meter stick viewed from the other side of a football field, you can estimate the length of the field. “You have meters for small units of length, kilometres or miles for distances between cities, and we have the BAO scale for distances between galaxies and quasars in cosmology,” explained Pauline Zarrouk, a PhD student at the Irfu/CEA, University Paris-Saclay, who measured the projected BAO scale.
Astronomers from the SDSS have previously used the BAO technique on nearby galaxies and then on intergalactic gas distributions to push this analysis farther and farther back in time. The current results cover a range of times where they have never been observed before, measuring the conditions when the universe more than two billion years before the Earth formed.
The results of the new study confirm the standard model of cosmology that researchers have built over the last twenty years. In this standard model, the universe follows the predictions of Einstein’s general theory of relativity – but includes components whose effects we can measure, but whose causes we do not understand. Along with the ordinary matter that makes up stars and galaxies, the universe includes dark matter – invisible yet still affected by gravity – and a mysterious component called “dark energy.” Dark energy is the dominant component at the present time, and it has special properties that cause the expansion of the universe to speed up.
“Our results are consistent with Einstein’s theory of general relativity,” said Hector Gil-Marin, a researcher from the Laboratoire de Physique Nucléaire et de hautes Énergies in Paris who undertook key parts of the analysis. “We now have BAO measurements covering a range of cosmological distances, and they all point to the same thing: the simple model matches the observations very well.”
Even though we understand how gravity works, we still do not understand everything – there is still the question of what exactly dark energy is. “We would like to understand dark energy further,” said Will Percival from the University of Portsmouth, who is the eBOSS survey scientist. “Surveys like eBOSS are helping us to build up our understanding of how dark energy fits into the story of the universe.”
The eBOSS experiment is still continuing, using the Sloan Telescope at Apache Point Observatory in New Mexico, USA. As astronomers with eBOSS observe more quasars and nearby galaxies, the size of their map will continue to increase. After eBOSS is complete, a new generation of sky surveys will begin, including the Dark Energy Spectroscopic Instrument (DESI) and the European Space Agency Euclid satellite mission. These will increase the fidelity of the maps by a factor of ten compared with eBOSS, revealing the universe and dark energy in unprecedented detail.
IMAGE….A slice through largest-ever three-dimensional map of the universe. Earth is at the left, and distances to galaxies and quasars are labeled by the lookback time to the objects (lookback time means how long the light from an object has been traveling to reach us here on Earth). The locations of quasars (galaxies with supermassive black holes) are shown by the red dots, and nearer galaxies mapped by SDSS are also shown (yellow). The right-hand edge of the map is the limit of the observable Universe, from which we see the cosmic microwave background (CMB) – the light “left over” from the Big Bang. The bulk of the empty space in between the quasars and the edge of the observable universe are from the “dark ages,” prior to the formation of most stars, galaxies, or quasars.

Zootopia Fanfiction Take A Stand: Star of Ceartais Ch. 5 - The Heart of Sherwood
(AN/ Hey folks it’s Garouge/ Crewefox here with another chapter of Star of Ceartais. Thank you to everyone who liked, followed, faved, reviewed and reblogged the last chapter, you are all amazing…and sorry, not sorry, for the cliffhanger last week. Also I want to thank the awesome SOC development team of @raykamino, @nick-and-judy-daily, @senny74 and @alexboehm55144 for helping with ideas and beta reading this chapter, I could not do this without you guys. So without further ado let’s get cracking with this chapter…)
As soon as Robyn and Hannah had contacted Jack, the buck rabbit had ran into his Skye’s home office who was busy trying to mobilize all the Major Crimes Bureau agents under her command to help with the impending relief effort, he had to shout that Hannah and Robyn were injured and trapped to get her attention. Skye immediately hung up the phone and started forming a plan of rescue, the nearest MCB office was less than three miles away and it had a helicopter on it’s grounds, the husband and wife drove to the field office and Jack quickly selected two agents with medic training to accompany him on the rescue mission while Skye despite being worried sick stayed at the field office to coordinate all the other agents. It’s at this point Skye realised one important detail that both her and Jack neglected; they hadn’t contacted Nick and Judy, Skye cursed herself for this, she had been so focused on the rescue she had forgotten to call them. The resulting phone call was panicked, scream filled and sound tracked with sobs but soon enough a message came through on the radio that Hannah and Robyn had been found and they were getting rushed to Savannah Central General Hospital via the chopper. Nick and Judy were told to get there as soon as they could…
“Oh god, oh god, oh god.” Judy repeated with rushed breaths, she was in the passenger seat of the family car as Nick drove through the wrecked streets of Savannah Central with the hospital less than a block away.
The reports spread fast, the death of Dr Junkenstien and his horrific creation. Sighs of relief spread across the land.
And the little shed deep in the heart of the forest.
Junkenstien waved the news sheet at his monster, sitting calmly by the fire.
“Fools, the whole lot of them! Those bloody mercs couldn’t see what was right in their faces!”
A soft knock on the door and he grinned wider, swinging it open.Leaking hay and straw, a lurching figure staggered inside, draped in the tattered remnants of Junkenstiens second best lab coat. Arrows sprouted harmlessly from his back, intermingled with bullet holes and frayed edges from the alchemists poison grenades.
“Good work, hayseed! You fooled ‘em good! Right, come inside and lets get you fixed up.”
His creations safe, the mad doctor let himself relax. Sometime soon the witch would come. Sometime soon she would call in the favour.

I know there has been and will be a lot of attention on the fact that the former President Park Geun-hye of Korea is a woman and that her partner in corruption Choi Soon-sil is also a woman, as are major players in the scandal (including Choi’s niece and daughter) who were involved in or benefited from the corruption that led to Park’s impeachment.
That’s less than half the story, though, because in so many ways this impeachment was kicked off, driven, and ended by women.
Do you know how the allegations of Park and Choi’s corruption entered the public consciousness? It was due to the student protests at Ewha Womans University (full disclosure: my alma mater and current place of work), the oldest and largest women’s university in Korea. In 2016 students and alumnas went on a months-long protest of the school’s decision to institute a continuing-education degree program. During the tumultuous events the protesters raised suspicions that a student had received illegal favors during the admissions process and later in class attendance and grading.

That student was Jeong Yura, former competitive rider for the Korean team and Choi Soon-sil’s daughter. The revelations about Jeong kicked off a wave of news reports and later government investigations that led to nationwide protests.
The protests pushed the National Assembly, our legislature, to decide to refer the President to the Constitutional Court for impeachment. The leaders of two of the three opposition parties that voted to impeach? Assemblywomen Chu Mi-ae and Shim Sang-jeong.

And the acting Chief Justice of the Constitutional Court who announced the court’s decision to impeach Park? Justice Lee Jeong-mi, a woman.

Whoops no, that’s a picture of her coming to work in hair rollers on the day of the decision. We’ve all been there, girl, you’re good.

So I do not want to hear a word about how this impeachment says anything bad about the qualifications of women. The impeachment is not a story of one gender against another. It is a story of privilege versus merit, where courageous and conscientious men and women came together against a political dynasty that illegally used power for private gain. It is the story of our democracy, not fodder for anyone’s misogynistic agenda.
You might have noticed that we’re inviting some special guests from the media and our community to be part of a live audience for this premiere. They’ll be among the first players to get some hands-on time with Destiny 2 immediately after the conclusion of the livestream. The PS4 and PC versions of the game will be on display, so you should expect another wave of news, coverage, and content to dig into after the event is over.
