Spiraling Supermassive Black Holes : Do black holes glow when they collide? When merging, co-orbiting black holes are sure to emit a burst of unusual gravitational radiation, but will they emit light, well before that, if they are surrounded by gas? To help find out, astrophysicists created a sophisticated computer simulation. The simulation and featured resulting video accurately depicts two spiraling supermassive black holes, including the effects of Einstein’s general relativity on the surrounding gas and light. The video first shows the system from the top, and later from the side where unusual gravitational lens distortions are more prominent. Numerical results indicate that gravitational and magnetic forces should energize the gas to emit high-energy light from the ultraviolet to the X-ray. The emission of such light may enable humanity to detect and study supermassive black hole pairs well before they spiral together. via NASA

So There Are Black Holes, but there is also White Holes. AKA WORMHOLES. Theoretically.
Confused and scared and excited by Space.
You learn something new everyday, especially in Space Club. Based on the theory of general relativity, a white hole is a hypothetical region of space time which cannot be entered, but matter and light escape from it. So it is basically the opposite of a Black Hole.
Black holes sucks everything in and nothing escapes and white holes pushes everything out.
White holes have never been observed, but the fact that we now have an image of a black hole, we may be getting closer.
I have been reading so much about White Holes and to be honest I am still SO CONFUSED. One theory about white holes is that objects falling towards it would never reach the center (or the event horizon as it is called in science) but would keep falling until it reaches the event horizon of a black hole. Confused? Me too.
Here is a picture:
So to recap, one theory is that Black Holes open up to White Holes, aka a WORMHOLE. That is right. The Wormhole theory is basically you go into a black hole and you come out of a white hole. And vice versa I guess? Meaning a sort of bridge or bend in space time. UM OK? Also - this is an incredibly watered down version of these theories and there is so much more info that goes into this. Here is a another picture that kind of shows a black hole connected to a white hole.

ON HER WAY TO MARS
19-year old Abigail Harrison has transformed from space fan to international science ambassador.
By Erin Winick for Mission Magazine
Many kids dream of being astronauts when they grow up. However, few take action towards this goal like 19-year-old Abigail Harrison. Harrison is passionate about using her journey towards becoming the first astronaut to step on Mars as a learning experience for the world.
Harrison has already made a difference in the world of science communication and space exploration with her blog, Astronaut Abby, Adventures of an Aspiring Astronaut, which has spiraled off into many science outreach programs, including her nonprofit, The Mars Generation. She has become an important voice in science communication with this nonprofit a reaching more than 10 million people in its first year of operation and more than 600 students from around the world participating in its Student Space Ambassador program.
“My favorite The Mars Generation programs are the Student Space Ambassador Program and Space Camp Scholarship Program,” Harrison said. “It’s amazing to empower students to dream big, act big and inspire others.
Her organization continues to grow and offer programs to excite the public about the importance of human space exploration. Visit, donate, and support their work HERE.
“TheMarsGeneration.org is the nonprofit that evolved from my outreach work that I started at age 13 and continues through today,” Harrison said. “I launched the nonprofit last year when I started Wellesley College as a way to empower others to help spread the important messages of why STEM and space exploration are important to society and also exciting people about going to Mars.”
Harrison knows about the importance of exposing society to space travel. Growing up in Minnesota, she was not readily exposed to the space industry, but was excited about space and human space exploration from as young as she can remember.
“The actual space program did not start to heavily influence me until I was in 7th grade when I went to Space Camp in Huntsville, Alabama and experienced the U.S. Space and Rocket Center, my first NASA center visit and first astronaut meeting,” Harrison said. “That was an amazing experience and certainly solidified what I already knew. I wanted to become a scientist, work in the space industry and become an astronaut.”
Harrison became ‘Astronaut Abby’ during the creation of an 8th grade State History Day Project titled Debate and Diplomacy: The History of the ISS. From here she started heavily using social media to engage with the science world and eventually gained a close relationship with NASA, writing a blog for them and being featured on their education website.
Harrison’s personal following exploded after this and continues to grow, now touting a social media audience of over 600,000 fans and followers across a variety of platforms. You can tune into her social channels to see everything from her first adventures with flying lessons to speaking at Space Camp and now even traveling the world. Her social influencer status has grown so much that she has evolved into an international ambassador for science and space exploration.
The United Arab Emirates Space Agency has invited Harrison to tour the Emirates Mars Mission and Mohammed bin Rashid Space Centre (MBRSC) this month. The MBRSC holds the Hope Probe, which is currently in the manufacture stages, that plans to launch in 2020 for its journey to Mars. Harrison connected with the UAE Space Agency about one-and-a-half years ago to include her in their first issue of a space magazine they were launching and has maintained the relationship to this day.
Harrison considered meeting Sahda, a 13-year-old Student Space Ambassador for the Mars Generation, one of the most inspiring moments of her experience. Harrison was proud when Sahda told her, “without the Mars Generation, I never would have had the confidence to become a public speaker and start a space club at my school. Thank you.” (’Astronaut Abby’s Journey to Mars’ – Wellesley College News)
“Young people represent an important influence for STEM and space exploration,” Mona Al Qemzi the Assistant Director General at the MBRSC said. “We are delighted to host a bright, motivated, and inspiring voice of the Mars generation and we look forward to having Abby share her stories with our community and agency.”
This trip comes as the United States and United Arab Emirates (UAE) entered into an agreement to cooperate in aeronautics research, and the exploration and use of airspace and outer space for peaceful purposes back in June of 2016, with a focus on the cooperation in the exploration of Mars. This agreement also included the aim of the United States and UAE to collaborate on the creation and implementation of education and public outreach programs and joint workshops, with the goal of facilitating the exchange of scientific data, scientists, engineers, and views.
In the wake of this agreement, Harrison will also get the chance to speak about the importance of STEM education and deep space human space exploration to the future of humanity at Project Space, a conference bringing some of the top minds in space to Dubai.
“The majority of my talk will focus on inspiring people to continue to work towards human Mars exploration and will explain why my generation is the Mars generation and why going to Mars is vital to societal advancement,” Harrison said.

However, this is not Harrison’s first international science experience. In 2013 she traveled to Russia as a special guest of Italian Astronaut Luca Parmitano to be a part of a legendary Soyuz launch. After the launch, Harrison served as Parmitano’s Earth Liaison, sharing Parmitano’s space mission with her followers and other young people interested in space.
While traveling, Harrison has and will continue to share all of her experiences with her followers. Social media has been a key to her outreach, ranging from Facebook to Instagram to Twitter. For this upcoming trip to the UAE, Harrison will also be putting a new emphasis though sharing on Youtube, with the goal of bringing more people into the experience in an immersive way.
Abby was not only a Teen Hero Finalist, but also presented at the Short Awards alongside former NASA astronaut Mike Massimino! Read her blog entry on her experience HERE.
Now a sophomore in college, Harrison is excited to continue and extend her mission and experiences in science, working towards her first steps on Mars.
“I really am enjoying every moment as I live it,” Harrison said. “I am looking forward to landing a lab internship in astrobiology this summer, I am looking forward to earning my pilots license and growing my nonprofit to be sustainable and something that lasts beyond my lifetime.”

I remain continually humbled and impossibly proud of this young woman, and others like her who have committed themselves to sharing their dreams and aspirations for the future with the present generations of today. While in peak PR mode for @astronautfilm, I coordinated a classroom screening of ‘I want to be an Astronaut’ via a Christa McAuliffe School in Massachusetts. Afterwards, Abby and I shared a live Google Hangout together to talk to the audience. Since then, ‘Astronaut Abby’ has truly launched herself - pun indeed intended - on a trajectory women throughout history would respect, as she’s embraced all social media platforms and utilized so many of her connections and relationships she’s forged to strengthen an already broad web of influence and inspiration the world over.
Thank you for never giving up, @astronautabby and for doing you, for us.
Don’t miss Abby’s TED Talk below, as well as this related post regarding Abby’s company of aspiring astronauts.
“Dream big. Act big. Inspire others.” — Abigail “Astronaut Abby” Harrison
An incredibly enthusiastic, intelligent, visionary, and motivated young woman, Abigail Harrison is setting her sites on being the first astronaut to land on Mars. Starting in 5th grade with the GEMS program (Girls in Engineering, Mathematics and Science) to being invited as guest blogger for NASA’s ISS blog, corresponding with Italian astronaut Luca Parmatano, and attending the legendary Russian Soyuz space launch as a VIP guest, Abby is well on her way. Currently, she juggles dual high school and college courses, gymnastics, blogging, and public appearances. With a deep appreciation for space exploration of the past, Abby has already embraced its future. — @tedx @ted
Solar System: Things to Know This Week
Jupiter, we’ve got quite the photoshoot planned for you. Today, our Juno spacecraft is flying directly over the Great Red Spot, kicking off the first-ever close-up study of this iconic storm and passing by at an altitude of only 5,600 miles (9,000 kilometers). In honor of this historic event, below are 10 things to know about the planet’s most famous feature.
1. A Storm That Puts Others to Shame
The Great Red Spot is a gigantic, high-pressure, ancient storm at Jupiter’s southern hemisphere that’s one of the longest lasting in the solar system. It’s so large, about 1.3 Earths could fit inside of it. And you can bet you’ll get swept away—the storm’s tumultuous winds peak at about 400 mph.
2. How Old Is It?
The Great Red Spot has been swirling wildly over Jupiter’s skies for the past 150 years—maybe even much longer. While people saw a big spot on Jupiter when they started stargazing through telescopes in the 1600s, it’s still unclear whether they were looking at a different storm. Today, scientists know the Great Red Spot has been there for a while, but they still struggle to learn what causes its swirl of reddish hues.
3. Time for That Close-Up
Juno will fly over the Great Red Spot about 12 minutes after the spacecraft makes the closest approach to Jupiter of its current orbit at 6:55 p.m. on July 10, PDT (9:55 p.m. on July 10, EDT; 1:55 a.m. on July 11, Universal Time). Juno entered orbit around Jupiter on July 4, 2016.
4. Oh, So Mysterious
Understanding the Great Red Spot is not easy, and it’s mostly Jupiter’s fault. The planet a thousand times as big as Earth and consists mostly of gas. A liquid ocean of hydrogen surrounds its core, and the atmosphere consists mostly of hydrogen and helium. That translates into no solid ground (like we have on Earth) to weaken storms. Also, Jupiter’s clouds make it hard to gather clear observations of its lower atmosphere.

5. Help From Hawaii
To assist Juno’s investigation of the giant planet’s atmosphere, Earth-based telescopes lent their helpful eyes. On May 18, 2017, the Gemini North telescope and the Subaru Telescope—both located on Hawaii’s Mauna Kea peak—simultaneously examined Jupiter in very high resolutions at different wavelengths. These latest observations helped provide information about the Great Red Spot’s atmospheric dynamics at different depths and at other regions of Jupiter.
6. Curious Observations
Observations from Subaru showed the Great Red Spot “had a cold and cloudy interior increasing toward its center, with a periphery that was warmer and clearer,” said Juno science team member Glenn Orton of our Jet Propulsion Laboratory, Pasadena, California. “A region to its northwest was unusually turbulent and chaotic, with bands that were cold and cloudy, alternating with bands that were warm and clear.”

7. Hot in Here
Scientists were stumped by a particular question: Why were the temperatures in Jupiter’s upper atmosphere comparable to those found at Earth, even though Jupiter is more than five times the distance from the sun? If the sun isn’t the heat source, then what is? Turns out, the storm in the Great Red Spot produces two kinds of turbulent energy waves that collide and heat the upper atmosphere. Gravity waves are much like how a guitar string moves when plucked, while acoustic waves are compressions of the air (sound waves). Heating in the upper atmosphere 500 miles (800 kilometers) above the Great Red Spot is thought to be caused by a combination of these two wave types “crashing,” like ocean waves on a beach.
8. Color Theory
Scientists don’t know exactly how the Great Red Spot’s rich colors formed. Studies predict Jupiter’s upper atmosphere has clouds consisting of ammonia, ammonium hydrosulfide, and water, but it’s still unclear how or even whether these chemicals react. “We’re talking about something that only makes up a really tiny portion of the atmosphere,” said Amy Simon, an expert in planetary atmospheres at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “That’s what makes it so hard to figure out exactly what makes the colors that we see.” Over at NASA’s Jet Propulsion Laboratory in Pasadena, California, researchers concluded that the ruddy color is likely a product of simple chemicals being broken apart by sunlight in the planet’s upper atmosphere. “Our models suggest most of the Great Red Spot is actually pretty bland in color, beneath the upper cloud layer of reddish material,” said Kevin Baines, a Cassini scientist at JPL.
9. Been There, Haven’t Seen That
In January and February 1979, NASA’s Voyager 1 spacecraft zoomed toward Jupiter, capturing images of the Great Red Spot during its approach. Still, we’ve never been as close as we’re about to get during Juno’s flyover on July 10.
10. Simply Beautiful
This image of a crescent Jupiter and the iconic Great Red Spot was created by a citizen scientist, Roman Tkachenko, using data from Juno’s JunoCam instrument. JunoCam’s raw images are available here for the public to peruse and enhance.Want to learn more? Read our full list of the 10 things to know this week about the solar system HERE.
