She has been super popular on the internet as of late, because last year she realized that within her DNA was a gene called BRCA. BRCA genes are associated with extremely high risk of breast cancer, and one way to lessen that cancer risk is to remove all breast tissue — WHICH. SHE. DID. She got a double mastectomy at 26 years old to prevent future breast cancers. It’s amazing. She’s a queen. P.P.S — Now, not only does Sarafina talk publicly about supernovas, astrophysics, and STEM, but about cancer, BRCA, breast surgery, mastectomies, and be a cancer “previvor” as she calls it.

In 2015, scientists discovered the telltale signal from ripples of spacetime sweeping over the Earth. It was the very first direct detection of gravitational waves, generated by the merger of two massive black holes 1.3 billion light-years away. This discovery was the culmination of decades of research and construction of huge instruments called interferometers to detect the warping of spacetime caused by gravitational waves. Today, the most advanced detectors, the LIGO/VIRGO collaboration, have turned up over 50 gravitational wave discoveries - on average one every week - allowing astronomers to perceive the Universe in a completely different way. What new gravitational wave instruments are in the works, and what does the future hold for this relatively new field of study?

Why is Betelgeuse dimming? Is Betelgeuse about to explode? Betelgeuse is a variable red super giant star located in the Orion constellation. Most estimations have it going supernova within the next 100,000 years, but could it be sooner? Dr. Edward Guinan has been studying Betelgeuse and other variable stars from Villanova for over 40 years. He joins John Michael Godier to discuss his recent updates on the fainting and dimming of Betelgeuse.

Emanuele Berti of Johns Hopkins University Black holes hold the key to some of the pressing mysteries in modern science. Whether in isolation or in binary systems, they are excellent laboratories to probe high-energy physics and Einstein’s theory of gravity. The detection of gravitational waves from binary mergers marked the dawn of a new era in astronomy, and planned space-based detectors will open a new observational window at low frequencies. Gravitational waves from compact binaries carry important information on their astrophysical formation mechanisms, and on the evolution of the universe as a whole. Join us for a discussion about how gravitational-wave detectors can not only advance our understanding of black hole formation and growth, but also search for potential “smoking guns” of new physics.

On October 16, 2017, astronomers excitedly reported the first detection of electromagnetic waves, or light, from a gravitational wave source. Now, a year later, researchers are announcing the existence of a cosmic relative to that historic event. The discovery was made using data from a host of telescopes including NASA’s Chandra X-ray Observatory. The object of the new study, called GRB 150101B, was first reported as a gamma-ray burst detected by Fermi in January 2015. This detection and follow-up observations show that this new object shares remarkable similarities to the neutron star merger and gravitational wave source discovered by the Advanced Laser Interferometer Gravitational Wave Observatory, and its European counterpart Virgo in 2017 known as GW170817. The latest study concludes that these two separate objects may, in fact, be related. The researchers think both GRB 150101B and GW170817 were most likely produced by the same type of event: the merger of two neutron stars. This is a catastrophic collision that generated a narrow jet, or beam, of high-energy particles. The jet produced a short, intense burst of gamma rays, a high-energy flash that can last only seconds. This was followed by an afterglow in optical light that lasted a few days and X-ray emission that lasted much longer. Scientists think both of these events involved kilonovas, that is, powerful explosions that release large amounts of energy and can produce elements like gold, platinum and uranium. Understanding these explosions helps astronomers trace our cosmic ancestry. There is still a lot to learn about these events, but Chandra is poised to help in this new era of combined gravitational wave and electromagnetic investigations into our Universe.

The spectacular merger of two neutron stars that generated gravitational waves announced last fall likely did something else: birthed a black hole. This newly spawned black hole would be the lowest mass black hole ever found. A new study analyzed data from NASA's Chandra X-ray Observatory taken in the days, weeks, and months after the detection of gravitational waves by the Laser Interferometer Gravitational Wave Observatory, or LIGO, and gamma rays by NASA's Fermi mission on August 17, 2017. While nearly every telescope at professional astronomers' disposal observed this source, known officially as GW170817, X-rays from Chandra are critical for understanding what happened after the two neutron stars collided. From the LIGO data astronomers have a good estimate that the mass of the object resulting from the neutron star merger is about 2.7 times the mass of the Sun. This puts it on a tightrope of identity, implying it is either the most massive neutron star ever found or the lowest mass black hole ever found. The previous record holders for the latter are no less than about four or five times the Sun's mass. The Chandra observations are telling, not only for what they revealed, but also for what they did not. If the neutron stars merged and formed a heavier neutron star, then astronomers would expect it to spin rapidly and generate a very strong magnetic field. This, in turn, would have created an expanding bubble of high-energy particles that would result in bright X-ray emission. Instead, the Chandra data show levels of X-rays that are a factor of a few to several hundred times lower than expected for a rapidly spinning, merged neutron star and the associated bubble of high-energy particles, implying a black hole likely formed instead.

Gravitational Wave Astronomy Andrew Fruchter, Space Telescope Science Institute The 2017 Nobel Prize in Physics was awarded for the observation of gravitational waves. This new field transforms our ability to study the universe. For the first time, we can directly observe the mergers of binaries composed of the densest macroscopic objects in the universe—black holes and neutron stars. The results are revolutionary. We have discovered stellar mass black holes far larger than any previously known, and have seen them merge to form even larger black holes. We have seen evidence that neutron star mergers are a major source of the heavy elements in the universe. Dr. Fruchter will provide an introduction to the technology and physics behind the detection of gravitational waves as well as discuss the exciting new results.

Jan. 24, 2018 Dr. Eliot Quataert (University of California, Berkeley) Recently one third of the world's astronomers became involved in observing a distant and violent event, when two neutron stars collided and exploded. This represented the first time in history that a cosmic event was observed with both gravity waves and light -- the birth of "multi-messenger astronomy." Dr. Quataert gives a non-technical history of how we are now able to find gravity waves, what happens during such a merger, and why we now believe that much of the gold, platinum, uranium and other heavy elements in the universe is assembled in such mergers.

More Info: http://www.caltech.edu/news/ligo-and-virgo-make-first-detection-gravitational-waves-produced-colliding-neutron-stars-80082 On Aug. 17, 2017, the Laser Interferometer Gravitational-wave Observatory (LIGO) and Virgo detected, for the first time, gravitational waves from the collision of two neutron stars. The event was not only “heard” in gravitational waves but also seen in light by dozens of telescopes on the ground and in space.

Astronomers unlocked one of the universe's best-kept secrets. Since the '50s, scientists have wondered: Where do most of the elements in the periodic table come from? We know that elements like carbon, oxygen, and nitrogen are forged in the hot, dense cores of massive stars. But even stars aren't powerful enough to create heavy elements like silver, gold, and cesium. Turns out, the origin of 2/3 of the periodic table is unconfirmed. Now, a single event has given scientists a vital clue. Astronomers witnessed the collision of two neutron stars in a distant galaxy located 130 million light years from Earth. Neutron stars are ultra-dense stellar remnants. In fact, they're the densest matter in the universe. When two neutron stars merge, it creates an explosion more powerful than 1,000 supernovae. As the neutron stars spiraled in, they produced gravitational waves. LIGO and VIRGO first detected the waves on Aug. 17. Two seconds later, the Fermi space telescope measured a burst of high-energy radiation from the explosion. But these 2 measurements alone couldn't solve the puzzle. Astronomers needed to see the event in visible light. The first to spot the event with their own eyes was a team with the Carnegie Institute for Science. Initially, the explosion they saw looked bright blue. But after four days it dimmed to a dull red. The red color comes from a specific set of heavy elements that are produced by a process called the ligh r-process. But the blue color is a mystery. Some theorists suggest it's the result of a different set of elements called heavy r-process elements. But data from similar collisions are needed to be sure. This is the first time scientists have combined gravitational wave measurements with visible light. Who knows what new secrets may be unlocked next time?

In these clips, four astronomers discuss the latest result in which NASA's Chandra X-ray Observatory, along with many other telescopes, detected light from a gravitational wave source for the first time. These scientists represent the many who worked very hard since the source's discovery on August 17, 2017, to make this result happen. This discovery is both historic and significant, and it represents a new era of astrophysics. Scientists: Wen-fai Fong, Daryl Haggard, Raffaella Margutti, Eleonora Troja.

Following 16 months of scientific effort, LISA Pathfinder completed its main mission on 30 June 2017, having demonstrated the technology needed to operate ESA’s future LISA space observatory to study gravitational waves – ripples in spacetime predicted by Albert Einstein. On 18 July, the spacecraft was shut down after being placed in a safe disposal orbit. The final command was sent from ESOC, ESA's European Space Operations Centre, at 19:57 CEST that evening. That day, scientists, mission controllers and the mission's management team gathered at ESOC, Darmstadt, Germany, for a presentation on the successes of the mission prior to the shut-down. This video was recorded between 16:00-18:00 CEST, and includes highlight presentations on the mission's achievements.

Gravitation wave theory. On my next break I'll do a quick video! But for now here's a quick sample of what I'll talk about... this blueberry fell into my cup of coffee and caused ripples. On the cosmic scale strong gravitational objects like rapidly spinning neutron stars or black holes orbiting one another can cause gravitational waves aka disruptions in space time in the form of RIPPLES that MOVE at the SPEED OF LIGHT. (**DISCLAIMER MY COFFEE DOES NOT MOVE AT THE SPEED OF LIGHT**) ☕️💡 Woohoo!! I managed to get this on my lunch break haha!! Back to set! Hope you guys like this!!

The LISA Pathfinder mission ends on 18 July 2017 after a successful demonstration of the technology needed to detect gravitational waves in space. These vibrations in spacetime, first predicted by Einstein over a hundred years ago, are produced by huge astronomical events - such as two black holes colliding - and will allow scientists to open new windows into our universe. The success of the LISA Pathfinder mission has paved the way for the newly selected LISA mission which, when built and launched, will detect gravitational waves from objects up to a million times larger than our Sun. The film features interview soundbites from Dr Paul McNamara, LISA Pathfinder Project Scientist, at the European Space Agency’s European Technology and Science facility (ESTEC) in The Netherlands.

We’ve now had multiple detections of gravitational waves, opening up a whole new field: gravitational astronomy. We talk about the detections made so far, and how we can see the Universe in a whole new way.

As with the previous two detections, astronomers have determined that the waves were generated when two intermediate-mass black holes slammed into each other, sending out ripples of distorted spacetime. One black hole had 31.2 times the mass of the Sun, while the other had 19.4 solar masses. The two spiraled inward towards each other, until they merged into a single black hole with 48.7 solar masses. And if you do the math, twice the mass of the Sun was converted into gravitational waves as the black holes merged. These gravitational waves traveled outward from the colossal collision at the speed of light, stretching and compressing spacetime like a tsunami wave crossing the ocean until they reached Earth, located about 2.9 billion light-years away. The waves swept past each of the two LIGO facilities, located in different parts of the United States, stretching the length of carefully calibrated laser measurements. And from this, researchers were able to detect the direction, distance and strength of the original merger. Seriously, if this isn’t one of the coolest things you’ve ever heard, I’m clearly easily impressed. Now that the third detection has been made, I think it’s safe to say we’re entering a brand new field of gravitational astronomy. In the coming decades, astronomers will use gravitational waves to peer into regions they could never see before. Being able to perceive gravitational waves is like getting a whole new sense. It’s like having eyes and then suddenly getting the ability to perceive sound. This whole new science will take decades to unlock, and we’re just getting started. As Einstein predicted, any mass moving through space generates ripples in spacetime. When you’re just walking along, you’re actually generating tiny ripples. If you can detect these ripples, you can work backwards to figure out what size of mass made the ripples, what direction it was moving, etc. Even in places that you couldn’t see in any other way. Let me give you a couple of examples. Black holes, obviously, are the low hanging fruit. When they’re not actively feeding, they’re completely invisible, only detectable by how they gravitational attract objects or bend light from objects passing behind them. But seen in gravitational waves, they’re like ships moving across the ocean, leaving ripples of distorted spacetime behind them. With our current capabilities through LIGO, astronomers can only detect the most massive objects moving at a significant portion of the speed of light. A regular black hole merger doesn’t do the trick - there’s not enough mass. Even a supermassive black hole merger isn’t detectable yet because these mergers seem to happen too slowly. This is why all the detections so far have been intermediate-mass black holes with dozens of times the mass of our Sun. And we can only detect them at the moment that they’re merging together, when they’re generating the most intense gravitational waves. If we can boost the sensitivity of our gravitational wave detectors, we should be able to spot mergers of less and more massive black holes. But merging isn’t the only thing they do. Black holes are born when stars with many more times the mass of our Sun collapse in on themselves and explode as supernovae. Some stars, we’ve now learned just implode as black holes, never generating the supernovae, so this process happens entirely hidden from us. Is there a singularity at the center of a black hole event horizon, or is there something there, some kind of object smaller than a neutron star, but bigger than an infinitely small point? As black holes merge together, we could see beyond the event horizon with gravitational waves, mapping out the invisible region within to get a sense of what’s going on down there. We want to know about even less massive objects like neutron stars, which can also form from a supernova explosion. These neutron stars can orbit one another and merge generating some of the most powerful explosions in the Universe: gamma ray bursts. But do neutron stars have surface features? Different densities? Could we detect a wobble in the gravitational waves in the last moments before a merger?

Host: Edo Berger Speaker: Brian Metzger The discovery of coalescing binary black holes by Advanced LIGO heralds the birth of a new field of research: gravitational wave (GW) astronomy. Coalescing neutron star (NS) binaries are among the new GW sources expected over the next few years. Maximizing the knowledge gained from this discovery will require identifying a coincident electromagnetic counterpart. One promising counterpart is an optical/IR flare, powered by the radioactive decay of neutron-rich elements synthesized in the merger ejecta (a so-called `kilonova'). Beyond providing a beacon to the GW chirp, kilonovae probe one of the dominant astrophysics sites for creating the heaviest elements in the Universe via rapid neutron capture (r-process) nucleosynthesis. I will describe how the lifetime of the hypermassive NS created during a NS-NS merger impacts the light curves and color of kilonovae, and how this affects the ongoing strategy of LIGO electromagnetic follow-up. A small fraction of short gamma-ray bursts are accompanied by long-lived X-ray emission, which may suggest that some mergers result in the formation of long-lived - or even indefinitely stable - NS remnants. If this association is confirmed, this would place stringent constraints on the equation of state of nuclear density matter.

A billion years ago, two black holes collided and merged, sending powerful ripples across the fabric of space-time. In 2015 those gravitational waves reached Earth and tickled the detectors of the Laser Interferometer Gravitational-Wave Observatory (LIGO). This first-ever detection of gravitational waves confirmed a long-standing prediction of Einstein's general relativity. It also was the culmination of a decades-long effort. Learn about the technical challenges of LIGO and the significance of this momentous event from one of the field's great pioneers, Rainer Weiss. Original music by Mark C.
