A previous version of this video mislabeled the orbit of Saturn as the orbit of Jupiter. This new NASA animation highlights the “super” in supermassive black holes. These monsters lurk in the centers of most big galaxies, including our own Milky Way, and contain between 100,000 and tens of billions of times more mass than our Sun. Any light crossing the event horizon – the black hole’s point of no return – becomes trapped forever, and any light passing close to it is redirected by the black hole’s intense gravity. Together, these effects produce a “shadow” about twice the size of the black hole’s actual event horizon. The animation shows 10 supersized black holes that occupy center stage in their host galaxies, including the Milky Way and M87, scaled by the sizes of their shadows. Starting near the Sun, the camera steadily pulls back to compare ever-larger black holes to different structures in our solar system. First up is 1601+3113, a dwarf galaxy hosting a black hole packed with the mass of 100,000 Suns. The matter is so compressed that even the black hole’s shadow is smaller than our Sun. The black hole at the heart of our own galaxy, called Sagittarius A* (pronounced ay-star), boasts the weight of 4.3 million Suns based on long-term tracking of stars in orbit around it. It’s shadow diameter spans about half that of Mercury’s orbit in our solar system. The animation shows two monster black holes in the galaxy known as NGC 7727. Located about 1,600 light-years apart, one weighs 6 million solar masses and the other more than 150 million Suns. Astronomers say the pair will merge within the next 250 million years. At the animation’s larger scale lies M87’s black hole, now with a updated mass of 5.4 billion Suns. Its shadow is so big that even a beam of light – traveling at 670 million mph (1 billion kph) – would take about two and a half days to cross it. The movie ends with TON 618, one of a handful of extremely distant and massive black holes for which astronomers have direct measurements. This behemoth contains more than 60 billion solar masses, and it boasts a shadow so large that a beam of light would take weeks to traverse it.

Gravitational waves, imperceptible undulations in the very structure of space-time, arise from the most tumultuous and high-energy occurrences in the cosmos. These phenomena encompass the collision of black holes, the implosion of massive stellar cores, the fusion of neutron stars or white dwarf stars, the irregular gyrations of non-spherical neutron stars, and conceivably, the echoes of gravitational radiation dating back to the inception of the universe. In the following video, Dr. Padi Boyd elucidates the concept of gravitational waves and underscores the pivotal role played by the Hubble Space Telescope in unraveling the enigmatic facets of our universe.

Each time it approaches the black hole, the star swells and sheds material, like a celestial flirtation with destiny. And yet, it somehow manages to escape the clutches of its gravitational captor, only to repeat the mesmerizing waltz over and over again. This celestial ballet unfolds thanks to Swift's X-ray Telescope (XRT), which captured Swift J0230's cosmic performance for the first time on June 22, 2022. Since then, this enigmatic star has lit up the night sky with a series of dazzling outbursts, occurring roughly every few weeks, much to the delight of eager astronomers. Intriguingly, Swift J0230 appears to be a repeating tidal disruption event, where the star's fate hangs in the balance with each encounter, all while orbiting a black hole of mind-boggling proportions, over 200,000 times the mass of our Sun. It's estimated that with each pass, the star sheds a staggering three Earth masses of material, a cosmic spectacle that pushes the boundaries of our understanding of the cosmos. This celestial revelation, Swift J0230, not only captivates our imaginations but also serves as a bridge to unlock the secrets of other suspected repeating disruptions. It offers a cosmic canvas on which scientists can paint the intricate interplay between different types of stars and black holes, unveiling a mesmerizing tapestry of behaviors that continue to challenge our cosmic comprehension. But how did we uncover this cosmic gem? Thanks to a cutting-edge tool known as the Swift X-ray Transient Detector, which automates the search for such celestial wonders. After scanning a portion of the sky, the instrument transmits its findings to Earth, where a sophisticated program compares them to previous snapshots. When the X-ray sky shows signs of change, scientists receive a cosmic alert, allowing them to swiftly coordinate additional observations and dive deeper into the mysteries of the universe. In the grand cosmic theater, where stars twirl and black holes beckon, Swift J0230's captivating performance reminds us that the universe is a stage where the most extraordinary stories unfold, waiting to be discovered by those who dare to look beyond the stars.
