Jupiter is not just the oldest planet orbiting the sun—it’s also the largest. So when the young gas giant went on a rampage through the inner solar system, it shaped the fate of everything in its path. Speeding towards the Sun, Jupiter’s massive gravitational force hurled debris into interstellar space, stunting the growth of would-be planets. Earth might have been doomed had Saturn not pulled Jupiter back. Today, Jupiter resides in the outer solar system, where its gravity bends the paths of asteroids and stokes volcanic activity on its moon Io. But it could one day wreak havoc again. \u003cb\u003e(Premiered July 31,

exotic objects in the universe. They’re also the most powerful, with gravity so strong it can trap light. And they’re destructive, swallowing entire planets, even giant stars. Anything that falls into them vanishes…gone forever. Now, astrophysicists are realizing that black holes may be essential to how our universe evolved—their influence possibly leading to life on Earth and, ultimately, us. In this two-hour special, astrophysicist and author Janna Levin takes viewers on a journey to the frontiers of black hole science. Along the way, we meet leading astronomers and physicists on the verge of finding new answers to provocative questions about these shadowy monsters: Where do they come from? What’s inside? What happens if you fall into one? And what can they tell us about the nature of space, time, and gravity?

Now, after highly publicized sightings of unidentified objects by Navy pilots, UFOs are moving out of the shadows and into the light, as NASA pledges to study them scientifically. So what does science have to say? Though some are identified as balloons or drones, weather phenomena, or optical illusions, others remain mysterious. Could they be the result of secret new technology developed by other governments – or our own? And what would it take for alien engineers to traverse vast distances to send probes or visit Earth from other solar systems? Explore the evidence, as astrophysicists and engineers use new technologies to investigate the strangest objects in our skies. \u003cb\u003e(Premiering January 22, 2025 at 9 pm on PBS)\u003c/b\u003e\u003c/p\u003e\n\u003cp data-block-key=\"2ipvq\"\u003e\u003cb\u003eWhat Are U.F.O.s?\u003c/b\u003e\u003c/p\u003e\u003cp data-block-key=\"d3boj\"\u003ePublished: January 22, 2025\u003c/p\u003e\u003cp data-block-key=\"850q5\"\u003e\u003cb\u003eNAVY PILOT #1:\u003c/b\u003e Looking at that thing.

That might actually be true in this case, though, it\u0026#x27;s this one-off event, and it might\u0026#x27;ve been that an object hit Mars, and Phobos is the result of that impact collision between those objects, and that\u0026#x27;s what we\u0026#x27;re seeing.\u003c/p\u003e\u003cp data-block-key=\"dkvdq\"\u003e\u003cb\u003eNarrator:\u003c/b\u003e Phobos may not be a captured asteroid at all, but formed from debris thrown into orbit after a massive asteroid impact. However, this still doesn\u0026#x27;t explain why it\u0026#x27;s covered in grooves. Phobos is about 3,700 miles from Mars\u0026#x27;s surface, and every a hundred years moves closer by about six feet, and as it does, the tidal forces caused by Mars gravity becomes stronger.\u003c/p\u003e\u003cp data-block-key=\"1i5th\"\u003e\u003cb\u003eSpeaker 1:\u003c/b\u003e So just like the moon pulls on the earth, dragging the oceans and causing the tide, Mars pulls on Phobos causing tides as well. So as you can see behind me right now, the tide is coming in as the moon is pulling on the water on the Earth. The same process happens on Phobos due to Mars, except on Phobos it\u0026#x27;s sand and rock that\u0026#x27;s moving instead of water.\u003c/p\u003e\u003cp data-block-key=\"6oip\"\u003e\u003cb\u003eNarrator:\u003c/b\u003e Those tidal forces are pulling Phobos apart, and with every orbit, the grooves widen and deepen. Eventually, Phobos will drift so close, Mars\u0026#x27;s gravity will destroy it. As Phobos breaks apart, most of the debris will fall to the surface of Mars, but the rest will remain in close orbit, spreading out to encircle the entire planet, giving Mars a wispy

Now, after highly publicized sightings of unidentified objects by Navy pilots, UFOs are moving out of the shadows and into the light, as NASA pledges to study them scientifically. So what does science have to say? Though some are identified as balloons or drones, weather phenomena, or optical illusions, others remain mysterious. Could they be the result of secret new technology developed by other governments – or our own? And what would it take for alien engineers to traverse vast distances to send probes or visit Earth from other solar systems? Explore the evidence, as astrophysicists and engineers use new technologies to investigate the strangest objects in our skies. \u003cb\u003e(Premiering January 22, 2025 at 9 pm on PBS)\u003c/b\u003e\u003c/p\u003e\n\u003cp data-block-key=\"2ipvq\"\u003e\u003cb\u003eWhat Are U.F.O.s?\u003c/b\u003e\u003c/p\u003e\u003cp data-block-key=\"d3boj\"\u003ePublished: January 22, 2025\u003c/p\u003e\u003cp data-block-key=\"850q5\"\u003e\u003cb\u003eNAVY PILOT #1:\u003c/b\u003e Looking at that thing.

However, this still doesn\u0026#x27;t explain why it\u0026#x27;s covered in grooves. Phobos is about 3,700 miles from Mars\u0026#x27;s surface, and every a hundred years moves closer by about six feet, and as it does, the tidal forces caused by Mars gravity becomes stronger.\u003c/p\u003e\u003cp data-block-key=\"1i5th\"\u003e\u003cb\u003eSpeaker 1:\u003c/b\u003e So just like the moon pulls on the earth, dragging the oceans and causing the tide, Mars pulls on Phobos causing tides as well. So as you can see behind me right now, the tide is coming in as the moon is pulling on the water on the Earth. The same process happens on Phobos due to Mars, except on Phobos it\u0026#x27;s sand and rock that\u0026#x27;s moving instead of water.\u003c/p\u003e\u003cp data-block-key=\"6oip\"\u003e\u003cb\u003eNarrator:\u003c/b\u003e Those tidal forces are pulling Phobos apart, and with every orbit, the grooves widen and deepen.

And you can take a look at the before and after pictures, and you can see that it looks like the solar panels have just been wiped clean.

So a mission expected to last just a few months was extended again and again and again. But the cleaning power of the dust devils doesn\u0026#x27;t just work on rovers. As they travel, these huge vortices suck up dust from Mars\u0026#x27;s surface, exposing the darker bedrock beneath, leaving trails so large, you can see them clearly from space.

exotic objects in the universe. They’re also the most powerful, with gravity so strong it can trap light. And they’re destructive, swallowing entire planets, even giant stars. Anything that falls into them vanishes…gone forever. Now, astrophysicists are realizing that black holes may be essential to how our universe evolved—their influence possibly leading to life on Earth and, ultimately, us. In this two-hour special, astrophysicist and author Janna Levin takes viewers on a journey to the frontiers of black hole science. Along the way, we meet leading astronomers and physicists on the verge of finding new answers to provocative questions about these shadowy monsters: Where do they come from? What’s inside? What happens if you fall into one? And what can they tell us about the nature of space, time, and gravity?
