So buckle up and prepare for liftoff as we embark on this cosmic journey together.
Highlights:
- Record-Setting Black Hole Jets: In a groundbreaking discovery, astronomers have detected the largest known jets of energy shooting from a supermassive black hole. These colossal beams extend an astonishing 23 million light years from end to end, dwarfing our entire Milky Way galaxy. The black hole responsible for this cosmic spectacle is located in a galaxy about 7.5 billion light years from Earth. These jets, nicknamed Porphyrion, are made up of subatomic particles and magnetic fields, all moving at nearly the speed of light. This discovery provides valuable insights into how black holes influence their surroundings on a truly enormous scale.
- Rocket Lab Launch Abort: Rocket Lab experienced a last-second abort during their latest mission attempt. The company's Electron Rocket was poised to lift off from New Zealand carrying five Internet of Things satellites for the French company Kinéis. However, as the countdown reached zero and the first stage engines ignited, they immediately shut down, resulting in a launch abort. Rocket Lab's team is now assessing options for the next launch attempt within their 14-day launch window.
- Honoring NASA's Hidden Figures: In a moving ceremony at the US Capitol, four trailblazing women of NASA were honored with Congressional Gold Medals for their groundbreaking contributions to space exploration. Kathryn Johnson, Dorothy Vaughn, Mary Jackson, and Christine Darden, the hidden figures behind America's space race success, were finally given their well-deserved recognition. This ceremony not only celebrated these four women but also acknowledged the countless others who worked behind the scenes at NASA performing critical calculations before the advent of electronic computers.
- Ancient Earth with Rings: A new study suggests that our planet may have once sported a ring system similar to Saturn's about 466 million years ago. Researchers believe that Earth may have captured and destroyed a passing asteroid, creating a debris ring that lasted for tens of millions of years. This ring could have had a major impact on Earth's climate, potentially contributing to the Hernantean Ice Age, the coldest period Earth has experienced in the past 500 million years.
- Space Lasers for Planetary Defense: A recent study has explored the idea of deploying laser arrays in space for deflecting potentially hazardous asteroids. The concept, known as Directed Energy Systems for Targeting of Asteroids and Exploration (DE-STAR), involves creating a modular array of lasers powered by solar cells. These space-based lasers could heat the surface of incoming asteroids to about 3000 Kelvin, hot enough to alter their course. While no one is building a DE-STAR array just yet, it's crucial to start thinking about the implications and potential uses of such technology.

Speaker 1: For liftoff as we embark on this cosmic journey together,
Speaker 1: Let's dive into the fascinating world of space science and
Speaker 1: exploration on this episode of Astronomy Daily. In a groundbreaking discovery,
Speaker 1: astronomers have detected the largest known jets of energy shooting
Speaker 1: from a super massive black hole. These colossal beams extend
Speaker 1: an astonishing twenty three million light years from end to end,
Speaker 1: dwarfing our in higher Milky Way galaxy. The black hole
Speaker 1: responsible for this cosmic spectacle is located in a galaxy
Speaker 1: about seven point five billion light years from Earth. To
Speaker 1: put that in perspective, we're observing an event that occurred
Speaker 1: when the universe was less than.
Speaker 2: Half its current age.
Speaker 1: These jets, nicknamed Porphyrion after a giant from Greek mythology,
Speaker 1: are truly massive. They're about thirty percent longer than the
Speaker 1: previous record holder, making them the most extensive structures of
Speaker 1: their kind ever observed.
Speaker 2: But what exactly are these jets.
Speaker 1: They're made up of subatomic particles electrons and positrons, along
Speaker 1: with magnetic fields, all moving at nearly the speed of light.
Speaker 1: These particles are ejected from the area around the black
Speaker 1: hole as it devours nearby matter like gas, dust, and
Speaker 1: even entire stars. The energy output of these jets is
Speaker 1: mind boggling. Scientists estimate its equivalent to the energy released
Speaker 1: by trillions of stars like our Sun, or the amount
Speaker 1: produced when entire galaxy clusters collide. This discovery isn't just
Speaker 1: about breaking records, though, it provides valuable insights into how
Speaker 1: black holes influence their surroundings on a truly enormous scale.
Speaker 1: These jets can heat up interstellar gas, potentially affecting star
Speaker 1: formation across vast regions of space. They might even play
Speaker 1: a role in distributing energy and magnetic fields throughout the
Speaker 1: cosmic web, the large scale structure of the universe. The
Speaker 1: observation was made possible by LOFAR, a network of radio
Speaker 1: antennas primarily based in the Netherlands. This cutting edge technology
Speaker 1: allows astronomers to peer deeper into the universe and uncover
Speaker 1: phenomena that push the boundaries of our understanding of cosmic processes.
Speaker 1: As we continue to explore the depths of space, discoveries
Speaker 1: like Porphyrion remind us of the immense power and influence
Speaker 1: of supermassive black holes in shaping our universe. In space
Speaker 1: launch news, rocket Lab experienced a last second abort during
Speaker 1: their latest mission attempt. The company's Electron rocket was poised
Speaker 1: to lift off from New Zealand carrying five Internet of
Speaker 1: Things satellites for the French company QNIE. However, as the
Speaker 1: countdown reached zero and the first stage engines ignited, they
Speaker 1: immediately shut down, resulting in a launch abort. Rocket Lab
Speaker 1: has named this mission Keyness Killed the radiot Star a
Speaker 1: playful nod to the payload and a classic song title.
Speaker 1: This would have been their second launch for Canais, following
Speaker 1: a successful five satellite deployment in June. The aboard occurred
Speaker 1: at the precise moment of the instantaneous launch window, leaving
Speaker 1: no opportunity for a same day retry. Rocket Lab's team
Speaker 1: is now assessing options for the next launch attempt within
Speaker 1: their fourteen day launch window. This mission is part of
Speaker 1: a larger contract between rocket Lab and Kineis, which aims
Speaker 1: to deploy a total of twenty five satellites using the Electron,
Speaker 1: a small but capable rocket standing at fifty nine feet tall.
Speaker 1: Despite this setback, rocket Lab maintains an impressive track record
Speaker 1: with fifty two orbital missions to date, including ten successful
Speaker 1: launches in twenty twenty four alone. Now a story about
Speaker 1: recognition that many would consider long overdue. In a moving
Speaker 1: ceremony at the US Capitol, four trailblazing women of NASA
Speaker 1: were honoured with Congressional Gold Medals for their groundbreaking contributions
Speaker 1: to space exploration. Catherine Johnson, Dorothy Vaughan, Mary Jackson, and
Speaker 1: Christine Darden. The hidden figures behind America's space race success
Speaker 1: were finally given their well deserved recognition. The event, held
Speaker 1: in Emancipation Hall, brought together lawmakers, NASA officials, and family
Speaker 1: members of these remarkable women. NASA Administrator Bill Nelson highlighted
Speaker 1: how their pioneering work laid the foundation for today's achievements
Speaker 1: in space. These African American mathematicians and engineers played crucial
Speaker 1: roles in NASA's early spaceflight programs, from calculating flight trajectories
Speaker 1: to becoming the agency's first black female supervisor and engineer.
Speaker 1: Their stories, largely unknown for decades, were brought to light
Speaker 1: by Margo Lee Shutterley's book Hidden Figures and the subsequent
Speaker 1: film adaptation. The ceremony not only celebrated these four women,
Speaker 1: but also acknowledged the countless others who worked behind the
Speaker 1: scenes at NASA performing critical calculations before the advent of
Speaker 1: electronic computers. This Congressional Gold Medal, one of the highest
Speaker 1: civilian honors in the United States, serves as a testament
Speaker 1: to their enduring legacy and the impact they've had on
Speaker 1: generations of scientists and engineers. It's a powerful reminder of
Speaker 1: the importance of diversity in scientific advancement, and a long
Speaker 1: overdue recognition of these hidden figures who helped shape America's
Speaker 1: space program. Now, let's turn our attention to a fascinating
Speaker 1: piece of research that's shaking up our understanding of Earth's
Speaker 1: ancient past. A new study suggests that our planet may
Speaker 1: have once sported a ring system similar to Saturn's about
Speaker 1: four hundred and sixty six million years ago. This isn't
Speaker 1: just idle speculation. It's based on some intriguing evidence from
Speaker 1: twenty one crater sites around the world.
Speaker 2: Here's the story.
Speaker 1: Researchers believe that Earth may have captured and destroyed a
Speaker 1: passing asteroid, creating a debris ring that lasted for tens
Speaker 1: of millions of years. This event potentially occurred during the
Speaker 1: Ordovician period, a time when our planet experienced a significant
Speaker 1: increase in asteroid impacts. The team, led by Andy Tompkins
Speaker 1: from Monash University used computer models to map out where
Speaker 1: these craters were when they first formed. Interestingly, all the
Speaker 1: craters were found within thirty degrees of the equator. This
Speaker 1: pattern is consistent with what we'd expect from a debris
Speaker 1: ring orbiting Earth, as such rings typically form above a
Speaker 1: planet's equator. Now, you might be wondering about the implications
Speaker 1: of such a ring system, while the researchers suggest it
Speaker 1: could have had a major impact on Earth's climate. Because
Speaker 1: Earth's axis is tilted relative to its orbit around the Sun,
Speaker 1: this ring would have cast a shadow over parts of
Speaker 1: our planet's surface. This could have contributed to global cooling,
Speaker 1: potentially playing a role in the Hernantean Ice Age, the
Speaker 1: coldest period Earth has experienced in the past five hundred
Speaker 1: million years. Of course, as with all groundbreaking research, more
Speaker 1: evidence is needed to confirm this hypothesis, but it's an
Speaker 1: exciting possibility that gives us a new perspective on Earth's
Speaker 1: dynamic history. Who knows what other surprises our planet might
Speaker 1: be hiding in its geological record. Now, let's talk about
Speaker 1: an intriguing concept that might sound like it's straight out
Speaker 1: of science fiction, using powerful lasers in space for planetary defense.
Speaker 1: A recent study has explored the idea of deploying laser
Speaker 1: arrays in space, primarily for deflecting potentially hazardous asteroids. The concept,
Speaker 1: known as DSTAR, which stands for Directed Energy Systems for
Speaker 1: Targeting of Asteroids and Exploration, involves creating a modular array
Speaker 1: of lasers powered by solar cells. These space based lasers
Speaker 1: could heat the surface of incoming asteroids to about three
Speaker 1: thousand kelvin, hot enough to melt or vaporize their constituents
Speaker 1: and alter their course. Additionally, such a system could potentially
Speaker 1: be used to propel spacecraft. However, with great power comes
Speaker 1: great responsibility. The destructive potential of these laser arrays raises
Speaker 1: concerns about their possible use as weapons. To address this,
Speaker 1: researchers suggest deploying them at safe distances from Earth, where
Speaker 1: they pose no threat to our planet. The size and
Speaker 1: power of the laser array would determine its safe minimum
Speaker 1: distance from Earth. Smaller arrays could pretend be positioned at
Speaker 1: lagrange points between the Earth and Sun, while larger, more
Speaker 1: powerful arrays would need to be placed much further out
Speaker 1: in the Solar System, possibly beyond the asteroid belt or
Speaker 1: even Jupiter's orbit. One challenge is balancing the laser's power
Speaker 1: with available solar energy, which decreases the further the array
Speaker 1: is from the Sun. Engineers would need to consider this
Speaker 1: trade off when designing and positioning these systems.
Speaker 2: While no one is building a.
Speaker 1: D star array just yet, it's crucial to start thinking
Speaker 1: about the implications and potential uses of such technology. As
Speaker 1: we continue to explore space and seek ways to protect
Speaker 1: our planet, concepts like space based lasers may become increasingly
Speaker 1: relevant in our discussions about planetary defense and space exploration.
Speaker 1: And that wraps up today's episode of Astronomy Daily. We've
Speaker 1: covered some truly fascinating developments in space science and exploration,
Speaker 1: from the record setting jets blasting out of a distant
Speaker 1: black hole to the potential for space lasers to protect
Speaker 1: our planet. The universe continues to amaze and challenge us.
Speaker 1: We also celebrated the long overdue recognition of the hidden
Speaker 1: figures who played such a crucial role in NASA's early achievements,
Speaker 1: and explored the intriguing possibility that Earth once had its
Speaker 1: own ring system. I'm Anna, and I've been your host
