Comets

26 cards. Each one is a 40-second story with a five-minute read behind it.

  1. The cosmic leftovers that may have delivered life to EarthOften called "dirty snowballs," comets are more than just celestial spectacles. These icy relics from the dawn of our solar system might hold the secret ingredients for existence …
  2. Surviving a 75-year journey on a ball of iceWhat would it actually be like to live on a comet? This video explores the hypothetical journey of hitching a ride on Halley's Comet, examining the extreme conditions of the solar…
  3. The cosmic forces shaping reality in the world of OooExplore the lore of the Catalyst Comets, some of the most powerful forces in the Adventure Time universe. This video breaks down their influence on reality, reincarnation, and the…
  4. Cosmic snowballs that preserve a chemical record of our solar system's birthComets are more than just beautiful streaks across the night sky; they are time capsules. Because they formed in the freezing outer reaches of the early solar nebula, these object…
  5. A high-speed flyby reveals the hidden mechanics of comet activityNASA's EPOXI spacecraft recently completed a flyby of comet Hartley 2, capturing critical data on how these celestial bodies behave. This mission provides a rare look at the volum…
  6. A cosmic rendezvous scheduled for Valentine's DayOn February 14, the Stardust-NExT mission will approach comet Tempel 1. This mission offers a rare chance to observe how a comet's surface evolves after orbiting the sun.
  7. The subjective science of what makes a comet 'great'Not every comet that lights up the night sky earns the title of 'great.' While astronomers track orbits with precision, the distinction of a great comet is actually a societal lab…
  8. The massive, coal-black behemoth lurking in our solar systemAstronomers have identified a comet nucleus so large it dwarfs the state of Rhode Island. Traveling at 22,000 miles per hour, this icy giant is much larger and heavier than typica…
  9. Comets possess two distinct tails, each driven by different solar forcesA comet's tail is not a single structure but a dual phenomenon. One is a river of dust reflecting light, while the other is a plasma stream of ionized gas. These two tails react d…
  10. Comet ISON may have shattered during a major heating eventAstronomers believe there is a more than 90% probability that Comet ISON broke apart on Thanksgiving Day. As the comet approached the sun, intense heat may have destroyed it, leav…
  11. The spacecraft that survived a cosmic sandblasting to reveal a dark secretIn March 1986, the Giotto probe flew within 600 km of Halley's comet. It narrowly escaped destruction while enduring a violent barrage of particles, ultimately capturing the first…
  12. How scientists chose a safe spot on a giant cosmic duckLanding a spacecraft on a comet is a high-stakes balancing act. Engineers had to weigh scientific potential against the risk of landing on a surface that was becoming increasingly…
  13. After 31 months of deep space slumber, Rosetta wakes to chase a cometLaunched in 2004, the Rosetta spacecraft spent years cruising through the cold void beyond Jupiter. On January 20, 2014, a pre-programmed alarm clock finally stirred the probe fro…
  14. Did Comets Seed Life? Rosetta's Journey to Answer Cosmic QuestionsThe European Space Agency's Rosetta mission orbited comet 67P/Churyumov-Gerasimenko to investigate fundamental questions: Did water arrive on Earth from comets, and were comets re…
  15. Rosetta's daring descent to within 6 km of a comet's surfaceOn 14 February 2015, the Rosetta spacecraft executed a high-stakes maneuver, swooping just 6 km above Comet 67P/Churyumov-Gerasimenko. This transition from orbiting to flyby traje…
  16. How Rosetta and Philae unlocked the secrets of a distant cometThis video reviews the historic Rosetta mission, from its 2004 launch to the unprecedented landing of the Philae lander on comet 67P/Churyumov-Gerasimenko.
  17. How a single spacecraft transformed our understanding of a celestial wandererIn August 2014, the Rosetta orbiter achieved a historic first by entering orbit around comet 67P/Churyumov-Gerasimenko. This mission was not just a flyby; it was a sophisticated, …
  18. Philae's silent legacy on the frozen surface of Comet 67PAfter a historic landing on a comet hundreds of millions of miles from Earth, the Philae lander has gone silent. Deprived of sufficient sunlight to power its batteries, the craft …
  19. Why comets are far from the dirty snowballs we once imaginedFor decades, scientists viewed comets as mere dirty snowballs. However, the European Space Agency's Rosetta mission has fundamentally rewritten this narrative. By orbiting and lan…
  20. How Rosetta is breaking records while orbiting comet 67PThis film explores the final months of the Rosetta mission as it performs breathtaking manoeuvres near the surface of comet 67P/Churyumov-Gerasimenko to uncover the chemical build…
  21. How Rosetta navigated the unpredictable environment of Comet 67PThis animation visualises the two-year journey of the Rosetta spacecraft around Comet 67P/Churyumov–Gerasimenko, detailing the complex maneuvers required to map the surface and de…
  22. The final descent of the Rosetta mission to comet 67PAs the Rosetta spacecraft approaches the end of its mission, it is capturing unprecedentedly close views of the comet's surface, documenting a landscape in constant motion.
  23. How the Rosetta spacecraft will conclude its historic mission on Comet 67P/C-GWith the Rosetta mission nearing its conclusion, specialists are debating the scheduled landing on Comet 67P/C-G and the anticipated scientific findings from this epic end.
  24. Why the Rosetta mission's scientific legacy is still unfolding years laterAlthough the Rosetta mission officially ended its operations in September 2016, the data continues to yield new insights. Discover how recent workshops are shaping the future of c…
  25. The final views from Rosetta before its descent onto Comet 67PWitness the high-resolution images captured by the OSIRIS camera during the final hours of the Rosetta mission. This compilation shows the spacecraft scanning an ancient pit just …
  26. In 2014, humanity achieved the first-ever landing on a comet's surface.The Rosetta mission marked a milestone in space exploration by successfully landing the Philae probe on Comet 67P/Churyumov-Gerasimenko. This video revisits the highlights of a de…
