'We're stepping away from Mother Earth to explore our solar system with todays #imageoftheweek!' European Space Agency - ESA's Mars Express spacecraft has discovered intriguing features on Mars known as "spiders" in the planet's southern polar region. 🕷️These spider-like formations are not actual spiders but dark spots formed when sunlight interacts with layers of carbon dioxide ice during the martian winter. As sunlight melts the ice, bursts of gas push dark material upward, creating spider-shaped patterns beneath the surface. The ExoMars Trace Gas Orbiter has also captured these patterns. 🛰️ This discovery highlights how Earth Observation isn't just about our own planet but extends to understanding others as well. 🔗https://bit.ly/44r7QbF.

The discovery of planets beyond our solar system, known as exoplanets 🌌, has greatly expanded our understanding of the universe 🌠. While earlier missions like Kepler have identified thousands of these distant worlds 🌍, determining their masses remains a significant challenge. Measuring a planet's mass is crucial as it reveals much about its composition, atmosphere, and potential to support life 🌱. However, obtaining accurate mass measurements requires advanced techniques and sensitive instruments 🔬. One effective method is observing the ‘wobble’ of a star 🌟 caused by the gravitational pull of an orbiting planet, which shifts the star's light spectrum. This phenomenon, known as the radial velocity method, provides essential data for understanding these distant worlds 🪐.   New data from the Transiting Exoplanet Survey Satellite (TESS) 🚀 and the W.M. Keck Observatory 🔭 has been used to make significant strides in this area. This research, part of the TESS-Keck Survey (TKS), has produced the largest and most uniform mass catalogue of exoplanets to date 📊. By analysing over 9,000 radial velocity measurements, the team determined the masses of 126 exoplanets and discovered 15 new ones 🌠. This comprehensive dataset allows scientists to estimate the densities and compositions of these planets, providing valuable insights into their nature. Notably, the study identified two particularly intriguing planets: TOI-1824 b, a superdense sub-Neptune 🌑, and TOI-1798 c, an extreme super-Earth 🌍, which is so close to its host star that it makes one orbit in less than 12 hours. These findings contribute to a deeper understanding of planetary diversity and evolution, highlighting the unique characteristics of our own solar system 🌞.   Here's my poetic interpretation 🖋️✨:   https://lnkd.in/e5hRK9_7   #scicomm 🗣️ #scipoem 🖋️ #sciart 🎨 #sciencecommunication 📢

Exploring the Missing Link in Planetary Science: TOI-2447 b Exciting new research led by The University of Warwick is shedding light on the connection between the hot, Jupiter-sized exoplanets we often find close to their stars, and the cold giants of our own Solar System, like Saturn. TOI-2447 b, is a rare exoplanet about the size of Saturn, orbiting a Sun-like star 490 lightyears away. Unlike the majority of known exoplanets, TOI-2447 b sits much farther from its star, making it cooler—around 140°C—compared to the high temperatures of many exoplanets that are typically over 1000°C. This planet’s unique position in its star system provides a crucial missing piece to the puzzle of planetary formation. TOI-2447 b orbits its star every 69 days, a contrast to the 29 years it takes Saturn to orbit the Sun. Its intermediate properties make it a fascinating case for testing theories about how planets form and evolve. The study also hints at the presence of even more distant and cooler planets in this system—potentially including rocky planets that could be conducive to life. Dr. Samuel Gill from The University of Warwick explains, "These planets bridge the gap between the well-known hot Jupiters and our Solar System's gas giants, helping us to understand a wider variety of planetary systems." As we continue to investigate with tools like the James Webb Space Telescope (JWST), we’re on the cusp of uncovering even more about the origins and nature of these distant worlds. #Exoplanets #SpaceResearch #Astronomy #PlanetFormation #ScienceInnovation #TESS #JWST Oliver Walmsley Penny Triantafillou Catherine Louch Anthony Avery Rachael Kirwan

Comet Pons-Brooks' Ion Tail Image Credit & License: James Peirce Explanation: Comet Pons-Brooks has quite a tail to tell. First discovered in 1385, this erupting dirty snowball loops back into our inner Solar System every 71 years and, this time, is starting to put on a show for deep camera exposures. In the featured picture, the light blue stream is the ion tail which consists of charged molecules pushed away from the comet's nucleus by the solar wind. The ion tail, shaped by the Sun's wind and the comet's core's rotation, always points away from the Sun. Comet 12P/Pons–Brooks is now visible with binoculars in the early evening sky toward the northwest, moving perceptibly from night to night. The frequently flaring comet is expected to continue to brighten, on the average, and may even become visible with the unaided eye -- during the day -- to those in the path of totality of the coming solar eclipse on April 8. #PhoenixDelivers #nasa

The Enigmatic World of Rogue Planets Imagine a planet drifting through the vast expanse of space, untethered to any star. These mysterious celestial bodies, known as rogue planets, offer a glimpse into the most extreme and awe-inspiring aspects of our universe. Rogue planets challenge our understanding of planetary formation. Traditionally, we believe planets form around stars, held in their orbits by gravity. However, rogue planets either formed in isolation or were ejected from their original systems. Studying these cosmic vagabonds helps scientists piece together the dynamic processes that shape our galaxy. But beyond science, rogue planets capture the imagination. They evoke a sense of wonder and mystery—worlds that have no sun, yet still exist. Could they harbor life? Do they experience the same geological processes as Earth? These are the questions that push us to explore further. Detecting rogue planets is no easy feat. They don't emit light like stars, and they don’t have the reflective glow of planets orbiting stars. Enter gravitational microlensing—a phenomenon predicted by Einstein’s theory of relativity. This technique works much like a lens in your camera. When a rogue planet passes between Earth and a distant star, its gravity bends the light from that star, causing it to briefly brighten. This “lensing” effect can be detected by telescopes here on Earth, allowing astronomers to infer the presence of the planet. Gravitational microlensing has several advantages: No light required: Unlike other methods, microlensing doesn’t rely on the rogue planet emitting or reflecting light. Precise detection: The brightening of the star’s light provides precise information about the planet’s mass and distance. This technology opens the door to finding many more rogue planets and other cosmic apparitions hidden from view. The study of rogue planets is still in its infancy, but the potential for discovery is immense. Scientists believe there may be as many rogue planets as there are stars in our galaxy—a staggering thought. So next time you look up at the night sky, consider that there may be countless planets drifting unseen, waiting to be discovered. Rogue planets remind us that the universe is far more mysterious and complex than we ever imagined. Check out my newsletter for an in-depth analysis.

Earth-Sized Planet Found Next Door! Hold onto your spacesuits! Scientists just discovered an Earth-sized planet orbiting a tiny red dwarf star only 55 light-years away! That's practically cosmic walking distance. This little world, called SPECULOOS-3 b, is a hot one though. It races around its star in just 17 hours, meaning one side is always bathed in sunlight while the other is stuck in eternal night. Imagine never-ending sunburns on one side and cryotherapy on the other! Here's the coolest part (pun intended!): This star is a super long-lifer. While our Sun will burn out in a measly 10 billion years, these red dwarfs can chill for 100 billion years or more! That's plenty of time for life to maybe, just maybe, get cookin'. Scientists are itching to learn more about SPECULOOS-3 b with the James Webb Space Telescope. Will it have an atmosphere? What kind of rocks are on its surface? 🪐 Could it be a distant cousin of Earth? Follow this page to Stay tuned, space fans, the future of exoplanet exploration is looking bright! ✨ Learn more - https://lnkd.in/gZX5V7mP #SpaceNews #EarthSizePlanet #RedDwarf #SPECULOOS #JamesWebb
