<POSSIBILITY OF A THICK ATMOSPHERE ON TRAPPIST 1-b The first James Webb Space Telescope/MIRI photometric observations of TRAPPIST-1 b allowed for the detection of the thermal emission of the planet at 15 μm, suggesting that the planet could be a bare rock with a zero albedo and no redistribution of heat. These observations at 15 μm were acquired as part of Guaranteed Time Observer time that included a twin programme at 12.8 μm to obtain measurements inside and outside the CO2 absorption band. Reaearchers (including such from EAI institutions) present five new occultations of TRAPPIST-1 b observed with MIRI in an additional photometric band at 12.8 μm. The authors perform a global fit of the ten eclipses and derive a planet-to-star flux ratio and 1σ error of 452 ± 86 ppm and 775 ± 90 ppm at 12.8 μm and 15 μm, respectively. They find that two main scenarios emerge. An airless planet model with an unweathered (fresh) ultramafic surface, that could be indicative of relatively recent geological processes, fits the data well. Alternatively, a thick, pure-CO2 atmosphere with photochemical hazes that create a temperature inversion and result in the CO2 feature being seen in emission also works, although with some caveats. Our results highlight the challenges in accurately determining a planet’s atmospheric or surface nature solely from broadband filter measurements of its emission, but also point towards two very interesting scenarios that will be further investigated with the forthcoming phase curve of TRAPPIST-1 b. The findings have been published in Nature Astronomy: https://lnkd.in/de2X-sv8

I love how embracing diverse perspectives can unlock hidden wonders, much like the Mirascope reveals a magical floating image ✨ Have you ever faced a situation where you had to shift your viewpoint to have a better understanding of things! The Mirascope is a fascinating optical device that creates the illusion of a floating 3D image using curved parabolic mirrors. It demonstrates how our perception can be manipulated through clever use of reflection and perspective. And I can't help but relate this to the broader importance of perspective in our daily life and work. In physics, perspective is crucial for understanding phenomena like relativity and quantum mechanics, where the observer's frame of reference impacts measurements and interpretations. The Overview Effect experienced by astronauts viewing Earth from space exemplifies how a shift in physical perspective can profoundly alter one's worldview. More philosophically, considering different perspectives enhances empathy, critical thinking, and our grasp of complex issues. Just as the Mirascope tricks our eyes, our default perspectives can limit our understanding. Actively seeking new vantage points - whether literal or metaphorical - expands our comprehension of reality and our place within it.

Astronomy Picture of the Day (APOD) [458089531_968920421937818_1815480661714083805_n.jpg] A Triangular Prominence Hovers Over the Sun (APOD: 2024 Sep 02) Image Credit & Copyright: Andrea Vanoni https://lnkd.in/dAZqvKpZ Explanation: Why is there a triangle hovering over the Sun? Although the shape is unusual, the type of structure is not: it is part of an evolving solar prominence. Looping magnetic fields on the Sun channel the flow of energetic particles, sometimes holding glowing gaseous structures aloft for months. A prominence glows brightly because it contains particularly hot, dense, or opaque solar plasma. The surprising triangular structure occurred last week. Larger than our Earth, the iconic prominence was imaged by several solar photographers and documented by NASA's Solar Dynamic Observatory to form and violently dissipate in about a day. The featured image was captured in a color of red light emitted strongly by hydrogen. Below, solar fibrils carpet the Sun's chromosphere, while the background sky is so faint in comparison that no stars are visible. Our Sun's surface has been quite active this year. https://lnkd.in/dNh2wmwu #APOD

🔭 Unlocking the Universe: An Introduction to Telescopes and Optical Design 🌌 Have you ever wondered how we’re able to peer into the distant corners of the universe? 🌠 The answer lies in telescopes – an incredible marriage of science, engineering, and optics. Telescopes are more than just magnifying tools; they are windows into the cosmos, allowing us to study stars, planets, galaxies, and more.

Giant Magellan Telescope Enclosure Ready for Construction The Giant Magellan Telescope's enclosure, one of the largest mechanized buildings ever constructed, passed its final design review and is now ready for construction in Chile. The Giant Magellan Telescope and IDOM announced today that the dome of the telescope, intended to be one of the world's largest astronomical facilities, has passed the final design review stage and is now ready to be built in Chile. The design approval marks an important milestone for the telescope, whose construction is 40 % complete, with a view to starting operations in the early 2030s.   A team of 10 international experts validated IDOM's design of the Giant Magellan Telescope dome as a technical and engineering feat. The 65-metre-high, 5,000-tonne dome will rotate in four minutes and will have 46-metre windows. This design will protect the 25.4-metre telescope, which will observe objects more than a billion light years away. Construction is progressing with the seventh primary mirror, the 39-metre mount and the first adaptive secondary mirror, among other technologies, providing 10 times the resolution of Hubble.   With the dome design completed, the Giant Magellan Telescope is now preparing for an international search process to select the company that will make its mark on the future of astronomy with the construction of the dome. #GMT #GiantMagellanTelescope #Telescope #Chile #Astronomy #Construction

TIME DILATION #snsinstution #designthinkers #designerthinking Time dilation is a fundamental concept in physics, particularly in Einstein's theory of relativity. It suggests that time is relative and passes at different rates for different observers, depending on their relative motion or positions in a gravitational field ¹. *What is Time Dilation?* Time dilation occurs when an object moves at high speeds or is placed in a strong gravitational field. This causes time to pass more slowly for the object relative to a stationary observer. For instance, if you were to travel at 95% of the speed of light to a planet 9.5 light-years away, you would experience time passing at a different rate than someone who stayed on Earth ¹. *Types of Time Dilation* There are two types of time dilation: - *Special Relativistic Time Dilation*: This occurs when an object moves at a significant fraction of the speed of light relative to an observer, causing time to slow down for the moving object from the observer's perspective. - *General Relativistic Time Dilation*: This occurs in the presence of a gravitational field, where time passes more slowly near a massive object due to its stronger gravitational pull ¹. *Time Dilation Formula* The time dilation formula is given by: T = T0 / √(1 - v^2/c^2) where T is the time observed, T0 is the time observed at rest, v is the velocity of the object, and c is the speed of light in a vacuum ². *Examples and Implications* Time dilation has been confirmed through various experiments and has significant implications for our understanding of time and space. For example, GPS systems must account for time dilation to maintain accurate positioning, and astronauts traveling to distant stars would experience time passing at a different rate than those on Earth ¹.

It's time to build. "Whenever we build a new, more powerful telescope, we discover new and strange and wonderful things. Things that have been there all along, but invisible to us with our puny eyes and primitive technology. There’s an old joke that the quality of the astronomer is proportional to the size of the telescope.

Photo-chemistry in Exoplanetary Atmosphere. ---------------------------------------------------------------------- The James Webb Space Telescope is a beautiful instrument which has discovered so many new things in its early observation programs. One of the remarkable discoveries has been the detection of Sulphur Dioxide in the atmosphere of the exoplanet WASP-39 b. With its high resolving power as compared to other space telescopes and a broad wavelength coverage, several instruments on the JWST has detected the presence of SO2 in WASP-39 b's atmosphere. With the range of temperature that prevails in the exoplanet's atmosphere. It is inferred that the spectral feature at around 4.05 micrometer belongs to SO2 and is a product of photochemical reactions. Below you can see the transmission spectrum observed by JWST NIRSpec PRISM instrument and a corresponding model spectrum fit. This model was fitted by using a retrieval code which I have developed during the last couple of months. It is seen that models assuming clouds best describes the data, which also hints the presence of some kinds of clouds in the atmosphere of WASP-39 b. Spectral feature due to other chemical species are also shown in the plot. ~ Tonmoy Deka. #JWST #Exoplanet #Atmosphere #Astronomy #Chemistry
