This method opens possibilities for visualizing processes like COVID-19 vaccine entry and arterial calcification. https://lnkd.in/ghMZnF7S #astronomy #space #physics

The lab is building a powerful tool to measure the light absorption of fullerenes, complex carbon cage molecules found in space. Understanding these molecules is crucial for astrochemistry, as they are considered key players in star and planet formation. #Spectroscopy #SyntecOptics

Astronomy Picture of the Day (APOD) Simulation: Two Black Holes Merge (APOD: 2024 May 10) Simulation Credit: Simulating eXtreme Spacetimes Project https://lnkd.in/dT6iHug6 Explanation: Relax and watch two black holes merge. Inspired by the first direct detection of gravitational waves in 2015, this simulation plays in slow motion but would take about one third of a second if run in real time. Set on a cosmic stage, the black holes are posed in front of stars, gas, and dust. Their extreme gravity lenses the light from behind them into Einstein rings as they spiral closer and finally merge into one. The otherwise invisible gravitational waves generated as the massive objects rapidly coalesce cause the visible image to ripple and slosh both inside and outside the Einstein rings even after the black holes have merged. Dubbed GW150914, the gravitational waves detected by LIGO are consistent with the merger of 36 and 31 solar mass black holes at a distance of 1.3 billion light-years. The final, single black hole has 63 times the mass of the Sun, with the remaining 3 solar masses converted into energy radiated in gravitational waves. https://lnkd.in/dHESFy8t #APOD

Thinking about investing in an astronomical imaging camera? Don't just focus on CCD vs. CMOS. Consider factors like resolution, field of view, sensitivity vs. noise, autoguiding benefits, software capabilities, and more. Make sure your investment aligns with your imaging needs and goals.

📃Scientific paper: Exploring NGC 2345: A Comprehensive Study of a Young Open Cluster through Photometric and Kinematic Analysis Abstract: We conducted a photometric and kinematic analysis of the young open cluster NGC 2345 using CCD \emph\{UBV\} data from 2-m Himalayan Chandra Telescope \(HCT\), \emph\{Gaia\} Data Release 3 \(DR3\), 2MASS, and the APASS datasets. We found 1732 most probable cluster members with membership probability higher than 70$\%$. The fundamental and structural parameters of the cluster are determined based on the cluster members. The mean proper motion of the cluster is estimated to be $\mu\_\{\alpha\}cos\delta$ = $\{-1.34\}\pm0.20$ and $\mu\_\{\delta\}$= $1.35\pm 0.21$ mas $yr^\{-1\}$. Based on the radial density profile, the estimated radius is $\sim$ 12.8 arcmin \(10.37 pc\). Using color-color and color-magnitude diagrams, we estimate the reddening, age, and distance to be $0.63\pm0.04$ mag, 63 $\pm$ 8 Myr, and 2.78 $\pm$ 0.78 kpc, respectively. The mass function slope for main-sequence stars is determined as $1.2\pm 0.1$. The mass function slope in the core, halo, and overall region indicates a possible hint of mass segregation. The cluster's dynamical relaxation time is 177.6 Myr, meaning ongoing mass segregation, with complete equilibrium expected in 100-110 Myr. Apex coordinates are determined as $-40^\{\circ\}.89 \pm 0.12, -44^\{\circ\}.99 \pm 0.15$. The cluster's orbit in the Galaxy suggests early dissociation in field stars due to its close proximity to the Galactic disk. ;Comment: Accepted for publication in A&A and 21 pages, 22 Figures Continued on ES/IODE ➡️ https://etcse.fr/mDI8 ------- If you find this interesting, feel free to follow, comment and share.

Combining my astronomical imaging data with that of a plate solving application allows AstroBin to plate solve my image and overlay other information over the image. This is done by recognizing star pattens against a massive database of stars. Clicking on this link will show the annotated image of Messier 17 aka the Omega Nebula. At over 800 solar masses this nebula is one of the largest in our galaxy. Imaged using my Celestron Edge 9.25 and a Peltier cooled Hyperstar Camera https://lnkd.in/giC5G8_N

Say cheese 📸 Rubin Observatory’s LSST Camera is the largest digital camera ever built. It has a resolution of 3200 megapixels. That’s so large, it would take 400 Ultra HD TV screens to display a single Rubin image. Rubin will use the camera to scan the sky once every few nights, creating a 10-year timelapse of the southern sky. It will generate more data in its first year than in all previous astronomical surveys combined. It’s not just big science — it’s paradigm-shifting science. Once operational in 2025, Rubin will be operated by NSF NOIRLab and U.S. Department of Energy Office of Science’s SLAC National Accelerator Laboratory. 📷: J.

🚀 Exciting News from Our Research Team at ESO and IIA🚀 We are thrilled to announce the publication of our latest research in the prestigious Astronomy & Astrophysics Journal! Our paper "PDS 70 unveiled by star-hopping: Total intensity, polarimetry, and millimeter imaging modeled in concert", investigates into observations and detailed modeling of the PDS 70 system, a young star surrounded by a protoplanetary disk with emerging giant planets. The work is led by Dr. Zahed Wahhaj from ESO 🌟 Key Highlights: Utilizing advanced imaging techniques, we have successfully captured the most detailed images of the planets and the disk, revealing interactions and features previously obscured. Our findings indicate significant flaring of the disk at around 50 AU from the star, with a gap within about 50 AU where dust density is remarkably low (approx. 1% of the outer disk's density). The study also suggests a complex grain-size distribution within the disk, highlighting the sophisticated dynamics shaping the system. Notably, no new planets were detected in the system beyond a separation of 0.1'', providing crucial insights into the formation and evolution of planetary systems. This research was made possible through the collaboration of an international team of experts, and represents a significant step forward in our understanding of planet formation and disk dynamics. 🔗 Read the full paper here: https://lnkd.in/d6gZDAxE 💡 For more insights and detailed discussions, don't hesitate to contact us! #Astronomy #Astrophysics #PlanetFormation #SpaceScience #ResearchHighlight #PDS70
