Vainu Bappu: The Astronomy Pioneer Who Illuminated the UniverseIn the annals of astronomy, the name Vainu Bappu shines as brightly as the celestial objects he dedicated his life to studying. Born on August 10, 1927, in Chennai, India, Vainu Bappu became one of the most prominent and influential astronomers of the 20th century, leaving an indelible mark on the field and inspiring generations of scientists.Read full article here-https://lnkd.in/dg5jMdPv

Today marks Fall Astronomy Day, a celebration of the science of astronomy and the contributions it makes to our understanding of the universe. It's a day to appreciate the beauty and complexity of celestial bodies, and to promote public awareness and education about astronomy.And tomorrow brings us the Autumnal Equinox, happening at 2:50 a.m. EDT. This is the moment when the Sun crosses the celestial equator—an extension of Earth's equator into space. This event brings nearly equal day and night lengths, signifying the official start of autumn in the Northern Hemisphere and spring in the Southern Hemisphere. In the Northern Hemisphere, this transition leads to shorter days and earlier nightfall as the Sun rises later. This pattern persists until the winter solstice, after which days gradually lengthen again.https://lnkd.in/d-z-_Zj#scienceandenvironment#AutumnalEquinox#astronomyday

As per my MSc in Astronomy, I have been scheduled for three observation nights at the Observatorio de Sierra Nevada (OSN). You may think this is a lot of time, but it is not.There are lots of constraints: the maximum airmass allowed by the telescope, the altitude of a target over the horizon, the Moon phase, the clouds...I wanted to study various comets and try to visualize some of the previous constraints. Here is the final picture. The bigger the marker, the lower the magnitude (more brilliant) the target is. As you can see, I have around 05:00 hours of dark sky without the Moon. Not all comets are visible. Note that this graph does not consider weather conditions!

For the month of March, the IAU Office of Astronomy for Education proposes to bring the SKAO telescopes into your classroom! “SKAO and the mysteries of invisible light” is a collection of activities to learn about the existence of light beyond what humans can see with their eyes and how these invisible types of light provide astronomers with a new view of the Universe.You can find this #AstroEDU activity here:https://buff.ly/48QD0tS

An international team of astronomers - including members of the NCCR PlanetS, the University of Geneva and the Université de Berne has discovered, for the second time, an Earth-sized planet around an ultra-cool red dwarf, a class of star that is very common but very difficult to detectThe SPECULOOS-3 b exoplanet is about 55 light years from Earth (which is relatively close) and is practically the same size as the blue planet.Emeline Bolmont, assistant professor in the astronomy department at the Faculty of Science | University of Geneva and director of the Life in the Universe research Center, is co-author of this study published in the journal "Nature Astronomy".#science #exoplanet #astronomy #research

"If" in the event there is a '9th planet out there' (Pluto? Anyone? Bueller?) none of our current rocket-based #propulsionsystems would ever be able to reach such a distant world or feasibly make the journey for manned #deepspace travel. The emergence of the CTPSci sciences (many are just first hearing about) brings with it the coming revelation and realization of CTP Gravitic Propulsion (https://lnkd.in/env2Rz8G) within the coming years; the 'Holy Grail' of propulsion. Future #CTPcraft (https://lnkd.in/eYycu9mT) that will utilize CTP Propulsion represents the next 'quantum leap' of human advancement and evolution #paradigm since the Wright Brothers first flight at Kitty Hawk 120 years ago. Coming advancements CTPSci sciences will offer humankind will be able to be compared much akin to 'The Expanse' (https://lnkd.in/ejmikem3) or 'Star Trek' (https://lnkd.in/eurJ2pEh) however, CTP will be 'how' such advances will occur in real life (i.e. NOT science fiction). The dawn of a new era approaches...#newbeginnings #pioneering #progress #newspaceeconomy #futurespace

🌟 Studying planets, stars, and galaxies with large reflector antennas⚡ In radio astronomy, large and highly directive microwave antennas are used to measure and study microwave radiation in the universe. 📡 As these microwave signals are weak and come from very large distances, accurate antenna design and extremely sensitive receiver systems are required. For the antenna, typically very large reflector antennas are used, such as for the Green Bank, Effelsberg, and FAST telescopes that have reflector diameters from 100 to 500 meters. 💡 In this context, TICRA’s Peter Meincke last week participated in the European School of Antennas (ESoA) on “Antennas for Radio Telescopes”, held at Stellenbosch University. Here, Peter gave a series of lectures on reflector antennas in radio astronomy, highlighting how these large and complex antennas enable radio astronomers across the globe to study planets, stars, and galaxies.
