Carl Sagan (1934-1996, American) could be called the astronomer o.docxannandleola
Carl Sagan (1934-1996, American) could be called 'the astronomer of the people'. He popularized the science of astronomy with the general public, and revolutionized science fiction by believing that we are not alone in the universe. He championed the search for extraterrestrial intelligence, which continues today with a number of missions to Mars to search for signs of life on that planet.
Subramanyan Chandrasekhar (1910-1995, Indian-born American) made important contributions to the theory of stellar evolution. He found that the limit, now called the Chandrasekhar limit, to the stability of white dwarf stars is 1.4 solar masses: any star larger than this cannot be stable as a white dwarf.
Karl Jansky (1905-1950, American) discovered that radio waves are emanating from space, which led to the science of radio astronomy.
Jan Oort (1900-1992, Dutch) first measured the distance between our solar system and the center of the Milky Way Galaxy and calculated the mass of the Milky Way. An enormous contribution of his was the proposal of a large number of icy comets left over from the formation of the solar system, now known as the Oort Cloud.
Edwin Hubble (1889-1953, American) made an incredible contribution to astronomy and cosmology when he discovered that faraway galaxies are moving away from us. Known as Hubble's Law, the theory states that galaxies recede from each other at a rate proportional to their distance from each other. This concept is a cornerstone of the Big Bang model of the universe.
Albert Einstein (1879-1955, German) was probably the greatest mind of the twentieth century. His Special Theory of Relativity, proposed in 1905, extended Newtonian Mechanics to very large speeds close to the speed of light. It describes the changes in measurements of physical phenomena when viewed by observers who are in motion relative to the phenomena. In 1915, Einstein extended this further in the General Theory of Relativity, which includes the effects of gravitation. According to this theory, mass and energy determine the geometry of spacetime, and curvatures of spacetime manifest themselves in gravitational forces.
Annie Jump Cannon (1863-1941, American) was a member of the famous group of Harvard astronomers called 'Pickering's Women'. The director of the Harvard College Observatory, Edward Pickering, hired a number of women to sort through and organize mounds of data on the stellar classification of stars. The stars were classified by their spectra, and Annie Cannon was the most prolific and careful of the workers. She single-handedly classified 400,000 stars into the scheme we use today (O B A F G K M), and discovered 300 variable stars. She paved the way for women entering the astronomical field.
Joseph von Fraunhofer (1787-1826, German) discovered dark lines in the spectrum coming from the Sun. He carefully measured the positions of over 300 of these lines, creating a wavelength standard that is still in use today.
Isaac Newton (1643-1727,.
Nobel Prize in Astronomy? Nonsense, you will say, there is no such thing! And you will be right! Today I would like to talk about the Nobel Prizes in Physics awarded for the discoveries directly related to Astronomy. Of course, many scientific advances contributed to the modern understanding of Space. But let’s look at those few that achieved the highest scientific recognition.
Submanyan Chandrasekhar received the Prize for his research “on the structure and evolution of stars”. His work helped us understand how stars age and die. Chandrasekhar calculated what we now call Chandrasekhar limit, which is equal to 1.4 Solar mass. Chandrasekhar showed that if the dying star has a mass of 1.4 Solar mass or less when it reaches the white dwarf stage, it stays a white dwarf forever. A heavier star will continue collapsing and eventually turn into a neutron star or a black hole. You can find more information about Chandrasekhar and his research in our post.
Potential Habitable Exoplanets: Interstellar Space Travel As Mankind's SalvationAhmad Afandi Nor Azmi
Humans are natural born explorers, we charge into unchartered territory to seek out the unknown, we have mapped nearly every inch of Mother Earth and left tracks on the moon. But to set foot on another planet, to travel beyond our solar system, that’s the dream of the future.
This presentation deals with quest of new worlds and the fate of humanity. Sounds like a job for explorers of tomorrow, but the search of another earth is happening right now. Although this sounds like a realm of science fiction, the aspects covered are rooted in real science.
I can identify key technological advancements that helped in making our knowledge of space expand. My research will show the past, but I will also predict what future advancements may stretch our limits even more.
Earth-Like Planet with Intelligent Life? Why 400 Years?Paul H. Carr
Earth-Like Planet with Intelligent Life? Why 400 Years?
Paul H. Carr, Ph. D.
In 1584, Dominican monk Giordano Bruno envisioned the stars as "countless suns with countless earths, all rotating around their suns.” Searching for intellectual freedom, he fled his native Italy to Protestant Switzerland and Germany, but in 1600 the Roman Inquisition condemned him for heresy. He was burned at the stake.
Fast-forwarding to 1995, the Swiss astronomers Michel Mayor and Didier Queloz announced the discovery of a planet orbiting a star similar to our sun (51 Pegasi). In 2010, 500 planets had been found orbiting 421 stars. On Feb 2, 2011, NASA announced that the Kepler space telescope had identified 1200 planet candidates.
It took 400 years for telescope technology to advance and for Copernicus, Galileo, Newton, Bradley, and Foucault to establish heliocentric cosmology, culminating in today’s astrophysics with digital imaging and processing. Here is your opportunity to learn about the progress we are making towards discovering an earth-like planet with the possibility of intelligent life. Contrasting with Bruno, in 2010 Dominican Francisco Ayala, who had been president of the Sigma Xi and AAAS, won the $1.6M Templeton Prize for affirming life’s spiritual dimension.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Scientific events 1945 1968
1. Discovery of the structure of DNA molecule (1953)
In 1953 british molecular biologist Francis Crick with James Watson discovered the structure of DNA molecule.
Crick and Watson showed off the first model of DNA in 1951, which was unfortunately wrong. Two years later
in 1953 they finally figured out how the structure of DNA looks and they published it in Nature on 25. 4. 1953.
The Crick’s letter to his son which explained their discovery was sold for $6,059,750 in auction at Christine’s
New York on 10. 4. 2013.
First accurate atomic clock (1955)
In 1955 Louis Essen invented the first accurate atomic clock. It was cesium standard atomic clock based on
transition of caesium-133 atom. Louis Essen built it with Jack Perry at the National Physical Laboratory in the
United Kingdom. Calibration of the caesium standard atomic clock was carried out by the use of the
astronomical time scale. The Cesium standard is being used until now, for example in GPS satellites.
2. Sputnik 1 (1957)
Sputnik 1 was the firstartificial Earth satellite.Itwas constructed by Russian rocket scientist Sergei Korolev and
launched from Baikonur Cosmodrome in former Soviet Union on 4 October 1957. Sputnik has only one
scientific device – transmitter. The average of this satellite was only 58 centimetres and the weight 84
kilogrammes. Sputnik 1 burnt up on 4 January 1958, after travelling about 70 million kilometres and spending
three months in orbit.
First flight to the space (1961)
On 12 April 1961 Russian astronautYuri Gagarin travelled as a first human to the space. He flew with the space
shift called Vostok 1. It was made for one person and the weight was five tunes. The duration of the flight
around whole Earth was one hour and 48 minutes. The flight was about 200 kilometres above the Earth. He
returned without injuries after he catapulted himself 7 kilometres above the Earth.
3. Vine–Matthews–Morley hypothesis (1963)
In 1962 Harry Hess published the sea-floor spreading hypothesis. According to him, seafloor was created at
mid-oceanic ridges by the convection of the earth's mantle and pushing the old crust away. Geophysicist
Frederick John Vine and the Canadian geologist Lawrence W. Morley independently realized that it wasn’t
alright. In 1963 Drummond Hoyle Mathews joined them and together they published their own hypothesis. It
was based on the Hess’ hypothesis with some additions about geomagnetism – it basically proved that the sea
floor spreads by measuring flips in the magnetic orientation of the sea floor samples they took.
Pulsar (1967)
Pulsar is a short name for pulsating radio star. It is highly magnetized, rotating neutron star that emits a beam
of electromagnetic radiation. The effort of radiation regularly change. It calls May effect. These pulsar stars
were explored by scientists Jocelyn Bell Burnell and Antony Hewish from Cambridge University. They said that
was the new type of a star that is shine only one year.
Jaroslav Heyrovský’s Nobel prize (1959)
Jaroslav Heyrovský was a Czech chemist and inventor. He invented polarographic method for which he was
awarded with the Nobel prize on 10. 12. 1959. Ne was nominated 18 times, 14 times in chemistry, once in
4. physics and three times in physiology or medicine. He was also awarded the State Prizeand First Grade in 1951
and in 1955 the Order of the Czechoslovak Republic. On the moon is crater named Heyrovský in his honour.
