NASA Update News: NASA Science Chief Announces His Retirement; Leaves A Legacy Of Success John Grunsfeld, head of NASA’s Earth and Space science activities, former astronaut and chief scientists will retire on April 30. He has been in the service for four decades and would leave a remarkable legacy in the history of science and exploration. Space reports that Grunsfeld led the NASA’s Science Mission Directorate since 2012. He managed over 100 missions. These include the New Horizon’s…

Describe the development of single dish radio telescopes and advantages of radio interferometers. Discuss major discoveries that were possible after detection of radio waves from space and how they changed our understanding of Universe. Astronomy is all about increasing our understandings about our Universe through observing objects like stars, galaxies and other bodies which exist outside Earth’s atmosphere. Astronomers make observations of these celestial phenomena by collecting…

women. These women have been cheated and lied about. But why? People have not been very nice to women through science, in fact you could even say that they were being very sexist. Take for example Jocelyn Bell Burnell, she discovered those little pulsars from the stars in the universe that went supernova. This took her dedication, and most likely countless hours of lost sleep. But then she passed away just after she had about wrapped up her research. When it came time to give her recognition…

It is important to acknowledge that without the critical state, interesting phenomena cannot occur. The non-critical state is at equilibrium, where Gibb’s free energy is equal to zero, and there are no avalanches. Therefore, the critical state is not at equilibrium, this is only an illusion society sees as a result of the nature of self-organized critical systems. During the intermittent periods between avalanches, society cannot detect any changes, so it is assumed that nothing is happening,…

For 13 years, the scientists of LIGO—the most ambitious, and expensive, project in the history of the National Science Foundation—had been waiting. LIGO, the Laser Interferometer Gravitational-Wave Observatory, has been twenty-five years and more than half a billion dollars in the making. It involves 900 scientists and engineers, including many whose entire careers have been spent designing, building, and preparing to analyze data streaming in to LIGO. Their goal: To confirm, once and for all,…

Culture and strategy are two most critical buildings blocks for an organisation. It is like an engine and piston which has to run together for a smooth functioning. There have been cases where the entire organisation was saved from bankruptcy as they had a very strong culture and at the same time, organisations were not able to transform to the new technology and environment due to a very resilient culture (Examples to follow). Hence, in our understanding, strategy needs to be implemented…

• 24 Youth participated in two new STEM 4-H Clubs—Plane Janes 4-H Coding Club and the SPIN Pulsar Club. The extension agent was able to acquire $3,450 to support STEM programming in Kanawha County including the establishment of a new Computer Coding Club and a countywide STEM Maker Day Event. Additional funding ($73,000) from the Greater Kanawha…

An exoplanet is described as a planet that orbits a star outside our solar system. The majority of the exoplanets scientists have discovered were found in the past two decades, mainly with the Kepler space telescope. These planets are all different in orbit, size, and type. Some are smaller than Jupiter, or even larger than Jupiter, but essentially all of the exoplanets that we know of a larger than the Earth. Scientists have even found planets that orbit two stars, as opposed to the normal one.…

Time is a concept that for a long time was thought to be untouchable. This was until black holes were discovered. These collections of matter hold the seemingly supernatural effect to alter time as we know it. A black hole is a star that has collapsed and become so dense that it creates a gravitational field strong enough that nothing, not even light, can escape. When a star dies it leaves behind a very dense remnant core. If the core’s mass is more than three times the mass of the sun, the…
