Coronal Mass Ejections (CMEs)
12-Jun-2023: Astronomers spot a surprising solar eruption that maintains constant temperature
Scientists tracking the continuous evolution of the energy state of the core of a solar eruption that occurred on July 20, 2017, have found it strangely maintained a constant temperature as it erupted energetic and highly magnetised plasma from the solar corona into space. The finding can improve our understanding of how such eruptions can impact communication systems on Earth.
Coronal Mass Ejections (CMEs) are large-scale eruptions of charged particles (plasma) and magnetic fields from the solar atmosphere into space. They can disrupt a range of ground- and space-based technologies and satellites on Earth. Thus, it is crucial to understand their evolution and propagation through interplanetary space. There is a wide range of plasma temperatures within CMEs, from cold chromospheric material (around 104 K) to hot plasma (around 107 K). When CMEs propagate, several processes can exchange energy (electrical, kinetic, potential, thermal, and so on.), thereby heating or cooling the plasma. To understand the underlying processes, it is important to study the evolution of thermodynamic properties (such as density, temperature, thermal pressure, etc.) of CMEs. This will help our ability to monitor space weather.

9-Jun-2023: Indian Council of Agricultural Research signs a MOU with Amazon Kisan to Empower Farmers
Indian Council of Agricultural Research (ICAR), New Delhi signed a MoU with Amazon Kisan to combine strengths and create synergy between the two organizations for guiding the farmers on scientific cultivation of different crops for optimum yield and income. ICAR will provide technological backstopping to the farmers through Amazon’s network. It will improve farmers’ livelihood and boost crop yield. This MoU in farmer’s partnership with Amazon Kisan program will help ensuring access to high quality fresh produce for consumers across India, including through Amazon Fresh.
Dr Himanshu Pathak, Secretary DARE & Director General ICAR, on this occasion, emphasized upon secondary agriculture for better remuneration for the farmers. He further highlighted the importance and role of critical inputs in agriculture and season-based crop plans. He mentioned that ICAR will collaborate with Amazon for technologies, capacity building and transfer of new knowledge.

5-Jun-2023: Out of 424 foreign satellites launched till date by India, 389 were launched in the last nine years of the government headed by PM Narendra Modi
Out of 424 foreign satellites launched till date by India, 389 were launched in the last nine years of the government headed by Prime Minister Narendra Modi. Further, out of 174 million US dollars earned, 157 million came in the last nine years and similarly out of 256 million Euros earned so far, 223 million came during the 9 years of the Modi regime.
This was stated here today by Union Minister of State (Independent Charge) Science & Technology; MoS PMO, Personnel, Public Grievances, Pensions, Atomic Energy and Space Dr. Jitendra Singh today in an exclusive interview with DD News.
