Skygazers see ‘Ring of Fire’ eclipse on longest day of the year
The event also served as a dress rehearsal ahead of the total eclipse scheduled for April 2024. Both eclipses are going to be “absolutely fascinating for science,” said Madhulika Guhathakurta, heliophysics program scientist at NASA. Solar eclipses have a noticeable effect on the upper atmosphere, such as the ionosphere, which is full of charged particles…

India’s space agency aims to achieve another milestone with the launch of a probe to study the Sun on Saturday
Raychaudhuri said the mission probe will study coronal mass ejections, a periodic phenomenon in which massive discharges of plasma and magnetic energy are seen from the Sun’s atmosphere. These explosions are so powerful that they can reach Earth and potentially disrupt the operation of satellites. “Aditya will help predict the event and alert everyone so…

ISRO to launch Aditya-L1 mission to study Sun on September 2
“Physics of the solar corona and its heating mechanism. Diagnostics of coronal and coronal loop plasma: temperature, velocity and density. Evolution, dynamics and origin of CMEs”. Identify the sequence of processes occurring at several layers (chromosphere, base and extended corona) that ultimately lead to the events of the solar eruption. Magnetic field topology and magnetic…
