The sun has a big year in 2024, starting with a total solar eclipse across the US. NASA's Parker Solar Probe will fly closer to the sun than any spacecraft ever, almost landing on it. One of the main events this year will be a historically cool total solar eclipse crossing the US in April. AdvertisementIn a total solar eclipse, the moon passes in front of the sun as seen from Earth, darkening the sky. For example, NASA is launching three rockets during the April total solar eclipse, loaded with instruments to study how the sudden darkness changes our upper atmosphere.

ESA & NASA/Solar Orbiter/EUI team/Handout via REUTERS File Photo Acquire Licensing RightsBENGALURU, Sept 2 (Reuters) - Following quickly on the success of India's moon landing, the country's space agency launched a rocket on Saturday to study the sun in its first solar mission. The rocket left a trail of smoke and fire as scientists clapped, a live broadcast on the Indian Space Research Organisation's (ISRO) website showed. While Russia had a more powerful rocket, India's Chandrayaan-3 out-endured the Luna-25 to execute a textbook landing. Prime Minister Modi is pushing for India's space missions to play a larger role on a world stage dominated by the United States and China. Satellites in low earth orbit are the main focus of global private players, which makes the Aditya-L1 mission a very important project," he said.

The Chandrayaan-3 spacecraft landed on the lunar surface near the moon's south pole on Wednesday. The historic occasion marked the country as a global space power and only the fourth nation to achieve a lunar landing. Chandrayaan-3 has already returned several images and rolled out its Pragyan rover on the lunar surface. Meanwhile, Russia’s Luna 25 lander crashed into the moon, causing experts to question the country’s future lunar ambitions.

REUTERS/Amit Dave Acquire Licensing RightsBENGALURU, Aug 25 (Reuters) - On the heels of the success of the Chandrayaan-3 moon landing, India's space agency has set a date for its next mission - this time to study the sun. It aims to study solar winds, which can cause disturbance on earth and are commonly seen as "auroras". In 2019, the government sanctioned the equivalent of about $46 million for the Aditya-L1 mission. The Indian space agency has earned a reputation for world-beating cost competitiveness in space engineering that executives and planners expect will boost its now-privatised space industry. The Chandrayaan-3 mission, which landed a spacecraft on the lunar south pole, had a budget of about $75 million.

☆ Solar Orbiter observes jets of material escaping the sun

CNN —The Solar Orbiter mission has discovered jets of material rapidly releasing from the sun’s outer atmosphere. An artist's concept shows the Solar Orbiter spacecraft circling the sun. The advanced instruments aboard Solar Orbiter, as well as NASA’s Parker Solar Probe, are helping to unlock the biggest mysteries that remain about the sun. The sun’s magnetic field is so massive that it stretches beyond Pluto, providing a pathway for solar wind to travel directly across the solar system. Solar Orbiter works in tandem with Parker Solar Probe, which is orbiting the sun on a seven-year mission after launching in August 2018.

The sun as seen by the Solar Orbiter spacecraft in extreme ultraviolet light in this mosaic of 25 individual images taken on March 7, 2023, by the high resolution telescope of the Extreme Ultraviolet Imager (EUI) instrument. New observations by the Solar Orbiter spacecraft may provide an answer. "Unlike the wind on Earth that circulates the globe, solar wind is ejected outward into interplanetary space," Chitta said. "Earth and the other planets in the solar system whiz through the solar wind as they orbit around the sun. "This finding is important as it sheds more light on the physical mechanism of the solar wind generation," said solar physicist and study co-author Andrei Zhukov of the Royal Observatory of Belgium.

☆ The sun’s activity is peaking sooner than expected
▼ + stars: | 2023-07-14 | by ( Ashley Strickland | ) edition.cnn.com time to read: +11 min

Every 11 years or so, the sun experiences periods of low and high solar activity, which is associated with the amount of sunspots on its surface. Over the course of a solar cycle, the sun will transition from a calm to an intense and active period. During the peak of activity, called solar maximum, the sun’s magnetic poles flip. A solar activity spikeThe current solar cycle, known as Solar Cycle 25, has been full of activity, more so than expected. The solar storms generated by the sun can affect electric power grids, GPS and aviation, and satellites in low-Earth orbit.

☆ First mission to ‘touch’ the sun catches the solar wind

The slower solar wind, located in the same plane of the solar system as Earth, flows at a calmer 249 miles per second (400 kilometers per second). This flip causes the coronal holes to appear across the sun’s surface and release bursts of solar wind directly toward Earth. JHU Applied Physics Laboratory/NASA's Goddard Space Flight CenterUnderstanding the source of the solar wind can help scientists better predict space weather and solar storms that can affect Earth. Fortunately, Parker Solar Probe and a separate mission, Solar Orbiter, are perfectly poised to observe the sun’s powerful, dynamic forces at play. “There was some consternation at the beginning of the solar probe mission that we’re going to launch this thing right into the quietest, most dull part of the solar cycle,” Bale said.

☆ Solar telescope’s images reveal the sun’s surface like never before
▼ + stars: | 2023-05-25 | by ( Ashley Strickland | ) edition.cnn.com time to read: +4 min

CNN —New images of the sun’s surface captured by a powerful ground-based solar telescope have revealed sunspots and other features in unprecedented detail. The eight images, released on May 19, were taken using the National Science Foundation’s Daniel K. Inouye Solar Telescope, a 4-meter (13.1-foot) telescope located on the island of Maui in Hawaii. Although the sun is becoming increasingly active as the July 2025 solar maximum — the peak of the sun’s 11-year cycle — draws closer, the photos showcase the quieter aspects of the solar surface. Bright hot plasma flows upward on the sun’s surface, while darker, cooler plasma flows down. NSF/AURA/NSOThe Inouye Solar Telescope also glimpsed “light bridges,” bright solar features that span the darkest region of a sunspot.

NASA’s Solar Dynamics Observatory captured this image of a solar flare – as seen in the bright flash on the upper right – on March 3, 2023. CMEs are common culprits of solar storms on Earth, since they can send a powerful flood of solar particles washing over the planet.

These 'holes' can send 1.8 million mph solar winds towards Earth. As this first 'hole' begins rotating away from us, a new giant coronal hole — about 18 to 20 Earths' across — has come into view. Coronal holes release solar winds into space which can damage satellites and reveal stunning auroras if they reach the Earth. The 'hole' is positioned close to the sun's equatorThe coronal hole came into view as the sun rotated. The solar winds can blast very fast solar winds, with speeds of more than 800 kilometers per second, Verscharen said.
