Astronomers set a new record by continuously observing the Sun's active region NOAA 13664 for over 90 days using two spacecraft, providing valuable insights into solar activity and improving space weather predictions.
A new study warns that a severe solar storm could trigger satellite collisions in Earth's orbit within days, especially in low Earth orbit where most satellites like SpaceX's Starlink operate, potentially leading to a cascade of debris and making space unusable. The risk is higher now than in 2018 due to increased satellite numbers, and future solar storms could cause significant disruptions if satellite operators are unprepared.
A new study warns that a solar storm could disable Earth's satellite system within three days, potentially causing a chain reaction of collisions and debris that could devastate global communications, navigation, and space exploration capabilities, especially during the current solar maximum.
A new study warns that a single solar storm could disable satellite control systems, leading to catastrophic collisions in space and potentially triggering Kessler syndrome, which could make space inaccessible for humans for decades. The increasing density of satellite mega-constellations like Starlink amplifies this risk, especially since solar storms can damage satellites' navigational systems and increase atmospheric drag, making real-time control crucial to prevent disaster.
A new study warns that the risk of catastrophic satellite collisions in Earth's orbit has increased significantly, with the 'CRASH Clock' now at just 2.8 days, indicating little time to prevent disaster from solar storms or satellite debris chain reactions, potentially leading to severe space and Earth-based consequences.
A severe geomagnetic storm caused by a coronal mass ejection from the sun is expected to increase the visibility of the northern lights as far south as Texas. Tips are provided for capturing the aurora with smartphones, emphasizing stability, long exposure, and proper settings. Viewers are encouraged to find dark, northern locations away from city lights and to use features like Night Mode and a tripod for best results.
A series of solar eruptions, including coronal mass ejections, are causing a severe geomagnetic storm that is lighting up the night skies with northern lights as far south as Florida and Georgia, with potential impacts on power and communication systems.
A powerful X1.2 solar flare from sunspot region 4274 has launched a likely Earth-directed coronal mass ejection (CME), which may arrive within 12 hours and potentially cause moderate to strong geomagnetic storms on November 12, 2025.
New simulations suggest that a Carrington-level solar superstorm could wipe out all satellites orbiting Earth, causing widespread damage and highlighting the need for better preparedness as such an event is considered inevitable, occurring roughly every 500 years.
Europe's ESA conducted its most extreme space weather simulation to test responses to a solar superstorm similar to the 1859 Carrington Event, revealing that no spacecraft would survive such an event and highlighting the need for improved monitoring and preparedness for future solar storms.
Comet Lemmon was photographed flying through vibrant auroras over Scotland on October 18, just days before its closest approach to Earth, revealing a spectacular display of colors during a surprise solar storm, as the comet approaches its perihelion on November 8.
ESA conducted a comprehensive simulation of a massive solar storm, inspired by the historic Carrington event, to test spacecraft and ground system resilience, improve preparedness, and develop better forecasting tools for space weather threats, highlighting the importance of advanced monitoring satellites like the upcoming Vigil mission.
A series of four coronal mass ejections from the sun are expected to reach Earth between October 15 and 17, potentially triggering minor geomagnetic storms and impressive northern lights displays in northern regions like Canada, northern U.S., and northern Europe, with effects possibly lasting several days.
A proposed fleet of four deep-space spacecraft, including one with a large solar sail, could improve early warning of solar tornadoes or flux ropes that threaten Earth during solar storms, potentially speeding up alerts by 40% and enhancing protection for satellites and power infrastructure.
A new NOAA satellite, SWFO-L1, is launching to replace aging space weather monitoring satellites like ACE and DSCOVR, which are beyond their operational lifespans. This satellite will provide critical real-time data on solar wind and magnetic activity from Lagrange Point 1, helping to predict and prepare for solar storms that can disrupt technology and power grids on Earth.
