Wednesday will bring an unusual concentration of celestial events: a total solar eclipse, the peak of the Perseid meteor shower and a six-planet parade — while NASA […]
A Sunspot Cluster On-Par With the One That Triggered the Carrington Event Has Appeared on the Sun
The largest complex of sunspots recorded in over a decade has recently rotated into view from the far side of the Sun, and is currently in a position that could expose Earth to a major solar event, if the cluster were to generate one. While it is unlikely to produce a solar storm of comparable […]
A Third Interstellar Object Spotted Passing Through Earth’s Solar System
Astronomers have spotted a third interstellar object passing through our solar system, the fast-moving 3I/ATLAS, the third interstellar visitor caught passing us by since ʻOumuamua was first spotted in 2017. 3I/ATLAS was first spotted on July 1, 2025, by the Asteroid Terrestrial-impact Last Alert System (ATLAS) survey telescope located in Río Hurtado, Chile, when it was still four-and-a-half […]
Defying Expectations, Solar Activity Returns to a 23-Year High
Defying expectations, solar activity is back in a big way, with the number of sunspots counted on the Sun’s surface last month reaching levels not seen in nearly 23 years, more than twice the number predicted by previous forecasts. This newfound activity signals not only that the Sun is well within this cycle’s solar max, […]
