Key numbers used Voyager 1 speed ≈ 17 km/s (typical quoted value). 1 astronomical unit (AU) = 149,597,870.7 km. 1 year ≈ 365.25 days and 1 day = 86,400 seconds. Convert Voyager speed to AU per year (digit-by-digit) Seconds per year = 86,400 × 365.25 = 31,557,600 s. Distance per year = 17 km/s × 31,557,600 s = 536,479,200 km/year. …

Fresh data from the James Webb Space Telescope (JWST) has revealed that Pluto’s weather is run by a high-altitude haze, not by its thin mix of nitrogen and methane. “This is unique in the solar system,” said Tanguy Bertrand, an astronomer at the Paris Observatory who led the analysis. His team’s Webb observations show Pluto running a climate …

As the Solar System drifts through the Milky Way, it occasionally encounters regions of space capable of reshaping Earth’s environment. Millions of years ago, one such passage may have dramatically compressed the heliosphere, allowing particles from deep space to reach our planet’s atmosphere. According to a 2024 study in Nature Astronomy, this event occurred when the Sun and planets entered …

A study analyzing data from NASA’s Parker Solar Probe has uncovered evidence of a “helicity barrier” in the Sun’s atmosphere. In 2018, NASA launched the Parker Solar Probe on a trajectory that would eventually have it dive into the Sun’s atmosphere (corona), getting seven times closer to our host star than any other spacecraft so far. In June 2025, the …

The Hubble Space Telescope has captured the best picture yet of a high-speed comet visiting our solar system from another star. NASA and the European Space Agency released the latest photos Thursday. Discovered last month by a telescope in Chile, the comet known as 3I-Atlas is only the third known interstellar object to pass our way and poses no threat …

“Then, at some point, they split apart,” says Taylor. “That can be from spinning up fast, or getting hit. That exposes ices and makes them become dark comets.” The process would also spin such objects to high speeds, which happens to be a characteristic shared by many dark comets – they spin as fast as once every six minutes, compared …

The California Supreme Court sided with environmental groups in a Thursday ruling, saying that state lawyers were wrong in their claim that the Public Utilities Commission’s decision to slash rooftop solar incentives could not be challenged. The unanimous decision sends the case brought by the three groups back to the appeals court. The groups argue the utilities commission violated state …
