Solar storms can cause power blackouts, interrupt communication, and even make satellites fall to Earth prematurely. Scientists study space weather to predict it:

What are solar storms and the solar wind? 3 astrophysicists explain how particles coming from the Sun interact with Earth
Space weather isn’t referring to rain clouds that float through the galaxy. Instead, it’s caused by massive explosions of particles that shoot out from the Sun.

My PhD student Aisling O'Hare has published her first paper studying the impact of QPPs in solar flare emission on Earth's atmosphere. The ionosphere is much more sensitive to small changes in EUV irradiance than previously believed as measured by changes in total electron content. 👏

ESA @esa.int Solar Orbiter is diving towards the Sun and should be crossing the heliospheric current sheet very soon; which is anchored by a nested active region! Later this month we will try to make observations of fast solar wind sources, with coronal hole 3 looking like a promising candidate!

NASA is facing enormous cuts, half of its science budget, under DOGE.
The impacts on the agency could be devastating, possibly including the cancellation of entire missions such as Hubble, Perseverance, and Voyager.

NASA may have to cancel major space missions due to budget cuts
Potential cuts of up to 50 per cent of NASA's science budget could mean cancelling missions including the Hubble Space Telescope and the Voyager probes
