New Horizons returned some amazingly detailed shots and data of Pluto over the course of its mission—but just what did it have to fly through to get there? So, so much.
Astronomers have measured and mapped a weather system on a planet outside our solar system for the first time, and I’m sad to report that interstellar camping trips maaaay not be so much fun after all. On planet HD 189733b, at least, the winds are blowing at a breathtaking 5,400 miles per hour.
The aurora borealis is one of the most stunning light shows on Earth, but normally, it’s a treat reserved for the hardy souls living at the coldest edges of the world. The last few nights, however, people across the Northern and Southern hemispheres have enjoyed dazzling, colorful skies, thanks to a geomagnetic storm…
We all know that major storms can wreak havoc, flooding cities and decimating infrastructure. But there’s an even bigger worry than wind and rain: space weather. If a massive solar storm hit us, our technology would be wiped out. The entire planet could go dark.
Curiosity, our favorite little Martian space robot that could, has a new line item to add to its resume: weather-robot.
This morning, astronomers observed an incredibly powerful x-class solar flare erupting from the sun, only to be surprised by what they saw happen just about an hour later: a second x-class flare.
A Solar Dynamics Observatory video of the recent flare is a deceptively-tranquil vision of colossal energy eruption. A massive X1.4 flare is part of the highest intensity of flares releasing huge amounts of energy, yet the filaments are weirdly soothing.
On March 29th, the sun released an X-class flare. It was caught by five high-quality solar observatories on the ground and in space, creating the most detailed observations of an intense flare in history. This beautiful, rich data will help researchers better understand what triggers flares.
The UK government has announced plans to fund a new 24/7 space-weather forecasting service. As Elizabeth Gibney of Nature News reports, the Met Office warnings will protect satellites and help prevent blackouts on Earth. At a cost of £4.6-million ($7.5-million), the service could also warn of an incoming Carrington…
With all the exciting solar activity lately, NASA’s Goddard Space Flight Center shared this helpful tutorial about the vocabulary of space weather on their Facebook page. Now you can tell your CMEs apart from your solar flares.
It's decently likely that, sometime in the future, a major solar storm will hit Earth, wreaking havoc on our infrastructure and crippling our satellites. But there's a more long-term danger: space could become too dangerously radioactive to stay there.
A brown dwarf located 47 light-years away is behaving very strangely. The would-be star's brightness is constantly changing, fluctuating by as much as 30% in just eight hours. This could be an atmospheric disturbance that dwarfs Jupiter's Great Red Spot.
How accurate do you expect your local weather report to be? Honestly, I'll believe their predictions up to 48 hours, but anything beyond that is pushing it. Now it looks like our ability to predict sunspots is now at that same level, giving us valuable warning time for people in space, and infrastructure on the ground.
This picture was taken by a NASA solar observatory yesterday, and it shows one of the biggest explosions we've ever seen on the sun. For perspective, look at the upper left corner. There's a little circle the size of Earth.
The sun blasted mass quantities of plasma into space a few days ago, and the "coronal mass ejection" is headed straight for Earth. Which means we're about to get some incredible aurora displays.
Worried about solar winds and space weather interfering with global cell phone reception, possibly plunging the world into a new Dark Ages? Apparently, so is NASA: they've designed a satellite for the sole purpose of monitoring space weather.
Fueling fears about the dimming sun, scientists are predicting that the current solar cycle is not only running a year or so late, but will also be the weakest cycle since 1928. Solar disaster!
We've long seen the results of solar flares on Earth, but haven't been able to predict when they'll strike next. New research released last week has given us a better understanding of solar weather. The massive, looping jets of superheated gas that erupt from the sun are driven by giant magnetic structures that…
