Variations in the brightness of a neutron star—magnetar—during its most violent periods have been recorded for the first time.

February 2, 2021 at 6:30 am Scientists have finally gotten a clear view of the spark that sets off a weird type of lightning called a blue jet. Lightning bolts usually are seen zipping from thunderclouds down toward the ground. But blue jets shoot up from clouds. They ascend high into a layer of the atmosphere called the stratosphere. In less than a second, a blue jet can reach about 50 kilometers (31 miles) above the ground. In the stratosphere, this electricity excites mostly nitrogen gas. That nitrogen glows blue, giving these jets their signature color. Blue jets have been seen from the g...

Scientists have gotten a look at what it is that causes a strange electrical phenomenon called blue jet lightning. Instruments on the International Space Station did what had been impossible for scientists on land. Per Science News's breakdown, blue jets -- which fire upward from lightning clouds [...]

Rare and exotic upside-down lightning might be quite mundane after all In the time it has taken me to write this, lightning has struck the earth over 500 times. It is one of the most spectacular, mesmerizing, and awe-inspiring natural phenomena. For all of its beauty and power, it still holds many mysteries. As recently as the 1990s, we had only anecdotal evidence of the majority of lightning’s many incarnations. At that time, thanks to videotape evidence from NASA’s Space Shuttle missions, actual observations of sprites, jets, and later ELVES (Emissions of Light and Very Low-Frequency Pe...

21 JANUARY 2021 Of all the weather phenomena our magnificent planet throws at us, lightning is one of the most spectacular - and the most mysterious. Even though storms are a regular occurrence, we're still at pains to understand and describe their crackling electrical discharges generated in the sky.   One kind of lightning is so strange and rare, in fact, that we didn't even have concrete evidence it existed until 1990, when researchers identified its signature 'rocket-like' motion in video shot from NASA's Space Shuttle the previous year. Later dubbed 'blue jets', the streaks are now r...
