When you title a research paper “In Search for a Planet Better than Earth,” you’re not messing around. Earth, the only place we know for sure hosts life, sets a high bar for all other planets.
The Solar Orbiter project, a collaboration between the European Space Agency and NASA, has begun a critical new stage of the mission after the probe’s first close encounter with the Sun. Continue reading The Solar Orbiter Has Entered a Thrilling New Phase of Its Journey to the Sun
Last month, the massive, hot ball of glowing hydrogen and helium at the center of our solar system—otherwise known as our sun—released its largest solar flare since October 2017. Although it’s too early to know for certain, NASA says in a statement that this new activity might indicate that the sun is “waking up” from its cyclical slumber. Continue reading The Sun Produced Its Biggest Solar Flare Since 2017
Discovering a new star is always a delight in astronomy. So you can probably imagine the excitement over discovering a giant stream of stars winding through the Milky Way. Continue reading Astronomers found a stream of thousands of stars hiding in the Milky Way
NASA’s Parker Solar Probe just smashed the record for the fastest human-made object — but it’s just getting started on a series of feats that defy comprehension. Continue reading NASA just smashed the record for the fastest human-made object
The Sun’s impact on weather here on Earth is clear: It makes it hot or cold, it powers air currents, it causes water to evaporate making rain, et cetera. But with our increasing reliance on satellites and electronics, you can’t forget its more insidious effects—and some satellites got a taste of those yesterday.
The Earth’s atmosphere bears precious little resemblance to what it looked like at the start of the Industrial Revolution. As radio technology has advanced and spread, the signals that transmitters produce — specifically the Very Low Frequency (VLF) variety — have changed the way that the upper atmosphere and the Van Allen Radiation Belts interact, according to a study recently published in the journal Space Science Reviews. In effect, these radio waves may be enveloping the globe like an electromagnetic comforter, protecting it from satellite-frying space radiation.
