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.
We will never, ever tell you to stare at the sun. Fortunately, we have a far better way for you to get a glimpse of the upcoming ring-of-fire solar eclipse.
NASA’s Solar Dynamics Observatory just released a stunning video showing a pair of magnetic fields as they duel for supremacy on the surface of the sun.
Sometimes there are just no words. Sometimes there is just a tree and a setting Sun and a sky that turns from a bright yellow to a deep orange. The Film Artist made this video, Be Sunset Tree, and it’s just majestic. How the Sun crosses the tree, how the tree seemingly cradles the light, and how the sky looks like it’s on fire.
