A bright meteor flew through the skies over northern Utah on Saturday morning, later raining down meteorites over the Great Salt Lake. Residents of the Salt Lake City area were startled by loud booms at 8:30 a.m. MDT on Saturday, Aug. 13, 2022. Eyewitnesses saw a fireball in the sky, 16 times brighter than the full Moon.

Credits: NOAA Approximately 22,000 miles out in space, NOAA’s Geostationary Lightning Mappers (GLM) onboard the Geostationary Operational Environmental Satellites (GOES) 17 and 18 detected the meteor, which was first seen 50 miles over West Valley City. However, it is difficult to pinpoint its exact trajectory. “Daytime fireballs are very tough to analyze,” said Bill Cook...

On June 10, people in parts of the northern hemisphere will have the chance to witness a solar eclipse.Watch the full visualization of the eclipse.The June 10 eclipse is an annular solar eclipse, meaning that the Sun will never be completely covered by the Moon. The Moon’s orbit around the Earth is not a perfect circle, so throughout each month, the Moon’s distance from Earth varies. During an annular eclipse, the Moon is far enough away from Earth that the Moon appears smaller than the Sun in the sky. Since the Moon does not block the entire view of the Sun, it will look like a dark disk on top of a larger, bright disk. This creates what looks like a ring of fire around the Moon.People in the narrow path of annularity — which, for this eclipse, cuts through Canada, Greenland, and northern...

Updated 8:25 p.m. Eastern with post-launch statement. TOKYO — Firefly Aerospace placed eight cubesats into orbit on a mission funded by NASA on the first flight of the company’s Alpha rocket since an upper stage malfunction more than half a year ago. The Alpha rocket lifted off from a foggy Vandenberg Space Force Base in California at 12:04 a.m. Eastern July 4. A launch attempt July 2 was scrubbed after a ground equipment issue halted the countdown just before ignition of the rocket’s first stage engines. The rocket started deploying its payload of eight cubesats about 35 minutes after the upper stage shut down, a process expected to last about 11 minutes according to a timeline provided by Firefly. The orbit was a low Earth orbit, but Firefly did not disclose the sp...

They say a picture is worth a thousand words, but no images have left a greater impact on our understanding of the universe quite like the Hubble Space Telescope’s deep fields. Like time machines, these iconic images transport humanity billions of light-years back in time, offering a glimpse into the early universe and insight into galaxy evolution!You’ve probably seen these images before, but what exactly do we see within them? Deep field images are basically core samples of our universe. By peering into a small portion of the night sky, we embark on a journey through space and time as thousands of galaxies appear before our very eyes.So, how can a telescope the size of a school bus orbiting 340 miles above Earth uncover these mind-boggling galactic masterpieces? We’re here to break it do...
