It was larger than the Earth. It was so big you could actually see it on the Sun’s surface without magnification. It contained powerful and tangled magnetic fields as well as numerous dark sunspots. Labelled AR 3664, it developed into one of the most energetic areas seen on the Sun in recent years, unleashing a […]

Northern lights don’t usually reach this far south. Magnetic chaos in the Sun’s huge Active Region 3664, however, produced a surface explosion that sent a burst of electrons, protons, and more massive, charged nuclei into the Solar System. A few days later, that coronal mass ejection (CME) impacted the Earth and triggered auroras that are […]

Right now, one of the largest sunspot groups in recent history is crossing the Sun. Active Region 3664 is not only big — it’s violent, throwing off clouds of particles into the Solar System. Some of these CMEs are already impacting the Earth, and others might follow. At the extreme, these solar storms could cause […]

An American Flamingo takes a sip of water in the Indian River at Haulover Canal on Merritt Island on Thursday, Jan. 11, 2024. The American Flamingos are more common in Mexico and Cuba but the winds from Hurricane Idalia relocated them to Florida in September 2023. Kennedy Space Center in Florida shares a border with […]

Relax and watch two black holes merge. Inspired by the first direct detection of gravitational waves in 2015, this simulation plays in slow motion but would take about one third of a second if run in real time. Set on a cosmic stage, the black holes are posed in front of stars, gas, and dust. […]

This image of the Andromeda galaxy uses data from NASA’s retired Spitzer Space Telescope. Multiple wavelengths are shown, revealing stars (in blue and cyan), dust (red), and areas of star formation. via NASA https://ift.tt/yMH2Dmw

Bright elliptical galaxy Messier 87 (M87) is home to the supermassive black hole captured in 2017 by planet Earth’s Event Horizon Telescope in the first ever image of a black hole. Giant of the Virgo galaxy cluster about 55 million light-years away, M87 is rendered in blue hues in this infrared image from the Spitzer […]

An astronaut aboard the International Space Station took this oblique photograph of the Sulaiman Mountains in central Pakistan. The range resulted from the slow-motion collision of the Indian and Eurasian tectonic plates that began about 60 million years ago. Peaks rise to more than 3,000 meters (10,000 feet) above sea level in the northern portion […]

What would it look like to circle a black hole? If the black hole was surrounded by a swirling disk of glowing and accreting gas, then the great gravity of the black hole would deflect light emitted by the disk to make it look very unusual. The featured animated video gives a visualization. The video […]
