If alien technological civilizations exist, they almost certainly use solar energy. Along with wind, it's the cleanest, most accessible form of energy, at least here on Earth. Driven by technological advances and mass production, ...
If you have ever done any online shopping, whether it be through Amazon or another retailer, you have likely come across a review that reads something along the lines of,
Ultra-hot Jupiters (UHJs) are some of the most fascinating astronomical objects in the cosmos, classified as having orbital periods of less than approximately three days with dayside temperatures exceeding 1,930°C (3,500°F), ...
First came a rare solar eclipse, followed by the northern lights, fueled by a solar storm. The next celestial phenomenon will come next month, when skygazers can look forward to an alignment known as a "planetary parade."
Astronomers at MIT, NASA, and elsewhere have a new way to measure how fast a black hole spins, by using the wobbly aftermath from its stellar feasting.
For the first time, scientists have observed plasma waves from a solar flare focused by a coronal hole, akin to the focusing of sound waves responsible for the Rotunda effect in architecture or the focusing of light by a ...
Huge black holes are firing powerful beams of particles into space—and then changing their aim to fire at new targets. This discovery, made using NASA's Chandra X-ray Observatory and the U.S. National Science Foundation ...
The sun's surface is a brilliant display of sunspots and flares driven by the solar magnetic field, which is internally generated through a process called dynamo action. Astrophysicists have assumed that the sun's field is ...
For centuries the Makuleke community lived in the northeastern corner of South Africa, close to the modern-day border between Zimbabwe and Mozambique. But by the beginning of the 20th century, the squeeze on a disenfranchised ...
Using the Keck II telescope in Hawaii, astronomers have observed a nearby brown dwarf known as HD 33632 Ab. Results of the observational campaign, presented in a paper published May 14 on the pre-print server arXiv, provide ...
