Gazing at the night sky was once an escape from the man-made chaos on Earth. Not anymore. Nearly 70 years after Sputnik was launched, so many machines are flying through space that astronomers worry their light pollution will soon make it impossible to study other galaxies with terrestrial telescopes. There is also space debris; Nearly… Read More »
NEW YORK (AP) — Emily Hollenbeck lived with a recurring depression that she compared to a black hole; Here the gravity was so strong and his limbs were so heavy that he could hardly move. She knew the disease could kill her. Both of his mothers took their own lives. He was willing to try… Read More »
NEW YORK (AP) — Emily Hollenbeck lived with a deep, recurring depression that she compared to a black hole; Here gravity was so strong and his limbs were so heavy he could barely move.

Astronomers have discovered a hitherto unknown source of cosmic dust. Why is it important to keep track of this powder? These particles basically serve as building blocks for stars. The international team found that such dust could be created by a type of cosmic explosion that occurs when a dead white dwarf star ejects material… Read More »
A newly developed solution to the equations at its center Albert Einstein‘s most revolutionary theory suggests that hypothetical stars called “nestars” could be made from gravitational stars stacked on top of each other, or “gravastars” like Russian tea dolls, also known as matryoshka dolls. One of the most fascinating things about general relativity, Einstein’s 1915… Read More »

At the tip of the northwestern Hawaiian Islands lies Kuaihelani, also known as Midway Atoll, a small cluster of islands that are home to the world’s largest albatross colony. More than a million albatrosses return to Kuaihelani to breed each year. These seemingly pristine islands appear safe, but there’s a predator lurking among the seabirds.… Read More »
Energetic materials can come in many shapes and sizes, but they are usually in solid form and release a lot of energy through combustion or explosion, depending on their shape and the conditions they operate in. I’m a mechanical engineering professor who studies energetic materials. Making energetic materials isn’t easy, but advances in 3D printing… Read More »
Ancient cosmic light, which evenly filled the universe about 400,000 years after the Big Bang, may serve as a treasure map guiding scientists to the secrets of dark matter. The Cosmic Microwave Background (CMB) refers to the first light that circulated freely in the universe. Its journey began after space had expanded and cooled enough… Read More »
