13 Things You Didn't Know About Space Travel

Space causes vision problems Enrique Ramos/Shutterstock Another physical challenge: More than half of American astronauts suffered from vision problems, especially after long-duration space station flights. Researchers say the issues could be related to fluid shifts in the body that put pressure on the eye nerves. The pressure can also permanently flatten the shape of the […]

California's massive wildfires are pushing carbon monoxide across the country

It was just a few days ago that the National Weather Service provided some stunning glimpses at the effect the California wildfires are having on weather patterns in the United States, and now NASA is chiming in with its own discoveries. The NWS revealed that massive smoke clouds pushed aloft by the fires were gradually […]

This teeny, tiny galaxy is hiding a supermassive black hole

This teeny, tiny galaxy is hiding a supermassive black hole

A small galaxy some 70 million light-years from Earth has been hiding a big secret. This week, astronomers announced they’d found a supermassive black hole (SMBH) lurking at the center of a galaxy called Fornax UCD3. It’s an odd place for such a giant black hole to survive. Supermassive black holes commonly thrive at the […]

Cracking Open The Hearts of Dead Suns

Neutron stars are extreme objects composed of 95 percent neutrons and five percent protons.(Credit: NASA’s Goddard Space Flight Center) Neutron stars are the remnants of violent supernovas, all that’s left behind when a star tens of times the mass of our sun ends its nuclear fuel-burning life. These extreme objects pack more mass than our […]

MIT scientists crack the case of breaking spaghetti in two

The trick to breaking spaghetti in half is to bend and twist, new MIT study says. Pasta purists insist on plonking dry spaghetti into the boiling pot whole, but should you rebel against convention and try to break the strands in half, you’ll probably end up with a mess of scattered pieces. Now, two MIT […]

The exoplanet, named KELT-9b, is the hottest alien world ever discovered. The planet is so scorching, it’s […]

Earth Has 'Minimoons,' and They May Solve Asteroid Mysteries

Earth Has 'Minimoons,' and They May Solve Asteroid Mysteries

Earth is surrounded by a host of asteroids, some of which may temporarily become “minimoons.” Credit: P. Carril/NASA Earth has a habit of picking up, and later discarding, small companions called “minimoons,” and these tiny objects could help scientists solve the mysteries of asteroids. That’s the conclusion of a recent paper, which looked […]

Russian cosmonauts prep for spacewalk

Clad in pressurized spacesuits, Russian cosmonauts plan to head outside the International Space Station on Wednesday to hand-release four tiny CubeSats and install hardware for a German experiment to track animal migration. Russian flight engineers Oleg Artemyev and Sergey Prokopyev are set to head out of the station’s Pirs airlock at 1558 GMT (11:58 a.m. EDT) […]
