In the hubbub after the meteorite strike, Ann Hodges became a minor celebrity. Photographs of her bruise and the damage to her home appeared in Life magazine in an article entitled, “A Big Bruiser From the Sky.”

In 1954, an Extraterrestrial Bruiser Shocked This Alabama Woman

Ann Hodges remains the only human known to have been injured by direct impact of a meteorite

Never before had scientists seen the phenomenon until they rallied colleagues around the world to view a galaxy far, far away

After two eclipse expeditions confirmed Einstein's theory of general relativity, the scientist became an international celebrity.

One Hundred Years Ago, Einstein’s Theory of General Relativity Baffled the Press and the Public

Few people claimed to fully understand it, but the esoteric theory still managed to spark the public’s imagination

Eileen Collins talked to Smithsonian about her career in the Air Force and NASA, women in aerospace and more

Illustration of a hot Jupiter planet in the Messier 67 star cluster. Hot Jupiters are so named because of their close proximity — usually just a few million miles — to their star, which drives up temperatures and can puff out the planets.

What Astronomers Can Learn From Hot Jupiters, the Scorching Giant Planets of the Galaxy

Many of the planets that are roughly the size of Jupiter orbit right next to their stars, burning at thousands of degrees

Scientists at the University of Central Florida have modeled a path toward self-sufficiency for one million settlers of Mars over the course of 100 Earth years.

The “world’s most honored woman astrophysicist” worked tirelessly for decades to measure the makeup of the sun and the stars

An artist's illustration of the planet K2-18b and another planet, K2-18c, that orbits closer to the parent star. Both planets orbit a red dwarf about 110 light-years from Earth in the constellation Leo.

The NASA rotorcraft, resembling a large quadcopter drone, will fly through the orange clouds of the ocean moon in the outer solar system

In the image captured by Cassini, the rings are illuminated both by direct sunlight and by light reflected off Saturn's cloud tops.

Saturn Could Lose Its Rings in Less Than 100 Million Years

Recent discoveries suggest that the planet’s distinctive feature may be gone in the cosmic blink of an eye

An artist's depiction of Earth during the Archean Eon, from 4 to 2.5 billion years ago, when life consisted of only single-celled microbes with no nucleus (prokaryotes). How these primitive organisms first formed from chemical reactions remains one of the greatest mysteries of science.

NASA Scientists and Astronauts Practice for Space Missions on the Seafloor

A female-led crew trained for nine days in an undersea laboratory in the Atlantic to get a sense of what it’s like to live and work in microgravity

An artist's visualization of the star S0-2 as it passes by the supermassive black hole at the galactic center. As the star gets closer to the supermassive black hole, it experiences a gravitational redshift that is predicted by Einstein's general relativity. By observing this redshift, we can test Einstein's theory of gravity.
