Beneath its pretty pink exterior, Messier 106 harbors a monster black hole that gobbles up matter at the galaxy’s center

Scientists have altered the criteria for the habitable zone—an area not too close or far away from a star—taking into account whether planets can host liquid water. This redefines where researchers believe life-forms could exist

Balloon-borne instruments in Antarctica often fall in the first few weeks, but the Super-TIGER balloon has been airborne for 46 days, shattering a previous record of just 42 days

Recent findings back up Einstein's thinking and cast doubt on "rolling scalar fields," an alternative theory of dark energy that suggests the accelerated expansion of the universe will change over time

The fabled spaceship could join the similarly petitioned Death Star. Artificial gravity remains a big hurdle

Host of popular BBC program The Sky at Night for 55 years, Moore inspired many but was sometimes a divisive figure as well

Government satellites may start to hitch rides with commercial spacecraft in Earth orbit

Experiments to detect dark matter, which scientists believe makes up about a quarter of the universe, are underway and may yield direct evidence within a decade

Mimas and its giant parent Saturn were captured by NASA's Cassini probe, which has been exploring the solar system for 15 years

Orion, which is designed to take humans to the moon, asteroids and Mars, could carry up to four astronauts

Researchers can now calculate and use the fireball trajectory to trace the meteorite back to its origins in the Asteroid Belt

The newest measurements, courtesy of NASA's Spitzer Space Telescope, come from infrared observations of distant variable stars

The "time tunnel into the distant past" gives us a glimpse of galaxies as they looked up to 13.2 billion years ago

Scientists have envisioned a space-time crystal with cyclical structure in time as well as space

Sunita Williams ran, biked and "swam" with California triathletes to combat the muscle degeneration that comes with weightlessness

The finding could be put to use at a new facility opening in 2020 that might create new elements—that is, nuclei with more than 118 protons—in addition to new isotopes of the known elements

The same lab that first reported the shocking results last year, which could have upended modern physics, now reports that neutrinos "respect the cosmic speed limit"

The company's Falcon 9 liftoff this morning represents the potential of a new era in U.S. spaceflight, the White House science adviser says

Science fiction writers will always, by definition, be one step ahead of engineers, and interstellar travel and time travel still elude them

It's just the second new particle to be discovered at the atom smasher where physicists also seek the elusive Higgs boson particle

The "Star Trek" actor was on hand when the shuttle Enterprise flew in atop a jumbo jet Friday and explained the show's influence on the shuttle's name

A match of silicon isotopes in terrestrial and lunar rock samples is revealing more about how both bodies really formed

Scientists hope that by plotting out the distribution of dark matter throughout space, they will come closer to understanding what it is

Phobos-Grunt appears to be stuck in Earth orbit. In two weeks, if its thrusters aren't restarted, the spacecraft will be lost completely
