Recent research proposes a new form of dark matter that may actually be lighter in mass than other dark matter candidates.
ESA's Hera mission for planetary defence made the first use of its payload for scientific purposes beyond Earth and the Moon. Activating a trio of instruments, Hera imaged the surface of the red planet as well as the face of Deimos.
Exciting new research suggests there are four miniature planets orbiting Barnard's Star, each thought to be just 20 to 30% the mass of Earth.
At least two mass extinction events in Earth's history were likely caused by the "devastating" effects of nearby supernova explosions, a new study suggests.
Around 1,645 light-years from Earth sits a binary star system, containing a white dwarf and a red dwarf on such a close orbit that each revolution smacks their magnetic fields together, producing a burst of radio waves.
A team of astronomers from Taiwan, Canada, the United States, and France has observed 128 additional moons orbiting the gas giant Saturn, bringing its total number of confirmed moons to 274.
Millions of years ago, our Solar System traveled through a densely populated galactic region and was exposed to increased interstellar dust.
A galaxy called GLIMPSE-16403, is by no means confirmed as a Population III host. But the identification of even a candidate suggests that it's only a matter of time before we finally locate the first stars in the Universe.
To lay the foundations for a lunar navigation system, NASA's Lunar GNSS Receiver Experiment (LuGRE) has successfully received global positioning system (GPS) signals beamed from Earth's orbit.
Radio astronomers see what the naked eye can't. As we study the sky with telescopes that record radio signals rather than light, we end up seeing a lot of circles.
Life's most vital elixir may have formed within 200 million years of the Big Bang, new research suggests.
Astronauts often experience immune dysfunction, skin rashes, and other inflammatory conditions while traveling in space. These issues could be due to the excessively sterile nature of spacecraft.
Ultrahigh Energy Cosmic Rays are the highest-energy particles in the universe, whose energies are more than a million times what can be achieved by humans.
Located 2.5 million light-years away, the majestic Andromeda galaxy appears to the naked eye as a faint, spindle-shaped object roughly the angular size of the full Moon.
Speedy’ planets orbiting faster in smaller orbits around white dwarfs are warmer than expected and more likely to maintain habitable conditions than the planets around the sun-like stars.
