The gigantic galaxies we see in the Universe today, including our own Milky Way galaxy, started out far smaller.
A few years ago, astronomers uncovered one of the Milky Way's greatest secrets: an enormous, wave-shaped chain of gaseous clouds in our sun's backyard, giving birth to clusters of stars along the spiral arm of the our galaxy.
Hundreds of novel ingredients never encountered by human physiology are now found in nearly 60 percent of the average adult's diet and nearly 70 percent of children's diets.
A potentially game-changing and largely unexplored energy jackpot lies beneath the ocean floor. Unique conditions under the sea bed promise cheaper and more accessible geothermal power.
The icy dwarf planets Eris and Makemake have surfaces bearing methane ice of unknown origin. The two planets may have warm oceans.
New measurements by NASA’s New Horizons spacecraft show higher than model-predicted levels of interstellar dust as the spacecraft approaches the putative outer edge of the Kuiper Belt.
The quasar – named J0529-4351 – is both the most luminous object known to date and the fastest-growing black hole currently known.
Less than a year after its opening, the Facility for Rare Isotope Beams produced five never-before-seen isotopes for observation, a success that researchers say highlights the discovery potential of the facility.
Does life appear independently on different planets in the galaxy? Or does it spread from world to world? Or does it do both? New research shows how life could spread via a basic, simple pathway: cosmic dust.
Spanish Researchers have captured the world's first high-resolution images of the earliest moments of microtubule formation inside human cells.
Older adults are twice as likely to develop dementia if they’ve been infected with the herpes simplex virus, a new 15-year study concludes.
A new study weighed a range of threats and variables in an effort to map out where the rainforest is most vulnerable.
Millions of years ago, vertebrates were infected by a virus, which played an important role in the evolution of human beings and the development of brains and human bodies.
A satellite that measures methane leaks from oil and gas companies is set to start circulating the Earth 15 times a day next month.
For a quiet, dusty lump of a planet we see today, Mars has had a surprisingly violent history, one that could reveal some clues about Earth.
