The Milky Way isn't like other barred spiral galaxies. Instead of a nice, tidy flat disc, it has a kink in its spine, a twist in its swagger. As we have long known, and two separate studies recently confirmed, the Milky Way is seriously warped around the edges, a strange idiosyncrasy that's been puzzling astronomers for years.
Milky Way is warped; it may be the legacy of an ongoing galactic collision
Researchers have discovered a huge snowman-shaped star with an atmospheric composition never seen before.
Huge ‘space snowman’ is two merging stars
Scientists have found evidence that Earth was covered by a global ocean that turned the planet into a “water world” more than three billion years ago.
Earth may have been a 'water world' three billion years ago: Scientists
Antidepressants like Prozac and stimulants like methamphetamine may well be responsible for creating one of the most potent toxins found in tap water.
Prozac, methamphetamine likely responsible for toxins in tap water
Artificial intelligence (AI) has the potential to improve efficiencies and precision in sleep medicine, resulting in more patient-centered care and better outcomes, according to a new position statement from the American Academy of Sleep Medicine (AASM).
AI could enhance diagnosis and treatment of sleep disorders
Drivers hoping their new plug-in hybrid car will help cut down their carbon footprint may have an unlikely enemy: Cold weather.
Hybrid carmakers accused of 'con' over zero-emissions claims
A new discovery could be a clue for us to see if life could emerge elsewhere in the solar system. Using a new analysis technique, scientists think they have found an extraterrestrial protein, tucked inside a meteorite that fell to Earth 30 years ago.
Scientists claim to have found first known extraterrestrial protein in meteorite
If humanity fails to find a way through this train wreck of a climate crisis, we might want a form of record-keeping that doesn't decay after a generation or two. You know, just to let future intelligences know we had some redeeming qualities.
Tiny microbe may be perfect time capsule for messaging future civilizations
In the coming decades, new rovers will roam the sands of Mars. An orbiter will sample the seas of Jupiter's moon Europa. A drone will grace the skies of Saturn's moon Titan. Mission planners dream of equipping these mechanical scouts with instruments capable of scouring the unknown environments for signs of life, but the technology required to do so is deceptively complex.
How NASA is using synthetic DNA in its search for alien life
Turbulence is everywhere – it rattles our planes and makes tiny whirlpools in our bathtubs – but it is one of the least understood phenomena in classical physics.
