Peak tornado activity typically occurs in the region from early May to early July. It has moved an average of seven days earlier over the past six decades.
The latest science media releases highlighting exciting news and research from around the globe.
The New Horizons spacecraft – due to encounter Pluto in July 2015 – has spotted Pluto’s small, faint, outermost known moon, called Hydra.
Astronomers thought mergers formed giant elliptical galaxies. Now, for at least 24 observed galaxies, mergers have formed flattened, circular disks of dust and gas.
An international research team has developed a new system to quantify 15 years of CO2 emissions, every hour, for the entire planet, down to the city scale.
NASA scientists were in the right place at the right time this summer to capture photos of a fresh landslide, caused by an Alaska earthquake.
Astronomers spent 10 years charting stars brighter than 20th magnitude – that’s about 1 million times fainter than can be seen with the human eye.
Spinosaurus was the largest known predatory dinosaur to roam the Earth. Scientists now say that it was also the first truly semiaquatic dinosaur.
Rosetta spacecraft has been moving in tandem with its comet since August. On Monday, ESA announced the site of a November landing.
The startling results of a new survey include 17 previously unknown monuments and dozens of burial mounds surrounding Stonehenge.
The first evidence for water-ice clouds on an object beyond our solar system. It’s a brown dwarf, one of our closest neighbors, only 7 light-years away.
Reports from NOAA and elsewhere predict a chance of significant auroras, possibly observable as far south as the northern U.S. and maybe even farther south.
Fire in space doesn’t act like fire here on Earth. Untethered by gravity, flames in space curl themselves into tiny balls.
An otherworldly take take on an earthly trend, as Rosetta poses with its comet, 67P/Churyumov–Gerasimenko.
New works suggests most observed quasar phenomena depend on two things: how efficiently a central black hole is being fed and the astronomer’s viewing orientation.
European cosmologists and particle physicists come together to tweak an accepted model of how cold dark matter helps build galaxies in our universe.
The comet turns out to be a unique, multifaceted world. We now know comets can have cliffs, depressions, craters, boulders or even parallel grooves.
Tiny moons, no bigger than large mountains, may coalesce and collide with the densest part of the ring, creating luminous knots. But the moons don’t last long.
The Montreal Protocol put the brakes on ozone-depleting chemicals 30 years ago. But one compound is still abundant in Earth’s atmosphere. Where’s it coming from?
In a conservation success story, the number of California blue whales has rebounded to near historical levels after being hunted to near extinction.
Asteroid passes near Earth on September 7. At its closest (18:18 UTC / 2:18 p.m. EDT), it’s about the same distance from Earth as weather and communications satellites.
