What NASA discovered on the largest worlds in the asteroid belt
When NASA’s Dawn spacecraft finally reached the giant asteroids Vesta and Ceres, scientists expected simple rocky worlds. Instead, the mission revealed mysterious bright spots, signs of icy eruptions, and strange geological features that challenged earlier theories about the asteroid belt. One world even showed evidence of cryovolcanoes erupting salty water into space. The discoveries suggest these bodies may be far more complex than the small remnants scientists once believed.

Delays with SpaceX’s Starship risk NASA moon landing timeline
SpaceX’s Starship has accumulated at least two years of development delays since NASA picked the rocket as an astronaut moon lander in 2021, and is expected to require more time to clear remaining hurdles before landing on the moon, NASA’s inspector general said Tuesday as the agency studies plans to speed up the program.NASA has been working with an array of companies, most prominently Elon Musk’s SpaceX and Jeff Bezos’ Blue Origin, in its...
Scientists have no idea if most of America’s bugs are dying out
Study finds 88% of North American insects haven’t been assessed for extinction risk In A Nutshell The conservation status of 88.5% of North American insect and arachnid species is entirely unknown, leaving most with no path to legal protection. Of the insects and arachnids confirmed as at-risk, 94.7% are protected by no federal or state law, compared to 27.7% of at-risk bird species that receive federal protection. Conservation protections favor...

Up to 1 foot of tephra buries parts of Hawaii Volcanoes National Park after Kilauea eruption
KÄ«lauea's March 10 eruption sent inches to nearly 1 foot of tephra raining down on parts of Hawaii Volcanoes National Park, burying overlooks, roads and grassy areas under volcanic rock, ash and glass. The eruption began Tuesday morning and lasted nine hours. Lava fountains soared as high as 1,300 feet, producing widespread tephra fall across the summit, onto Highway 11 and into nearby communities. Episode 43 lava fountains, plume and tephra...
Study: North Sea asteroid triggered a 330-ft tsunami near Hull
A massive asteroid slammed into the southern North Sea between 43 and 46 million years ago, producing a 330-foot tsunami that would have surged toward ancient coastlines near what is now Hull, England. The collision left behind the Silverpit Crater, a 20-km-diameter multi-ringed structure buried beneath the seabed, and its true origin has been the […]
Watch what happens when a penny is dropped from a skyscraper
For years, people have warned that a penny dropped from a skyscraper could kill someone below. To find out if the famous story is true, researchers recreated the scenario by dropping pennies from above and measuring the impact. The results reveal how air resistance limits the speed of small objects, even after long falls. The surprising experiment shows why the skyscraper penny myth doesn’t behave the way many people expect.
Why scientists want to chase a mysterious object already billions of kilometers away
In 2017, astronomers spotted something unprecedented: a mysterious object from outside our solar system racing past the Sun. Known as ‘Oumuamua, it behaved in ways scientists still struggle to explain, including a strange burst of acceleration that didn’t match normal comets or asteroids. Now researchers are proposing a bold mission to chase the object deep into interstellar space, even though it’s already more than 6 billion kilometers away. The question is whether we can reach it before its secrets vanish forever.
The truth behind SpaceX’s exploding rockets
SpaceX has transformed the space industry, but its rockets have also developed a reputation for dramatic test failures and mid-flight explosions. The company argues these setbacks are part of an aggressive engineering philosophy that treats failure as a crucial step toward rapid innovation. Critics, however, worry that the pace of development may come with real technical, environmental, and safety risks. As SpaceX becomes the dominant force in modern spaceflight, the stakes behind every rocket launch are higher than ever.

Scientists may have found a completely new mineral hidden on Mars
Scientists studying sulfate-rich terrains on Mars believe they may have identified a previously unknown mineral hidden in layered deposits near the planet’s vast canyon system. By combining spacecraft observations with laboratory experiments, researchers traced unusual spectral signals to a rare iron sulfate compound. Sulfate minerals are common on...
Earth's days are getting longer at unprecedented rate not seen in 3.6 million years – here's why
Earth's spin is slowing down and our days are getting ever-so-slightly longer. While the planet's rotation often speeds up and slows down over time, new research suggests the current increase in day length is unprecedented in at least 3.6 million years of history. In theory, it takes 24 hours for Earth to complete one rotation. In reality, a day ca...
Elon Musk revealed a plan to reach other stars – and it starts with Mars
Elon Musk believes humanity’s future lies far beyond Earth — and even beyond Mars. SpaceX is already building the massive Starship rocket designed to transport hundreds of tons across the solar system. But the long-term vision goes further: nuclear-powered starships, antimatter engines, and even theoretical warp drives that could one day reach other star systems. The first step is colonizing Mars and building a thriving space economy. From there, the journey to the stars may begin.
A single experiment ended 2,000 years of scientific belief
Science prides itself on self-correction — but history shows it has taken some spectacular wrong turns. For over two millennia, spontaneous generation was accepted as fact, claiming life could emerge from rotting meat or mud. Physicists defended invisible substances like phlogiston and luminiferous ether, while astronomers convinced themselves Mars was covered in artificial canals. These weren’t fringe ideas — they were mainstream science, until better experiments shattered them.

Chinese physicists create elusive 'hexagonal diamond' that's harder than natural diamond
Researchers made small, pure samples of the elusive mineral lonsdaleite – also known as hexagonal diamond — and tested its material properties to show it's harder than diamond.
A mystery rocket crashed into the moon - and no one claimed it
In March 2022, a mysterious rocket booster that had been drifting through space for years finally crashed into the surface of the Moon, creating an unusual double crater that puzzled scientists. Astronomers traced the object’s path and concluded it was likely connected to an earlier Chinese lunar mission, although the origin sparked debate. The incident highlighted a growing problem in space: untracked debris and weak international regulations governing activity beyond Earth. As more nations and private companies launch spacecraft, experts warn that space could become increasingly crowded and potentially dangerous.
Giant 'space laser' found shining towards Earth from 8,000,000,000 light-years away
The powerful emission, known as a gigamaser, was discovered using the MeerKAT radio telescope in South Africa.
