Solar flares in May 2024 revealed Earth’s vulnerability to space weather

After losing his Pacific Palisades neighborhood in the fires that swept through Los Angeles in January, Kent Tobiska, the CEO and chief scientist at Space Environment Technologies, is reconsidering a part of his work. Specifically, he’s rethinking the danger posed by geomagnetic storms. Instead of worrying only about rare storms like the 1859 Carrington event, … Read more

Globally shark attacks are declining

Bar chart 1 1961x2048 1

International data shows 2024 was an exceptionally calm year for shark attacks on humans. The International Shark Attack File, maintained by the Florida Museum of Natural History, provides data on what are considered unprovoked bites, defined as incidents in which a person does not initiate contact with a shark. Instances in which a person intentionally … Read more

Powerful winter storm to bring heavy snow, ice, tornado risk

Winter storm warning map from the National Weather Service, February 12, 2025.

The National Weather Service said this morning: “A winter storm will continue to impact the Mid-Atlantic through tonight with areas of heavy snow, sleet and freezing rain. A winter storm will begin to impact the Central Plains Wednesday, bringing heavy snow from central Kansas through much of Lower Michigan. This system will also produce a … Read more

Gravitational waves could turn colliding neutron stars into ‘cosmic tuning forks’

The kilonova associated with GW170817 (inset) as observed by NASA's Hubble Space Telescope (visible light) and Chandra X-ray Observatory (blue) over nine days in August 2017.

Scientists have discovered a new way to probe the interiors of neutron stars by using gravitational waves to turn them into “cosmic tuning forks.” The reverberations of such ripples in spacetime could reveal the interiors of these extreme stellar remains. Born when massive stars die, neutron stars have up to two times the mass of … Read more

A Lunar Map for the Best Places to Get Samples

How can a geologic map of a lunar impact crater created billions of years ago help future human and robotic missions to the lunar surface? This is what a recent study published in The Planetary Science Journal hopes to address as an international team of researchers produced arguably the most in-depth, comprehensive, and highest resolution … Read more

NASA moves up return date for Boeing Starliner astronauts after swapping SpaceX Dragon spacecraft

NASA has decided to shuffle around some SpaceX Dragon capsules in order to launch its Crew-10 mission to the International Space Station as soon as possible. The agency is now targeting March 12 for the launch of Crew-10, which will carry three astronauts and a cosmonaut to the International Space Station (ISS). The four crewmembers … Read more

Temperamental Stars are Messing With Our Exoplanet Efforts

We have the transit method to thank for the large majority of the exoplanets we’ve discovered. When an exoplanet transits its star, the dip in starlight tells astronomers that a planet is present. Analyzing the light can tell them about the planet’s size and atmospheric properties. However, a star’s surface isn’t always uniformly heated. There … Read more

A Jumping Robot Could Leap Over Enceladus’ Geysers

Locomotion makes things move, and certain forms of locomotion make them move better than others. Those more effective types of locomotion change depending on the environment, which is even more true for space exploration. Methods that might work well on Earth or even other planets, such as helicopters, might be utterly useless on others. But, … Read more

JWST Finds the Smallest Asteroids Ever Seen in the Main Belt

This diagram shows the orbits of 2,200 potentially hazardous objects as calculated by JPL's Center for Near Earth Object Studies (CNEOS). Highlighted is the orbit of the double asteroid Didymos, the target of NASA's Double Asteroid Redirect Test (DART) mission, launched in 2021. Credit: NASA/JPL-Caltech

The JWST was never intended to find asteroids. It was built to probe some of our deepest, most demanding questions about the cosmos: how the first stars formed, how galaxies have evolved, how planets like ours take shape, and even how life originated. However, it’s first and foremost a powerful infrared telescope and its unrivalled … Read more
