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

The appearance of the Interstellar Objects (ISOs) Oumuamua and Comet Borisov in 2017 and 2019, respectively, created a surge of interest. What were they? Where did they come from? Unfortunately, they didn’t stick around and wouldn’t cooperate with our efforts to study them in detail. Regardless, they showed us something: Milky Way objects are moving … Read more
