In the quest to understand the fundamental forces of nature, scientists have turned their attention to a long-debated theory: ...

Because this asteroid will zoom by Earth in 2029, a detailed study of its trajectory will deliver even further restrictions on the fifth force than what Bennu could provide.

Some physicists believe that a fifth fundamental force could be the cause of some observational anomalies. A study is investigating ways to closely examine the trajectories of well-documented ...

Bennu is classified as a “potentially hazardous asteroid,” meaning the object is more than 460 feet (140 meters) wide and could theoretically come within 4.65 million miles of Earth.

In 2018, it arrived at Bennu, a near-Earth asteroid as wide as the Sears Tower is tall. The mission collected pieces of the asteroid and brought them back to Earth in 2023.

The Field Museum received a rare, pristine sample of asteroid Bennu from NASA — a "time capsule" from the early solar system, untouched for 4.6 billion years. Scientists will study the carbon ...

Asteroid 2024 YR4 captured a lot of headlines shortly after its discovery because it had a slim chance of hitting Earth. The object is estimated to be between 130 and 300 feet wide, large enough ...

A swarm of large asteroids likely lurking around Venus could one day pose an "invisible threat" to Earth if left unchecked, astronomers have warned.

Observations of asteroid (139289) 2001 KR1 made using ESA’s Flyeye telescope. These images were acquired on 21 May 2025 during the telescope’s ‘first light’ campaign.

A potentially hazardous asteroid roughly the size of an aircraft carrier is due to pass within 2.8 million miles (3.5 million km) of Earth on June 5 and you can watch it happen live online.
