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 ...

A series of images from NASA’s OSIRIS-REx mission show the spacecraft approach and touch down on asteroid Bennu’s surface, over 200 million miles away from Earth, to collect a sample on ...

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.

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.

The proposed national US budget for 2026 contains a few nasty surprises for NASA, and some serious disappointments—among them ...

NASA's OSIRIS-REx mission, after a seven-year journey, has resulted in the collection of samples from the asteroid Bennu, promising to unveil secrets about the formation of our solar system. These ...

The asteroid appeared as a speck of light to the spacecraft’s UA-built PolyCam camera, but Bennu will seem to grow now that OSIRIS-REx has begun the approach phase of the mission.

On Sunday, Sept. 24, 2023, the spacecraft will fly by Earth and drop off what is expected to be at least a cupful of rubble it grabbed from the asteroid Bennu, closing out a seven-year quest.

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.

NASA’s OSIRIS-REx asteroid probe is giving scientists an even better look at the surface of the space rock known as Bennu now that it’s moved even closer to the object. A new photo posted by ...
