NASA delayed a spacewalk that was scheduled to occur Tuesday morning, to replace broken hardware outside the International Space Station, due to a warning about possible dangerous debris.
NASA had planned for Thomas Marshburn, 61, and Kayla Barron, 34, to exit the space station about 7:10 a.m. EST for more than six hours. The spacewalk would be Marshburn's fifth and Barron's first.

A new study by University of Maryland astronomers shows that comet Bernardinelli-Bernstein (BB), the largest comet ever discovered, was active long before previously thought, meaning the ice within it is vaporizing and forming an envelope of dust and vapor known as a coma. Only one active comet has been observed farther from the sun, and it was much smaller than comet BB.

An asteroid that measures the same size as the height of the Great Pyramid of Giza, is expected to pass by Earth on Monday afternoon, according to NASA.
The 430-foot asteroid, 1994 WR12, will pass by our planet at a distance of 3.8 million miles.
