Barents Sea Tied to Low Arctic Sea Ice
Patches of open water in the region contributed to low sea ice extent across the Arctic in March 2026, which tied with the lowest maximum observed in the satellite record.

Arctic Winter Sea Ice Ties Record Low, NASA, NSIDC Scientists Find
For the second consecutive year, winter sea ice in the Arctic reached a level that matches the lowest peak observed since satellite monitoring began in 1979. On March 15, Arctic sea ice extent reached 5.52 million square miles (14.29 million…

NASA’s Hubble Detects First-Ever Spin Reversal of Tiny Comet
Astronomers using NASA’s Hubble Space Telescope have found evidence that the spinning of a small comet slowed and then reversed its direction of rotation, offering a dramatic example of how volatile activity can affect the spin and physical evolution of…

NASA’s Hubble Unexpectedly Catches Comet Breaking Up
In a happy twist of fate, NASA’s Hubble Space Telescope just witnessed a comet in the act of breaking apart. The chance of that happening while Hubble watched is extraordinarily minuscule. The findings published Wednesday in the journal Icarus. The…

Asteroid Bennu’s Rugged Surface Baffled NASA, We Finally Know Why
In one of the biggest surprises of NASA’s OSIRIS-REx mission, its target asteroid, Bennu, turned out to be a jagged, rugged world covered in large boulders, with few of the smooth patches of sandy or pebbly material scientists had expected…
