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 small bodies in the solar system. This is the first time researchers have observed evidence […]

NASA Webb, Hubble Share Most Comprehensive View of Saturn to Date

NASA’s James Webb Space Telescope and Hubble Space Telescope have teamed up to capture new views of Saturn, revealing the planet in strikingly different ways. Observing in complementary wavelengths of light, the two space observatories provide scientists with a richer, more layered understanding of the gas giant’s atmosphere. Both sense sunlight reflected from Saturn’s banded […]

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 comet K1, whose full name is C/2025 K1 (ATLAS)—not to be confused with interstellar comet […]

Listen to This Month’s ‘Planetary Parade’ With NASA’s Chandra

In late February, people in the Northern Hemisphere can look up for a special sight : Six planets will all be visible from clear and dark night skies. New sonifications from NASA’s Chandra X-ray Observatory released [day of week] will help commemorate this latest “planetary parade.” Because the planets in our solar system travel around […]

NASA’s Perseverance Mars Rover Ready to Roll for Miles in Years Ahead

After nearly five years on Mars, NASA’s Perseverance rover has traveled almost 25 miles (40 kilometers), and the mission team has been busy testing the rover’s durability and gathering new science findings on the way to a new region nicknamed “Lac de Charmes,” where it will be searching for rocks to sample in the coming […]

NASA Ignites New Golden Age of Exploration, Innovation in 2025

With a second Trump Administration at the helm in 2025, NASA marked significant progress toward the Artemis II test flight early next year, which is the first crewed mission around the Moon in more than 50 years, as well as built upon its momentum toward a human return to the lunar surface in preparation to […]
