NASA’s Hubble Detects First-Ever Spin Reversal of Tiny Comet
A tiny comet just did something scientists have never seen a comet do — and scientists say it probably won’t survive much longer. NASA’s Hubble revealed that comet 41P’s escaping gas has been slowly working against it, offering a rare look at how these frozen relics of the early solar system live, change, and die.
This artist’s concept depicts comet 41P as it approached the Sun and frozen gases began to sublimate off the comet’s surface. The illustration only depicts one jet, but 41P may have multiple streams of material ejecting into space. This jet is pushing against the comet’s spin, forcing it in the opposite direction.

Young 'Sun' Caught Blowing Bubble by NASA's Chandra
Our Sun has a protective bubble around it that shields Earth from the harshest space radiation, but we’ve never been able to see it from the outside. Now NASA’s Chandra has captured the first image of one of these bubbles around the Moth, a nearby star system that contains a star just like a younger, wilder version of our Sun.
The Moth offers us a better understanding of how the Sun’s wind may have shaped the early conditions of our solar system.

This 2024 image that NASA’s Hubble Space Telescope captured of the Crab Nebula, paired with its past observations and those of other telescopes, allows astronomers to study how the supernova remnant is expanding and evolving over time.

This newly processed image of the Crab Nebula comes from data originally captured by NASA’s Hubble Space Telescope in 1999 and 2000.

NASA’s Hubble Revisits Crab Nebula to Track 25 Years of Expansion
2024 and 1999
Toggling between these two Hubble images, captured 25 years apart, reveals changes in the position of the nebula's filaments relative to more distant background stars. Energy from the rapidly spinning pulsar at the nebula's core is driving the filaments outward. Some differences between the images likely relate to instrument changes on Hubble. The 1999 image was taken with Hubble's Wide Field and Planetary Camera 2 instrument, which NASA astronauts replaced with the Wide Field Camera 3 in 2009 during Hubble's last servicing mission. Each instrument took several shots to create a mosaic image of the full nebula. Wide Field Camera 3 has a slightly greater range, both in surface area and imaging filters.
