Helium Streams Observed on Super-Puff Exoplanet
What can an exoplanet leaking helium teach astronomers about the formation and evolution of exoplanet atmospheres? This is what a recent study published in Nature Astronomy hopes to address as an international team of scientists investigated atmospheric escape on a puffy exoplanet. This study has the potential to help scientists better understand the formation and evolution of gas giant planets, specifically with many gas giant planets observed orbiting extremely close to their stars.

A Blueprint For Visiting An Interstellar Comet
arXiv:2512.00492v1 Announce Type: new Abstract: We describe how the ESA Comet Interceptor mission, which is due to launch in 2028/29 to a yet-to-be-discovered target, can provide a conceptual basis for a future mission to visit an Interstellar Object. Comet Interceptor will wait in space until a suitable long period comet is discovered, allowing rapid response to perform a fast flyby of an object that will be in the inner Solar System for only a few years; an enhanced version of this concept ...
The JWST Discovered Another Perplexing Early Galaxy
The JWST has made a name for itself by discovering mature galaxies in the Universe's early times. This time, a pair of Indian astronomers working with the JWST found a fully-formed spiral galaxy much like the Milky Way only 1.5 billion years after the Big Bang. The discovery, and others like it, are forcing scientists to reconsider their understanding of the cosmic timeline.
