One of the primary goals of the James Webb Space Telescope (JWST) is to detect atmospheres around exoplanets, to try to suss out whether or not they could potentially support life. But, in order to do that, scientists have to know where to look, and the exoplanet has to actually have an atmosphere. While scientists know the location of about 6000 exoplanets currently, they also believe that many of them don’t have atmospheres and that, of the ones that do, many aren’t really Earth-sized. And of those, many are around stars that are too bright for our current crop of telescopes to see their atmosphere. All those restrictions mean, ultimately, even with 6000 potential candidates, the number of Earth-sized ones that we could find an atmosphere for is relatively small. So a new paper available on arXiv from Jonathan Barrientos of Cal Tech and his co-authors that describes five new exoplanets around M-dwarf stars - two of which may have an atmosphere - is big news for astrobiologists and exoplanet hunters alike.
A bevy of comets, a "blood moon" total lunar eclipse and impressive northern lights were just three of the skywatching highlights in 2025. Here's how they unfolded.
A Japanese H3 rocket suffered an anomaly during the launch of a navigation satellite on Sunday night (Dec. 21), resulting in the loss of the spacecraft.
Enjoy some out-of-this-world fun this Christmas with my selection of the best space board games available right now.
In November 2025, the interstellar comet 3I/ATLAS emerged from behind the Sun and began making its way towards the outer Solar System. This was a momentous occasion, as the comet was experiencing increased activity following its closest approach to the Sun and was once again visible to our telescopes and robotic space missions. One such mission is the European Space Agency's (ESA) JUpiter Icy Moon Explorer (JUICE), which captured the above image of 3I/ATLAS using its Navigation Camera (NavCam).
A sampling of aging Sun-like stars demonstrates that they likely eat their closest planets.
