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.

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).

Engineers need good data to build lasting things. Even the designers of the Great Pyramids knew the limestone they used to build these massive structures would be steady when stacked on top of one another, even if they didn’t have tables of the compressive strength of those stones. But when attempting to build structures on other worlds, such as the Moon, engineers don’t yet know much about the local materials. Still, due to the costs of getting large amounts of materials off of Earth, they will need to learn to use those materials even for critical applications like a landing pad to support the landing / ascent of massive rockets used in re-supply operations. A new paper published in Acta Astronautica from Shirley Dyke and her team at Purdue University describes how to build a lunar landing pad with just a minimal amount of prior knowledge of the material properties of the regolith used to build it.

One of the greatest mysteries the James Webb Space Telescope (JWST) was developed to investigate was the birth of supermassive black holes (SMBHs). For more than twenty years, astronomers have puzzled over how these gravitational behemoths - weighing millions to billions of solar masses - could exist less than a billion years after the Big Bang. According to the most widely accepted cosmological models, massive black holes did not have enough time to form through the usual processes of black hole formation and mergers.

During the deployment of new space telescopes that are several critical steps each has to go through. Launch is probably the one most commonly thought of, another is “first light” of all of the instruments on the telescope. Ultimately, they’re responsible for the data the telescope is intended to collect - if they don’t work properly then the mission itself it a failure. Luckily, the Interstellar Mapping and Acceleration Probe (IMAP) recently collected first light on its 10 primary instruments, and everything seems to be in working order, according to a press release from the Southwest Research Institute who was responsible for ensuring the delivery of all 10 instruments went off without a hitch.
