Galaxies die earlier than expected: Webb sees signs of halted star formation 700 million years after Big Bang
Asteroid impact threat estimates improved for the Earth and the moon

Asteroid 2024 YR4, first discovered in December 2024, triggered a first-ever notification from the International Asteroid Warning Network (IAWN) on January 29, 2025. The early calculations predicted an impact probability of 1.3% with Earth on December 22nd, 2032, and estimated its size to be between 40 and 90 meters.
New distant warm Jupiter discovered with TESS

Using the Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected a new warm Jupiter exoplanet located more than 1,000 light years away. The newfound alien world, designated TOI-2005 b, is about the size of Jupiter and orbits its host star on a highly eccentric orbit. The discovery was reported March 25 on the arXiv pre-print server.

Lunar polar regions could have microbes, modeling study suggests

Could microbes survive in the permanently shadowed regions (PSRs) of the moon? This is what a recent study presented at the 56th Lunar and Planetary Science Conference (LPSC 2025) hopes to address as a team of researchers from the United States and Canada investigated the likelihood of long-term survival for microbes in the PSR areas of the moon, which are craters located at the poles that don’t see sunlight due to the moon’s small axial tilt.
Sampling the plumes of Jupiter’s volcano moon, Io

What can a sample return mission from Jupiter’s volcanic moon, Io, teach scientists about planetary and satellite (moon) formation and evolution? This is what a recent study presented at the 56th Lunar and Planetary Science Conference (LPSC 2025) hopes to address as an international team of more than two dozen scientists discussed the benefits and challenges of a mission to Io with the goal of sampling its volcanic plumes that eject from its surface on a regular basis.
How can we find cryovolcanoes on Europa?

In the 1970s, NASA’s Voyager probes passed through Jupiter’s system and snapped pictures of its largest moons, also known as the Galilean moons. These pictures and the data they gathered offered the first hints that a global ocean may be beneath Europa’s icy crust. Moreover, planetary models indicated that Europa’s interactions with Jupiter’s powerful gravity could lead to tidal flexing in the moon’s interior. In short, scientists learned that Europa could have all the necessary ingredients for life in its interior.
A dramatic Einstein ring seen by Webb

One of the first verified predictions of general relativity is the gravitational deflection of starlight. The effect was first observed in 1919 during a total solar eclipse. Since stars appear as points of light, the effect is seen as an apparent shift in the position of stars near the eclipse. But the effect happens more generally.
Modeling lunar in-situ resource utilization can help plan future prototypes

In-situ resource utilization will likely play a major role in any future long-term settlement of the moon. However, designing such a system in advance with our current level of knowledge will prove difficult, mainly because there’s so much uncertainty around both the availability of those resources and the efficacy of the processes used to extract them.
NASA’s SPHEREx takes first images, preps to study millions of galaxies
How to engineer microbes to enable us to live on Mars

A field known as synthetic biology has become one of the most highly anticipated in science. Its outputs range from golden rice, which is genetically engineered to provide vitamin A, to advances stemming from the Human Genome Project, which successfully mapped the entire human genome. Prominent voices in biotechnology have heralded it as the next wave of the future of innovation.

Multifrequency observations explore radio galaxy 3C 111 and its jet

Using the Very Long Baseline Array (VLBA), European astronomers have carried out multi-wavelength radio observations of a radio galaxy designated 3C 111. Results of the observational campaign, published March 24 on the arXiv preprint server, shed more light on the properties of this galaxy and its relativistic jet.

Hubble’s 20-year study of Uranus yields new atmospheric insights

The ice-giant planet Uranus, which travels around the sun tipped on its side, is a weird and mysterious world. Now, in an unprecedented study spanning two decades, researchers using NASA’s Hubble Space Telescope have uncovered new insights into the planet’s atmospheric composition and dynamics. This was possible only because of Hubble’s sharp resolution, spectral capabilities, and longevity.
Costa Rica’s mudball meteorite: A cosmic survivor that avoided collisions in the pinball world of asteroids

In April 2019, rare primitive meteorites fell near the town of Aguas Zarcas in northern Costa Rica. In an article published in the journal Meteoritics & Planetary Science, an international team of researchers describes the circumstances of the fall and show that mudball meteorites are not necessarily weak.
