KiDS dataset doesn’t shake up cold dark matter model after all, say researchers

Data from 41 million galaxies does not shake up the standard cosmological model after all. To that conclusion, to their own surprise, comes an international team of researchers including Koen Kuijken, professor at the Leiden Observatory.

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 […]

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 […]

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 […]

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 […]

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 […]

FAA closes investigation into Blue Origin New Glenn booster failure

The Federal Aviation Administration has said that it will allow Blue Origin’s New Glenn rocket to fly again, following a review of the January mishap in which the rocket made a successful debut launch but crashed during landing.

A step towards life on Mars? Lichens survive Martian simulation in new study

For the first time, researchers have demonstrated that certain lichen species can survive Mars-like conditions, including exposure to ionizing radiation, while maintaining a metabolically active state.

When glaciers roamed Mars

The surface of Mars is known for being an extremely cold, desiccated, and irradiated place. But as its many surface features attest, the red planet was once a warmer, wetter place with flowing water and glaciers. Today, most of the remaining water on the surface is largely confined to its polar regions in the form […]

Supernova archaeology: Finding clues in the ruins of an ancient dead star with Chandra

People often think about archaeology happening deep in jungles or inside ancient pyramids. However, a team of astronomers has shown that they can use stars and the remains they leave behind to conduct a special kind of archaeology in space.

NOAA’s GOES-19 satellite releases new coronagraph data to public

Near real-time preliminary data from NOAA’s first Compact Coronagraph (CCOR-1), a powerful solar telescope onboard the GOES-19 satellite, are now publicly accessible. GOES-19, launched in June 2024, began providing the new data through the Space Weather Prediction Center (SWPC) website as of February 25, 2025, and from the National Centers for Environmental Information (NCEI) archive […]

Experiment shows theory describing formation of interstellar benzene does not actually produce benzene

Astrophysicists at the University of Colorado’s JILA, National Institute of Science and Technology, have conducted an experiment to produce benzene the way theories have predicted it is produced in interstellar space and found it did not produce any benzene. The research by G. S. Kocheril, C. Zagorec-Marks and H. J. Lewandowski is published in the […]

The future of studying exoVenuses looks bright

What can Venus-like exoplanets, also known as exoVenuses, teach us about our own solar system and potentially finding life beyond Earth, and how can the planned Habitable Worlds Observatory (HWO) provide these insights?
