Webb Telescope Unveils Evidence of Water and Hydration on Asteroid Psyche

Posted by in categories: evolution, space

“Asteroids are leftovers from the planetary formation process, so their compositions vary depending on where they formed in the solar nebula,” said Dr. Anicia Arredondo. “Hydration that is endogenous could suggest that Psyche is not the remnant core of a protoplanet.”


Could a metallic asteroid contain water and what can this teach us about the asteroid’s formation and evolution? This is what a recent study due for publication in the Planetary Science Journal hopes to address as a team of researchers led by the Southwest Research Institute (SwRI) investigated whether the metallic asteroid Psyche —which is one of the largest objects in the main asteroid belt—could contain evidence of water and hydration.

This study holds the potential to help scientists better understand the formation and evolution of asteroids and what this can teach us about the history of the solar system. This study also comes as NASA’s Psyche spacecraft is currently en route to the Psyche asteroid and is scheduled to arrive in August 2029.

Oceans of water may be trapped deep beneath the Martian surface

Posted by in category: space

A new analysis of data collected by NASA’s InSight mission suggests there may be enough water beneath the surface of Mars to cover the planet.

Newly discovered X-ray binary system contains a white dwarf, observations find

Posted by in category: space

Astronomers from the Pennsylvania State University (PSU) and elsewhere have observed an X-ray binary system known as CXOU J005245.0–722844. They detected an X-ray outburst from this binary and found that it harbors a white dwarf star. The findings were presented in a research paper published August 2 on the pre-print server arXiv.

Scientists find oceans of water on Mars. It’s just too deep to tap

Posted by in category: space

Using seismic activity to probe the interior of Mars, geophysicists have found evidence for a large underground reservoir of liquid water—enough to fill oceans on the planet’s surface.

Probing Mars’ Interior Reveals Vast Underground Water Reservoir

“Establishing that there is a big reservoir of liquid water provides some window into what the climate was like or could be like,” said Dr. Michael Manga.


While Mars is incapable of having liquid water on its surface, what about underground, and how much could there be? This is what a recent study published in the Proceedings of the National Academy of Sciences hopes to address as a team of researchers investigated how liquid water might be present beneath the Martian surface. This study holds the potential to help researchers not only better understand the current conditions on the Red Planet, but also if these same conditions could have led to life existing on the surface in the past.

For the study, the researchers analyzed seismic data obtained by NASA’s now-retired InSight lander, which landed on Mars in 2018 and sent back valuable data regarding the interior of Mars until the mission ended in 2022. This was after mission planners determined the amount of dust that had collected on the lander’s solar panels did not allow for sufficient solar energy to keep it functioning. However, despite being expired for two years, scientists continued to pour over vast amounts of data regarding the interior of Mars.

Using corrugated wall coverings to passively cool buildings

Posted by in categories: physics, space

A team of applied physicists at Columbia University, working with a colleague from Henry M. Gunn High School, and another from the University of California, Los Angeles, has found that using corrugated siding on outdoor building walls can passively reduce wall temperatures.

In their paper published in the journal Nexus, the group describes how they added corrugated siding to a small test and found that doing so lowered the wall temperatures.

Prior research has shown that covering the tops of buildings with radiative cooling materials can reduce the amount of heat that makes its way inside by up to 20%. This is because they are made in such a way as to reflect sunlight and radiate heat into .

Celestial Light Shows: Physicists Decode the Cosmic Dance of Auroras on Earth, Jupiter, and Saturn

Posted by in categories: physics, space

A recent study reveals new insights into aurorae across Earth, Jupiter, and Saturn, highlighting the role of magnetic fields and solar winds in shaping these phenomena, with significant implications for space weather forecasting and planetary exploration.

The breathtaking aurorae, commonly known as the Northern and Southern Lights, have captivated human imagination for centuries. From May 10th to 12th, 2024, the most powerful aurora event in 21 years showcased the extraordinary beauty of these celestial light displays.

Recently, space physicists from the Department of Earth Sciences at The University of Hong Kong (HKU), including Professor Binzheng Zhang, Professor Zhonghua Yao, and Dr Junjie Chen, along with their international collaborators, have published a paper in Nature Astronomy that explores the fundamental laws governing the diverse aurorae observed across planets, such as Earth, Jupiter and Saturn. This work provides new insights into the interactions between planetary magnetic fields and solar wind, updating the textbook picture of giant planetary magnetospheres. Their findings can improve space weather forecasting, guide future planetary exploration, and inspire further comparative studies of magnetospheric environments.
