First Light from NASA's New PUNCH Mission

Universe Today Feed - Tue, 04/22/2025 - 12:04pm

Studying the Sun is becoming increasingly important as more and more of our infrastructure moves off the surface and into the realm where coronal mass ejections and the solar wind can begin to affect them. Scientists recognize this problem and have started devoting more and more resources to studying the Sun, specifically the "space weather" that might affect us. Recently, one of the newest members of the group of satellites focused on studying the Sun hit a milestone when the Polarimeter to Unify the Corona and Heliosphere (PUNCH) mission took on its first light.

Mars's Atmosphere Used to be Thicker. Has Curiosity Found Where it All Went?

Universe Today Feed - Tue, 04/22/2025 - 11:08am

Planetary scientists have plenty of theories about Mars and its environmental past. Two of the most widely accepted are that there was a carbon dioxide atmosphere and, at one point, liquid water on Mars' surface. However, this theory has a glaring problem: Where should the rocks have formed from the interactions between carbon dioxide and water? According to a new paper by scientists at several NASA facilities using data collected by the rover Curiosity, the answer is right under the rover's metaphorical feet.

Transformable flat-to-shape objects created using sewing technology

Matter and energy from Science Daily Feed - Tue, 04/22/2025 - 10:20am
Researchers introduced a novel method for fabricating functional flat-to-shape objects using a computer-controlled sewing machine. The team's method uses the sewing machine to stitch pockets between layers of fabric, and stiff panels are inserted into the pockets. Multiple fabrics types can be used, ranging from muslin for heavy-duty applications to more delicate fabrics for decorative purposes. The materials can also be customized on a panel-by-panel basis to adapt to each object's needs. The researchers demonstrated how the materials can be chosen to support a variety of functional goals, such as using thicker plywood for a human-weight supporting chair and custom LED panels with sheer fabric for a functional lamp. Additionally, The technique also allows for additional mechanisms such as cords, magnets, and hook-and-loop fasteners to direct and stabilize flat-to-shape transitions.

Why Webb May Never Be Able to Find Evidence of Life on Another World

Universe Today Feed - Tue, 04/22/2025 - 9:21am

The exoplanet K2-18b is generating headlines because researchers announced what could be evidence of life on the planet. The JWST detected a pair of atmospheric chemicals that on Earth are produced by living organisms. The astronomers responsible for the results are quick to remind everyone that they have not found life, only chemicals that could indicate the presence of life. The results beg a larger question, though: Can the JWST really ever detect life?
