According to a new study, researchers propose a novel theory about how the molecules of life may have developed a preferred chirality, or “handedness.” Understanding more about how the concept influences our living beings could help scientists develop drugs to fight molecular disease, like cancer.

According to a new first-of-its-kind study, dying stars that have exhausted their supply of hydrogen and are in the final stages of stellar evolution, often experience large-scale structural variations, or "glitches." Additionally, researchers say these glitches are more common than thought.

Reply to Using data from the James Webb Space Telescope, scientists were able to accidently view a supernova explosion in a nearby galaxy. According to their study, the discovery could offer new insight into the cosmos. by Impossible_Cookie596
Abstract: We present new 0.3–21 μm photometry of SN 2021aefx in the spiral galaxy NGC 1566 at +357 days after B-band maximum, including the first detection of any Type Ia supernova (SN Ia) at >15 μm. These observations follow earlier JWST observations of SN 2021aefx at +255 days after the time of maximum brightness, allowing us to probe the temporal evolution of the emission properties. We measure the fraction of flux emerging at different wavelengths and its temporal evolution. Additionally, the integrated 0.3–14 μm decay rate of Δm0.3–14 = 1.35 ± 0.05 mag/100 days is higher than the decline rate from the radioactive decay of 56Co of ∼1.2 mag/100 days. The most plausible explanation for this discrepancy is that flux is shifting to >14 μm, and future JWST observations of SNe Ia will be able to directly test this hypothesis. However, models predicting nonradiative energy loss cannot be excluded with the present data.
